As is generally the case in real dilemmas, the French and Italian case will possess great force, indeed unanswerable force from a certain point of view. The position will be truly represented as a question between German industry on the one hand and French and Italian industry on the other. It may be admitted that the surrender of the coal will destroy German industry, but it may be equally true that its non-surrender will jeopardize French and Italian industry. In such a case must not the victors with their Treaty rights prevail, especially when much of the damage has been ultimately due to the wicked acts of those who are now defeated? Yet if these feelings and these rights are allowed to prevail beyond what wisdom would recommend, the reactions on the social and economic life of Central Europe will be far too strong to be confined within their original limits. But this is not yet the whole problem. If France and Italy are to make good their own deficiencies in coal from the output of Germany, then Northern Europe, Switzerland, and Austria, which previously drew their coal in large part from Germany's exportable surplus, must be starved of their supplies. Before the war 13,600,000 tons of Germany's coal exports went to Austria-Hungary. Inasmuch as nearly all the coalfields of the former Empire lie outside what is now German-Austria, the industrial ruin of this latter state, if she cannot obtain coal from Germany, will be complete. The case of Germany's neutral neighbors, who were formerly supplied in part from Great Britain but in large part from Germany, will be hardly less serious. They will go to great lengths in the direction of making their own supplies to Germany of materials which are essential to her, conditional on these being paid for in coal. Indeed they are already doing so.[49] With the breakdown of money economy the practice of international barter is becoming prevalent. Nowadays money in Central and South-Eastern Europe is seldom a true measure of value in exchange, and will not necessarily buy anything, with the consequence that one country, possessing a commodity essential to the needs of another, sells it not for cash but only against a reciprocal engagement on the part of the latter country to furnish in return some article not less necessary to the former. This is an extraordinary complication as compared with the former almost perfect simplicity of international trade. But in the no less extraordinary conditions of to-day's industry it is not without advantages as a means of stimulating production. The butter-shifts of the Ruhr[50] show how far modern Europe has retrograded in the direction of barter, and afford a picturesque illustration of the low economic organization to which the breakdown of currency and free exchange between individuals and nations is quickly leading us. But they may produce the coal where other devices would fail.[51]
