Excerpt from 22nd Annual Report of the Bureau of Mines, Mining and Mine Inspection of the State of Missouri: For the Year Ending December 31, 1908 The introduction of automatic power shovels in the mines of the Southwest district is still an' experiment. The first of these steam shovels was installed by the American Zinc, Lead and Smelting Com pany. The desire to increase the output, and the scarcity of American born mine laborers has induced the trial of the power shovel. The substitution of the steam shovel for hand shovelers will, however, depend upon its adaptability in underground work in this section, and the possibility of increasing the output.
