The demi-vocal signals, directed to be observed in the British service, as far as regards the manœuvring of corps, &c. consist of signals for the government of light infantry, and of cavalry regiments, squadrons, or troops: the latter are properly called soundings. Rifle or light infantry signals are to give notice—toadvance; toretreat; tohalt; toceasefiring; toassemble, or call in all parties. Those signals should be always considered as fixed and determined ones, and are never to be changed. The bugle horn of each company should make himself perfect master of them. All signals are to be repeated; and all those signals which are made from the line or column, are to convey the intention of the commanding officer of the line to the officer commanding the light infantry, who will communicate them to the several companies or detachments either by word or signal.
Signal-staff. In matters of military parade it is usual to fix a flag, somewhat larger than a camp color, to point out the spot where the general or officer commanding takes his station in front or a line. This is called the signal staff.

SILLON, infortification, is a work raised in the middle of a ditch, to defend it when it is too wide. It has no particular form, and is sometimes made with little bastions, half-moons, and redans, which are lower than the works of the place, but higher than the covert way. It is more frequently calledenvelope, which see.
SIMILARpolygons, are such as have their angles severally equal, and the sides about those angles proportional.
ToSIMPLIFY. This word has been adopted amongst men of business and arrangement, from the Frenchsimplifier, which means to relate the bare matter of fact. This signification likewise reaches every species of analysis, &c. Thus the advantage of the new manual over the old, is owing to the reduction of the latter into fewer motions and words of command, by which that exercise has been considerably simplified. The oblique facings, under the denomination ofquarter facings,half facings, of single files; the half wheelings, quarter wheelings, and half quarter wheelings of sections, platoons, divisions, and battalions, are all more simple in the new discipline than the methods of the old.

Sinus, in English, signifies a bay of the sea, an opening of the land; any fold or opening.
SINUSOIDE,Fr.A geometrical curve, which has been imagined by Monsieur Belidor, for the purpose of balancing or preserving the equipoise of a drawbridge. SeeScience des Ingénieurs, liv. iv. See likewise the specific construction of this curve as explained by the marquis de l’Hopital, in a book intitled,Acta Eruditorum, published at Leipsic in 1695; and demonstrated by M. Bernouilli, who discovered that this curve was nothing more than theepicycloid, which see.

SIROC. From Sirius, the dog-star. The wind, which we call south-east, is so called in Italy.
ToSIT. In a military sense, to take a stationary position; as,To sit before a fortified place; to lie encamped for the purpose of besieging it. The French use the wordasseoiras an active verb with respect to military matters, viz.asseoir un camp, to pitch a camp.Il assit son camp hors de la portée du canon de la ville; he pitched his camp out of the range of the town’s cannon.
SIXAIN. Sixth, Sexagena, in war, an ancient order of battle, wherein six battalions being ranged in one line, the second and fifth were made to advance, to form thevanguard; the first and sixth to retire to form therearguard; the third and fourth remaining to form the main corps. The word is derived from the French, which signifies the same thing. The sixain order of battle may be formed with all the battalions whose number is produced by the number six. Twelve battalions, for instance, may be ranged in order of battle, by forming twosixains, and eighteen battalions, ditto by forming threesixains, and so on progressively.
ToSIZE. In a military sense to take the height of men for the purpose of placing them in military array, and of rendering their relative statures more effective. In all infantry regiments the sizing begins from flanks to centre, the tallest men being placed upon the right and left of the several companies in the front rank, and the shortest in the centre and rear ranks. By the old cavalry discipline the flank troops of a squadron must be sized in the following manner: That of the right flank, from right to left; that of the left flank, from left to right; the centre one from centre to flanks; the tallest man must, of course, be always in the part where the sizing begins, excepting the corporals, one of whom must be on each flank of the front rank of the troop, covered by a clever soldier in the rear rank. If there be only two troops in a squadron, they size the right from the left, and the left from the right flank. The modern practice now is to size all troops from the centre, beginning by sizing from the right, doubling and countermarching a rank.
SKEAN,Celtic. A knife. This word is sometimes written skeen, or skeine. It signifies a weapon, in the shape of a small sword or knife, which was anciently worn by the Irish.

SLASHED, cut in stripes or lines. Henceslashedsleeves and pockets, which are peculiar to the British cavalry, when the officers or men wear long coats.
Slashers.A nickname which was given during the American war to the British 28th regiment of foot, and which took its origin from the following circumstance: One Walker, a magistrate in Canada, having, during a severe winter, with great inhumanity, refused to give comfortable billets to the women belonging to the 28th, and some of them having perished in consequence of the inclemency of the season, so great was the resentment of the corps, that some officers dressed themselves like savages, entered his house whilst he was sitting with his family, danced round the table, and suddenly pulling him back upon his chair, cut off both his ears. They instantly disappeared. The deed was not discovered until after their departure. From this circumstance, and in consequence of various intrepid actions which the 28th performed during the course of the war, the men obtained the name ofslashers.

SLING, a leathern strap which is attached to a musquet, and serves to hang it across the soldier’s back as occasion may require.
Gun-Sling, orBelt. Although this useful article owes its invention to the ingenuity of an individual for the convenience of sportsmen, it may nevertheless be adapted with so much facility to military purposes, that a description of it cannot be thought superfluous.
The gun sling or belt is made in the followingmanner:—
The sling consists of three straps of leather, viz. one four feet six inches long, with the breadth agreeable to order. It is pointed and punched at one end, and has a buckle and loop at the other, which serve to shorten or lengthen it as the size of the person may require; another about twelve inches long, and three quarters of an inch wide, with a hook fixed at one end, the first being sewed ten inches from the pointed end of the belt. This strap being hooked up to either of the hooks in the main sling, forms a loop or bearing strap for the barrel of the musquet; and a third three quarters of an inch wide, and about six inches long, with an inch ring at one end, through which the belt is passed. This ring runs conveniently up and down the belt, and fully answers every purpose for which it was designed. A hook is sewed at the other end of this strap; the strap being lapped round the small part of the stock of the musquet, and the hook, fastened to the ring, they together form a loop or bearing strap for the butt. By these means, in addition to the strap round the barrel as already mentioned, the musquet or rifle can be conveniently carried, on foot or horseback, without the assistance of either hand. The musquet being released from these restraints, and the hook fixed to the strap, with the ring, being hooked to a small eye that is fixed just before the guard, the whole is carriedwith very little assistance from either hand, and is instantly brought to a firing position. The next position is by hooking the same hook to an eye that is fixed to the stock, about seven inches behind the guard; the barrel being at the same time supported by the strap, which is hooked to the main belt. The musquet is thus carried without the assistance of either hand; and if there be occasion to fire at a moment’s notice, you have only to draw out the top hook.
Sling.A missive weapon made by a strap and two strings; the stone is lodged in the strap, and thrown by loosing one of the strings.
Slinglikewise means a kind of hanging bandage, in which a wounded limb is sustained.
ToSling, to hang loosely by means of the strap belonging to a firelock.
Slingyour firelocks.A word of command formerly used in the exercise of British grenadiers.
1st. Bring the sling with the left hand opposite to the right shoulder, and the firelock with the right hand opposite the left shoulder, by crossing both hands at the same time, bringing the left hand within the right, keeping the muzzle upright, the barrel to the left, and the right hand just under the left elbow.
2d. Bend the firelock back, and bring the sling over your head, placing it just above your right shoulder.
3d. Draw the sling with your left hand, and let go the firelock with the right at the same time, that it may hang by the sling on the right shoulder, the muzzle upwards, dropping both hands down by your sides at the same time.
Handle yourSlings. 1st. Seize the sling with both hands at the same time, taking hold of it with the right hand about the middle, and as low as you can reach, without bending your body.
2d. With the left hand bring the butt forwards, slipping your left elbow under the firelock, by bringing it between the firelock and the sling; taking hold of the firelock at the same time with the left hand, letting the stock lie between the thumb and fore finger, the butt end pointing a little to the left with the barrel upwards.
3d. Bring the firelock to lie on the left shoulder, and the sling on the right, the barrel upwards, and the butt end pointing directly to the front, keeping the firelock to a true level.

SLUGS. Cylindric, or cubical pieces of metal, used as shot for guns.
SLUICE-gate, a water-gate, by which a place may be inundated, or the water excluded at pleasure.
SLUICES, in military architecture, are made for various purposes; such as to make rivers navigable; to join one river to another, which is higher or lower, by means of a canal; to form inundations upon particular occasions, or to drain spots of ground that are overflowed by high tides; they are also made in fortresses, to keep up the water in one part of the ditches, whilst the other is dry; and to raise an inundation about the place when there is any apprehension of being attacked.
Sluicesare made different ways, according to the uses for which they are intended: when they serve for navigation, they are shut with two gates presenting an angle towards the stream; when they are made near the sea, two pair of gates are made, the one pair to keep the water out, and the other in, as occasion may require: in this case, the gates towards the sea present an angle that way, and the others the contrary way. The space inclosed by these gates is calledchamber.
Whensluicesare made in the ditches of a fortress to keep up the water in some parts, instead of gates, shutters are made, so as to slide up and down in grooves; and when they are made to raise an inundation, they are then shut by means of square timbers let down intocullises, so as to lie close and firm. Particular care must be taken in the building of asluice, to lay the foundation in the securest manner; that is, to lay the timber, grates, and floors, in such a form, that the weather cannot penetrate through any part, otherwise it will undermine the work, and blow it up, as it has sometimes happened: lastly, to make the gates of a proper strength in order to support the pressure of the water, and yet to use no more timber than what is necessary. Those who wish to be thoroughly acquainted with this kind of work, may meet with satisfaction inL’Architecture Hydraulique, par M. Belidor; or in Mr. Millar’sPractical Fortification.
SMALLarms, musquets, fusils, carabines, pistols, &c.
SNAFFLE, a bridle without a curb bit.
SNICKandSNEE, a combat with knives, such as the Dutch carry.
SOBRIETY. General temperance. In a military consideration, abstinence from an inordinate use of strong liquors. However frequent the deviations from this great and uncommon virtue may be found among soldiers, nothing can excuse or exculpate an officer who should so far forget himself, especially upon service, as to give the least countenance to such excesses, even by an occasional, much less by an habitual dereliction of this estimablequality. Sobriety keeps the head cool, strengthens the nerves, and renders moderate abilities equal to great exertions. Drunkenness, on the contrary, unfits the man for the common functions of life, and makes an officer not only contemptible to his soldiers, and dangerous to the cause he has engaged to fight for, but an indirect spur to the enterprise of an enemy, who will soon know how to take advantage of his vice and weakness.
SOC,Fr.A machine made of leather, which is fixed near the stirrup, to receive the end of the standard staff in cavalry regiments.

We conceive it to be immediately taken from the Frenchsoldat, which comes from the Latinsolidarius Veget. A soldier in pay—a solido quem meretur. Some again trace both the English and French word to the Italian Soldato, and others to the German Soldat.Solain German signifies pay. So that originally soldier meant only one who listed himself to serve a prince or state, in consideration of certain daily pay.

SOLIDITY, (Solidite,Fr.) Firmness; density; compactness.
SOLIVE,Fr.A joist.
Solivelikewise signifies a measure in carpentry. It is supposed to be equal to three cubic feet.

The solive is divided into six French feet which are calledpieds de solive. The foot into 12 inches, calledpouces de solive; and the inch into 12 lines, which are calledlignes de solive. In order to form a correct idea of the solive, with regard to all parts or proportions, it must be considered as a parallelepipede, whose base is a rectangle containing 12 inches in breadth, to six in height, and a toise in length, the solive being equal to 3 cubic feet.
SOLIVEAU,Fr.A small joist; a rafter.

SOUND. Any thing audible; noise; that which is perceived by the ear. The experiments are numerous by which it has been found, that sound is audible to the distance of 50, 60, or 80 miles; but Dr. Hearne, physician to the king of Sweden, tells us, that at the bombardment of Holmia, in 1658, the sound was heard 30 Swedish miles, which make 180 of ours: and in the fight between England and Holland in 1672, the noise of the guns was heard even in Wales, which cannot be less than 200 miles.
The velocity of sound is 380 yards, or 1142 feet in a second of time, as found by very accurate experiment. The exactness of measuring distances by sound, has been sufficiently proved by measuring the same distances by trigonometry.
The medium velocity of sound is nearly at the rate of a mile, or 5280 feet in 4²⁄₃ seconds; or a league in 14 seconds; or 13 miles in one minute. But sea miles are to land miles nearly as 7 to 6: therefore sound moves over a sea mile in 5³⁄₄ seconds nearly; or a sea league in 16 seconds.
Sound flies 1142 feet in one second.
It is a common observation, that persons in good health have about 75 pulsations at the wrist in a minute, consequently in 75 pulsations sound flies about 13 land miles, or 11¹⁄₇ sea miles, which is about 1 land mile in 6 pulsations, and 1 sea mile in 7 pulses, or a league in 20 pulses.
The velocity of sound does not very much vary, whether it goes with the wind or against it. As sound moves vastly swifter than the wind, the acceleration it can thereby receive can be but inconsiderable; and the chief effect we can perceive from the wind is, that the sound will be carried to a greater distance by it. Sound will be louder in proportion to the condension of the air. Water is one of the greatest conductors of sound; it can be heard nearly twice as far as on land.
SOUND, (Sonde,Fr.) An instrument used by surgeons in probing.
ToSOUND. To betoken or direct by a sound; as to sound the retreat. Hence
