recent conference OF Federal and State
officials in charge Of hog cholera work,
the methods OF supplying the serum in
practice were considered. There are
two methods: In one, the serum alone
is used, producing immunity lasting
from thirty to ninety days; in the other,
the virus OF hog cholera and the serum
are injected simultaneously, that is,
virus at one point and serum at anofh-
er. This latter is known as the Stimuli
taneous Method, and will produce ac-
tive or lasting immunity. If the serum
used in this simultaneous treatment is
not good, or il the mode Of application
is faulty, disease may be set up in the
treated herd. For this reason it was the
general concensus Of opinion at the con-
ference that the simultaneous method
should be used only by those who have
had special training, and it was agreed
that the ideal arrangement would be to
allow its use only by Federal and State
veterinary officers.
The serum alone treatment, on the
other hand, may be given by anyone
without danger OF causing hog cholera.
II the serum is good the farmer may
give It to his hogs without fear, proyid-
ed it is administered in the proper way.
While it would no doubt be best to have
even the serum alone always admins
tered by skilled agent, farmers may
obtain good results il proper care is
used. The farmer should remember
that the serum alone treatment is very
different from the simultaneous treat
ment The following advice regarding
the use OF serum is offered for farmers
who can not obtain the services OF a.
skilled agent;
All serum cannot be depended upon,
and farmers are cautioned against put
ting implicit confidence in serum
merely because it is labeled Anti-Hog-
The serum must be pre-
pared right in order to protect hogs.
Farmers should use every effort to get
a good reliable serum from the State
College or from reliable dealer.
Anti-hog-choIera serum is most effec-
live when used as preventive. It will
also cure large number OF hogs in the
Early stages of the disease. 1t is Of !
much less value, however, for hogs that
ire yisibly sick. The farmer should
make careful preparations before be-
ginning the incubation. Hogs that are
lick should be separated from the we'll

The pen or inclosure where the injec-
ions are made should be clean and free

hypodermic syringe. Before begin
