Abstract of Paper Read April 4th, 1911. 
Night wandering bat (Lasionyeteris noctuvagans) . 
Brown hat {vespertilio subulatiis. Their food consists of 
small flying insects, active at night, sleeping through the day 
in a sheltered situation; dormant in winter. 
Smoky shrew {Sorex fumeiis). The shrews are the smallest 
of the Mammals, resembling small mice. They are active in 
the daytime as well as at night. 
Northern white-footed deer mouse (Peromys leucopus- 
7iovcBhorcensis. They nest in old stumps, and hollow trees. 
Sometimes an old nuthatch’s nest is used. They are active 
at night, winter and summer. 
Canadian field mouse {Peromys canadensis) is distinguished 
from the deer mouse, by its blunt nose and short tail. This 
mouse is destructive to young fruit trees. They are active at 
night, summer and winter. 
Star-nosed mole {Condylura cristata) inhabits dry situations. 
Its sleeping room, entered by several passages, is situated under 
a hillock. 
Common mole {Scalops aquaticus) is found in marshy 
situations, or near water. The food of both the star-nosed 
and common mole consists largely of earthworms and grubs. 
Red squirrel. Eastern chickaree {Sciiirus hudsonicus gymniciis) 
is active winter and summer. 
Lyster’s striped chipmunk {Tamias striatus lysteri) or ground 
squirrel; is distinguished from the preceding by its smaller 
size and striped coat. Their burrows are deep under ground, 
where they spend the winter. 
Boreal flying squirrel {Sciiiropterus sabrinus) seemingly 
divides the day and the night; as I have frequently seen them 
up till mid-day, but never in the afternoon, and it is known to 
be nocturnal in its habits.
