cIRcUMvENTING THE CATTLE

Fro1. w. II. Dalrymple of the Louis
lana station, in an address to Me-
braska stockmen, said:
We in the South consider. so far "a

we might also say, those of the North

most valuable discovery ever made. is.

AS has been previously limited. the
actual, or exciting, cause of Texas
fever is germ-a malarial type of
germ-belonging to the protocol, the
lowest form of animal life. Technic-
ally, this organism is known as "piro-
plasma bigeminum," and it can be
found within the red blood cells of
any of our native southern cattle that
have been exposed to tick infestation.
1t may be. Of interest to state at
this point that we have Southern ma
t1ves, however, that are non-immunes.
This may appear rather strange to
some of you, as it did to many. in
Guiding some Of our leading stock
journals, when South Carolina herd
of cattle became infected with Texas
fever after exhibition at the Charles
ton Exposition in 1901. The explana-
ton OF such an occurrence, however,
Is quite simple, when we realize that
the tick is, so far as we know. the
only intermediary host of the disease
germ, and that there are many places
in the southern states, as, for ex-
ample, the alluvial lands of my own
state, or lands subject to periodic
inundation, on which ticks are rarely
to be found. Consequently animals
born and raised on such tick-free
places are non-immune, because they
have not had the opportunity to be-
come inoculated by the natural meth
cd, VIZ, through the intermediation of
the tick. But, if animals so raised
are afterwards placed upon ticky pas
lures, they will contract the fever
just as surely as if they had been i'm
ported from North of the Federal
Quarantine Line. In short, it is, with
us, a question of ticks, or no ticks.
