Rozlyn, the highest point in the island, thence west south-west, 
through Greenwood Cemetery, Brooklyn, to the Narrows at Fort Ham- 
ilton, and across the south-east part of Staten Island. Prof. Cook, of 
_ New Jersey, has accurately marked its line across that State, in his 
report for 1878. Beginning at Perth Amboy, it bends northward, 
through Raritan, Plainfield, Chatham, Morris, and Hanover, to Rock- 
away, thence a little south of west, to Oxford, on the Delaware 
River, a few miles above Easton. 
6. These terminal moraines resemble, in many respects, what would 
occur if a line of such hills as appear in Boston Harbor were closely 
clustered together, and extended the whole distance mentioned. 
Their summits, however, are not so symmetrical as those of the so- 
called lenticular hills. The width of this terminal belt of hills is 
from one to two miles. Jn this belt there are immense enclosed 
basins, called in Wisconsin kettle holes. They are frequently much 
larger than similar enclosures in the kames. I noticed one between 
Falmouth and Wood’s Holl, that must be a quarter of a mile in 
diameter, and two hundred feet deep. Mr. Geo. W. W. Dove and I 
agreed that the tendency of this moraine belt, on the island of Nau- 
shon, was to break up into alternate long hollows and ridges nearly 
at right angles to the main line. Mr. Upham also has observed 
something like this in Wellfleet and Truro. Nearly everywhere 
where I have observed it, the moraine is covered with large, angular 
boulders, frequently of immense size. Near the Quisset House, be- 
tween Wood’s Holl and Falmouth, I found the boulders beneath the 
surface distinctly striated. In general the composition is something 
like that of the lenticular hills, though not so largely composed of 
compact clay. 
I have been trying to make out that the lenticular hills of the 
latitude of Boston were arranged with some reference to that south- 
ern terminal moraine, but with indifferent success. Still there is an 
approach to continuity from Pigeon Hill on Cape Ann, and a singu- 
lar hill of clear boulders between Rockport and Gloucester, through 
Ipswich, Rowley, Topsfield, Danvers, Peabody, Chelsea, Boston and 
Brighton. (The lenticular hills in Grafton and Spencer are in the same 
latitude.) Then after a belt of five or six miles where they are con- 
spicuous for their absence, there is tolerable continuity again from 
Stratham, seven miles west of Portsmouth, N. H., through Salisbury, 
Amesbury, Greenland, Bradford, North Andover, Andover to Low- 
ell, Mass.; and to an unknown distance south-west. Similar hills are
