Collection consists of an original manuscript, "Geology and Ore-Deposition at Tonopah, Nevada" by Josiah Edward Spurr (1870-1950) with hand-drawn diagrams, and letters discussing the donation of the manuscript. The manuscript, which was published in the journal Economic Geology in 1915, is a geological description of the Tonopah mining area; the Tonopah Mining Company is mentioned frequently. It is undated, but the publication date suggests it was written approximately 1913-1915.
