A bed of limestone containing brucitej serpentine and asbtstus, is as- 
sociated with the bed of magnetic oxide of iron on Mr. Tilly Foster's 
farm, two and a half miles southeast of Putnam Court-House. 
Above Patterson in Putnam county, is an extensive bed of limestone. 
Many hundred acres in this valley are underlayed by limestone. It is 
quarried for lime, and forms a superior article. Sixty cords of wood 
are consumed in burning a kiln of 2,000 bushels. The price of this 
lime is 50 cents per bushel. Much of this stone seems well adapted 
for a building stone. Some of the rock contains beautiful tremolite. 
A bed of impure limestone crosses the Cold Spring turnpike near 
Haight's tavern, in Phillipstown, five miles northeast of Cold spring; 
another bed is supposed to cross the road one-half mile north of War- 
ren's tavern in Phillipstown; another bed crosses the road on the hill 
near Indian brook, between the Highland school and Warren's tavern; 
another near Mr. Ardens, two miles south-southeast of West Point; 
another near Philips' mil!, one and a quarter miles east of West-Point; 
another at Cotton Rock, three miles south-southeast of West-Point; 
another still below, on the shore of the Hudson; two others on the 
shore, and a quarter of a mile east, near the old silver mine; another at 
the White mine on Anthony's Nose mountain; another three miles east- 
southeast of West-Point, near the Post road; another near Davenport's 
tavern, five miles northeast of Cold Spring; and another on Mr. Theo- 
dore Hustis' farm, one mile north-northeast of Davenport. All these 
localities are supposed to be in the same bed of limestone which is ex- 
posed in these various points, and probably in many others. Hustis' 
quarry is in the limestone bed above mentioned. Some parts of the hill 
are granular limestone, and a part is nearly compact magnesian lime- 
stone or miemite. Serpentine is frequently intermixed ^ forming a verd 
antique marble, which may, perhaps, at some future time be applied to 
use. Several fine minerals occur at this locality, which was discovered 
by Dr. Barratt in 1822. The precious serpentine of this locality is 
perhaps not surpassed in beauty by that of Newburyport or Easton, or 
even any locality known. It occurs crystallized distinctly with various 
modified forms. White coccolite, white augite, diopside, sahlite, phos- 
phate of lime, amianthus, asbestus, pearl spar, pyrites, chromate of iron, 
magnetic oxide of iron, and various other minerals occur at this locality. 
The bed of limestone at this place forms a bed twenty to fifty feet 
thick, resting against granite or scinite on the west, while a stream 
flows at the base of the hill. It is diflScult to determine whether it can 
be quarried with advantage, but it lies in nearly vertical strata on the
