No. 275.J 159 
Several of these lakes, in the purity of their waters, and in the beauty 
and magnificence of their mountain scenery, vie with the celebrated wa- 
ters of the north of England. 
Our springs are numerous; a few are believed to be medicinal waters; 
some of them will be presented to the analyst of the survey. 
The spring and well waters of the county are considered good; but in 
all parts underlaid by graywacke and slate rocks; much of the water is 
^an^ from containing a salt of lime in solution. This is probably de- 
rived from the rocks, or the stratum of blue marly clay so extensively 
spread on them. 
PEAT. 
In the drowned lands, several thousand acres are covered with this 
substance; it is from three feet to several yards in depth, and on trial 
proves a good fuel. 
The Greycourt meadows, lying in Goshen and Blooming-Grove, con- 
tain 500 acres of peat, several feet in depth. It exists in great abun- 
dance in Warwick, Minisink, Goshen, Monroe, Cornwall, Blooming- 
Grove, New-Windsor, Newburgh, Montgomery, Hamptonburgh, Craw- 
ford, Walkill and Mount Hope; all the towns in the county except 
Deerpark. In this latter town the quantity is small. The quantity in the 
county is unusually large in proportion to its extent, perhaps as much or 
more so than any other county in the State. It would require a great 
amount of time to ascertain the number of acres. It is perfectly inex- 
haustible. If its consumption for fuel ever becomes as general as it is 
in seme parts of Europe, the Greycourt meadows and drowned lands 
would prove a source of immediate revenue to their proprietors. 
ERRATIC BLOCKS— BOULDERS. 
These are found in the county in the greatest profusion. Most of 
the surface is thickly dotted by them, and in many places they are so 
numerous as to prevent cultivation. Under this term, however, it is 
not intended to comprehend any rocks or stones, except such as have 
been removed to considerable distances from the place of their formation. 
Over the whole surface, from the Highlands on the southeast, to the 
Shawangunk mountain on the northwest, perhaps nine-tenths of the 
loose stones are graywacke. Many of them are unlike any rock of this 
description in the county, while others resemble and no doubt were bro- 
ken up from the layers upon and near which they now lie. The paren.
