 most popular remedy and perhaps the least dangerous. It is 

 given in the mash for three successive mornings at the rate of 

 one teaspoonful for each 80 pounds live weight of pig. With-

 giving the remedy. 



Sulfate of iron or copperas is a more effective remedy, 

 and is given as follows : Dissolve half a dram of cop- 

 peras in warm water and mix in the mash for each pig 

 for five consecutive mornings, the food being withheld for a 

 short time before giving remedy. In very bad cases and

 every 100 pounds of live weight. The food should be 

 withheld for at least 12 hours before administering the

 cleaned and disinfected, the woodwork whitewashed, the 

 bedding material kept fresh, clean, and dry, and the yards 

 free from accumulations of litter and filth. The hogs should 

 be dipped twice each year in a coal-tar dip, 1 part of dip to 

 50 of warm water, and the treatment repeated in 10 days

To destroy lice, when dipping is not possible, mix equal 

 parts of kerosene and machine oil, or one part of turpentine 

 and two parts of machine oil, and apply to every part of the 

 hog by means of a rag, or swab of cotton waste. It may be 

 applied along the back, from ears to tail, with a common ma-
