The quarries of Mr O. A. Snooks and Mr C. Snooks together 

 occupy about 3 acres. The beds are about the same as those on. 

 the adjoining hill. The rock is of a little poorer quality, and they 

 are troubled with water in the quarries. The product is used 

 by local mills entirely. 



The gypsum quarries of the Cayuga land plaster co. 

 These quarries are described in bulletin 11 of the New York 

 state museum, p. 72. 



The bed was first opened in 1828, and the original deposit 

 covers an area of about a square mile on the east shore of 

 Cayuga lake, a mile north of the village of Union Springs, and 

 4 miles south of Cayuga. The output averages about 10,000 

 tons of plaster annually and 5000 tons of rock gypsum. The 

 entire product is disposed of by Mr Charles E. Lee of Bingham- 

 ton N. Y. The price per ton of the rock is ^1.50; of the plaster, 

 |2.50. The plaster is all of one quality, the poorer specimens of 

 gypsum rock being turned out on the dumps. Only the pure 

 gypsum is used. 



The analysis of this plaster is as follows: 



Sulfate of lime 80.78 



Carbonate of lime 1.76 



" magnesium 3 



Phosphate of lime .43 



Sand 3.32 



Organic matter .18 



Chlorin, potash and clay 10.5 



Total 100 



This analysis was made by J. A. Barral, perpetual secretary 



of the Central society of agriculture of France. 



About 2 miles north of the quarry which is worked another 



quarry is found, and at the south about half a mile distant two 



more. Xone of these are worked at present.

 Near the station a small quarry is worked by Mr Walker. The 



product is used entirely in the immediate locality. The annual 



output does not exceed 500 tons.
