The Ore Finders

Man has always felt more comfortable breaking his life into categories or classifications. An otherwise bewildering life somehow becomes easier to bear when divided into neat measurable sections, each of which is fitted into its proper niche. It seems likely that the world's first economic geologist, when faced with the world's first two ore bodies, started his career by classifying them. Early on, he divided his ore bodies into those born of water, of fire, and of air. In retrospect this threefold classification was probably about as useful as the more complex ones that followed. This division of ore bodies probably did not help him in his search for new deposits, but it made him feel more secure in dealing with those already known.
