quarters must be thoroughly cleaned and disinfected, 

 and afterward given a coat of paint or whitewash that 

 will fill all cracks. It is difficult to free animals from 

 lice while in infested quarters. 



When applying remedies to destroy lice, a second ap- 

 plication should be made after five to eight days, to kill 

 the young that may have hatched from eggs laid before 

 the time of the first application. Acid solutions, such 

 as vinegar, one pint to a quart of water, are excellent 

 for destroying ''nits." During treatment the infested 

 animals should be well supplied with good food. 

 For cattle, horses, sheep and pigs, salting frequently 

 with a mixture of one part of sulfur to five parts of 

 common salt is to be recommended. When animals are 

 treated with a solution, in winter, it should be applied 

 on warm days, or the animals kept in a warm place 

 until they are dry. 



In disinfecting quarters, all loose material, litter, 

 etc., should be removed and burned. The quarters, 

 rubbing -posts and other places likely to harbor the lice 

 and "nits" must be thoroughly washed with a good 

 disinfectant, such as a solution of one part of carbolic 

 acid in twenty parts of water, and, when dry, white- 

 washed. Kerosene oil, a strong solution of lye, car- 

 bolic acid solutions and benzine are effective in destroy-

 In using benzine, care must be taken to prevent fire by 

 not bringing a flame into the quarters until the vapor 

 has entirely disappeared. 



Insect-powder is a good remedy to use on fowls, and 

 on other animals when it is not practicable to employ a
