part I examined), was very stony near the river, while mostly 
free from stones on the side toward the hills. 
On the opposite or western shore of the Thames, at Mont- 
ville, six miles north of New London, where the terrace is one 
half higher, the facts are even better testimony to the same con- 
clusions. The stony beds occupy a large part of the formation 
in a bluff close by the river between the shore and the railroad 
an upper stony stratum along the valleys. West of Ludlow, the 
upper stratum of the high terrace on the south side of the valley 
was coarse stony, while below the beds were mainly of sand. 
At Sutherland Falls, on the Otter Creek (or River, as it should 
be called), where fine sand was the main constituent of the for- 
mation—being fine enough for use in the marble mill—the 
upper portion for 8 to 20 feet was very pebbly, the pebbles 
mostly half to one inch in diameter. Just north of Pittsford, 
on the high terrace of a branch of Otter Creek, there is a coarse 
upper bed; and one still more coarsely stony on the terrace 50 
feet or more below the highest, while the beds below were 
comparatively fine; also south of Rutland, in the upper part of 
the high eastern terrace of Otter Creek valley, especially near 
the junction with the valley of Cold River, and also with that 
of Mill River, west of the gap passed through by the railroad 
to Cuttingsville. 
Professor Hitchcock, in his Report on the Geology of Massa- 
chusetts, makes the general statement that the material of the 
that there were transitions from gentle to rapid movements 10 
the waters] and then, above, the clay is absent, and “the sand 
becomes coarser, until, at the top, frequently small pebbles are 
found, and other evidences of agitation in the waters.’ 
rapid melting of the disappearing ice, it must have been thus 
universal; for the rapid melting would have been general.
