frequently visited by the buffalo, On second thought, I remember that in

Houserook valley, Arizona, observations indicated that while the buffalo

came to water, they did not cae every day. Apparently several days elapse

depending upon conditions, 
Your letter directs attention to an important subject concerning 
which our information is very incomplete. As I have already pointed out 
my own observations have indicated that one should be careful in Making 
definite statements as the water requirements of the same species un- 
doubtedly vary at different times and under different conditions. 
Sincerely yours,
