The progress of knowledge naturally leads to the discovery not only of new arts, and of new uses for artificial productions, but of new stores of natural wealth in the bowels of the earth itself, and of new methods of extracting and rendering them useful. This last point is amply illustrated by the history of the progressive discovery and development of our own most valuable mineral treasures—the coal and ironstone deposits—which add so much both to our natural resources and to our national strength.
