	The Onondaga Salt Springs Reservation was a tract of land designated by the state legislature in 1797 around a natural salt spring for the commercialization of salt production in Salina on the shores of Onondaga Lake. Production began around 1789; salt was made by boiling the brine of the water. In 1798, Sanger, Asa Danforth, and about a half-dozen other investors formed the "Federal Company", which increased production by building the first permanent building at the site for salt manufacture, building a new and bigger well, and starting a large-scale operation of 32 kettles for producing salt. This company was the largest producer at the time. Sanger sold his interest in the company after two years.
