This decoction is poured into a deep, narrow box, kept for the purpose, which has an inclined shelf on one side, covered with a wooden grate. One man holds the lamb by its hind legs, while another clasps the fore legs in one hand, and shuts the other about the nostrils, to prevent the liquid from entering them, and then the animal is entirely immersed. It is then immediately lifted out, laid on one side upon the grate, and the water squeezed out of its wool, when it is turned over and squeezed on the other side. The grate conducts the fluid back into the box. If the lambs are regularly dipped every year, ticks will never trouble a flock. MARKING OR BRANDING. The sheep should be marked soon after shearing, or mistakes may occur. Every sheep-owner should be provided with a marking instrument, which will stamp his initials, or some other distinctive mark, such as a small circle, an oval, a triangle, or a square, at a single stroke, and with uniformity, on the sheep. It is customary to have the mark cut out of a plate of thin iron, with an iron handle terminating in wood; but one made by cutting a type, or raised letter, or character, on the end of a stick of light wood, such as pine or basswood, is found to be better. If the pigment used be thin, and the marker be thrust into it a little too deeply, as often happens, the surplus will not run off from the wood, as it does from a thin sheet of iron, to daub the sides of the sheep, and spoil the appearance of the mark; and, if the pigment be applied hot, the former will not get heated, like the latter, and increase the danger of burning the hide. Various pigments are used for marking. Many boil tar until it assumes a glazed, hard consistency when cold, and give it a brilliant, black color by stirring in a little lampblack during the boiling. This is applied when just cold enough not to burn the sheep's hide, and it forms a bright, conspicuous mark all the year round. The manufacturer, however, prefers the substitution of oil and turpentine for tar, as the latter is cleansed out of the wool with some difficulty. It should be boiled in an iron vessel, with high sides, to prevent it from taking fire, on a small furnace or chafing-dish near which it is to be used. When cool enough, forty or fifty sheep can be marked before it gets too stiff. It is then warmed from time to time, as necessary, on the chafing-dish. Paint, made of lampblack, to which a little spirits of turpentine is first added, and then diluted with linseed or lard oil, is also used. The rump is a better place to mark than the side, since it is there about as conspicuous under any circumstances, and more so when the sheep are huddled in a pen, or running away from one. Besides, should any wool be injured by the mark, that on the rump is less valuable than that on the side. Ewes are commonly distinguished from wethers by marking them on different sides of the rump.
