not measured, but cannot be much, if any, more than one hun- 
dred feet above the river. No grooves of the local glacier could 
be found on the north side of Hark hill, though they are beau- 
tifully developed everywhere on the south side of the hill next 
the river. 
On the south-east shoulder of Hark hill is found a morainal 
ridge. It bears N. 20° W., which was so near the direction of 
the flow of the continental glacier that I carefully examined the 
northern end of the deposit to see if it was a “tail” to a spur of 
the hill. It ends on the north at a height by aneroid of about 
one hundred and ninety feet above the river, terminating as a 
steep ridge of loose materials piled up to a height of ten or 
fifteen feet above the surrounding slopes of the hill. Its length 
is about one-fourth of a mile. It is evidently a moraine of the 
local glacier, and is described as such by Prof. Hitchcock. 
Here then at this bend of the river, at the State line, are two 
remarkable moraines lying transverse to the valley and directly 
Opposite to each other. Each begins at a point about two hun- 
dred feet above the river and reaches down nearly or quite to the 
upper terrace of the valley drift. The larger moraine is on the 
south side of the river, and almost in a line with the glacier’s 
axis for a mile or two up the valley. It appears as if the local 
glacier here paused in its recession for a time long enough to 
form a terminal moraine of considerable size. That part of the 
moraine which was within reach of the swollen river would natu-
