spread by means of infected quarters and fowls. 

 All discharges must be destroyed by disinfection, 

 and the diseased fowls quarantined off by them- 

 selves. The dead should be burned. Keep the 

 quarters light and airy; admit an abundance of 

 sunshine and fresh air. Feed wholesome, nutri- 

 tious food, that the poultry stock may ward off the 

 disease. The best treatment is that which pre- 

 vents spreading to healthy fowls. If an outbreak 

 occurs, disinfect thoroughly, liberally, and continu- 

 ously. Antiseptics administered about the head 

 will usually break up the disease. Creolin is good 

 say, i part to 100 parts of water. Kerosene is also 

 recommended 



In a sense, roup is the result of neglected colds. 

 The birds sneeze, and manifest their uneasiness as 

 animals do with common colds. A teaspoon- 

 ful of pure carbolic acid to each gallon of drinking 

 water is an excellent preventive and can be pro- 

 vided at small cost. 



SAND CRACK. A crack found in any part of 

 the wall of the foot. The crack is due to over- 

 exertion. When the hoof is dry and hard and brit- 

 tle, the crack usually begins at the top and extends 

 downward. Frequently the sensitive tissue creeps 

 into the crack, causing pain, and from which blood 

 frequently issues. When a crack is first seen, the 

 feet should be poulticed with linseed meal for a few 

 days. This will remove the inflammation and 

 soften the hoof. The next step will be to pare out 

 a piece of the hoof at the top, separating it com- 

 pletely from the coronary band a half inch or so 

 on each side of the crack down to the quick. Fill 

 this hole with tar. A bar shoe attached so as not 

 to rest on the wall where the crack is located is 

 yery helpful.
