are numerous cholera "cures" on the market, it is probable 

 that no cure for this disease has yet been discovered. 



When an outbreak of cholera is suspected the sick birds 

 should at once be killed, care being taken that none of the 

 blood is spattered about or allowed to drip on the groimd, as 

 the blood contains the organisms causing the trouble, and 

 will be a means of spreading the disease. Bodies of the birds 

 should then be burned. Burying is dangerous unless it is very 

 deep and the carcass surrounded with quick lime before 

 beuig covered. This is due to the fact that skunks or dogs 

 are likely to dig up the carcasses and spread parts of them 

 about the premises, and even insects working about the 

 carcass are likely to spread the disease. Unaffected birds 

 should be removed at once to new quarters that have been 

 thoroughly disinfected with a solution of 1 pound of carbolic 

 acid to 12 quarts of water. This disinfection of the new 

 premises should be repeated frequently and the birds care- 

 fully watched for further outbreaks. Any birds showing 

 the least sign of the disease should at once be killed and 

 biu-ned. The litter and droppings from the house where 

 the original outbreak occurred should be carefully burned, the 

 premises about the house sowed with hydrated lime, at the 

 rate of 500 pounds to the acre, plowed, and sowed to a crop. 

 When the difficulty has been brought under control and 

 there are no further outbreaks, it is the part of wisdom to 

 market all birds that were, not affected and wait at least one 

 year before attempting to engage further in poultry raising. 

 This is particularly true on the general farm where the 

 birds have the run of the farm, or where the disease is 

 likely to have become widely distributed through the 

 droppings, by the time it is discovered. In such a case 

 it is, of course, impractical to disinfect the whole range, 

 and it will be necessary to depend upon such natural dis- 

 infectants as cold, sunlight, and dryness to accomplish the 

 task.
