THE MINING AND QUARRY INDUSTRY 1912 57 



owned respectively by the Retsof Mining Co. and the Sterling 

 Salt Co., and by the evaporating plant of the Genesee Salt Co., 

 at Piflard. The other companies now active in this section include 

 the Leroy Salt Co., of Leroy; the Rock Glen Salt Co., of Rock Glen; 

 and the Worcester Salt Co., of Silver Springs. 



In Schuyler county salt is obtained around Watkins. The Glen 

 Salt Co. sank the first well there in 1893 and encountered a deposit 

 at 1846 feet depth. The plant is now operated by the International 

 Salt Co. The Watkins Salt Co. also has works at this place. 



A well drilled at Ithaca, Tompkins county, in 1885 passed through 

 seven beds of salt aggregating 248 feet in thickness at depths below 

 2244 feet from the surface. The discovery was followed by active 

 developments at Ludlowville in 1891 by the Cayuga Lake Salt Co., 

 and at Ithaca in 1895 by the Ithaca Salt Co. The plants were 

 taken over in 1899 by the National Salt Co., which was merged in 

 1905 into the International Salt Co. The Remington Salt Co. 

 later erected a plant at Ithaca which is now in operation obtaining 

 its salt from three wells at a depth of about 2100 feet. 



The Solvay Process Co. derives its supply of brine from a num- 

 ber of wells located in the town of Tully, 20 miles south of Syra- 

 cuse. The brine is carried in pipe line to the works at Solvay. 



In Erie county rock salt has been found at Eden Valley, Spring- 

 ville, Perry and Gowanda, but there is no output at present in that 

 county. Among the localities where discoveries have been made 

 may be mentioned Vincent and Naples, Ontario county ; Dundee, 

 Yates county; Seneca Falls, Seneca county; and Aurora, Cayuga 

 county. None of these deposits are worked. A well put down in 

 1909 in the town of Burns, Allegany county, is reported to have 

 passed through 75 feet of clean unbroken salt at 3050 feet depth. 



SAND AND GRAVEL 

 The production of sand and gravel for use in engineering and 

 building operations, metallurgy, glass manufacture, etc., is an im- 

 portant industry involving a very large number of individual opera- 

 tions. The building stone business is specially extensive as there 

 are deposits suitable for that purpose in every section of the State, 

 and nearly every town or community has its local source of supply. 

 Such sand, of course, possesses little intrinsic value. The deposits 

 of glass sands and molding sands are more restricted in their dis- 

 tribution and their exploitation is the basis of a fairly stable indus- 

 try; certain molding sands are even shipped to distant points, as 

 in the case of those obtained in the Hudson River region.
