Treatment.—First clean the sores, removing all dirt, scabs, etc. For this purpose, olive oil is better than water, as soap and water are apt to cause further irritation. Apply Zinc Ointment night and morning. Give A.A., three times per day, for two days, then I.I. instead of A.A.
Warbles
This is often seen on cattle in February and March. It consists of a number of roundish swelling from five to twenty in number, usually on the back and sides. The swellings are sometimes as large as the closed fist.
During the summer months the gadfly lays its eggs on the skin of the cattle, especially just above the heels. The cattle bite these places and swallow the eggs; which hatch into larvæ and make their way through the body to the skin, where they form these swellings. The swellings suppurate and form a small hole, through which the larvæ breathe and later escape. After the larvæ have escaped the swellings subside.
Treatment.—Warbles may be prevented by keeping the cattle from swallowing the eggs. Either by brushing off the legs, or by applying kerosene oil, or a 3% solution of creoline, or one of the proprietary products for keeping flies off cattle. This should be done night and morning during July and August.
The larvæ may be killed as soon as the hole is first formed; by injecting kerosene oil from an ordinary oil can into the aperture, or by covering the hole with thick grease, which prevents the larvæ from breathing. When the larvæ are killed the swelling usually soon disappear.

Diseases of Sheep and Goats
When a number of Sheep or Goats, or a flock, are to receive medicine, the best and most economical, as well as efficient method, is as follows: Procure a new or perfectly clean pint bottle and cork, fill it two-thirds full of pure water, to which add a large spoonful, or sixty drops, of the proper remedy, SHAKE IT THOROUGHLY, so as to perfectly medicate the whole mass. Of this a dessert spoonful is a dose for a sheep or goat. Paste a proper label on the bottle and use it only for that remedy, so as to prevent mistake or confusion.
