Little Falls, Herkimer County. — A hornblendic-gneiss 

 rock, known as *' blue rock," is quarried at Little Falls for 

 the local market. It was used in the construction of the 

 Erie canal, the N. Y. C. & H. R. R. R., in the R. C. and the 

 Pres. churches, besides several mill and store buildings in 

 the town. The stone has a greenish-gray color, moderately 

 fine-crystalline texture, and is made up of orthoclase, 

 quartz and hornblende. Some of it has a reddish tinge, due 

 to iron stains. 



Granite has been quarried In the town of Wilton, two 

 miles north of Saratoga, in the town of Greenfield, and at 

 Wolf Creek, in the town of Hadley. None of these quar- 

 ries are worked regularly or uninterruptedly. 



Adirondack Granite Company, Westport, Essex County. — 

 The granite quarry has been abandoned, on Splitrock moun- 

 tain near the lake, and three miles from Whallonsburg. 

 Very little stone has been quarried here and little is known 

 of it. 



Ausable Granite, Essex County — The Ausable granite is 

 obtained from quarries on the north and west slopes of 

 Prospect Hill, one and a half miles south of Keeseville. 

 The principal openings are the property of the Ausable 

 Granite Works, whose establishment for dressing the stone 

 is located in Keeseville. This stone is moderately fine- 

 crystalline in texture and is composed of feldspar, hypers- 

 thene and biotite. Small grains of pyrite and hematite are 

 occasionally seen in the mass. The stone is hard and ex- 

 pensive to dress but it is susceptible of a high polish and is 

 especially adapted for decorative work and for monuments. 

 The dark, polished surface, with its chatoyant play of colors, 

 contrasts well with the gray, dressed surfaces. The glaci- 

 ated ledges near the quarries show little alteration due 

 to weathering, and are evidence of the durability of the 

 stone. In some of the weathered surfaces the feldspars
