The poles or rails for stack-pens or hay-holders should be so small as to entirely prevent the sheep from inserting their heads in them after hay. A sheep will often insert his head where the opening is wide enough for that purpose, shove it along, or get crowded, to where the opening is not wide enough to withdraw the head, and it will hang there until observed and extricated by the shepherd. If, as often happens, it is thus caught when its foreparts are elevated by climbing up the side of the pen, it will continue to lose its footing in its struggles, and will soon choke to death. TAGGING. Tagging, or clatting, is the removal from the sheep of such wool as is liable to get fouled when the animal is turned on to the fresh pastures. If sheep are kept on dry feed through the winter, they will usually purge, more or less, when let out to green feed in the spring. The wool around and below the anus becomes saturated with dung, which forms into hard pellets, if the purging ceases. Whether this take place or not, the adhering dung cannot be removed from the wool in the ordinary process of washing; and it forms a great impediment in shearing, dulling and straining the shears to cut through it, when in a dry state, and it is often impracticable so to do. Besides, it is difficult to force the shears between it and the skin, without frequently and severely wounding the latter. Occasionally, too, flies deposit their eggs under this mass of filth prior to shearing; and the ensuing swarm of maggots, unless speedily discovered and removed, will lead the sheep to a miserable death. Before the animals are let out to grass, each one should have the wool sheared from the roots of the tail down the inside of the thighs; it should likewise be sheared from off the entire bag of the ewe, that the newly-dropped lamb may more readily find the teat, and from the scrotum, and so much space round the point of the sheath of the ram as is usually kept wet. If the latter place is neglected, soreness and ulceration sometimes ensue from the constant maceration of the urine. An assistant should catch the sheep and hold them while they are tagged. The latter process requires a good shearer, as the wool must be cut off closely and smoothly, or the object is but half accomplished, and the sheep will have an unsightly and ridiculous appearance when the remainder of their fleeces is taken off; while, on the other hand, it is not only improper to cut the skin of a sheep at any time, but it is peculiarly so to cut that or the bag of a ewe when near lambing. The wool saved by tagging will far more than pay the expenses of the operation. It answers well for stockings and other domestic purposes, or it will sell for nearly half the price of fleece-wool.
