323 PROFITS IN POULTRY. 
and full of sores. Next, the liver becomes spotted, and 
covered with round, yellowish patches. Young turkeys 
are attacked. Many die in July and August and in 
the fall, Thesymptoms are, diarrhea, roughened feath- 
ers, and purplish or ‘‘black” head. The disease spreads 
from one bird to another. 
Dr. Theobald Smith, of the U. 8. Bureau of animal 
industry, recommends the disinfection of the coops and 
other structures designed to give shelter to turkeys. 
The following disinfectants are strong enough to kill 
spores of bacteria : 
(a) Corrosivé sublimate (mercuric chloride), one ounce 
in about eight gallons of water (one-tenth of one per 
cent). The water should be put into wooden tubs or 
barrels, and the powdered sublimate added to it. The 
whole must be allowed to stand for twenty-four hours, 
so as to give the sublimate an opportunity to become 
entirely dissolved. Since this solution is poisonous, it 
should be kept covered up and well guarded. It may 
be applied with a broom or mop, and used freely on all 
woodwork. Since it loses its virtue in proportion to the 
amount of dirt present, all manure and other dirt should 
be first removed before applying the disinfectant. The 
manure should be covered with lime. 
(4) Chloride of lime, five ounces to a gallon of water 
(four percent). This should be applied in the same way. 
(c) The following disinfectant is very serviceable. It 
is not poisonous, but quite corrosive, and care should be 
taken to protect the eyes and hands from accidental 
splashing: Crude carbolic acid, one-half gallon; crude 
sulphuric acid, one-half gallon. 
These two substances should be mixed in tubs or glass 
vessels. The sulphuric acid is very slowly added to the 
carbolic acid. During the mixing a large amount of 
heat is developed. The disinfecting power of the mix- 
ture is heightened if the amount of heat is kept down
