It is a great object, not only as a matter of propriety and honesty, but even as an item of profit, to get the wool clean, and of a snowy whiteness, in which condition it will always sell for more than enough extra to offset the increased labor and the diminution in weight. The average loss in American Saxon wool in scouring, after being washed on the back, is estimated at thirty-six per cent.; and in American Merino forty-two and a half per cent. CUTTING THE HOOFS. As the hoofs of fine-woolled sheep grow rapidly, turning up in front and under at the sides, they must be clipped as often as once a year, or they become unsightly, give an awkward, hobbling gait to the animal, and the part of the horn which turns under at the sides holds dirt or dung in constant contact with the soles, and even prevents it from being readily shaken or washed out of the cleft of the foot in the natural movement of the sheep about the pastures, as would take place were the hoof in its proper place. This greatly aggravates the hoof-ail, and renders the curing of it more difficult; and it is thought by many to be the exciting cause of the disease. It is customary to clip the hoofs at tagging, or at or soon after the time of shearing. Some employ a chisel and mallet to shorten the hoofs; but the animal must afterward be turned upon its back, to pare off the crust which projects and turns under. If the weather be dry, or the sheep have stood for some time on dry straw, as at shearing, the hoofs are as tough as horn, and are cut with great difficulty; and this is increased by the grit and dirt adhering to the sole, which immediately takes the edge off from the knife. These periods are ill-chosen, and the method slow and bungling. It is particularly improper to submit heavily-pregnant ewes to all this unnecessary handling at the time of tagging.
