"The alien population for France is also large, considerable numbers of Italians, Spaniards, and Portuguese being employed in the southeastern region. A newer element was provided by natives from French colonies, namely, Morocco and Algeria. Since the war started large numbers of Greeks and Armenians had been imported into France; and during the last two years something like 200,000 Chinamen had been brought to France for unskilled work. The last resource was the enemy itself. There were in France more than 250,000 German prisoners engaged in various work and receiving a salary for it." Germany's industrial mobilization was picturesquely described by the head of the General Electric Co., Dr. Walter Rathenau, who was appointed at the beginning of the war to superintend the supplying of the German War Office with raw materials. He told the officials at the War Office that Germany was provided with more war materials only for a limited number of months. Accurate statistics were prepared in a short time on the power of production in various German industries. Then all the raw material was put where it could be commandeered. The flow of products was restricted, so that the raw material and also half manufactured products could be automatically diverted to articles needed by the Army. New methods were discovered and developed. Where former technical means were insufficient substitutes had to be found. Where it was prescribed that this or that article was to be made out of copper or aluminum, it was permitted to make it out of something else. All the laboring power of the country, including men from 16 to 60, were enrolled and controlled from the central organization called the War Office, described by General Gröner as follows: "The new War Office represents Germany as a colossal firm which includes all production of every kind and is indifferent to the kind of coat, civil or military, which its employes wear. The new measures are intended to mobilize all effective labor, whereas up to the present we have only mobilized the army and industry. The whole war is becoming more and more a question of labor, and in order to give the army a firm basis for its operations the domestic army must also be mobilized. All the labor, women's as well as men's, must be extracted from the population, so far as possible voluntarily. But if voluntary enlistment does not suffice we shall not be able to avoid the introduction of compulsion." THE GERMAN NATION IN ARMS
