       In lower animals the first two are out. In mammals traditions 
may be carried by 3 and 4,record and action. The game trail, for 
instancepis a record. And a given individual need never have seen 
another of its kind follow the trail to follow it himself. In birds, 
tradition is carried largely through movement, but there are the *man* 
occasional traditions handed down by record. For instance, the 
nest structure in Ospreys is probably a valid example of a tradition 
handed down by record.   In some truly terrestrial species trails, as 
in mammalsiare records. But one must be careful. For instance the 
same hedge-row may be used by many generations of pheasants as a trail. 
But they follow the trail because of their innate attachement to cover 
rather than because of any record left behind by previous generations. 
 
       Working with it in these terms, I believe "tradition"is
the 
proper word, but if you can think of a better one it would be much 
appreciated. 
 
       I was aware that Ewrington and Fred had used tradition in terms 
of quail behavior, but I cannot yet find, although I have not yet 
given a careful review, where they defined tradition nroperly or 
used it precicely. The fact that covey-size should be attributed to 
tradition, I think, suggests that they were not entirely clear as to 
the meaning of tbe term. 
 
       My liscussion of the subject, all building from the lakeshore 
passes, approaches book-length volume in itself and I have not yet 
started to review the literature, so that I do not yet know buum* 
what it will look like when it was finished, I was interested that 
Rowan should find some points in his own work now explainable in 
terms of tradition.   Indeed, in and out, around and about, it seems 
that traditional behavior plays a much more Important role in bird 
behavior than one would expect at first glance. But the first thing, 
which I an doing now, is to try to find out what the tradition is and 
how it operates and I still have a lot of stuff to sort around before 
it will straighten itself out. In the discussion, I am not starting 
right out with the subject, but building up to it through a careful 
discussion of all the elements msppm upon which the tradition must be 
built. At least I should know more about birds when I get to the 
end of it than I do now. 
 
       Glad to hear about Art and the rest. While I would have been 
happy to have had Bob up here this summer, I think It best to wait 
until we are open, which I am sure will be next year, before bringing 
up any students. Bob knows his way around and would get a good deal 
from being here by himself. But half of the station here is the place, 
and half of it is what is going on. And I would rather not bring up 
any stddents until we am have the crew for a real schedule. When 
we are on the move again, I am anxious to have one of your fellows each 
year; will leave the selection to you. I am also anxious for you to 
get up her fo'r a spell the first summer., or, if you can make it, for 
the spring flight which you have not yet caught.
