1880.] 455 [Stone. 
several long gaps in the system; on the up slope from Rumford to 
Milton the kame is continuous and composed of sand and fine gravel; 
near the col of the Woodstock Pass all but the coarsest material is 
washed away, and the pebbles are beautifully rounded, some being 
two, three, and even four feet in diameter and many of them almost 
spherical; and this is the characteristic of the kame as far as South 
Paris. Here it expands into plains, which are for the most part re- 
ticulated as far south as Gray, where they take the form of discon- 
nected ridges or solid plains as before described. 
Length about 105 miles. 
XXIV x. Kennebago Kames. 
These are reported by Mr. Huntington, of the N. H. Geol. Survey, 
as found in the Kennebago valley about twelve miles north of Lake 
Mooselocmaguntic. Connections obscure. 
XXIV a. Andover Gravels. 
The sand and gravel plains about Andover village were brought 
down from the valleys of the West Branch of Ellis River, and of ) 
Sawyer Brook. Part of these gravels are of kame origin. 
Length about 10 miles. 
XXIV b. Locke’s Mills Kames. 
An interrupted series of kames extends from Bryant’s Pond to 
Locke’s Mills. At this point two kame-streams joined, one coming 
from Bethel, the other from the direction of Bean’s Corner and Bear 
River, but kames cannot be traced far in either direction before they 
are lost in abundant valley drift. 
Length 8 miles. 
XXIV m. West Cumberland Kame-Plains. 
A broad rounded plain of gravel is found at West Cumberland, 
and from thence a series of plains, obscurely reticulated, and from 
one half mile to one and one half miles broad, extends westward for 
about four miles. The stream which deposited the western por- 
tion of these plains came down a valley which extends to Gray vil- 
lage, and hence these West Cumberland plains may be a delta of 
System XXIV. The eastern part of the plains may have been thrown 
out by XXIV along a low pass lying just to the west of Walnut Hill- 
XXV. Casco— Windham System. 
So far as now known this system begins in Casco in a low pass 
which forms the divide between Thompson and Rattlesnake Ponds. 
It passes through and under the latter named pond, as well as Panther 
Pond, and thence as a broadening series of kame plains to Raymond
