Educational work of such varied sort was constantly carried on as part of the program of the Training Camp Committee as to give to much of the leisure time of every camp almost an academic atmosphere. The machinery of the university extension work and of the educational department of the Y. M. C. A. was utilized to provide for those wishing to take them a wide variety of college and commercial school courses. English was taught to those of little education and to those of foreign birth. Every camp had its classes in French. There was instruction in subjects which would prepare men to transfer from one branch of the service to another. And always and everywhere there were schools or classes or courses of study for intensive training in one or another phase of military affairs--training for those who would have to undertake these specific and varied duties, training for those who would instruct others in them, training for officers. Every camp and cantonment buzzed with these activities by which the men of a nation unused to military affairs and hating war zealously trained themselves for battle and schooled themselves in new methods of warfare. The Commission on Training Camp Activities went vigorously into the work of education in social hygiene and the enforcement of law in order to make and keep the camp environment, the camps and the men themselves morally wholesome, to the end that the army should be of the best fighting material and that the men who composed it should return to their homes as fine and clean as when they left. A determined and unceasing effort was made to keep alcohol and the prostitute away from the cantonments. Wide zones in which the sale or gift of alcohol to soldiers was forbidden surrounded each training area. One section of the Commission dealt directly with the problem of woman and girl camp followers and sought to lessen this evil by work among the women themselves, by securing better enforcement of local police regulations and by educational and reformatory work in camp communities. A great educational program was carried on by the Government by which instruction in sex hygiene was given in the training camps. During the first six months of cantonment training more than a million men were reached in this way, and the work was continued with equal energy throughout the war period.
