We found a flock of about thirty robins near the head-waters of the 

 Madison Eiver, Wyoaiiug- Territory", on the 6th of September. The snow

 255) — seemed to be moving southward. They were quite abundant on 

 Snake River during the latter part of September. At all other places 

 on our route robins were seldom met with.
