The characteristic and abaudaut i)la!its of the region are chiefly 
siicli arctic-alpine species as Carex rigicla bigelovii, Geitm radiatum 
peckii, Arenaria groeulandica, Diajiensia lapponica, CastiUeia pal- 
lida septentrional is, and various heaths and willows. Some typi- 
cal Canadian forms are common and generally distributed, while 
a few plants having a still more extended i-ange to the southward 
occur in profusion. Among the former may be mentioned 
Cornus canadensis, Ledum latlfolium, and Clintonia borealis, 
while in the latter category' belong Veratrum viride, Trientalis 
americana, and Viola hlanda. Tlie most noticeable grass-like 
plant found about the summit is Carex rigida bigelovii. This 
forms dense masses of turf wherever a gully or depression among 
the rocks allows soil to collect, and must be of the utmost 
importance to the mammals of the region, forming as it does their 
chief source of food and shelter. 
On comparing the elements of the flora and mammal fauna of 
the summit of Mt. Washington we see certain very marked differ- 
ences. There is but one peculiar alpine mammal {Evotomys 
gapperi ochraceus) , the other species being such as occur also at 
the base of the mountain. On the other hand at least one half 
of the plants are arctic-alpine forms, either restricted to this and 
neighboring mountain tops or found also in the high north. 
Of bird life about the summit there is little to say. The only 
species found breeding above 5,000 feet was Junco liiemalis. This 
bird was common in various parts of the Alpine Garden (5,300 
feet) and among the scrub spruces near the Lake of the Clouds 
(5,200 feet). It was also seen flying about among the rocks near 
the Summit House on the extreme top of the mountain. The 
young were well on the wing at the time of our visit, and many 
were caught in Schuyler traps set for red-backed mice in the 
spruce scrub. Zonotrichia albicollis breeds well up toward the 
head of Tuckermnn's Ravine where its song was often heard as 
we were at work in the Alpine Garden a thousand feet above. I 
doubt whether the bird's range extends beyond 5,000 feet, though
