In angling with caddis, the line, when all out, should be as long as the rod, for three lengths next the hook, of single hairs, with the smallest float, and the least weight of lead, that the swiftness of the stream will allow to sink, and that may be aided by avoiding the violence of the current, and angling in the returns of a stream, or in the eddies betwixt two; which are also the most likely places wherein to kill fish, either at the top or bottom. The caddis may be at times, with very good effect, joined to a worm, and sometimes to an artificial fly, to cover the point of the hook, and also two or three together may be put upon the hook; but it is always to be angled with at the bottom, especially when by itself, with the finest tackle, and at all seasons is a most holding bait for trout and grayling.—_Daniel._ CAG, _s._ A barrel or wooden vessel, made to contain four or five gallons. CAGE, _s._ An enclosure of twigs or wire, in which birds are kept; a place for wild beasts; a prison for petty malefactors. In _Falconry_, the cage is an oblong frame, four feet six inches long and two feet wide, made of light wood, the sides and ends are of a proper size for hawks to perch upon, and a little wadded, that it may not injure their feet. It is supported, when placed on the ground, by four legs, about a foot long. Slight rods of hazel are fixed across each end, to prevent the hawks from falling on the inside when they bait. A space of about twenty inches in length is left in the middle of the cage, in which the falconer places himself, carrying it by two straps that pass over his shoulders. The hawks are tied upon the cage as upon a perch, and by this contrivance many may be carried by one man. Cages and other instruments used in falconry, are well described in the plates of the French Encyclopædia, printed in 1751.—_Sebright._ CAGE, _v._ To enclose in a cage. CAJEPUT OIL, _s._ Is highly stimulating; it is given internally as an antispasmodic, and applied as an external remedy for strains and rheumatism: it may be diluted with olive oil. CALAMINE, (_Lapis calaminaris_,) _s._ A kind of fossil bituminous earth, which, being mixed with copper, changes it into brass. CALCINATION, _s._ Such a management of bodies by fire as renders them reducible to powder: chemical pulverization. CALCINE, _v._ To burn in the fire to a calx or substance easily reduced to powder. CALCULUS, _s._ The stone in the bladder. CALF, _s._ The young of a cow or deer; the thick, plump, bulbous part of the leg. CALIBRE, _s._ The bore, or diameter of the barrel of a gun. CALIDRIS, (_Illiger_,) _s._ Sanderling, a genus thus characterised:—
