146 : DISEASES OF THE HOG. 
become a rough sore. This disease is contagious 
from one pig to another. It generally appears first. 
on the thin parts of the skin under the arm, behind 
the ear, inside of the thighs and upon the back. 
This disease in the early stage resembles eczema, 
but if the eyesight is goodand assisted by the bright 
sunlight, the parasites may be seen as a moving 
white Speck, but can be readily seen by a small 
. Magnifying glass. The cause of this disease is by 
contagion; that is, the parasites themselves or 
their eggs must get on the skin in order to produce 
the disease. It is therefore necessary that all the 
unaffected pigs should be removed from the prem- 
ises where the diseased ones are or have been, and 
the wood work of the sties washed with a strong 
solution of carbolic acid. 
Treatment: Wash the pigs all over with soft 
soap and water, then rub in well dry sulphur. When 
the sulphur comes in contact with secretions from 
- the sores, it forms a compound poisonous to the . 
parasites. Ina day or two give the animal another 
washing, and rub on some more sulphur. A very 
sure remedy is to boil for one hour two ounces of 
stavesacre seeds in one and one-half quarts of 
water, and keep it nearly boiling for an hour 
longer; make up the water to the quantity original- 
ly used. Such a solution, rubbed into the skin, not 
only kills the parasite, but its eggs also. Repeat 
in a week, if necessary. Another is to steep one 
part of tobacco in twenty parts of boiling water for 
a few hours, and, after washing the pig, apply a 
little of this to the affected parts with a sponge.
