This CD contains the page images and searchable text from a reference on the technology of mining in the early 1900s. In this 300-page work, mining engineer W. H. Tinney drew upon his extensive experience to develop "a manual describing the principal features of the machines employed in gold mining: their sizes, capacities, and speeds, and the rules and formulae governing their use".
