Excerpt from The Heat of the Comstock Mines Fortunately for the purposes of this survey, Captain T. G. Taylor, superintendent of the Yellow Jacket mine, has caused observations to be taken for several months on the temperature of the air current in different parts of that mine. By noting the increase of heat and the amount of air flowing through the drifts, I have been able to obtain an approximate estimate of the amount of heat drawn from the rock surfaces. It is approximate only, because the records of surface temperatures for several months were accidentally destroyed, and I was compelled to replace them from the careful records taken by Mr. B. Gilman, of the Chollar Potosi mine, which is in Virginia, and has a higher position and a different exposure from the Yellow Jacket. The present calculations are presented merely to show that these observations contain trustworthy evidence that the heat taken up by the air cannot be derived from deep sources, by transmission through the rocks, nor from a magazine of heat lying dormant in the strata.
