A chaplain was appointed to every cadet-company, whose duty it was to instruct the cadets in reading and writing. They had likewise a master in mathematics, a drawing master, a fencing master and dancing master. CADET, _Fr._ likewise means any officer that is junior to another. CÆMENT, CEMENT, among engineers, a strong sort of mortar, used to bind bricks or stones together for some kind of moulding; or in cementing a block of bricks for the carving of capitals, scrolls, or the like. There are two sorts, i. e. hot _cement_, which is the most common, made of resin, beeswax, brick dust, and chalk, boiled together. The bricks to be cemented with this mixture, must be made hot in the fire, and rubbed to and fro after the _cement_ is spread, in the same manner as joiners do when they glue two boards together. Cold _cement_, made of Cheshire cheese, milk, quick lime, and whites of eggs. This _cement_ is less used than the former, and is accounted a secret known but to very few bricklayers. CÆSTUS, in military antiquity, was a large gauntlet, composed of raw hides, used by pugilists at the public games. CAGE _de la Bascule_, _Fr._ a space into which one part of the draw-bridge falls, whilst the other rises and conceals the gate. CAIC, _Fr._ a skiff or boat belonging to a French galley. CAIMACAN, in military history, an officer among the Turks, nearly answering to our lieutenant. CAISSE, _Fr._ _Battre la caisse_ is used in the French service to express the beating of a drum instead of _battre le Tambour_. CAISSON, in military affairs, is a wooden frame or chest, made square, the side planks about 2 inches thick: it may be made to contain from 4 to 20 loaded shells, according to the execution they are to do, or as the ground is firmer or looser. The sides must be high enough, that when the cover is nailed on, the fuzes may not be damaged. _Caissons_ are buried under ground at the depth of 5 or 6 feet, under some work the enemy intends to possess himself of; and when he becomes master of it, fire is put to the train conveyed through a pipe, which inflames the shells, and blows up the assailants. Sometimes a quantity of loose powder is put into the chest, on which the shells are placed, sufficient to put them in motion, and raise them above ground: at the same time that the blast of powder sets fire to the fuze in the shells, which must be calculated to burn from 1 to 2¹⁄₂ seconds. When no powder is put under the shells, a small quantity of mealed powder must be strewed over them, having a communication with the saucisson, in order to convey the fire to the fuzes. CAISSON, is a covered waggon, to carry bread or ammunition. CAISSON, _Fr._ is variously used in the French service.
