This folder contains correspondence and other documents relating to nickel- bearing properties. Most of the documents deal with the Sudbury district of Ontario, but some concern Oregon, Connecticut, and other locations. The correspondents include David T. Day of the U.S. Geological Survey and J. C. Ryan of the Soho Group of Mines in British Columbia. Several items relate to Edison's tour of the Sudbury district during August 1901 and his subsequent interest in nickel-bearing properties. Included are notes in Edison's hand regarding properties and sample ores; notes pertaining to the status of lease applications; and field reports by John V. Miller and Cloyd M. Chapman. Also included are an incomplete draft of Edison's agreement with the Department of Crown Lands in Ontario; a prospectus for a nickel company; and an undated report on the international nickel industry. In addition, there are documents concerning Edison's interest in magnetic surveying needles; the estimated amounts of nickel required by the Edison Storage Battery Co.; and a request from the U.S. Geological Survey for a hand-held magnetic separator.
Approximately 50 percent of the documents have been selected. The unselected items include letters of introduction; routine correspondence concerning mining properties or mineral samples; requests for maps; and prospectuses of the Nickel Copper Co. of Ontario, Ltd., and the Great Lakes Copper Co.
