Excerpt from Transactions of the International Engineering Congress, 1915
To properly treat this subject would require a large staff of experts; their labors would fill some tens of thousands of pages. In the limited space allowed me I shall mention a few matters that seem interesting and will give some references to publications wherein the desirous student may pursue the subject further.
To make an acceptable definition is not easy: broadly speaking, "Mining" is the extraction of metals, minerals, mineral fuels, ores, and structural materials from the earth. In so far as it works in the earth, mining resembles agriculture, and the relative merits of mining and agriculture have been disputed from time immemorial. Agricola devotes several pages to this subject and has practically exhausted it; he finds "that mining is not less noble, though far more profitable than agriculture" and that it is a "calling of peculiar dignity". Agricola"s remarks are full of classical quotations and are interesting and profitable reading.
