DISEASES OF POULTRY. 241 



however, separate all which are apparently sick and 

 put these by themselves. Now saturate the floor of 

 the old house and all of the manure which is about it 

 with one of the disinfectants just mentioned. This 

 may be applied conveniently with a watering can such 

 as is used for watering flowerbeds or gardens. 



The healthy fowls of the flock should be confined to 

 a small run, and this as well as the poultry Thouse 

 should be disinfected by sprinkling at least once a 

 day. The droppings should be swept up, disinfected 

 and removed every day. The buildings should be 

 well whitewashed and the disinfecting effect of this 

 application may be increased by adding one quarter of 

 a pound of carbolic acid to each gallon of lime. 



Eradicating Cholera. — The fowls should be 

 carefully watched and if any show signs of disease 

 they should be removed at once. It is possible to 

 arrest an outbreak of fowl cholera in a very short time 

 by adopting such measures. If they are persevered 

 in for two or three weeks without any more birds be- 

 coming sick the danger may be considered at an end. 



The difficulty of arresting outbreaks of cholera is 

 usually due to the fowls being allowed to roam over 

 an unlimited range. By the time the disease is recog- 

 nized, the contagion is widely scattered through the 

 droppings of the affected birds. It is, of course, im- 

 possible to disinfect a large range, and, consequently, 

 the birds continue to pick up the infection and one 

 after another contract the disease until the greater part 

 is lost. 



If it is decided to kill sick birds in order to get rid 

 of the contagion as rapidly as possible, dig a deep 

 hole, put the birds into it and kill them there, so that 

 their bodies and blood will be buried together. Other-
