to explain them often, until the ears of all are familiar with their practical meaning. The next process is advancing, at a given length of pace in equal times; and this is combined with facings, and at last with wheelings, in whole ranks, or in sections of any given numbers, always varying, diminishing, and augmenting at discretion the numbers of the sections, by drawing from the right of each successive section in the rear of the first, to the left of the leading section, a number sufficient to augment the first to the number required, and so of every section from front to rear; the drill is thus carried on always with moving feet at the time of gay dancing music, and when marching always at a pace of 24 inches. After the squad of 20 or 100 is found complete in these minute branches of marking time, advancing at time, facing and wheeling, augmenting and diminishing sections, they are taught the oblique wheelings and facings, or as the modern words are _half_ or _quarter facing_, or _half_ or _quarter wheeling_; and to march dressed in these several orders, so as to form exactly in the same relative position to each other when wheeled or faced to their primitive position. Thus much may be well taught, and comprehended, and practised in two or three weeks, employing only two or three hours at each drill, and twice each day. The instruction of the pivots or flank men of ranks and sections, go along with the first wheelings; and as soon as the uses of the pivots are generally understood, then the whole are formed into double ranks; and the men are prepared to execute any of the modern evolutions or manœuvres; it being always calculated that the officers are equally diligent and as well drilled as the men, and competent not only to comprehend but to correct an error when it occurs. At this stage, and not before, arms should be put into their hands; and a manual exercise of some kind taught, for it is not material what the motions are so that the firing and loading motions are taught to be performed with dexterity and ease. The drill is then manœuvred once a day with arms, and the officer who feels a proper sense of the importance of the habit of command, and the advantage of giving troops the practice of movement, will diversify his own pleasures and gratify his men, by moving them into all the various positions of column, line, echellons, movements by heads of sections, changing flanks and fronts, taking new alignements, countermarching in the various modes of which modern military works furnish such useful and abundant examples.
