JW dear Mr. Leopold; 
Replyipg to your letter of September 19, 
the young pheasants mentioned in Leffingwell's Pheasant 
bulletin were young birds reared by him from eggs 
supplied by the New York State Conservation Comission. 
I   They were banded and refleased at approximately eight 
weeks of age in fifteen or twenty groups within a 
radius of ten miles of Ithaca, N. Y. 
If you have not already heard, I know you 
will be pleased to know that Gardiner Bump of the 
Bureau of Grouse Control of the New York Conservation 
Conmission have reared over 100 Ruffed Grouse this 
season. The problem seems to be one of sanitation. 
With kind regards, 
Sinoerely yours, 
A. A. Allen, 
Professor of OrnLoology,
