in the county when the first settlers arrived, and continued common for many years. It quickly learned to adapt itself to civilization, feeding by night where it formerly fed by day. Some early settlers report much damage done to gardens and crops, of which the deer soon learned the location. The last deer known to me in the county was seen in Saline Township in 1875 by William Gordon, who reported it to me at the time. Covert[5] records one seen in the county in 1879.

Hypothetical List

The mammals included in this list have been reported as occurring in Washtenaw County, but I can find no specimens with authentic data nor descriptions satisfactory for identification, and consider the records doubtful.

Rattus rattus rattus. Black Rat.—Covert[6] states that the species is "very rare. I have but one specimen, which was caught at the Michigan Central R. R. Depot."

Mustela allegheniensis. Least Weasel.—Covert says, "The only specimens of this mammal I have had were brought in this winter" (1881). I have not been able to find these specimens, which were doubtless small females of Mustela noveboracensis.
