460 J. D. Dana—‘Kames” of the Connecticut River Valley. 
In Hartford, Vi., at White River Junction, 44 miles north of 
North Hartland.—On the west border of the Connecticut about 
White River Junction, or at the mouth of White River, there 
is a short “kame’’ according to Upham’s map south of this 
river, and one, a mile and a half long, north of it. The White 
River valley is here very broad, like a piece of the Connecticut, 
and as it rises westward but slowly, it opens to view a portion o 
the Green Mountain range, which is the chief source of its waters. 
The Connecticut valley terraces of the region are high—not far 
from 180 to 235 feet above the river, or 510 to 570 above mean 
tide level; but that to the north, owing to the retreat in the 
hills is much the most extensive, and hence the greater length 
of the northern of the two “kam 
The southern “kame” commences within a few yards of the 
railroad eat and hotel, where an excellent section of it is 
exposed to view. The pitch of the slope toward the Connect- 
icut is about 40°. The structure is well-bedded throughout. 
The layers consist of cobble-stones, finer gravel and coarse 
sand. ‘The coarsest cobble-stone layers are below, and some of 
the rounded steaks from them are one to over one and a half 
feet in diameter. Other cobble-stone layers, less coarse, occur at 
different levels above, alternating with an increasing thickness 
of gravel; and toward the top, which is near the top of a ter-

Upper part of the section of the “ kame. i 
race-plain, the material is finer gravel and sand. Fig. 4 shows 
the position of the cobble-stone beds in the upper half of the 
section. The beds are not continued through the figure because 
in the western portion of the section the layers were mostly con- 
cealed by slides; but it was manifest from the few and smaller 
stones on the surface that there was a marked diminution in 
coarseness to the westward even in the first LOO yards. 
The cobble-stone beds exposed to view in the section stop 
short off below at a level about 20 feet above the level of the 
railroad track, or 56 feet above the river (low water), and un- 
derneath occurs a bed of coarse sand, having the flow-and- 
plunge structure well marked. A section of the same sand-bed 
was observed 70 yards to the south, evincing that it is = a 
local deposit. But the depth to which it was exposed w 
hardly 8 feet ; and it may be that there are other stony “pido
