THE MINING AND QUARRY INDUSTRY I9I3 



contributed by approximately thirty mines and works distributed 

 over the counties of Livingston, Onondaga, Schuyler, Wyoming, 

 Tompkins and Genesee in the relative order given of their output. 

 Of the plants, all but two were engaged in brine salt operations.

Occurre'nce of salt. The productive sources of salt are natural 

 brines and beds of rock salt. Natural brines have been found in a 

 number of places and in various rock formations, but the only occur- 

 rence that has had any great commercial importance is in the vicinity 

 of Syracuse on the old Onondaga Salt Springs Reservation, which 

 was sold to the State by the Indians in 1788. The brines are en- 

 countered in loose gravels, sands and clays which extend to depths 

 of several hundred feet and apparently lie in a channel or basin hol- 

 lowed out of the Salina rocks. The original wells were shallow, 

 but it was later found that the strength of the brine could be" in- 

 creased by going deeper and wells were put down to depths of from 

 200 to 400 feet from which the present supplies are obtained. The 

 borings of the underlying strata in the basin show that they contain
