with a 5 per cent solution of crude carbolic acid followed by a

Hogs often suffer from lice. The insects are most numerous 

 around the ears, inside the legs, and in the folds of the skin. 

 In light cases they may be destroyed by washing the hogs with 

 a broom moistened with an emulsion of kerosene and water, 

 or by using a stock dip. In severe cases the whole herd should 

 be dipped. If the herd is badly infested, the bedding should 

 be burned and the loose boards and partitions of the quarters 

 removed and the whole place disinfected with crude carbolic 

 acid followed by a coat of whitewash. 



The mud-wallow too often seen in hog yards should be done 

 away with and a concrete wallowing place provided. This 

 should be about fourteen inches deep and be built under cover 

 of a shed. The ground surrounding it should be surfaced with 

 crushed rock or concrete to prevent the formation of mud- 

 holes. The tank should be partly filled with water and should 

 be cleaned whenever it becomes dirty. Crude oil poured on 

 the water will keep the hogs free from lice. 



210. Hog cholera. This is by far the most serious disease 

 of hogs. It destroys about 90 per cent of all the hogs that die 

 of disease in the United States. Nearly 7,000,000 hogs have 

 died in one year and the money loss has averaged about 

 $30,000,000 a year for the past forty years. Hog cholera is 

 highly contagious and is caused by a germ which is carried easily 

 from sick animals to healthy ones. 



Methods for the prevention and treatment of the disease 

 are fully outlined in Farmers' Bulletin 834 and this pamphlet 

 should be secured and studied carefully by all those particularly 

 interested in the subject. The following statements are from 

 this bulletin : 



With the object of assisting the farmer to protect himself the fol- 

 lowing suggestions are offered : Hog houses, lots, and pastures should 

 be located away from streams and public highways, and the houses 

 and lots should be arranged so that they may be cleaned and dis-
