the disease will occur beyond herds
which T now infected.
1t is quite probable that there are
herds Of cattle within the State which
have been exposed to infected pas
lures, corrals, roadsides or cattle cars
which have not not yet given eyi.
dence to their infection. For this
reason it would be well for all cattle
raiseB OF the State who suspect any
contamination, to inspect their herds
for cattle ticks, and il found, to pro.
coed with the preventive treatment
recommended below. Tho coming
winter will prabably kill all ticks and
there need be little fear concerning
OH outbreak OF the disease in the fol-
lowing summer. provided no cattle he
imported from California or other in
fected districts after the freezing
weather Is over.
AZ shown by the cattle inspected
and examined at the State line, the
chief symptoms and pathological on.
ditions were rs follows: The disease
first mnnifests itself by fever. dullness,
loss Of appetite and a tendency to
leave tho herd. The temperature
ID from 1O4 degrees Fahrenheit to us
high rs 1915. Tho higher the fever
the soone comes the fatal end The
bowels are usually constipated, but
towards the end OF the curse Of the
disease the dung becomes softer and
yellow from the contained bile. The
urino is passed frequently in consider
able quantities and finally IA the end
approaches becomee dark redfrom the
contained blood coloring matter. The
pulse and respiration are rapid. and rs
the end approaches the muscles CULVER
and the animal finally is unable to
stand and usually dies in commissions.
Infected animals usually die after
from three days to several weeks OF
~illuess. depending upon the severity
Of the disease and the height Of the
fever. Animals which survive the
disease slowly and require
many weeks to regain their flesh
The pathological condition closely
resemble those OF anthrax, showing it
to be a blood disease. A microscopic
examination OF the blood easily dis
eliminates the one disease from tho
other. In anthrax the blood plasma,
or fluid, is thic.Sly crowded with the
bacilli are rod shaped organisms aud

above, the parasitic protozoans areanl
The blood is thin, watery and dark
in color. The spleen, or milt, is greut.
ly enlarged, dark and on cutting it

without it's normal markings. The

a most important thing to I'otice
q the presence OF cattle ticks, which,
[ am told, are rarely seen on native
:attle not infected with the disease.
The treatment is OF a two fold ma.
.urc, viz: First, for the prevention
md second, for the curing OF the dis.
a when nee developed.
Upon the assumption that the
disease ID dependent upon a parasitic
protozoan and upon the basis of the
modern treatment Of malarial fever
n the human, a disease likewise de.
pendent upon suoha parasite, quinine
sulphate was recommended in. large
loses, both for the prevention OF the
lisease and its euro. The treatment
recommended is experimental, but in
,ho luck Of definite and satisfactory
'esults from other and older methods
I was deemed advisable to give it a
trial.
Preventive treatment embraces,
hrst, the removal OF the affected herd,
lick rs we'll rs healthy animals. to new
md non.infected pastures; second, the
lc Jtruction OF the tick by ~currying.
Collecting and burning and by the
duplication Of Insecticides to the parts

bird and as indicated above. the
administration Of quinine sulphate.
To prevent the developemont OF the
