mass is entirely water-laid drift, mainly gravel, and there is slight 
evidence of clay or till. No deep exposures have been made, 
and there are no land-slides, as occur upon neighboring steep 
kames where clay exists. The people in the vicinity report no 
clay or ‘‘heavy soil.” The cultivated fields upon the summit 
show only sand and rather fine, well-rounded gravel. However 
it is possible that the water-laid drift is only a veneer upon a 
mass of till. 
Southward the Hopper mass is continued in the belt of 
kame hills of lesser height stretching past Millers Corners. 
These have an altitude of 900 to 1000 feet, which height is pre- 
served until they terminate against the rising ground to the south. 
With only a fringe of comparatively low knolls, the western 
slope of the Hopper range falls rapidly to the rolling clay plain 
which declines westward toward Mendon and Honeoye Falls. 
Upon the north and northeast a narrow gulf separates the 
mass from the western end of the Fort hill kame range. East 
and southeast a narrow valley intervenes between the Hopper 
range and the lower kames. The latter have an average altitude 
of 850 to goo feet, being mostly water-leveled, and blend into a 
a till or clay plain of the same altitude, flanking the heavy drum- 
loid ridges eastward. These drumloids are in line south from 
Victor, the northern one being known as ‘‘ Boughton” hill. 
North of the Hopper range and separated by a narrow valley 
is a broad, less elevated series which we will name the ‘“ Fort” 
hill range. This name is locally given to the conspicuous, abrupt 
plateau at the eastern end of the range, about two miles from 
Victor, which is historically famous as the site of a stronghold 
and of the defeat of the Seneca Indians by Denonville, in 1687. 
This range has been mostly truncated by static waters, the pla- 
teaus being 850-865 feet altitude and the highest summit 885 
feet (aneroid). The breadth is about one-half mile and the 
length about two miles. The trend is north of west, the western 
end being separated from the northern end of the Hopper range 
by only a narrow gulf. 
Northward toward Fishers the hills seem small by comparison
