A peat meadow occurs on the mountain, half a mile west of Round 
pond, five miles southwest of West-Point, on land of Mr. Wilkins, 
and contains 10,000 cords. 
A small peat bog was seen between the limestone ledge and Duck- 
Cedar pond, in Warwick, and may contain 4,000 cords. A peat bog 
was seen near the Patterson mine, containing probably 5,000 cords. 
Another near the Crossway mine, containing 30,000 cords. 
Another east of the SterHng mine, containing 50,000 cords. 
Another, of 60 to 100 acres, was seen in the valley of Smith's clove, 
between Wike's and Galloway's. It contains probably 200,000 cords. 
A peat bog lies west of Townsend's ore bed in Canterbury, and con- 
tains 10,000 cords. 
In the slate and graywacke region of Orange county, peat is every 
where abundant, and the localities are so numerous that it would be te- 
dious to enumerate them. The drowned lands, the Graycourt meadows 
and the Black meadows are the most extensive of these deposits. The 
former marsh is most extensive, and contains 17,000 acres. At a low 
estimate, there must be 25,000 acres of peat bogs in Orange and Rock- 
land counties, that have not been estimated, and we may calculate, in 
round numbers, that they contain 25,000,000 cords of peat. 
The aggregate cords of peat before enumerated, is 1,140,000 cords, 
and the total estimated amount of the peat in Orange and Rockland 
counties may be put at 26,140,000 cords, or about 72,000,000 chal- 
drons. 
Marl. 
No fresh water shell marl was observed in Rockland county: Dr. 
Horton found it abundantly in the peat bogs in the slate formation of 
Orange county, but the quantity has not been estimated, from the want 
of sufficient data. It is hoped that our farmers will make a proper tri- 
al of this material on their lands. The reader is referred to Dr. Hor- 
ton's report on Orange county, in the appendix to this report, where 
the use of this material as a stimulant manure, is discussed. 
Tertiary Deposits. 
The tertiary deposits of Rockland and Orange are similar in compo- 
sition, texture and superposition, to those of Putnam and Westchester 
counties, and which have been described. One of these deposits ex-
