232 SURFACE GEOLOGY. 
Between Greenfield and Bennington are rows of boulders on the south-west side of 
a large lenticular hill. 
Crotched mountain in Francestown and Bennington may be taken as a good example 
to illustrate the presence or absence of this class of deposits. An attempt to makea 
thorough examination of this elevation was frustrated; but evidences of the moraines 
were seen on the south-west side, consisting of many large, rough blocks and ridges 
on the north-east side of Whittemore pond. Similar blocks occur on the road nearest 
the mountain on its south side. The north-east slope of this elevation is smoothed, as 
if there had been a sliding over the till; but I have not seen the nature of the ground 
at the very base. As it appears uncultivated when seen from a distance, it is probable 
that so much rubbish has been pushed into it from Crotched as to make the land diffi- 
cult of tillage. 
The north side of the New Durham and Brookfield Moose mountain is thickly strown 
with large boulders of granite and schist, obscuring the ledges. 
Various evidences of local sliding appear in the city of Manchester. One is at the 
corner above Brook street. Three layers appear in an excavation, the two lowest ap- 
parently resembling the upper and lower till. The uppermost—of a lighter color—may 
have slid down the hill about the time of the termination of ice action. It is a material 
that runs like porridge when wet. Other similar cases have been removed in grading 
for new streets. The north-west side of Company hill for over a mile shows many mo- 
raine-like windrows parallel with the ridge. These contain more or less boulders, and 
are properly referable to this latest action. Perhaps these moraines should have some 
connection with the north-west course across the rock near the Amoskeag granite 
quarry. On the south-east side of this hill, back of the granite quarries, as we pass 
the pest-house on Bridge street, is another local moraine. Bald hill, near the east line 
of the city limits, furnishes other illustrations, there being two north and south lines of 
moraines upon its east side. On the south slope of this hill are numerous blocks of 
granitic gneiss, situated in a north and south course, reaching nearly to the railroad. 
One of them is 20 feet square. These seem to have been derived from Bald hill. Other 
lines of moraines occur at the south-east base of the Reservoir hill, where the frag- 
ments are angular. 
In Grafton are high hills extending from Prescott’s easterly along the Springfield line. 
A brook flows easterly along their base, turning at an acute angle by a small pond, and 
entering Smith’s river at Grafton station. Within this acute angle are piles of drift 
parallel with the easterly hills south. These may be the rubbish sliding down from the 
south across the brook. 
In Chester, two hills near each other seem to have crowded this loose detritus into 
the valley between. First is the gneiss hill in the north part of the town; and we find 
a line of blocks on its south-east side from Wm. S. True’s round to near North pond, a 
distance of two or three miles. There may have been additions to the moraines from 
the smooth hill south, upon which Chester village is situated. 
In Deerfield, the direct road from Candia to the Centre across a long ridge in the
