286 POULTRY BREEDING 
ROUP, CURE FOR.—The following treatment for 
roup when it has extensively infected the flock is recom- 
mended by the New York Experiment Station: A solu- 
tion is made of one teaspoonful of permanganate of pot- 
ash, dissolved in one pint of water. All the cheesy matter 
is picked off with a toothpick and the spots painted with 
iodine. Then the heads of the sick fowls are dipped in 
the solution. This treatment to be repeated daily until 
a cure is effected. 
ROUP.—Roup is a very contagious disease of poultry 
caused by a specific germ. Some authorities speak of 
roup, diphtheria and catarrh in fowls, but Prof. Philip B. 
Hadley of the Biological Division of the Rhode Island 
Experiment Station classes all the symptoms usually as- 
cribed to these three diseases as different forms of the 
same disease. Stripped of its technical form his descrip- 
tion of roup includes a discharge from the nostrils, the 
eyes, the slit in the top of the mouth, the throat and wind- 
pipe, the disease extending even to the intestines and 
blind gut. If allowed to go unchecked the majority of 
cases terminate fatally from a combination of the poison- 
ous action of the microbes which cause the disease, from 
choking or from a wasting away of the flesh owing to 
internal complications. The specific germ that causes 
the disease has not been definitely isolated, but it appears’ 
to be closely related to the germ that causes white 
diarrhoea in chicks and blackhead in turkeys—not the 
same germ probably but a nearly related one. 
Roup often appears in isolated localities where it could 
hardly have come through infection, and it seems quite 
probable that the germ causing it is everywhere present 
ready to take advantage of favorable conditions to multi- 
ply and become the cause of an epidemic. It would seem
