The first of the forestry regiments, the 10th Engineers, sailed for Europe five months after the declaration of war, followed at short intervals by several similar organizations. Immediately upon their arrival in France lumbering operations were begun in the Vosges and the Pyrenees (so do not be surprised if the next time you go shooting in Maine or fishing in Michigan your guide interlards his conversation with French or Spanish phrases), using French mills at first but later installing plants of the American type. The enlisted men of the forestry outfits were, as I have said, for the most part lumbermen by trade, officered by men familiar with lumbering in all its details. The result was a striking illustration of what American energy and American methods can do, for the official reports show that mills which, under French management, were yielding 500 board feet a day, were made to yield ten times that quantity when operated by Yankee lumbermen. In the Vosges this work was carried on so close to the front that the plants were repeatedly bombed by enemy aircraft and shelled by enemy artillery, the forestry troops, though listed as non-combatants, frequently suffering heavy casualties. It took a high order of courage for these men to go unconcernedly about their business of tree-felling, hauling, and sawing with German shells yowling through the branches and bursting all about them. The sawmills were of the portable type, however, and when the fire of the German guns became too accurate and heavy, the whole plant was packed up and shifted to a new location. I don’t believe in letting loose upon my defenseless readers swarms of figures, but it will serve to give those of them who are familiar with lumbering some idea of what our forestry regiments accomplished when I mention that during the month of October, 1918, alone, they produced 50,000,000 board feet of sawed lumber, 80,000 cords of firewood, and enough standard-gauge ties to build a single-track railway from the Great Lakes to the Gulf. In raising the quarry, highway, and inland waterway regiments, the same method was adopted as in the organization of the forestry battalions. Enormous quantities of crushed rock were required for concrete and for the construction and repair of roads, but though numerous quarries were available in the American areas, experienced quarrymen and quarrying equipment were lacking. Accordingly a special quarry regiment, the 28th Engineers, was organized in the United States in November, 1917, with a strength of 60 officers and some 1,500 men. A skeleton organization was formed by transferring a few officers and a small detachment of men from a road regiment, the new unit being raised to strength by giving commissions to quarry managers and superintendents and filling up the ranks with drafted quarrymen.
