 extensively. Lice are the parasites fought and there is no 

 difficulty in controlling them. 



As to frequency of dipping, sheep should be dipped -twice 

 per year lambs and all. Hogs should be dipped whenever 

 it appears necessary, and it will usually be found profitable 

 to dip two or three times a season even though lice may not 

 appear to be present.
