remains active until shortly before the fowl dies. 

 This disease may also be controlled by the prop- 

 er sanitation of poultry houses. Likewise with 

 "going light," a disease in which diarrhea 

 appears and the affected fowls drag on until all 

 the muscle disappears. This trouble may some- 

 times be checked by giving laxatives like castor 

 oil followed by tonic foods. Gapes in young 

 chickens may be cured if the owner has time to 

 bother with the trouble by applying turpentine to 

 the inside of the throat with a feather. Occasion- 

 ally forcing chickens to inhale irritating gases will 

 make them cough so as to expel a portion of the 

 gape worms which are attached to the inside of the 

 windpipe. Since it appears that this worm gains 

 entrance to the chicken from the bodies of angle 

 worms upon which chickens feed it is desirable 

 during the first few weeks to keep chickens on dry 

 board floors and not allow them access to garden 

 soil where they may get worms. 



Chicken pox, or Sore Head may be treated by 

 painting with iodine or washing with a weak 

 solution of potassium permanganate. The places 

 where chickens are kept sometimes becomes fear- 

 fully infested with lice and other insect pests. It 

 is necessary to wage continual warfare against 

 these vermin in the warmer climates. This may 

 best be accomplished by isolating the roosts as far 

 as possible from other structures in the hen houses, 

 spraying them occasionally with kerosene and 

 spraying the walls of the hen houses with kerosene 

 emulsion at intervals of two or three weeks. This 

 is quite effective and is comparatively inexpensive.
