DISEASES AND PESTS. 82% 
ure, and one drop of the last dilution is equally as deadly 
as the original drop of blood from the diseased fowl. 
‘The disease first makes its appearance in the urates, 
giving them a yellowish cast. These discharges, as the 
disease advances, gradually become more frequent and 
copious, and the bird becomes weaker, sometimes living 
several days, and often dying in twenty-four hours. 
Fowl cholera is not only the most fatal, but the most 
contagious of all poultry diseases. 
Now, as every part of these excrements is filled with 
the microscopic life of the cholera, it will be seen how 
necessary it is to thoroughly clean and disinfect the 
building and confine the affected fowls by themselves. 
In an experiment, some time since, a number of dis- 
eased fowls were confined by themselves, and fed on soft 
food into which was mixed a smull quantity of medicine 
composed of equal parts of asafcetida, hypophosphate 
of soda and saffron, ground together, a little cayenne 
pepper being sprinkled in the food also. The drinking 
water was treated with the Douglas mixture. Three- 
fourths of the fowls thus treated recovered. In another 
lot, simply confined and fed without any treatment, the 
disease proved fatal in every case. 
The great point is to avoid contagion. Deodorize 
everything in connection with the buildings, and have 
all infected matter burned. This alone will destroy the 
minute organism of fowl cholera. 
BLACKHEAD OF TuRKEYS.—An infectious disease of 
the intestines and liver, commonly known as blackhead 
of turkeys, has prevailed very extensively in Rhode 
Island, Massachusetts, Connecticut, and probably also 
in other turkey-raising districts, although the disease 
has been scientifically investigated in the New Fngland 
sections only. The disease is caused by a small parasite, 
which first attacks the cecum or pronged part of the 
lower bowel, causing it to become thickened, enlarged,
