Three factors are of chief importance in estimating German man-power. First, the number of men of military age; second, the number of these that are indispensable in civil life; third, the number of casualties. Concerning the last two there are great differences of opinion among military critics in Allied and neutral countries. As regards the first there need be little difference, although I confess surprise at the number of people I have met who believe the grotesque myth that Germany has systematically concealed her increase in population, and that instead of being a nation of less than seventy millions she has really more than one hundred millions. It is safe to say that at the outbreak of war Germany was a nation of 68,000,000, of whom 33,500,000 were males. Of these nearly 14,000,000 were between 18 and 45; 350,000 men over 45 are also with the Colours. The boys who were then 16 and 17 can now be added, giving us a grand total of some 15,000,000. Normally Germany employed men of between 18 and 45 as follows:--Mines, 600,000; metals, 800,000; transport, 650,000; agriculture, 3,000,000; clothing, food preparation, 1,000,000, making a total of 6,050,000. Up to this point there can be little difference of opinion. From this point on, however, I must, like others who deal with the subject, make estimates upon data obtained. During my last visit to Germany I systematically employed a rough check on the figures derived through the usual channels. Concentrated effort to obtain first-hand information in city, village, and countryside, north, east, south, and west, with eyes and ears open, and vocal organs constantly used for purposes of interrogation, naturally yielded considerable data when carried over a period of ten months. The changes from my last visit and from peace time were also duly observed as were the differences between Germany and the other nations I had visited during the war. Walking, of which I did a colossal amount, was most instructive, because it afforded me an opportunity to study conditions in the villages. Discreet questioning gave me accurate statistics in hundreds of these that I visited, and of many more hundreds that I asked about from people whom I met on my travels. For example, in Oberammergau, which had at the beginning of the war 1,900 inhabitants, about 350 had been called to the Colours when I was there, and of these thirty-nine had been killed.
