Bear Mr. Brewster: 
Yours of the 18th inst. was received yesterday and the 
"box of "bird skins came hack this morning. I am very greatly ob¬ 
liged to you for your kindness in examining these skins and for 
your opinion upon their relationships. What you say about the 
specimen from Chippewa County confirms the opinion which I had al¬ 
ready formed. The location is in the eastern part of the Upper 
Peninsula and includes large stretches of spruce swamp and heavy 
timber so that the conditions are more like those of northern 
Ontario than elsewhere in the state, except perhaps on the Keweenaw 
Peninsula, from which region I have never seen any specimens. The 
region about Marquette, on the contrary, is more open^ith fewer 
extensive spruce swamps and more hardwood, and while both forms 
might occur there f or an intermediate race, I should not expect to 
find typical togata . The two specimens sent me were said to have 
been killed from the same flock, at all events they were obtained 
on the same day from the same gunner, and one was decidedly rufous 
while the other was very gray. 
I shall make a strong effort during the comming year to 
get adult males from as many northern points as possible. Unfort¬ 
unately the law prevents our buying specimens^, even for scientific 
purposes, and it is difficult for us to collect them during the 
open season and even more so during the summer.
