After selecting enough of the choicest rams for stock-getters, the castrating may be performed at any time between two and six weeks old, when the lamb is in good health. A cool day should be chosen; or if warm, it must be done early in the morning. The best method is for one person to hold the lamb firmly between his legs, on an inclined plank upon which he rests, while another with a sharp knife cuts off about two-thirds of the lower part of the scrotum. The testicles are then drawn out till the spermatic cord is reached, which is divided by the thumb nail; or it is pulled out and cut with a sharp knife. It is sometimes done by simply opening the scrotum, when the testicles and spermatic cord are jerked out. The wound should then be rinsed with cold water, after which apply lard. The operation of docking 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 this time with the least trouble and without injury. The tail should be laid upon the plank, the person holding him in the same position as before. With one hand he draws the skin towards the body, while the other person, with a two-inch chisel and mallet, strikes it off at a blow, between the bone joints, leaving it one and a half to two inches long. The skin immediately slips back over the wound and is soon healed. Ewe lambs should be docked closer than the rams. To prevent flies and maggots, and assist in healing, it is well to apply an ointment composed of lard and tar, in the proportions of four pounds of the former to one quart of the latter. This is also a good application for the scrotum. The lambs should be carefully protected from cold and wet till they are perfectly well. Tagging, or Clatting, Is the removal of such wool as is liable to get fouled, when the sheep are turned on to the fresh pastures, and of course it should be done just before leaving their winter quarters. It is most easily accomplished by placing the animal on a low table, and then holding it as in shearing, till the operation is performed. All the wool near the extremity of the sheath, and the scrotum of the males; from the udder of the ewes; and from below the dock, the inside of the thighs, and the legs of the sheep, should be removed.
