DESCRIPTIVE NOTES OF QUARRY DISTRICTS AND QUARRIES 249 



Malone, Waddlngton and Canton ; the Roman Catholic 

 church at Hogansburg, and In the county buildings at 

 Canton. 



Schoharie, Schoharie County. — Limestones of the Lower 

 Helderberg and Water-lime groups crop out in the valley 

 east of the village of Schoharie, and afford excellent build- 

 ing Stone. The black, tentaculite limestone is very compact 

 and takes a high polish. The use thus far is for the town 

 only. 



The Reformed Dutch church and Revolutionary stone 

 fort in the lower Schoharie valley, built in i 766, shows how 

 well the limestone resists the weather. 



Howe's Cave, Schoharie County. — Formerly a large 

 amount of building stone was quarried here in the bluff, 

 above the hydraulic limestone beds. The latter only are 

 now worked. 



Cobleskill, Schoharie County. — William Rellly has two 

 quarries near this place ; one a half mile north-west of the 

 village, and the other about two miles to the north-east. 

 Both are In the Upper Helderberg limestone. 



Two principal kinds of stone are taken out, — a hard blue- 

 stone, and a gray, sub-crystalline variety, which is cut and 

 dressed for dimension work. A specimen of the latter was 

 examined and found to contain 53.86 per cent of lime, or 

 96. 18 per cent of carbonate of lime, and 2.26 per cent of 

 matter insoluble in dilute hydrochloric acid. Its specific 

 gravity was 2.713, equivalent to a weight of 169 pounds to 

 the cubic foot. The absorption percentage was 0.109. Un- 

 affected apparently by alternate freezing and thawing, it was 

 calcined at a high heat (1200°- 1400° F.). 



The stone of this quarry has a home market; It Is shipped 

 to Binghamton, Oneonta, Cooperstown, Albany and other 

 places on the Albany and Susquehanna railroad. It was 

 used in the German Methodist Episcopal church, Clinton 

 and Alexander streets; in the Roman Catholic church, Cen- 

 tral avenue, and in the Hawk street viaduct, Albany.
