CARTRIDGE, a case of paper, parchment, or flannel, fitted to the bore of a piece, and holding exactly its proper charge. Musket and pistol cartridges are always made of strong paper, between 30 and 40 of which are made from 1 pound of powder, including their priming. Ball cartridges should be made of a different coloured paper to what is used for blank. The French musquet ball-cartridges are all capped with flannel. Cannon and howitzer cartridges are sometimes made of parchment, though more generally of flannel: the charges they contain are adapted to the service they are intended for. Cartridges for cannon, are made with the best effect, when the flannel does not admit the leakage of powder; to effect this the flannels are first sewed to the size of a mandril or wooden roller; and the sewing completed, the end is tied, and hammered on the end of the mandril, the whole is then smeared with a coat of paste made of wheat flour and gum; and then drawn over, so that the pasted side may be inward; then set to dry, before filling they must be examined. The experiment is worth the trial of making cartridges of cotton saturated with alum; its cheapness, its abundance, and easy formation, all recommend it. The alum would render it fire proof. CARTRIDGE-_Box_, a case of wood, made in a circular form, to wear before the body of the soldier, holding 24 or more musket-ball cartridges in rows: it is covered with leather, and worn upon a belt, both on duty, and on the day of battle. See POUCH. The light infantry in the French service carry a cartridge box in front which covers the abdomen; and contains several rounds; some carry the cartridges on the side one above the other. CARTRIDGES for guns.
