THIRTEENTH REPORT. 
5. Tamias striatus Hysteri ( Ricliardson ) . Lyster’s Striped Chip- 
munk. — This species is even more abundant than the red squirrel, for it 
is not, like the latter, confined to the timber. It could be seen and 
heard almost anywhere where there was enough shrubbery to furnish 
coyer. The individuals were not in the least shy. One started to climb 
over one member of the party while he was standing motionless watch- 
ing for birds. Another student succeeded in taming a pair so that 
they came regularly into his tent to eat from his hands and pockets.

G. Marmota, monax mo wax (Linnaeus). Woodchuck. — Woodchucks 
were reported to occur around the farm meadows east of Douglas Lake. 
The writer who worked in the woods and “pineries” more than else- 
where was unable to find any very good records beyond the reports of 
the farmers, though an occasional old burrow left little doubt of their 
presence.* 
7. Sciuropteris sabrinus (Shaw). Hudson Bay Flying Squirrel. — 
This species was reported by woodcutters to be very plentiful but all 
efforts to secure specimens were without success. In talking with lum- 
bermen, the writer learned that it is not unusual for men to cut down 
hollow trees in which ten or more flying squirrels live. This points 
toward gregariousness at least during hibernation. Several were seen 
at night playing about in the tops of low trees and making long flights 
from one tree to another. 
A nest was found not over nine feet from the ground in a rotten snag 
about eight inches in diameter. Members of the Biological Station dis 
covered a family of flying squirrels in this stub during the summer of 
1909, but in 1910 it had been abandoned. The nest was examined and 
found to be made almost entirely of wood fiber or inner bark shredded 
very finely. 
S. Peromyscus leucopus noveboracensis (Fischer). Northern White- 
footed Deer Mouse. — This and the following species are very well repre- 
sented around Douglas Lake. White-footed mice are so abundant that 
it is difficult to catch any of the rarer species of small mammals, for 
one is quite sure of finding his traps filled with these wood mice.
