The power of crottle can never be known but by length of boiling; for which reason, get the largest copper pot you can. It ought to hold thirty or forty quarts; then put three quarts of crottle in, and fill it with water. Separate the wool according to the number of shades you wish for, put it into as many bags, and let them boil _eight whole days_, or _as long as you can stay_ out of bed. You may draw a bag every six hours, and if you wish lighter shades, sooner. You are to get a round thin deal board, (see there is no turpentine in it,) bore it with holes that will receive your fingers, put your lid over that, and be careful of keeping your pot full of water. After three days’ boiling, you must put in two quarts more crottle, to bring up your dark shades. I followed this plan for a whole six days, and I got the finest colours my eyes ever saw. I got so high a shade as a rich claret brown under; and it was a very rich cinnamon over head. The reason I have mentioned eight days is on account of the bags, which prevent the dye. I also mention a copper pot, and you must use no other in any dye. I never could clean the crottle properly out of the fur for want of being in bags. Strong muslin bags will answer much better; particularly as by using them the operator may enjoy his bed _four nights_ out of _the eight specified_.—_Ancient Recipe._ CROUP, _s._ The rump of a fowl; the buttocks of a horse. CROUPADES, _s. obs._ Are higher leaps than those of curvets. CROW, _s._ A large black bird that feeds upon the carcases of beasts; a piece of iron used as a lever; the voice of a cock, or the noise which he makes in his gaiety. This species weighs about nineteen ounces; length eighteen inches; bill black; irides dusky. The whole plumage black, glossed above with a purplish blue; legs black. Distinguished from the rook by the bill, which is rather more convex towards the end, and the nares, or reflected bristles, at the base being always perfect; but these are only obvious in adults. In young birds the note is the only criterion of distinction, which in this is much more hoarse than that of the rook. The crow feeds on flesh, insects, and grain; but is particularly fond of carrion. It frequently attacks the eyes of dying animals, and destroys weakly lambs; it will also pursue birds on wing, when pressed by hunger. We once saw this bird in pursuit of a pigeon, at which it made several pounces, like a hawk; but the pigeon escaped, by flying in at the door of a house. We have also seen it strike a pigeon dead from the top of a barn. It is a great destroyer of young game and poultry. It is a bold bird, always at war with the lesser species of hawks; nor does the kite, the buzzard, or the raven, approach its nest without being attacked and driven away. At that season, even the peregrine falcon is insulted, who frequently at one pounce brings it to the ground.
