Narrow flats extend along the shore in several places between West- 
Point and the base of Butler-Hill, and a broad one extends from near 
Cornwall to Newburgh. At New- Windsor, a long wharf is built out 
partly across the flats, but large sloops cannot land there except at flood 
tide. A few acres of pebbly alluvion have been formed at the mouths 
of two small streams that empty into the Hudson at Washington's val- 
ley, about one mile above West-Point. 
Salt Marshes, 
A salt marsh of several hundred acres extends from near the landing 
at Dobbs' ferry to near the long wharf at Tappan Slote. Large quanti- 
ties of salt hay are made here every year. 
Another salt marsh of 200 acres or more extends from Grassy-Point 
up the Sampsondale and Mimshecongo creeks to near Haverstraw. 
Another small one is west of Stony Point in Rockland county. 
Another of several hundred acres extends from about one mile south of 
Fort Montgomery, between Waggon's islands and the main land to 
within one mile of Dunderberg Point, near Caldwell's Landing in Rock- 
land county. 
Another occurs at the mouth of Murderer's creek, in Orange county, 
between Cornwall and New-Windsor. 
These marshes all produce a fine crop of salt hay every year. 
Peat. 
Several of the salt marshes contain peat, but that which I saw is 
fibrous, and of inferior quality. That of finer texture and quality may 
probably be found at a depth of four or five feet. A moderate estimate 
of peat of second quality in these salt marshes, would be 500,000 
cords. 
A peat bog of about 40 acres was examined by Prof. Cassels, about 
one mile south of the Long clove, in Rockland county. It is on land 
of Isaac B. Van Houten. It is supposed to have a mean depth of six 
feet, and may be estimated to contain 40,000 cords. 
Another is in the valley of the Hackensack river, about two miles 
west of Nyack, and contains about 50 acres with a mean depth of six 
feet, and may be calculated to contain 50,000 cords. 
Peat, a few acres in extent, was observed by Prof. C. at the north 
end of Rockland lake,perhaps 5,000 cords.
