GLACIAL DRIFT. 229 
There are no indications of the passage of this glacier below Bethel, 
so far as I had time to search for them. I did not follow down the An- 
droscoggin on the south side, and the north side only to Bear river, 
though I crossed it at Rumford Point. I found evidences of local action 
down Bear river, in Grafton and Newry, and upon Ellis river in Andover 
and Rumford, as well marked as those along the Blackwater in Andover, 
N.H. On the east town line of Bethel, the striz run S. 4° E., and S. 24° 
E. On Paradise hill, south of the village, the course is S.23° E. These all 
correspond to the common course of the drift in this part of the state. 
Saco Valley. A few points of interest manifest themselves through 
the valley of the White Mountain Notch, which may be regarded as a 
local movement. The mountain east, Webster, shows the course S. 
30°-37° E. On the west, Tom, S. 57° E., Field, S. 50° E., Willey, S. 
42° E., corresponding well with the usual south-east course on the high- 
est summits. Mt. Willard, which is really the head of the valley, shows 
distinct strize, more abundant on the slate towards Field, running S. 23° 
E. In the very Notch, by the railroad, the course is S. 20° E. Under 
the Butterwort flume, close by the railroad, at a small house, are glacial 
lines on a mural surface running with the valley ; and on the south side 
of Mt. Willard the course S. 15° E. was measured. On the railroad, by 
the Willey brook, the stria may be seen from the train on both sides, 
and is thought to be southerly, as it certainly occurs parallel to the valley. 
Other markings down the valley directed more easterly, occur upon the 
north side of Frankenstein cliff. Below Bemis a mural surface shows 
similar scratches over a limited area. No other markings have been 
seen. Mt. Washington river shows an immense cliff of rudely stratified 
material near its mouth, comparable with the similar deposit on Peabody 
river produced by the melting of a local glacier. The immense amount 
of boulders and coarse moraine material just below Sawyer’s Rock sug- 
gests detritus brought down by a local glacier. The tributary Duck 
Pond stream, west of Bemis, shows strize upon a mural surface, pointing 
S. 18° E., which may have been connected with the Saco glacier. The 
nature of the rocks, readily disintegrating, and their obscurement by 
débris and forests, render it difficult to accumulate many facts about drift 
phenomena in it; but enough has been seen to indicate the probability 
of the existence in it of an ancient local glacier.
