Smith, Jacob Green and Jonas Conklin. It is not known how many- 
sets of stones are obtained at these quarries, but the probable receipts are 
from $4,000 to $10,000 per annum. 
Red Sandstone or Freestone. 
This rock is extensively worked for cutstone, for flagging stone, and 
rough stone for basements along the shore of Tappan bay. The shore 
is skirted by quarries from two miles below Nyack to two miles above 
that place. Some of these quarries have been worked for more than fifty 
years. 
Gesner's quarry is at the ship yard, about half a mile below Nyack. It 
is not much worked. 
Westervelt's quarry is one mile north of Nyack. It was visited by 
Mr. Cassels. The flagging stone 1^ feet wide, and 2 to 3 inches thick, 
are delivered in New- York at 15 cents per foot. Rubble stone of 
this sandstone sells in New-York for 62 i cents per cart load of 15 cwt. 
The transport costs about one-fifth of this amount. The proprietors re- 
ceive one-fifth of the proceeds of sales for rent from those who w^ork the 
quarries. 2,000 feet of slabs besides rubble have been quarried this 
year. Clark's quarry is one and a half miles north of Nyack. Speci- 
mens of the sandstone of this and several other quarries are in the State 
collection. 
Wilkin's quarry is one mile south of Nyack. 5,000 to 6,000 feet of 
slabs have been quarried here this year, and 500 cart loads of rubble stone. 
The two quarries of Daniel Onderdonk and his brother are near each 
other below Nyack. 2,500 feet of slabs or flags have been quarried the 
past season from each. 
Richard Clark's quarry is near Onderdonk's. 
There are sixteen quarries in operation below, and fifteen above 
Nyack, within two miles from that place, which will average about 2,000 
feet of slabs, (as Mr. Cassels was informed,) and 500 loads of rubble 
stones each, per annum. 
This would give the product of the 31 quarries the last year as 62,000 
feet of slabs, valued at $9,300 00 
and 15,500 cart loads of rubble, at 9,687 50 
$18,987 50
