he is called balcor.

      BALL. In a general sense, implies a spherical and round body, whether naturally so or formed into that figure by art. In a military view it comprehends all sorts of bullets for fire-arms, from the cannon to the pistol: also those pyrotechnic projectiles for guns or mortars, whether intended to destroy, or only to give light, smoke, or stench.

      BALLAHOU. A sharp-floored fast-sailing schooner, with taunt fore-and-aft sails, and no top-sails, common in Bermuda and the West Indies. The fore-mast of the ballahou rakes forward, the main-mast aft.

      BALL-AND-SOCKET. A clever adaptation to give astronomical or surveying instruments full play and motion every way by a brass ball fitted into a spherical cell, and usually carried by an endless screw.

      BALLARAG, To. To abuse or bully. Thus Warton of the French king—

      "You surely thought to ballarag us With your fine squadron off Cape Lagos."

      BALLAST. A certain portion of stone, pig-iron, gravel, water, or such like materials, deposited in a ship's hold when she either has no cargo or too little to bring her sufficiently low in the water. It is used to counter-balance the effect of the wind upon the masts, and give the ship a proper stability, that she may be enabled to carry sail without danger of overturning. The art of ballasting consists in placing the centre of gravity, so as neither to be too high nor too low, too far forward nor too far aft, and that the surface of the water may nearly rise to the extreme breadth amidships, and thus the ship will be enabled to carry a good sail, incline but little, and ply well to windward. A want of true knowledge in this department has led to putting too great a weight in ships' bottoms, which impedes their sailing and endangers their masts by excessive rolling, the consequence of bringing the centre of gravity too low. It should be trimmed with due regard to the capacity, gravity, and flooring, and to the nature of whatever is to be deposited thereon. (See Trim.)

      BALLAST. As a verb, signifies to steady;—as a substantive, a comprehensive mind. A man is said to "lose his ballast" when his judgment fails him, or he becomes top-heavy from conceit.

      BALLASTAGE. An old right of the Admiralty in all our royal rivers, of levying a rate for supplying ships with ballast.

      BALLAST-BASKET. Usually made of osier, for the transport and measure of shingle-ballast. Supplied to the gunner for transport of loose ammunition.

      BALLAST-LIGHTER A large flat-floored barge, for heaving up and carrying ballast.

      BALLAST-MARK. The horizontal line described by the surface of the water on the body of a ship, when she is immersed with her usual weight of ballast on board.

      BALLAST-MASTER. A person appointed to see the port-regulations in respect to ballast carried out.

      BALLAST-PORTS. Square holes cut in the sides of merchantmen for taking in ballast. But should be securely barred and caulked in before proceeding to sea.

      BALLAST-SHIFTING. When by heavy rolling the ballast shifts in the hold.

      BALLAST-SHINGLE. Composed of coarse gravel.

      BALLAST-SHOOTING. (See Shoots.) In England, and indeed in most frequented ports, the throwing of ballast overboard is strictly prohibited and subject to fine.

      BALLISTER. A cross-bow man.

      BALLISTIC PENDULUM. An instrument for determining the velocity of projectiles. The original pendulum was of very massive construction, the arc through which it receded when impinged on by the projectile, taking into account their respective weights, afforded, with considerable calculation, a measure of the velocity of impact. Latterly the electro-ballistic pendulum, which by means of electric currents is made to register with very great accuracy the time occupied by the projectile in passing over a measured space, has superseded it, as being more accurate, less cumbrous, and less laborious in its accompanying calculations.

      BALLIUM. A plot of ground in ancient fortifications: called also baiky.

      BALLOCH. Gaelic for the discharge of a river into a lake.

      BALLOEN. A Siamese decorated state-galley, imitating a sea-monster, with from seventy to a hundred oars of a side.

      BALSA, or Balza. A South American tree, very porous, which grows to an immense height in a few years, and is almost as light as cork. Hence the balsa-wood is used for the surf-boat called balsa. (See Jangada.)

      BAMBOO (Bambusa arundinacea). A magnificent articulated cane, which holds a conspicuous rank in the tropics from its rapid growth and almost universal properties:—the succulent buds are eaten fresh and the young stems make excellent preserves. The large stems are useful in agricultural and domestic implements; also in building both houses and ships; in making baskets, cages, hats, and furniture, besides sails, paper, and in various departments of the Indian materia medica.

      BAMBOOZLE, To. To decoy the enemy by hoisting false colours.

      BANANA (Musa paradisiaca). A valuable species of plantain, the fruit of which is much used in tropical climates, both fresh and made into bread. Gerarde named it Adam's apple from a notion that it was the forbidden fruit of Eden; whilst others supposed it to be the grapes brought out of the Promised Land by the spies of Moses. The spikes of fruit often weigh forty pounds.
