No. 276. j 83 
The stone is now hauled to the landing, about one-fourth of a 
mile, at an expense of 3 cents per cubic foot, or 42 cents per ton. 
Much of it is sent to Sing-Sing for the culverts and aqueduct bridges; 
and the freight to that place is 4 cents per foot, or 56 cents per ton. It 
is delivered at Sing-Sing in blocks of ten cubic feet and over, at 35 cents 
per cubic foot, or |5 . 90 per ton. 
The dressing of this stone for the arches, is done at 14^ cents per su- 
perficial foot, and about two and a half superficial feet are dressed to the 
cubic foot, which make the stone dressed, ready for the arches, cost 70 
cents per cubic foot, or $9.97i per ton. 
This quarry is capable of being worked at least 70 yards in depth, 
over an area of several acres; and allowing a profit of $1 per cubic yard, 
which is a low estimate, and 4,840 square yards to the acre, 50 yards in 
depth, ought in the course of working, to give a profit of $242,000 to 
the acre. 
Siomj Pointy 1 mile J^W of Cold Springs^ Putnam county. — This 
is a rocky peninsula, stretching into the Hudson, about one-fourth of a 
mile. It is composed of gneissoid rocks, except the NW point of the 
peninsula, w^hich is a granitic rock of the same character as that of 
Blunt's and the Highland Company's quarries. About two acres of this 
peninsula are covered by this rock, to an estimated mean depth of forty- 
five feet above high water mark, and it may be estimated that there are 
145,200 cubic yards of granite capable of exploration on this point. 
It may apparently be split out in masses of any size, up to 100 tons or 
more, in regular blocks, and it lies immediately on the Hudson river, 
and with such a depth of water that large vessels may come immediate- 
ly along side of the rocks to be quarried, so that the blocks may be 
swung on board with a crane. 
Stony Point is owmed by Mr. Philips of Philipstown, who was not 
aware of the existence of such a location for a granite quarry, until he 
was informed of it during the progress of the survey of Putnam county, 
during last summer. 
Philips' Quarry. 
This belongs to the same gentleman as the preceding. It is located 
on the Philips estate, about half a mile from the Hudson river, and one 
and a half miles ENE of West-Point. The rock is perfectly inde- 
structible, and would be called granite by those who should see the 
blocks, without seeing the quarry. It is gneiss, in thick layers or plates,
