The outward flank man looks to his rank. regulates his pace at which the wheel is made, and conducts the flank s as to avoid crowding on the flank. the men resisting pressures f In the outward and yielding to pressures from the inward flank; the rear rank must reili back at the pivot, and partly passage and incline towards the wheeling flank, in order to cover. In wheeling on the move, both flanks are kept in motion; the inner flank describing an arc of a lesser circle; the outer flank de- scribing an arc of the large circle, and moving about one-half faster than the rate at which the body is niarching; the inter- mediate men conforming to the movements of the flanks: pres- sure must be yielded when coming from the side towards the guide, and resisted from the opposite side, whether the guide be on the pivot or on the marching flank. In the evolutions, the wheelings are on a fixed pivot; in changes of direction in col- umn. the wheels are made on the move, so as not to retard the march, the arcs described by the pivots are five paces. and when marching in column of four, or twos, the pivot wheel without slacking the pace; the wheeliugs should be first prac- ticed in single rank; in wheeling f'rom line into column, the lrcssing after the wheel is to the marching flank. ALIG.\’ME.\'TS. The three right files of each rank are placed four paces for- ward and aligned. BY FILE—RIGHT Dnnss. -- The men of each rank advance singly and dress on the men of their respective ranks already established, taking care not to pass beyond them, and feeling the touch of the boot gently to the right. Fuoxr.—The men turn their heads to the front. Dressing back is practised in the same manner. After the men are suffi- cicntly practised to align by file, they are taught to align by the whole rank at once by the command RIGHT DRESS. There are three paces, the walk. the trot, and the gallop. The walk at 3% or 4 miles an hour. The trot at 8% miles an hour. The gallop is not considered applicable to general purposes of manoeuvre, though it may be uspd ocqasionally for very simple formations. The rate of charge should not exceed the speed of the slowest horses. To preserve uniformity of movement, the trot and gallop should commence gradually. and by the whole body at the same time. The pace. by which intervals are measured, is one yard. As in infantry tactics, the commands are of two kinds—those of caution and those of execution. They should be given in a firm and clear tone, and repeated by the chiefs of subdivisions. There should be a short pause be- tween the command of execution. At thecommand of caution, the chiefs of subdivisions will caution their subdivisions as to the particular movement which each has to perform. The com- mands march and halt should be instantly repeated by chiefs of subdivisions. When 9. line breaks from a halt by a wheel the chief of each subdivision will judge of the instant when the movement ought to finish to order halt, and left or right-dress. At the word march, a line or column will move at a walk, unless the command indicates a different pace. When a command ‘s not distinctly heard by some part of the line. each officer. when the indication is obvious, will conform quickly to the movement which he has seen executed on his left or right according to the point from whence he perceives it to be given. Cavalry is said to be marching by Files when each front-rank man has his rear-, rank man following him, the whole is one single string. Cav- alry is marcliing by twos, when each front—ra.nk two has its rear- ‘rink two following it, being a column two abreast. When each .'ront-rankfour has its rear-rank four by its side, being a column of 8 abreast, Cavalry is said to be marching by fours. Fou .9 must not be confounded with sections of fours, which is when each frontrankfour, has its rear-rank four following it, being a column of four abreast. PLATOCN is the fourth part of a squadron. Platoons in sqad- ron are numbered first, second, third, fourth, from the right. Two companies form a squadron, and are termed the right and left companies. Two or more squadrons compose a corps or re- giment. The "ordinary distance at which the rear-rank is formed behind the front-rank is one yard at pace, and is termed close order. The increased distance taken by the rear-rank on some occasions, is termed open order, and is 6 paces. The extent of the front of a squadron is to be calculated at about as many yards as it contains files. From one horse to another when marching in files,.—twos, fours, or section of fours, the distance is one yard. From one squadron to another in close column, the distance is ten yards or paces. Distance from one squadron to another in close column, ten ards. y Distance from one squadron, company or platoon, to another, in open column—the extent of front of each squadron, company or platoon, taken from front-rank to front-rank, adding 10 paces for the interval between squadrons when in line. The depth of two ranks, taking the length of the fullest sized horses at eight feet, and the distance between the ranks at three feet, is to be reckoned at about 19 feet. Intervals between squadrons, are ten paces; between regiments fifteen, when in line. Tue directing flank of a column is that which guides cover in marching. When the column is marching with the ri ht in front, the left is the directing flank; except under peculiar cir- Jumstances or manceuvres, the right is the directing flank with the left in front. The directing flank is indicated by the com- mands, guide left or guide right, as the case may be, and the dressing is towards that flank. Pressure must be yielded when coming from that flank, and resisted when coming from the opposite flank. Every division that Is to be aligned upon another, will halt abreast of the rear rank, parallel to the line of formation, to move forward into the alignment of the division already formed. In'uersz'on——W hen the squadrons are not in their proper order; or when the right are to the left, and the left to the right. Oblique Echellon——A line broken into several parts by wheels from line or column, less than the quarter circle, so as to be oblique to the former front, but parallel with each other. .When the lines of the open spaces are perpendicular to the lines of the several parts the echellou is termed direct.

Those movements are intended for the passage of defiles, and will be executed by the sub-divisions in successions, at the same given point. In diminishing from platoons to sections of fours and so down to files, it will be necessary first to halt the column, in order to avoid crowding and confusion, which would, otherwise, obvi- ously arise from the want of space necessary to execute the movements.
