146 DISEASES OP THE HOG. 



become a rQUgh sore. This disease is contagious 

 from one pig to another. It generally appears first 

 on the thin parts of the slcin 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 good and 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. In a 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.
