Hill, about 250, and Osborn’s or Bald Hill, 298, the last two 
being a few miles southwest from Riverhead; the East Hills, 
and the range onward to Canoe Place, 150 to 200 feet; Sugar- 
loaf, the highest of the Shinnecock Hills, 140; the Pine Hills, 
150 to 250, reaching their highest elevation three miles south- 
west from Sag Harbor; Stony Hill, a mile northeast from Ama- 
gansett, 161; Napeague Hill, the highest of the Nommonock 
Hills, at the west end of Montauk, 185; the Hither Wood 
in the course of this series of hills. Its area is stated to be 
about 460 aeres; its height, fifty-four feet above sea; and its 
extreme depth, eighty-three feet. The only stream that crosses 
the line of this moraine on Long Island is Connecticut River, 
which rises on its north side and flows southward at the west 
base of Homan’s Hill, its valley being here about fifty feet 
above sea. A few miles farther east, between Yaphank and 
Manorville, the railroad crosses this line on par mer 3 
about seventy-five feet above sea; as also does the Sag Harbor 
ranch a few miles southeast from Manorville. The isthmus 
of Canoe Place, which joins the south branch to the main island, 
is composed of gravel and sand, less than a quarter of a mile 
wide and rising only twenty feet above sea-level. The portion 
of this moraine which occupies the next three or four miles 
eastward is widely famous under the title of Shinnecock Hills. 
Though comparatively low, they have been more noticed than 
other portions of this range, because the traveler finds his road 
winding among their irregular hillocks, knolls, ridges and hol- - 
lows. They are better seen, also, use not covered by 
woods, which clothe the higher hills of this series extending 
from them to the west and northeast. Their material, as of 
the series generally from Harbor Hill to Amagansett, is irregu- 
larly stratified gravel and sand, with occasional bowlders, which 
here vary in size up to a diameter of fifteen feet. The roads 
from South Hampton to North Sea, from Sag Harbor to Kast 
Hampton, and thence to the ae cross the morainic line at 
depressions which are occupied by nearly level plains about 
forty feet above sea. The longest interruption in this series
