gfcrms of other diseases such as roup, etc., and is a process that 

 a hen house should have every fall and spring to keep diseases 

 from the fowl. 



CHOLERA. 



Cholera is very contagious. The cause of it is overcrowding, 

 bad sanitary management, unwholesome or irregular food, etc. 

 Chicken cholera is not very well understood by poultry raisers, 

 and we believe it is a fact that a great many diseases are called 

 cholera simply because it is not understood. Everyone who 

 keeps fowls should be able to tell cholera from other diseases, for 

 without such knowledge it is impossible to treat the disease 

 properly. 



Symptoms. — The fowl has a very sleepy, droopy appearance ; 

 it is very thirsty and has a slow gait and gapes often. Some- 

 times the fowl staggers and falls down from great weakness. 

 The comb and wattles lose their natural color, generally turning 

 pale and sometimes they are dark. There is diarrhoea with a 

 greenish discharge, or like sulphur and water. The crop fills 

 with mucus and wind, and at last the food is not digested. 

 Breathing is heavy and fast, the eyes close, and in a few hours 

 the fowl dies. 



Treatment. — The first thing to be done when cholera makes 

 its appearance is to give the coops and yards a thorough 

 renovating ; disinfect with carbolic acid, 40 drops to the pint of 

 water. Remove all affected fowls and burn the carcass of dead 

 ones. The best and most effective remedy for cholera that we 

 have ever used is coal oil or kerosene. The coal oil should be 

 given about four times a week, as follows : Take a feeding of 

 corn and wheat and let it soak in the oil a few hours, and then 

 feed it to the fowls, or mix it in soft food, one teaspoonful of oil 

 lio every two quarts of corn meal. While treating do not give 

 Tiuch water to drink. 



CANKER. 



Canker is caused by filthy quarters and musty or unwhole- 

 some food. Canker may be noticed by running sores on the 

 tiead, in the mouth or throat accompanied with a watery discharge 

 from the eyes. 



Treatment. — Take warm water and a little salt and wash the 

 head and eyes, also swab out the throat and mouth. Remove
