Dear Sir: 
There have been made available to the Biological Survey 
a few copies of Mr. Aldo Leopold's recent Report on a Game 
Survey of the North Central States. Knowing of your interest 
in matters affecting our wild-life resources and believing 
that the book will be of value to you, I am inclosing a copy 
for your use. If you already have a copy, you are at liberty 
to pass this one on to someone similarly interested. 
Sincerely yours, 
W. C. Henderson, 
Acting Chief. 
Inclosure.
