and sulphur, mix well and put into the food once a day, a tablespoonful 
to three pints of scalded meal. Another renedy: Two taklespoonfuls of 
epsom salts, four of lime, and ten drops of tincture of iron, put into a 
gallon of meal. Again, coal oil is highly recommended, a few drops being 
put into the food, and is well worth a trial. The simple treatment of con- 
fining the fowls to a stiff paste of flour and water is of questionable efficacy, 
though it doubtless tends to lessen the rapidity in the action of the bowels, 
and, since it will thus retard the prostration, the paste may be used asa part 
of the food. 
To well fowls, and those slightly affected, give in the food a little 
‘sulphur, soda, cayenne pepper and tincture of iron, a different one each day, 
and add carbolic acid or fluid carbolate to the drink. As food for both of 
these classes good authority favors warm boiled potatoes mashed up with 
bran (or wheat, oatmeal, or barley meal) and sour milk, mixed with a 
little pulverized charcoal and bicarbonate of soda. If the Douglass Mix- 
ture is added to the food, it will have a good effect on the well birds. Asa 
preventive, nothing has been found that is better than coal oil, or kerosene, 
which may be given by soaking grain in it several hours before feeding it, 
or by mixing a tablespoonful in a half-gallon of cornmeal. Powdered 
charcoal in small quantities, put into the feed, will have a favorable tend- 
ency. For obvious reasons lice and mites should be kept away, the food 
be digestible and regularly given, the surroundings be absolutely clean, and 
all hygienic measures be observed to keep up the tone of the system. 
ROUP.—CROUP.—_ASTHMA.—_YAWS. 
Roup is the second of the two most dreaded diseases of fowls and is, 
therefore, given the second mention. It is a highly contagious malady 
which first affects the lining membrane of the beak and then extends to 
the eyes, throat and whole head, eventually involving the entire constitu- 
tion. According to its more manifest symptoms, it has been called diph- 
theria, sore head, swelled eyes, hoarseness, bronchitis, canker, snuffles, influ- 
enza, sore throat, quinsy, blindness, and by other names, though some of 
these are hereafter treated as separate diseases. It attacks all ages, but the 
older birds more readily. It occasionally kills young ducks and turkeys. 
Causes.—Filth, poor shelter, bad food, indeed anything which reduces 
the tone of the system will favor the development of the disorder. Ex- 
posure to wet and cold, and neglect of slight diseases of the nose, mouth, 
and air-passages are prolific sources of the ill or at least conditions inviting 
its appearance. It follows from the last remark that prompt attention to 
other less malignant disorders may prevent much trouble and save many
