"Boil the ingredients together for fifteen minutes. * * * * The liquid is in no degree injurious to wool. It cleans and dries the offensive perspiration of the sheep, and destroys the smell caused by the dew in the mornings, or by damp hot weather. In most situations, one dressing in July and another in August will suffice; but as the expense is trifling, and the process simple, it may be better to apply it more frequently, especially in low and damp situations." The liquid is applied only in dry weather. A teapot, or any vessel of a similar form, is filled with it, and one person pours it on the wool, while another rubs the fleece to facilitate the passage of the fluid. At the times of using the solution, all superfluous wool ought to be shorn from the buttocks, but not too closely. When the insects are very troublesome, drive the sheep if possible to higher ground. Examine carefully all wounds and ulcers, however trifling, and dress them with any simple ointment containing a small proportion of sulphur, mercury, or white-lead. Lastly, bury all useless carcasses as speedily as possible, by which means you will keep down the number of the flies. (149.) _The Sheep-Fag or Ked_ (_Hippobosca ovina_) and _The Tick_ (_Acarus reduvius_), are destroyed or stopped in their attacks by the same remedies and preventives detailed in the preceding paragraphs on the fly. (150.) _Inflammation produced by the OEstrus bovis._ This insect infests not only cattle but also sheep and goats, depositing its eggs on the back of the animal, where it forms a small tumour, in which the larvæ remain from autumn till the commencement of the ensuing summer. Only the fattest and most vigorous animals are attacked, and the larvæ are very difficult to destroy. Fischer found, from numerous experiments, that even spirits, and a strong solution of salt, could not affect them. The fumes of burning sulphur alone seemed to annoy them, and to it they speedily fell victims. This, however, is a remedy which cannot be applied to the skin of the sheep, so that our only resource is the repeated application of turpentine to the tumours on the back, taking care to slit them up so as to facilitate its action. (151.) _Sore Teats._ When a ewe is observed to hinder the lamb from sucking, its teats should be examined. If much inflamed, a poultice should be applied, and the lamb placed under the charge of another nurse. Suppuration will thus be promoted, and the matter may be allowed to escape by making an opening for it at the place it points. If there is only a little tenderness of the skin, all that is required is the washing it with a solution either of sugar of lead or sulphate of zinc, eight grains to the ounce of water.
