solution. Fine dust, particularly that whieli 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- 

 tions that destroy the lice outright. One of the best 

 remedies is an alkaline coal-tar product which, when 

 added to water, produces a permanent milky emul- 

 sion, that is very efficient in destroying parasites and 

 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 cases 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 will 

 usually take the hair off, and should not be used un- 

 less it is washed off at once.
