Dear King:
In disposing of my notes on the recent trip I find the
following, which bears on a cycle chart for Minnesota. Since it
seemed probable that you and Stoddard would decide to start such a
chart I am sending the material to you.
"Ruffed Grouse. (Chapman) In 1909 were everywhere near
Grand Rapids and south of Grand Rapids.
In 1913 there were many near Pine City and in the
Superior National Forest.
Also high in the Superior National Forest in 1919,
dropping off in 1920.
Prairie Chicken. Said to show a considerable comeback
in Sherburn Co. in 1929."
I know you will not forget the exceptional opportunity offered
by Dr. Roberts' early journals as to high and low points on ruffed grouse
in the early years of his Minnesota work.
When I reach northwestern Wisconsin and if by that time there
appear to be any exceptionally interesting problems to look up in that
region I will let you know my schedule,so that you can join me for a while
if you so desire. I will have plenty of room in my car for us to trip
around together. Possibly some of the ways of getting cycle chart data
could be gone over together in the course of such a trip. I know I would
value your criticism of the methods I have been using and in addition, of
course, would enjoy being out with you.
With best regards,
Yours sincerely,
AIDO I00LD,
In Charge, Game Survey.
