DESCRIPTION OF SANDSTONE QUAKEIE8 395 



of the older stone buildings in Albany have their walls of these 

 natural face blocks. 



Schenectady. — Albert Shear & Co. have a quarry on the canal, 

 one mile east of the railroad depot, which is the source of supply 

 to a large extent, for stone used in the city, although shipments 

 are made to Albany, "Waterford, Cohoes, Troy, Mechanicville 

 and Saratoga. 



This stone can be seen in the Memorial Hall of Union 

 University and in the East Avenue Presbyterian Church ; in 

 the new armory, Albany ; in the church at Menands Station, 

 and in St. Patrick's Roman Catholic Church in West Troy. The 

 stone has a bluish shade of color and is fine-grained. 



Duanesburg, Schenectady County. — A quarry in a bluish- 

 colored sandstone, probably of the same geological horizon as 

 that of the Schenectady quarry, is here worked by Albert Shear 

 & Co. The stone is rather coarse-grained but is stronger than 

 the Schenectady bluestone. 



The shaly nature of much of the Hudson river group of rocks 

 in the Mohawk valley, west of Schenectady, and the accessibility 

 of good limestone for building purposes, has prevented the open- 

 ing of quarries in it. Further west, and near Rome, there are 

 small quarries which are referred to this horizon, but they are 

 unimportant. The stone is generally gray in color, fine-grained 

 and hard, and in moderately thick beds. None of these quarries 

 do much more than a small local business ; and they are not in 

 operation all of the working season of the year. 



Good building stone of the Hudson river horizon is said to 

 have been obtained at quarries southeast of Rome ; also at 

 Woodruffs, Oneida County*. 



Clinton Group. 



This formation furnishes a building stone in Herkimer and 

 Oneida counties, and quarries are opened in the towns of Frank, 

 fort, JSTew Hartford, Kirkland and Verona. The city of Utica 

 uses the greater part of the stone from the quarries at Clinton
