106 Report on Building Stone of New York. 



on which stone is carted to the canal or railroad. The stone is sold 

 for rough wall work, and is cut for house trimmings. 



Mrs. Moore's quarry adjoins that of Walker on the east, and with 

 it makes really one continuous opening. The excavation has gone 

 over an area of 100 yards by 50 yards, and the face of the quarry 

 runs a south 20° east course. It is 10 to 15 feet deep. The dip is 

 3° south-south-east. One system of joints runs south 45° east and a 

 second one, north 20° east, vertically. Here also the top strata are thin, 

 and the thick beds are at the bottom. This quarry has not been in 

 operation for several years past. 



Both of these quarries are in the Trenton limestone. 



Amsterdam, Montgomery County. — The building stone quarries 

 at this place are one mile from the N. Y. C. railroad station and near * 

 the Chuctanunda creek, aid from 180 to 250 feet above the Mo- 

 hawk. The quarry beds crop out in the sides of the creek valley. 

 Ascending northward, the first quarry is that of James Shanahan, 

 which is on the eastern side of the creek, and about 200 yards north 

 of the paper mill. The working face is 200 feet long from east to 

 west, and has in it a thickness of 8 to 12 feet of quarry beds, above 

 which there is drift earth up to 10 feet thick. The beds are from 1 

 to 3 feet thick, and they dip very slightly to the west. The stone is 

 blue and sub-crystalline. The quarry has one derrick and there is 

 natural drainage. On the west side of the stream, Thos. J. Donlon 

 quarries limestone on the Vanderveer farm. This place was opened 

 first nine years ago. The working face has a length of 500 feet, par- 

 allel nearly to the creek, and is 15 to 20 feet iu height. The joints 

 run, vertically, north and south and east and west. The beds are from 

 2 inches up to 2 feet thick ; and the bedding surfaces are rather 

 rough and uneven. The stone is a blue limestone, of Trenton epoch. 

 The product goes mainly for common masonry, as foundation walls. 

 Another quarry has been opened north of Vanderveer's for limestone 

 to be used in lime making. 



The quarry of D. C. & N. Hewitt is on the left side of the Chucta- 

 nunda creek and east of the Rock City road. At the south opening, 

 which was made many years ago, the rock is a dense, blue limestone, 

 like that of Shanahan's quarry. It is the largest and deepest exca- 

 vation here. The new quarries are about 20 rods northward and on 

 the same side of the road. At this place a large area has been worked 

 over, since two beds only are raised.
