ered by a nearby pure stand of white bircli under which mosses and 
liverworts ( F unarm and Marchantia) grow in the greatest abundance. 
Back of this, there is a sharp rise of ground covered by dense hard 
woods, mostly maple. The trees gradually become smaller as one leaves 
the lake and they are finally replaced by a dense growth of under-brush. 
Here were found white-footed mice, chipmunks, and red squirrels in abun- 
dance; and less frequently flying squirrels, raccoons, and deer. 
Station III. For the third station a point of land northeast of the 
station on the shores of the lake was chosen. At this place, a strip of 
pine fifty feet wide extends along the shores of the lake. Back of the 
pines are poplar and white birch and a slight depression in which wil- 
lows grow. At this place red squirrels, chipmunks, white-footed mice, 
hares, and the short-tailed shrew were found, and both foxes and deer 
came almost every night to the beach at this point. 
Station IV. A swamp near the “Big Springs” was selected for the 
fourth station. Cedar, balsam and spruce were the principal trees; 
under these was a very thick soft carpet of sphagnum moss. In this 
place, white-footed mice, chipmunks and one Cooper's lemming vole were 
taken. 
Station V. The fifth station selected was the hardwood forest north 
of the lake. Along the water’s edge were found overhanging birches 
and back of this was a natural terrace on which almost nothing but 
hemlock grew. Back of the hemlock, was a virgin forest of hardwood in 
which a. few scattering hemlocks were found. At the west end of North 
Fishtail Bay, there was a piece of low ground covered with cedar, birch, 
and ash in abundance; cedar being the most plentiful. It was in this 
cedar swamp that the only specimen of red-backed mouse was taken. 
This was the best mammal station of all and the farthest from the 
Biological Camp. Records or specimens of the following forms were ob- 
tained : deer, red squirrels, fox squirrels, black and gray squirrels, fly- 
ing squirrels, muskrats, porcupines, red-backed mice, skunks, red foxes, 
raccoons, white-footed mice, bats, and hares. 
The location of the stations is shown on the accompanvincr sketch 
map.
