                   Conserve Our Wildlife 
     The religious conservation of our wildlife means the continuance of
a natural 
resource of incalculable value, which adds measurably to the health, happiness

and prosperity of our people. 
                      SPORTSMAN'S WATCHWORD 
     We must not, as a country responsible to posterity for the handing on
of our 
resources as unimpaired as possible, neglect or wantonly destroy the unique
wealth 
of forest and stream. The sportsman's watchword must ever be- Ue without

tbuxe. 
          GOOD SPORTSMAN . . . GOOD CONSERVATIONIST 
    The artificial weapons of offence that man's intelligence has furnished
make 
him a potentially destructive adversary. But that same intelligence should
enable 
him to appreciate the limits to which his destructive bent may be carried
with 
safety. 
                        OUR RESPONSIBILITIES 
    Our responsibilities in the matter of conservation of wildlife are unmistakably

clear. The major obligation of the Game and Fisheries Branch is to maintain
an 
adequate and continuous supply of game, fur-bearers and fishes. In this the

Branch is concerned not only in the commercial aspects but also in the recreative

angle of wildlife, which, of course, cannot be measured in economic terms.

    While conservational measures can be carried to extremes, it is still
essen- 
tially true that wildlife must not be destroyed at a greater rate than it
can reproduce 
itself. Therefore, we strive to adjust the duration of open seasons in accordance

with the numerical strength and current conditions of individual species.

    Conservational laws and regulations are necessarily restrictive; but
they are 
designed solely in the interest of wildlife and not for the embarrassment
of the 
conscientious sportsman. 
                    RESTORATION OF GAME FISH 
    The Game and Fisheries Branch is keenly concerned in the problem of restora-

tion. Within recent years an intensive study of a large number of rivers
and lakes 
in different parts of the Province has been conducted by experienced biologists

for the purpose of determining the variety of game fish best suited for introduction

into such waters. Within recent years approximately 25,000,000 Pickerel fry,

35,000 Salmon Trout fingerlings, 7,000 large-mouthed Black Bass fingerlings
and 
25,000 Brook Trout fingerlings were planted in more than thirty selected
and 
scientifically-surveyed lakes and streams. 
    WE EARNESTLY SOLICIT YOUR CO-OPERATION, BECAUSE WE 
FULLY RECOGNIZE THAT THE SUCCESS OF OUR EFFORTS DEPENDS 
LARGELY ON YOU. 
 
  

					
				
				
 
 
 
 
                          FISHING 
    Residents of the Province can fish by means of angling without a license,

subject always to bag limit and seasons, as shown elsewhere in this publication.

    The following is a list of the more important varieties of fish available
to 
anglers in Manitoba waters: 
        Northern Pike                   Pickerel (or Wall-eyed Pike) 
        Yellow Perch                    Goldeyes 
        Mooneye                         Fresh Water Drum 
        Catfish                         Rock Bass 
        Lake Trout                      Grayling 
        Speckled Trout                  Arctic Charr or Trout 
    THE NORTHERN PIKE has the widest range of any of our sport or angling

fishes. It is to be found virtually in any waters where fish life exists.

    THE YELLOW PERCH AND PICKEREL (or Wall-eyed Pike) are almost 
as common as the Northern Pike. These varieties are found in waters across
the 
Province from east to west and adjacent to and within fifty or sixty miles
of the 
United States border. These waters are accessible by motor car over all-weather

roads or by rail or bus line. 
    GOLDEYE, MOONEYE, CATFISH, FRESH                WATER     DRUM     OR

SHEEPSHEAD, AND ROCK BASS are all to be found in the Red River, par- 
ticularly below St. Andrews Locks, and to a lesser degree above the locks,
as well 
as in the Assiniboine River as far west as Brandon. Lake Winnipeg is also
the 
habitat of these varieties. These waters are convenient to all-weather highways

or railways. 
    LAKE TROUT is found in many of the small, deep lakes throughout the 
rocky areas of Eastern Manitoba adjacent to the Trans-Canada highway, and
all 
the way north through the Central Manitoba Mining territory, as well as in
many 
of the lakes in the Hudson Bay Railway area. These waters are accessible
either 
by highway or railway, and beyond that by canoe or air routes. 
    ARCTIC CHARR OR TROUT is found in the tide waters of the Nelson and 
the Churchill Rivers and in fact in nearly all waters emptying into Hudson
Bay 
from the west and'south, and as far north along the west coast as is known.
It is 
equal to any of our trout. The best time for fishing is during August and

September. Accessible only by rail, canoe or air routes. 
    ARCTIC GRAYLING-This is a fish little known by the angling fraternity.

The Northern or "Maritime" portion of Manitoba offers some of the
finest grayling 
fishing in the world. It is extremely abundant in certain rivers in the vicinity
of 
Churchill and reaches a very good size. There are only eight different species
of 
grayling widely distributed throughout the northern portion of Europe, Asia
and 
America. Grayling fishing with the "dry-fly" is even better sport
than trout 
fishing. It is one of the best game fish in the world. Accessible only by
railway, 
air or canoe routes. 
    SPECKLED TROUT-Conceded the peer of all fresh water sport fishes, is

plentiful in many of Manitoba's northern waters, particularly in the Nelson
River 
and its tributaries. In abundance and individual sizes, they will hardly
be equalled 
on this continent. They are best taken by means of artificial fly or spoon.
Acces- 
sible only by railway, air or canoe routes.

Save the Forest 
 
 
    On your hunting and fishing expeditions you are pleasure bent and"
doubtless 
thrilled with the grandeur of the scenery and delighted with the evergreen
forests. 
... The scenes are enchanting today, but may be desolate tomorrow unless
you 
are careful in the use of fire. 
    Fires are the relentless enemy of the forest.... Your camp fire, lighted
match, 
cigar, cigarette, or live ashes of your pipe may destroy many square miles
of trees, 
scrubs, flowers, bird nests, game animals and other interesting things. An
aban- 
doned camp fire may even jeopardize human life. Do not leave your camp site

until every vestige of the fire is out .... Pour water on the ashes. 
    The considerate sportsman would no sooner throw a match in a keg of gun-

powder than cast a burning match in the woods. 
    Break your match in two before throwing it away. 
    Never break bottles (glass is dangerous) or leave them where the sun
may 
focus through them and start a fire. 
    MANITOBA FORESTS ARE YOUR HUNTING AND RECREATION 
GROUNDS, PLEASE HELP TO PRESERVE THEM. 
 
 
                       Avoid Accidents 
 
    Do not mar your trip by avoidable accidents .... In the pursuit of pleasure

in the wilds, accidents are too numerous, and many of them are preventable.

    Do not attempt to swim long distances in unknown waters or against strong

currents, even though you pride yourself on your prowess in home waters.

    Do not carry loaded firearms in vehicles .... Remove the cartridges from

your gun before you return to camp. 
    Make sure of your target before you press the trigger. 
    Do not over-load canoes .... See that the load is evenly distributed.

    It is never safe to stand up in a canoe. 
    The amateur canoeist should always paddle to the shore before attempting

to change seats: the experienced canoeist arranges the seating accommodation

before he embarks. 
    Remember that moss-covered rocks are slippery. 
 
 
Be Careful!

                   First Aid in Drowning 
 
    Persons completely immersed in water for even ten or fifteen minutes
have 
been restored by artificial means. Therefore, if the body is recovered within
a 
reasonable time, absence of the signs of life is not to deter immediate attempts

to restore animation. 
 
          ARTIFICIAL RESPIRATION (SCHAFER'S METHOD) 
1. illake no attempt to loosen or remove clothing. 
2. Lay the patient in a prone position (back upwards) with his head turned
to 
    one side, so as to keep his nose and mouth away from the ground. No pad
is 
    placed under the patient, nor need the tongue be drawn out, as it will
fall 
    naturally. 
3. Kneel at one side jacing the patient's head, and place the palms of your
bands 
    on his loins, one at each side, the thumbs nearly touching one another
in the 
    small of the back, and the fingers extending over the lowest ribs. Leaning
your 
    body forward, let its weight press straight downwards upon the loins
and lower 
    part of the back, thus compressing the abdomen against the ground and

    driving air out of the chest. This produces expiration. Draw back your
body 
    somewhat more rapidly and relax the pressure, but do not remove your
handx,; 
    this produces inspiration. 
4.  4lternate the movements by a rhythmic swaying backwards and forward of

    your body, twelve to fifteen times a minute, persevering until respiration
is 
    restored. 
    While performing these operations send someone, if present, to the nearest

    place to procure blankets, dry clothing, hot water bottles, etc., and
to fetch 
    a doctor, if possible. 
 
      ARRESTING HEMORRHAGE BY APPLYING TOURNIQUET 
 
1. Apply a firm pad on the pressure point. 
2. Encircle the limb by a narrow bandage with its centre over pad. 
3. Tie the ends of the bandage in a half-knot on the opposite side of the
pad. 
4. Lay the twisting stick on the half-knot, and over it tie a reef-knot.

5. Twist the stick to tighten the bandage, thereby pressing the pad upon
the 
    artery, and arresting the flow of blood. 
6. Lock the stick in position by the ends of the bandage already applied,
or by 
    another bandage passed round the stick and limb.

                      CANOEING 
    There are many types of canoe trips available for the visiting tourist
to choose 
from, ranging from a week-end to three months' duration. 
    On the waterways of Manitoba one sees nature at her best-vast marsh areas

where wild waterfowl nest and hatch in countless numbers. Some of these canoe

trips may be made without guides, but the majority traverse a country so
very 
sparsely inhabited and with such myriads of lakes and streams, along with
many 
rapids and portages, that competent guides are a necessity. 
 
          Some of the Canoe Routes recommended 
    The Whiteshell Forest Reserve' (along many lakes and streams) and the

Winnipeg River, either down to Lake Winnipeg or up to Kenora, Ontario, the

total distance depending upon the route selected. 
    From Norway House, at the north end of Lake Winnipeg, to York Factory,

on Hudson Bay, traversing Playgreen Lake, a reach of the Nelson River, numerous

small lakes to Gods Lake; thence through Knee and Swampy Lakes to the Hayes

River, and so to Hudson Bay, a distance of some 350 miles. 
    From Berens River on Lake Winnipeg, to Fort Severn, on Hudson Bay. 
This route, along the Wanipigow River, Family Lake and many smaller lakes,

Upper and Lower Severn Rivers, reaches the Bay in about 750 miles. 
    From The Pas to Port Nelson, on Hudson Bay, the tripper follows the 
Saskatchewan River, Cumberland, Athapapuskow, Cranberry, Elbow, Wekusko 
Setting, Witchai, Split and other lakes to the Nelson River, and on to the
Bay, 
covering in all about 644 miles.

     The kill of females was heaviest in early season shooting 
(September 20-october 7) when the    .peniamale ratio was 406.  feno 
 
in the late season shooting, wheu the kill was mostly iallards ant 
when there was a very decided preference on the part of man local 
 
gnners for greaneas, the ratio in this species wm       46 males to 54 
 
females. 
    Unlike the river ducks, the diving Lucks in the Delta bag showed 
 
a preponderance of males. The sex ratio of 591 birds of 4 species was 
 
52 males to 48 females (Table 2). The male-female ratio of 211 aavas- 
backs was 53 to 147. The early canvasback bag (September 20~-0ctober 1) 
was slightly heavy In females. bat for the remainder of the season the 
 
males predonenated.

     The male-female ratio of 337 losser scaups wae 5149. Beause of 
 
mild weather there was no large kill during the early flight, bAt in the

 
late season shooting (October 21-November 15) fesmles were more numerous

 
in the bag in the ratio of 45 mies to 55 fein.le. 
 
     This sex ratio in the Delta bg may not reflect the sex ratio in 
 
the Delta Marsh. Selection of drakes may distort the bUM ratio in some 
 
species; type of hunting in others. Moreover, even if we know the ratio 
 
for one marsh at one season, it would not refloet the ratio for the *oa*

 
tinental populatioa. 
 
     If, however, *W observers can make similar sex tallies for e 
 
marshes through a period of years, it is believed that valuable new light

 
can be thrown ou the sex balance of waterfowl. 
                               Age Ratios 
 
     We were unable to census all species for age ratio. With most species

 
clear-cut differences are lost early in the season and many Juvenal birds

 
are indistiuishable from adults as early as the last week in October. 
 
Lesser sesups, however, retain well-marked juvenal characters until the 
 
end of the local season, and the young blue-winged teal retain the rectrix

 
character until their departure early in the season. With these two 
 
species, then, on accurate age ratio was possible (see Table 3). 
 
                                   Table 3

     In the bag of lesser scaup there were 249 juvenal birds and 8 adults,

 
a ratio of 74.26, or 2.8 juvemals for every aWt. The sex ratios of the 
 
two age groups were quite dissimilar. The kill of youn birds was heavier

in sales (54tQ), while with the adults the females predominated (I4l59).

      The nuber of blue-winued teal taken was small, perhaps too small 
 to have statistical significance. Of 77 birds, 55 were juveials and 22 
 adults, a JuVoeal-adult ratio of 72:25, It should be mtedL that this 
 ratio is quite similar to that found with the lesser eSaup. 
 
                          Composition of Ba 
     The bag tally is more a record of what species bear the brunt of 
shooting pressure than of what species compose the local population. 
 
Shooting conditions, local shooting preferences, the habits of the 
different species, affeet the kill. The composition of the Delta bag 
 
is Kiven in Table 4.

                        Flightless Period in Ducks 
     Adult ducks and geese become flightless daring the suMmer molt. 
This is obviously a critical period and dhould be better understood. 
 
 
 
     In mid-June great gatherings of river duoks, mostly mallard* and 
pintails, were loafing on the beach of Lake Manitoba and feeding at the 
edges of the marsh, or in the oponings in the sand ridge between the 
 
  

					
				
				
-5- 
 
 
marsh and the lake. These flocks were composed largely of males rapidly 
 
losing their spring plumage and assumig the drab eclipse. Later in 
 
the month the flocks were amented by influxes of male baldpates, many 
 
still in full breeding plumage. The baldpate is not a eommon breeder 
 
here. These males presumably came from other marshes. 
 
         The congregations of males steadily grew until the second week in

 
July. Then, in a period of a few days, the gatherings dwindled and finally

 
disappeared from the lakeshore loafing grounds. Coincident with their 
 
disappearance from the loafing grounds, large numbers of flightless birds

 
appeared in the shalow bays of the marsh. Vvidently as the males became 
 
flightless ther moved to the marsh. Until now the marsh had contained 
 
only heos with broods, nesting females, and a few still mated birds, in-

 
eluding ruddies still going through their courtship performance*. Now 
 
the marsh was alive with flightless adults (flappers). As one paddled 
 
through the great bays, hundreds of birds boldly feeding in the open 
 
would make for the reeds in frantic, awkward rushes. In eight miles of 
 
travel on July 21, approximately 20,000 ducks were seen on the open 
 
water, a mere handful of which could take to the air. On several occasions

 
startled mallard drakes wore seen to drop to the water in a shower of 
 
primaries lost in the first quick strokes. 
 
         At times these flightless birds were not to be soon on open water,

 
but the reed-covered edges of the marsh fairly rattled with ducks as one

 
paddled by. Protectad loafing grounds were at a premium and old muskrat 
 
houses became feathered mounds. At mid-day on July 27 a long, narrow 
 
opening extending into the dry edge of the marsh spewed forth a stroam 
 
of flappers that passed the canoe for two solid minutes in their frantic

 
rush to water. Here several thousand birds had been loafing on an area 
 
  

					
				
				
-6- 
 
 
less than one-quarter of an acre in extent. 
 
          A few flightless drakes of blue-winred teal and mallard were 
 
seen as early as the last week in June. These early birds wore socretive,

 
being seen only in the later afternoon, evening or early morning, A 
 
spending the day in the sanctuary of the reeds. With increased numbers 
 
the birds apparently become more bold. 
 
         The peak of abunianse of flightless males in the marsh ane between

 
the second week in July and the first week in Augst. larly in August 
 
gatherings of males were again appearing on the lake shore. At this time

 
males in eclipse plumage but with new primaries were taken at the lakeshore

 
banding station.   0y august 3 mallards and pintails, probably males, were

 
flying to the stubble fields to feed. 
 
         No flightless birds were seen in the manoy closed sloughs water-

 
filled in July but dry by the first of August. Whether they actually avoid

 
resorting to dwindling waters for the flightless period is an interesting

 
but   answered question. 
 
         Adult females followed the males in the lose of the pibaries. 
 
No flightless females woer seen with young. tvidently the female does 
 
not become flightless until after her family duties are over. 
 
         The flightless flWer escapes by a freuied skittering over the 
 
surfaee. The wing strokes strike the water hard, and are so clumsy 
 
that it seems doubtful hethoer they help to propel the bird. Skittering 
 
flappers can frequently be overtaken by a canoeist. When caught in open 
 
water, all the river ducks dive roadily, often returning to the 
surface with only the top of the head and back breaking water. Then, 
 
nearly submerged, they swim slowly to the nearest cover. When diving 
 
they become rapidly exhausted and may be rather easily captured. On 
 
  

					
				
				
-T- 
 
 
one occasion a blue-winged teal flapper beoame hopelessly entangled 
 
in a bed of pondweeds after its second dive. 
 
         When taken unawares in cover, the flappmr strthees out the neck

 
and sinks slowly in the water until only the eyes and bac* are visiblet 
 
and in this posture remains motionless until dwagr has pass*., 
 
         It has bee generally believed that flightless birds are in a 
 
weakened condition. All of the birds I exmined were plump and Tery fat. 
 
         The flightless adults or flappers appear remarkably free from 
 
attacks of predators, Marsh hawks were contimally coursing the marsh 
 
edge, but on no occasion were the flappers seen to shy as the swung over.

 
The oink probably takes flappers; feathers of adult river ducks were 
 
found in mink seats collected during July. 
 
 
         Male river duek r    ained in the marsh during their flightless

 
period, but male diving ducks seemed to repair to the open lake. This 
 
is only an inference, but is supported br two kinds of evidence. 
 
         The first is that male redheadp, canvsbas, lesser scaxps and 
 
reddias disappeared from the marsh and appeared in the open lake immediately

 
after the breeding season. In the case of redheads, flights of males 
 
from the marsh to the lake were seen. 
 
          the second evidence is that throughout August, as flocks of males

 
appeared on the open lake, cast-off primaries of diving duck appeared 
 
on the beach, together with masses of pondweeds on whieh ther were 
 
evidently feeding. We found as ny as 12 primaries per yard of beach, 
 
mixed with windrows of pondweeds. 
 
          Althoug  the male deepwaters were largely absent from the nazsh
in 
 
 late summer, females in the flightless stage were frequently ensountered

 
  

					
				
				
-8- 
 
 
there after the brood season. As with the river ducks, female deep- 
 
water% with soft primries were encountered during the hunting season. 
 
         Viewing the flightless period for both the diving and river ducks,

 
I suggest the following as the probably sequence of events. The first 
 
flightless ducks are non-breeding males. These are followed by breeding 
 
males, non-breeding females and unsuccessful females. The last birds to 
 
lose the primaries are the successful females. The flightless blue-winged

 
teal and mallard~s seen in late June were already in their clips* plumage,

 
but were still identifiable as males. At the same time the males attending

 
females were still in brilliant spring plumage. A few females were seen 
 
with the great gatherings of males on the lakeshore in June, and a few 
 
flightless females were so   with the gatherings of flightless mals in 
 
July. Flightless females, however, were not seen in sy mnmbers until 
 
August and & lesser scaup with a very young brood at the end of August

 
had not lost her primaries. I conclude from all this that the non- 
 
breeding and unsuccessful females become flightless early, while the 
 
successful females retain their powers of flight until after their broods

 
are independent. 
 
         This preliminary work raises several questions important to 
 
 
manageent. 
 
         Why do females predominate in the Delta bag of river dueks? Doe

 
their belated molt detain them on the breeding grounds? 
 
         Does a bag tally reflect the true sex ratio om a waterfowl shool

 
groundsT How mnch does differential migration, type of hunting, and 
 
selective shooting affect the sex ratio of the killt 
 
         What Is thenormal ratio of youag to old ducks? The ratios here 
 
reported for two species will have meaning only after similar ratios are

         FEBRUARY 13 to 17, 1939 
 
 
Dear Aldot 
 
                Let me assure you that we have considered, upon 
your advice, the Delta project as a definite part of our 
program. We do not think we'll have any trouble in finding 
funds to follow through on this project during the comihg year. 
 
                I think it would be a very constructive plan for 
you to arrange a conference between Mr. Bell, Dr. Miles Pirnie, 
Mr. Hochbaum and yourself in the near future so that we will 
have a better idea of -what we shall attempt to do at Delta 
next year and what the activities will cost* I would like very 
much to be personally present at such a conference. 
 
                We are going to have to lay soae local ground 
work at Detroit for the Fourth North American Wildlife Conference 
pretty soon. Perhaps I, or some other member of the Institute's 
staff, could arrange to kill two birds with one stone--by 
attending your proposed oonferenoe with Mr. Bell and also work 
out some details at Detroit at approximately the some time. 
 
                Please see what dates will be convenient for all 
those comerned and we will try to make our plans accordingly. 
In the meantime don't forget that we are trying to arrange a 
conference for you with the Sloan Foundation. 
 
 
With kindest regards, I am

               Dear Miles: 
                        Albert got back yesterday an brought with him 
               the attached letter from Cartwright (please return). His 
               reply, which is enclosed purposely stalls the answer. 
 
                        I think we should have our oonference with Mr. 
               ell before replying. However, before we can effectively 
               have our confereace we must know somethig about probable 
               Institute support for next year. Accordingly I have 
               written Henry Davis the attached letter. As soon as I 
               hear from him I will try to get Mr. Bell to set a date for

               the conference. 
                                        Sinoerely yours,

   Dear Dr. LeoPola: 
 
   First, my apologies for failure to acknowledge and 
   thank you for copy of your letter of September 1st 
   addressed to Mr. Davis, together with your report 
   on the Delta Project. 
 
   This was lost in an accumulation of mail while I 
   was away this summer and did not receive my 
   attention before I went North. 
 
   Certainly the work you have started at Delta 
   has me- with enthusiastic interest and support 
   and we are all delighted with it. I am so sorry 
   I could not have been there with you and Dr. Pirnie. 
   Hochbaum seems like an extr mely able young chap. 
 
   I did not have before me the suggestions you made 
   about the winter carry overs, but Hochbaum was 
   familiar with it and I gave instructions to Ward 
   that they should be followed out as you indicated 
   through Hochbaum. This I am sure will be accomplish- 
   ed to your satisfaction. 
 
   I did greatly enjoy reading your report and I am 
   encouraged in the thought that we have really done 
   something useful and that this may be continued with 
   increasing usefulness in the future.   I shall be 
   glad to confer with you and Dr. Pirnie at any time 
   you may elect.   Possibly we can find a convenient 
   date whuen we can both be in Chicago. 
 
   With kindest oersonpl rcga.ds, I am, 
 
                              Yours sincerely, 
 
   JFB-G

       Acting President J. W, Stack, after consultation with 
       the other officers of the Association, has called a 
       business meeting to be held at the Museum of Zoology, 
       Ann Arbor, Mich., Friday afternoon, Nov. 25, 1938. 
       This will follow, immediately, the program of that 
       day of the Wilson Ornithological Club. 
 
       There is an important election to be held at the time 
       and questions to be discussed having a bearing on the 
       future of bird banding organizations. 
 
       There will be no formal program but papers may be 
       submitted to the Secretary to be read by title.   These 
       will be published later in Inland Bird Banding News. 
 
       A notice of the meeting, giving all particulars, will 
       be mailed, about November 1, to each member.

    DELTA BEACH WILD DUCK HATCHERY AIDS MIGRATION STUDIES 
                     by M.D.Pirnie 
     In Canada is located one of the least known but one of the 
most important duck banding stations in North America.   It is 
owned by James F. Bell of Minneapolis and is in charge of 
Superintendent Edward Ward.   This duck hatchery has raised and 
leg-banded over 60QO. wild ducks in the past six years for release 
at the Delta Marshes of Man-itoba.  (At the south end of Lake 
Manitoba, about 70 miles west of Winnipeg.)   The species banded 
include the Mallard,.Pintail, Redhead, Canvasback, and Lesser 
Scaup,   This has been truly a pioneering work. for nowhere else 
have the Redheads, Canvasbacks and Pintails been raised success- 
fully in such large numbers. 
     Banding returns received to date show that the Pintails and 
Mallards raised at Delta have held very close to the Mississippi 
fly-way. The Lesser Scaups and Canvasbacks have .spread more 
widely and some have been shot at the Atlantic Coast. 
     During the past August, the writer was at the Delta Marshes 
for waterfowl plumage studies sponsored by the American Wildlife 
Institute, Michigan State College, and by the University of 
Wisconsin.   Professor Aldo Leopold spent the last week of August 
at Delta to confer with me and H.A.Hockbaum, one of his graduate 
students at the University of WisconsIn.   Mr. Hochbaum is banding 
ducks and is otherwise busy with intensive waterfowl studies at 
the Delta Marshes for a five-month period which began last June. 
He trapped 27 Blue-winged Teal in one "haul," and reports taking

young Ruddy Ducks and Redheads in his funnel traps.

Up to the present time we have banded more than 51,000 birds in 
the past 12 yearsý   Since January lst, 1938, we have received 
195 returns through the Biological Survey.   Some of them are most 
interesting.   I don't remember now how many returns in all we 
have received but it runs into a great many hundred. We have,*had 
reports fr6M thirty-one different states and eight foreign coun- 
tries, including several provinces of Canada. We are making maps 
of each species of bird, showing where they have been recovered.     -

                     Glad to hear from you. The bag tally intreats me

Dear Professor Leopold, 
 
       I am afraid the temptation to slip out with the gun 
in any spare moment has been too great and I have let my 
correspondence sldde. It is a new experience to shoot ducks 
at ones very door.   Thank you for the new Riley Program and 
for the note from the boys. Must have served three Cocktails 
this time! 
 
       It has been a busy place here with guests coming and 
going every day. Mr. Bell arrives today and I am looking 
foreward to meeting him and going over our program. Since 
the opening day there have been 280 ducks shot and I believe 
that, even with this small number,you will be interested in 
the record. 
 
       Males    124   Adults     146 Adult M. 64 Juvenile M.60 
       Females 156    Juveniles 134 Adult F. 82 Juvenile F.74 
 
As L look over the records I am a bit concerned with the number 
of juvenile birds as compared with adults,but I have gone over 
all of the birds very carefully and the juvenile characteristics 
are still quite obvious on most of the birds I have seen. I have 
saved tail feathers and the wing or parts of the wing of each 
birds so that I will be able to check the records again. 
 
       Mallards head the list becausewith the June weatker we have 
been having a great deal of the hunting has been jump shooting. 
For the maliard the record is as follows: 
       Males 45   Adults 79 A.M. 31   J.M.14 
       Females 75 Juv.   41 A.F. 48 J.F.27 
 
       Shooting will continue at the lodge until the third week 
in October Ward says andwith the prospects of looking at over 
a thousand birds, I think these records should prove interesting. 
After that,the local game guardian has kindly consented to let 
me look at bags with him on Fridays and Saturdays until the end 
of the season. 
 
       The most surprising thing about the season here is the 
small amount of shooting that is done. Except on Saturdays when 
th-re is a small amount of shooting, one seldom hears a shot all 
dayt long. There is almost no shooting at all *mam east of the 
far lodge. 
 
  

					
				
				
 
 
 
       After I had written you last, I realized that it was too 
late to reach Mr. Elton in Ottawa by mail, and then car troubles 
complicated things for a trip to Winnipeg. I did get in and 
had a chance to talk with him for a shott while which made me 
all the more sorry that I could not have made better arrangements. 
 
       Here is an item that calls for a good deal of thought, 
considering our discussions regarding personnel,difficulties 
of maintaining a large staff here at the present time,and 
relations with Ducks Unlimited. Mr. Pitblado wants to have 
a University of Winnipeg student to work as an assistant under 
our direction here next summer. He seems to know where funds 
are available and his object, as he stated it, is to bring about 
an interest in this type of prworkm at the University. 
 
       You will be interested to know that the 14atural History 
Society of Winnipeg has asked my to give a talk next month. 
 
       Thank you for the troubles to which you have gone 
concerning enrollment in the University. I am not perturbed 
over being unaffiliated for a few months, 
 
       The plant used so much for snow fences here is Caragana. 
I am not familiar with it and can't find it in my booksbut 
you probably know what it is. 
 
       Hope you -ill enjoy a pleasant shooting season at Riley 
and that you bag a deer this year. Wish you could drop up 
here for a few days this fall. 
 
                        Yours sincerely,

                                         Thank you very much for your letter
of 
                            September Ist attaching the report on the Delta

                            project. We would like very much to give this

                            project quite a bit of publicity. You suggest
that 
                            "the technical conclusions be given no publicity

                            at this time". Naturally, we will abide
by this. 
                            But we would like very much to "tell the
world" 
                            that we are engaged in a waterfowl study and
mention 
                            what type of work is being undertaken. 
 
                                         I'm sending copies of this report
on to 
                            the officers of the Institute. Many, many thanks

                            for your splendid cooperation.

                 Dear Mr. Leopold: 
 
                         I did not expect to let a week elapse 
                 before telling you again how much I enjoyed your 
                 visit at Delta, and especially the trip back and 
                 my stop-over at your home. I had a fine rest. 
                 Please thank Mrs. Leopold for me. 
 
                         I have again read the report to the Institute 
                 and to Mr. Bell. I am sure you have covered all of 
                 what had seemed to Albert and me essential items. In 
                 spite of a fail- start in plumage determinations of 
                 age and sex, I realize there is much hard work yet 
                 to be done in this part of the study; and I hope 
                 that it may be possible to greatly expand our local 
                 duck propagation as well as to make full use of the 
                 Delta Wild Duck Hatchery program. 
 
                         Enclosed are sample record sheets. [he 
                 printed one is used for birds or mammals, and it 
                 certainly savey work and prevents many omissions. 
                 Our field sheet for banding records is being revised 
                 to include a column for weights. Other suggestions 
                 will be appreciated. The ruled sheet for posting 
                 all bandings seems very satisfactory, provided the 
                 cause of death-when known- is recorded so as to 
                 permit tabulations of shooting mortality, etc. I 
                 believe repeats ( weights, etc.) can best be taken 
                 care of by a card file for all repeaters. Other data, 
                 weights and plumage records, etc. can be taken from 
                 field sheets directly. A card file for all bandings 
                 seems cumbersome and unworkable. Still need for study. 
 
                         A small enlargement of the dowitchers is 
                 on the way. Expect to send you several others when 
                 we get doing our own this winter. -- The color 
                 films are fine, including straw fires. Am anxious 
                 to finish them as slides so you can borrow some.

Dear fteary 
 
          I am jut bak from Delta and am enthusiastic aboxt the start which

Pirnte sa Hoobbaum have adAe, and hardly lees about the excellent cooperation

between them and Mr. 14110a organizatioa on the ground. 
 
          Mr. 3.11 is still in ScotlwA and I shall have no imediate opportunity

to confer with you and the other officers of the Institute. Hesce I have
had to 
make the budgetary eepeots of the attached report tentative rather than final.

So man possIbilities are opened up at Delta that I need to confer with you
and 
with Mr. Sell and learn something of your wishee before I ca wAke a final
rocom- 
meadation for 1939 orpaisation. 
 
          I have seat copies of the report to Mr. Bsll, Dr. Pirnie, Hoebm
and 
Mr. Wd, and as circulatlag a copy among member. of the Techncal Committee.

Will you kindly Sve the attached copy the necessary airoulation among officers

of the Institute? 
 
          I would sugest that the technical eonelusions be given no publicity

at %tis time. *r. Bell has wisely followe*d this ease policy in recent yoers.

Some of those conclusions night be snatched at and possibly misused by other

orgnimations. There are. of course, maw things about the project which could

be safely publicised even new, but I think this should await the determination

of fttue objectives I personal soomfrence with the Lastitute and Mr. 3e1l.

 
          I am glad to tell you that relations with the usaAian authorities

are oxeellent. I called em Mr. CuaniAam, the Provinoial gaue officer, and
foeud 
him very friendly toward the whole uAdertaking. Several flyway officers of
the 
R1iological Survey have dropped In and expressed enthusiasm for the usefulneas
of 
the results which will shortly be forthcoming from this project. 
 
          A& aceounting for the 1938 gratnt from the Institute will be
submitted 
to you by Dr. Plrote as soon as the season Is over, namely %bout November
15.

Dear Albert: 
         low that I have had a chance to collect iq thoughts, I think of

& few things we should have talked about. 
 
         aawim. I would like to have you take enou         time off to do

aditional painting  readesof wJ lose of tohnt           output. How Mcht

I will leave to you. 
 
          BI suspect that we overlooked somthing In Table I 
of the rep.    I dut If eaptive stock ti available this year for all of 
the nine secie proposed for eo-ge         on b  n    , T4     1y I 
have left a loophole La the report and will simply leave it to you and Mr.

Ward to make any necessary adjustment, suabjet, of course, to Pirni*es O.K.

There is, of course, no reason why part of the plumage lots cannot come 
from wild eggs next year. 
          AI have talked over the relationship 
between Fi   e and Ward a respect of artfic.ial propagation next year &ad

Pirnie and I find ourselves in entire agreement, namely, we will give 
a&Ice on artificial prpagation only as Mr. Ward asks for it. 
 
          Wtloa $taja. I have a further letter from Michigan State and 
have ain attemted to exlain the atter to them.        I suggest that you
send 
Vivian your fees on a resident tmcis, and if we do not get resident status,

that you do not register during the first semester. I will try to get straight

with Michigan by that time. 
 
          Mr. and Mrs. lton will be in Winnipeg September 16-21, c/o The

Fur Trade Oommissioner, Hudson's By Compaoq, Hudson's Day House. From 
September 5 to 11 they will be c/o Dr. R. U. Anderson., National Miasma.,
Ottawa. 
 
          In closing let me again tell you of my satisfaction over the whole

job as you and Pirnie have conducted it. 
                                   You"s sincerely,

    Dear Dr. Huat: 
 
              This spring Dr. Pirnle. with my help, obtained a $1,000 grant
from 
    the American Wildlife Institute to make a duck study in Manitoba. 
 
              The field work required a student of special qualifications
and Pirnie 
    selected one of my students, Albert Hoohbaum, as better qualified than
any of 
    his available men. Hoohbaum has been at work all mumer and is being paid
by 
    Michigan State College from Institute funds deposited with you. 
 
              This winter about November 15 Hoehbaum will return here to
work up 
    his field data and prepare for next year's field work. He will register
this 
    fall in our Graduate School. The question is, "Mist he register
as a non- 
    resident student (he comes from Washington, D. C. ) or can he register
as a 
    student given the benefit of resident fees because he is doing research
work for 
    the University? 
 
              At this university all students supported by university -ante
get 
    resident tuition privileges even though they may be non-residents. Non-resident

    tuition is $100, resident tuition is $2.750. Dean 1. B. Jred of our Graduate

    School told me he would be glad to recommend to the Regents that they
extend 
    resident tuition privileges to Rochbaum if Michigan State College would
certify 
    that he is doing satisfactory research work Jointly for the two institutions
and 
    is receiving a stipend from Michigan from a grant for such work. 
 
               The question is of official importance to both tieconein and
Michigan 
    State because Eochbauu is supported in part by his savings, the stipend
for 
    summer work being insuffioient to carry his personal expenses. Now that
he has 
    been especially trained for the job it is important to both of us that
he be 
    financially able to hold out long enough to finish the Job. If he has
to pay 
    non-resident tuition he will naturally be able to hold out for a shorter
period 
    than if he can be accorded resident tuition status. If the grant had
been made 
    to Wisconsin instead of to Michigan State, he would atomatically have
resident 
    tuition status. Since, however, this is a Joint undertaking between the
two 
    universities, I thought it would be to our matual interest if you wrote
to Dean 
    Fred, suggesting that he extend resident tuition status to Hochbaum.

 
              As to his qualifications and the satisfactoriness of his work,
I 
    would prefer that you see Pirnie. Both of us are enthusiastic about Hochbaum

    and believe it would be very difficult to locate another man anywhere
near as 
    good.

          I am sorry to have to bother you with this long explanation and

appreciate your friendly inquiry. 
 
          I might add in closing that I have a high admiration for the 
services which Dr. Pirnie has contributed to our project. If you have time

to read it, you might ask him for the progress report which he and I have

just drawn. In m opinion this project provides a channel for making useful

on a national scale all of the findings which you have been accumulating
at 
the Kello4 SanctuAry.

     Dear Professor Leopold: 
 
                      I have just received a letter from Dr. Pirnie mailed
from 
     a town in Manitoba asking that a Mr. Hochbaum be given resident status.
I 
     am not quite sure as to just what Dr. Pirnie means# I am not acquainted
with 
     Mr. Hochbaum and I know nothing about his record or abilities as a student.

     Would you be so kind as to explain just what you and Dr. Pirnie wish
to have 
     done concerning Mr. Hochbaunmand give me your estimate of him from the

     standpoint of his ability, preparation and personality. 
 
                      We hope to see you in East Lansing again sometime before

     long. The recollections of our contacts are very pleasant to me.

Dear Prof. Leopold: 
 
       At the end of ten days at the Delta marshes 
with Albert, I feel qualified to report on the progress 
of the waterfowl study. In brief, both in public 
relations and in wildlife research I consider he has 
done an enviable job. His findings substantiate our 
hunches that censusing nesting waterfowl and "productivity' 
are exceedingly difficult,- that several years work and 
study in a marsh such as this would yield considerable 
base data for other waterfowl field work ,- and that 
the Delta Duck Hatchery can be very useful in studies 
of duck growth and plumage development. (Aids in taking 
inventories of broods and in sorting bags of ducks.) 
 
       The enclosed progress report from Albert is 
quite adequate for now, I believe, to give a good idea 
of accomplishments to date. A general inventory of 
a situation and marsh yields few specimens than a 
collecting trip, fewer nests than a nest study,,etc., 
but is, I believe, none the less valuble to wildlife 
management. And in this case I consider the details 
and specimens are of themselves a credit to the study. 
 
       To summarize: We are getting a photographic 
record (chiefly in color) of the marsh stations likely 
to be of importance in future studies, of birds and 
mimmala, habitats and special plants.  Albert has 
painted sketches of the downy young of 8 duck species. 
Forty specimens of ducks in various stages of development 
have been prepared to date. Five duck traps have been 
built and 115 &icks--mostly young- have been banded. 
(Baiting young ducks is far from easy, we find.) 
In predator study, 80 ground squirrel stomachs (Franklin's) 
50 mink scats, and 50 crow stomachs have been collected. 
In an intensive nest survey, 21 nests were found on 15 
acres; where incidentally, early nests have been robbed 
for the hatchery. Brood observations number over 500.

            Current work includes completion of about 15 more 
       duck skins, juvenals and eclipse canvasbacks and redheads 
       of known age, hatchery birds; more photos of broods, etc.; 
       new traps and still more active banding efforts; more 
       marsh trips to locate new concentrations and *moving out'; 
       Fall work will include the tally of ducks bagged together 
       with listings of species seen in the marsh and redative 
       abundance. We plan to set up stations for marsh plant 
       ecology studies. Muskrats and algae- also milfoil- seem 
       likely to greatly affect other plants, but water fluctuations 
       may be even more important. 
 
              Mr. Ward has insisted on making tentative plans for 
       next year's duck rearing program; and,with no obligations 
       to the Institute, we are offering some suggestions. We 
       could have the use of extensive mink pens which seem very 
       suitable for starting young ducks. Ward is prepared to 
       build additional outside pens and to adapt his program 
       in the hatchery to suit the needs of plumage and species 
       studies, according to our needs. A wonderful chance, it 
       seems. 
 
              In taldng of possible future studies, Albert and 
       I boil down the opportunity to about the following, in 
       brief: 
              1. A full season study of waterfowl -....ni   __ 
              nesting in a Phragmites-Scirpus marsh. 
 
                 Detailed study of duck development, weights and 
           (..-'plumage changes, for age determination, sexing, etc. 
 STUDY 
OBJECTIVES    ,. An evaluation of and contributions to artificial 
               propagation of ducks. Chiefly Ward's Program. 
 
               4. Study of flocking, migration, and dispersal by 
               means of the leg-banding. 
 
               5. Preparation (with Ward) of report on banding 
               results to date, and on artificial propagation; 
               also other reports and papers for publication as 
               data gathered seem to warrant, eventually including 
               the identification "text" Albert and I have taked
of. 
 
       Without doubt, the above objectives mn be fairly well 
       accomplished should it be possible to operate with at least 
       the present personnel and aids from the Institute and 
       from Mr. Bell. I trust that this season's results will 
       cause you to hold the same opinion.-- We look forward to 
       your visit; and still have funds for all or most of your 
       expenses one way. ** Have written Dr. Hunt as to letter 
       to Dean Fred.-- Advise if you wish special report to Davis 
       prepared by us now. We assume otherwise you will report 
       informally on basis of this letter and report. Thanks. 
 
                           Sincerely, 
 
  

					
				
				
 
 
 
 
 
 
 
     In a conference with Miles Pirnie on Augst 1 the following list of 
unanswered questions about duck nesting was drawn up. 
 
qZL& A. Qestions not likely to be investigtad by others. 
 
     1. Oat species renestT What species, if an, have second broods? 
        Is either character changed by domestication? 
 
     2. What per cent of birds on breoding marshes are actually breedingT

        What per cent are paired but not nesting? What is the age of first

        breeding In the various sposeis sad how does this-affect the first

        two questions? 
 
     3. What are the criteria of stage of incubation in duck es?    What
are 
        the criteria of age in ducklings? (Moedod for mortality and predation

        studies.) 
 
     4. Can plumage orltoria be developed for oclsifying the duck bag of

        the various *peel   by sex and sgO?  (Xoedod for productivity studies.)

 
Group X.    eostions whim might be investigated by others, but have not been

sficiently ostuded. 
 
     5. Is it possible to got productivity measuresment on sample units of

        broeding ground? Row? What kind of unite? (lsrniss' work indicates

        this is feasible on potholes. Staudt's work shows promise for lake

        shores.) 
 
     6. Can nest density samples be obtained by burning sample areas? 
 
     7. low ean grasing, fire, cultivation, and barbed wire be used for cover

        improvement on nesting grounds? 
 
     S. What ref inments of technique for identifying nest predators can
be 
        developed? 
 
SC.         estions not investigated by others and not yet approachablo for

  lak ftecnque. 
 
     9. What is the carrying capacity of typical nesting grounds?  To what

        xtent are they under-stocked? Is carrying capacity determinable by

        xperimental manipulation of sa kind (such as planting additional

        breeding stock) or mast it be historically determined, as by 'rrington

        in quail? If the latter, how should sample plots be loated and 
        measured? 
 
 
     It ws agreed that these approaches to waterfowl nesting problems are
as 
yet crude and therefore likely to profit by repeated discussion. The group

interested in them is in part scattered and not able to hear such discussion.

Dear Professor Leopold: 
 
       Certainly am glad to know that you have decided to 
visit Delta. I know you will find it a great place. 
 
       Thank you for sending me the announcement and the 
outline for the new course. It is very clear and quite brief 
enough, I believe, and I can offer little in the way of 
suggestions. I am enthusiastic about the new course, it is 
great. My only feeling is that it should stop at three credits. 
The Saturday field trips should be an important part of the 
course, but I believe the work outlined on page three should 
come under 161. 118 might well be a prerequisite for this 
work but could it be carried along with the course? Again, 
it will mean two groups of students under individual supervision 
rat  r than one. Thii   ara ra h describes work that I believe 
might  e o  ere   o students in other fields in 161. This is 
but a minor point and my perspective on school work may be a bit 
warped way up here. 
       Your outline of the purpose of the course certainly 
carries a great deal for thought. 
       Trapping started with a ban   ut has dropped off a bit 
 in the last few days. Have taken'35 young ducks and believe 
 I can take several hundred before the season is over. Mr. Kalmbach 
 informed Mr. Ward that he, too, intends to band young ducks this 
 year, though he has not started as yet. 
       Have had over 50% good luck on picturesthough the 
bright lights here fool one. Here are a couple of nest pictures 
taken with your camera. 
        Enclosed is an outline of progress during July as 
 requested by Pirnie for his visit with you August 1. 
        Hoping to see you at Delta soon, 
                                 Yours sincerely, 
 
  

					
				
				
 
 
Outline of ,rogress for July 
 
 
1: Field work 
       As much time as possible has been given to reconnoitering 
the marsh, particularly Bell's land. This has been justified, 
I believe, because any work we do here must be preceded by a 
knowledge of the area. Frankly I have been absorbing as much 
as possible about ducks, this being my f6rst opportunity to gain 
first-hand knowledge of them on the beeeding grounds. 
 
       I believe I have some interesting notes on birds during 
the flightless stage of the eclipse. This is apparently near 
its peak now and Ward and I estimated that about 75% of the 
birds seen in a trip through the marsh on thursday were flappers. 
Flightless birds of seweral species were seen the last week in 
June. Their increased abundance in the marsh was noticed shortlp 
after the disappearance of the large flocks of males that 
frequented the lakeshore until about Jut* 10. 
 
       Considerable attention has been given to brood observations, 
and I have observed about 300 broods, mostly redheads, canvasback, 
and ruddy. 
 
       Of the predators the most interesting object of study is 
the Franklin.s ground squirrel, more abundant on the marsh 
borders than I have ever seen a mammal.of its size. We have seen 
them kill a young duck and have found numerous others they have 
taken. I have a collection of crow stomachs, ground squirrel 
stomachs and mink feces for later study. 
 
2; Banding and Trapping 
 
       Two traps are now going and tkree more are under construction. 
I have banded 35 young redheads,pintails, mallards and blue-winged 
teal. 
 
I: Skin collection 
       A beginning has been made on a collection of downy young as 
well as birds in eclipse plumage. Color sketches of downy young 
of several species have been made for future reference. The 
collecting permit has arrived from bud* Ottawa. Incidentally, 
redheads and bluebills have been immima"  NO    *collected 
in flightless stage because df feather-wear before the primaries 
are lost. Peter Ward is becomming adept at preparing skins and 
may be of help later on. 
 
4. The Hatchery 
 
       Eight species are now under observation for plumage 
developments, etc. 
       Ward has banded and released 437 of his own birds,cans, 
redheads,pintails and mallards. 100 birds have been sent to 
the Bio. Survey for experiments in changing birds from one 
flyway to another. 
 
  

					
				
				
 
                        -2- 
 
       Ward has saved about 50anvasba.ck and redheads for 
us and is going to release the adult birds now in the channel 
pen. Some of these birds might as bell be burtled as released 
and we wonder if it might be worthwhile to run some experiments on 
them -- differential mortalitt in lead poisoning etc.

                         Dear Aldos 
 
                                      You will note from the attached copy
of a 
                         letter I've Just written to Dr* Huston that Dr.
Pirnie 
                         has outlined the plan for the expenditure of the

                         $1,000.00 which the Institute has appropriated for
the 
                         Delta, Manitoba, duck study. This arrangement is
entirely 
                         satisfactory to us and I hope it meets with your

                         approval. 
 
                                      We will look forward with a great deal
of 
                         interest to Dr. Pirnie's progress report. I think
this 
                         project is going to be very worthwhile. 
 
                                      With personal regards, I am 
 
 
 
 
 
                                                                   erly yours,

             Delta, Manitoba 
             Canada 
 
             Dear Albert: 
 
                       I am much pleased with your letter, partimlarily 
             with the good news that you and Mr. Ward get along so nicely

             and that you have so high an opinion of his abilities. 
 
                       I circulated the Williams report with the intention

             of calling it up at seminar and seeing which of you boys coxuld

             do the best job of shooting it full of holes. My opinion of
it 
             is the same as Mr. Ward's. Do you know this is the vi.me 
             Williams as is co-author of the excellent paper by Y.arshall
and 
             Williams? One can't help drawing a flatteriag inference as to

             Marshall. 
 
                       I appreciate you and Miles both urging me to cone
up, 
             but I know I can't at present and I cannot promise later. 
 
                       Don' t worry about. a program not imiediately sha-piu

             itself. It should not. Your notes sound goof and the whole 
             thing will shake itself down soon enough. 
 
                       With best regards, 
 
                                             Yours sincerely,

        Dear Miles: 
 
                  I am glad you and Albert were pleased with ycur first 
        impressions, andT axn especially glad to kaow of your good 
        opinion of W7rd. 
 
                  The letter to 7ean "rrd has for its purpose the orpor-

        tu-ity for Albert to pa? resident rather th0en no-resident tuitioa.

        If he were supported on a piece of research by a UnIversity of 
        Wisconsin assistantship, he would automatically get the 1bnfit 
        of resident tuition. Sine his employment by Michigan is virtually

        the snae thing as far as resaerch is concerned, I theouat your Dam

        would be willing to write a letter of the kind I sent you, and it

        would save Albert $200 out of his none too large salar, You 
        understand, of course, that he Is supporting himself for the whle

        year out of what he erns this umer. I of course ao not want 
        you to do anything which embarrasses you. Dean Fred tells me, 
        however, that these mxchairqt of courtesy between collges. are not

        Inf requesnt. 
 
                  I a-.preciate your urging me to go up to Delta in Augst.

        I cant yet tell whether this will be possible. 
 
                  Your letter to Mr. Bell is very well handled. 
 
                                      Yours sincerely,

 Dear Mr. Leopold: 
 
           Just to reply to your letters and first 
 of all to say that Al and I were more than well 
 pleased at our "take-off" with Ward at Delta, and we 
 found facilities excellent and propitious. The 
 dopy of my letter to Al (enclosed) will sumnf up the 
 present emphasis on field and lab work for him. Any 
 suggestions? He read me parts of his letter to you, 
 so I feel you have by this time a fair notion of the 
 setting, habitats, etc. 
 
           As to the letter to Dean Fred: I am rather 
 puzg led as to the letter which would be in order 
 coming from Michigan State. The idea you want put over, 
 if I get you, is that he will be on the job into 
 November, and not working just in regular collepe 
 terms; but actually he will be doing research for 
 which you feel he should heve College credits. But 
 are we at this end in position to enter this discuasion? 
 I do not understand the details of your tuition request. 
 
           As to the paying out of the expense money and 
Alt' nlary: I have written the College and shall again 
write Levis when I have their reply, sending you a copy 
of my lelter to him. 
 
           There should be money for your travel to 
Winnipeg in August if you can find time. Better plan 
on it, Al and I agree. 
 
          I am increasingly impressed by Ward as well 
as by Albert's ability and balance. Evidently it is 
up to us to plan someway to utilize this combination 
in the future-- provided Mr. Bell can see his way to 
aid; or in case he backs out, we should find another 
sponsor. 4e-ehsaee Thr. chance is too good to lose. 
 
                  Sincerely, 
 
 
                     Miles D. Pirnie.

          Aa you my know by this time, Hochbaum 
(the student) and I went to Delta on tne 12th, and 
althouih of couree I had to return here for teeching 
in the    >er J:hool of Alology, he Is now well at 
the waterfowl studies- thanks to your hoplity 
and the hv   from t7!e .ildlife Institte. 
 
          I am very much impressed by the work .r. 
lard hoe done; and in fret it is not -tretching the 
frcts to say he i1 way out ahead of the so-celled 
*wildlife specieliets' who are so lacking in experience 
that they cannot prop erly evaluate his rork. i 
consiler it a rewl privilege to be a le to leern 
from and to wYrk wit him under so fine a Let-up. 
 
          Piather than take your time by tryirn to 
write in greeter detail, let me V-rely eSy at this 
tiuie that I sincerely hope you may find a chance to 
be at Delta for a few d&ys when I have returned or 
the month of August. 
 
          I expect that .r. ioeum will fit in end 
get alorn very nicely at Dlta. He made good in the 
'ation-l 1Parks .ervice and le one of the nost capble 
workers I know- in eadltlon to bern well along as 
a bird artist. 
 
          Aiain fiuy I express mr týizrks for what you 
are doin to aid our waterfowl nesting studAee,

            your bailiwick and I didn't wvant to start anything in that fiel.

        Dear Aldo: 
 
               I have your letter of June 14 and in reply I may say that

        for some reason I seem to be on record as being uninterested in the

        artificial propagation of waterfowl. The truth of the matter is 
        exactly the reverse, provided the birds to be propagated are not

        puddle-duck Mallards. 
 
               This project of Mr. Bell's at Delta, Manitoba, has been 
        watched by me for several years and I feel that he is really accom-

        plishing something decidedly worth while. He and I have had con-

        siderable correspondence on the subject and his Superintendent, !r.

        Edward Ward, is one of our regular banding cooperators. While I 
        have not had an opportunity to make a careful study of the data re-

        sulting from his operations, it has seemed to me that the birds 
        banded and released at that point migrate and otherwise behave in
a 
        manner that is almost identical to birds raised in the wild. 
 
               I am enclosing herewith a copy of a recent memorandum to Dr.

        Bell on this same topic. 
 
               You may be sure that the project, whether private or under
the 
        guidance of the Wildlife Institute, will have my most sincere 
        interest and if I get any kind of an opportunity to make the trip,
I 
        will be delighted to visit the plant at Delta. Men from my section

        working in Canada make this a regular point of call. 
 
               With cordial regards, I am 
 
                                             Sincerely yours,

                         MORAI1DJM FOR DR. BELL 
 
 
 Re: Bell duck propagation project in Llanitoba. 
 
        Jith reference to the attached correspondence regarding'.the 
 Bell duck propagation project in MJanitoba, I feel that I should go 
 into some little detail, chiefly because in the letter of May 13, 
 1938, from 1r. henry P. Davis, Secretary of the Wildlife Institute, 
 to Prof. Aldo Leopold, of the University of Wisconsin, he states 
 "I am reliably informed that there exists a somewhat difference of

 opinion between Pirnie and Lincoln and this may complicate matters."

 I am not informed concerning any opinion on this subject that may be 
 held by Dr. Pirnie, and to the best of my recollection the subject 
 has never been discussed between us. 
 
        I believe, however, that you are fully informed of my own ideas 
on this ratter as it has been the subject of several memoranda from 
me to you urging that the Bureau take up similar investigations. As 
a matter of fact, I have always felt that I was at least partially 
responsible for Mr. Williams going to the Bear River Refuge in Utah 
far the purpose of making similar studies. You will recall that en 
route to his new station, 1r. Williams visited the Delta project and 
rendered a report thereon. 
 
       Briefly, it has been my belief that Mr. Bell was doing a most 
worth while piece of work and one that merited scientific investigation 
in an effort to find out whether or not artificial or controlled 
propagation of game waterfowl other than lallards and Canada Geese 
might not be successfully undertaken within the natural breeding range 
of the respective species. To me the underscored thought is the crux 
of the whole situation, for reasons that are not apparent. It is, 
however, my belief that the only real successful propagation projects 
that are being conducted with these birds are those of Mr. James Bell 
at Delta, Manitoba, and that of the Flanders Club on Long Island. 
 
       I am attaching hereto some correspondence from the banding 
files that we have had with Mr. Bell and his Superintendent, Mr. Edward 
Ward. In this connection I may add further that Mr. Bell has co- 
operated with us for several years, using our bands on the birds he 
raises and releases. These have yielded data that appear to be in 
every way comparable with similar information resulting from banded 
birds raised in the ,ild. I should like nothinL better than to see 
this project taken over and directed tlhrough the Survey in cooperation 
with the Canadian officials.

          Dear Psrderick 
 
                    Last winter the Wildlife Institute referred to me as
 ar- 
          maa of tkieir '.echxial Oomidttee some  orrosonienoe wlth Mr. Jame*
P. 
          3ell of Minnespolis concerning Institute participation in some
duck 
          studies at Delta, Ranitobs. The first proposal dealt with artificial

          propagation and while the committee was friendly toward Mr. BellIs

          efforts, it did not recommend any financial contribution by the
Institute. 
 
                    Later I learned that Mr. Bell really intended to offer
his 
          property for any kind of research and it courred to we that this
would 
          be a good place to seek a final answer to the whole question of
survival 
          value of artificial versus wild dueks which you opened up four
or five 
          Years a. 
 
                    To make a long story short. Miles Pirnie and one of my
students, 
          Albert Hoohbaum, are now on the ground to organize some research
work 
          directed toward this end. The work is supported by the Institute.

 
                    The purpose of this letter is to bespeak your friendly
interest 
          in the enterprise and to inýgegst theft if you are in the
vicinity of Delta 
          this 3u--u-r, you dro-, in a3d give us the benefit of your advice.
Pirnie 
          will be there only a short time but fochbaum will remain for the
field 
          so asn. I think you will like him, and I know that he would be
enormously 
          pleased by a visit from you. If you do not already know Mr. Bell,
I as 
          ur    ou wo uld like him, t".

                    Dear Aldo: 
 
                                I deeply appreciate your letter of June 9th.
I have 
                    written Pirnie asking him for information concerning
the manner 
                    in which he desired payment of the $1,000 we had made
available* 
                    A copy of the letter went forward to you yesterday. Just
as 
                    soon as he replies to my letter these funds will be forthcoming.

 
                                 I'm delighted to know that Pirnie and Hochbaum
are 
                     on their way to Delta and I am confident that their
work on this 
                     project will warrant the expense on the part of the
Institute. 
 
                                I am writing Hoyes Lloyd as per your suggested
letter. 
                   As soon as I have a reply from him I will send you a copy
of it. 
                     Incidentally, Gardiner Bump is quite enthusiastic over
this 
                     project--you have already received a copy of his letter
to me 
                     of June 7th. This makes four out of five of our Technical
Coamittee 
                     giving this project their approval. We have been unable
to hear 
                     from Dr. Ellis in quite a while. So, we are assuming
that he 
                     is in the field. 
 
                                We deeply appreciate your interest in this
matter 
                     and your maintaining the contact with Mr. Bell, Senator
Walcott 
                     has also written to him informing him of our action
in making 
                     these funds available. 
 
                                In reference to the postcript on your letter
I think 
                    this will be entirely satisfactory insofar as we're concerned,

                    but in view of the fact that I have already written Pirnie
I 
                    would rather wait until I hear from him directly before
sending 
                    him a check. If it becomes necessary for him to have
money 
                    immediately, we can supply it. 
 
                                With kindest regards and every good wish,
I am

Dear Henry: 
 
          Miles Pirnl is here today and he and Albert Rochbaum, who 
is to be the field student at Delta, leave this afternoon to begin work.

 
          Mr. Bll is absent from Minneapolls, but he very thoughtfully 
completed arrangements for the reception of Pirne and Rochbaum at Delta.

They will not be able to stop and see him at Hnineapolis as T had hoped,

but thV hope to see him at Delta in the near future. 
 
          At the present time there appears to be only one possible 
cloud on the horizon, and that is the attitude of the Caneaian authorities.

It appears that Plirle, before he had ny serious idea of Institute 
participation, had asked Hoays Lloyd for scientific permits in oase he 
were able to return to any part of Manitoba for waterfowl studies this 
siner. le has not had a reply. I do not know how to construe this, 
but it certainly adds urgency to my previous r   endation that the 
Institute feel out byes Lloyd on the whole enterprise. I assume yw 
baye not yet done this and I attach a rough draft of a proposed letter to

byes Lloyd. I recommend that you or some other officer of the Institute 
aWres some such letter to Hayss Lloyd as promtly as possible. 
 
          Would it be too much to exect that you or Senator Walcott or 
some other reresentative of the Institute drop in at Delta some time 
this smner?   It would be a great        a  t to the boys on the ground.

                                 Yours sincerely,

P.S. As to the mode of disbursment of the Institute fund: Michigan 
State Colleage designates to Pirnie authority to disburse funds for 
special projects on the Kellogg sanctuary. Pirnie tells me that the 
proposal is for the college to likewise delegate to him the disbursement

of the Institute fund. An acountin   will of course be rendered thr.ugh 
the College to you at the expiration of the summer. Is this satisfactory

to the Institute?

 Dear Henryt 
 
             I am delighted to receive your wire stating that 
 $1,000.00 has been made available for the pplortory work en 
 the Delta projeet In accordanee with my letter and report of 
 My 7. I still feel samewhat disturbed over not hearing fro- 
 Gardiner Buxq and Dr. Ell.is, but I an assminag that if they teok 
 exception to the recommendations of My 7. they wold have let 
 no know by this time, In ether words, I om assing that they 
 are in the fie ld.l 
 
            The paymet should be ude to Dr. Miles D. Pirmie,, 
We. . ZKllogg Bird Sanctuary, Battle Creek, Michigan. I do not 
know the rules of Michigan State College for handling a cooperative 
project-,' bt I on sending a cepy of this letter to Dr. Pirmie with 
the request that he natify you about any additional details which, 
you need to kow. 
 
            As to details of organisati, I think it bet nt 
to specify them too closely, It is already ~undrstood that the 
#1.000 is for Dr. Pirnie's expense to visit the area and for the 
emploinent of student assisttants for the remainder of the field 
season. It is also understeod that this first year's work is 
exploratory and that continuation of the projset will be ro mee ded 
only if an. attractive opporturity for duok nesting studies is feund 
to exist, 
 
            If you need a more fomnal, detailed oooperative agreeset, 
I will draw one, 
 
            I much appreciate the prompt action of the Imstitute 
in   king the funds available, I an sending a copy of this letter

assuming that if tbey took exetion to the r1oee   ation of May 7, 
they would have lot . know b,, this time. In other words, I   m assuming

that they are in the fteId. 
 
          The payment should be m*de to Dr. Miles D. Pirnie, I. K. KelloM

a copy of this letter to Dr. Pirnie with the request that he notify yo 
about any additional details wbieh you need to inow, 
 
          As to details of ergansation, I thik it best not to spesify 
them too closely. It is alresy understood tbht the $1,000 it for Dr. 
Pirnipe's eyuerse to visit the area sad for the employment of studemt 
qssistrnts for the ramaliner of the field season. It In also uderstood 
that this first yeAr's wor is   ploratory and that coxtinuation of the

                       Dear Aldot 
 
                                       Following up your letter of June 3rd,
I 
                      talked to Senator Walcott this morning and he game
me the 
                      green light on proceeding with the James F. Bell Duck

                      Nesting Project at Delta, Manitoba, under the terms
of 
                      your letter of May 19th. 
 
                                       I wired you today as per copy attached.
We 
                      are assuming that either you or Pirnie have your student

                      picked, or know where you can secure him, and this
letter 
                      may act as your authority to proceed with the organization

                      of this project. You are in much better a position
to do 
                      it there at that endj due to your contact with Pirnie
and 
                      Mr. Bell, than we are here. Please advise me of your
plan 
                      of procedure at the earliest possible moment and give
me 
                      the information concerning to whom the check should
be 
                      made, and I'll see that it is put in the works immediately.

 
                                       A waterfowl research project in Canada
is 
                      much needed right now on the part of the Institute
and 
                      even though this work must be continued on a year-to-year

                      basis, I think it is fully warranted in view of your

                      statement. 
 
                                       Ted Doremus is confident that he can
raise 
                      the money to finance this project over a term of years.

                      Will you please put the machinery in motion to get
this 
                      survey under way? 
 
                                       With kindest personal regards and
looking 
                      forward to hearing from you in the very near future,
I am

Dear Henry 
 
          I am mbarrassed to find on w return from the 
field that no votes have been reeived from Gardiner Bum 
or Dr. Xll1s. Stoddard, Hubby and myself have voted 
favorably on the duck nesting project. I have sent a ro- 
ander to Damp and    lis and asked them to send their vote 
directly to you. I suspect, though, that they are both in 
the field and that we may nt be able to get a vote from 
them in the near future. I do not anticipate any objections 
on their part and I am willing to go ahead on the three out 
of five vote if you think it wise. Sorry for the delay. 
 
                            Tours sincerely,

Dear Henry: 
            I am in receipt of a note from Aldo Leopold 
asking that I drop you a ine direct with regard to my 
vote for or against the Institute's finanoing the proposed 
Delta duck nesting project. 
            Please record me as voting emphatically in 
favor of this proposal. I have long felt that the artifi- 
cial quantity production of game birds ha. received so much 
attention that efforts to determine and improve the S 
of the birds produced in terms of their reaction under wild 
field conditions have gone entirely unsupported. In a small 
way, you may remember, -,e have been working on this problem 
with grouse, pheasants and certain ducks, particularly black 
duck and mallards, at our Experimental Game Farm here in 
New York State. Present indications are that the ability 
to satisfactorily revert to the wild and to maintain them- 
selves therelb is largely influenced by a host of small 
items which make up the incubation, the rearing and the 
liberation techniques. The past tendency has been to 
place relatively little emphasis on those practices which 
would encourage survival once the bird is liberated, sine* 
they are apt to out the number of birds raised to liberat- 
able age, which to date has been the criterion of -ucoeess 
in this field. The problem, for instance, of raising mal- 
lards is greatly simplified by keeping them tame and by 
feeding them commercial feeds, but the inevitable result is 
to lose the migratory instinct and to develop a bird that is 
too heavy and too unwary to maintain itself once liberated. 
Likewise, the wilder the bird the smaller the number of eggs 
they are likely to lay in captivity. 
             It is to be hoped that Institute support for 
this much needed but little understood phase of game breeding

will assist-in focusing atteution thereon. 
            Of oourse, too, it mu-t be realized that the 
Delta experiments are in effect out on a scientific iimb, 
much as is our Experimentai fý;me Farm vork, in that, because 
of geoerphioal distribution it is impos lble to tie them 
as olosely to a research center such as is represented by 
most universities, as is desirable. Aldot' suggestion of 
encouraging Canadian researchers to interest themselves in 
this project is,-I believe, one key therefor to future 
sucess at this station. 
 
            Lat*   as this work develops, it might be that 
some of our work in crossing the black ducks with the 
Flanders strain (now fourth generation,) the development of 
what we hope is an exceptional strain of free-flying wild 
mallards, and of a etrain of black duck- that will reproduce 
satisfactorily in captivity, may be tied in as helping to 
round out this field.

Mr. Aldo Leopold,

Madison, Wis. 
 
 
 
Dear Aldo; 
 
       I found your letter copies and the copy of the report on Bell project

at Delta,Manitoba, here upon my return a couple of days ago from a short

field trip. Have gone over this and previous material along this line with
a 
lot of interest* 
 
     As a member of the Institutes Technical Committee, I certainly approve

the proposed appropropriation for exploratory work on a duck nesting study

in the Canadian breeding grounds,and Delta might well be an ideal place.

If the preliminary investigation  looked good, some long time and 
comprehensive studies might follow* 
 
     Am very glad to have the copy of Williams report. ( note that you have

marked many things through this reportwhich may be open to question-they

impress me the same way). 
 
     Am glad that this proposed investigation is not a game farm proposition,

but a study in the wild with the game farm product handy for supplementary

studies. I cannot but feel that it will take a generation or more,with 
a great many game farms and propogators to settle the question of the relative

value of artificially produced birds in restocking the wilds. Certainly this

will be true if quail propagating is in any way paralell. Here we find 
that birds reared by certain methods,and "finished off,* in certain
ways, 
adapt themselves readily to wild conditions and thrive in fair percentages*

The product of another game farm may be reared on wire to maturity, be as

tame as barnyard pets, know noting of food outside of mashes, and almost

entirely fail when released* But the product of one farm sells for as much

or as little as that of the othei. If the product of one game farm be considered

as typical *artificially propagatedO birds,the method might be considered

as successful. If ones experience has been with liberation of birds from
the 
other type of farm,the result can be put down as failure. I presume that
the 
same will prove to be true of waterfowl propagating. 
 
     Personally, I cannot warm up to any method which entails the gathering

of first cluih duck eggs in the wild, for artificial propagation purposes.

If duwks were like quail and layed large second and third sets it might be

different. But such evidence as we have indicates that the second clutch

may usually be very much smaller than the firstwhich leaves the duck with

a small set to inc bate and rear if the first is taken* I would much prefer

at the present stage of the game to leave the wild duck with her larger first

stt* And until the game farms demonstrate that they can produce an abundance

of eggs, ind from them high grade birds for restocking, from second and 
third generation birds, they have not gotten very far. About all that it
proven, 
in my opinion, by the hatching and rearing of wild produced eggs from the

various species, is that they m   be worth further working with.

       It may interest you to know that Mr. Bell is much interested in 
artificial quail propagation on a place that he is interested in in Mississippi,

and that this place bas taken out a Non-Resident membership in our Association*

Komarek has visited his project twicep though I have not seen it yet. He
seems a, 
man greatly interested in attacking thees problems in a scientific manner.

 
     I hope that you and the family are all well, cnd that all goes well
with the 
work. There is small liklihood that I will get up that way this sunmer (have

a week or more work in the Missouri Ozarks for second week in June and later,

but hardly believe I can stretch this into a visit to the Rockford-Madison

section). Surely would like to see you down this way sometime;have a lot
I would 
enjoy showing you and discussing with you. 
 
     Am a poorer archer now than I was three years ago, which is saying a
lot* 
Am away half the time and rushed the rest, so am out of practice badly. But
the 
interest does not failand hope to shoot some during the summer. 
 
     With kind regards to you and yours, I am, 
 
                                     Sincerely yours,

             Dear Aldo: 
 
                   I believe I virtually gave a vote in 
             favor of approving for American Wildlife 
             Institute cooperation, the preliminary 
             research on duck reproduction at Delta. 
             To leave no uncertainty, however, I formally 
             express approval of recommending this 
             project, with the budget as outlined in your 
             letter of May 19 to Mr. Davis. 
 
                  I agree that the project is desirable 
             because of its bearing on management; because 
             it promises to lead to scientific advances; 
             because it may help the development of 
             wildlife research in Canada, and because it 
             will put the Wildlife Institute in a better 
             position. 
 
                                      Cordially,

Dear Idles u 
 
          I an much gratified by the goo ne of MItiigan State 
Qollegets contribting your time this year. That helps a lot. I haes 
now placed the wole mtt*r before the QeCmittee for final 4deelon, 
and I have word from Henry Davis that the financial prospeets are 
encouraging, although the mone is not now in the beak. 
 
          In view of the fact that Hemy Ust find these fuze, I would 
llke to keep this year's amunt low, and for this reason I have taken 
the liberty of not inoluding the extra $500 for an additional studt 
and for a trip by myself. I di innlude $100 for local temporary help. 
After all,, we can only hope to open this thing up this year., and by show-

ing its possibilities, we can expand it to fit. 
 
          While I am frankly admitting that one of the purposes of this 
study is general stimilation of the field, including the work of the 
U.S..B.. in that field, I think we should try from the outset to elist 
their enthusiasm for the job. Wouldn' t it be a good idea for you to 
Invite Lincoln up there sometime during the su-amr to get his advice en 
present and future work? This is just a sugestion and of course should 
await the action of the Institute. It would be a f2iemdly gesture and 
might help geatly later when the time comes for somebo4y to go to 
Washington to analyze the bandIng records which, as you %V, are in 
arrears. 
 
          I have been much heartened by Williams -and Marshall's nesting

paper in the ourrent Journal. It shows that the yeast of new methods 
is beginning to work from the bottom up in the Surve and will put us on 
our mettle in this project. Don't you think their paper is a good one? 
 
          In m judgment it would not be wvie to try to interest the 
nstitute in the duck book at this timt, I thoroughly aee with you 
that such a book is en ed. but to introduce proposals for vablications 
at this stage doen't seem to me Eood strate.      rou San, of course, 
count on Albert's interest in furthering the book project.

  Dear Mr. Leopold: 
 
           On Friday I saw Dean Huston and from him 
 got a tentative 0. K. for absence from the Sanctuary 
 a week in June and for three weeks in August to 
 help in the waterfowl investigations, provided my 
 expenses are met by the Wildlife Institute or others; 
 and they are willing for the College to contribute 
 my time. I shall be anxious to learn the decision; 
 and if necessary, shall try to get funds elsewhere 
 should the Wildlife Institute fail us. Should you 
 learn more about the Ducks Unlimited, (Canada or in 
 U.S., I should like to hear from you in that regard.) 
 
          Might the Institute be interested in 
 beginning work on a duck identification publication? 
 Right now there is a lack of suitable illustrations 
 and text to cover even what is known on the plumages 
 of waterfowl, age and sex differences, etc. As you 
 know, I have hoped that Albert might prove to be the 
 artist who can adapt himself and apply himself to 
 this task; and of course such effort should be 
 rewarded. Such matters as the aid of the Field 
 Museum in preparing skins of record specimens of 
 young ducks of known age can of course wait until 
 there is approval for the project. Rudyerd Boulton 
 was here last night and spoke very highly of the 
 Golden-eye work of Albert's*I have in the office. 
 I am writing today a reply to his (Albert's) letter 
 of May 7. 
 
                    Very sincerely yours,

                   Dear Mr. Leopold: 
 
                              I am really thrilled with the prospects 
                   of teaming up with you and your group, and bringing 
                   whatever tis place and the Michigan State College 
                   have-into the waterfowl researches in Canada or anywhere.

                   To try to stimulte and aid such studies- as weil as 
                   to partcipate-- seems a proper aim; and I hope a good,

                   long-time program may result. As you seem to be willing

                   to do the steering, I am ready for the job as one 
                   oarsman, marsh-wader, or whatever I can do. 
 
                              I am in accord with y~ur outline, and think

                   $1,000. should do for the firs try.   L-t might not be

                   enough to put over a very extensive research program,

                   but- more important, almost-- it should most certainly

                   go a long way toward doing what you list at center of

                   page 2 in your Report on the Delta Waterfowl Project!

                   (Items a to e.) " 
 
                              There is no need at this time to elaborate

                   on the types of waterfowl investigation which might 
                   well be included in the proposed field work at and near

                   the Delta Hatchery at Lake Manitoba. You have listed 
                   enough of the recognized problems and which tie into 
                   Mr. Bell's work. Members of the Manitoba Fish and Game

                   Association end members of the Natural History Society

                   will be very cooperative and helpful, I am confident.

                   (In this connection you may be interested in the enclosed

                   letter from Ralph Fryer, a local naturalist and likely

                   young fellow who might be included in s field crewý

 
                              Enclosed is a tentative, and I think reasonably

                   accurete budget for this summer's work as you have outlined

                   it. Should funds be available, I should very much like

                   to see the crew enlarged to three men on the work- 
                   Albert; Brewer from D1. S. C., and Fryer, perhpps, from

                   Winnip'eg-- in addition to Mr. Bell's staff who I asie

                   would be on the job as usual. .J                     -

Travel expenses, M. D. Pirnie,

Misc. supplies or local labor                  75- 
 
 
 
 
 
Another $500. would be most useful as follows:

          For ali tast to(Hochbaum,) 
             salary and expenses for

                                           $ 500. 
 
 
 
 
Note: Rooms would be available at a duck club nearby, 
and I imagine Bell's man (his name escapes me) would 
take in boarders for one meal a day.  &rsh is not over 
40 miles from good small town, so getting supplies is 
ee sy. 
 
       As to my salary; I shall try for Kellogg or M. S. C. 
aid for the work, also for student fellowships; and do not 
doubt my time would be contributed by the College. At worst 
I would have to have not the equivalent of my own salary 
but encugh to furnish a worker in my place here while 1 
was absent from the State. Shall see the Dean tomorrow 
and write Sat. or Sun. on this point. Expect the Pres. 
here tomorrow and M may get some answer then. Agree 
with you that we dvuld go for expenses only; and hope 
the officials think so also. //

             Dear Aldo: 
 
                              I am particularly interested in your letter
of May 7th 
              concerning the Bell project at Delta, Manitoba. I believe that
this 
              proposition, as it is now presented, offers considerable opportunity

              for the Institute to develop a worthwhile duck restoration
project* 
 
                             I had lunch with Gabe the other day and discussed
this 
             matter with him. He is of the opinion that your suggestion that
this 
             work could ultimately be taken over by the Canadian universities,
the 
             Canadian bureaus, and the Biological Survey is entirely feasible.
I 
             asked him if the obstacle of Government redtape would prevent
his co- 
             operating in this work in Canada, and he assured me that he
did not 
             consider i   such an obstacle insurmountable because he has
had co- 
             operators in Canada right along* 
 
                             I am taking the liberty of sending copies of
your letter 
             to Senator Walcott, C. K. Davis, J. N. Darling, T. E. Doremus,
and Dr. 
             Gabrielson because of their obvious interest, but will not approach

             Hoyes Lloyd on the matter until you have heard from Pirnie.
I sm reliably 
             informed that there exists a somewhat difference of opinion
between Pirnie 
             and Lincoln and this may complicate matters. On the other hand
it may 
             not be of serious moment* 
 
                             I discussed the matter briefly with Jay Darling
when he 
             was here this week and he is very much interested in this project.
It 
             would appear to me that if Mr. Bell is willing to furnish and
operate 
             the plant and the land, the Institute would find the necessary
fands 
             for research--certainly if this phase of the work would cost
only $1,000 
             for this year. 
 
                             I am sending you five copies of a report on
this project 
             which we secured from Gabe and which was made in February of
this year 
             by Cecil 0. Williams, Assistant Biologist. I am sure that other

             members of the Committee will be interested in seeing copies
of this report. 
             I know that Senator Waloott is extremely interested and I hope
that we 
             can work something concrete out of this matter. Many, many thanks
for 
             your splendid cooperation and I am attaching hereto a check
for $20.00 in 
             payment of your expenses in connection with your visit with
Mr. Bell*

      Obserystiona of next it the wild ha  indicatd  m- 
 
oedures to follw in axtifilal prpagation, N)h   wild ducks 
 
begin to lay their  go, the nests are usually net *Weteu ly 
 
fiished until thaev uborf eggs approaches a full clutcsh. Dom 
 
is laoking at the start and hardly  uoh nesting aterial is 
 
present to covr the few eggs. This applies to Abe tosts of 
 
both diving and puddle-wftas, In may instanes the inside bottom* 
 
of the unfiniw d nests ere qite wet sad the ega imprinted with 
 
me** of grasses and rushes upor which the eggs have lain. The 
 
times it takes for these imprints to be amia is aut knowi,, but in- 
 
dications are that the o are not turned for the first few das 
 
at loast, although It in known that the attending femal over 
 
them at Irter1s of an hour or s at a tims   prebably just swfioimt 
 
to keep them viable witheut initiating inoubatioe. 
 
      As the elutch grows larger, the nests are built up with vege- 
 
tation above the wetLess and filled with down. The full olutch size 
 
varies with the different duek species, but at approimstel eight 
 
oes the femles ted the nests mo     regularly. Sines the e*s in 
 
a cluitch batch within a fe hours of each othr, it is evident that 
 
the first laid eggs take oonsi8erbly lesger to hatth than these that 
 
are laid irediately before inrubatio  begins# The atmopheri 
 
eunditioa murronding a wild duck nest se snearly always to he 
 
one of high humidity, eve though the eggs themselves appear to he 
 
dry and glossy. They are undoubtedly wetted whenever the attending 
 
female returns from the water*

      Wheri the ew aivo at the hatchery (a picotur of which is 
 
shoin in Figure a) they are eandled to eliminate the infertile 
 
ones. Wild duck e*gg often give off an unpleasat odor after 
 
several days In the iubtor If they aeo not cleansd first. 
 
They are therefore wiped with a cloth 4mW with lukeum. wtor# 
 
and then dried with another oloth. Results of oxper.ats with 
 
dirty and washed eggs have shown that the washing treastent in 
 
ro way affets the percentage of batch. As a ph*se of andling 
 
the eggs are sorted aseoording to their degree of adano~mant 
 
and then placed In the iubator cmpartme at a temerature 
 
of 99 degroes F,. This tempernture was found to be the optiumn 
 
settin, for rumiAg of the iLnubator In order to afford the 
 
highest peroet hatch, mad to work equally wonl for the incubation 
 
of egg of the folleoing dusk speolost seavoasbk   redhead,. lesser

      The operation of the incubator is perhaps the vast vital

      As soon as the eggs haw vbe~   wanmd to ineabating toeratures, 
 
they are sprayed with distilled water from an atomizer* This is

Dear KeMryf 
 
          I had a Aepas-nt tn Interestin visit with Mr. Bell yesterday 
and I attach a prelimnary report for your Information. I will dd fiscal 
esticotes after T have hoard from Miles Pirnie. A   ia oe ntative gess, 
however. I think the cost for this year would 'be uder $1000. 
 
          I am not posted as to vhther the Institte has or can get su 
a SUM, Neither have I   y information as to th. fiscal relationships 
with Mr. Be11, exept the general principle outlined by himt that he will

furnish and opeate the plant and the land if the Institute will do the 
rbeearch.  I take it, however, that you and S tor Walcott would ot  
so actively Interested in the case if there were not at leost a hop. of 
fnds. 
 
          Thes reprt should, of course, be pased on by the Coittee 
before being acted on by the Institte. It can be sent to thoe Comitim 
as soon as I have the fiscal esticatet from Pirbie. Will you let me kno 
1w)letlhr you are submitting it to the Committee or whether you want me to?

 
          I think the ultimate ob~jectivip should be to develop a line of

 work which can be taken over by the Canedima universities, the Osmedia~n

 bureaus.,n  the V,.S..S. T tiake It them Qatrf,4ans should be consulted

 before the InstItute makes vq final moe sad I earssm Bqoeo Lloyd's 
 department woul1d be the one best able to speak for the Canadians. May I

 leave It to you or Secator Walcott to take the matter up with the proper

 Oana~ian auithorities? Mr. Be11 told me that Royens Lloyd wne Anuious to

 sew him take on some saeteutific guidance and that the l~ack of this guldanee

 constituted his only doubt about the D~elta operation. I infer. therefore,

 that the work would b ecomne by the Canadians. 
 
          1here ma be a residual question as to whether the Delta 
 property ise theý best possible bese for Canadian bre*4Ain studies.
The 
 heaviest b~reedlug belt apparently lies to the nrth. Rowover, there would

 be quiAte a-,n Advantqen in a definite fiscal bae. and none other is available

 or in prospect, and Pirni seemed to have no doubts as to Its suitability.

 If there be an weak point here, It will doubtless appeatr before aW long-

 time ooinoitm~ats need by made. You will note that I hnve phrased the 
 report as the tryout of an idea rather tha~n as the ultimnat adoption of

 0)10.

          I went to Minneapolis yesterday  ad had a very interstig 
conference with Mr. Be1. I am submitting today a report to the Institute,

copy of whiah is attached. Before going further with this, I w-id like 
to be sure, first, whether the gvneral ides" embodied in the report
mee 
with your approval; seconly, I would apreciate your sending me reo 
mendations for this year's cost estimates. 
 
         The first item in these costs ts your own trip, anM I would 
recommend that you spend at least a month there if you can. Albert tell*

me that you are tied up in summer school. Wuld it be possible for you 
to go up there twice, once before and once after summer school? In any 
event, give yo uour figure for such time as you can spare up to a nonth,

and make It clear whether your figure ti inclusive of travel ex    e. I 
would suest that the simplest set-up in beth your ease and that of the 
student would be a lup sum, you to travel yourself up and back. Mr. Be1 
did not make it clear what the local facilities for board and lodging are

and I hesitated to inquire about such details. If you know anything, 
however, you might tell me, since the question obviously bears on rates of

 
 
          The second item of eopese  would be the graduate student. 
Assuming that y   went Albert HRchbaum, he could be up there this year from

June to October inclusive, which would be five months. If he pays his owM

travel to and fro and furnishes his own car, board and lodging, it would

take a little over $100 per month to yield the same not earings as the 
Park Service pays for summer students, namely $70 per month. I understand

these smmer students are furnished board and of course they do not have 
to have a oar. Shall I ask for $100 per month or do you think a slightly

higher rate necessary? Nxt year Albert could spend the entire suemer 
from April to October on the ground. 
 
          If you feel like it, I would also like to have your corrections

or adAitions to the research appendix attached to the report. I pulled 
this out of thin air simply to give the Institute some realistic idea of

the kind of work to be done. 
 
          You said something while here to the effect that Mr. Kellog 
might be willing to stake you to a Canadian trip. It occurs to me that 
the work up there might be an extension to the Kellogg Sanctuary and to 
Michigan State College b7 reason of the research data it will yield for 
ultimate publications and for current teaching. Possibly them either Mr.

 
  

					
				
				
 
 
 
 
2 - Mil" D. Pirate 
 
 
Kellog or the State Ocllege could furnish al or part of your salay, 
the Institute contribution taking the form of an additional honorarium 
to cover expense, personal trouble, oto. I am, of course, not trying to 
lay down your fiscal policy, 'ut mircly to sugget variouv ways in which 
the fiscal apsects might be handled. If there is to be an contribution 
thro     alary or otherwise from Mr. Kellogg or the State College, please

inform me fully, 
 
          I would like to see this thing develop a kind of team work 
between your graup an mine. At a later date, when policy questions have 
somehat crystalliSed, I migt want to ask the Institute or somebody for 
a trip up there yself. 'hat I visualise and look forward to is a combin-

ation of your tenical knowledge of waterfowl and my experiee in the 
pelicy field. 1 oan also see at a later date active oooperation by 
$ysiologiets, geneticists, eto., to be hand-picked from both Institutions

and possibly the Canadian institutions. I think the ultimate object 
should be for the Canadian institutions to take over the Job, but I gther

from Mr. Bell that the University of Manitoba is hardly yet in a Position

to do this. I hope you oan stop over here either on your way up or on 
you~r Wy back, 
          If there is an part of this letter that is out of harmony with

your own views and hopes, be sure to let me know. Please also lot it be 
clear that I am not trying to write the ticket. I am merely giving you

. Mr. James 1. Boll of Minneapolis last year offered the Institute 
 
the use of his land and propaeation plant at Delta, Manitoba, for research

 
work in artificial propagation of waterfowl. 
 
     The proposal was act recommended by the TeOhnial Committee, ea the 
 
grounds that the baning returns from artificialIy propagated waterfowl 
 
were not sufficiently eAnooraging to make them of prospective value in 
 
maintaining the supply. The question was considered wholly in terms of 
 
improvemnt in propagation by means of artificial light. 
 
 
N   F2!oja*    It now develops that Mr. Bell Is not interested exclusively

 
or even mainly in artificial propagation. What he desires is to offer his

 
plant and his property for aw  research useful to waterfowl conservation.

 
gie will carry the plant and the land. 
 
 
R    re I     A. As has been frequently pointed out by members of the 
 
Technical Comittee, waterfowl research has lagged far behind upland game,

 
whereas the r-speotive urgency is in reverse order. The recent work of 
 
the Biologtcal Surv   on the breeding grounds shows improved vitality, but

 
only along three linels 
 
          i. Geralised banding 
          2. Predation studies 
          3. Yood habits and food plants.

     The present units are doing no considerable amount of waterfowl work,

 
and only a few are located to do any broeding-ground research. 
 
     There remain almost untouched a manber of urgently needed kinds of

          6. Final determination of the survival value of artificial 
             birds vs. wild birds. 
 
     In general, the Biological Survey research in waterfowl in not as 
 
closely in touch with related sciences as it should be. 
 
     In v opinion the initiation of some breeding ground work of a sort 
 
which, for brevity, I will call the 'new kind" would tend tot 
 
          (a) Stimulate official bureaus in both the U.S. and Canada. 
 
          (b) Induct the Canadian universities into the problem, so 
              they can ultimately take the lead in solving it. 
 
           (a) Steer U.S. and other funds for breeding ground improvement

              into good channels. 
 
           (d) Crystallise the enthusiastic Canadian conservation movement

               into good channels. 
 
           (e) Open the way for ultimate research oontributions by 
               scientific foundations. 
 
     In my opinion the Delta property holds out great promise as a location

 
for needed studies, and as a suitable field-base for others. 
 
 
How  o S     . The Canadian institutions so far active in wildlife research

 
are not near Delta. 
 
     The American institution most copsetent to *sit up the waterfowl problem

 
 is Michigan State College (Dr. Miles D. Pirnie). 
 
     I reconmend to the Technical Comittee, and if they approve, to the 
 
 Institute, that:

_rvivaao                   i              A good nmber of banding 
 
returns on nrtificial depwaters raised at Delta hnve come in, but thq 
 
are virtually all from b    o  t  y.     There is as yot no evidence 
 
of whether or where the artificial releases breed. Moreover, birds of the

 
year means birds from wild egs floods having so far destroyed t o  estings

 
of artificial birds which would have yielded second-generation artificials.

 
One obvious thing to be done at Delta is, therefore, the continuation of

 
Mr. Bell's releases of artificial deepwaters (including second-generation

 
or truly artificial birds). fhese should be matched against equal numbers

 
of wild trappings, and the two systematically compared not only for survival,

 
but for breeding dispersal, migration routes, physical development, sox 
ratio, etc.  (The present Delta tahaanback w      j t    wild ones of 
 
 
like age at time of release.) 
 
     Another experiment whieh Is badly needed especially for mallards is

 
to match good and *mongrel* artificials against each other, and against wild

 
trappingg, for comparative survival and behavior. The Institute has a 
 
chance to carry to a final showdown the value of artificial propagation as
a 
 
means of replenishing the flights. This need nt all be done at Delta. 
 
Mongrel releases are obtainable at mW spots. 
 
     The present prospect is that survival i* a umtter of           F Past

 
exneriments such as Lincoln's have not taken qaullty into aooount. Pen wild

 
cnvasbacks vary greatly in weight and perhaps quality. 
 
     Ultimately standards of quality will have to take into account the 
 
development of instincts as well as physique. This is clearly foreshadowed

 
by Long's work (unpublished) at Michigan. Long has found "wild"
turkes

Netn    Studie an   .rsagM~~lj, The need. for wild nesting studies 
of the standard type is too obvious to need coent. 
 
     There are fundamental aspects of nesting, not so far studied at all,

 
which need to be opened up. 
 
     Mr. Uell says caiwLsbacks do not nest until two years old. This may

 
be trae of other depwaters. Simultaneous stady of artificial and wild 
 
birds is the obvious way to get at these b               of our *raw material.*

 
Deferred maturity makes an enormous iffeorene in "broding potential,"
and 
 
this m   account for the relative severity of the effects of drouth and over-

 
shooting on deepwaters. 
 
     Phyiologists now doet"t two kinds of breeding cycle in birds, the

 
'determinate clutch" and *Indeterminate clutch.* Our waterfowl secies
are 
 
not y"et classified In this respect. Reneeting and egg-lifting depends
on It. 
 
Theonly my to d.elop the subject is by experimental manipulation (with false

 
egg) of both wild and artificial nestings. Delta is an obvious place for
' 
 
such work because It requires repeted annual experiments on the same ground.

 
     Qanvasbacks at Delta have been seen this year In a collective mating

 
display analoeous to the booming of prairie chickens. Sine these displays

 
are now recGnised. as no mere ornitkologicl oddity, but as an esst 
 
s        to endocrine chawns preparatory to breeding, It is likely that 
 
discoveries important to breeding-grouad management migt result from mere

 
continuous ornithological observation of a breoding ground like Delta. 
 
 
C              zngtIatM. The excellent pothole study by Turness in the current

 
number of the Wilson Bulletin is a good Indicator of the readiness of the

laek of research funds to an extent hardly credible to those familiar with

 
the generously financed #9 unite.0 The sere existence of a visi'ble ad

Dear Henrys 
 
           I think I made a mistake in the Bell case. I think we 
were right in expreesing lack of financial interest in the arti- 
ficial propagation of ducks, but Pirnie thinks, and I agree with 
him, that Bell's place would make an extremely valuable headquarters 
for banding and other experimental work which is so badly needed in 
the duck breeding belt. I have been corresponding some more with 
Mr. Bell and find that he, too, is interested In this, and I am 
offering to run up to Minneapolis to see him about it. I hope this 
meets with your approval. Do not be surprieed if you hear from me 
further about the Bell case. 
 
          What I visualize Is an experimental station where his pre- 
existing game farmer does the game farming work if he wants to con- 
tinue it, but where a new spries of banding and other duck experiments 
are to be initiated, supervised in detail by Pirnie, and in a general 
way by myself. Pirnie brings me glowing aoccrnts of the cooperative- 
ness of the Canadians, and I think much local help can be obtained. 
Anyhow I think it is worth going to see ell about. 
 
          I have no travel funds. Would it be within reason for the 
Institute to carry thie trip? If not, I of course will gladly do it 
persomnlly. 
                                  Yours sincerely,

    Dr. Aldo Leopold, 
    1552 University Avenue, 
    Madison, Wisconsin. 
 
    Dear Dr. Leopold: 
 
    Thank you for your very interesting letter of the 
    thirteenth. 
 
    I am pleased to learn that subsequent developments 
    have shown that the banded returns from artificially 
    raised ducks are satisfactory when the ducks liber- 
    ated are in proper condition. 
 
    As I told you, my experience has been largely with 
    the diving birds, because at the time I undertook 
    this experiment very little, if anything, had been 
    done with them. The mallards are quite another 
    proposition. 
 
    While I don't share your opinion about artificial 
    game production, provided it can be made a more or 
    less continuous process, nevertheless I appreciate 
    that it is rather a long shot from the standpoint 
    of operating costs. However, as I follow the re- 
    sults of the various shooting clubs which now 
    raise and liberate birds for shooting, I am in- 
    clined to believe that if the cost could be reduced 
    from the present basis more attempts of this charac- 
    ter would be made and there would be some lessening 
    of the pressure against the migratory stock. 
 
    Now, as to the possibilities of the Canadian plant 
    along the lines you have suggested, we have almost 
    unlimited opportunity for trapping and banding 
    wild birds, and we are also undertaking, with the 
    Department of Biology, some experiments with the 
    homing instinct of birds. This year they are 
    shipping me a number of newly hatched birds to 
    be raised, banded, and liberated, and they are 
    also sending me several hundreds of eggs from the 
    same lot, to see at what point this homing instinct 
    is developed. 
 
    You suggest that I resubmit the case, with only 
    incidental emphasis on light manipulation and 
 
  

					
				
				
 
2. 
 
 
with primary emphasis on the comparison of survival 
of wild and artificial birds of as many species as 
possible through a term of years. 
I am distinctly interested in what you tell me 
about your own thoughts in the matter and the 
qualifications of Mr. Hawkins. 
 
I am off East again Sunday night for some ten days 
or two weeks. On my return I should be very glad 
if you would suggest some means of our getting to- 
gether for a personal talk. 
As to the matter of expense, I shall be very glad 
to undertake any of this in connection with these 
preliminary con siderations. 
 
                           Sincerely yours,

      Dear Dr. Leopold: 
 
      I have been away and I am therefore tardy 
      in answering your letter of March fifth. 
      I quite understand your position with re- 
      spect to the attitude of the committee and 
      I will not bother you further. 
 
      I am very much interested in the next to 
      the last paragraph of your letter, in which 
      you say you are at a loss to understand why 
      artificial releases do not survive. We have 
      not had this unfortunate experience. Our 
      returns have been equal in percentage to 
      those of trapped and banded wild birds. 
      Maybe this is because of the age and condi- 
      tions under which we release them. We have 
      yet to receive a report that a bird was not 
      in excellent condition. 
 
      If there is any literature on the non- 
      survival of artificial releases I would 
      like to have it. 
 
      Thanking you for your consideration, I remain 
 
 
                               Sincerely yours,

Dear Mr. Be~lls 
 
          I would be much interested to see your place, bt I am afraid 
the question of an Institute contribution ts settled in the negative, 
at least as far as the Technial Comittee is concerned. 
 
          We found ourselves in unanimus agreement on this pointt that 
the returns from all artificially propagated ducs (i.e. bans from 
birds released to the flight) are so far so discouraging, as aompared with

returns from wild-banded ducklings, as to cast doubt on the value of 
artificial releases as a means of buiilding up the flight. 
 
          It is the emttee's belief that the stimlatioun of egg pro- 
duction of ligt would be an interesting experimeont, but even if sucessful

would hold out little hope of practical value as a weans of agenting the

crop because the artificial birds do not survive. 
 
          Incidentally the committee believed, as you do, that egg pro- 
duotion c. h built u    b  lightin,. It has bon done on to many speeies 
as to leave little doubt of success. 
 
          Just i   artificial releases do not survive is still a total 
witery. When we get light on this we might possibly see your proposal 
in a different light. 
 
          The comittee is sorry to have to write you unfavorably, but 
the call on Institute funds is so great that we cannot Justif research 
the outcome of which Is not clearly of ultimate utility to conservation.

 
          Thanking you for your interest, 
 
                                    Yours sincerely,

   Dear Dr. Leopold: 
 
   I have had several telephone conversations re- 
   cently with our mutual friend Senator Walcott. 
   Indeed, I conversed with him last night and 
   among other things he told me of the meeting in 
   Baltimore and of his satisfaction in the pro- 
   ceedings. 
 
   He said also that he had talked with you about 
   our proposition in Canada and that you had ex- 
   pressed a desire to see the place and familiarize 
   yourself more with conditions and what we have. 
   I hope this can be arranged. I shall be very 
   glad to consider going up there with you when 
   the season is sufficiently advanced so that we 
   can have the most favorable circumstances. 
 
   I wonder if you are at all familiar with the 
   work that William Rowan has been doing at the 
   University of Alberta. I think he is a real 
   genius and that he is doing some very constructive 
   research work. 
 
   Trusting I may hear from you at your convenience,

         My dear Aldo: 
 
                   I anm delighted to get your letter and the 
         four pamphlets, "Farm Game MJanagement in Silesia," 
         "Naturschutz in Germany," "Notes on Geme Administra-

         tion in Germany," and "Deer and Dpuervald in Germany."

         I shell reed all of these with the greatest interest. 
 
                   You are doing marvelous work In the field 
         of ne+tural history and suoDlying the backbone of our 
         own progrem, which is going to be the real progrrm for 
         the BloloIcal Survey to follow before we are through 
         with it. We have an outstanding committee, and it is 
         refreshing to hear them telk. 
 
                   I cannot help but agree with your findings 
         with reference to the tell oroposition. There is no 
         risarticular justification for attempting the artificial 
         reproduction of wild ducks, particulprly the deep-water 
         or diving ducks. I hive raised them end have gotten 
         them to breed in captivity, canvasbacks, redheads and 
         broadbills. It is terribly artificial, however, end 
         even though it cen be done as a stunt, Ps it is done 
         by Hugh Wormold of Norfolk, England, the birds do not 
         compare with the birds repred In the wild state under 
         natural conditions.

  Dear Professor Leopold: 
 
  Former Senator F. E. Walcott has been interested in 
  some experimental breeding experiments which I have 
  been carrying out in connection with wild ducks at 
  Delta, Manitoba. He has taken this matter up with 
  Mr. Henry P. Davis of the American Wildlife Insti- 
  tute with the thought that the Institute may become 
  interested in joining with me in these experiments. 
 
  Mr. Davis has asked me to sit with the Technical 
  Committee between the fourteenth and seventeenth of 
  February but my engagements will not permit this. 
  He suggests that if it is impossible I get in touch 
  with you. I am wondering if you have in contempla- 
  tion a trip to Minneapolis at any time between now 
  and then as I would like very much to have the 
  pleasure of meeting you and going over this subject 
  in detail.

                                        We have asked him for a detailed

Mr. Henry P. Davis, Secretary 
American Wildlife Institute 
Investment Building 
Washington, D. C. 
 
Dear Mr. Davis: 
 
The Senator wrote me that there might be a chance of our running across each

other when I was in New York but as I didn't hear from you I assumed that

another engagement prevented you from coming. 
 
As to thd Delta project, possibly a brief review of the history of this enter-

prise will prove informative. 
 
When I first took the place it was overrun with all kinds of vermin and with

cattle. The first thing I did was to get rid of the crows; 864 of them in

one year. The next was to prevent the cattle from coming over the property

and trampling down the nests. 
 
Then came the thought that I should put back in the air as many or more birds
than 
I killed during the open season. In this we followed the easiest way, with

mallards, wintering them and giving them ample protection during the nesting

season. The next step was to stimulate the number of eggs laid by actually

robbing nests and incubating the eggs. 
 
My interest, however, was in the diving birds and we graduated from the mallards

into an attempt at the artificial raising of canvas, redheads, bluebills;
in fact, 
with effort on every variety of duck that frequents our marsh, and we were

successful in doing a scientific job of robbing the nests of wild birds and

incubating the eggs artificially. Our percentage of hatching was high and,
ex- 
cept for one or two misfortunes, we came through with a large percentage
of mature 
birds. As a matter of fact, we found our five-week old hand-raised birds
when 
released almost twice the size of those born in the natural environment.

 
From the captive birds we have secured eggs from canvas, redheads, and bluebills.

It took some time to get the canvas to lay and we were unfortunate in two

instances in storms which drove the birds off and chilled the eggs. In the

case of the redheads and bluebills we have succeeded very well. 
 
About this time I became interested in the work that William Rowan was doing
and 
we tried to stimulate production with the use of artificial lights, including

ultra violet. This worked very well with the mallards but I didn't have the

scientific supervision necessary to carry on the experiments. 
 
The objective at the present time is to duplicate the environmental changes
which 
a bird goes through in migration and return and to see if we can not increase

the cycle two or three times a year, with breeding in each cycle. This will
re- 
quire work in hormones, with artificial stimulation with both light and tempera-

ture And also with feeding. To do this we must engage a scientific staff
and 
establish a laboratory. I have a man in mind who has finished his doctor's
degree 
at McGill. I can furnish the necessary housing sad laboratory equipment but

I suggested the amount of four thousand to Senator Walcott and should have

told him that I would join equally in this experiment. Personally, I believe

that we can do it for less but one must provide against contingencies.  I

think the work is well worth while and I would like to we it carried on if

we can secure the necessary financial assistance in doing so.

        Dear Dr. Leopold: 
 
 
        Thank you for the copy of your letter to 
        Pirnie. I apologize for not having acknowledged 
        your brief of the co-operative agreement for 
        the Delta Station, but I assumed I would 
        hear from Palmer. 
 
        As a matter of fact, a letter from him just 
        comes in, which speaks of some further delay. 
        However, anything you work out is entirely 
        agreeable, and when the Foundation is ready 
        to act, you will find me responsive. 
 
        It was unfortunate that I was away when you 
        and Hochbaum were here. You apparently have 
        stirred up great interest in the Delta project, 
        as is evidenced by the various museums and 
        colleges which propose to participate. I am 
        afraid you are far too modest when you say 
        this all comes up spontaneously. 
 
        Give my best to Hochbaum and Joan and extend 
        to them and accept for yourself my very best 
        wishes in the N~ew Year. 
 
 
You:

Dear Aldot 
 
 
                I am attaching hereto our check in 
the amount of $441.56 to cover Hoohbaum's salary 
for this coming month and his expenses while at 
Delta. 
 
                So far we are over our share of the 
Delta budget but I am hoping that we'll be able 
to get the thousand from Bell to even us up. 
 
               Ybe're having a meeting of our Executive 
Cormittee next week on Wednesday and I hope some 
definite action with regard to contacting Mr. Bell 
will be undertaken. 
 
               7i1th best regards, I am 
 
                                      Sincere,

Dear Morti 
 
          The budget for Delta tet up $400 for Hochbasutus 
epeases and $200 for travel expenses for Pirnie and wysalf. 
I afterward found that I had failed to take account of Peter 
Ward, and I charged his salary from April to November($240) 
against these expense ftnds. 
 
          Attached is Hochbamems expense account in the anmot 
of $291.56. Since it has never been clear how we were financed 
at Delta, I am unable to make a flat recommaedation for Hoohbauu'e 
reimbursement in this amount, but hope that enoug balance remains 
to take *are of the aocount. I will leave the matter in your 
hads.

                   Dear Aldos 
 
                                  I have a copy of your letter of November
29th 
                   to Miles Pirnie. 
 
                                  We had a very hurried meeting of the Executive

                   Committee on November 10th, the day before Senator Walcott

                   sailed for Europe. This meeting was called specifically
to 
                   consider the Conference and affairs of the Federation.
Little 
                   else was undertaken. 
 
                                  I tried to get some action on the Delta
project 
                   but nothing definite was done. Since that time I have
written 
                   to Mr. F. B. Davis, Jr., who, as you knowv, is our vice

                   president, and who is well acquainted with Mr. Bell. At
the 
                   meeting during the brief time we discussed the Delta project,

                   Mr. Davis suggested a counter proposal to Mr. Bell. As
the 
                   matter was left pretty much in the air, I wrote Mr. Davis

                   giving all the information I had, a copy of your correspondence,

                   the agreement, program and budget, and asked that he contact

                   Mr. Bell with the proposal he made at that meeting. 
 
                                  I have not yet heard from Mr. Davis but
as soon 
                   as I hear anything definite from him I will advise you.
I 
                   certainly hope we can get something done on this project

                   pretty soon. Everyone is extremely interested in the work

                   and eager to see it progress. They favor the taking over
of 
                   the hatchery and Mr. Bell's proposal but it has been very
hard 
                   to get any specific action. 
 
                                  We will have another meeting after the
first of 
                   the year and I hope that we can get the thing settled
at that 
                   time.

Dear Dr. Leopold: 
 
 
      Mr. Main changed his plans and has gone out to 
the Pacific coast in connection with Ducks Unlimited 
work. This is the reason he did not call on you last 
Thurday as I had led you to believe he would. He 
still intends to have a short holiday in the south 
after Tanuary 1, and will, no doubt, advise you later 
when he will be passing through Madison. 
 
      Your note and the reprints of Al's paper were 
received yesterday and, as I am leaving for the coast 
myself to-day, I will take one along for Mr. Main to 
read. Al. is certainly doing splendid work at Delta 
and the information is of practical importance in 
management. rseewvs . 
 
      With kind regards, I am, 
 
                            Yours very truly,

Dear Miles: 
 
          I have not heard from you or Mort Palmer or Mr. Bell 
about the rough draft of the cooperative agreement for the Delta 
station. I have, however, just received word from Dean 
Christensen that should the other parties be agreeable to such 
a set-up, he heartily approves the venture. I had anticipated 
some possible difficulty because the agreement does not provide 
for handling the funds through the University. This, I fear, 
would not work because of the local expenses for local help. 
Before pushing the matter further though, I would like to be 
sure that the rough draft conforms in general with your own 
picture of the future of Delta. 
 
          I am sending you half a dozen advance copies of Albert's 
news letter. You will remember approving this proposal while we 
were at Delta last summer. 
 
          I am sending a copy of this letter to Mr. Bell for his 
information and also to Mort Palmer of the Institute. 
 
                                   Sincerely yours,

                         the amount of $60.00 v4hich is required to complete

                         our obligations as of December 31st. 
 
                                     We had a brief meeting of the Executive

                         Committee in New York last week. It was called in

                         pretty much of a hurry to consider plans for the

                         Conference, Wildlife Week, and the stamp sale. 
                         Little else was accomplished as Senator Walcott

                         was leaving the next day for Europe. 
 
                                     We are planning another meeting shortly

                         after the first of the year but in the meantime
I 
                         am trying to get some action through Mr. F. B. Davis,

                         Jr. in connection with the Delta project. He has

                         suggested a counter-proposal to Mr. Bell and, in

                         view of the fact that they are good friends, I have

                         asked him to approach Mr. Bell on the subject. I

                         hope we will yet be able to see this matter 
                         settled. 
 
                                    With best regards, I am 
                                                           Sincerely,

               My dear Aldo: 
 
                      Herewith I am returning the cooperative agreement 
               covering the Delta Duck Station which you left with me 
               Friday afternoon. 
 
                      I have read the agreement and have shown it to 
               Dean Christensen. Both of us agree that it is a very 
               desirable project, and are of the opinion that the methods

               of administration which are provided in the cooperative 
               agreement should meet the needs. We have no suggestions 
               for change in the agreement, and are glad to give our ap-

               proval to your participation in the stud~y to the extent 
               indicated in the agreement. 
 
                                            Sincerely yours,

Dear Professor Leopold: 
 
 
        I had not thought of the newg 1pttor as anything 
more than a note for our own bunch and 100 copies will be 
more than plenty.   I do not want to burden you with Delta 
chores and can send them out from here if Vivian will send 
them up. On second thought, though, time is so short before 
leaving that it might be better to hold them and I will 
take care of them when I get back. 
 
       I will be bringing some specimens across and in order 
to get over the line with out delay will you kindly send a 
letter to the Collector of Customs a! Noyes, Minn. This should 
merely yate that I am an American citizen working with the 
University and that the sp-cimens I carry are to become a 
part of the Collection of the University of Wisconsin. I had 
some difficulty last year but was told this spring that such 
a letter will be enough. You may be sure this will be greatly 
appreciated. 
       It is my plan to leave Delta. November 29 and be in 
Mfmm St. Paul for the meetings on Vec.1 and 2. Swanson has 
asked me to give something on the Delta wotk under the title: 
Delta. Duck Studies, 1939,. If you agree, I think I shall 
confine my topic largely to the bag tally considering, 
particularly the relationship of the different types of shooting 
to the sex ratio of the bag. By the way, It was very much 
interested in your note on the jump shooting at La Crosse. It 
looks as though the heavy kill. in females in jump shooting 
is not confined to the breeding marshes. 
 
        Art writes that he is having good results with the 
cloacal character and that he is using it on trapped birds too. 
I have made a last check-up on the captive birds and there is 
no sign of any important changes in the characters. Wish we had 
a place to keep birds at Madisonfor we should follow this 
through the winter. 
        The fisherment started to fish a few days too early 
this year and many were nearly wiped out with the first south 
wind. 
         Looking foreward to seeing you soon, 
 
 
Sincerely,

Dear Aldos 
 
                Thank you very much for your letter 
of the loth telling us the amount needed for the 
October payroll on the Delta project, which is 
$160.00. 
 
                 Since the enclosed check was made 
up before your letter was received we are sending 
you $280.00 instead. The difference, of course, is 
to be applied on the November payroll. 
                 I would appreciate your letting u s 
know the total amount needed for November. 
 
                With best regards, I am

Dear Professor "eopold: 
 
 
       I am afraid that I have been a bit lax in answering 
some of your notes in October.   We don't know how to thank you 
for thinking of us on your trip to the south-west. The colleeting 
of thing8 from the Navo#o country has been one of my eerliest 
hobbies and something which you have chosen In your own 
country means more to me than I can say. 
       We hope that you will be able to stay at Delta for 
a longer visit next year and that some of the family can 
come up aeme time.   I hope too that you will be able to make 
a fall visit to Clandeboye. I visited the east side of the 
bay last week and it is wilder than our part of the marsh. 
 
       The bag tally has been pretty much of an all-day affair 
since the season started, but now with ice I am having a chance 
do do some of the things which must be finished before coming 
down. Swanson wanted me to stop over in Minneapolis to give 
a class lecture or a seminar. I wonder if it would be 
prolonging things too long, however, if T remained here until 
the end of the month in order that I might take in the 
Minnesota conference on the way down. It comes such a short 
time after I would get back and would save the trip right back 
up again. 
 
       I know that it may seem pointless to remain up here so 
long, but I think I should stay until the ducks go at least 
and there seem to be an endless number of chores to be 
finished up. 
       The cloacal character is still holding up %l&& at this 
date and I am anxious to here from Arthur of any changes during 
the latter part of his season. I wondered, too, if anything 
has been done along this line by the poultry people. The 
poultry expert at the Manitoba Experiment Station had not been 
fam~llar with the Oharacter. I should think that the ground 
work for investigating this in gallinaceous birds could begin 
with domestic ehickens. 
 
       The marsh has been forzen over for over a week and yet 
ducks are remaining in large numbers on the lake. There are few 
birds being shot, however, exceot on the stubble. 
 
       Gave a discussion of the Delta work for the Winnipeg 
natural History Society earlier in the week. They are a 
live bunch and are foll&wing the work at Delta with a great 
deal of interest. 
 
                           Yours sincerely,

My dear Mr. Hochbaums 
 
           Ia reading over some of the literature of our 
organization, I note that you and Mr. B. W. Oartwright flew 
approximately 2,000 miles over some of our great duck breeding 
grounds, and I am writing to ask what your impressions were 
of the conservation work that can be done in Canada.   We in 
this country realize that it is a vast territory and we are 
keen to have the opinion of a man not in our organization who 
has had a chance to see things at first hand. 
 
           I have had a number of very interesting talks with 
Ted Doremus of Wilmington, and understand that you are doing a 
splendid piece of work at Delta. 
 
 
With best regards, and hoping to hear from you, I

Dear Profetor Leopold: 
 
       Your draft of the budget had not reached me when 
I sent the first note concerning the hatchery costs nor had 
Ward had a chance to go over his accounts thoroughly at that 
time. I hope that my further account of hatchery costs did 
not make things more complicated. 
        The costs in 1938 for hatching and rearing 800 birds 
and carrying the hatchery through the year were as follows: 
 
        Supplies ------------------------#541.80 
             (coal, feed,hay,gas etc.) 
        Wards salary for four months 
              a $125     ---------------- $500.00 
        Assistant for Six months 
              S$75- ---    ------------- $450.00 
         Total cost    1---------------    491.00 
 
         Mr. Wards salary was included because he must 
hire outside help during the hatchery season to take his 
place with the estate. 
        The advisability of appointing a superintendent for 
but six months may te questionedbut the suggestion comes 
from Ward who will continue to take care of the hatchery 
during the winter months. It would be another matter, of course, 
if we were to bring someone from the outside to run the 
hatcherybut as I have understood the matter,it was to 
be turned over to Peter this year. The aid of an assistant 
will be necessary during May and June when the incubstors 
are going. As such the costs of running the hatchery would be: 
 
         Superintendent   ----------------- $600.00 
                   six months @ $100 
         Assistant 
                   Two months o  $75 --------$150.00 
 
         Supplies -------------------$550.00 
 
 
ol------$1200.00

       The cloacal character is still holding up %I00 
and I am anxious to learn how Arthur is finding it. 
 
       The enclosed was prepared at the request of Ducks 
Unlimited and in view of the short time in which I had 
to prepare it and our policy of cooperation with Ducks 
Unlimited, "let it go without calling it to your attention.

Dear Albetiu 
 
          Tour note on hatchery costs atte-hed to the news letter 
still has me gessin. You give $1,500 as the total cost for the 
year an  $200 per month as the cost for wages. presumably of tporar7 
labor from Maq   to July 1. You do not tell .e, thoiai, theu.mn 
thine I nees to know, namely *mt is the~sezlong salary of the 
hatchery r-perintendent. I know, of course, that at present this is 
fused with the car. of the grurs, but uner the imw set-up what 
should it be?  If you will fill in the blank lines in the buet, 
it will all be perfectly clear. 
 
                                Sincerely yours,

       I wtintpd t"o queistion Mr. C'rti~rir-rt befrore' answrerinp

your note rrdin     the letter to thn Unkiversity of ' nitoba. 
The President i 1r. Sidney F.. qmith and he isindeed, 
very much interested in undertF.kins' a. nropoýition such VA 
you have set forth. In thn openin7 mpetinr of the 'Tnturr)l 
History Society, 11r. Cartwright brois'ht before th membetrs 
the ratter of prairie chicken research in L'Aitoba ann su;,sted 
that the Society supo-ort a coopnrj)ive project with the 
University,with the i1arierstrons to anpointed io carry out the 
work. The Society wes keen on the iden Pnd,r'r I understand it, 
willintr and able to supwort the nroject. Tbh httoh, of ocurse, 
is that there wn s a stronf objection to brincrn.7 soreone from 
the "States to do the work and the Locietv would owly 
consider suplortinf a local,or at least IanF'-fqdfn n!turali~it. 
In the absence of avnone here eqirnted to c     out the workh, 
I believe the matter h-a been d1roo)rd for the )rePFent. 
 
       From whpt I cin -Rther about Y!r. Pnith, I nm sure 
your letter rill be nell recoived P-d will at lenst wet the 
bell rolling to,'ards makine an openinc, here. Fo7evP.r, I do 
think that it iould be better if the Puý7(stion could come 
from a third party. You ve recall that Ur. Lii is 
particularly iJTtpreted in the Eprmerstrons and in -,tini 
them in Cnnada. It might, be well to write to hNi firbt to rpet 
any suggestions he rpy have on the ainropch. 1c hn onened 
a good many pvrse strinc-s in the IT.,;. rind rmiht be able to 
do so here. 
 
       You ray recall that it in the hope of the fellor in 
Winnipeg - Pitblrdo, art-rizht eot.- to Vpt a set-us at 
the University similar to the q unit system. Thprn hbs VMnm 
even been correspondence, I understand, with the institute 
for help in getting this started. Thould it not b brpt, then, 
to discuss endinvestifite with Yr. Smith the ropblers of 
establishinw wildlife research as a part of th, ,!nlv~tt~s 
function,of nring your exoprience rmid and aid, srpentin7 
the prairie chicken as the loR-ical problem nd the  amerstroms 
as the msnpower.   Thy not su -talso, thn-t the Delts 
Station might be used as a field headouaftern and laboratory 
for pralr~e chicken tudles end other wildlife problems which 
may be undertt)ken by the Univer .ity. 
        I must be' in '7innine7 next week and I Ph'll try to 
 uncove'r Pnytbinj more that has be,.n done yrand spid about this. 
 
  

					
				
				
 
 
 
 
       I gaive you the cost of hatobery operntions as Pbout 
$1500.oo the other dcy. Now that the lodgre i- closed we 
have gone over the records carefully and find that the actual 
cost in 1978 for hatchinv and rearing F% birds and carrying 
135 through the winter was ý,14'1.00 This included I-r. '7irds 
salary for 4 monthp nt 'tl'-..5.00 (included on bhtchery costs because 
he had to hire outside help to care for his lodze and pxoperty 
duties durin r this period) and an nssistint for 6 months at 
175.00. The cost of feed coal,rasoline ,hay etc. , included 
in the above figure ,wasN541.80. 
 
       It would serim to me that ,'e Phould keep our opernting 
costs es close to this as possible. It seems only fair to 
pay the superintendent the same at the sunier assistsnts and, as 
you have suu-ýested a twelve-month appointr'ent, this would 
bring the cost to around 175O.O0  . An Ps~iptant 7ill bh necessary 
during "ay and June as the hatchery job is 24 hr- a dny during 
this period. At 4'75.00 a month this would bring the bill to 
$19o0.00. 
       It should be explained that the the detailpd hatchery 
operations involve only the period bntvfen Mrvy I and ffoventberl. 
For the winter months thrre is no necessity for a full-time 
operator. I would sugest that the superindendent be Ronointed 
only for the Six-MTonth period, reducinrr th- oper-ating costs to 
$1oooo. This will lJeave the responslbility for the hatchery 
durinp- the wrinter to Ward and me. Trd is wi~llng to do this 
as he has before during my period in the ftntes. 
 
       In regards to your second question 1ýr. Wlsd snys th 
Mr. Bell would like to transfer the Uptchery !-gFinninr in 1940. 
 
       The only criticism of the draft is &n the statetent 
repgrd-in Mr. Bell's contributions. '.rd suirywsets that t 
"buildings" should not bc included Pnd the sentence should road;

"Yr. Bell will furnish the ust- of his landduck bntchery and 
equipm:ent on the Delta !,arsh ---"

Dear Professor Aeopold: 
 
 
       Enclosed is a copy of a letter to Arthur describing 
some characters in the cloaca in waterfowl that appear to 
be an excellent index of age. We have checked this in a 
large number of birds and I feel confident that it is a 
reliable character. 
 
       You will remember that our idea for sexing ducks 
 in this way was suggested by the poultry industry. If it 
 is a good age character for waterfowl, why wouldnt it hold 
 for gallinaceous birds? During the last week I have had a 
 chance to examine a few sharptailspinnates and ruffed grouse 
 and find that the structures and differences in the cloaca 
 are essentially the same - that adults can be distuinguished 
 from juveniles and males from females. I say this with some 
 hesitation for I have been able to opeb but a few birds and 
 I have no check for age. I think that a cariftl examination 
 of pheasants where one might work with birds of known age and 
 sex might be worthwhile. 
 
        The enclosed sketches are of mallards but the parts 
 are quite similar in the grousethough the male parts are 
 not as easily found as in the ducks. I am passing on my notes 
 on the ducks to the Hamerstroms in the hopes that they may 
 have a chance to work something out during the open season. 
 
        The lodge has been full sinee the season opened and 
 we have looked over more than 1000 birds since the season 
 started. Mr. Bell is still here and will remain until the 
 end of this week. 
 
        I have held the first news letter up until it could 
 include something on the bag tally. It will be along in a 
 few days. 
 
        Sorry thateyeu are unable to make your hunting trip 
 to Clandeboye this year, for the geese are hanging out there 
 now. 
                          Sincerely yours,

                                          I have your letter of October 4th.

 
                                          I feel exactly as you do about
this 
                          and don't know what there is to be done unless

                          Senator Walcott calls a meeting of the Executive

                          Committee. 
 
                                          I am writing Mr. Bell per the attached

                          and hope that this will hold things for the moment.

                          In the meantime I think it might be well for you
to 
                          draw up a simple cooperative agreement as of last

                          March covering the entire proposition. We must
have 
                          our Executive Committee approve the three-year
part 
                          of it but I don't think we'll have any difficulty

                          doing this if the Senator will just call the meeting.

 
                                          I can appreciate your feelings
in this 
                          matter and also Mr. Bell's and I can only sympathize

                          with them one hundred percent because they are

         Dear y. 4oii1 
 
                       I saw Snator Walett the oer 4q 
         ftr a brief period in this office. 
 
                        I discussed with him ttatively 
         your proposition onorning the work at Delta sd 
         taking over the adinistation of the hatchery. 
         Ea favrs this as heartily as do I but it will be 
         necessary for us to st the approval     ou 
         Exeoutive Cemittee to undertke this proposition 
         on a three-year basis# 
 
                       The enator has agreed to call a

          Dear Albert I 
 
                    I think you have uncovered something in the differential

          sex ratio* In different kinds of shooting. I would strongly encoursae

          you to develop this further. 
 
                   Tour directions on Clazdeboye are very explidit and very

          tespting, but I am afraid I have been out on W 8.C.8. trip so long

          that there is no chae this year. Let's call it a date for next
year. 
 
                   On thinking further on the matter of inalmlsnt, I an inelined

          to ngre that it would be better for you to mroll the seceond sester.

          X think it woul be Important that both yvur thesis and yor examination

          take place at a time whea yo are restered. 
 
                   While I was in the Navajo country I had a chance to pick
up a 
         rug for you and Joan. I did not ship it to Delta beeuse I was afrai

         of mi-ups on duty. ind besides I knew you would hwe more need for
It 
         here than at Delta. Accordingly we are holding it at the house.
I 
         thought I would mention this beoase you are probably worrying ibout

         house furnishings for the winter. 
 
                   Tis is Just a preliminary note. I will have lots nore
to 
         write to you about later. 
 
 
Yawrs as ever.

uvar Professor Leopold: 
 
 
       The season opened bioiiaay wiT.±, Li.  aoLJ. a8. a party 
of four at the loaw.e. Shooting has been excellent and 
we have had a chance to look over a large early bag. 
Mr. nell expects to be here for a month which should give 
us a chance to handle more birds than last year. 
 
       You mignt be interested in the mallard bag. Birds 
shot over decoys or on the lakeshore are mostly old males 
or juvenal males and females. Jump shooting bags are 
composed almost entirely of adult females with soft 
primaries. We are classifying ll the baws this year 
according to the type of shooting and t think there will 
be some interesting notes. 
 
       I have not had a chance to explore the roadr 
to the east beach at Clandeboye but Mr. Ward says that 
it popsible to get there by car. He suggests, however, 
that it would be better to come in from the ielta road 
end hunt and camp on the west beach. yr. Bell does not 
use this land nor is it hunted by anyone else. The nhicken 
season is October 4-- 14. If you find it possible to plan 
a trip, I shall make arrpngements for a plece on either side of 
the bay, as you wish. 
 
       In regards to enrollent in the TTnilvrsity, Vivian 
informs me thpt I still must enroll as a non-resident. This 
I can do now , of coirse, But if it would be possible to 
enroll in 'ebruary and take my degree before I left in the 
spring I would rather do it that wny, for I can hardly hope 
to get all this summer's material together by the end of mm 
enuary. 
 
       Your short visit was a disappointment for we had 
hoped for a longer visit. I hoipe that next year you 
may be able to be h,re lona enough for F re1 stry. 
 
                         Yours sincerely, 
 
  

					
				
				
 
 
 
  THE SPORTSMAN'S CREED 
 
 
  Dedicated to all those who believe in the 
Maintenance of our Wild Life, and who are 
ready to be good Manitobans and Good Sports. 
 
             MY BELIEF 
I believe that- 
  1. The Wild Life of Manitoba is ours to 
maintain rather than to destroy. We hold it 
in trust; the rising generation, as well as this 
one, is entitled to benefit from it. I am one of 
the trustees. 
  2. If the father today exceeds the bag 
limit, his sons tomorrow will be deprived of 
the most enjoyable and most healthful of all 
outdoor sports. 
  3. The conservation of our game supply lies 
very much more in the hands of the sports- 
man than in the hands of the Game Guardians. 
  4. Manitoba's game birds, more than any- 
thing else, have been victims of that paltry 
quibble-"lf we don't get them, the people 
'across the Line' will get them." 
  5. I should remember that though the 
ducks go south, yet they are Manitoba birds. 
With ducks, as with humans, where the house 
is built and the family raised, there is home. 
  6. Manitoba has the greatest duck-breed- 
ing area in North America. Recognized 
authorities, after an exhaustive survey, state 
that this is true of the marshes north of Lake 
Winnipegosis. 
 
           MY RESOLVE 
Therefore- 
  1. I will not abuse opportunity. I will not 
be a "game hog" simply because I expect to 
escape detection. 
  2. When I take up my gun I will not lay 
down my claim to being a loyal, law-respect- 
ing citizen. 
  3. I will help preserve to the rising genera- 
tion its rights in our Wild Life.

              Dear Aldo: 
 
 
                                     Re - Bird BandinL 
 
 
                                Thank you very much for your letter of 
              September 9, 1939, and it is interesting to know that you are

              about to summarize the returns for waterfowl banded at Delta,

              Manitoba. 
 
                                It happens that the 21 duck "returns"
you 
              mention were from the oldest lot of reports this office had
on 
              hand. The system in use between this office and the United

              States Bureau of Biological Survey is for that Bureau to send

              the original letters reporting returns which concern Canada

              to this office for our use, after which the letters are returned

              to the Survey.   Further, it is believed that before original

              letters are sent to this office by the United States each "return"

              is copied on a Return Card (Form Bi - 137) in that Bureau.
These 
              cards may be sorted into various combinations of data by means

              of electrically operated sorting machines. Any information
on 
              these cards could be obtained from that Bureau. 
 
                                At the moment we have several thousand letters

              involving returns for hundreds of banding stations dating from

              1936 to date, which have not yet been dealt with. This office

              is dealing with this material as quickly as possible, the main

              difficulty being shortage of clerical assistance. 
 
                                It is my understanding that the Survey usually

           I advises all banders by means of card notices concerning all
re- 
              turns received before sending the original letters here for

              action. 
 
                                This being the case, the Delta station should

              now have Biological Survey card advices for returns in the
letters 
              we have on hand; we do not know for certain, however. 
 
                                Since, apparently, both the United States

              Bureau and this office are advising the Delta station concerning

              returns, it would be advisable to watch for duplicates. 
 
 
 
                                            Yours faithfully,

           Dear Royes I 
 
                    During    receant visit to the Delta duck station, 
           I noticed tht banding returns for some 21 ducks had reeenUt 
           been received from your office for dcks killed in 1935. 
 
                     I realiso, of oourse, the difficulty of findi 
           safficient clerioal help to kee retuas ip to date. On the 
           other han, we are about to mumariso all Delta banding returns

           to eM iwlduAing 1939 aMd would like to know before working on

           this manuscript whether there Is likelihood of other delyedy.

           rqworts which might subequently change the data. Osan you give

           me a general appraisal of whether more deferred reports are 
           still in the offingl 
 
                    With best re   _a,

Dear 1*r, Palmrs 
 
     LI letter (attached) tells of the recent Delta 
trip, but in it I could not very well include a new 
slant on the entire usefulnesz of the Delta project 
the outcoe of y visit to the Lover Souris and Des 
Laos refuges earlier in AUgust, C. J. henry, the Lower 
Souris maaer, took me really around and through his 
refuge, and it is a wonder for its chances to study 
photographandand and teach of waterfowl and upland 
same. Lots of sharpta.is, hunkiLes, and pheasants, - 
and 13 breeding duck speciesl And only 240 _-les from 
Deltal 
 
     I don't ýnow the extent of your dealings with the 
.      . ut (a pipe drea  of mine,  erhaps) could we 
team up with them, both to help our studies at Delta and to 
help coach their men with perhaps a s=;nr course at the 
Souris refuge (?) then we really would be :etting soqmewhere 
fast*  Also, we might arran-e to sa e for specimens ,A-y 
of the ducks Which die at some of the botulism areas. In 
tine the Delta duck oollction could be one of the most 
used as well as the largst collection of ducks in sur1mTjr 
plua'ges and of known aes.  xxx And this all ties to the 
"Delta Project's usefulness and objectives". Even though 
we may not find nwE     proper time to offer help to 
Salyer's or Bell's divisions, I feel I should "spill" 1 
ideas to you* 
 
     I reached home SeptemKer 2, but almost at once came 
on into Northern ,lichin for a short vacation and trip to 
visit a couple more refuges, as usual, tryin for more 
bird pictures and collecting pondwetd seedst (Just like 
the posta&n on his vacation,) Nence the explanation for 
nw delay in reporting the Delta conference, 
 
     Tr, Bell aeem ready to help on a 3-5 year proeram,

for good aeure he took us to the Des Laos and Upper 
Souris also. 
 
      I am "wild" about the qflrty am! lsi     of  h  Souris 
 developmentS. It is vst wonderfully adapted for a wide 
 assort;ent of waterfol, shore birds, and upland -.

      I have no adverse oo  nt5. Oly, of course, I 
 am very Raxious that Penry and the rest have better

 our "'elta Projeot" -y ;et studý aterilas and helps 
 in shape for the   h needed idertifloation m uals, etc.) 
 But I an  mazed at the rese(rches already underway while 
 yet so many construction Jobs an otr deeop      t ites are

An annual report for the Delta marsh would have great education as well as

 
scientifoi value. It should be published yearly in advanae of the shooting

 
season. It mW not be possible to get into press in advance of the season

 
this year.

      The Delta work has now matured to a poit where we can appraise Its

 
 value Ad its possible future. It is olear thatj

           It. A personnel has been developed. 
 
      From now on it seem advisabl, to adopt a definite oraaisation (including

 
 a none), to delete fouller responaibility to the local force, to unify the

 
 hatehery and reesrsh operations, and to start to baild up, by publication
and 
 
 otherwise, the identity of the station. 
 
      It seems not impossible that t1he station could expand its future operations

 
without additional eost, for there are certain expansions which can be self-

 
supporting. That is to say, the station can operate as a consulting laborato.y,

 
which undertakes jobs which soimebo  is willing to pr for. A list of outh

 
jobs appears later. 
 
     All that is needed to 3eunch this new plan is: 
 
          (a) Definite underwriting of the present ekeleton budget for 3
years. 
 
          (b) A small publication fund by winter of 1940. 
 
          (o) Assent of the Institute and Mr. Sell. 
 
     The opeortion of the property and improveesmts should eontime under
Mr. 
 
N Ward, as heretofore. The station would operate the hatchery, but wholly
for 
 
research purposes. fte Board of Advisrs should include one Canadian, possibly

     the skeleton budet woul  be the present budget of $2.,00 plus safficient

funds to oprate the hatchery. Sise we do not know what it takes to earry
the 
hatchery, we are sot able to add that item at this tise. te hatehery tad

should include a sumer hatchery assietant who wu      also make skins, as
at 
present. It is difficult to eperte both field operations sad ateohry with

only one assistant for both. The exact allocation of dutiee between the two

 at the hatchery an, tbat Mr. 3e11 approves. 
 
     Tbe two assistant positions, in addition to getting work done at Delta,

 
would of course be a valuable way to train selected students for viterfowl
work.

Dear Aldo: 
 
                 I have your letter of the llth and 
I am glad you approve the Cadham approach. I 
sincerely hope that we can get him to back this 
project. His reaction seemed quite friendly 
and his willingness to stop off at Delta to see 
it is rather encouraging. I know Al will do his 
job there. 
 
                 With respect to the additional funds 
for Peter Tvard--I have simply revised the original 
budget to include this amount. I can appreciate 
that the need of proper skins is essential to this 
study and they would occupy a great deal of 
Hochbaum's time which he probably should be spend- 
ing in the field. 
 
                 With best regards, I am 
 
                                 Sincerely yours,

Dear Professor Leopold: 
 
       Thank you for your considerstion o? the trip. The plas 
now are to leave ugust 14. Thank you ,too, for maktnq the 
arrangements for Peter. I am sure it will work in all right 
on the expense account and it makes it a lot easier here. 
 
       With nesting over and the youny ducks in the pens nearly 
grown we are concontrstir on trapning to mgtch the second 
batch of artificials to be released soon. svre been ke-ping 
close match of the creeks at Robertsons, but there are not 
yet enough young ducks gathered to make a drive worthwhile. 
The mpiority of broods in the marsh appear to be under three 
weeks of age and there will be a great many birds this year 
unable to fly by the beginning of the hunting season. 
                i 
       Confidentally, things are not running too smoothly 
here. Nothin7 about us, but a numbpr of the lascal 
roustabouts who once worked here have been continually 
threatening Ward and I am afraid he has fears for his life. 
He wants to get away and may ask that the hatchery operations 
be turned over to us if things do not clear up soon. I'LL know 
more about it when you come up. 
 
       I hope that we can ease Miles' feelings when we 
are all here together. I guess this has been a hard spring 
for him. 
       Plepse feel free to come to Delta any time that is best 
for you. September 1 -10 will be fine.

                    Dear Aldo$ 
 
                                   I am sorry that absence from the office
for 
                    a couple of weeks has held things up but I am attaching
here- 
                    to check in the amount of $320.00 in accordance with
your 
                    letter of July 21st. I am arranging to add to the budget
the 
                    #30.00 for Peter Ward. I am sorry that this has not been

                    going through regularly in the past but please don't
think 
                    I am blaming you. 
 
                                   I have the copies of your correspondence
with 
                    Al Hochbaum and agree with you that he should accept
the 
                    invitation of Mr. Main to aocompany Mr. Cartwright on
the 
                    air survey of Manitoba and Saskatchewan. He can lose
nothing 
                    by such a trip and undoubtedly gain considerable experience.

                    From my brief observation of him I do not think he is
going 
                    to say anything or sign anything not in line with Institute

                    policies. Al has impressed me as being a pretty substantial

                    young chap who weighs his words oarefully. 
 
                                   You may be interested to know that during
June 
                    I wrote Joe Cadham of Canadian Industries Limited telling
him 
                    about the work of the Delta project and suggesting that
they 
                    might like to renew their former contributions to the
American 
                    Wildlife Institute, to be earmarked for the Delta project.

                    Mr. Cadham has just written me in accordance with his
letter, 
                    copy of which is attached. I am sending a copy of this
also 
                    to Hoohbaum so that he will be prepared to greet him

Dear Morta 
 
          Thanks very wn  for the August pyroll. Do I uderstand 
that the additional funds for Peter Ward are actally added to the 
previous dge*t or are we merely eathorised to take them out of the 
sargin for expense that had already been allotted? In either evat, 
I appreciate your approval of his partmwtime employment, but Z would 
like to know whether the total is the s-ze as it was. 
 
          Tour move to Interest Mr. Cadbam sounds to se Ike a veW7 
good one. I remember his pleasantl from ow eploy     t by the 
Auntion Institmte and have written him as per carbea attached. 
Tou m   be assured that Albert will hold up his end at the time at 
his visit.   Maybe Miles and.r will be there also.

Dear Professor Leopold: 
 
       Mr. Main has asked me to accompany Mr. Cartwright on 
the air survey of Manitoba and Saskatchewan next week. I 
feel that I should not accept until you have considered the 
matter.   The trip will take four days and we will cover 
most of the breeding grounds in the two Provinces.   It is not 
a cencus this year but more of a look around. 
 
       Ducks Unlimited is making it their policy to have observems 
from the outside accompany all of their air surveys and George 
baunders of the Biological Survey is going in the other plane 
to the more northern breeding grounds. The question,of course, 
is of time and whether or not the Institute would want one of 
their men to tag along with Ducks Unlimited 
 
 
Sincerely,

Dear Prof. IeorFold: 
 
      This is to ac'21cnled7e receipt o, carbons of 
letters to Albert and to Palner, relative to the 
Delta bud,'et. Before oonmuertin- on its details, let 
r-o eoxress n; sKnrise that rracdiall-y since a y:ear 
aro- m. status seems to have been thiat of "technical 
advisor" rather than "coorerrtoras we started out. 
True, 1 made no srocific bid for Institute help, but 
was wor]kin- under the assumtic-n all alon7 tl at soi"e 
part of the available funds woeld be used to furtler 
ný,r research- the plu~ama'e studies, etc.- as well es 
that most cf it vio'lc bacl the more nearly full-time 
-anrsh ecoloy studies of Albert. 
 
    I have all aloni su ýes-ed and approved payin ,:ete 
ard for inakin,, skins; but I do not see ho- i can assurLe 
the role of "advisor", lay 7T oe!m expenses to Dolta, and 
in turn rake any headwa' with the studies I first asked 
for Institute help with a year a-c last April. Please advise 
i-here and how T have slipped, if I have. Also we should 
have a more defini e un'orsban'in :s to just what if 
azyrt inr of Albert's observaitions and s-ecinmens are 
comnlrl this way in teturn for the initial boost end 
continued helps I have trie to give hin. 
 
    The rush of TPA activities here, plus Sui=rer School 
Teachin- have not helped any as reg-ards ýorrespondence 
with Al eand the hards, or with yourself; but I amr very 
anxious to keep thin-s ironed out as .e -o-- or else 
there can be no "five yrear" cooopration ' na joint 
Delta project. 
 
 
                Sincerely yoirs,

                    Dear Prof. Leopold: 
 
                             Thanks for yo'ir letter of the 24th, 
                     indicating that you believe the amount of " 100

                     wuill be available in travel expenses if I return 
                     to Delta as planned. But does this mean that 
                     you are squeezing yourself out of a like sum? 
                     Your trip is even more important than nine, and 
                     I do not want to be small in this matter, even 
                     should it mean that I have to give up the trip. 
 
                             Sorry you cant take the longer auto trips, 
                    but even I do not like them, and count them work 
                    and loss of time except for the roadside scenery 
                    and chances I may -'et to photograph.-- By the way, 
                    I nor; have a Leitz enlarger for the miniature film,

                    and shall be printing many of the Delta shots not 
                    yet seen in any but negative form. You will receive 
                    these for your files where they will be available 
                    to Albert and yourself for any use. 
 
                             The best time for me to go to Delta is 
                    August 10 to 30, or Sept. 1 at the latest. Surely 
                    must overlap our visits somehow. 
 
                             Very glad Pete is to get cash from the 
                     Institute. His work is good and it will "set"

                     better at Delta, than otherwise. I want you and 
                     Albert to begin dopin!g out disposition of specimens

                     for as yet you recall there has not been any definite

                     decision as to how best to do this so as to make 
                     material available to all of us. Shippinr, birds 
                     back and forth helps complicate this, a bit. 
 
                             Trust you do not take offense or misunderstand

                    my last letter in which you may find me a oarently 
                    "peeved" at not being listed as cooperator
instead of 
                    advisor. It is my belief that I have rot pushed my 
                    plumage studies enough; and also I knoir you are very

                    enthused over the good work Albert i 961i  can do.

                        We had $400 set up for Alberts exenses and $200 
               for ourselves. Through oversight I neleotad to take care of

               Peter Ward and when you called my attention to it I had to

               charge this liability against these Oepnse Allotaets. It 
               will rweuoe them by $240. i see no reason, though, why lam

               shouldI not coQ110t expense5, up to the $100 or~igially con!''

               teoplated. 
 
                        I am obliged to discontinue making long drives a

              hbime rertfully mst turn down your invitation to go up with

 
 
                        My available dates are limited on one and by some

              pheasant e   rments whioh I cant accurately    ate at this

              time but whi   mill probably fall between Augst 15 and

              do some wrk for the Soil Onsuevation Service binnain    about

              Sptember 10. Rogy, then, my trip must fall between 
              August 25 and Setember 10. Even if it should prove ipssible

              for us to be there d~uring extly the same period, it would

              seem that we can probably overlap and. thus excange observations.

and early October.

My dear Aldo, 
   I haive just red. your letter to Dr. Bell dated July 6th 
on the question ofsupervision.   I am delighted thuýt Hicks has 
been visiting the wild life units.   Your letter is very thought 
provoking as most of your correspondence is. 
 
   I am 4ust back from two weeks fisling in Newfoundland and 
am flying tomorrow to Southern California with the President 
of Carnegie Institute to work on some problems connected with 
the 200 in. telescope. Will be back about the middle of 
ktugust prepared to give a great deal more time than I have 
previously been able to to the affairs of the Institute as I 
have declined to accept another four years appointment to the 
Welfare Commissionershio. Will probably be in Washington late 
in August looking into the affairs of the Institute and calling 
a meeting of the Executive Committee and making some definite 
decisions in connection with policy. 
 
   Best regards.

             Dear .lbesrti 
 
                       You are right that $300 for a taxidermist was included

             in the January 9 bud4get but omitted through oversight in my

             June 1 budgot. The monthly rate of $30 which you mention is,

             however, lower and for a longer period than was originally oon-

             templated. Thirty dollars from April to Novmber would be $4RN,

             Since this has sud psychological importance, we had better 
             simply take it out of the funds for your expense and the smal

             fund set up for o~enses bV Pirnie and wself. I will try to 
             get from Mort Palmer on August I enough to ake up the arrears
to 
             date for Peter. 
 
                       Ry file oopy of the June I budget dos not indicate

             that a carbon was sent you. On the ohanc that this was acci-

             dentally omitted, I inolose a copy herewith.

Mr. Aldo reopold 
Professcr f Wildlife anagement 
University of Wisconsin 
Madison, Wisconsin 
 
 
Dear ProfessoT teopold: 
 
 
       We realize the difficulties involved in working out 
the budget problems and hope that you will not feel the need 
to push things on our account. 
 
       In regards to Peter, we discussed a proposed budget 
with Miles in adison"last winter. In considering the 
possibilities of bringing up an assistant this season, we 
felt that it should not be done unless we could allot a 
small part of the budget to cover some of the work that 
eter is doing, for it would be hardly fair to bring someone 
n from the outside to do the same work geter was doing on 
his own. 
 
       A report of the budget was prepared and a copy sent 
to  r. Palmer and to Mr. Bell, I believe.  I did not get a 
copy of this , but as I remember it,the assistant and Peter, 
were to be put on a similar basis for three summer months, e 
Peter to take care of the bulk of the preparation work and 
the assistant to work with the sex ratio and plumage study 
chores in the duck house. Peter is on Mr. bell's payroll 
but it is only for part-time work cleaning tanks, feeding, 
rusning the incubator OW . in the duckhouse. The proposed 
summer pay for him was to cover the rest of his time with 
us from April until November and would amount to about 
$30.00 a month. 
 
       While I am afraid that we would have a hard time to 
match the skinning work Peter is doing, I am sure that he 
would be glad to do it for experience alone, and I am sure 
that Mr. ell would be glad to pay him,aside from his 
contributions to the project,for thip work. However J think 
you will see how important it is to Peter and to Mr. "ard 
to have his work included as part of-the project. I know 
that it means a great deal to Mr. Bell to have him carried 
part-time by us, for he is personally very much interested 
in Peter's abilities. 
 
       I had not brought this up before because I knew that 
there was nothing definite on the budget. But now that Lyle 
is here and knowing of the proposed budget of last winter 
through Mr. Bell, The Wards have been a little hurt that 
there has been no mention of Peter's work 
 
  

					
				
				
 
-2- 
 
 
       August will be fine for your visit to Delta and we 
are gld to know that it will be for more than a week. *ard 
does not think the a shooting season vistt would be out-of- 
plece, and if Miles chooses to come then it will be all 
right. Few deepwater broods are more than a week old now 
and you will probably be here in time for some banding of 
young. 
 
       We have started to release the first pintails and 
mallards this week. I believe that Lyle told you that the 
sex ratios of the casulties ran rather heavily towards males. 
In pintalls the sex ratio of P-l birds we have examined 
so far, including the first releases, was 61 male~to 39 
females.with 128 birds. 
                         Yours sincerely,

                    Dear Aldot 
 
                                     I have held off on the July 1, 1939
check 
                    hoping to have the agreement signed and future payments
made 
                    in accordance with that agreement. However, I have just

                    received a letter from the Senator saying that he will
be 
                    away for the entire summer and that he will not call
a 
                    meeting of the Exeoutive Committee until after the middle
of 
                    September. That means that the signing of the agreement
on 
                    the Delta project will be considerably delayed, to say
the 
                    least. In the meantime, of course, we will continue tD
make 
                    payments as we have in the past unless you have some
other 
                    suggestion. 
 
                                     Senator Walcott has not discussed with

                   Mr. Bell his possible contribution to the work at Delta.

                   As a matter of fact he said in a recent letter he understood

                   Mr. Bell is in Europe. 
 
                                     I am wondering if you would be willing
to 
                    talk to Mr. Bell about this. If you think I should contact

                    him by mail, I will be glad to do so but personally,
I think 
                    it would be much better for you to follow up your original

                    contact. 
 
                                     Please let me know as soon as possible
what 
                   you think about contacting Bell. 
 
                                     If you can also prod Hoohbaum a bit
to get me 
                   the story for Life Magazine it would be appreciated. I
am 
                   going to New York in a week or so and can take it with
me. 
                   We ought to get it into their hands before the duck nesting

                   season is over. 
 
                                     With best regards, I am 
                                                                   Sincerely,

Mr. Aldo Leopold 
424 Univ. Farm Place

Dear Mr. Leopold: 
 
    Some interesting things are beginning to show up in the sex ratio 
 
data from casualties and embryonic deaths which we are able sex. 
 
The ratio is almost 2 to 1 in favor of the males except'bIn the canvas- 
 
bhack where it is almost even. All together we have sexed some over 200 
 
ducklings. At the end of the season the total from all the hatchery 
 
reared birds will total about 800. This reek we are liberating the 
 
first pintails and mallards. 
 
    I have been trying to get enough weights to make a growth uurve 
 
for every species. I was too late for mallards and pintails and red. 
 
heads and canvasbacks are too wild to molest by catching. The gadwall 
 
seems to be about the fasteettgrowing duck on the curve that I have pl 
 
plotted., however, we have only a very small sample and have to kill 
 
those for specimens. 
 
    I started a trapline for small mammals between here and the lodge 
 
for recreation. A lot of interesting data can perhaps be obtained on 
the mammal populations. 
 
    I have been too busy trying to keep up with Al and Pete to do

Dear Morti 
 
          There it really no rush about the execution of the 
final papers. It is all right to wait until the Iheutive 
Committee has met at the end of June. The only thing that 
worried me was whether to 09M Bowls up, and you have asared 
me that I should. 
 
          The temporary chcks may continue to be made out to 
me, but when a formal agrement has been reache. the checks 
should be made to the University of Wisconsin. 
 
 
          I hope the rWeieed 1u4get Sent you the 
may ma~ke it easier to figure things out.

                    Dear Kldo: 
 
                                  The only difficulty about the delay in
signing 
                    the agreement is that Senator Walcott feels it necessary

                    that he have the authority of the Executive Committee
to do 
                    this. The Executive Committee has not met and probably
will 
                    not meet until after the end of June. 
 
                                  I have written Senator Walcott to see if
he would 
                    be willing to sign the agreement anyway. In the meantime
I 
                    shall continue to forward to you the necessary funds
as we 
                    have been doing in the past. 
 
                                 Would you rather that these checks be made
out 
                    to the University or to yourself as we have been doing?

                    Please let me know exactly how you want them made out
and,if 
                    a change is in order, the exact name of the individual.

 
                                  By now you will have received my letter
regarding 
                    the employment of Lyle Bowls. Senator Walcott has instructed

                    me to continue to provide you with the necessary funds
for 
                    this project and I see no objection to sending Bowls
up to 
                    Delta for the summer. 
 
                                  Senator Walcott is very busy trying to
get his 
                    affairs in Conmeatiout straightened out and he just hasn't

                    had much time to give to Institute matters. I hope he
can 
                    take care of matters in the meantime. 
 
                                                         Very sincerely yours,

 Dear Aldoe 
 
             Thank you for your letter of the lt. It came 
 like a breath of cool, fresh air in this over-heated Wash- 
 ington gulley. 
 
             I am delighted to have this definite budget for 
 the Delta project. I have been feeling around in the dark 
 and getting nowhere. Now I can get my feet on solid ground 
 and go some place. 
 
            I've Just received three black and white sketches 
 from Al Hochbaum, which he has sent to us for use in AMERICAN 
 WILMLIFE. I am not going to use them for AMERICAN WILDLIFE, 
 however, until I can submit them to Life Magasine. I have 
 been working up sowe contacts with these folks end have had 
 some correspondence with Al about a proper presentation. 
 When I can get this lined up properly and can make up the 
 proper contact, I am going to turn over the whole works to 
 them in the hope that we might be able to get some good 
 publicity for the Delta projeot therefrom. It won't hurt 
 Al a bLt and neither will it the Institute. 
 
            I have asked Hochbaum to write a very brief state- 
ment of the work of the Delta project as illustrated by the 
pictures and I do believe it can be made attractive enough 
for them to publish. My first letter to Mr. Otis Peabody 
Swift of the Executive Offices of Life Magasin. met with an 
immediate unexpectedly interestw response. Any help you 
can give to this idea will be greatly appreciated. 
 
            I will see that you get the $225 prior to July lst 
for Sowls and Hoohbaum. If you can keep us advised of your 
needs regularly, we will do our best to get them to you regularly. 
 
 
With best regards, I am

     Dear Mortt 
              The Delta budget seems to have gotten itself somewhat tangled,
so 
    I am mkitn  out a new one setting forth my unerstanding of the verbal
agioemot 
    with Mr. Bell, plus the previous action of the Institute trustees.

              In answer to your last inquiry, I will need $225 to meet the
July 1 
    payroll for Sows and Hochbaua. I have so far paid Hohbasu, no expense,
but he 
    is doubtless keeping track of his expense and can submit his expense
account 
    when things got untangled.

Dear Aldot 
 
 
           I have not heard from Senator Walcott regarding 
azr conversations with Mr. Bell but I am writing him again 
to see if these conversations have taken place. As soon 
as I have heard from him I will advise you as to his answer 
and also about the student assistant. I do not think 
there will be any doubt about putting him on but want to 
find out what has developed. This ought to be early next 
week. 
 
           In the meantime I have located in our files your 
report of January 9th, which supplements your report of 
September lit, and calls for $2,500.00 in a financial 
summary as follows 
 
 
Ed Ward. Hatchery supervision and trapping.   T, 
    W. Bell. 
Touporary Assistants. Egg collecting, gopher woi 
      be paid by Mr, Bell 
Hochbaum, Maroh-November, 8 moe. at $150     $1 
                             expens * 
 
Technical assistant, June-September, 3 
      moes. at $I0 
                             expense (no car) 
 
Taxidermist, 3 mo. at $100 
 
Inspection. Trips by Pirnie and Leopold 
 
Equiament and supplies (an electric refrigerator 
      for specimens is needed. Buying a new ore 
      is too costly. Ask Mr. Bell if a used one 
      could be found). For other supplies - 
 
 
o be paid by

             The September lst budget called for #1,800.00. I 
take it that this $2,500.00 budget does not include Mr. Bell's

proposed contribution of $1,000.00. 
            I think it is much better for us to handle the 
funds through the University of Wisconsin than through 
Michigan State College as last year. 
            I will try to keep you supplied with whatever money 
is necessary to carry on until we have our regular meeting 
and I can discuss the matter with Senator Walcott. In the 
meantime if funds are delayed unduly please do not hesitate to 
write me.

Dear Professor teopold : 
 
 
       Thank you for referring the Saskatchewan query to 
me. I have answered it as best I could and apparently to 
their pleasure and satisfaction. I am glad to have this cont- 
act and to have been able to answer questions from here, for 
they seemed pleased that someone in Uanada could help them. 
 
       I am sorry that my pictures had left Milwaukee before 
you wrote and are scattered too far to get together again 
in a hurry. I would send Mrs. Swigart a note to save you the 
trouble but have only her husbands address. Hope the cranes 
reached you safely. 
 
       Mallards and pintails are hatching and some of them 
are already in the pens. Some of the wild nests are hatching 
too and we will be looking for young ducks in the marsh. Have 
about fifty nests going and hope to get many more in the next 
two weeks. This week we are concentrating on redheads and 
canvasbacks. The canvasbacks start nesting a week or so 
before the redheads and the redheads drop eggs in the can 
nests before they start to make their own. 
 
       Drake mallards and pintails are starting to gather 
and many of them are losing their spring plumage already. 
You will be interested to know that everyone here feels 
certain that canvasbacks and redheads are much more abundant 
this year thatVthey have been for the last four or five 
years. Certainly there are many more of them than there 
were mid-June last year. 
       We have a scheme for catching females on the nest, 
marking them and robbing the nest to find out something 
about renesting. We know of several females which can be 
approached rather closely and hope to make a try at it 
at least. 
 
                   tours sincerely

          I've been thining about the delay in the Delta set-up. 
If the agreement" is a mentl har.le, I'd be agreeable to your 
disburesng the funds yourself. The only disadvantage of so doing 
is that it would deprive Roohbman of the "resldeont rate for tuition

tees--& saying of about $200 per yw. (The university "tends 
resident rates to all students supported by outside grants disbursed 
throuh the university.) 
          Within two weeks It will be time for iobbauuts assistant 
(Lyle Sols) to leave for Delta. Re has been turning down other 
offers of employeut on the strongth of the verbal asurane that 
the budget at Delta would provide for him for the suw. 
 
          Where in the diffioulty? Is It in the a   nComet with 
Mr. Bell? If you caould give ae some Idea of where the trouble It, 
I might be able, to help.

Dear Professor Leopold: 
 
       Thank you for your letter of May 3 and the check. I am 
quite secure now and, as far as I am concerned, there is no n~ed 
for haste in getting the budget through. 
 
       I am writing to Dr. 2lton and have asked Mr. Pitblado, 
who is getting the prairie chicken work started, to get in 
touch with the Hamerstroms.. There were three pinnate booming 
grounds within hearing distance of the duck house this spring, 
one of them on a plowed field near where we watched the 
stubble mallards last summer. 
 
       Thank you for the sug'estion on the scat analyses. We 
will get busy on an outling and will have much more material to 
work with this year. Yesterday we found a horned owls nest am 
with two young at the edge of one of the study areas. They 
have been after the coots already. 
 
       Dry conditions extend throughout the Prairie region of 
Manitoba this year. There was almost no runoff from the snow 
and the dust was blowing on the wheat fields a few days after 
the snow was gone. We had one rain late in April which helped 
some but many of the sloughs are bone dry. 
 
       We are getting a fairly good picture of the early nesting 
season, though it had been only a few days since we have been 
able to get far enough east to watch the canvasback. The guides 
have been hunting for a week and, following the schedule 
prepared last summer, we have about 300 eggs, mallard and 
pintail, in the incubatoe. 
 
       Crows and ground squirrels are being controlled in the 
region of the lodge and an area of similagnature is 
being left untouched in the region of theT°lodge. toot-one nest 
bntthe4'chtrolled area to crows this week. 
 
       Mr. Main, of Ducks Unlimited, is buying your Game, 
Management for his Canadian offices and field staff, He asked, 
me yesterday if it would be possible to obtain these, twelve or 
fifteen copies, at a reduced price. 
                         Yours sincerely,

                       Dear Mr. Hoohbaumg 
 
                                        Did you see the last issue of "Life"

                       magazine, in which was included a story of the Robin

                       in color by Roger Peterson? 
 
                                        The thought occurred to me that we

                       could get some excellent publicity for the Delta 
                       project if we could induce "Life" magazine
to publish 
                       some of your paintings of young ducks. 
 
                                        Before approaching them I would like
to 
                       get your reaction to the idea. I understand from 
                       Leopold, however, that you have only three such 
                       paintings ready at the present tine. What is your

                       reaction to this idea? 
 
                                        I would also like to reproduce your

                       paintings in black and white in AMERICAN WILDLIFE
and 
                       in connection with a news story in our regular monthly

                       clipsheet which goes to newspapers all over the entire

                       country. If you could have photographs of those made

                       for us at our expense it would be greatly appreciated.

amount 
                        of $200.00 made out to your order for the Delta Water-

                                       I discussed with Senator Walcott very

                        briefly the proposed agreement when he was in town

                        recently but he did not sign it at the time nor have
I 
                        heard from him since. I will try to get this matter

                        straightened out as soon as possible. In the meantinm

                        I hope this check will help carry things along.

   Mr. H. Albert Hoahbaum 
   Delta, Manitoba 
   Canada 
 
   Dear Albert: 
 
             I am surprised and disappointed to learn about the low water
levels. 
   Do you know whether this is representaýtive of ay considerable
area? 
 
             Your observations on the fact that the people in the Carberry
hills 
   do not know Seton is, I think, one of the most illuminating details that
has 
   come uv way for -some time. 
 
             I would be delighted to have you offer to play ball with Ktones

   snowshoe inquiry. I suggest you write him direct, bmt I will be glad to
do so 
   should you prefer it. Lyle might be of help in this connection. 
 
             this morning I went over Lyle's scat and stomach analyses. He
is 
   sending you a copy. It strikes me that you have here not merely a valuable

   report on food habits, but an equally valuable contribution to food habits
tech- 
   nique. 
 
             In order to socurately locate the gaps I would suggest that
you and 
   I~rlo make a rough draft of a paper. This would disclose the gaps and
his work 
   could theo be directod toward filling them. If it is to be a techniques
paper, 
   it might also be well to Include a number of little line cuts to Illustrate
the 
   differences between downs, feathers, etc. You might be playing with these
during 
   the smmer, 
 
             I ai pleased that Ed Ward has been recognised by the Game and
Fish 
   Association. If there is to be a prairie hicken study, might it be possible
to 
   work the Hamerstroms in on it in some capacity? Now that Delta is apparently
set 
   up on a salary basis for a number of years, m ambition is next to set
up the 
   prairie chickon study on some comparable basis and to extend it beyond
Wisconsin. 
   My idea is a *Prairie Chicken Institute which would consist of a liaison
officer 
   plus a small fund to chink up Cracks, but the bulk of the "Institute"
would con- 
   sist of the contributed services of persons working on cickens, including
Hawkins, 
   Teatter, Bartlett, Gus Swanson's crowd, and the Texas crowd. If a Manitoba
study 
   were set up with a man in charge of it, he might be one more of the component

   parts of the institute. Let's talk over more detail when I come up. 
 
             I have not heard further from Mort Palmer, but I have every
reason to 
   believe the Delta set-up will be all ironed out before long. 
 
             I enclose a check for $125, which is the residue in the temporary

   deposit made by Mort and which will cover 5/6 of the payment due you for
April.

Dear Professor Leopold: 
 
       The ice is nearly gone from the marsh and the ducks 
are here in large numbers, particularly mallards, pintails 
and lesser scaup. Mallards and pintails have started to 
nest and we are beginning our nesting study observations. 
 
       Marsh fires have been raging for the past week and 
most of the Phragmites in the region of Delta has been burned 
over. The east marsh has not been touched, however. The lake 
is 18 " below the level of last surmmer,many of the sloughs that 
had twoofeet of water last summer are empty and everything 
is very dry. I am assembling all my notes of the oatt month 
and will send a full account of events. 
 
       Sunday afternoon we took a trip over to the sandhill 
region at Carberry. It is still very wild end beautiful 
and I hope you may have a chance to visit it this summer. 
Nobody there had ever heard of Seton or Thompson except one 
old fellow who remembered him as a " crazy young fool" who 
spent all his time wandering about in the hills. 
 
       I have just finished reading Dr. Elton's Annual Report 
of the Bureau of Animal Population . It occurred to me that 
we might odfer to cooperate with him on the snowshoe rabbit 
enquir$,particlarly the reproduction enquiry mentioned on 
page 26. I realize the necessity of not piling up too many 
thingsbut we are in such constant touch with the rabbits 
that we might easily accumulate some valuable material 
for him if he provided an outline of the information he 
desires. The fact that this is more or less an isolated 
range where the rabbits are never shot might interest Dr. 
Elton. 
 
       Ed Ward has just been appointdd a Director of The 
Man. Fish and Game Assoc. The Association is setting up 
a fund to support a study of prairie chicken in Manitoba 
and as soon as can learn more of the details concerning 
the proposed study I shall pass them on. 
 
       Mr. Cunningham has a sharp eye. Thank you for making 
the change. 
 
 
                         Yours sincerely,

Dear Albert: 
 
 
     It has been winter here again also, and 
that the same weather has hit you. 
 
 
I am not surprised 
 
 
     Keep the orane picture as long a you have an opportunity 
to show it. 
 
     Thanks for the crow map from Kalmbach. I will see that it 
is not published. I have excellent use for it, since six members 
of our 115 class are banding crows for Lincoln this spring. I 
will show it to them. The Kalmbach corresponden"e Is returned. 
 
     Dr. Obner of the University of Munich has been here and 
we were up at Plainfield with the Hamerstroms and Art Hawkins. 
We had some excellent discussions and all of us were sorry you 
could not be there. 
 
     With best reards, 
 
 
   Sincerely yours,

 Dear Professor Leopold, 
 
 
        Thank you for your letter of April 5 and the 
check. I am glad that things are going through so nicely 
and thank you for all the trouble and work you have gone 
through to get this accomplished. 
 
       We are having a sJ~ell of winter again with near zero 
weather and are still spending most of our time scraping 
fat. Nevertheless spring is here and Saturday the snow 
geese passed over flock after flock for almost an hour. No 
more ducks , however. 
       IMay I borrow your picture for another month? The 
Milwaukee - Downer College wishes to have the pictures 
for exhibit and I have asked Meuers to ship them over. I 
certainly appreciate the start you and Mrs. Leopold haven 
given me in getting some pictures out in the'air. 
 
       You will be interested in the enclosed note from Mr. 
Kalmbach. He seems very much interested in the project 
end I hope he will be able to visit us this year. 
 
       This is a bit of a lull before the storm of the 
nesting season and we probably will be workinq on nests in 
another two weeks. I hope to make the most intensive study 
between the bays and lake in the region of the lodge and 
7e are mapping that while the sloughsare still frozen. 
 
 
Yours sincerely,

Dear Aldo: 
 
                I have your letter of the 30th relative 
to the Delta project and I am delighted that Mr. Bell 
has such a friendly attitude and is willing to 
actually spend some money on it. I hope he and 
Senator Walcott can get together on a really progres- 
sive basis. 
 
                You can bet your boots I won't forget 
that trip this summer because I plan on getting 
around and seeing what is going on. Incidentally, 
what are the possibilities of getting some photographs 
of a few of Hochbaum's selected paintings of young ducks 
for use in AMERICAN WILDLIFE? These will, of course, 
have to be Aone in black and white as we do not have 
e means nor the funds for color reproductions in 
AMERICAN WILDLIFE at the present. It won't do Hochbaum 
nor the Delta project a bit of harm to give this a 
little publicity. 
 
                With best regards, I am 
 
                                     Sincerely,

Dear Professor Leopold: 
 
       We were glad to hear of your meetings with Mr. Palmer 
and Mr. Bell. Now that I am here I am in no immediate need 
for funds but certainly am pleased to know that things are 
going along as they are. 
 
       I am glad that I was able to get up here when I did 
for things will be moving rather rapidly before long. We have 
had time to make a fine office and laboratory and it makes it 
a greatd deal easier to have everything in order.and under one 
roof. I am getting all records ,papers etc. filed and in 
place and hope that this will help'to keep things going in 
a businesslike manner. We are also taking this time to preserve 
the needed specimens of adults of known age and the 1939 
collection is already of-good size. The skins are getting 
better all the time too and a fat duck is no longer the 
chore it used to be. 
 
       Saw the first ducks March 29, tallards. Canada geese 
have been going over every day since then. The marsh is still 
frozen but there is much surface water on the ice. The rat 
season is on now and the marsh is alive with half-breeds and 
indians, at least two for every house. 
 
       Crows are abundant. As soon as they got here they had 
a large roost west of melta and there is quite a flight along 
the ridge in the evenings. Shooting is good and the boys are 
bringing in quite a few birds for stomachs and sex ratio, Looks 
as though the early birds are mostly females. 
 
        I'm glad you revised the footnote for the report. Thenk 
you. Fred insists that "Retrice" should be rectrix on page 
three. I hape there will be a chance to check that before 
the paper is printed. 
 
        Thanks for the good word on the pictures. The Milwaukee- 
 Downer College asked for them on your recominendation and I 
 am letting them know that they may use them. 
 
                             Yours sincerely, 
 
                                       ac4Z1

Dear Hoyee: 
 
 
          Here is Hochbaum's report on 
It was given at the Detroit Conference 
Transactions. Some additional subject 
report, Hochbaum hopes to place in the 
 
 
the 1938 work at Delta. 
and will come out in the 
matter, reserved for later 
Canadian Yield-NaturaliSt. 
 
 
          Pirnie and I went over the work yesterday with Mr. Bell. 
All three of us are very appreciative of your friendly help, and 
would like to be sure that this proposed report meets with your 
approval. If you have any comment, will you let me know? 
 
          We have recently had two exhibits of Hochbaumsts Delta 
paintings here at Madison. They were well received. The Winnipeg 
naturalists are including them in an exhibit there this spring. 
Should you ever want to include them in any Ottawa exhibit, I'm 
sure Hochbaum would be much pleased. 
 
                               Yours sincerely,

                                           I am attaching hereto a cheek
made 
                          out to your order for $200.00 to cover the immediate

                          needs of the Delta project. As soon as I have an

                          opportunity to get together with Senator Walcott

                          and get things definitely straightened out I will

                          probably be able to send more. This will take care

                          of immediate needs, however, I believe. 
 
                                           I am not sure whether this is
the 
                          proper way to have this check made out but I felt

                          that this would save time. You can endorse it over

                          to the agency and give us further instructions.
The 
                          last checks I think were sent to Pirnie at Michigan

                          State College. How should we handle this in the

                          future.

Dear Professor Leopold: 
 
       We arrived at Delta Monday after an easy trip up with very 
little digging. Had a most pleasant visit with the lamerstroms 
on Thursday and Friday. My what a job they have. I never 
realized what difficulties attended chicken trapping. 
       I was surprised to find that spring was h-re ahead of 
us. The redwings and yellowheads have been here for some time, 
and are picking territories with the tops of the reeds just 
sticking out of the snow. The first crows arrived on the 21st 
and are feeding now on fish out on the lake, lings left by 
the fishermen. 
 
       Ed Ward and I are busy converting one o# the mink houses 
into an office and laboratory. Its going to be a grand place. 
Pete and I have made a good start on the 1939 skin collection -- 
making up birds that died during the winter. I hope that we 
can get a good collection of ducks for tebestudents as well 
as the plumage study colleation. 
 
       Everything is melting rapidly and everyone expects ducks 
any day now. There should be some open water in the marsh 
within a week. 
 
       I want to thank you and Mrs. Leopold for the many nice 
things you did for me this winter. The tea. was grand and I 
appreciated it more thanl can say. Thanks, too, for the help 
on the paper . I got a great deal out of going over it with 
you. 
 
       Sorry I couldn't let you know of our arrival before this. 
This is the first mail out since we came. 
 
 
Yours Sincerely,

                   I saw kort Palmer at the Itmak Walton League meeting in

          ChQ s  Friwda and he eantirely approv of your d"rbare for
Delta 
          on schedule. 1f feels rertain that the Institute not only inteas

          to oontinue its support bat that the assistant for this year will

          be provided for. He has not yet beta able to stratgtea ot the o&-

          fuston as to the trustes' action but will do s before long. 
                   Miles and I are meeting Mr. Sell in Mit*.o, Koafty, March
27, 
          at which time I hope to get some more 4efinite information about
cn- 
          tiaity and about future plans. Mort is stro>1y in favor of setting

          up & five-year pr=. Of ourxse his attitude 4do    not comit
the 
          Institute, bat I ws pleased to know of his attitde. I asked him
to 
          visit Delta this suinw in order that some meber of the Institute

          might have first-had knowled4e of the wor there. 
 
                   Mort tells me that wr report is horter them man  of the

       Dear Morta 
 
                 It is hard for me to  nerstand how the trustees should got
on- 
       fused between supervision for the Ton Units and operating funds for
the 
       Delta project. Certainly we do not need an additional supervision
for 
       Dqlta. If, however, fiscally speak4in, $3,000 is avallable for both,
the 
       I see no choice but to segregate $2,50 of it for Delta in accordance
with 
       m report of January 9, and use the balance for giving the scientific
super- 
       vision idea a brief trial in one or two local spots. I am not sure,
of eourse, 
       that we could get aybody. 
 
                 This new twist is a little embarrassing for me because I
had alread 
       begun to consult with the Bioogical Survey about possible personnel
for the 
       scientific supervision function. 
 
                 If we must consider that project as either out or reduced
to very 
       small proportions, I hope yoa can let me know at an early date so
I can reduce 
       our proposals to fit the reduced funds. 
 
                 I have revised the minutes for pages 3 to 6 of the roug
cop 
       sent me. but I have ,revised them to fit my own recollection of what
happened. 
       If this must be twisted so that the $3,000 covers both Delta and the
supervision 
       project, then further modification in the minutes will be called for.

 
                 I oan appreciate your difficulties and I can see that we
probably 
       must drop or wholly drop the scientific advisory project. 
 
                                          Tours sincerely, 
 
 
 
                                                    do Leopold 
                                           Professor of Wildlife Managewet

 
       P.S. Since writing the above I have received the attched letter from

       habrielson which somewhat ohangethe acceptability to the Biological
Sryrv 
       of advisory help. Gabrielson practically limits aceptability to members
of 
       the Technical Coittoe. Under these circumstances perhaa.ps it is just
as 
       well to have the allotment out down to a very low point, since I am
not at all 
       our* that wV msmbers of the Technteal COmmittos can spare any time
for 
       advisory servooe. iny retam kabriolson's letter.

                     Dear Aldo: 
 
                                     I have deciphered, very unsatisfactorily,

                     the minutes of the meeting of the Trustees meetbV in

                     Detroit. You may remember that that meeting was rather

                     hectic insofar as the writer was concerned and that
I 
                     was in and out of the room frequently. The minutes 
                     were taken by several different peqple,alternately.

                     Some of the notes are very difficult for me to decipher

                     and I am, therefore, asking you to go over certain parts

                     of this and straighten me out and make a better connection

                     between the various subjects of discussion. I would

                     certainly appreciate your doing this as it would be
a great 
                     help to me in getting this matter straightened out.

 
                                    One thing about which I am especially

                     concerned about--that is, that in talking with Senator

                     Walcott on the phone the other day with respect to the

                     status of the Delta project, he stated that that was
all 
                     taken care of in the $3,000.00 item appropriated for
your 
                     colasultation work at that meeting. This does not at
all 
                     jibe with my recollections nor with the notes of the

                     meeting. I wish you would please check me on this and

                     advise specifically. He says the project has been 
                     officially okayed but I cannot put my finger on the
official 
                     record. 
                                    I will discuss with him shortly your
desire 
                     to get Hochbeum started early at Delta. 
 
                                                      Siner      O

        Dear Mr. Bell: 
 
                  I am sorry not to be able to be in CAiaeo Monday. A 
        bunch of osmittee meettings were called in a4vance of the Detroit

        conferene, which forces me to be in Detroit by Sunday noon. 
 
                  In my wire I su-ested WeAnes4*y evening as an alternativo

        sine* I have to be back here for a olass Thurday mornin. I mow 
        gather from your lettor, howeser, that you will nt be back in hteao

        until the following wek. 
 
                  Since our nsettn- was ort~inaly pro"ected, Pirnoe
imA I have 
        had a      ehanoe to talk thtin-7 over, !und 'he unsettled questions
are now a 
        little bit diffoernt thpn theV were. 
                  We feel the need of a talk with you, but the question to
one 
        of yrr fture preferanoes for the eevelpuent of the projeot rather

        th^n one of detailvl plans for the coming year. This to somethin
 that 
        can be gone over at an time. Let's, therefore, leave it this wy 
        you call vA down to 7hi e at your convenience, preferably within
the 
        next nonth or two. 
 
                 All the above assumes that the Institute can finance the

        latest revision of the 1939 plans which calls for a total of about

        $2,000. 1 have no Idea how the Institute stands on this but will
find 
        out at Detroit net wee. Shoud there be saw uet, I will, of course.,

        let yoa know. The above also assmes that you have no objeetion to
a: 
        of the details of 1939 operations *hieh we he laid out with Mr. TVfr

        and *ih  have been described in the pst erespodene. 
 
                  One thi  I reet Is that you have not yet seen oh 
        Delta paintings. I really believe we have, something there which
MW 
        ultimately equal in valu, the seientifie wor. Kwing your interest

        in that sort of thing, I a anxious to show them to  . Mrs. Leopel4

        ad I are holding an exhibition for  chbb  at our homse sesmte 
        within the next mouth or two. Would there be an  a  e of yer steppine

        off at Madison sometime? If not, I shall bring soe of tbw with me
to 
        Chiago because I want you to see thie.

         Dear Dr. Leopold: 
 
 
         I am unduly dilatory in writing you about 
         the possibilities of our getting together 
         with Dr. Pirnie in Chica-o. However, my 
         plans have been so uncertain that I have 
         put off the matter until I could name a 
         definite time. 
 
         I wired you today that I would be in Chicago 
         Monday. I have a meeting in the early part 
         of the morning, but I can be free by 12:15 
         and I thought we might have lunch at the 
         Chicago Club and then I could remain with you 
         until my train goes at 3:15, or I could arrange 
         to take a later train if necessary. 
 
         If this is not convenient, I will be returning 
         through Chicago either on the 20th or 21st, 
         but cannot let you know positively which day 
         until some time later. However, I will be 
         glad to accommodate my plans to you.

       Gentlemaen 
 
                 Dr. Pirate and I had an unforeseen opportunity to talk over
the 
       Delta project on Januar 9. Our conclusions are sumvarised in the attached

       report. This report deals with organization and finance rather than
research 
       projects. The research projects as outlined in the reort of September
1 
       stand as our current recommendations. Our summer's exprienees have
naturally 
       had a chane to be digested during the intervening onthe and I think
this 
       report is s*mewhat wore mature than the previous one. 
 
                 I feel at present that we have need of consultation with
the 
       Institute and with Mr. bell, not so much on either technical or organisation

       details but rather on (1) whether we should aim toward a long or a
short time 
       job, and (2) whether you have any preferences as to the lines along
wbich 
       Delta should develop. 
 
                 Both these questions are too intricate to be detailed in
a letter 
       but they should form the principal subject matter of the peanding
conference 
       with you. 
 
                 The unavoidable delay in holding this conference has forced
us to 
       give Ducke slirited a reply to their "feeler" of financial
cooperation. 
       Hochbaum has written Gartwright in at nice a way as he could that
there are 
       four cooperator. in the project already and that we are afraid it
would become 
       unwieldy If the ineber increased to five. 
 
                 Time is now so short that in order to avoid useless travel
it 
       occurs to me that our conferene might well be held in conjunction
with the 
       Detroit meeting. If Mr. bell is ant attending the Detroit meeting,
could we

     (Jote: This memo is supplementary to our report of September 1. It 
gives the conclusions reached at a meeting of Pibe and Leopold January 9.

We have not yet had a chance to consult Mr. Bell or the Institute as to 
their views and preferences, or as to financial prospects. This memo is 
written "in the dark" as to these points, and subject to amendmont
on those 
points.) 
                                            the 
     te Outlook. The work has now reached/point where there is more to be

 
done than one man can do. This pressure of opportinity will of corse grow

 
greater with time. 
 
     We think that the Institute and Mr. Be.1 should be reminded at this
tim.: 
 
          (1) That an early decisiou should be reache4 as to whether to aim

              toward a hand-to-mouth continuane, or at a 5 or 10 year 
              program. 
 
          (2) If the former, the program should be narrowed and curtailed

              to quick-dividend short-tine ventures. 
 
          (3) If the latter, do we need to let any new parties in for the

              sake of assuring fnds?   (U.$.B.S.,for exaple.). 
 
          (i) If the latter, Hoobbaun at the end of 1939 should be put on

              a salary basis equal to what he would get if he out loose 
              and got a j ob. (He will get his degree after next summer's

              work is reported on.) 
 
          (5) If the latter, what special kind of achievement interests the

              Institute and Mr. Bell most? 
 
                 (a) Development of Delta as a place for training waterfowl

                     experts? 
 
                 (b) Development of Delta for output of scientific an 
                     educational publications on waterfowl? 
 
                 (we can elaborate these alternatives verbally. They are

                 not mutally exclusive, but both can' t receive equal 
                 emphasis.)

     It is very important that we know the 1939 budet by Apri1 1, beauee

 
students mak. their smer plane early and the beot technical assistats are

 
not available at the eleventh hour. Only the bet assistants are worth 
 
having. 
 
     It may not be improper for us to point out at this time that the Delta

 
project Is a very exating one. VTh very weulth of biological" opportunities

 
and the unbonded coop erstiveness of N1. 3.11's local force create a 
 
perpetual temptiton to attempt too much.   tyltigt begins at 3 a.m. and 
 
ends at 10 p.m. Duties are extremely varied and included everything from

 
painting pictures to diging muck. Diplomatie relations mst be maintained

 
with a double set of bureius, conservation organisatione, and setintists.

 
A broak in continuity of personnel would represent a huge lose of aeeumulated

 
inforu.tion. It therefore seems both fair and wise to pay the *arket"

                 Madison, Wisc. 
 
                 Dear Prof. Leopold: 
 
                           I am rather ashamed at the accumulation 
                 of letters and carbon copies from you that have 
                 not been acknowledged. I had, of course, been in 
                 part expecting to meet with you and Mr. Bell, so 
                 let Christmas rush and rabbit hunts intertere. 
 
                           The visit from Al, Hawking, and the three 
                 boys from Lansing for the waterfowl plumage and banding

                 conference was a most enjoyable occasion- to me at 
                 least; and I look forward to more of just that sort 
                 of informal exchange. 
 
                           I hope the Bell-Leopold-Pirnie conference 
                 can be held before the,9onference; and to that part 
                 of the conference as deals with waterfowl problems 
                 and ecology, technique etc. I most certainly would 
                 think it proper for you to include both Al and Art. 
                 Not knowing Bell, however, I am inclined to think 
                 you and I would be enough for the first, general, 
                 get acquainted phase of the meeting. If I were Bell, 
                 I am sure I would be less free with extra, new persons 
                 present in such a preliminary interview. 
 
                           I agree that the reply to DWcks Unlimited 
                 is not easy, and should await decisions from Mr. Bell 
                 as well as the Institute. There are of course, several 
                 projects in the air, first: Alts study at Delta; second,

                 my plumage and other waterfowl work, and of course the 
                 need for additional propagation plants in the States, 
                 to say nothing of such field work as Art is trying to 
                 get fitted for in his job with the Natural History Survey.

                 I hope it may be possible to create support for these 
                 as well as the Delta studies. But very easily, Al and I

                 could very well get ourselves lost at Delta or the 
                 Kellogg Sanctuary; and this we hope to avoid. 
 
                           When is Ala seminar talk? And would you have 
                 time for a visit and conference if I came over for it? 
                 I can bring or send the color slides, if You and Al wish.

                 A relief project to start soon makes soon best for me.

P. S.   Sutton seemed very glad to include Al's three 
duckling paintings in the Wilson Club bird art exhibit 
at Ann  Arbor. Both there and at the A. 0. U. meeting 
in Washington I had chances to tell of the Delta work 
and the part the Institute and your department are 
playing. There was a surprising intere    shown by 
many of the staid A. 0. U.-ers.    MDP

          Mr. Albert Hochbaum 
          Delta Duck Station 
          Delta, Manitoba, Canada 
 
          Dear Albert: 
 
          I am a little bit disturbed about M4r. Bell's letter, copies of

          which I am sending to Pirnie and Rowan. I, for one, am ready 
          to debate this departure with Mr. Bell. If, how:'ever, you are

          thoroughly convinced that you want to make some light experiments,

          I will, of course, go with you. 
 
          It seems to me that there are several good reasons why new ex-

          periments should not be made. The first is that there is; no 
          trained physiologist or endocrinologist on the ground. The second

          is that since Rowan's original work in this field, dozens of workers

          have entered it; the fact that lighting can produce premature re-

          production is well-known and needs no further proof. It is unlikel:-

          that any important new findings will follow except by more detailed

          physiological work than has heretofor been done. 
 
          Thirdly, if there is additional money, we could make better use
of 
          it by pushing ventures alre'-dy undertaken and in providing a more

          ample travel allotment for you. 
 
          Of course, if you are really convinced that lighting experiments

          would be valuable in connection with your stud, of latitude, that

          might be a different story. Please let me have your real attitude,

          and send a copy of it to Rowan and Pirnie, after which I would
like 
          to have their vote as to whether or not the advisory board should

          approve this departure.   I am not sending copies of this letter
to 
          anyone except members of the advisory board and yourself. 
 
          Te dropped the mallard experiment because the program was already

          heavy enough. I doubt if we should load the program further at
this 
          time. 
 
                                       Yours sincerely,

Dear Mr. Bell: 
 
       One of the Ruralite wind plants,! believe, would provide 
the most efficient and satisfactory lighting for the duck house. 
Ed's plant has provided excellent servire for more than two years 
and a similar plant could be ri#Red up to meet the lighting needs 
of the duck house. ]d points out that gas as well as wear and 
tear for the lodge plant would,in the long run, require greeter 
running expense than the wind plant. 
 
       Aside from the importance of followina up your earlier 
experiments with lightingartificisl light in the duck house 
would permit us to study the effects of light on *'he growth of 
young ducks. You will remember our discussion of this with 
Dr. Rowan last summer. There is considerable evidence that birds 
reared in northern latitudes develop more rapidly than those 
reared in iorf, southernly regions. Certainly the young that move 
down from the north in the fell are further advanced than the 
Deltr young of the year. 
       This is ten important ocolopwiol problem and Pomething 
which must be determined if plumage develonment as a ke- to age 
of young birds is to mean anything to field workers. With artificial 
light the naturel periods of summer livhtinw for several letitudes 
could be simulated in t'e duck house. 
       I hfve ron- over your letter with Ed who bolieves the !-ind 
chbrger would be in mtny ways better than briniing up the lodge 
plant for a temporpry period. Aside from this, however,! feel 
in my own mind thattif we are to light the duck house,the wind plant 
woul' be the most satisfastory. 
 
       Rave had a number of eacellent reports on Peter's work 
with the Natural History aurvey. I do hope it will be possible 
for him to go on to new York after he is finished there. 
 
                                Sincerely yours 
 
 
(Albert Pochbbaum)

     If we are to conduct experiments in respect to the 
     effect of increasing and decreasing light on ducks, 
     it will be necessary to have an electric plant. 
 
     There are two ways of accomplishing this: either to 
     put in one of these Ruralite wind plants, or to move 
     up one of the plants from the lower lodge temporarily. 
 
     I think the latter would be the thing to do. How 
     important do you think this is, and how should we 
     move to accomplish it. 
 
 
                           Yours very truly,

Dear Hayest 
 
The executive committee of the American Wildlife Institute has 
requested Dr. William Rw4 University of Alberta, to serve on 
the Board of Advisors of the Delta 1)tok Station, Delta, Manitoba, 
and he has accepted the appointment. The other members are Dr. 
Pirnie of Michigan State College and myself. An announcement 
of his appointment will probably run in an early isse of American 
Wildlife, but I am sending this letter to you thinkdng you might 
want to run a brief announcement in the "Canadian Yield Naturalist.

 
                            Tours sincerely, 
 
 
 
                            Aldo Leopold

Dear Paul: 
 
In regard to your various letters of November 5, first of all lot me 
correct your impression that we are trying to study botulism at Delta. 
Our Delta group includes no pathologist, and we are not competent to 
do any such thing. If you will read my letter of October 22 anxrefully, 
you will see that we are merely trying to determine mhether botulism 
has a differential impact on sex and age. Since most Biological Survey 
men do not know how to age ducks, we had to send Hochtaum out to work 
over the pickled speciments. Hence, our activity is in no way a study of

botulism, but merely a follow-up on our own age s tudy in duck populations.

 
Dr. Bell evidently appreciated this, or else he would not have instructed

his refuge keepers to pickle botulism-killed carcasses. 
 
As to Bulletin No. 1, Hochbaum is focising all his efforts on its completion

this winter, and you can count on me to let you know in advance when it 
will be ready. I suhgest you tell Mr. Carpentr that we have not forgotten

his generous contribution, and that we will call on him for it when we 
have the mRatrial ready. We are admittedly late in getting it ready, bmt

this is not unal in our kind of work. Something new always comes up. 
 
As to Dr. Needham, I will regard him as informally a member of the Technical

Committee, and I will continue to keep Dr. M1lis on the list until you 
Inform me of further changes. The material on the roposeod salmon study 
sent me with your letter of October 9 went out with my circular of October

9 to the committee. 
                                   Yours sincerely, 
 
 
 
                                   Aldo Leopold 
                                   Professor of Wildlife Msmageent 
P.S. I am glad that the Executive Committee has formally ratified the 
Rowmappointment to the Board of Advisors. I suggest that all of us send 
Rowan copies of important letters on Delta. I also sugest that you run a

little news story, perhaps with a picture, in *American Wildlife", announcing

his appointment. I am also asking Hoyes Lloyd to run an announcement in 
the f0anadian Field N~it ralist."

Dear Aldo: 
 
                Reference is made to your letter 
of October 22nd enclosing Hochbaum's report 
on lead shot experiments and your comments 
regarding it. 
 
                Senator Walcott was in the office 
Wednesday and after discussing the broad phases 
of the lead poisoning situation we are more or 
less agreed that, although the work should be 
carried on, it would not serve a very good purpose 
to give it too much publicity at the present time. 
 
                We, therefore, both of us concur 
in your opinion to leave this matter out of 
print until further verification is made. 
 
                              Sincerely yours,

Dear Aldo: 
 
                Reference is made to your letter of 
September 28th regarding Hochbaum's salary. 
 
                I discussed this with the Senator 
on his visit here Wednesday and both of us agreed 
that there should be some adjustment made in this 
matter. We must, however, await the budgetary 
approval and have some idea of our potential income 
for next year before we can commit ourselves on 
this matter.     I will put it on the agenda for the 
next Executive Committee meeting. 
 
                It might be possible, although I 
think it is very unlikely, that the proposed 
increase could be made up from funds now available 
to the Delta project. This remark is made merely 
to indicate that we are in sympathy with your 
suggestion but at the present time are just a little 
uncertain in our minds as to how to accomplish it 
in the immediate futureo We hope it can be adjusted 
by January 1st, howevero 
 
                                   Sincerely yours,

Dear Aldo: 
 
               Thanks ever so much for your letter 
of the 22nd of October and the enclosure from 
Hochbaum. 
 
               As you know, Dr. Shillinger has 
conducted a number of experiments similar to the 
one outlined by Hochbaum in this report. I do not 
believe that the work has been broken down in 
quite the detail that Hochbaum's work program 
indicates. However, I think it is something that 
should be followed up.  I agree with you, however, 
that until more specific information is gathered 
it should not be published. 
 
                                Very sincerely yours, 
 
 
 
 
                                J. Paul Miller,

P. S. I plan to take up the matter of Hochbaum's 
salary this week when Senator Walcott comes to

and approved that Dr. William Rowan be appointed

                              Please accept my thanks for your 
 
           invitation of the)4th inst. to serve in the capacity of co- 
 
           adviser on your Delta Duck Project, a distinction that I greatly

 
           appreciate. I met Dr. Aldo Leopold many years ago and have 
 
           a great respect for his work. It will be a pleasure to be 
 
           associated with him in this manner. 
 
                              I would be much obliged if you could 
 
           send me any printed information of the scope end activities 
 
           of your Wildlife Institute. I am familiar with its activities

 
           in a general way, of course, but feel that a more intimate 
 
           acquaintance with its detailed set-up and aims and objects 
 
           would be of value to me. Anything in this nature that you can

 
           send me will be much appreciated. 
 
                                             Yours sincerely,

                          Dear Aldot 
 
                                         Reference is made to your letter
of 
                          October 22nd relative to the publication of 
                          material from Delta and your inquiry regarding

                          the contribution of $500.00 promised by Mr. Carpenter

                          of Du Pont. It is our understanding that this 
                          amount is not to be collected until the publication

                          is ready for the press. 
 
                                         Although there is no immediate need

                          for the detailed information regarding the No.
1 
                          publication, and I plan to leave this entirely
in 
                          your hands, our suggestion was made to get the

                          wheels rolling as soon as possible and to assist

                          you in accomplishing that purpose if we could.

 
                                         I think that your suggestion of
using 
                          the proceeds as a revolving fund has many desirable

                          features. It may be advisable, however, to 
                          incorporate this in a general revolving fund for

                          all publications. This is something I would have

                          to give further thought to before I would care
to 
                          make a commitment either way on the matter. 
 
                                                        Very sincerely yours,

          Senator Walctt, Mr. Bell, and the rest of us had a 
lone discssion on the msbjeot of Delta publications at Delta this 
Sumer , 
 
          In the first place, Mr. Carpenter of DuPont made a special 
eontrlbution of $500(T) for this purpose. M record of the amount 
has beoe loaned to Professor Rowan. hww*e I mut p by recolleotion. 
I wonder if this was ever collected? 
 
          It was agreed among us at Delta that there should be a 
Delta Valletin series, each of which wou  include the important 
developments since the last ms published. This being No. 1, it 
would include everything we have r&4 to publiuh by this date. 
Rouhbau will write No. 1 this winter. He canout push it a    faster 
than that because this fall's data must be inoerporated. It you need 
a list of contents, Hoohbaum can farish an approximate one at any 
time. 
 
          There remain a lot of detailed question* such as whether to 
charge for distribution over ad above a picked list, details of make- 
up, etc. Unless it conflicts with your other plans, I would sugest 
eharging and using the proeee as a revolving fund.

Dear Aldos 
 
            In your report on the Delta Duck Project 
you suggested the desirability of having some 
publications released this fall or winter. 
 
            I have called this to the attention of 
Senator Walcott and he has asked me to request that 
you push the publicatim of some of the leaflets as 
rapidly as possible; also that you give us some 
estimates on the cost of these items and the type 
of publication you think desirable. If possible it 
might be well to give us the title or at least the 
subject matter on which these bulletins should be 
released so that we can start a build-up prior to 
their actual publication. We could arrange to have 
them printed or perhaps you have some other suggestion. 
 
                                 Very sincerely yours, 
 
 
 
                                 J. Paul Miller,

Dear Paul- 
 
          Hochbsum has showe4 me Miss sos letter of October I which 
gives the Delta balanss to that 4ate. 
 
          Senator Walcott has probably tol4 you that while he was at 
Delta, botulism broke out on a nearby marsh. This was a heaven-sat 
opprltuity to test the hypotheeis that the isturbed sex ratio In  uaks 
is due to the differential Impact of botuliem on the hens and youug whiOh

are still In the small ponds at that season, and the drakes whish have 
already reained their feathers and are on big water. Our lcal opidadeo, 
however, soon ie.4 out, hence we wrote the Biolegical Surve to please 
pro**vo botulism-.klled ducks on their refuges so we could sex and ago 
them. 
 
          Yeo understaMd, no doubt, that most of the Survq sen do not 
understand aging by the loeafa. 
 
          Hohboum now has word that the Bee River Refuge in Utah has 30 
ducks preserved for us, and other refue keepers my report later. To go 
through these birds will require unanticipatod travel. Soobbaum has auk-

aged his ex   se well and would have been in the black, bat I anticipate

that if he ha  to visit m   refe he       m na   dicit. He will advise 
you later about this, and we will make the trip anyhow whether we ea get

wepense for it or Aot, because the oppeilwity is too good to Ms.. 
 
          With beet regards, 
 
                                     Sincerely yours,,

Dear Professor Leopold: 
 
       The mail has just come in with your letters of October 14 and 
copies from Mr. Miller and Dormeus. I mut confess that I am a bit 
sheepisb about the birds with lead poisoning and not havin7 passed 
word along regarding them before this. You will remember that Mr. Bell 
mentioned his interest in lead poisoning when he was here in August 
After you left we had a small residue of mallards which we had kept over

pendind a deoission on the breeding experiment. Havini let these plans 
pass by we were going to band and release the birds when Ed sugaested 
thet we feed them some lead.Just to see what happened* He was interested

in seeing how many shots would kill a bird and I welcomed the chance 
to see if hens might fall off quicker then drakes. 
       On August 71 the following doses of standard # 6 lead shot 
were given to P2 mallards*

       The shot was given the birds by depressing the tongue and forcing

the shot down the gullett.  They were then allowed to swallow and then 
the tongue agon depremsed.the birds turned upside down and shaken to 
make oertain the shot was with theo for good. All birds were banded. 
They were placed in two of the house pens and giveb the same care end 
food as all the other afm captive birds. 
       Among the juvenilestwo of the hens (both birds with 5 shot) were 
very weak and had lost considerabb weight by September S. One of these 
birds died September 19 and at that date was little more than skin and 
bonesalthough until the last it fed as heartily as the rest of the birds.

 
  

					
				
				
-a. 
 
 
The other female recovered and by September 30 had repined normal 
weight. None of the other Juveniles showed any signs of heving been 
affected by the lead. 
       Among the four adults the three drskesotwo with three shot and 
one with two shot. began losing weight within a few dpy after they had 
received the shot. One diedelx days after the dose of two shota second 
died 18 dayeafter a dose of thvee qnd the third 39 days af ter the dose.

All three lost weight until they were nothing but qkin and boneseyet they

all fed well and had had heavy meals before they died. The adult hen 
with three shot remained heavy. Pnd Is still alive. 
       On September 70 all the remaining birdsall in good oondition, 
were given an alditional d6se of shot. light birds werm given 15 # shot 
each and ten were given eikht shot. Todate none of these birds have 
shown any signs of having Seen affected by the second dose. 
       The whole thing began more or less as a Sunday afternoon affair 
and I was aware that similar tests had been conducted elsewhere. I weloemed

the opportunity to see the effects of lead poisoning at first hand and 
believed that perhaps something might come up that might be well worthwhile

talkinw over this winter for future plans. "evertheless I did consider

the whole thing very lightlyalthough everything with the birds has been 
done very carefully, and was waiting to see what happened to the birds 
after the second dose before bringing the matter up. 
       I have no hunches as to why the three adult drakes dropped off one

two three while the rest of the birds took It in good shape. Perhaps 
it is worth thinking about~for I don't b-lIeve anyone has mLrked the effects

of lead on different age classes. I shall keep you in touch any other point

of interest that may develop. 
       Mr. Dell brings his guests to the duck house for one morning each

visit and I am afraid the account of the leaded birds was a bit flowered

on the trip through with Mr. du Pont.   The mov-ment of the wests 
through here is so much a sleight of hand affair that "e seldom know

who ts shooting. Mr. $all had as down for a talk with Mr. Du Pont, 
howevervand I had intended mentioning this for, if I am not wrong,he 
made the donation for the bulletin.. 
 
 
                                    Sincerely.

                                     I am enclosing a copy of a letter 
                          which I have received from Mr. Doremus. It is 
                          self-explanatory and I think indicates the 
                          interest of some of our Board of Trustees in the

                          work being conducted at Delta. If you can give

                          him say information as to the progress of hte mrk

                          up there in this particular line in vhich he is

                       I interested, I think that a personal letter from

                          you to him should be in order. 
 
                                      I am most anxious to visit the Delta

                          Station and hope that I will have the opportunity

                          in the relatively near future.

  Dear Sir: 
 
                  Mr. Eugene du Pont was in the 
    office this A. M. and reported on a visit he 
    recently made to the Delta Station with Mr. James 
    Bell. Mr. du Pont was quite impressed with the 
    several research activities at the Station. He 
    particularly mentioned the studies being jade of 
    ducks being fed No. 6 shot. Hope sometime before 
    long that we will get a bulletin giving us to date 
    data on findings at Delta. 
 
                  I like your monthly report idea, it 
    is a step in the right direction. 
 
                             Yours very truly,

worries me is whether you can finish the year without a 
mower* pinch, hmae I have &akd the Institute to gve you 
the bal&ace. as thq stand on their books. I have kept no 
books, leaving it to y  to keep within your totals. 
 
          After you have Mise Cee's balance I would s_ 
gest you cast up your liabilities and let me know whether 
there is any epecial action necess.ary 
 
          Arthur wa here yesterd  an  is getting ready

the Delta allotment is running pretty elose to the line. The 
transfer* whih she has mae as between sub-allotments are 
sensible and satisfactory. Mq I ask that she send ochbauw

including salaries so that he can plan the remander of the

73eer ProfessOr Leopold: 
 
       1'e are coming close tb the end o" our expense money and in 
submitting accounts I wTnt to be certain that I do not go over. For 
this reasonI am providing a brief sumrr-ry as I submit the accounts 
for September. 
 
       Of the $900.CO aet aside for my travel and hatchery running 
expenses,, "?4.44 had been consumed by September let. My expenses for

August, submitted September let were 456.60. These have been received, 
leaving now $8.96 of the originl *900.00   . This is not as bad as 
it sounds, for '010.00 of the J674.44 mentioned above went to the 
Petty Cash fund in August. I have drawn on this ancount during the 
last two months but have also deposited the exchange surplus from 
the July and August expense checks (but not pay checks) with the 
Petty Cash fund. In addition to this Mr. Miller has sent a chech of 
$44.95 to replenisb this fund. This with the exchange from expense 
checks brings the Petty Cash fund to h138.00 after payment of 
September expenses, 
 
       All September needs for the hAtcheryetc. hav- been paid out 
of the Petty Cash fund. As my figures show that this fund is all 
that remains of the expense money I would. like to ask if travel expense,

which I am submitting Ps usual should not be withdrawn from this 
fund. Thr-re will be another lerge feed billabout $70.oo that must 
be p*d7in ctsh from this fuAd as well as smaller items before the 
year is over. Still, I think it will cover travel and other e-penses 
until the end of the year. 
 
       I have sent a copy of budget accnunts es I have been able 
to check them to youx end to the office in Washinzton with my 
expense account last month. I have not sent a copy of this letter 
to Mr. Miller for he probably has not had time to go into our accounts 
and I do not want to bother him until we went over it together. 
 
                                   Sincerely,

       We are coming olose tb the end of our expense money and in 
submitting ocounts I want to be certain that I do not go over. For 
this reason I am providing a brief susary as I submit the accounts 
for September. 
       Of the $900.00 net aside for my travel and hatchery running 
expenses,$ 834.44 had been eonsumed b September lst. My expenses for 
August, submitted September lst were 156.60. These have been received, 
leaving nov $8.96 of the Qriginel $900.00  . This is not as bad as 
it sounds, for $10.00 of the $874.44 mentioned above went to the 
Petty Cash fund in August. I have drawn on this aeeount during the 
last two months but have also deposited the exohange surplus from 
the July and August expense ohecks (but not pay checks) with the 
Petty Cash fund. In addition to this Mr. Milleot has sent a ohech of 
$44.95 to replenish this fund. This with the exchange from xpensoe 
checks brings the  etty 0ash fund to 4135.00 after payment of 
September expenses. 
       All September needs for the hatchery.eto. have been paid out 
of the Petty Cash fund. As my figures show that this fund is all

which I am submitting as usual should not be withdrawn from this

Mr. J. Paul Miller

Dear Paul 
 
          In your round of Institute projects I hop, you will oover 
the Delta station. 
 
          I have two reasons for recomending this. One obvious reason 
Is that Pirnie and I want you to see the Delta work. 
 
          ,he other is that an adustment in Hoohbaun'e salary Is, I 
think, due. PittRan--Robertson is begining to hire his assistRnts out 
from under him at salaries as high as his own ($1600). 1 consider him 
as good as most U.S.B.S. unit leaders who are getting much more, and 
also moist ittman-iobertson project leaders getting $ý2t4. 
 
          I purposely recommended a low initial splary for Voohbaun 
because I do not approve of the breau practice of high initial rates, 
followed by no firings and no raises for good work. 
 
          B the same token I feel obligated to raise Roohblum as soon 
as *Delta Bulletin No. 1" is in press, which will be sometime before

spring. 
 
          Fochbaum has low housing expense at Delta, but other living 
costs are high and the necessity of moving south for the winter entails 
costs. 
 
          It is conceivable, of course, that we should hold the Delta 
directorship down to 100 and be resigned to frequent shifts. However# 
the available replacements san all get $2400 under Pittman-Robertso, 
so we are really in competition with ourselves. 
 
          I am not sending copies of this to either Pirnie, Walcott, 
or Mr. Bell, as this might tie your hands. Will await your opinion 
after you have seen the works. 
 
                                  Sincerely yours, 
 
 
                                       Aldo Leopold

P. S. Audubon Society paid my trip to New York. Mr. Dodge bought my 
plaUe ticket back, and I suspect charged it to himself. The ticke 
cost $ý1.25 (see attached). Senator Walcott asked me to rewind the

Institute of this, so that the necessary bookkeeping adjustments 
could be mdoe.

       The season ornened Monday and you shorild hpve sepn the array 
of poor little ducks end old flightlise females. The weather is 
as warm as July,there are clenr skies and no wind and the mallards 
are feeding under a full moon on the stubble fields. Except a few 
birds out on the lVrger bays most of the birds are on the lake and 
the only birds shot were late-hatched young and flightless fenales 
taken by jumping along the edge of the marsh. We have three more 
good clubs lined up this year and I hope they can line up some ducks 
before the season closes. 
 
       I was very sorry that Dr. Cole was unable to come up. We must 
try to get him up when you come again. 
 
       The enclosed is the payroll for the month of September. 
 
       The lodge ooened with the first day and there have been four 
or vive shooters here all week. Mr. Bell comes Monday and will 
probably be here for several weeks unless this summer weather continues.

 
 
Yours sincerely,

Dear Professor Leopold: 
 
 
       Thank you for the papers and the duck pictures. I forgot 
to mention how much I appreciated your notes on the recent meeting. 
Enjoyed the note regarding the banding club but am afraid the 
banner would be ruled out in Canada. 
 
       Mr. Bell decided to open the lodge inspite of war and 
low water. The season opens Monday and we have a number of 
clubs lined up for examinations. 
 
       I agree with you regarding the budget. I hope Art can take 
Peter for I do want tim to haye the esperience and I know Art 
would get a good deal out of Peter. 
 
       Ralph and Lyle have sent in their travel expenses for their 
trios to r.nd from Delta and I am enclosing their accounts, You 
will remember $1oo.00 was set aside in the budget for student 
trevellink exrenses° 
 
       You received a copy of Mr. W.B.Bell's second letter. 
Seems to make quite a difference who writes and I1' glad 
you sent them your mote.

 Dear Professor Leonold: 
 
           Pe have been up to our ears disinfecting,oleaning the 
 duck houde, pullinq in traps -knd resing the last o' the ducks 
 that I have not been able to qet at this mechine or to town with 
 letters. 
           I had gathered from your earlier correspondenee with Mort 
 Palmer that the payroll was to be sent directly to Washington from 
 now on and did not mean to bn' premature in making this change. I am 
 enclosing the August exnense account and our sccounting of the petty 
 cash fund. 
           As you will see fror the Pnclosed summary of expendit~ree 
 for this yepr 1-, bave underestimated our needs for the rest of the 
 year. Peter's pay ends the last of September. In making ott our budget 
 last ypar. Peter's plan for winter -ork in the Stbaes started Oct.lst 
 and we ha/d not planned to carry him beyond this. Yr. Bell has just 
 writtpn th~the American Yuseum cannot take P-teir this year and with 
 conditions so unsettled it looks as though he will not get away this 
 fýll. I would liko to have him with me on the bag taDlly and with

 his car Pnd mine together it -ould be possible to examine mpny more 
 birds this fall, vnd tie uco the three yper§ bag tally with a good

 finish. Would it be to.- much to ask the Institute for $200.00 for 
 Peter for October §nd November and for ýlO0.00 travel money?
If that 
 sound- too'big wrould $100.00 for October and ý50.'ý0 for
travel be 
 too rmuch?. Oth-rwise he will have to vuide and have little timre for 
 anything else. 
 
          I hnve been v ry disaooointed with our success with sick 
birds Pt Netley. When we return- the 14th conditions had chang-ed 
with cold weather Fnd th re were almost no recent deaths. Thr birds 
that had died the week before were so hard to find in the vegetatlon 
that 40 ww   the best we could do In the region of the severest out- 
breaks. We stayed three days but were able to look -it few birds. 
          Tom Yain hrd called o-f his crews thnt were coll cting the 
dead birds an, -,e hpd no help th'ere. He is out of money but I urged 
him to find enou7h* t- keepo one ýnn on pýtrol anl if warm
weather 
comes again we may have some birds. 
 
  

					
				
				
 
 
 
 
 
 
 
 
 
        The enclos d ittler fwm Dr. Bellidoes not offer much in 
th- way of help but I err, writing to Low end Y-neryand may be able 
to do something down th-rP.

 Dear Dr. Oabrielpon: 
 
       Mr. Aldo Leopold has written to you of our interest in 
examining sex and age ratios of waterfowl losses in outbreaks of 
botulism.    Within the last week there has been one serious outbreak 
in Manitoba and several in Saskatchewan. Mrny birds are dying on 
these areas in spite of rescue efforts and, beoause of the 
simultaneous ocourrence and the spread of the disease over a 
period of weeks, it is quite impossible to study more than one or 
two areas during the period of heaviest losses. 
       In order that we may examine as many birds -s possible I have 
made arrang'ements here and in Saskatchewan to have dead birds peced 
in drums of formalin and held until I con reach the area. At the 
Netley marsh in southern Manitoba we have found tlhis to be very 
setisfactory and the workers have found it little additional labor 
to save the birds for us in this way. We are using 70 and 45 gallon 
gae and oil drums Pnd water barrels, preserving the birds in a 10% 
solution of 40% formalin which is easily obtainable throughout the 
wheat country. A stronger solution, 15 or p00, is destrable where 
decomposition has started before the birds Pre taken. 
       We wish to examine as many birds in as many different areas 
this season and it would be possible to visit areas in northern 
Minnesota and North Dakota.   In the event of any outbreaks of 
disease within the radius of operations of Refuge Managers, I wonder 
if it would be possible to have birds saved for u- in drums of 
formalin. We will visit the areas as soon as possible in September 
and will proprly dispose of the birds after they have been examined. 
Ohould this saving of birds be impracticable, I would appreciate 
being notified of any serious outbreaks in North Dakota in order 
that I may run down from Delta 
 
       Thankin# you for your interest and cooperation, I am, 
 
                                Tours sincerely

               Doer Mrs ?!oahba~un 
 
                    Aldo Leopold has sdvised us of the work you are doing
on 
               sex ratio in ducks snd states you will see to obtain a larger

               number of speoimens for sisitios thas have been available

               to date if your data is to be of statistical signifioeso.

               Sino* the botulism outbreaks which occur on several federally

               owned refuges offer an une"olled opportuity for obtalning

               specimens which could be used in this connection, Mr. Leopold

               requested the assistance of the Service in colleoting ducks,

               partioularly deep water specimens. for subsequent examination

               by a mmber of the Station staff. 
 
                    Unfortunately your need for assistnceo in this connection

               somes to our atteation sear the end of the season when ex-

               oeesive losses are likely to occur. Nevertheless we have is-

               structed refuge mgers wh are in a position to coop*rate In

               this venture to preserve dea  spoclne s brought in from the

               marsh without attempting say soloeties of sex or age classes.

               Since Mr. Leopold advises you will need large numbers of ducks,

               no limit has been placod os the quantities to be oolleoted
em

               of several species may be obtained for examination. On the

Dear M. D. 
 
       Profes-or Leopold has sent mo a copy of his notes 
to you on the recent Delta meesting and th-ro it no need for 
me to m into dptail about this. We were all sorry that you could 
not be with us. It wap a very sccessful meetinp Pnd -e 
reached many understandings that will make for a 1tronger 
group. Mr. bell was somewlat concerned over    -nnetts letter 
concerning the cloacal study, but I assures him that it was a thre e 
year work and not in competition with our own efforts. 
 
       The mallards from the same lot as yours flew at 8 ý weeks 
*nd their wings were hard a week later. The earlier birds 
flew at seven weeks and the only reason I can give for the 
slower development Is that we had to keep them in the house pen 
until they were fully feathered. Several birds of this age 
group were placed in the flying pen with the older birds and 
were so harassed that they are still without feathers. We 
should have built ambmm another outside pen and are planning 
to have more pen facilities next year. 
 
       In working over the material for the bulletin we would like 
to have the Omn" skin collection of young birds. We spoke 
of thie last sprinp and wonder if it would be possible 'or you 
to have these shippýd up. T an enclosing the filed numbers of 
the specimens we would like. 
 
       Reve been tryinz to work over the birdg lopt at aetley 
 in the recent outbreak of botulism. The cold spell of the last 
 week has held down the deaths considerably and,*hile I am glad 
 the birds are not dying,' am qutte disapoianted in not being 
 able tn oxamine the age *nd sex ratios of a large number of 
 bird@. 
 
       Ralph left a week early and #aid hb would report to you 
 at the Sanctuary. He did a good job with his skinning and 
 with everything else he was told to do,althougb ,his interests 
 did not mp43 to go far beyond the pkin-inw table.  I sm glad 
 we were able to h1v- him with us and I think he got a vond deal 
 out of being bere. 
        I hope to have the bulletin msttertal in shape by the time 
 I Omm-n*s   move down this fall. I am perticulprly anxious 
 to io over the mvtortal on age and sex identificetion with you, 
 and I wonder if you would -find time to work up a resume of the 
 tail character that I might- quote. You will remember that you

suggested that you might to this *the review in your tVeý1. boing

rather brief. Ineidentally, this certainly comes In ahndy with 
the dead birds at "s-tley -nd saves muEch bndltng of badly decomposed

birds. 
       ,1r. Bell hne made the suweestion that Peter spend the 
winter months wict Jaques at the American Museum   He will 
make a donation to the museum mnd they will pay  otor a small 
salary that will be enough to keep him over the winter. I think 
it is a good idea and wisk I could spend a couple of months with hin 
mye~elf. 
 
       WateL in very low here but we have ruffered no losses from 
disease at  elta. Runter's will have a hard time gzttitt  to 
th- beet rhootinc points tVis fell and, with fewer shooters because 
of the warwe are looking forward to a such smaller kill this 
year. 
 
 
Yours sincerely.

Dear Mr. Bell: 
 
          It has meant a great deal to have you and Renator Waloott 
with us for a discussion of our work and I want you to know how muob 
we have appreciated your effortR in asking the meeting possible. I 
was glad to have the ppportunity of meeting Dr. %owan and am looking 
forward to future meetings and correspondenre with him in relation 
to our work at Delta. Pbould the opoortunity Dopsent itself we shall 
make a try for crows for him, althouch the outlook at present ts not 
hopeful. 
          We are all v-ry much pleased with your suggestions that 
Peter find work as apprentice at the American Museum. I am sure that 
he will fit in well there and that he will win much inatructU6n and 
inspiration from Vr. Jaques and others as well as from younger fellows 
who are following miob the same course no his. 
          I know that you must have been distumbed by the low water 
at Delta. Our pgue has shown a five-mnoh drip sinoe early July and, 
with the loe water,milfoil hap eloaped many of the bays. Too will be 
heartened to know, however, that we havy had little difficulty in 
rapching deep water in the region of Bell's -oint and the tule islands 
to the south and east from Cooke Creek.

     Senator Walcott in writing a report on the decisions reached 
 
during these discussions. His report will govern. I am writing this 
 
supplementary memo to facilitate his report, and to notify Pirnie so 
 
that he may ratify or comment on the actions taken. 
 
     Canadian Member of Advisory Board. Professor William Rown of 
 
the University of Alberta was asked to accept the vacant place on the 
 
board, and accepted. I am sending him my recent files so he can catch 
 
up on recent questions. 
 
     Form of Publication. Neither the Institute nor Mr. Bell have any 
 
objection to the expense of printing short bulletins which may be necessary

 
to protect research findings in need of prompt publication. It was finally

 
agreed, therefore, to publish Delta findings in a Delta Bulletin series,

 
which will be printed and distributed by the Institute office in Washington.

 
Bulletin No. 1 will be brought out this fall or winter, and will probably

 
include (a) the cloacal method, (b) sex and age ratios and movements, 
 
(c) the Franklin ground squirrel study. 
 
     Hochbaum should notify the Institute, as soon as he can, of the approx-

 
imate length and the mmber and kind of illustrations, so that the Institute

 
can determine the sufficiency of Mr. Carpenter's $500 contribution. 
 
      The relation of invited workers to the Delta Bulletin is left open,

 
but it, is understood that if we want their findings of the bulletin, it

 
will be stipulated that they publish in it. 
 
     Future Program. It was decided to try spring trapping and banding 
 
 of canvasbacks at the marsh pen, using hatchery birds as decoys. 
 
  

					
				
				
 
-2- 
 
 
     It was decided to put the deepwater breeders in the marsh pens 
 
next spring to see if that will make them lay. If this is accomplished, 
 
Mr. Ward's accumulated techniques on hatchery practice will be completed

 
and can be published. 
 
     I did not press for a decision on the mallard deterioration project,

 
having developed some doubts in my own mind lest this overload the program.

 
Meanwhile Hawkins in Illinois has a chance to go ahead with it. If there

 
is no objection, I will encourage hih to do so. An Illinois project will

 
be all to the good, whether or no Delta eventually tackles the problem. 
 
Hochbaum proposes that the U.S.B.S. might be able and willing to undertake

 
the problem, perhaps using Delta as one of a number of stations. 
 
     Sexing and &     Disease-killed Ducks. The heavy mortality at the

 
Nettley marsh on Lake Winnipeg gives Hochbaum an exceptional opportunity

 
to test his hypothesis that disease operates differentially against females

 
and young of deepwater species. He has decided to spend a week tallying 
 
disease-killed birds; Tom Main is pickling the dead birds found by his crews;

 
I have asked Gabrielson to pickle the dead birds from any outbreak which

 
may occur on his refuges. 
 
     Disease Research. The existing publications on botulism seem to fall

 
short of explaining the observed losses. Some further research is badly 
 
needed, particularly in Canada, but our present staff is not qualified to

 
do the work. Senator Walcott is taking up this question with Gabrielson.

 
     Invited Workers. Selected individuals or institutions who wish to do

 
work which fits into the Delta program are to be invited to work at Delta.

 
Selections are to be made by or through Hochbaum. Mr. Bell is arranging 
 
quarters large enough for both our own staff and possible invited workers.

 
For discussion of publications by invited workers, see "Form of Publication."

 Dear Aldo: 
 
       Ever since I got back from the Delta trip it has been 
 one rush after another, in spite of having only two graduate 
 students on had and no 9%eral summer session. First it was the 
 little ducks from Delta eggs, hatching just before my return. 
 These are now 71 weeks old, and from Albert's report, it is 
 about a tie as to development; perhaps better feeding and less 
 crowding here offsetting *he longer days at Delta. 't is just 
 a small test of the sort we want to do on larger scale, and 
 must do týf the mallard study is to go ahead. 
 
       With Mort resigning, and Senator Walcott planning on 
 a trip to Delta, I did not file a report; nor have I had time 
 to make prints of the negatives, except the squirrel egg-eating 
 for Lyle. I am sending Mr. Bell a couple of Kodachromes to 
 indicate how I appreciate the bab* ducks.   But I especially 
 gegret being slow in replying as to the Delta August meeting 
 and on the matter of publications. 
 
       First, as you may have guessed, I cannot finance a trip 
 to Delta, and do not think my presence of paramount importance, 
 as much as I should like to be there and to have a chance to 
 continue discussion of the new researches in mallards, new 
 personnel, etc. Please express my regrets at having to be 
 absent. I feel the Institute should pay your expenses,' 
 
      Next, the matter of publications: Where it seems urgent, 
as in the case of Albert's article on sex determination in 
young ducks b* the vent examination, I certainly would approve of 
a rush into print, in separqte article; but I do not yet feel 
the Delta report should be scattered UNLESS necessary to do so. 
I like the combined report put out by one ageacy, with due 
attention to uniformity, illustrations, etc.; which of course 
is a better wry of crediting sponsoring individuals or organizations. 
I am quite sure Albert and I can agree on use of material.***** 
Doesdht the Senatorts letter indicate a belief that you refer to 
publishing piece-meal in the Institute's publication rather than 
in various ones? Albert said nothing, that I recall, on the 
matter of giving up the idea of the Delta bulletin or report 
series.    Shall be glad to hear further on this; and in the 
meantime &o not consider my attitude as closed or final. 
 
      Am much interested a long-time, well-planned mallard study; 
 but do not think the set-up is yet at the point where we can 
 expect to finance a geneticist without handicapping the new 
 program for larger and better rearing and holding of the 
 experimental ducks. Dont think we all agree on what we mean 
 by deterioration or "scrubs". And how meny years do we breed 
 a stock before we call it "pure"? Not less than 10-years 
 will be needed for such a program; but there is much we need yet 
 in the 3 to 5 year lob of marsh investization and 'lumaze a 
 
 
etc. Would like long visit with you on this. Hastily, MIW V\1J'/

          So doubt ym are worrie4 about the sme thin that I m# 
n   3y reimurseent for ths extra trip. We can't take it out 
of the irdstin Delta fund, for Albert has that bmfdeted dw 
pretty closely. Unless, therefore, Senator Wnloott vobmteors to 
handle It from Wa   nagon, there will probably be no reimbursement. 
          I feel that I should o nevertheless, bet I will hardly 
blaze you If you feel you cant make it. 
          Before I meet Senator Walcott I would like to know your 
attitude on the matter of publioation dsaoussed in nq reprt, alsS 
you  attitude on the possible future mallard projest. If you are 
not there to speak for yourself, I would like to speak for both of

 Dear Alberts 
 
          I've been to see Leon COle about the maazd .VoexL&t,, and he

 has made some valuable omnts. 
 
          firt  of all, we mast not think of deterioration as aed 1W 
 environment vs. genetima change, nor of mallards as sharply      b or pare.

 
          Deterioration is the             Of variants due to withdrawing

natural selection and substituting arti *ial seleetion, conscious or umoo-

scieus.    e practioal qaestion is to determine: 
 
          1. The         of deterioration in ooanfinant, with and without

             selection. 
 
          P. The git of detorioration in wild survival (by banding). 
 
          Our exerimental proeaeue is O.K., 'but Dr. Cole has made some 
elaboreations.  on-migratory mallards should be subjected to endocrie tests

as well as banding tests. lint generation wilds should be subjected to 
ba    g                                      lests Ia wel as at eight weeks.
This 
is to seregte          asval 
 
          He agrees that a geneticist-endocinologist should be added to the

Delta staff (someone like Niek (hathbert, who is an ornithologist as well),

and that Carngie Institute might be Interested. 
 
          I urged that he take a look at Delta. Re is just leaving for his

vacation (address Qrdon, Is..) and might drive up to Delta about September
10. 
Mrs. Cole and his son Rwsrd will be along. If yea  an quarter them at some

ottage sad if a few Lqs' visit at that time would be soavensiont you might

write him at Gordon. 
 
          I haven't heard further from Fred Walcott but I an still expecting

to come up with him, and I hope Miles, about Augast 19. aven' t heard from

Miles but   sending him this letter.

Dear Professor "'eopold: 
 
 
       I am qld to hear that Senator Walcott will be able to 
visit Delta and the 18th will be fine for us here. I do hope 
this will not cut into your work too much but it will be 
great to have you with up again. I hevp inquired about the 
geese in James Bay and will let the Senator know about the poppibilib"

of scein£' them Ps soon as I can. It is quite a diptance over there.

however,and more or less off the regular flight lanes and I am 
afraid such a trip would be very expensive. 
 
       The check for the cash account has come tlhrough and I want 
to thank you for making this pospible. It will solve a lot of 
our troubles. I shall keep accounts as Mort has suggested. I shall 
also deposit all exchange surplus from my expense account with 
this which will take care of that loose end. 
 
       Spent t-o days rith Cartwright at the Netley marsh where 
am botulism is killing a good many birds, Ee has things well in 
hand th-re,diiecting his efforts towards kepping the birds away 
from the infected areas which are rather restricted. There will be 
considerable loss,however, end rather than burning the birds this 
year as they did last, he is putting them in drums of formalin. 
hk5will let us make our examinations of sge and sex ratios in two 
or three one-day visits.

                        Dear Aldo: 
 
                                         I am attaching herewith two checks--

                        $150.00 of this is Al Hochbaum's salary check for
July 
                        and the other $100.00 is fcr Al to open a petty cash

                        account at Delta to be checked out by him for current

                        items. 
 
                                         Do you want us to keep mailing these

                        salary checks to you? It seems like an unnecessarily

                        complicated system. We can make these checks payable

                        directly to the individuals concerned and mail them
to 
                        them at Delta without putting you to the trouble
of 
                        handling them in any way. Unless you have some objection

                        to this I wish you would tell us. 
 
                                         In the matter of the petty cashaccount

                        there need be no complicated system of accounting.
I do 
                        feel, however, that it is desirable for the protection

                        of everyone involved that vouchers for all payments
be 
                        submitted with a simple accounting of expenditures
at 
                        the end of each month. This will enable us to make

                        reimbursements of this account every month as well.

 
                                         A check to cover the balance of
the 
                        July salaries will be forthcoming shortly.

Dear Professor 'eopold: 
 
 
       Thank you for the reminder on the letter to %ennett. As you 
had recommended me for the job I felt that I should at least 
invstivpte the outlook for th- future of work here under war 
conditions before giving an answer. 
 
       The R.C.A.F. hpve been herp spvrael times since you left 
and their plans for using the mprph for bombing prpctiap seem 
quite definite.   They will put their targets on the point south 
of the lodge. 
       Last week I loaned Lyle end Peter to Mr. Cprtwright for two 
days to make a survey of nest destruction in heyfields at the Netl*ey 
marsh on Lake Winnipeg. Mr. Cartwright is working with the Government 
in an effort to stop spring burninq end early cutting on marsh 
haylands end as the work he is doing at Netley will have bearing 
on hey permits for all mprshlpnde in initoba I felt juptified 
in cooperating with him on this. He hasp just phoned me this morning 
to say that another outbreak of disease is beginning on the south 
shore of Lake Winnipeg and I am going over for a day or two to out- 
line the job of taking az and sex rptios.end to help with the salvage 
work. 
       We had Earl Mitchell with us for t-n dpys. I was very much 
impressed with his interest and abilities and wps sorry that I had 
not become better acquainted with him in Madison. As one of 
SwensonAs students he would like to come up h~re on his own to 
do his thesis work end will if Swpnson is agreeable. 
 
       Have spent the lest two deye makin7 drives for young ducks 
but find the greatest difficulty ta is to keep the ducks ahead 
of the d&ive and out of the reeds where they hide. We have not 
taken many birds as yet but have learned enough to hope for some 
good catches, 
       Thsnk you for the checks for the boys and for my own expense

       It is the first of August and we do not hpvp the skins 
from the sanctuary. It is possible that Miles mpy not have understood 
and I am asting for them again.

Dear Dr. Bonnitt : 
 
       loet me thank you for your letter concerning the position 
with the University of Missouri. I shall,of course, kep this 
matter in confidenee. 
       It so happens that I am now engaged in developing a 
waterfowl research program at the Delta Varshes in Southern 
Manitoba. Our pr.ojet has been planned to oarry through for 
five years and in fairnese to the sponsers and to myseelf I fl 
obliged to follow this to coupletion. 
       Your letter has come with very unsettled times here for 
the war promises to upset many plans and promreas. Before enswering 
I have gone over rather carefully the outlook tor alien workers 
engaged in such problems as ours. We may expect our work to go on 
as usual,I find,with no promised interruptions except bombing 
practice in our best duck marsh. 
       I will see it through herebut lot me thank you for letting 
me know of this work. Your Missouri organization appeplp to me 
Very much. 
       We have had a number of students working with waterfowl 
problems as visitors this summer end I would like to take this 
opportunity to         know that we would welcome any of your 
group next year. A- 
 
                           Sincerely yours,

                                        Delta Duck Station, 
                                             July 29, 1940. 
 
Mr. T.C. Main, General Manager, 
Ducks Unlimited (Canada), 
Winnipeg, Manitoba. 
 
Dear Mr. Main: 
 
      From July 23rd to July 26th we visited the Libau marsh to try and 
determine what effect local haying operations had upon duck nesting in 
that area. Excellent cooperation was given us by Mr. Art Anderson and 
other local people. (Fig. 1.) 
 
       During the three days spent in the area an attempt was made to 
 look at all of the nests IvMr, Anderson had found, and to systematically

 strip cruise sample areas of nesting cover of various types usually con-

 sidered good, average and poor nesting cover. A summary of data on the 
 nests examined is given in table 1. A discussion of the techniques, 
 observations and conclusions is here given. 
 
 
 
       It may be impossible in all cases to determine what species of duck

 certain nests represent, if they are too old or badly damaged by haying

 operations or predators. However, none of the 31 nests which we examined

 were beyond the stage of accurate species determination. Methods of 
 species determination are: 
 
                 1, Use of Known Down Samples. The nesting down of every

 species of duck has certain characteristics which distinguish it from all

 others. This is based mainly on size, shape, color and general appear- 
 ance of down feathers. By comparing the down found in the nest with 
 known down samples collected at the Delta Duck Station most of the nests

 could be identified to species. 
 
                  2. Size,_Sha.e and Color o    g  Fragments. Since the 
  addition of down to the nest is done during or just before incubation,

  nests with incomplete clutches seldom have much down, Thus the technique

  of down identification in determination of species works only in completed

  clutches. In cases where incompleted clutches were destroyed, the species

  was determined by the color, size and shape of remaining shell fragments.

 
  2. Distinguishing Between 1940 Nests and Nests of Previous Years 
 
        In addition to the 31 new nests examined, four nests of previous

  years were found. These nests were distinguished from nests of the year

  by: 
                  16 l oBung. Spring fires burned over a great deal of 
  the nesting cover in the Libau marshes in 1940. Egg shells and membranes

  of old nests were in most places scorched and easily distinguished from

  those of 'ew nests. 
 
  

					
				
				
 
 
 
 
 
 
-2- 
 
 
                 2. Texture of Shells. Exposure causes old shells to 
 become rough and porous in contrast to the brighter, smoother appearance

 of egg shells and shell fragments of newer nests. 
 
                 3. Y2Letation. In old nests grass tends to grow up 
 through the nesting cavity and the cavity becomes filled with dead vege-

 tation and soil. In new nests at this season of the year there would be

 little or no vegetation growing up through it. 
 
 3. Nest Destructionb.. Haying Operatiors 
 
       Of the 31 nests observed, only one was directly destroyed by haying

 operations. That was a teal nest which was tramped on by a horse. 
 (Fig.2.) However, the indirect causes of nest destruction by haying 
 operations are more severe, They can be conveniently classified as 
 follows: 
 
                 1. Desertion. Of the eight nests mowed over in haying 
 operations, three of them were deserted. The number of nests deserted 
 would be a great deal higher if hayirg operations were earlier because 
 ducks with incomplete clutches desert much more readily than those with

 complete clutches well along in incubation.  In our survoy most of the 
 nesting ducks were teal and shoveller which are maore tolerant of distur-

 bance than are the earlier mallard and pintaill 
 
                Although desertion anc predators cause failure in most 
cases where going nests were mowed over, in two instances ducks returned

to small islands of vegetation (Fig ,3.) which were left by the hay workers.

These were still incubating at the time of the survey. In one instance 
(Fig.4.) a teal nest was cut over clean and the duck returned to hatch 
all of her eggs. 
 
                 2. Predator Damage. In most nesting areas there usually

is a high percentage of nests taken by predators, in order to evaluate 
what percentage of predator damage could be directly attributed to haying

operations it is necessary to know when the nest was destroyed. The con-

dition and location of the remaining down and shell fragments gives a clue

to the time and nest was destroyed. By Gomparing the time that the nest 
was destroyed with the time of moving which was given us by Mr. Anderson

and other local people, we were able to determine, in al! cases except one,

whether the nest was taken by precators before or after moviing. 
 
                In the area studied the crow is by far the most serious 
predator. Of the 31 nests examined 9 of them were taken by crows and 
one was destroyed by a skunk. According to Mr. Anderson skunks are very 
scarce on account of the heavy trapping by the Indians. 
 
                Although we believe this report to be accurate over the 
small area intensively studied, we are not convinced that it gives suffic-

ient data to be statistically accurate over the whole Netley Marsh, A 
more comprehensive study should be made another season to gain a true pic-

ture of hayfield nesting losses, 
                                        Sincerely yours, 
                              (Signed) Peter Ward,

My dear Aldo: 
 
      I am delighted to have your note which arrived 
during my absence from home. I am eager to read your 
report on the Annual Inspection. It has not reached 
me as yet. 
 
     I think it is possible that Jim Bell will come 
up there with us. I am rather tightly dated up here 
until the 18th of August. I could fly on that date 
to Minneapolit, go direct to Winnipeg, and from there 
get in by the shortest route to Delta. I will close 
the matter up definitely if that is a satisfactory 
date for you, Mr. Hochboum and Mr. Pernie. 
 
     I am very eager to get up there and also to get 
down to Ohio to see what Hicks is doing. His work 
o~ht to be in a very interesting state at that time 
 
     Would there b* any chance of getting a hydroplane 
and going over * Hudson Bay. Perhaps it would be too 
early to get those flocks of blue geese that are 
supposed to be on James Bay in great quantities towards 
the end of the summer just before their flight southward. 
 
     I had a letter from Parnie saying that August 
would be as interesting a time as any. Would I beetoo 
late to see the best of it? Please be quite frank with 
me. I am quite determined to get up to Delta. If it 
would be better to go earlier I sholili do my best to 
change existing dates here. 
 
                           Sincerely yours, 
 
 
P.S. Your 1940 report on Delta Duck Stion ha0 3tst

      reached me. It is exceedingly interesting and makes 
      my mouth water for a personal inspection. I am sure that 
      it is going to be of great value to the Biological Survey 
      as well at to the authorities in Canada. 
 
           Will you give me some idea of the climate and what 
      clothes I should take with me. I always travel very 
      lightly. 
 
           I am very interested in what you say about "hangover"

      mallards. I experimented for several years with the 
      propogation of canvasback, some hand bred ones that L.R. 
      Joab brought down . I sent a pair to Norfolk, England 
      to Hugh Wormwold. 
 
           I like the idea of publishing our own 4oifrnAln 
         our findings as it becomes ready . We have a very 
  eCt,,i'-aluable maa~in Washington who can make good use of 
      the"a- ornals as we go along, and we shall get full 
(---credit for the work we are doing. The bulletin will 
      come later. 
 
           I think it a good idea that a petty cash fund be 
      given to Mr. Hockboum in order to avoid delays. A fund 
      of $100 will be sent at once.

                          to cover the June payroll for Ward, Sowls, Morrill,

                                    I an also attaching hereto Hoehbaum's

                          expense check in the amount of $126.55 for May.

 
                                    I have okayed Hoohbaum's expense account

                          for June and put it through for payment and will

                          forward the check to you as soon as it comes back

                          from Ted Doremus. 
 
                                    I appreciate very much your comments
in 
                          your letter of June 21st. It is nice of you to
say 
                          what you did and I appreciate it. It is unnecessary

                          for me to say that such sentiment is entirely 
                          mutual. Please don't count me completely out of

                          picture, however, as I do not intend to lose the

                          pleasant associations I have made in the past twelve

                          or fifteen years. 
 
                                    Looking forward to continued if unofficial

                          relationships, I am, as usual

          The peaulty for a pleasant field trip Is usually 
Spiled-up dsk upon one's retmrn. It is for this reason 
that I sent you aq Delta report without comnet. I now 
want to sq that I was ver mu    pleased with the way you and 
all the rest of the Delta grou are hanling thing  this year. 
Will you tell all of thea that I greatly apreciate their 
good work? 
 
          Thanks very snob for the len of the Jaqu  book. 
 
          Here are the Jue salary oheock for the others and 
you MA expense check. You raised the question of whether I 
should not reit expew e *heeks in the form of Canadin aoaw 
orders because of the favrable excange. I do not see how I 
could do this and still balance my books with the Institute. 
Since the prevailing tates at Delta are 1w, I think it fair 
enu    to continme to p  all tcounts in Aaerican dollars, 
but I &m  ing a cop  of this letter to Mort Palmer so that 
if he wishes to institute some other argemnts he can let 
me kw. I especially hope that he ca" take early action on 
the petty cash fund rwcoin. ed in the report.

Mr. Aldo Leopold 
Professor of Wildlife Management 
University of Wisconsin 
Madison, Wisconsin 
 
 
Dear Professor Leopold: 
 
 
       Wd all like your report end thank you for the time and 
trouble you heve put into this. It will help more than I can 
say in keeping things lined up for the rest pf the year. We will 
make our first release of captive birds this week and are getting 
things in shade for summer banding. Ducks Unlimited will send several 
fellows over during the summerone at a time besides the regular 
banderto become acquainted with age and seig techniquesetc. 
One of Swanson's students has expressed his desire to be here for 
a week in August for the same purpose. 
 
       !nclosed is the payroll for the month of July. I am a bit 
of an awkward position on this point for the boyp have not b-en paved 
for June. It is not that they are over-anxious about the money 
but they cannot pay their board and with things running on a narrow 
margin as they do here it mpkes it quite hard on Mrp. Ward. Avnin, 
Buster Hwkinson is badly in need of his money. 
 
        I certainly am glad that you could make the trip in the 
earlier period this year and I hope you can be with us for the 
spring flight next spring. By the waythose scat platforms you 
and Lyle put up are working great end we are getting more yp,for 
they provide the only place we have been able to get scats this year. 
 
 
Yours sincerely,

                                Aldo Leopold 
 
 
     This report is based on a visit at the station June 26 to July 4, 
 
and at Winnipeg July 5. I did not stop at St. Paul because Mr. Bell was 
 
out of town. 
 
 
                               (A) 1940 Work 
 
     This year's work is well organized and is noteworthy for the complete

 
teamwork among all the Delta personnel. 
 
     Research Projects. All of the research projects show good and some 
 
exceptional headway. The status of each is as follows: 
 
          Criteria of Sex and A   in Ducks. The discovery of cloacal 
 
extrusion as a means of sexing and aging live ducks is our biggest accomplish-

 
ment so far. The new technique has already spread far and wide. Its relia-

 
bility and its harmlessness to the bird are fully proved. It should be 
 
published this winter. 
 
          EE21oA7 of the Marsh. One more year should be added before publish-

 
ing this study of the arrival, courtship, nesting, brood behavior, ani summer

 
and fall movements of Delta ducks. 
 
          Identification of Dn YonA; Growth Curves. Now complete except 
 
for greenwing, baldpate, greater scaup, black duck, whistler, bufflehead.

 
None of these nest at Delta and the cooperators who promised eggs failed
to 
 
send them. All other gaps in the collection of skins will be filled by the

 
end of this nesting season. Will be ready for publication in the winter of
1941. 
 
          Nesting Study. 130 nests are being followed this year as against
100 
 
in 1939 and 25 in 1938. This is an excellent showing, especially since the

 
labor is carried "on the side" by the entire personnel. 
 
  

					
				
				
-2- 
 
 
          Ground Squirrel Study. Use of captive squirrels as experimental

 
stock has greatly speeded this project. Sowls will use it as a thesis and

 
will also Dublish this winter. 
 
          Sex and ke Ratios. This year all unhatched eggs from the hatchery

 
and all incubated eggs found in deserted or predator-nests are being sexed,

 
as well as all live birds and all deaths from the hatchery. 
 
               Should there be no shooting at Delta due to the war, the usual

 
bag tallies will be made on. outside shooting grounds. 
 
          Banding. Ducks Unlimited has offered to send a man to work at Delta

 
under the direction of the station. This should make it possible t6 give

 
undivided attention to trapping, and hence should enlarge the catch. It has

 
so far been impossible to match the hatchery releases with equal numbers
of 
 
wild releases. 
 
 
                                (B) New Proposals 
 
     Teaching at University of Manitoba. Professor Wardell of the Zoology

 
Department has asked Hochbaum, in cooperation with Dr. Cartwright of Ducks

 
Unlimited, to give a course next winter. 
 
     I talked this over with Professor Wardell and explained that because
of 
 
the time liabilities, Hochbaum could not take on the job of a formal course.

 
It would eat up more than half the year. Professor Wardell accepted the 
 
alternative proposal of a series of lectures, the purpose of which would
be 
 
to test the amount of interest in both students and faculty. 
 
     I told him that his students would be considered for the assistant 
 
positions at Delta, and that the Delta station is interested in developing

 
university participation in its work. I told him that if the university 
 
ultimately developed sufficiently along wildlife lines that it might even

 
(at some future time) take over the project. 
 
  

					
				
				
-3- 
 
 
     Work at Delta 2 Other Institutions. Half a dozen universities made 
 
overtures to Delta during the past year, indicating their desire to work

 
there. In many instances, though, the proposed work involved large-scale

 
collecting or disturbance of the marsh, and did not relate itself to the

 
Delta program. 
 
     It is now proposed that Delta select and invite particular men to 
 
work at Delta on projects supplementary to our own, provided they pay their

 
own way. 
 
     As invitation No. 1, it is proposed that Arthur S. Hawkins of the 
 
Illinois Natural History Survey be invited to work out criteria of incubation

 
in Delta ducks. He has already done this for several upland game species.

 
     Mr. Bell has proposed that Carnegie Institute might be willing to do

 
some kind of fundamental physiological research in conjunction with the 
 
Delta hatchery. As a first move I suggest that Hochbaum be authorized to

 
visit the Institute this winter, explain the Delta facilities, and get 
 
acquainted with the Carnegie program. It seems quite possible that we might

 
be able to interest Carnegie in one or both of the new projects discussed

 
in the next caption. 
 
 
                                (C) Tuture Projects 
 
     The hatchery is now being operated chiefly for the studies of young

 
ducklings (plumage, sex, age). This work will be completed by 1941. 
 
     Operation of the hatchery is expensive and laborious, but the hatchery

 
is one of the assets which no other research enterprise possesses. 
 
     I suggest the following possible future undertakings for consideration

 
and study. 
 
     ProAct #1 Domestication of Mallards. It is known that wild mallards

 
  

					
				
				
 
 
 
 
 
 
 
(like turkeys but unlike pheasants) deteriorate in captivity. It is not 
 
known why, i.e., mhether the deterioration is genetical due to admixture
of 
 
bad blood, or whether it is environmental and takes place even without 
 
admixture. 
 
     It is of great importance, both from the practical and scientific view-

 
points, to find out why and how deterioration occurs. 
 
     If deterioration is genetical, then official policies should be revised

 
to discourage the release of any but pure stocks, and to encourage the 
 
acquisition of such stocks by game farms. 
 
     If deterioration is environmental, then it is doubtful whether the 
 
release of artificially propagated ducks should be encouraged at all. 
 
     In either case, the extent of contamination of wild stocks should be

 
determined. 
 
     Present piblic policies reflect a lack of information on the nature
of 
 
deterioration. The U.S.B.S. and the states and provinces permit the release

 
of anything that quacks, even though Lincoln has shown that banding returns

 
from poor stock are negligible. On the other hand these same governmental

 
agencies often place obstacles in the way of propagant6a wishing to acquire

 
wild stocks. 
 
     Delta is a perfect location to study the changes that take place in
ducks 
 
in domestication. It offers a hatchery plant, wild stocks for comparisons,

 
and shot birds for comparisons. 
 
      It also offers "hangover" mallards which fail to migrate,
and which are 
 
either defective wild or impure wild mallards. Oartwright shipped some south

 
and they failed to return north. 
 
     Mallards are clearly the most important species in Ahich to study 
 
deterioration. 
 
 
- 4 - 
 
  

					
				
				
-5- 
 
 
     There are at least three possible testoof quality in propagated mallards:

 
          1. Banding returns after release to the wild (the best test). 
 
          2. Physical measurements (short bill, posture, large legs, etc.).

 
          3. Psychological tests by the use of the Long machine. 
 
     The first test has been applied at Delta on a small scale to first-

 
generation artificials of several species, with returns equal to the standard

 
for wild birds. The wild controls, however, have been insufficient in number,

 
due to difficulties of midsummer trapping. This test should be continued
on 
 
mallards on a larger scale, and the following new lots should be added for

 
comparison: 
 
          a. Deteriorated mallards (scrubs) 
 
          b. Second-generation pure mallards 
 
          c. Third-generation pure mallards 
 
          d. Descendants of "hangover" mallards, first generation.

 
     Physical and psychological tests should be ran on all lots. 
 
     Personnel and Z      nt. To undertake these tests, Delta will need:

 
(1) a revision of its hatchery plant to separate the various lots, (2) the

 
services of a geneticist, and (3) the services of field men to specialize

 
in trapping wild birds for controls. 
 
     Hochbaum and Ward are preparing estimates on plant changes. These will

 
not be expensive, and might possibly be made out of our regular funds. 
 
     A geneticist may be obtainable from the Carnegie laboratory at Cold
Springs 
 
Harbor. He should be an expert in statistical theory. 
 
     Trappers are already offered by Ducks Unlimited. 
 
     It is suggested that a parallel series of experiments might be run by

 
Pirnie at Kellogg Sanctuary, or by some state game farm. 
 
  

					
				
				
-6- 
 
 
      Experimental Laout. Most previous attempts to study deterioration have

 
 been inconclusive because of defective experimental layouts. A good layout

 
 calls for the simultaneous release of each of the four lots of propagated

 
 birds (as a,b,c,d) plus wild bandings as controls. There should be several

 
 hundred birds of each lot released for a series of successive years (perhaps

 
 three years). 
 
     To do this requires the accumulation of stocks confined in four tight

 
pens. Second-generation pures will be available in 1941 (Lot b) and third-

 
generation in 1942 (Lot c). The four lots can then be maintained continuously,

 
for the experimental period of three years, by the annual addition of birds

 
from wild-gathered eggs. 
 
     Preparations Needed. Mr. Bell and the Institute should first express
their 
 
approval or disapproval of this project, so that if approved, the necessary

 
stocks can accumulate, and the necessary alterations in pens made. 
 
     Hochbaum should then seek criticism of the experimental layout from

 
geneticists, from the U.S.B.S., from statisticians, and all other sources
of 
 
advice. 
 
     Project #?. Propagating Canvasback. This is a nearly-but-not-quite-

 
finished piece of work pioneered by Mr. Bell and Mr. Ward. It has heretofore

 
been proposed that we publish on the cultural methods used, but Hochbaum
now 
 
very properly raises the question: Should we publish before we have succeeded

 
in getting eggs and young in captivity? I think not, and I suggest we use
the 
 
interval of two years which must pass before we can embark on Project #1
to 
 
finish up the canvasback project. 
 
     No eggs are being obtained from captive deepwaters, despite seemingly

 
healthy stock. Eggs were obtained one year when the birds had access to 
 
natural water. Present exhibitions of mating behavior are confined to the
short 
 
  

					
				
				
-7- 
 
 
daily period when water is admitted to the tank. The clue is then that 
 
either natural water or some food contined in it is  yprarequisite to breeding.

 
     Completion of a technique for breeding canvasback is important for three

 
reasons: 
 
          1. As an addition to game farming techniques 
 
          2. As a part of the hoped-for ultimate monograph on the canvasback

 
          3. It is possible that the domestication study in mallard should

             ultimately be repeated in some deepwater species, as canvasback.

 
     It is therefore recommended that a breeding pen be constructed connecting

 
with the ditch leading from the bay to the pump house. This need not have

 
overhead wire, and will cost no large amount. A "sun porch" should
also be 
 
added to the west wing to give the ducklings natural sun during the period

 
ordinarily spent indoors. 
 
     There is a pretty good chance that this slight modification of the present

 
technique would yield eggs from captive canvasbacks. 
 
     Let it be clear that this proposal is an empirical cut~aad-try investigation

 
made to finish up a nearly finished piece of work. It may fail. 
 
     No really scientific control of all variables is proposed. To do this

 
would be very costly in time and funds, and wold call for a kind of manpower

 
we do not have. 
 
     It is possible, of course, that once we get a physiologist to Delta
that 
 
further modifications of this work may suggest themselves. 
 
 
                                (D) Publications 
 
     We have t500 for "Bulletin No. 1". Mr. Bell, the Institute,
and Dr. Pirnie 
 
have all expressed a preference for publishing our own bulletin, rather than

 
using journals and then assembling reprints as our output. 
 
     However, since these decisions were made, new conditions have come to
light. 
 
 It is increasingly clear that some of our findings need to be published
at once, 
 
  

					
				
				
- -. 
 
 
else somebody else will do so. The cloacal sexing and aging of live birds

 
is an example. 
 
     Other findings will not be mature as soon as we thought they would be.

 
Hochbaum's reluctance to publish the hatchery technique is a case in point.

 
     I am convinced that to wait until we have a large enough "batch"
of 
 
findings to make a bulletin does not fit our natural scheme of operations.

 
     Moreover the "Woods Hole" type of station (inviting other
institutions 
 
to come and do work) will never fit into the independent bulletin scheme

 
without irritating delays and troubles over authorship. 
 
     I therefore propose that unless our advisors or sponsors definitely

 
disapprove, that we proceed with journal publication of our output as it

 
becomes ready, using our publication fund to lay up reprints for later 
 
assembly as a bulletin. 
 
     When the time comes to assemble these as a bulletin, suitable covering

 
material, both textual and illustrative, can be added. 
 
     When the time comes that we have material for a bulletin, or for a book,

 
there is nothing to prevent our printing it on our own account. 
 
     Hochbaum must have a definite objective to aim at, else labor will be

 
wasted. The old objective no longer fits the facts. This is my excuse for

 
proposing this solution for the problem. 
 
 
                                  (E) Fiscal 
 
     My proposal that Delta funds be deposited in Canada is no longer tenable

 
for Fd Ward will shortly leave on military service. 
 
     I therefore propose that the fund be disbursed from the Institute office,

 
as at present, with this modification: a petty cash fund should be given
to 
 
Hochbaum so as to avoid long delays on small outlays. An initial patty cash

 
fund of $100 will do.

Dear Albertt 
 
          I ex really worried about your report. but heartily 
Vywpathatic with you. I th~ink Mi Kard can do us some good It 
he will spea out. I am afraid I can do nothing 'beas.s I 
w      there and con't cite details. Tou have my permietion, 
however, to urge ? to lay it on as strornlyas he can. 
 
          I an glad you had some rains despite the flooded 
Aests.- 
 
          I will b up about July 10 uness SelAtor Walcott 
say he can go in Augus~t but oan't go in July. I think It 
would be worth hile to got hin to Delta. 
 
          Mort Palmer has resigned and I am reeowoandig SIll

          Very possibly you. are right as to Inserting moes 
hatchry in the Sell letter. H         Senator Walott has 
alreaysen~t the letter. Should you want a suplmentary 
letter, plese fr, it. 
 
          I dnnst kw how to advise you abot Dcks Unlimited

 Dear Professor Leopold: 
 
        Last week Mtr. Cartwright asked if we would be able 
 to cooperate with one of his technicians in bending wnttrfowl. 
 Like up they have had difficultipm with sum'pr traoping and 
 would like to send one of their men h-r- to work on the 
 problem. In all our discussions we have been open minded 
 on this subject end,as I remembpr, were willtnF to cooppr-te 
 with their vrour on any problemd they xiphed to work out 
 with up here. I believe that there is more tbpa the desire 
 to solve a problem,howpver, for Mr. Main has asked COrtwright 
 to band 20,000 ducks tVip year. Their own Big Grass marsh 
 is nearly dry again this vear and this is the best field for 
 operation in kenitobN, They probably would want to keep 
 their own records and I am afraid,oyen with close understandings 
 between the two groups,this might be the beginning of serious 
 complications. I would be perfectly willing to have them 
 come in and work with us on our own banding as a problem to be 
 solved but I wonder if we should encourage them to extend 
 their own trapping operations to our study area. 
 
       We have gone over the rrocosed letter from Oenator "alcott 
to Mr. bell end wonder if the hatchery shoulO not be mentioned 
in the statement of obj-ctives. Much of the work we are doing 
c nters around this and would be impossible to carry on without 
it. I think it would not be amiss to inclule it,referring specific. 
ally to its importance in studies of waterfowl natural history. 
 
       I am enclosing the payroll for June. Ralph Morrill 
reported June 7 but rather than breaking up the $loo.oo for 
this month I am asking him to make uo this time before he 
leaves in September. 
 
 
                           Yours s!ncrelv, 
 
                           Albert 
 
cc :Pirnie 
 
P.S.    Morrill is a v~ry likable chap and fits in very well with 
the crowd. I am having him mpke u    a series of young ducks 
for your office and wond,-r if Iry could not check over the 
collection for anythinn else which you rpall- need . We made 
a case for the "elts collection and I think you will went one 
 
  

					
				
				
 
 
 
 
 
likP it when you see it. 
 
 
       Heavy rnins Tuesdey brought the mersh up but I am 
afraid a good npny n-Ft wiill be flooded. LvIl is checking 
up on thpm this morning. 
 
       Pirnie's small critictimp of ovrythinq and everyone 
in gpnoral have all of us in poor spririt for they do not 
come in the form of constructive ndvice. The boys begin 
their dey in the hntchery nt 1:70 or 5 AM and with his constant 
harangue it's hard to bear thtouphout thp day. I know that 
he doesn't mean it but I em finding it hard to kP~p a happy 
household that hee been running very smoothly. Ed had a heart-to- 
heart talk with him, lpst night and perhapp things -ill brighten up.

        Dear Aldo: 
 
             Thank you very much for your letter of March 22 in which 
        you are ordering a balance and weights with carrying case for 
        a graduate student who is at work on a project in Canada. 
        Shipment will be made just as soon as the case can be con- 
        structed. 
 
             I have had the question of shipment into Canada looked into,

        thinking' that there might be some difficulty from the standpoint

        of customs. Canadian educational institutions may import goods 
        duty free, but all others must pay duty. Presumably therefore 
        duty will have to be paid on the shipment when it goes into 
        Canada, but if the project is a temporary one the suggestion 
        may be in order that when the shipment is cleared in customs 
        a statement be made that the apparatus is for temporary use and 
        will be taken back to the States within a certain period. It 
        may be that under these circumstances either the duty will be 
        waived or a receipt may be given for duty paid, on which a 
        refund may be obtained when the apparatus is taken out of 
        Canada. 
 
             I still haven't given up hope of seeing you and members of 
        your good family look in on us in Evanston some time. I have an 
        archery "museumv which might afford you some interesting hours.

        With all good wishes, I remain 
 
                                        dlyyours,

        PEK:HP 
 
        P. S. The duty will amount to approximately 307o of the value 
        of the shipment.

Mr. Aldo Leopold 
Prof. of Wildlife Management 
University of Wisconsin 
Madison, Wisconsin. 
 
Dear Prof. Leopold: 
 
          Thank you for the notes on the connection with 
the University and I shall by all means plan my part in 
the program so that it will not draw too heavily on the 
work here. No commitments have been mare r arding this 
on my part. In vip, of our discussion last winter, howevem, 
I felt that I should ro as far se pospible .n workina with 
the Univprsity. We will of course, stress the point thntthis 
course, if it develops,is not to bp considered as advertized 
in any way as offers a training for professional students. 
 
          Dr. firnie has just arrived and brought with him 
your letter setting forth the discussion of your meeting with 
him. In a previous letter you had asked for suvvestionp reza- 
rding the person for the Canadian repfesentative. I can n~ne 
but two, Mr. Criddle at Treesbank and Prof. R.A.Wardle at the 
University. 
 
          Frof. Wardle is a parasitologist but is the only 
person at the Univrsity who would be qualified. In your second 
letter you have set this aside for a while and we can go over 
this later. 
 
          In regerds to the artificial propagation of canvasback, 
I think that we should adopt some sort of a policy on this 
question. I can find nothing in the earlier propecals or agreementA 
that imuld Awclude this. We discarded the idea rhen the project 
was started end hve pasred around it ever s"ce. If we do not 
wish to cnvpr this because it is not "scientific" or for any 
other reson lets say so now and make it clearin any pronosals 
or agreements that this is not within our interests. Personally, 
I owuld be inclined to follow with Mr. Bellts interests in this 
matter. This may be only to the oxtent of coorersting with other 
groups interested in the work, cornell or the Carnegie Institutions 
and pooling our efforts rnd facilities. I owuld not want to tefe 
this alonp nor tould I want to put it entirely on Peter'- Ohoulders, 
Both the Carnegie Institution and th Cornell pre interested in 
this as a problem in endrochronology And I believe it is in such 
a problem that interests Mr. Bell. I believe that proped pen

conditions here would bring about breading in canvasback 
and any study would entril some pbysic9l improvements. 
Regardlees of this, however, we must do e good deal of 
re-building of endosures during the npxt two yoers. 
 
 
                               Sincerely yours,

     It might be well at this time to set down the psps which we have hal

 
in mind at Delta. 'e hope to *at the steae for & Aw approah to brooedi4

 
gund studies. We believe that onoe this new m  roah is demonstrated, it 
will be -used an developed by other aencies. Ne hope to end up with an 
 
uthoitative aonograph on the eoology and. aneiusnt of the local brooing 
 
specs, or at least of the dvn duck. Inci4detally, the Delta wok will 
 
train a limited maber of yz   mes as experts in this fiol&. 
 
     In orde. to make sure that the Delta veature ties in with the Cwze4ianst

I recently a*ed Rto   Lloyd to s.*e with Dr. Piwnie ad Prof. Leopold as

       Dear Dr. Leopold: 
 
 
       Thank you for your letter of the 25th. I think 
       the objectives mentioned should be specifically 
       stated. I do not think, however, we should 
       limit the ecology and management to the canvas- 
       backs but to all deep-diving ducks. 
 
       When I say I think they should be specifically 
       stated, I do not mean in the form of an agree- 
       ment. I do not think we want an agreement, 
       but merely an understanding of the objectives 
       which we have in mind and under which the work 
       is to proceed. Any kind of memorandum to me 
       of this character will be entirely satisfactory. 
 
       After all, it is a matter of good faith between 
       the contracting parties. 
 
 
Yours very truly,

    Dear Dr. Leopold: 
 
 
    I wrote you yesterday, but after looking over the 
    correspondence, I am inclined to have the matter 
    covered in the following way: 
 
    I will write a letter, such as the attached, to 
    the American Wild Life Institute, and they will 
    in turn write me a letter stating what they 
    propose to do with the funds. 
    If you approve of this and the letter itself, 
    will you have it forwarded, and will you write 
    Mr. Palmer suggesting the type of letter he 
    should write back to me that will cover the 
    subject. I think it should be informal, for, 
    after all, as I said in the other letter, it is 
    a matter of good faith and I am willing to rest 
    in theirs, if they are willing to accept mine.

                        Dear Aldo: 
 
                                        I am attaching herewith copy of a

                        letter just received from Hoyes Lloyd which is pretty

                        rmach self-explanatory. 
 
                                        This restriction will obviously also

                        apply to Dewey Soper. Who, then, is the next best

                        bet north of the border to place on this job? 
 
                                         I'd like to see old Ted White become

                        more active in this work again but I don't know 
                        whether he is in a position to do so or whether he

                        could fit into this job at all. This is just a passing

                        thought. 
 
                                        I have sent Senator Walcott a copy
of 
                        your letter on the Technical Committee without any

                        recommendations or discussion. I think this merits

                        considerable study and discussion with Gabe as well

Professor of Wildlife Management 
Univerpity of Wisconsin 
Madison, Wisconsin 
 
 
Dear Professor Leopold: 
 
       Yesterday Mr. Cartwright and I met Professor R. A. Wardle. 
head of the Dept. of Zoology at the University, for the purpose 
of discussing the possibilities of bringing about a closer relation- 
ship between the University and our two groups. Professor Wardle 
is keen on the idea of bringing wildlife management into his 
department but, as you know, is handicapped by the lack of funds 
to carry even a small program.   It is his feeling,'however,that 
a start should be made now with all that is available at the 
present time and eventually this will develop into something that 
can carry itself. He is hoping for some sort of a cooperative 
sponsership of a wildlife management departrpent but feels that 
this cannot come about until a start is made from scratch. The 
work should start as soon as possible and he believes the best way 
of making a beginning is to present a course in wildlife management. 
 
       He must look to the outside for help in this and the 
manpower and material in making this beginning must come from 
our groups. To this end Ducks Unlimited is equipped to offer the 
services of Mr. Cartwright as well as what equipment they have 
on hand that would be of material aid in beginning this work. They 
could not promise funds,but in a close pinch would probably be able 
to be of assistance. 
 
       For our part I have said that my time would be free for the 
 University during the second term and that the facilities of the 
 Delta Station were at the service of the University for their 
 use as a field and research station. 
 
        Professor Wardle then proposed that Mr. Oartwright and I present

 a course during the spring term of 1941,the program to be sponsered 
 by the American Wildlife Institute. Mr. Cartwright and I are to draw 
 up a tentative plan outlining the work and objectives. This will 
 be sent to you for your review,additions and revisions and then 
 will be presented by you to the University. Dr. Wardle has said 
 that Mr. Smith, the President of the University is very much 
 interested in this matter and that he anticipates no difficulties 
 in having this course placed in the University curriculum during 
 the spring term of 1941. 
                       and L 
        Mr. Cartwright/are now working up our ideas and will meet at

                         Winnipeg. 
 
             My dear Cartwright: 
 
                            I am greatly interested in your letter concerning

             Mr. Hochbaumls suggestion as I have felt for a long time that

             this Department should in some way try to co-operate with you.

 
                            W~e have unfortunately no course here that would

             tend to stimulate the interest of students in Wild Life Manage-

             ment or train them for research work or field work in that subject.

 
                            Frankly I would like to see such a course put
on 
             regularly here as part of the zoological curriculum, but given,

             if possible, by a representative of Ducks Unlimited, preferably

             you. If the American Wildlife Institute would make a grant 
             sufficient to cover the fee of the lecturer there would be little

             difficulty in fitting such a course into the curriculum. The

             number of students attending it would be small, as I would 
             restrict it to a selected group of senior students, but they
would 
             be keen. 
 
                             I shall be delighted to meet Mr. Hochbaum and

             yourself at any time or place convenient for you. 
 
                                               Sincerely yours,

Mr. Aldo Leopold

UnTvrtty of Witconsin

Dear Professor 6eopold: 
 
       Thank you for the nell correspondence. The only comnents I have 
are as follows: 
 
       1) The objectives,as far as the studies go, should be stated 
more clearly in the agreement so that Mr. Bell can understand and 
discuss them and realize the importance of the ends we wish to reach. 
This should also include a place for continued studies of the 
problems involved in bringing about the breeding of canvasback and 
other deepwaters in captivity and is, I believe ,what Mr. Bell is 
driving at when he refers to "fundamental research" At the time
I 
received this correspondence Mr. Bell had sent me several notes concern-

ing the use of a cottage on the property and In these he mentioned his 
interest in continuing breeding experiments at Delta and pointed out 
some of the work being done along this line at the Genetics Laboratory 
of the Carnegie Institution from which he had just returned, I know that

he is very much interested in continuing work along tbh@i line in which 
a beginning was made in 1974 with Dr. Roweb. 
 
       2) We should keep Mr. Bell more closely in touch with what we 
are doing. I realize that this ip more or less at my end of things,or 
at least reporting more carefully to the Board and to this end I shall 
submit progress reports at definite periods throughout the field 
season. 
 
        I am glad that we are now free to ask Hoyes LLoyd to serve on the

Board and I have no suggestions to make in repgads to the prooosed letter

that has been drawn up. I do wish,though,that ueltp 1,ps the place 
for a leisurely visit of the Board mrmbers rather than the place 
for the formal Board meeting. We wpnt you to have 6* much time with 
the project as possible and we want to get as much time with you on the 
job as pe cohlo. 
 
       I am enclosing the payroll and hatchery expenses for the Month of

May. Lyle begins work for the Institute funds June let and asked that 
he not be included for May. 
 
      Had an inch of rain which has brought the marsh up a bit. It uwas 
 so shallow that P canoe could not be floated in some of the bnys.

P.S.       (Thank you for taking care of the exoense account. This

want to send it through until the matter of money was settled. As for 
the scales I had thought that they mpre to be osid out of offic-P funds

    Dear Professor Leopold: 
 
 
    Many thanks for your letter of the 8th. I don't 
    think it is necessary to call in any attorneys in 
    respect to this matter. I think it could be 
    covered by an exchange of letters, wherein I say 
    to the Wild Life Foundation that I am anxious for 
    a continuance of the work carried on at Delta, 
    that with their co-operation I am willing to make 
    an annual donation of so-much per year for so-many 
    years, provided the work can be adequately carried 
    on along certain lines. Then I could get a letter 
    from them saying that they too were interested in 
    the work, and they hoped to have additional funds 
    available for that purpose, and then expressing 
    what they hoped to do. 
 
    My offer would be contingent upon the work's being 
    carried out, and theirs would be contingent upon 
    whether they got the money from me -- so there you 
    are. What do you think of the idea? 
 
    Best regards. 
 
                             Yours very truly,

Dear Prof. Leopold: 
 
          I am submitting an expense account for March and 
April so that this will be in order when the budget comes 
through. 
 
          Everything is moving along very nicely. Have been 
collecting eggs all week, mallard and pint~il, and have nearly 
completed our settings for these species. Ed has brought the 
guides over for thid week which helped a great d-el for the 
back marsh is dry and river duck nests are few and far between. 
Canvasback and redheads are just beginning to nest and we 
will wait a week before the next collection. This has kept 
me at Delta and r-*ur meeting with the University group is 
later in the month and there is no news on this point. 
 
          Lyle has been busy with the ground squirrel study 
and has already uncovered a slew of material. We are all busy 
with the hatchery but by deviding the work are finding plenty 
of time for other things. By the way, when the budget comes 
through, Peter's pay should begin withlt. 
 
          We are in the midst of the worst dust storm I have 
seen yet and a good dpel of the prairie and some of the marsh 
are in the air. The marsh is very dry and over a foot lower 
than last year. In generwl, there are more ducks this year 
with a very remarkable increase in cans. 
 
 
                            Yours Sincerely,

       I received the signed copies of the cooperative

       a letter, copy of which is attached. SinceE." 
       I have had a wire from Pirnie saying that he 
       felt the changes I suggested could be worked 
       out, I have on this date forwarded to the Ameri- 
       can Wild Life Institute a check in the sum in- 
       dicated for my participation. This is a direct 
       contribution to the American Wild Life Institute. 
 
       The more I have thought over the matter since I 
       wrote Pirnie, the more I dislike the cooperative 
       agreement. I think there should be a pledge on 
       my part to the American Wild Life Institute to 
       support its work, for such a time. In return, 
       I should have a memo from them that they propose 
       to and will conduct certain work which would bei  ; 
       outlined in the agreement. Similar memoes would 
       be had with you and Pirnie. 
 
       Naturally I am making these contributions to 
       scientific work and   want to receive such bene- 
       fits of tax deductions as the law permits. I have 
       sent the check because I do not want the work 
       delayed and I have no doubt we can work something 
       out which is satisfactory.

Copy of letter 
 
 
                                         April 30, 1940 
 
 Dr. M. D. Pirnie

 Battle Qreek, Michigan 
 
 Dear Dr. Pirnie: 
 
 I have at last before me the Cooperative Agreement 
 respecting the Delta Watetfowl Research Unit. 
 In principle I am entirely agreeable to the proposals 
 here set forth, but there are one or two things about 
 the agreement on which I would like to receive either 
 a change, or an interpretation: 
 1) Dods the character of the agreement void the 
     contribution, from a tax standpoint, as being 
     a contribution for purely scientific puzooses? 
     I know I could give it to the American Wild Life 
     Institute, and the Institute could in turn make 
     tae contribution, but iam not at all sure that 
     i coild get the tax allowance as it is set up. 
2) The purpose of the Delta Station as set forth 
    should, in ny opinion, be more inclusive. The 
    implication is largely that of conservation and 
    management work, with no indication that it permits 
    fundamental researoh. o reference is made in that 
    portion of the agreement in respect to hatchery work 
    or to migration. I have no doubt it was the inten- 
    tion to include these and not to limit the scope of 
    the work. 
3) The budget does not contain any elements for 
    incidentals, which are bound to crop up, and 
    gives very little room in which to turn around. 
I hate to hold up this matter any further, because it 
has already been too long delayed. I am answering your 
letter very promptly because I hope these things can be 
cleared up, so as to avoid as much further delay as 
possible. 
If you also think these matters can be cleared up, 
I would suggest that I immediately make the contribution 
to the American Wild Life Institute. That will iron 
out the matter of the tax situation definitely, and 
I have no doubt we can arrange about the definitions 
later. I further suggest that, If it meets with your 
approval, you either wire me  r i         s     t we 
can proceed at once. 
                         Xours very truly,

Dear Aldot 
 
            I have talked to Ted Doremus about 
the method of handling the funds for the Delta 
project and he is very much in favor of 
utilizing a Canadian deposit to be checked out 
by a reliable man in charge. 
 
             I wish you could give us the name 
of the mam who will do this and something about 
him that I can show my people to satisfy them 
on this score. 
 
             I was very much concerned about the 
conditions mentioned in your handwritten note. 
I sincerely hope they have improved. Here, we 
have had an abundance of rainfall and could well 
spare a large percentage for Delta. 
 
             Beat regards.

Dear Prof. Leopold: 
 
          It is good to hear that the budget is going through 
and thank you for your troubles in getting the agreement settled. 
 
          Everything is going nicely, although there are too 
many things happening at once now that it is May. We started the 
incubator for Art~s wood-duck eggs and tbrv ar5 coming along 
nicely. Unfortunately Art will not be able to raise Delta ducks 
this year. 
 
          The marsh is ooen and most of the duck- Qr- back. 
Mallards and pintail are nesting and we will begin egg' collecting 
May 6th. 
 
          I have a meeting with the Zoology Dept. of the University 
of Manitoba and it looks ar though we may find a rsy for cooperaticn 
with them. 
 
          The scples havenarrived and I am awaiting approval from 
Ottawa to bring them in. 
 
 
                           Sincerely,

Dear Aldo: 
 
               I was thoroughly disappointed at 
missing the Conference this year. From all reports 
I understand it to be the most useful of any of our 
Conferences so far. 
 
               I have just signed the revised agree- 
ments for the Delta IWaterfowl Station project and 
these are being passed on to you for formal action 
by the other cooperators. 
 
               I am very anxious to see the field 
activities at Delta and muld like very much to get 
up there some time between now and September. What 
would you suggest will be the best time to look over 
these operations? 
 
               With very best regards, I am 
 
                                  Sincerely yours,

 Doer Prof. Leopold; 
 
           I am afraid, now that I am back, that it would 
 be almost next to impossible to get down this June in time 
 to take an examination. Fassett tells me he is leaving Parly, 
 we will have a student to break in and Pettingill porsibly 
 Sutton will be here early in June. Thank you for suggesting 
 the recommendation for the non-resident rcholarship. If they 
 are limited, I would rather let some one else have a try at 
 it, for I can carry myself alright. Otherwise, however, I 
 would aopreciate the chance. 
 
           In rpgprds to the budget, will you let me know 
-when it is alriwht to offer the assistantship to Morrill, and 
also when we will be Pure of money for the local,aasaistante 
for egg collecting. 
 
           The ducks have been Douring in thesp last few days, 
 mostly mallards Pnd pintails, and the geese are legion. We 
 will be collecting eggs in less than two weeks. 
 
 
                              Sincerely,

Dear Aldo: 
 
      In reply to your letter of April 11 I may say that the two 
titles "Do Drakes Outnumber Susies?" and "The Sex Ratio of
Banded 
Ducks" refer to the same paper which was published only once, namely,

in American Game, Vol. 21, January-February, 1932, PP. 3-4, and 16-17. 
I gave this paper before the A.O.U. at the Detroit meeting on 
October 20, 1931, and it is listed on the program which was published 
in the Auk, Vol. 49, page 58, January 1932. 
 
     Its appearance in American Game is, however, its only publication. 
 
     It is my belief that the extensive interest in this subject that 
has been manifest in recent years may be traced directly to this 
paper. Incidentally, when I submitted it to American Game it carried 
the title "The Sex Ratio of Banded Ducks" and I believe you may
iuagine 
my amazement when I first saw it in print under the title of "Do 
Drakes Outnumber Susies?" Seth Gordon was then president of the 
association and I believe responsible for a good part of the editorial 
work on American Game. 
 
     With best regards, I am 
 
                                 Sincerely yours,

Dear Alberti 
 
     Plase consider this iV offieial approval of your 
appointment of Lyle Sa-ls and Ralph V-rrill to the 
positions as research assistants for the three mionths 
durIng the euswr of 1940. I think it very fortunate 
that Lyle can start work early enouZh to help during 
the first big rush. 
 
     Thanks for the outline* I shall at least try to 
arrange to make available to you the best of what I         a 
have on the deve lomnt of early pl     -gesa, ohi     lV.C   - 
acquisition and loss of juwnal tail feathers.    I 
doubt tht Bulletin I is the place to go Into pluae 
details. Don't you think this had better be done by 
species In later publications? 
 
     A physiology and biology teacher with a Masters 
Degree from the University of 1iichigen wishes to oom 
to Michigan State College for work toward a PhD. U 
leans towd a problem in anatom     under Dr rennel, 
Would he be overwlapping or getting in yu way if he 
undertook a problem on seasonal and a-e ohan-es in the 
loaea -the bura and reproductive organs found there? 
He could have eons iderable lYallard and pheas~t material 
from the State 0" Farm and of course we could arrange 
to have certain other species for his study material, 
Am I wrong in assumng that you are primarily Interested 
in you field study and paintiag! or do you plan to do 
more intensive work on the bursa, etc., of the sort this 
student might tackle? ';'hat I wish to know is your re- 
   actions to his taking up such a problem, whether you 
idght have mterial for him or will you be wanting all 
the Delta material for your own researehes and publi. 
*ationse Shall appreciate a prorpt reply as it is high 
tim that this candidate decided on his probleuo

Dear Prof. Leopold; 
 
          In spite of the mild winter here spring is more than 
a week late this year and tbo first geese did not arrive until 
today. 
 
          With the first of April Qonu it is high time we began 
to plan for the summer assistants. I assume that the budget approved 
in Washington is the same as outlined in your "Cooperative Agreement".

This provides 4700 for two assistants,$100 eae-h for a period of 
three months and travelling expenses. For one of these assistantships 
we are counting on Lyle. Arriving early this year, he will be a 
great help for 17e are going to be a bit crowded carrying the hatchery 
by ourselves. 
 
          Miles has recommended Ralph Morrill for work this summer. 
He is a protege of Van Tyne whose recommendation I am passing along. 
In view of the fact that there is enough to carry Lyle- 4as as 
assistant and because Morrill is Miles"' choice for Delta work I am

inclined to favor his aopointmen*. It may not be entirely within 
our policy to take on a museim man but we will be loaded down this 
year if we do not have someone to take over a good share of this 
work. We might look for someone in our own group to do this work, 
but we have more or less committed ourselves to take someone of 
Miles' choice and I am sure that Van Tyne would not recommend anyone 
but an able person. 
 
          I have not heard from Ottawa about the rn~les but if 
they are ready to ship they might as well be sent on for I am sure 
we can get them in somehow. 
 
 
                                     Sincerely Youre, 
 
  

					
				
				
 
 
 
 
Wmyandug conge.rin Delts Sud~n- ssittu~       for 1940 
 
 
       With the Delta budet approved for the 1940 season we are 
free to go ahead witb appointments for student assistants for the 
-    r Season. The budget as set forth in the ' Cooperative Agreement 
allots $700.00 for two assist&mts-lOo. each for a priod of three 
sonthe with $50. .aob for travelling expenses. 
       Of the candidates reoooended for the posit ions the two 
which appear to m0 to b. best fitted for work at-Ihla are  alph 
Vorrill, and Lyle %#wles. 
       Ralph Morrillreommuded by Dr. Pirale, is a protege of Dr. 
Van yne. He hau worked for several year. with Van Tyne who recoad* 
his highly for work at Delta. He is--a student at itohigan State 
Norml College and has bees an assistant is the Bird Division Laboriat- 
ory of the Untv-roity of Niehigas. I an Inolined to favor the app- 
ointment of Morrill for one of the assistantships because of his 
abilities as a prepsrator. He bar been trained in this work by Van 
Tyne and in the course of the past few years has made up over two 
thousand skies. The operation of the hatchery is entirely upon our 
heads this year and if we are to take advantage of *ll of the hatchery 
speotaiarat!rial there will be time for little else. A person with 
orrill's qualification will leave us with more time for the field. 
I understand that his abilities are not ecafued to museum chores 
and that we my rely on hi; to help with the hathoery work and 
experiment, with the oaptive birds. 
       I have not met Mrrill, but Dr. Pirnie knows his personally 
and Van Tyne vouohes for his ability to get along with people under 
adverse coeditiones. The time at wbhih he could report for work at 
Delta, however, would have some bearitn upon bis arnointment. The 
most crowded period of the yeor is betswe. the last week in iay 
and the middle of June. The sumr assistant should be available 
by the first week of June at the latest. 
       Lyle Sowls is returnung to Delta before the end of April, 
and plfns to remain unil early fall working princinally upon his 
study of the -ranklin Ground 9qStrre. Lyleis familiar with the 
batchery routine and as, without the breeds for egg collecting 
this yeart we will need an assistent during the early season, all 
of us at Delta would like to have Lyle back. Lyle ii planning to 
carry himelf pert way on his ow   funds but w-uld not be able to 
oarry himself through the season entirely on his own. 
       Peter and    'Ward are favorably impressed with Morrill and 
Lyle as Candidates. I as satisfied that they will fit into our 
program and an passing their nes o for s

Dear Leopold.- 
 
 
               It is entirely satisfactory to have 
the Delta findings printed in the form of separate 
bulletins, and I appreciate your advice that this 
is the plan that is now in prospect. 
 
               When the suggestion comes along of- 
ficially about my acting as a trustee for the Delta 
investigation it will receive immediate attention. 
 
                With kind regards.

Dear Prof. Leopold; 
 
          This will let you know that wd reached Dplta 
alright. Stopoed over to sep Dr. Roberts and Mr. Kilgore 
on the way up as well as Pettingill. Sewall is coming up to 
take colored movies of the hatchery and marsh in June. 
 
          It is good to know that you werA able to cover 
thr Delta Program so well at the conference and that the 
budget is settled. I believe that I can get the bulletin 
material out as scheduled. I am afraid that you must have 
nut yourself out quite a bit on the pictures and I went to 
thank you for showing them. If you would like to have the 
pictures handy in the office why not keep them with you at 
Madison. 
          There was lots of snow throuwh Minnesota but the 
Portage fields are black and dust is blowing. Water will be 
lower in the marsh this year than last end we will not be 
able to keep the old ducks in the marsh Den. Consequently 
we are building a new pen and water tank at ihe edge of the 
flying pen for the old ducks. 
 
          Ev-rything is fine h-re and everyone is set for 
the coming season. Ed has a caboose moved in for Lyle and we 
are fixing up one of the little cottages on the ridge near 
the duck house whi(h will be much handier for the hatchery 
work this year. 
 
          Crows are moving in and it will be but a few 
days before the ducks and geese will be with us sqein. 
 
 
                                Sincerely yours,

Dear Aldo: 
 
              I am attaching hereto the copies of 
the agreement and budget approved by our Executive 
Committee and signed by Senator Walcott. 
 
              I have left the budget as you presented 
it, including the $500.00 item which Mr. Carpenter 
agreed to subscribe at our meeting. 
 
              You can appreciate I am sure with what 
satisfaction I write this letter. 
 
              As to the period this program is to cover 
I would suggest that the three-year schedule begin 
January 1st, 1940 and include the three calendar years, 
1940, 1941, and 1942. If you have any other ideas on 
this please let me know.

Dear Aldo: 
 
             I have your letter of the 29th and shall write 
Bell immediately. I've been afraid all along that he 
would lose interest in the proposition, feeling that the 
Institute was letting him down. So, I have been keeping 
in touch with him as much as possible without breaking 
down my own morale from too much alibiing. 
 
             Now with respect to the bulletin, I'll talk 
with Senator Wal cott about this vkhen he gets here. He 
has promised to come down this week and go over some 
things in advance of the Conference. I appreciate very 
much the importance of Canadian "good will" but certainly 
thirnk..  should publish its own separate report on the 
work of the Delta project. 
 
             This research work is of no valutwhatso ever 
unless it is properly utilized and that meansapublish the 
results for the use of everyone. That $500.00 item must 
be included in the Delta budget and I think there will be 
no difficulty in having it set up there if you urge# the 
point at our Board meeting. 
 
              Best regards. 
 
 
Sincerely yours,

                                      I am glad you got your file of AMERICAN

                        GAME and AMERICAN WILDLIFE and if anyone can put
it 
                        to good use you will. 
 
                                      I am interested in the new proposal
for 
                         the bulletin on the Delta project and will be eager

                         to get the details.  I doubt that we will have much

                         difficulty in having this approved at a later meeting

                         of the Executive Committee. 
 
                                      I have not written Mr. Bell as yet
concern- 
                         ing the action of the Executive Committee on the

                         Delta project because I need but one more reply
from 
                         this Committee to make up a complete quorum. When
I 
                         receive that, which ought to be within a couple
days, 
                         I will write him stating that the budget has been
fully 
                         approved. I hope he has not changed his mind by
that 
                         time. 
 
                                      With best regards, I am

Dear Morti 
 
          I think it would be a good idea for you to write Mr. 
Be.1, stating how the projeot stands, even thoug your letter 
annot be the V ia praaorx1. I au afraid he has gotten the 
impression that the Institute ts nleatiin his offer. Jo, he 
won't th ,iaeg his wind, but I wt1d 1lc for him to kee his high 
opinion of the Institute. 
 
          The now proposal ior the balletin is not yet offtiial 
becaue Piles Pirne has doubts about it, but I will tell you 
persoaally wha it is. It Is propeoed to publish the Delta findins 
in the C                       and goet a sufficient stoc of re- 
prints to assemble t  per   icaly, bund in a cover, as 'ioessivs 
blletins of the Delta station. These asemblod bulletin  would then 
be sold at oost and the revolving fund used to bV future reprints. 
The gnod will aspects of p*bltshlng in Oanada ar. obvions. I Am our* 
the eche" would be cheaper ta printin our own buletin. 
 
          Ftrnies doubt is base& on the ampposition thAt the 
Institute and Mr. Bel1 would rather have a separate prInteA publica- 
tion wholly its own. If thq really prefer this, I am agreeablebut 
I doubt ver  uh ihithor Mr. 2.11 really prefers it. I think he 
would rather have the Canadian god will. 
          I am tellig you about this so that you oan think it ver 
and at the Gonference determine the proe ereme of the lavtitabe. 
 
          With best rse    ,

                   Dear Aldo: 
 
                                 I have your letters of the 19th, 26th, and
30th 
                   of January. The reason I haven't answered sooner is because

                   this Conference is beginning to beer dowm on me. 
 
                                 I am sorry that Al Hochbaum von't be at
the 
                   Conference. I was very anxious for him to meet our people

                   and tell them something of the work he is doing. He has
a 
                   happy faculty of instilling a feeling of confidence in
what 
                   he is doing. 
 
                                 The reason I wrote you as I did about the
status 
                   of the Delta project was simply this: "While Senator
Walcott 
                   signed the agreement, it was done subject to the approval
of 
                   our Executive Committee and I am atteapting to get that
by 
                   mail. As soon as I get the approval of the majority of
the 
                   Committee I will let you know. I feel confident that there

                   will be no hesitancy on the part of anyone. 
 
                                 I think you can proceed with your plans
as you 
                   stated you were doing in your letter of the 30th. The
only 
                   thing that was disapproved tentatively was the $500.00
for 
                   Bulletin No. 1. However, I feel that we will be able to
have 
                   this approved upon further consideration of the budget.

 
                                 As Chairman of the Technical Committee of
the 
                   Institute I think you deserve a complete file of AMERICAN

                   GAME and AMERICAN WILDLIFE and under separate cover today
we 
                   are sending you a set of the copies we have. 
 
                                 With best regards and looking forward to
seeing 
                   you at the Conference, I am

          Albet a&M   have been tali-g about the pposed bulletin

liabilities In both monae aM time that we wuld take am in printing 
ad distributing such a pblication. 
 
          Albert has now me a  uneetsion which I think mets, the

          I don't want to burden you with a Imngth reply to this

think well of Ito we should thea see what Mfr. 3411 and Mort Palmer

                         Dear Aldo: 
 
                                       Under separate cover I am sending
to you 
                         copies of the November reports of the research projects

                         and returning the October copies. I am doing this

                         simply because of the fact that I have made arrange-

                         ments to have extra copies of these reports made

                         for you. These you may retain in your files if you

                         so desire. They need not be returned to this office

                         as we have copies. 
 
                                        I agree with you absolutely with
respect 
                         to the burdensome nature of monthly reports and
I 
                         believe the folks over at the Survey now feel the

                         same way about it. Future reports are to be made

                         on a quarterly basis. I think this will be much

                         more satisfactory all the way around. 
 
                                        I think the Delta project is all
taken 
                         care of but I will hold off for a few days before

                         saying definitely that it has all been approved
by 
                         our Executive Committee.

       .ky belief in an unexpended balance has erisdn because I have 
not had the entire picture of Delta expenses before me. I was unaware 
that the $160.00 carry-over from last year was charged to this year's 
budget or I would have accounted for it at the beginning of the year. 
Perhaps the increase in salary was also taken from the existing budget; 
I assumed that it represented an addition to the budget. 
 
       I have knowingly overdrawn on the hatchery supplies and 
travel expenses but believed these would be fully covered by 
Peter Wardls unpaid salary for the last three months of the year. 
My monthly expenses at Delta as bpl1anced with the budget for the 
year would still show an unexpended balance,but not, of course 
with the additional e penses which did not sbow on my booke. 
 
       I feel very badly tbet this mistake has occurred 
 
                         Yours sincerely,

                     Dear Aldo: 
 
                                     Thanks for your letter of November 28,
relative 
                     to the $300 balance alluded to in your letter of November
19 
                     and in correspondence of mind of later date. 
 
                                     I have just received the final contribution
from 
                     Mr. Bell which totals $2,461.20 and includes the $111.20
for 
                     electrical equipment. Combining this with the $2,500.00
con- 
                     tributed by the Institute makes a grand total for expenditure

                     at Delta for the current fiscal year of $4,961.20 (U.
S. money). 
 
                                     In my previous correspondence, I pointed
out the 
                     total expenditures of Delta to date and the expenditures
to be 
                     anticipated for the months of November and December.
You under- 
                I stand, of course, thatI have no objections to Albert's
purchasing 
                     new equipment at Delta, provided there are sufficient
funds to 
                     cover everything. I just -want to make sure that there
will be 
                     no overdrawing on the Delta budget during the current
year. 
                                      S.LI.... ..taa.t..            . ..
...* . . .... 
 
 
                Apparently, Mr. BelA wishes to inIlude nis pur- 
chase of the electrical equipment as a part of his contribution 
and although this is not in accordance with my original under- 
standing of the situation, we must necessarily comply with his 
wishes. That item must therefore be included in the budget for 
1941. In addition, you will note that Mr. Bell's contribution 
has been reduced by approximately $40.00. My recent request 
to Mr. Bell asked for $1,250.00 which would have brought his 
contribution to $2,500.00, exclusive of the electrical equip- 
ment. Mr. Bell sent us $1,100.00. Unfortunately the Institute 
is not in a position to exceed the $2,500.00 previously agreed to. 
                                         Very sincerely yours,

Dear Aldo: 
 
 
                Thank you very much for the copy of your letter 
to Mr.' Hochbaum, dated November 19. I would like to comment on 
the last paragraph of that letter which would lead me to believe 
that Hochbaum had advised you that he had a $300 unexpended 
balance. 
 
                According to the records at this office, after the 
salaries for November have been taken out, there is a balance of 
approximately $298.00o Salaries for December and expenses for 
both November and December must, of course, come from this item. 
In addition to that, this balance includes $160.00 item carried 
over from last year. Therefore, the expenditure of ý298.C)0 
between now and December 31 would amount to $160.00 overrun on 
Mr. Hochbaum's budget for the current year. 
 
                In view of the situation regarding finances for 
the 1942 period, I think it is advisable to keep all expenditures 
to a minimum for it is entirely possible that the Institute will 
not be able to contribute as much in 1942 as we did in 1941 for 
the carrying on of the work at Delta. 
 
                At the present time, it looks like there will be 
a one-third reduction in the amount of our contribution to the 
cooperative units. This, of course, is not final and is given 
to you confidentially as Chairman of the Technical Committee. 
Until a final decision has been reached, this information should 
be kept in strictest confidence. 
 
 
                                         Very sincerely yours,

               P.S. Dear Albert: 
 
                      I have been wanting to ask you for your own appraisal

                      of your military status, and your ideas on how to jump

                      in the event you should be called. 
 
                      I can't think of any of the good men we have had at

                      Delta who might be available to keep things going 
                      except Bill Elder. All the other good ones are sure

                      to be non-available. In Bill's case, Illinois would

                      of course have a prior claim, but they themselves 
                      might be shrinking and perhaps able to spare him, 
                      especially in the summer. Have you anv ideas? 
 
 
Yours,

Dear Albert: 
 
I am muach impressed with the fundamental soundness of your advioe 
on the personal mtter I wrote you about. I think you he hit the 
mail squarely and given me some valuable guidanoe. 
 
I am glad the Des Moies trip me not unwelcome. I hesitated a little 
lest you regard it an an interruption. It will be, of oourse, but I 
think that trips to Des Moines and Toronto will be worthwhile. I 
like the subjects that you offer            , and I cannot improve on then.

 
I an writing Paul Miller to clear up the nature of the $300 balance, 
 
It pleases me that Paul Miller wants you to chair the marsh management. 
My only worry is that )his might operate to out off your own presentation.

The only idea on program which I have read is this: the Conference has 
nemver had the full benefit of the Illinois work. I think krthur should 
be invited to give his g   e pkp4 of the Horsehoe Lake in full and 
without regard to whose      are stepped on. It seems to me that the 
Institute might well askthe arzm  for his release during this brief 
period of three diys because of the national importance of his oontribu-

tion. Paul Miller could get Senator Walcott to present the request. 
 
In addition, I think Bill Elder, or somebody else able to speak, should 
summarise the Illinois work. I can tip you off confidentially that 
Trison is unable to suinrise it. I don't know about Bellrose's speaking 
ability. Bill could mke it clear and oconvincing. 
 
It will be a treat to see you at Des Moines. If you can spare the time, 
come on bakk here with me and stay with us while you are in town. If 
you can bring Joan, so much the better. 
 
                               With best regards,

Dear A.L.: 
 
 
       Thank you for your notes on the manuscript and for the 
very helpful comments on the fi~rres Pnd tables. I am worried about 
your eyes; please take it easy. I think I can work out the rough 
spots but I do want your appraisal of the technical points. Can8t 
you get at these by having one of the students read a bit each day 
as we used to review the journals together. 
 
       I know you will understand about the manuscrzpt and Mr. Bell. 
Ed told him about it and he. of course wanted to see it. When he 
left he tucked it away in his grip end I have just received the 
enclosed letter.   His chief criticism was acertain  repetitions 
carried over from one chapter to another. I am sure he will give 
an honest and careful review. He likes the color; I am sure that 
he does not wkhsh an# changes in form or arrangement. 
 
       I have only two copiesyours end Mr. Bell's . Thus I couldn't 
very well send one to Dr. Rowan or to Pirnie. I would rather wait 
until we iron it out before typing up additional copies. Perhaps 
we can count on Mr. Bell to iron out the spots that have evaded me. 
       " eturning to Mr. Bell and the manuscript, I have been a 
little upset in steoping out of routine tmmeaimhtm in giving him 
this before we had a chance to work it out ourselves and I understand 
how you might be somewhat concerned. His crtticisms were the same 
as yours,however,repetition and clarification; when he was here 
he spent some time going over these with me in the first chapters 
and I believe his comments will be clear. 
 
        I like"What is the Delta Duck Station". My only suggestion

concerns the original idea for the station. The question of 
American shooters here will always be a sore point, hatchery or 
no hatchery at. I think we should try to steer around this 
if possible. I havn't any better ideas right now by way of an 
alternative tut will try to have something by next mail. 
 
        I like your suggestions for the tables and figures very 
 much and they clear up a good many points for me. I'm still 
 mostly thumbs when it comes to these. 
 
       With the unexpected guests at the Lodge,we 4ave all been 
 a little pressed these last two weeks but I will try to get the 
 sex and age chapter off as soon as possible 8, well as k'eteI coot 
 
  

					
				
				
 
 
 
 
paper. 
       fiater is still on the wheat fields and much of the wheat 
has not yet thrashed-never will be now for it is sprouting. This 
should mean that we are on the upgrade for water for the coming 
spring at least. 
 
       Water on the wheat fields has meant the smallest mallard 
kill in years. Many of the mallards are apoarently using the 
wheatfield puddles instaed ofi the lakeshore. The canvasbeck 
kill continues large , in fact I have looked at more cans than mallards 
this year. Am getting enough birds on the bag tally to mean

    Dear Al: 
 
    I spent some little time on your manuscript, but 
    I would like to put in a little more time on it. 
    Frankly, the repetition must be ironed out, and 
    there is a considerable amount of editing to do 
    before it is in first class shape. The material 
    which you have is too valuable to lose any of its 
    worth through failure in phraseology and arrange- 
    ment. 
    If you are in a hurry to get it back, let me know; 
    otherwise I would like to keep it and do a little 
    work on it for the next couple of weeks. 
 
 
 
                            Yours very truly,

Dear Pauli 
 
I appreciate your lottig me k-w that Senator Wloott likes the trn a 
Deolta, an parti       that he approves Alde's wozr. If he cou1 bahae come

up this suiar, I think his approval would be even stronger. 
 
Nw as to next year's budget.  EAlr has a remr jb with the Illinois 
Natural eistor7 Rvrvqyl, and he is worin, as at Delta, on the physiology
of 
waterfowl. Iliuots, In short, opeA the Delta psattern.     mew's appointment,

howevero, Is an interim appointment, peding the return of ertain men from
the 
a   , and there is no predictin whether or when they will return. Consequently,

there is no predieting whether it will be possible for us to reen  e his

sorrioes next smr. In any event, he is no longer a graduate student# 'out

a salaried research men. and we could hardly hope to got him for the old
rate 
of $100 a mnth. X think It very Imort&nt that he, rather than some other

phsilogist, oonti. the Delta work. I still hope to a        seue glw-aa4-

take sems with Prison. whereby we can get him regularly during the % o 
period. 
 
NeIther   c    o    ano of the Board mts to undertake    a   ventures at

Delta next year, but we do mmt to  ntlme Iler's services. The beet guess

I can make at this time is to set upif possible $200 per month instead of

$100 per month fow a four mouth peiod. This would    t ad *4W0 to the wmwos
budest. 
Confieatially.     abx   an I ha  a hpe of interetin the Carnegie Institute

at   l Sprins Haror in taking on 9   ser Oan  "sIig him to Dlta.  Should

this transpire, his servioes would, of sourse, cost us nothing. 
 
Does Senator Walott have a contacts with the Carnegie Institute? What Rooh-

baum and I la  Is an opprtunity to talk to them. W think we have a strong

448.9 I.e., we can offer them an opportunity for work that is rigt down their

alley at Delta, Mr. Boll is a trustee of thes Carnegie Institute, but we
would 
like to accomplish this thing, and tell him about It afterward., rather than
have 
him pull the wires for us. If the Senator could help us, I would be glad
to 
hame a full statemet prepared aMd testify in person., I would also like to

&razie for them to leek at EMdr in person.

                      Dear Aldot 
 
                                      Senator Walcott spent a few minutes
with 
                      us here at the office yesterday, and in the course
of 
                      the conversation, he expressed his approval of the
work 
                      being conducted at Delta. The Senator, like myself,
was 
                      particularly impressed by the procedure followed this

                      year in enlisting the services of Elder to investigate

                      the physiological problems. We believe that this is
a 
                      most desirable practice and hope that the Advisory
Board 
                      will plan to continue some such arrangement. 
 
                                      I believe that you have advised me
to the 
                      effect that you anticipate that the Delta budget will
be 
                      about the same for the coming year as for the present,

                      namely something over $5,000.00. If you have reason
to 
                      believe differently now, please advise me promptly
since 
                      I have to make up my budget for the coming year in
the 
                      immediate future. 
 
                                      Best wishes.

  Dear Professor Leopold: 
 
         Enclosed is an account of the Petty Cash Fund for 
  the month of August. 
         Mileage for the month-was: 
         926 miles * 4# per mile-----......---......-$37.04 
         In early August I asked William Elder and Peter Ward 
  to visit the Netley Marsh to investigate the botulism outbreak 
  there. The mileage for this trip is included in the above.- 
- All other expenses for the trip were paid-by Elder. I am 
  giving these on a separate shp t which is enclosed. As Elder 
  is now in the States and as I am unable to send money back across 
  the line because of present restrictions, I wonder if payment 
  of these expenses could be made direct to Elder at Box 83, 
  Barrington, Illinoiso 
         The Payroll for the month of September will be as follows: 
         Albert Eochbaum-- 1 month 0 $150.00 
         Peter Ward -       1 month 0  100.00

Dear A.L. 
       I have all but one section of my part of the report typed. Will 
send it to you for review the end of the week. (The hunting season opens

Monday the 22 -- our date of last summer). I have used the same MS we went

over together last winter-- most of it is the same. This is what I would

like to have as the subject matter of th~si first report; My account of 
the Canvasback on the Delta Marsh. Lyle's Ground Squirrel report, The 
review of cloacal sex and age criteria, a short account of of the coot 
by Pete. Pete's short theme concerns reasons for success in the coots in

the face of the same conditions which brought about duck reductions. I 
think you will like it and will be able to round it out into something 
really good. The introduction ,as we decided last summer, will be 
by yourself if you will not be too busy. I will send you an outline of 
dates etc which you will want to have at your elbow when working this over.

 
       In thinking of the tttle T am afraid I am going around in circles.

For a start I would say now;    Delta Bulletin No 1. 
                        First Progress Re-ort of the Delta Duck Station 
 
       I like your mapmmk introduction to Kortright's Pe.       Kortright

had nothing regarding the cloacal characters in his first MS. I believe 
Art told him about it. He asked me for the details; I told him I would 
like to wait until the M.paper was complete as there were still some points

to be cleared up this summer. As yet I have not sent him my MS. He 
nevertheless, prepared his account from what he could find in literature,

which wasnSt very much, then sent it to me for review. What he has now 
is this plus my comments. I shall send him my MS when I feel it is 
what I want to say, but I would rather not be quoted until I am sure of 
what I have to say. My point is that the characters cannot be used without

certain reservations. We have found, for instance that in some species 
the oviduct does not open until the second autumn. The bursa is retained

until the second autumn by a few species. I wanted to be sure of these 
points in my MI before giving it out as a statement. It has been just in

the last month that I have been perfectly clear in my own mind on some of

these points. 
       I am affaid that we did not fulfill our promis6 to Lyle in gaining

as much ground squirrel material this year as we had hoped. We particularly

fell down on nesting. I think you will understand with Pete in the Army 
part of the time and the disease on our hands, how this got by us. Lyle said

that in his absence, you were tying up his report. I will send down what

notes we have on this. 
       The hunting season opens bept. 23 for ducks. &Om.Oct.l-15 for

chickens, October 1-30 for huns,and there are more huns than you can 
 
  

					
				
				
                                -2- 
shake a stick at. The lodge will be closed this year. Mr. Bell may 
come up for a day or sobut he is not planning to open up this year. 
Wonder if you and Starker or your brother might come up. The non-resident

fee is $25.00.   A bit stiff but one gun could be split. The water came up

with a three-day rain and it looks as though we will have some real duck

shooting about the second week in October when the flight usually hits 
us. 
       By the way. The Institute just sent me thý check for Mr. Gilroy.

($80.00) I had already paid it out of this months petty cash fund. I have

now deposited this *80,00 check in the petty cash fund. As the payment 
has already been made I believe this $80.00 should be subtracted from the

petty cash replenishment check which the Institute will send me at the 
end of the month. 
 
                               Sincerely,

Dear Aldoe 
 
                I am just now working through my pile of corres- 
pondence. I note your letter of August 20 relative to the 
publication of a bulletin on the work being conducted at Delta. 
 
                 So far as I know, we are at liberty to call on 
Mr. Carpenter for an amount not to exceed $500.00 to cover the 
cost of the publication of such a bulletin. 
 
                Ultimately, a more complete bulletin should be 
published than is contemplated in the immediate future. I do 
not think that we would be justified on calling on Mr.-arpenter 
for his contribution for the publication of only aDinlehse 
of the work. Therefore, I believe that we should contemplate-e 
raising the money for the publication to be printed in the near 
future from some other source. 
 
                You can see from the above that I am somewhat 
reluctant to call on Mr. Carpenter until we have a more pre- 
tentious offering to make. 
                                                                        
   4- 
                If you do not agree with me on this, please 
do not hesitate to advise me and I will, of course, take the 
matter up with Mr. Carpenter. 
 
 
Best wishes. 
 
 
Very sincerely yours,

Just one little point In your letter of August 1... 
Senator Walcott end Mr. Bell at the meeting last yftr 
were clearly j   satisfied with reprints, either from 
the Trasaction   or the technical Journal* as an outlet 
for the Delta findngs| hence, it wa decided by the Board 
at that time that 6he entire findings would be publishe 
in a special Institute bulletin. The recent discussion 
pertained to the form an finality of the bulletin, but 
the decision to publish a bulletin Is, I think, final. 
My undertanding is that we will call on Mr. Carpenter 
for the $500 to cover the cost. 
Xf I am off the traek on this# please lot me Mw.* 
                           With boeot roa~rdo,
