By John A. Church, E.M., Ph.D., of New York City. A Paper Read Before the American Institute of Mining Engineers at the New York Meeting, February, 1880. Printed for the Author. Brown soft cover. 8pp. The first edition was printed covering the May of 1878 meeting at the Chattanooga, an offprint from "Transactions of the American Institute of Mining Engineers." The findings presented at this first presentation (by permission of Lieut. George M. Wheeler, Corps of Engineers, U.S.A., in charge of U.S. Geographical and Geological Surveys west of the one hundredth meridian) came under much criticism by Mr. John Arthur Phillips who countered some of the conclusions in the Quarterly Journal August 1879. In this 8pp. paper, that Church had privately printed, he corrects and refines his conclusions concerning the sources of unbearable heat in the mines of the Comstock. Church identifies the problem as being caused by hot gasses and water. “The quantity of this steam in the up cast is greater in the Comstock than in any other mines I have ever seen.” A few small chips out of wrappers, and some separation, otherwise very good condition. OCLC records six copies. Date: Location: Virginia City, Nevada HWAC# 58505
