Abstract
CONSIDERABLE attention has recently been devoted to the internal resources of Germany as a producer of various metals, more particularly, of course, of such metals as play an important part in the manufacture of war material. It has been shown that the normal consumption in Germany of copper, for example, is about 250,000 tons yearly, whilst the production is only about 25,000 tons, of which 20,000 tons are produced from one mine alone, the well-known Mansfeld mine, so that the possibility of any great increase in the domestic production would appear to he remote. The bulk of the German copper is imported from the United States, which produces more than half of the world's supply of copper, amounting now to about one million tons per annum, so that in normal times Germany purchases about one half of the United States' output of copper. It is obvious that the American producers of this metal must be seriously affected by the loss of so very important a customer.
