There is not a vacant moment in which to be bored. Work is knocked off for an hour towards mid-day to let the men eat the rations which the drafts have brought in their haversacks from their quarters at the base depôt camp of the division to which their battalion belongs. But a band begins to play from the moment of dismissing, and it also gives priceless help in keeping up march discipline and smartness on the few route marches for which there is room in the course. Defence against Gas. A detail, which needs care and gets it, is instruction in self-defence against gas. Lachrymatory gas is comparatively a trifle. The men are practised in walking through an open trench full of the heliotrope smell of the gas, and come out shedding tears and laughing at the far end. The more serious poison gas is let loose in a tunnel-like chamber through which every officer and man bound for the Front must pass. The foul stuff in the chamber is some hundred times as dense as any gas to be met in actual warfare. But if the man’s gas mask is in order, and he uses it as he has been told, he suffers no inconvenience while passing through or afterwards, and thenceforward no German gas has any terrors for him. Varied Lessons. The photographs bring out many interesting details in the training course. One of them shows, in a night scene, how skilfully the general atmosphere of the Front, as well as the details of trenches and craters, is reproduced for purposes of instruction. Another shows non-commissioned officers receiving instruction by the help of “picture targets” in the indispensable art of describing any point in a landscape exactly and tersely. In a photograph of the bayonet fighting course the Indian soldiers’ firm balance of the body and excellent carriage of the head are noticeable. Sandbag-Filling. Speed in sandbag-filling, for trench fortification purposes, is extremely important; in some battalions it is encouraged by systematic competitions, the competitors working in pairs. Note, in the photograph of men aiming or loading, in a lying position, the uniformity with which their heels are kept down. In a badly trained draft several heels would be sticking up, inviting enemy bullets. Swedish Drill.
