288 GLACIERS IN THE WHITE MOUNTAINS. 
somewhat inclined towards the road, may be seen lines run- 
ning s. 30° w., or N. 30° £. Many more traces would doubt- 
less be found in this neighborhood if sought for with care; 
as the few recorded were noted without stepping out of the 
common road. 
Thus it appears that while the glacial furrows in the An- 
droscoggin Valley have courses ranging from s. 20° E. to 
s. 80° x., those of the upper part of the Peabody Valley 
range from s. 30° w. to s. 40° w.; making a general differ- 
ence between the courses in the two valleys of over 80°; a 
difference equal to that between the two valleys themselves. 
We may, it would seem, thus conclude that a large glacier 
moved from the neighborhood of Mount Washington down 
towards Gorham; and that another moved from Gorham 
down the Androscoggin Valley, at least as far as to West 
Bethel. 
In the depression between the higher summits of the 
White Mountains, especially between Clay and Jefferson; 
Munroe and Washington, and at the foot of Mount Frank- 
lin, the rocks are rounded and polished from the north 
north-west. A little above the Lake of the Clouds, directly 
in the Crawford bridle-path, faintly defined furrows may 
seen running nearly north and south; this point would be 
about 5,300 feet above the sea, according to the measut™ 
ments of Professor Guyot. These elevated traces belongs 
not to any local glaciers, but to the general ice moveme 
which swept over the whole of New England. 
The White Mountains have been so scarred and tom by 
slides, the valleys so filled with rubbish, and the beds nite 
streams so excessively water-worn, that many of the gl s 
traces have most likely disappeared. Still, this Tes! ini
