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, 
ete., 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, ear- 
bolic acid solutions and beuzine are effective in destroy- 
ing parasites about the quarters of infested animals. 
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
