solution. Fine dust, particularly that which contains 
much powdered air-slaked lime, is often effective in 
destroying lice on fowls; let the birds scratch in it. 
Air-slaked lime should be dusted into the corners and 
crevices of the quarters. Coal-tar applied hot to perches 
and walls, is very effective in keeping away house-mites 
of chickens. 
Very hairy animals are best treated with solu-

remedies is an alkaline coal-tar product which, when 
added to water, produces a permanent milky emul-

does not injure nor irritate the animal. These coal-tar 
products are put on the market under various trade 
names, such as creolin, zenoleum, chloro-naphtholeum, 
sulfo-naphtholeum. They can be used in the proportion 
of one part of the medicine to fifty parts of water, or in 
bad eases one to thirty parts of water. 
Another remedy that gives good results is an in- 
fusion of tobacco, two to three ounces boiled in a quart 
of water. This solution must be used sparingly, as it is 
likely to nauseate the animal. 
Another good remedy is kerosene emulsion, which is 
made by dissolving one quart of soft soap or one-fourth 
pound of hard soap in two quarts of boiling water, and 
adding one pint of kerosene oil. By churning or pump- 
ing violently, then adding three quarts of water, the 
emulsion is made ready for use. Pure kerosene wil!
