period of a month or longer.

_The tissue changes_ occurring in the disease are inflammation of all or a
few of the internal organs. Ward states that the most characteristic lesion
of fowl cholera is the severe inflammation of that portion of the small
intestine nearest to the gizzard. Small hemorrhagic spots may be found on
the heart and other organs.

_The treatment is both preventive and curative_. The preventive treatment
consists in quarantining newly purchased birds until we are satisfied that
they are free from disease. The occasional disinfection of the poultry
houses and runs is highly important. Cleaning the poultry house by removing
the floor, roosts, or any part of the house for the purpose of removing all
filth, and spraying the interior with a three per cent water solution of a
cresol disinfectant, should be practised. Lime should be scattered over the
runs, or the yards immediately about the house. The above preventive
measures form an important part of the care and management of the flock.
The carcasses of the dead birds should be burned. It is advisable to kill
all birds that are fatally sick.

All of the flock should be given antiseptics with the feed and water. Four
ounces of a water solution of copper sulfate, made by dissolving
one-quarter pound of this drug in one gallon of hot water, may be added to
each gallon of drinking water. Frequent disinfection of the drinking
fountains, feeding places and houses should be practised.

DISEASES RESEMBLING FOWL CHOLERA.--There are a few diseases, such as
septicaemia, limber neck and infectious enteritis, that are sometimes
mistaken for fowl cholera. These diseases are caused by different
microorganisms that may be found in the digestive tract and air-passages of
