The object of _docking_ is to keep the sheep behind clean from filth and vermin; since the tail, if left on, is apt to collect filth, and, if the animal purges, becomes an intolerable nuisance. The tail, however, should not be docked too short, since it is a protection against cold in winter. This operation is by many deferred till a late period, from apprehension of too much loss of blood; but, if the weather be favorable and the lamb in good condition, it may be performed at the same time as castration with the least trouble and without injury. The tail should be laid upon a plank, the animal being held in the same position as before. With one hand the skin is drawn toward the body, while another person, with a two-inch chisel and mallet, strikes it off at a blow, between the bone-joints, leaving it from one and a half to two inches long. The skin immediately slips back over the wound, which is soon healed. Should bleeding continue--as, however, rarely happens--so long as to sicken the lamb, a small cord should be tied firmly round the end of the tail; but this must not be allowed to remain on above twenty-four hours, as the points of the tail would slough off. Ewe lambs should be docked closer than rams. To prevent flies and maggots, and assist in healing, it is well to apply an ointment composed of lard and tar, in the proportion of four pounds of the former to one quart of the latter. The lambs should be carefully protected from cold and wet till they are perfectly well. [Illustration] FEEDING AND MANAGEMENT FEEDING. As soon as the warm weather approaches and the grass appears, sheep become restive and impatient for the pasture. This instinct should be repressed till the ground has become thoroughly dry, and the grass has acquired substance. They ought, moreover, to be provided for the change of food by the daily use of roots for a few days before turning out. The tendency to excessive purging which is induced by the first spring-feed, may be checked by housing them at night and feeding them for the first few days with a little sound, sweet hay. They must be provided with pure water and salt; for, though they may do tolerably well without either, yet thrift and freedom from disease are cheaply secured by this slight attention. As to _water_, it may be said that it is not indispensable in the summer pastures, since the dews and the succulence of the feed answer as a substitute; but a wide experience having demonstrated that free access to it is advantageous, particularly to those having lambs, it should be considered a matter of importance on a sheep-farm so to arrange the pastures, if possible, as to bring water into each of them.
