The casualties resulting in death, permanent injury, or incapacity in the German Army have amounted to admittedly about 3,000,000 men during the four years of war, or approximately the same number as have been supplied by the young men who have reached military age during the same period. From this statement it would appear that from the point of man power Germany is no worse off today than when she started the war. The weakening of the German forces is represented, however, by the lack of nourishment for her workers, her women and children, and the discharges which must necessarily follow the reaching of advanced age by the old men called to the colors, both of which will be felt more keenly as time goes on, as well as the disease which must necessarily accompany conditions such as the war has produced. America will not begin to discharge her men on account of advanced age for twenty years. In other words, the man power of America will get stronger and the man power of the enemy must get weaker for the next twenty years, if, by any chance, the war should last that long. We have nothing to fear from this source. DIFFICULTIES ENCOUNTERED The first war difficulty encountered came when we looked for shelter for the vast army being assembled. Much to the surprise of every one, it was soon discovered that there was not cloth enough in the world to put tents over an army the size of the one we were organizing, and there were not mills and machinery enough to make it. Therefore wooden cantonments were constructed. We built thirty-two cantonments with a floor space of 640,000,000 square feet, with the necessary water, sewers, lighting plants, storehouses, ice plants, hospitals, and recreation centres to take care of 1,280,000 men, in which undertaking there was used in ten weeks' time more human labor than went into the building of the Panama Canal. Besides these, we have constructed aviation fields, ordnance schools, and training schools for officers--herculean tasks in themselves. We have also put up at the ports of embarkation, and throughout the country, supply depots, and storage warehouses with a combined floor space of 24,220,000 square feet for the army, in addition to what the navy has done in that respect, and have constructed the enormous buildings erected for administrative purposes in Washington and elsewhere. Verily, your Uncle Samuel is a modern Aladdin, who, when he wants a thing devoutly, rubs the lamp of American patriotism and the genius of America produces overnight all that he requires.
