In marching, the soldier must maintain, as much as possible, the position of the body as before directed. He must be well balanced on his limbs; his arms and hands must be kept steady by his sides; and he must not be allowed to stoop forward, still less to lean back. His body must be kept square to the front, and thrown rather more forward in marching than when standing still, so that it may accompany the movement of the leg and thigh, which movement must Spring from the haunch; the ham must be stretched, but without stiffening the knee; the toes a little pointed outwards, and kept near the ground, so that the boot-soles may not be visible to a person in front. The head should be kept well up, without stiffening the neck, and straight to the front, and the eyes not suffered on any account to be cast down; the foot, without being drawn back, must be placed flat on the ground. The length of each pace, from heel to heel, is thirty inches; and the recruit is taught to take seventy-five of these steps in a minute, without tottering and in perfect steadfastness. This is the ordinary step, being the pace on all occasions whatever for both infantry and cavalry, unless greater celerity be particularly ordered, which is called the "quick step," and the "double," or run. Each individual recruit is very carefully trained and thoroughly instructed in this part of his duty, as it is considered to form the basis of the proper deportment of the soldier. In the regular army, where men are enlisted from all grades of society, it requires the most unremitting perseverance and accurate knowledge of the part each instructor has to teach, as also a clear and concise manner of conveying his instructions, allied to a firmness that will command from all classes of men a perfect attention to the directions he is giving them. He must allow for the weak capacity of the recruits, and exercise patience and good-temper, without rigour, where endeavour and good-will are evidently not wanting. Quickness in military drill is not at first required, because it is the result of much practice; but if officers and instructors are not critically exact in their commands, and in observing the execution of what is required from others, slovenliness must take place, labour will be ineffectual, and the end proposed will never be attained. The recruit must be carried through his drill progressively; he should comprehend one thing perfectly before he is required to learn another.
