cattle men, posted on the disease, TO
feed salt only in boxes or troughs.
The Oklahoma experimental station
has done some very excellent work
in black leg investigation and their
bulletin on the subject Is extremely
interesting.
Two calves We're placed side BY side
and fed vaccine matter without III
effects. Then a slight cur was made
in ones tongue and both fed vaccine
again. The one died and the other
did not. Then earth mixed with the
vaccine matter was rubbed all over
their hides without effect, but when
a small cut was made in the animals
hides and the rubbing repeated, both
died.
If our experimental station would
do some work along these lines they
would find a fine field, | should like
to see them bury three animals that
died with the disease and after a
year dig down and take some of soil
and rub il in a wound on a yearling
and note the results and keep this up
for several years to determine just
how long the bacili will live, and lose
zone of his de~ath-dealing powers.
This experiment has been tried with
anthrax, a disease very closely akin
to black leg and the bacilli were
found to be alive and deadly ten
years after the animal was buried.
Popular Theories.
One man, when black leg breaks
out in his herd, gets after them with
q whip and a horse and runs them
for two hours.
Another Immediately moves them
to a new pasture.
A third rowels them in the shoulder
with a rag roaked in garlic.

they claim their system a success.
The truth is, that the affected ami
mails died and no more were infected
hence no more died.
All authorities are perfectly agreed
that an animal infected with black
leg bacilli, except where purposely

The disease is extremely prevalent
in France and Switzerland. and 1t
was three French veterinarians who,
in 1883, discovered that by incubation,
animals could be made immune and
later on Kilt a German scientist per-
fected their plan.
How to Prevent Black Leg.
There is but n way and that is
very simple and easy. Vaccinate them
against 1t the same as you vaccinate
yourself against smallpox.
This is done by crowding the ami
mails into a small chute, ten or a
dozen at a time and by means of a
small hypodermic syringe inficting

They can, of course, be thrown and
doctored, but the chute is so much
easier and quicker that 1t should al
ways be used.
Having filled your chute as closely
as you can crowd them. get right
astride of the chute over the animals
and lean down and take up the loose
skin just back of the shoulder or in
front on the shoulder blade with your
left hand. Force the small needle
into and through the skin insert the
needle into the syringe and force
down the piston Of the syringe to the
stop which allows one dose TO enter
the wound.
