So far as my own experience goes I have never taken a specimen 
in woodland, or under stump, brush-heap, or other cover than such a 
temporary one as a shock of corn or grain, and even here one is quite 
as successful if traps are set in the rows between the shocks as if set 
under them. Others report their nests under boards, fence rails, 
logs, etc., but the only nests that I have found that were undoubted- 
ly of this species, were in burrows in open fields. The burrows are 
small, about 2 cm. (.8 in.) in diameter. They descend perpendicu- 
larly about 10 cm. (4 in.), then run horizontally, for perhaps 50 cm., 
to the nest. This is composed of nibbled straw or grass. They 
store up seeds and grain in these burrows. They do not hibernate, 
but are certainly more or less active all winter. 
An examination of a limited number of stomachs indicates that 
when seeds, grain, fruit, and other available vegetable food is 
present, their diet is varied but strictly vegetarian. Specimens 
taken in the center of large, well-cultivated corn fields, however, 
where there was little vegetation except the young growing corn, 
had resorted to an insect diet. While they undoubtedly do eat 
grain, still, even when that is present, it constitutes only a part—and 
apparently the smaller part—of their food. In illustration of this, 
I may mention a nest found in the stubble of an oat field which con- 
tained a store of grass seed but no oats. Again, the stomach of a 
specimen taken in late fall in a corn field where there was abundance 
of fallen corn, showed on examination that 25 per cent. of the con- 
tents was undigested seeds of a ground-cherry (Physalis lanceolata) ;
