As result Of perfecting serum that
IL an antitoxin against hog cholera the
Missouri Agricultural college at Co
lumbla guarantees the state legislature
that with an appropriation of $4,000
year II win save the farmers of Mis-
souri, from 100000 to $5,OOO,0OO an,
nually from the ravages of this dis
ease.
The serum was discovered by DIR. M.

ment Of agriculture, but 1t was perfect
ed and made practical by DIR. J. w.
Connoway Of the Missouri Agricultural
college. He has been working for
months on the problem and now has
the proportion exactly.
The Agricultural college announces
unequivocally that It is prepared to
vanquish that bane Of the farmer, hog
cholera. The discovery, which has been
tested and proved, will mean to the
animal world what antitoxin means to
humans and will reduce the price Of
pork to a minimum.
The Agricultural college here Is re-
ceivlng letters from agricultural insti-
tutions and experiment stations all
over the country inQuiring the results
obtained and asking for samples Of the
serum and instructions in its applica-
ton.
BY the improved method hogs are
lmmuned against cholera and out
breaks of the disease are stopped with
only the loss Of those animals that
died or became seriously affected be-
fore the identity OF the disease was
discovered, and thus the spread Of the
disease from one herd to a whole
ueighborhood and from a neighbor.
hood to other sections Is stopped, and
the immense amount of money that
10 lost annually by the farmers. II
changed into profits.
The serum, or blood, is drawn from
what Is known as a hyperlmmunlzed
hog, the flbrln being removed so as
10 prevent CLOTHING. The serum Is
treated with small quantities Of car
bollc acid and when kept in a cool
place can be preserved from six to
twelve months. When hogs are to be
inoculated an assistant from the Agri.
cultural college injects from tea
spoonful to a tablespoonful into the
ham Of the animal
A hyperimmunized hog Is produced
by FIRST giving the cholera to a well
hog and at the time injecting into him
q small amount Of the serum. In
about ten days after he has recovered

hogs suffering with cholera IL inject

Of ten days or two weeks. each time
increasing the dose OF infected blood
until as much as a quart or a quart
and a half Ii injected without affect

This amount Of infection injected
into the hog at one time is sufficient
