PREVENTIVE AND CURATIVE TREATMENTS. 
As mentioned, the truly rational treatment of black leg is 
one calculated to prevent it, but, of course, it will break out 
here and there unexpectedly, in new places where the germs 
exist unknown to the people, in spite of any and all precau¬ 
tions unless it be inoculation. Therefore it does become nec¬ 
essary to attempt to limit outbreaks after their appearance, if 
one is so unfortunate as to be a sufferer thereby. 
The first thing to do in the case of black leg is to remove 
at once from the place where the malady started, all the stock 
showing no sign of the disease and leave the sick ones there. 
Place the apparently well ones on higher and dryer lands if 
possible, or in a yard, or open, well-ventilated stable, and feed 
them dry fodder for a week or so and give them plenty of 
good, clear water—not filthy, stagnant pond or pool water. 
During that period if you can procure black leg vaccine 
properly prepared, inoculate every subject twice, i. e. at six 
or eight days interval, and then nearly all, if not absolutely 
all, will be in a position to resist the germs of black leg, no 
matter where exposed and where they may find them.* 
On the belief that only the fattest and best conditioned 
calves or young cattle become affected, it has been suggested 
that a treatment calculated to impoverish the system would 
in a measure prevent black leg. It is partly on this basis that 
a change of pasture to a poorer one is recommended, and 
partly because by such practice the animals may be.excluded 
from infectious soil. But on the same principle of impover¬ 
ishment, the use of setons, or so-called rowels, has been pre¬ 
scribed. It causes copious suppuration and thereby a drain 
is established on the vital elements of the body. This, by the 
way, may not sound scientific enough for some of the stand¬ 
ing authorities ; nevertheless, there is some reason in it, and 
seemingly, some good results from such practice are not ex¬ 
ceptional. 
*Any man of ordinary intelligence can safely practice this vaccination or in¬ 
oculation. All that is necessary is good virus and a hypodermic syringe.
