Washington DC: M'Gill & Witherow, 1874.
Softcover. Very Good. 96 pp, indexed. Light general wear and soiling to wrappers, small notation in ink on back cover. Contents clean, binding sound. Includes an opinion of Jeremiah S. Black, attorney for the Sutro Tunnel Comany; a report by Adolph Sutro on "The Mineral Resources of the United States and the Importance and Necessity of Inaugurating a Rational System of Mining"; a "memorial" from the Nevada Legislature asking the United States to aid in the construction of the Sutro Tunnel, and additional documents related to controversies arising from the Sutro Tunnel Act of 1866. The Act granted Sutro the right of way he needed to construct his proposed drainage tunnel, which he argued would alleviate the flooding of the mines under Virginia City, saving pumping costs, allowing for deeper mining, and providing better ventilation and an additional means of escape for miners. The Act also granted him lucrative mining rights along the length of the tunnel and was perceived as a threat by other mining interests.
