examined. In some cases, they are so numerous and so large that 
tliey may be seen in the gravel banks from the passing tr.iins ; it 
being understood that the trains on the Cape do not travel at 
lightning speed. The cut at North Truro station may be espe- 
cially mentioned, as it is here that the traveller leaves the railroad 
on the way to Highland Light. At the base of the cut, few 
facetted pebbles were found, and these had probably rolled down 
from the top, where they were common. At the surface, the 
gravel beds were thinly and unevenly covered with blown sand. 
It was manifest that no conditions different from the present, 
except the absence of vegetation, were necessary to account for 
the facetting at this point. 
The south and east shore of tiie Cape is frequently cut by the 
waves, forming a low sea cliff. It is such a cliff that rises along 
the eastern side or "back" of the Cape, to heights as great as 
one or two hundred feet, as at Highland Light. At that point, 
pebbles were found at various depths below the surface, but 
none were facetted. At South Yarmouth, on the southern shore, 
where I had much more deliberate opportunity of examining the 
shore cliff, which there measures at most only ten or fifteen feet 
in height, facetted pebbles were cotnmon down to depths of two 
or three feet below the original surface. Allowance is made in 
this measure for the frequent covering of dune sands, which 
often rise ten or more feet above the marginal surface of the gravel 
plain ; the contact of the two being easily recognized by the soil 
belt. During the j)ast summer, I have repeatedly examined 
this cliff at different points, always succeeding after a brief search 
in finding facetted pebbles in place ; and in all cases they lay 
with the cut edges uppermost. They are also found in the 
])ebbly belt along the water's edge at low tide, where they have 
been presumably carried from the cliff by the waves. 
The highest cliff of stratified sands and gravels on the southern 
shore is at Succonnessett Point, between Falmouth and Cotuit. 
The bluff here rises twenty or thirty feet above sea level. The 
occasional pebbles scattered through the greater part of this 
section were not facetted ; but in the uj^per eight or ten feet, 
wliere pebbles were common, many carved pebbles were found, 
and, as before, they lay with the facetted side uppermost. The 
greatest depth at which a pebble with distinct facets was found 
was about nine feet beneath the surface. Many carved pebbles
