TO CONTROL LICE AND MITES 303 



tation. Roup, chicken pox, white diarrhoea, cholera, con- 

 junctivitis, and vent gleet are the most common diseases 

 of this class. While the symptoms for each of these 

 are peculiar to the disease itself, the treatment is common. 

 Isolate diseased fowls, kill, and bum their carcasses. In 

 case of large losses, dispose of all fowls and start anew on an 

 iminfected part of the farm. Heavily coat the surface of 

 the old yards with air-slaked lime and plow under. Sow 

 some rank-growing crop. Thoroughly disinfect and 

 whitewash all houses, coops, and equipment. 



Poultry Lice and Mites. — Body lice on poultry need 

 not give the poultr3Tnan any serious concern, for despite 

 all he can do there are likely to be a few on his hens. They 

 can be partially removed by dusting the hens thoroughly 

 with an insect powder. Repeat the dusting in ten days. 

 If this is properly done it should give several months' 

 freedom from the pest. The Uttle red mite which attacks 

 the hens when on the nest or roost is a very real enemy 

 of the poultr37man, but it can be very easily prevented and 

 destroyed by simple and regularly executed disinfecting 

 measures. Simple, cheap, and effective lice and mite 

 killers are made as follows : 



Liquid Lice and Mite Killer — 3 quarts of kerosene to 

 I quart crude carbolic acid. 



Lice Powder — 3 quarts gasoline, i quart crude carboUc 

 acid ; sufficient plaster of Paris to absorb thoroughly the 

 four parts of liquid. Spread the mixture on heavy paper 

 until all liquid has evaporated. Rub it through a screen 

 or fine flour sifter, and it is ready for use. 



Use of Lice and Mite Killer. — For body Uce, paint the 

 perches with the liquid just before roosting time ; or place 

 a piece of brown paper thoroughly saturated with this
