weather. Washing or dipping the animal with a two per cent water solution
of liquor cresolis compositus is an effective remedy for the psoroptic
forms of scab and mange. Tobacco, lime and sulfur, and arsenical dips are
recommended in the treatment of sheep and cattle. Ointments are recommended
for animals that are slightly affected with mange. Lime and sulfur dips are
recommended by the Bureau of Animal Industry. Small infected areas of the
skin may be treated by applying sulfur-iodide ointment. The following
ointment is commonly recommended: potassium sulfide ten parts, potassium
carbonate two parts, and lard three hundred parts.

Sheep cannot be safely dipped for scab during the cold weather. If
thickened and scabby, the skin should be scrubbed with the dip, or the
animal prepared for dipping or washing by first clipping the hair or wool
and scrubbing the skin with water and a good soap. In order to prevent
reinfection, it is necessary to remove the animal to new quarters, or
thoroughly clean and disinfect the old. It is necessary to wash or spray
the fences, floors, walls, brushes and curry-combs with a disinfecting
solution. Manure and other litter should be removed to a place where there
is no danger from its distributing the infection.

DISEASES OF POULTRY CAUSED BY MITES.--Mites or acarina that cause diseases
of poultry may live on the feathers, beneath the skin, and within the body
of the fowl.

_The small, red mite (Dermanyssus gallinae)_ remains on the surface of the
body only when feeding, and spends the rest of the time under collections
of filth and in cracks in the roosts and walls of the house. This parasite
causes the birds to become restless, emaciated and droopy.

_A very small mite (Sarcoptes mutans)_ is the cause of scaly leg. It lives
