...several feet out of line. (Mines and Minerals, March, 1902, p. 342.) It seems to be generally admitted that in the crushing of a rigid material, such as rock, almost the entire mechanical work is transformed into heat; and hence if "the disturbance affecting the massive strata of a great mountain... | |

With all the harder rocks the heat produced in the metal surroundings by the complete crushing was easily perceptible by the hand, and was so great with some of the granites and porphyries as to necessitate a delay for the apparatus to cool. Both Mr....
