The sites selected for the hospitals were either French hospitals which were given over, or schools or big public buildings remade into hospitals by the engineers. Each site was arranged so that it could be enlarged at will. And the railways which connected the outlying hospitals with the rest of the American communications were laid so that other hospitals could be easily placed along their line. There was a splendid elasticity in the Medical Corps plan. One base hospital was much like another, except for size. Those near the line differed somewhat from those farther back, but their scheme was uniform. At any rate, the history of their doings was similar enough to have one history do for them all. Take, for example, one of the New York units which landed in August and was placed nearer the coast than the fighting. It was put in trim by the engineers, then sanitated by the humbler members of the Medical Corps. The great wards were laid out, the kitchens were built, windows were pried open--always the first American job in France, to the great disgust and alarm of the French--and baths were put in. The chief surgeon had specialized in noses and throats at home. When the hospital was ready, naturally the soldiers were not in need of it--being still in training in the Vosges--so the services of the hospital were opened to the civilian population of France. By November there was not an adenoid in all those parts. The death-rate almost vanished. Into this rural France, where there had been no hospital and only a nursing home kept by some Sisters of Mercy who saw their first surgical operation within the base hospital, there came this skilful organization, handled by men whose incomes at home had been measured in five figures, and all the healing they had was free. Multiply this by twenty, and then by thirty, before the pressing need for care for soldiers directed the Medical Corps back to first channels, and there will be some gauge of what this service did for France. And the gratitude of France was more than commensurate. Praise of the American Medical Service flowed unceasingly from officials and civilians, statesmen and journalists. There were constant demands made upon the French Government that it should pattern its own medical forces exactly upon the American, making it the branch of the medical specialist and not of the politician or the military man. The individual officers of the Medical Corps had much to learn, however, from the French and the British. Though they knew hygiene, prophylaxis, antisepsis, and surgery as few groups of men have ever known it, they became scholars of the humblest in the surgery of the battle-field. Every officer of the Medical Corps was kept on a round of visits behind French and British fronts during the fairly peaceful interim between their landing and the American occupation of a front-line sector.
