the use of blue ointment as a preventative for lice, one great advan- 
tage being the ease of application and permanence. It is usually 
applied by rubbing into the feathers and down around the vent. 
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 
crawl to the fowl and suck blood, returning to their hiding places

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

Scaly Legs.—The form of scabies which affects the legs of 
fowls (Fig. 213) is due to a burrowing insect, which multiplies 
under the scales and secretes a calcareous material. This elevates 
the scales and gives them an uneven appearance, and in some
