It occasionally swims ; I know of one which swam across a 

 part of Portage Lake, one-half mile, on a hot summer day, 

 about 1 910, 



Glancomys volans volans. Southern Flying Squirrel. — This 

 species may still be found in some numbers in suitable habitats 

 in the county. They are usually found in woods, although I 

 have found them in houses both in Ann Arbor and at Portage 

 Lake. They nest and live in tree cavities, and in winter are 

 gregarious. In late December, about 1890, in Lodi Township 

 I found 20 or more in a hollow butternut stub. The call is 

 a high, bird-like chirp or long squeak, which I have often 

 heard from the tree tops while in the woods on moonlight 

 nights. 



Castor canadensis michiganensis. Woods Beaver. — The first 

 settlers of this county found this species to be nearly extinct, 

 although dams and old beaver' meadows were very common. 

 It probably became scarce about 1800. Hon. Henry S. Dean, 

 of Ann Arbor, told me that in 1837 at "Gravel Run," a few 

 miles north of Ann Arbor, he saw a dam in good shape, 

 although not used at that time. Remains of other dams still 

 exist. S. D. Allen, of Ann Arbor, told me that in 1835 he 

 -saw a live beaver in the Huron River near Ypsilanti. This is 

 the last record for the county, 



L^pus amcricaniis aniericamis. Snowshoe Hare. — ^This hare 

 was formerly common over all the southern peninsula of 

 Michigan. In Washtenaw County it persisted for a long 

 time in the tamarack bogs, but when these were mostly drained 

 or destroyed the hares became extinct. It was last taken in 

 Steere's Swamp, four miles south of Ann Arbor, in 1875. One 

 was taken in a swamp near Whitmore Lake in 1890. L. D.
