Island and Martha’s Vineyard. Narrow ponds, to the number 
of a dozen or more, having the same height with the ocean, fill 
the entire course of these depressions, or occupy their lower 
end next to the south shore. 
The Second Terminal Moraine.—A. later series of morainic 
hills extends along the north shore of Long Island for forty- 
five miles eastward from Port Jefferson to its extremity at 
Orient Point. Their heights are approximately as follows: 
Mount Sinai, at school-house, and Miller’s Place, each about 
150; Noah Jones’ Hill, 1} miles east from Miller’s Place, 200; 
Pine Hill, one mile farther east, 175; Blue Point Hills, one 
mile southeast from last, 150; hills near Wading River vil- 
lage, 150 to 200, the highest of which, at Mr. D. M. Tuthill’s, a 
mile east from the village, commands a very fine view; hills, . 
partly of dune sand, north of Baiting Hollow, known by the 
names of “Horse in the Bank,” Horton’s Bluff, and Friar’s 
Head, about 150; at Northville, 125; Jacob’s, Cooper’s and 
Mattituck Hills, 125 to 150; Manor Hills, extending east from 
Mattituck Inlet, 100 to 150; Horton’s Point, 70; highest 
points for the next seven miles, extending by Greenport, about, 
0; Brown’s Hills, north of Orient, 110 and 160. East from 
the light-house on Horton’s Point, these deposits, though not 
rising in prominent hills except at Orient, are in man aces 
unstratified, with an abundance of large angular bowlders, 
which are of all sizes up to twenty-five feet in diameter. This 
terminal moraine overlies stratified gravel, sand and clay, 
which contain no bowlders; as is well shown in the bluffs, 00 
to 100 feet high at the north side of Brown’s Hills, where the 
very coarse morainic till is five to twenty feet thick, and forms 
the entire surface of these hills) The last two miles of this
