DISEASES AND PARASITES OF FOWLS 395 



crude carbolic acid. Spray as above or use whitewash brush 

 for applying it. 



Treatment 4. Where lime sulphur spray is used for 

 fruit trees it may also be used for spraying the poultry 

 house. If thoroughly done this should control the mites. 



Lice. Lice are not so injurious as the mites but they 

 must not be allowed to breed unchecked. Unlike the mites 

 they do not suck the blood but subsist upon the productions 

 of the skin and the feathers. They live and breed on their 

 host. There are three kinds of lice generally recognized. 

 First, those that are found on the head and neck of the 

 fowl and especially on young chicks. The scientific name 

 is Goniodes eynsfordii. Second, the wandering lice 

 (Menopon pallidum). These are found on different parts 

 of the body. Third, those found between the barbs of the 

 wing and tail feathers (Liperurus variabilis). 



The conditions which encourage the breeding of these 

 lice are filth, dampness and darkness in the poultry house. 

 The eggs are laid among the feathers and attached to them, 

 especially to down feathers. They hatch out in from six to 

 ten days, the time varying. Lice will live several months 

 without the hen or host. Theobald reports keeping Menopon 

 pallidum for nine months on fresh feathers, they apparently 

 eating the quill epidermis. 



Dust Bath. Domestication of the hen can be carried so 

 far and no farther, and this fact must ever be remembered. 

 It might seem a little more sanitary or civilized for the hen 

 to keep her body clean by using a white enameled bath tub 

 provided with hot and cold water taps, or to have a chicken 

 barber shop where a weekly shampoo may be had, but the 

 hen prefers to wallow in the dust of the road or in a crude 

 box filled with dust, that is not by any means germ-proof. 

 It would be as easy to make water run up hill as to change 

 the nature of the hen when it comes to her method of keep-
