54 Report on Building Stone^of New York. 



sandstone is fine-grained, of a bluish shade of color* and is in thick 

 beds. Some beds of slaty rock occur with the standstone. The 

 stone splits readily along planes in bedding and where there are thin 

 laminae of calcite and quartz, known as "hair seams " and " salt seams." 

 There is a dock on front at which boats are loaded. The quarry fur- 

 nished stone for foundation of the Reformed church at Castleton. 

 Formerly a great market was at Albany. It has been opened 23 

 years. To the south a few rods there is an abandoned quarry also 

 owned by Matthews. 



James Bronk's quarry, worked by Fuller & Sons, adjoins the 

 abandoned Matthews' quarry. A large area at the north is no longer 

 worked. The present quarrying operations are confined to a length 

 of 200 feet. The strata here dip toward the north-east and at an 

 average inclination of 30°. The beds are thick. One near the top 

 measures 10 feet. And there is relatively less of the shaly or slaty 

 rock here than in the other quarries of this group. There is a dock 

 on the river where boats are loaded. 



The New Baltimore quarries have no machinery for hoisting or 

 drilling. Common black powder is in use for blasting. The stone 

 are carted to the boats. And the whole product is sold for common 

 walls or for dykes. The prices range from 30 cents per cubic yard 

 on the dock to 75 cents and one dollar per yard, delivered on dykes 

 in river, or for better grade of building stone. 



Troy, Rensselaer County. — Sandstone of the Hudson river 

 group is quarried in this city for foundation work exclusively, and 

 for the home market. Sampson's quarry on Pawling avenue, near 

 the Memorial church, leased by William McLaughlin, is worked by 

 a small force of men a part of the year. 



Havernan's quarry on Fourth street, south of the Poestenkill, is 

 run by the owner, and from eight to twenty men are employed. The 

 sandstone is interbedded with slaty rock in these quarries, and there 

 is some waste in the working. The stone is not adapted to fine 

 dressing or cut work. 



At Aqueduct, Schenectady County, there are three quarries. 

 The largest one of these quarries is that of Levi Smith, on the south 

 bank of the Erie canal and a half a mile west of Aqueduct station. 

 It has a length from north-east to south-west of 800 feet. Tne order 

 of succession of the strata from the surface is :
