The disorder is communicated by the absorbents of the foot coming in contact with the suppuration which has been left on the ground from the diseased part. Absolute safety against this contagion is secured only by a total avoidance of the walks of the infected animals, till repeated rains, or what is better, frosts, have disarmed the virus of its malignity. _Remedies_ are variously compounded, of blue vitriol, verdigris, tar, spirits of turpentine, alum, saltpetre, salt, lime, copperas, white-lead, antimony, alcohol, urine, vinegar, &c., all of which have proved effectual. The hoof should first be pared and thoroughly scraped. Then apply a wash made of three parts of blue vitriol, one of verdigris pulverized finely, with scalding (not boiling) vinegar; stirring briskly till it is of the consistence of thin cream, and put it upon the affected part with a paint brush. It is a good preventive, to apply this to the sound feet of the affected animal. Another remedy is to use spirits of turpentine after scraping; and if the disease is of long standing, add to the turpentine a strong decoction of blue vitriol dissolved in water. The foot should be examined every week, and the remedy repeated till perfect soundness is restored. A feather dipped in muriatic or nitric acid, and applied to the parts after scraping and cleansing, is a good remedy. When put upon the soles of _foot-sore_ sheep, it hardens the hoofs, and enables them to travel better. Sheep are sometimes cured by keeping them on a dry surface, and driving over a barn-floor daily, which is well covered with quicklime. It may also be cured by dryness, and repeated washing with soap-suds. The above ailment should not be confounded with a temporary soreness, or inflammation of the hoof, occasioned by the irritation from the long, rough grasses which abound in low situations, which is removed with the cause; or if it continues, apply white paint or tar, after thorough washing. Corrosion of the Flesh by Flies or Maggots, May be cured by first removing the vermin; then wash with Castile soap and warm soft water, after which apply white-lead with linseed oil. Tar put on the festering wound corrodes it; but this, or spirits of turpentine placed on the sound parts near it, keep off the flies by their strong effluvia. If the wound be slight, and the weather moderate, apply a little spirits of turpentine with a strong decoction of elder bark. Flies on Sheep May be prevented by smearing with a composition made of two pounds lard or soft grease, one pound sulphur, half pint oil of amber, or oil of tar, or tar alone. A small spoonful is sufficient for a sheep.--_Genesee Farmer._ Protection from the Gad-Fly.
