farther south, the high river terrace consists along its eastern 
margin of very coarse gravel, and is Meg eee ‘therefore to

I found this ridge east of Ascutney Pond to consist mainly 
of loamy material, or sandy loam, like the terrace west of 
Windsor, with little gravel and that chiefly over its upper sur- 
face or in an upper layer. But directly west of the Pond there 
is a terrace (not referred to particularly by Mr. Upham) whose 
material is made up largely of coarse gravel, in part cobble 
stones, and coarsest in its upper layers, which 1 in this portion is 
as much entitled to be called “kame” as that “ta mile and a 
half farther south.” This terrace rises westward to a level plain 
at 448 feet above the sea-level, and then another at 480, and this 
last rises to 525 feet, which is the height given by Upham for 
the possible “kame” east of the pond. Its gravelly character 
continues, but diminishes northward. 
no evidence whatever that the eastern portion of the 
terrace was a “kame,” that is, a part separate in time of 
origin from the rest ; the evidence was all against such a con- 
clusion. Moreover there was an abundant source at hand for 
the amount of coarse gravel and cobble stones; for Ascutney 
or Mill Brook, rising in northwest Reading, flows with rapid 
descent by the north side of the lofty Ascutney Mountain 
(3320 feet), and would have been a great transporter from the 
drift-covered country it drained. The position of the stream, 
and its relation to the southward- at ane Connecticut, account 
for the distribution of the “kame” material or coarse gravel 
of the Windsor region, including that of Windsor alla men- 
tioned by Mr. Upham, and also for the isolation of the ridge on 
the east side of the pon 
Two miles north of Windsor a kame is entered on Mr. Upham’s 
map. Much coarse gravel here makes the outer or westward 
portion of the upper terrace, which is by the. map 500 feet 
above the sea-level. Besides coarseness of gravel, I saw no 
evidence of a kame, that is of any deposits that were distinct 
from the terrace in original os ae A brook comes from

Hartland station, 43m. north of Wincor —At this place stands 
the “kame” ridge represented in Upham’s section reproduced, 
on page 456, of which he says: “ At one place, east of Hartland 
depot, this plain (that of the upper terrace) bas been swept 
away from both sides, and the kame forms a conspicuous steep 
ridge 125 feet in height [above the depot plain, 240 feet above 
the river]. herever it is exposed, it is readily recognized by 
the pebbles which strew its surface, and which are very rarely 
found in the ordinary modified drift of the valley.”
