Proof Furnished by King.
n Kings work leads 20 the proof
that spirochetes are the cause Of hog
cholera much viii have been accom-
pilahed because the disease will have
been classified with other spirochete
diseases. such as nagana which af-
fects cattle ana horses In Africa. is
carried by tho tsetse ny. and has pre-
vented the development OF a large
part Of Africa.
But the cause Of hog cholera,
whatever it may be. we do know that
every biz Of the fluid In a hog sick
Of cholera is viruient even to the
tears. The urine. the feces. the
blood and flesh are all virulent.

Lives Only in Hogs.
The germ that causes hog cholera
cannot be cultivated artihcially nor
will u live in any other animal long
enough TO cause diseases People
need not fear to eat pork that comes
from hogs that have had cholera
when killed.
The disease cannot be quarantined
when one considers farm
conditions and the possible ways of
transmitting the disease II may be
carried from farm TO farm on the
feet OF a farmer or of an animal A
farmer who has healthy hogs should |
not walk into the hog lots or pasture |
where cholera is known to exist. A |
hog that has died OF cholera and been
buried may even after year be quite
virulent. Dogs and crows are apt |
TO carry around pieces OF such a car

The veterinary OF the Indiana serum
plant tells me that an Indiana Ear

owned. had his herd infected by
means OF dog dragging a piece OF
, carcass OF a hog TO his hog pas
