White-footed mice (_Peromyscus_).--Green (1936) saw a weasel in Gratiot County, Michigan, in May, carrying a _Peromyscus_. Quick (1944:76), in winter, in Michigan, found one dead, probably killed by a weasel. From Washtenaw County, Michigan, Quick (1944:77) examined 294 scats of free-living weasels and found _Peromyscus_ in 189 scats, _Microtus_ in 83, small birds in 20, red squirrel in 3, and hair of weasels in small quantities (probably from the animals which deposited the scats) in 36. He concludes (_op. cit._, 78) that the winter food was 65 to 70 per cent _Peromyscus_, 23 to 33 per cent _Microtus_, and 2 to 7 per cent small birds. Wood rats (_Neotoma_).--A female long-tailed weasel weighing 250 grams was taken one mile north of Kent, Texas, while eating a _Neotoma albigula_ (Davis and Robertson, 1944:263). A wood rat house under observation by Vestal (1937:364) in Contra Costa County, California, was invaded by one weasel which ate two adult wood rats (_Neotoma fuscipes_) and one young. In the same area he saw a weasel in a wood rat nest some months later (Vestal, 1938:5). Three miles east of Reno, Nevada, on May 13, 1936, W. B. Richardson watched a long-tailed weasel carrying a half-grown round-tailed wood rat (_Neotoma lepida_) across a rock slide (Hall, 1946, 192). Harper (1927:303) records three wood rats [_Neotoma floridana_] and two cotton rats [_Sigmodon hispidus_] found dead in the den of a female weasel and her three young in the Okefinokee Swamp of Georgia. Another female and three young approximately half grown were found in the swamp in a hollow pine log. Contents of the den as described to Harper were nearly a peck of wood rats, whole and in pieces; remains of several kinds of birds including robins and quail, and a piece of joint snake (_Ophisaurus ventralis_). Meadow mice (_Microtus_).--Polderboer, Kuhn and Hendrickson (1941), in 1939, at Ames, Iowa, identified "A total of 118 items . . . in 97 winter scats and 48 in the 38 spring scats." Their combined data are as follows: Frequency Percentage Meadow mouse 71 42.85 Harvest mouse 36 21.75 Deer mouse 17 10.23 Mearns cottontail 14 8.42 Short-tailed shrew 9 5.42 House mouse 3 1.86 Tree sparrow 2 1.02 Grasshopper 1 .60 Shaw pocket gopher 1 .60 Least weasel 9 5.40 Unidentified material 3 1.85
