beautiful bluish gray colour. The quarries are about half a mile north 
of Fort Putnam. 
A quarry has been opened at Block-House Point, about half a mile 
below West-Point, or three-fourths of a mile below Gee's Point. 
Another quarry may be opened about one-fourth of a mile above 
Block-House Point, on the shore, northeast of the Hospital. 
Another quarry has been opened on the shore, about half way between 
Block- House Point and Mrs. Kingsley's. Much of the rock along the 
shore to near Mrs. Kingsley's landing, may be quarried with advantage. 
Cozzens' quarry is one-fourth of a mile below Mrs. Kingsley's. 
A quarry has been wrought on the shore, about one-fourth of a mile 
above Buttermilk falls. 
Another extensive one might be opened between that and Buttermilk 
falls. 
Another quarry is at Buttermilk falls. 
Mearn's quarry is half a mile below the falls. 
Two other quarries are within one mile below the falls* 
Faurot's quarries are half a mile and one mile below Consook island. 
Capt. F. has sold 1,200 tons of stone in New-York this year at $1 .75 
per ton. 
Another may be opened near Fort Montgomery. 
Many other quarries might be opened along the shore at intermediate 
points, where the stone is of good quality j but much care is necessary 
in selecting judiciously, since a large portion of the mass of gneiss rock 
is not of a good quality. Little of the rock from Faurot's quarries to 
Mearn's quarry is good. 
Several fine gneiss quarries might be opened on Waggon's islands, 
and between these and Caldwell's Landing. 
Talcose Slate. 
This rock is seen on the shore of the Hudson, about one mile and a 
half or two miles below Caldwell's Landing. It passes on the west side 
of the limestone in which Tompkin's quarries are located, and crops out 
again in the bay beyond the first quarry, and is seen on the shore west
