Sharon Springs, Schoharie County. — The Lower Helder- 

 berg limestones at Sharon Springs and its vicinity are 

 opened at several points, and stone is obtained for local use 

 in flagging, cross-walks and house work. The limestones 

 of the Upper Helderberg epoch in their westward extension 

 into Otsego county, crop out In many ledges In the towns of 

 Cherry Valley and Springfield, and afford good building stone 

 for local use. The Presbyterian church and Belcher House, 

 In the village of Cherry Valley ; the Otsego county jail, 

 Fenlmore House, and the house of Edward Clark in Coop- 

 erstown, are examples In construction of the stone from 

 these quarries. In the town of Stark, In Herkimer 

 county, a small quarry has been worked in the same gray 

 limestone. 



The cornlferous limestone was opened many years ago In 

 small quarries at Cassville, Waterville and Oriskany Falls, 

 in the southern part of Oneida county. 



Perryville, Madison County. — Three quarries are worked 

 at irregular times at this place. The stone is the Onondaga 

 gray limestone and is used as there is a demand for it ; for 

 bridge work mainly. 



In Onondaga county the Onondaga gray limestone Is well 

 developed and Is quarried extensively. There are quarries 

 at Manlius, Jamesville, on the Onondaga Indian Reservation, 

 and at Splitrock. 



Onondaga Indian Reservation Quarries. — This group of 

 quarries Is six and a half miles south of Syracuse and In the 

 north-east corner of the Reservation. There are five parties 

 at work within a range of three-eighths of a mile from north 

 to south. The dip of the beds Is generally to the west- 

 south-west, and at low angles. 



The upper beds are blue limestone which Is waste, except- 

 ing a small part which is used for rubble. The gray lime- 

 stone has a crystalline texture, and a specific gravity of 

 2.708, equivalent to a weight of 168 pounds per cubic foot. 

 It is dressed readily and fine-tooled surfaces are light gray,
