This collection consists primarily of letters from the secretary to the president of the North Bloomfield Gravel Mining Company
of Nevada County, California, in
1890-1891 related to the company and hydraulic mining.
The North Bloomfield Gravel Mining Company was a company that pioneered in the development of
hydraulic mining for gold in Nevada County, California, during the 1870s. Subsequent
restrictions on hydraulic mining operations forced the company to adopt new procedures to
protect downstream agriculturalists from the effects of water-borne mining debris.
