Dear Professor Leopold, 
 
      I am sorry to repeive the news in the copy of your 
letter to Mrs. Nice, February 24, that it is unlikely that 
Dr. Elton will accept an invitation to come to the Chicago 
meeting. I realize that this is a disappointment to you 
and a loss to the symposium. However, I hope that you will 
make every effort to carry out your plans for the symposium 
on bird and mammal populations in spite of it. As I have 
mentioned before it is well timed and well located for the 
Chicago meeting and should become the headline item of the 
E.S.A. program even without Elton. I trust you and Erring- 
ton will both participate. We can easily get someone to be 
chairman of the program. 
 
      I am enclosing Hutzel's letter concerning membership in 
A.A.A.S. which is self-explanatory and may be answered at 
your convenience. 
 
                               Sincerely yours, 
 
 
 
                               William A. Dreyer (I
