Tkkatmknt. — The eradication of tui^erculosis in 

 birds from an infected premises can f)nly be attempted 

 with a fair prospect of success when all the birds are 

 sacrificed. Any individuals that are preserved are 

 liable to have ulcerations of the intestines, from which 

 the l:>acilli are constantly distributed. There should, 

 consequently, be no attem]-)t to save any birds from an 

 infected flock. 



When the birds are all killed and disposed of by 

 burning or deeply burying, the premises should be 

 carefully disinfected. The manure should be carefully 

 scraped and swept together and saturated with a five- 

 per-cent solution of carbolic acid or mixed with lime. 

 The floors and woodwork of the houses should be 

 washed with boiling water or with a hot solution of 

 carbolic acid. The feeding troughs, drinking vessels 

 and nests should be treated in the same manner. Any 

 yards used for penning birds should be sprinkled with 

 the carbolic acid solution. 



After the cleaning and disinfection is accomplished 

 the premi.ses should be opened to the sun and air for a 

 month if possible before new birds are introduced. It 

 is then a good plan to cover the walls and roosts with 

 lime wa.sh, to which 4 ounces of crude carbolic 

 acid to the gallon has been added, and ventilate a few 

 daj'S longer before the houses are used. Tho.se who 

 scrupulously enforce these measures may be reason- 

 ably certain that the contagion will be destroyed and 

 that the new flock may be safely introduced.
