When the tumor has become enlarged, the wool should be removed closely to the skin, the scab scraped with a curry-comb, then wash with strong soap-suds or ley, and afterwards rub thoroughly with sulphur or brimstone, mixed with lard or grease. An effectual remedy is prepared by taking one pound of tobacco, which add to 12 quarts ley from wood ashes of sufficient strength for washing, and four quarts urine; to this add another mixture of a gill high-wines; ¼ oz. camphor; ¼ oz. Spanish brown, and ½ gill spirits of turpentine. A small quantity of this applied to the sore will never fail. Immediately after shearing, scab may readily be cured by immersing the sheep, (excepting the head,) in a strong decoction of tobacco liquor, adding a gill of spirits of turpentine for the first, and making a slight addition of fresh liquid for each sheep, enough to keep up the strength of the tobacco and turpentine, and taking care to rub the affected part thoroughly. For lambs, this liquor should be diluted, but yet left strong enough to kill ticks in one or two minutes, which may be ascertained by experiment. Scab is also removed by using a composition of one pound plug tobacco to three gallons of water, with lime-water and oil of vitriol added; or a decoction of hellebore with vinegar, sulphur, and spirits of turpentine.--(_H. D. Grove._) Scab is propagated more by using the same rubbing posts, than by contact with each other. Sheep in low condition are more subject to it than others. Ticks and Lice Sometimes infest sheep. Good feeding and shelter is a partial preventive, but when they have made their lodgment, they must be dipped in a decoction of tobacco water. The most effectual time for their destruction, is a few days after shearing, when they will have left the naked bodies of the old ewes, to hide in the fleeces of the lambs. The dipping in tobacco water, with the addition of a small quantity of turpentine, is an effectual remedy. After dipping the sheep or lambs, the liquor should be pressed out from the wool, upon an inclined plane, so arranged as again to run into the vessel. Pelt-rot Will be recognised as one of the staple diseases of our _native sheep_, described on page 89. The wool in this case falls off, leaving the sheep partially or almost wholly naked; but this is not accompanied with soreness or apparent disease. The animal must be provided with a warm stall and generous feed, and the naked skin should be anointed with tar and grease. The preventive is good keeping and shelter. Staggers or Sturdy, and Water in the Head, Sometimes affect sheep, but more especially lambs under a year old. The first is caused by the _hydatid_. It is considered as an almost incurable disorder, but is sometimes removed by trepanning. Chancellor Livingston carefully supplied two thus attacked, with food for three months, when nature effected a cure. Removal to dry lands and purging, is a good precaution when they are first taken.
