DESCRIPTIVE NOTES OF QUARRY DISTRICTS AND QUARRIES 26 1 



lected stone and set on edge In many cases. A great deal 

 of It has been used In Fulton, Oswego and Syracuse. 



A specimen from the quarry of Hughes Brothers of Syra- 

 cuse was found to have a specific gravity of 2.62, and an 

 equivalent weight of 163.5 pounds to the cubic foot. It 

 contained 0.59 per cent of ferrous oxide, and 1.71 per cent 

 of ferric oxide. The absorption test gave as a result 3.53 

 per cent. It lost weight In the treatment with acid solu- 

 tions. In the freezing and thawing It checked badly, and 

 at a high heat Its color became brick-red, and Its strength 

 was Impaired. 



Granby, Oswego County. — The Granby Brownstone Com- 

 pany, O. J. Jennings, manager, works the quarry on the 

 line of the Delaware, Lackawanna and Western railroad, 

 two miles south of Fulton. The stone Is fine-grained, pur- 

 plish-red In color, and admits of fine-tool dressing. It has 

 been used In the following structures In neighboring towns 

 and cities : Second National Bank building, Oswego ; Pro- 

 testant Episcopal church, and a block of stores In Cortland; 

 and new Jewish synagogue, Buffalo. 



Small quarries are opened westward In this formation at 

 Camden, Oneida County 

 Sterling, Cayuga County 

 Wolcott, Wayne County 

 Penfield, Monroe County 



At Rochester the gorge of the Genesee river exposes to 

 view a fine section of the formation. Formerly some stone 

 was obtained from quarries in the river bluffs. In Monroe 

 county generally this sandstone is too argillaceous to be 

 durable.* 



What is more particularly known as the Medina sand- 

 stone district, is that portion of the outcrop which extends 

 from Brockport in Monroe county west to Lockport. The 

 belt is narrow, and the quarries are opened in it near the 

 Erie canal. They are grouped here as follows :
