 posed both to the fonl gaseous emanations, and to the 

 germs which abound in putrefj-ing excreta. 



Treatment.— The prevention of the filth diseases 

 is much easier than their cure, and this malady is no 

 exception to the rule. Cleanliness, good food, pure 

 water and ventilation are conditions antagonistic to 

 the propagation of infectious leukicmia. With these 

 conditions, it has been found difficult to keep up the 

 disease experimentally, and it has not been found 

 upon premises where they exist. 



When this disease appears the poultry -houses 

 should be cleaned and whitewashed The floors 

 should be sprinkled with carbolic acid in solution of 

 five-per-cent strength. Other efficient disinfectants 

 may of course be used if more convenient. The sick 

 fowls must be removed and isolated. Quinine in the 

 dose of 1 to 2 grains has been suggested for the sick 

 fowls. Sulphate of iron (copperas) in the drinking 

 water is thought to be a good prophylactic remedy. 

 Probably any stimulating and tonic treatment will 

 prove beneficial after proper sanitary surroundings are 

 secured. 



It has been found experimentally that the germ is 

 killed in five minutes by a one -per-cent solution of 

 carbolic acid, and in ten minutes by lime water. 

 Sulphur fumes were also effectual by three hours 

 treatment. It is, also, destroyed by a temperature of 

 136.4 degrees F., and, consequently, ])oiling water 

 may be used to cleanse drinking and feeding troughs 

 and other infected articles. As the disease appears to 

 be one of the most common to which fowls are sub- 

 ject, there should be am])le opi)ortunities to make
