THE MINING AND QUARRY INDUSTRY IQI2 57 
owned respectively by the Retsof Mining Co. and the Sterling 
Salt Co., and by the evaporating plant of the Genesee Salt Co., 
at Piffard. 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 
Ig09 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 1m- 
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.
