Sacramento: A.J. Johnston, 1896.
First Edition. Hardcover. Fine. No. 9 of the California State Mining Bureau. 210 pp, indexed, extensively and attractively illustrated with engravings, line drawings, and plans, including two folding plates. A fine copy in original cloth. Despite the author's claim to offer only "a short, popular exposition of methods, constructions, and principles involved in the machines used in the extremely varied conditions of mining on the Pacific Coast," he actually provides considerable detail on the design and operation of a variety of mining equipment.
