Professor Aldo Leopold,

Madison, Wisconsin. 
Dear Professor Leopold: 
I am pleased to learn that your students are interested in 
phenology and that you have found Tech. Bull. 686 useful in your 
work. Mr. Price and I derived a lot of pleasure in seeing the 
results appear as the data were analyzed. 
I am not an authority on animal phenology but I can see 
the desirability of such observations being kept parallel with plant 
records. We are not aware of any society or bureau that fostersthe 
keeping of such records and this station is not prepared to maintain 
an activity of this kind at the present time. However, the idea has 
such a wide application that it appears to deserve further conside- 
ration. 
We are taking the liberty of forwarding a copy of your letter 
to Mr. W. R. Chapline, Chief, Division of Range Research, Forest 
Service, Washington, D. C., who is in a better position to state 
the part the Forest Service is willing to play in furthering this 
activity. 
Assuring you of our interest and willingness to cooperate 
insofar as we are able, I am 
Very sincerely yours, 
D. F. COSTELLO, 
Assoc. Forest Ecologist. 
cc-Mr. Chapline
