Usually pocketed in the mountains, the mine, the furnace, and the forge have remained a little off the track of civilization: isolation and monotony add to the defects of the activities themselves. In an old industrial domain, like the Rhine Valley, dedicated to industry since the days of the Romans and refined by the technical and civil advances of the whole community, the direct effect of the miner’s culture may he greatly ameliorated: this is true in the Essen district today, thanks to the original leadership of a Krupp and the later planning of a Schmidt. But taking mining regions as a whole, they are the very image of backwardness, isolation, raw animosities and lethal struggles. From the Rand to the Klondike, from the coal mines of South Wales to those of West Virginia, from the modern iron mines of Minnesota to the ancient silver mines of Greece, barbarism colors the entire picture.
