But even when coal can be got and grain harvested, the breakdown of the European railway system prevents their carriage; and even when goods can be manufactured, the breakdown of the European currency system prevents their sale. I have already described the losses, by war and under the Armistice surrenders, to the transport system of Germany. But even so, Germany's position, taking account of her power of replacement by manufacture, is probably not so serious as that of some of her neighbors. In Russia (about which, however, we have very little exact or accurate information) the condition of the rolling-stock is believed to be altogether desperate, and one of the most fundamental factors in her existing economic disorder. And in Poland, Roumania, and Hungary the position is not much better. Yet modern industrial life essentially depends on efficient transport facilities, and the population which secured its livelihood by these means cannot continue to live without them. The breakdown of currency, and the distrust in its purchasing value, is an aggravation of these evils which must be discussed in a little more detail in connection with foreign trade.
What then is our picture of Europe? A country population able to support life on the fruits of its own agricultural production but without the accustomed surplus for the towns, and also (as a result of the lack of imported materials and so of variety and amount in the saleable manufactures of the towns) without the usual incentives to market food in return for other wares; an industrial population unable to keep its strength for lack of food, unable to earn a livelihood for lack of materials, and so unable to make good by imports from abroad the failure of productivity at home. Yet, according to Mr. Hoover, "a rough estimate would indicate that the population of Europe is at least 100,000,000 greater than can be supported without imports, and must live by the production and distribution of exports."
The problem of the re-inauguration of the perpetual circle of production and exchange in foreign trade leads me to a necessary digression on the currency situation of Europe.
