but uncomfortable for the fowls from the dust getting into their 

 eyes and mouth. 



Lice may be killed quickly and easily by spraying with crude 

 petroleum. The fowl is suspended by one foot in a looped cord, 

 and the spraying may be done with a simple air-gun sprayer. The 

 process is rapid and very effective. 



Mites (Figs. 211 and 212) differ from lice in that they do not 

 live on the bird's body all the time, but mass together in cracks 

 and crevices under perches and in the walls, whence at night they

 immediate treatment to prevent spread of the mites. 



before the birds leave the perches. When full of blood they are 

 red, hence the name of red mite or red spider. Spraying with 

 strong kerosene emulsion or crude petroleum will kill all the mites

 fowls (Fig. 213) is due to a burrowing insect, which buries itself 

 under the scales and secretes a calcareous material. This elevates 

 the scales and gives them an uneven appearance, and in some
