The 3f,unuscon(i Islands. — Taijlor. 27 
of the highest beach is about 280 feet above lake level, and 
the top of the hill nearly 400 feet. 
At the time of our visit, Mr. Webb had just dug a new well. 
The earth thrown out was composed of sand, gravel and peb- 
bles, with a few small boulders, all very clean and nearly all 
well rounded. The well was sunk into the sandy plain to a 
depth of 32 feet, and tough stony clay was penetrated two 
feet at the bottom. The depth of this characteristic l)each 
deposit is rather surprising in such a situation. It must have 
been entirely the work of waves that sorted the sediments out 
of the glacial drift and deposited them there. For when the 
water stood at that level there was no stream which could 
have been a contributor of sediments. The hill above the 
beach is of stony drift with a large portion of tough yellow 
clay. Apparentlj?- the whole mass of the beach has been gath- 
ered from drift cut out of the hill. This necessarilj'^ implies 
along period of wave action. The highest beach was crossed 
again as we returned at the base of the hill about a mile and 
a quarter east of the Italian settlement. After passing nearly 
two miles over the top of the ancient island, first east and 
then south, the road descends and once more crosses the highest 
beach in an open wood. There are several low sandy ridges 
at that place, faint and broken, but lying in parallel lines on 
a broad gentle slope toward the south. This is the first point 
reached on the ancient island on going from Hessel and is a 
little less than four miles from that place. The road extend- 
ing farther north crosses the island at a jjlace where it was 
comparatively low. 
Between Hessel and the middle Munuscong the marks of 
submergence are ver}'' plain. There are three broad terraces, 
two with high bluffs comparatively fresh and abruptandeach 
facing over a swamp on the back part of the terrace next 
below. 
Going north from Hessel there is first a moderate rise from 
the shore to about 20 feet within a hundred yards. The sur- 
face is very stony and soon becomes swampy, with many fair 
sized boulders, apparentlj'- all glacial erratics. The ground 
continues with this character for nearly two miles to the foot 
of the first bluff, rising gradually to its base, where the hight 
is about 100 feet above the lake. The swamp is broken in
