    "abstract": "The first interest displayed by the United States Army in motion pictures was in the field which, at the time, it shared in common with the rest of the world, the field of amusement. During the early history of the motion picture, the Army was concerned solely with the entertainment value of pictures and motion picture shows were to be found in every Army post. Even under canvas in the field, the troops had picture shows. They were welcomed by officers and enlisted men alike. I doubt if there has ever been devised a method of entertainment that more perfectly meets the demand of the military for sane and wholesome recreation than the motion picture. In most commands, a bugle call announced the hour of pictures. In my experience only one other call awakened more general interest, in the command—the one known to all soldiers as “Pay Day”, announcing the presence of the paymaster in camp.",
