300 General Notes. [ April, 
covered with ordinary glacial till, with the exception of a mass of 
loose morainal materials lying in the woods a short distance east 
of the brook. A number of white birches and poplars led me 
into the thicket under a suspicion of kames, and thus I stumbled 
upon this deposit. Its southern portion (it is separated into two 
parts by a depression) consists of a ridge from five to fifteen rods 
wide and rising from ten to thirty feet above the surrounding 
slopes of the hill. Here are some granite bowlders, closely 
resembling, if not identical with the outcrop of gneiss found a 
short distance west of here, near the river, The northern portion 
consists of a V-shaped mass with the apex south, It is com- 
posed of two ridges making the angle of 60° with each other, 
which are connected on the north by an irregularly curved ridge, 
the whole enclosing a shallow funnel or “potash kettle,” Of 
these the western ridge is prolonged somewhat to the north of 
the cross ridge in the form of a row of conical hillocks which 
reach down nearly to the upper terrace of the river valley. This | 
western ridge is nearly in line with the southern ridge first de- 
scribed (perhaps they are really one ridge), and both bear nearly 
due magnetic north, thus crossing the State line obliquely. From 
the eastern ridge a short spur juts to the south. The northern 
end of these ridges must rise fifty or more feet above the under- 
lying hill. The ridges all slope outward in all directions, often 
as steeply as loose materials will lie. 
By aneroid the height of the ridges above the river varies from 
180 to 200 feet, and perhaps there were places a little higher than 
those measured. In places the materials show signs of water- 
wash, with a loose structure as of gravelly upper till. Along the 
south bank of the Androscoggin are many morainal masses left 
by the great glacier, but this is evidently a very different deposit. 
Considering the shape of the mass, its situation, its height, its 
materials and the steepness of its slopes, I regard it as a moraine 
of the local glacier. It is one-third of a mile long and at one 
point is about one-eighth of a mile wide. 
The significance of this moraine becomes more evident after 
examining the north side of the river opposite. Here a high hill 
called Hark hill, stands far out into the valley in the angle be- 
tween the Androscoggin and a stream that comes in from the 
N. N. W. Hark hill is separated from the cliffs that. form the 
northern walls of the Androscoggin valley toward the north-west 
by a low valley in which is found an extensive moraine. This 
deposit ends on the east and north-east in a steep bank or bluff 
from twenty to forty feet high, overlooking the interval of the 
lateral stream above mentioned. It contains many angular 
bowlders and sometimes an angular gravel, as if little water worn. 
This deposit is not valley drift, and for the most part does not 
appear to be ordinary till. I marked it as a lateral moraine of 
the valley glacier, though not very positively. Its height was
