baths. This is nature's method and is effectual 

 if the fowls will bathe thoroughly. Many of the 

 heavier fowls, however, do not care to take dust 

 baths frequently, nor to do the work thoroughly 

 whan they undertake it; consequently it is fre- 

 quently necessary to use artificial methods to kill 

 or drive away the lice, when they once become 

 well established on adult fowls. Powdered sul- 

 fur -or fresh insect powder dusted well among 

 the feathers is found to be efficient. Fowls are 

 sometimes placed in comparatively tight boxes 

 with their heads protruding through close-fitting 

 openings, the box then being filled with sulfur 

 fumes for several minutes. This is said to com- 

 pletely destroy the pests and in no way to injure 

 the fowls. 



When poultry houses become infested with lice 

 a complete cleansing of the building is required. 

 Movable fixtures should be taken 'out and the 

 walls thoroughly washed and cleansed. The in- 

 terior should be freshly whitewashed or sprayed 

 with chlorides or other efficient insecticides. 

 Kerosene emulsion is effective if the spraying is 

 thoroughly done. Some modern spraying ma- 

 chines are so constructed that kerosene oil may 

 be mixed with water in a fine spray to answer 

 every purpose. This method is easier than to 

 apply the kerosene in the form of a soap emul- 

 sion.
