Jumping Mouse ; Labrador Mouse. 
The Jumping Mouse is common in many parts of the Adiron- 
dack^, as well as in the surrounding country. It feeds upon 
beechnuts, and various seeds and berries. 
Within the Wilderness it is most often observed in the tangled 
borders of low shrubs that surround the lakes and beaver meadows; 
while beyond the confines of the region it inhabits both the clear- 
ings and woodlands. It delights in grain fields, and in meadows 
of tall waving grass, where it finds abundant food and can readily 
escape its most active enemies. But when the time for haying and 
harvesting arrives, the Mice are suddenly deprived of their accus-

stacks of grain. By quickly overturning these, they are confused 
and frightened and may be captured with comparative ease. 
When stationed to watch for deer, on the borders of our Adi- 
rondack lakes, I have often remained in one place during the 
greater part of the day. Seated, sometimes on a log that crossed 
a narrow belt of marsh along the shore, sometimes on the mossy 
slope of a well-wooded knoll hard by, and hidden by the dense 
frontage of undershrubs, or by the more open shelter of a slender 
tamarack, I have learned much that fills these pages. Encroaching 
upon the very water’s edge is a net-work of wiry bushes, repelling 
the canoe that attempts to land. It consists chiefly of the leather 
leaf ( Cassandra calyculata ) and sweet gale (Myrica gale), with 
smaller quantities of the wild rosemary ( Andromeda polifolia ), 
meadow sweet ( Spircea salici folia), and swamp laurel ( Kalmia 
glauca). Adjoining this is a strip of sphagnous bog which supports 
a luxuriant growth of the curious pitcher plant, interspersed with 
straggling cranberries. Careful search may reveal the insect-eat- 
ing Drosera , as well as several rare species of orchids. Where the
