Drills, or the assembly calls for them, came at the following hours: 8:15, 9:30, 10:45, 1:00, and 2:15. At 3:30 came a school of instruction, which lasted an hour. There was guard-mount, too, which is another sort of drill, at 5:00. This lasted half an hour, and mess call for supper sounded shortly after 5:30, followed by retreat, meaning that the main part of the day was over. From supper time till the call to quarters, which sounded at 9 P.M., the recruit was allowed to do about as he pleased, though sometimes there was instruction in the evening. The call to quarters was the signal for all lights to be out in the squad room, though it was not necessary for all the soldiers to be there at that hour. They were, however, expected to be there at ten o’clock when taps were sounded, this being a bugle call for all lights to be out, and every one in bed, except the officers and sentries. “Well, I don’t see where we’re going to have an awful lot of time to scrabble around and have fun,” said Bob, in a half-growling tone, as he looked over the printed list of the camp schedule. “We have from four-thirty to five-forty-five with nothing to do, if we’re not in the guard-mount stunt, and then we have time after supper. But that isn’t much.” “Say, what do you think you’re on--a vacation?” asked Jerry. “Well, no, not exactly,” answered Bob slowly. “Not exactly! I should say not! Most emphatically--not! You’re here, and so we all are, to do our duty and beat the Germans, and if it takes all day I’m willing!” went on Jerry. As has been mentioned there are many kinds of drills in the army, but the new recruits, such as Ned, Bob, and Jerry, found, according to their squad leader, that the physical drill was the most important one for them at first. Later on would come rifle drill, drill in the trenches, bayonet practice, machine gun drill, rushes with hand grenades and so on. There seemed to the boys to be no end to it. The boys of course, began at the very bottom to learn about army work, and one of the first things they were told was in regard to different formations, or units. The squad is the smallest unit of the infantry, to which branch of the service the three chums were attached. A squad consists of eight men, seven privates and a leader, who is, generally, a corporal. This squad is the foundation of the army, and the members of it generally stay together, sleeping, eating and fighting in unison with other squads. After the squad comes the platoon, which is made up of from two to six squads, and the men are in charge of a lieutenant with a couple of non-commissioned officers to help him. Four platoons make a company, and this is in charge of a captain, with two lieutenants to aid him.
