462 J. D. Dana—“ Kames” of the Connecticut River Valley. 
cut or gorge commencing close by the west side of the cobble- 
stone exposure just described. The gorge (with its carriage 
road at bottom), seemingly divides off a veritable “kame” from 
the terrace west of it; but the beds on the opposite sides of this 
cut so correspond, that there can be no doubt of stratigraphic 
unity. 
The section of, the ‘‘ kame” along this gorge is more or less 
obscured by slides, but not in all parts. It shows, first, that 
the stony beds diminish rapidly in coarseness away from White 
river or to the north. One hundred feet up the gorge, the 
cobble-stones are half smaller and extend up toa height of only 
30 feet above the level of the railroad, or 66 feet above the 
river, and beyond this they continue to diminish. At 400 feet 
up the gorge, the ascending road along its bottom reaches a 
height of 28 feet above the railroad level, and here, in the ex- 
posed section on the east side, there is a bottom layer of sand, 
and above the sand 30 feet in thickness of clay; and this clay 
track and extends inward (westward) to the center of the 
‘‘kame” line. But there is nothing kame-like within it, and 
least of all at its inner extremity. On its north side, it has no 
cobble-stone beds, not even gravel beds; the material is fine 
sand delicately straticulate. On its south side, in the part 
nearest to the river, there occurs, in a large mass that has slip- 
ped down from above, a thin bed of small stones (three inches 
in diameter) with some gravelly and sandy layers below; else- 
where the material is sand. In the inner part of the cut, be- 
sides the fine sand, there is a bed of light-colored clay and 
sandy clay between 60 and 90 feet above the railroad, and 
above this within a few feet of the top, sand and fine gravel. 
There is however one “ kame”-like feature. Upon the top 
of the terrace (here about 510 feet above mean tide), near the 
inner end of the gorge there is an isolated knoll about 30 feet 
high, and of rounded form, which has many cobble stones over 
its surface, some of them 10 inches in diameter—indicative of
