come one large tumor. When pressure
is exerted over the swelling a cracking
sound is distinguished, and tapping on
it produces a clear. resonant sound, due
to a collection of gas in the affected
tissues. The tumor is invariably cool to
the touch and painless in the center,
but the skin over it is dry and hard. IF
the swelling is cut open, it emits a dark
red fluid, frothy in nature, and no pain is
shown when the i~ncision is made. If the
temperature is taken with a clinical
thermometer, it will frequently be found
reaching as high as 40 per minute.
THERE'S a trembling of the muscles,
which sometimes deyelopes into violent
commissions on the approach of death.
The animals which die from blackleg
should be Immediately burned or buried
than six fee, ard lime should be scatter
ed freely over the space where the ami
NAL was l ing before being buried.
Blackleg vaccine has proven, in over
fourteen years of use, to bo an absolute
preventive of this disease. Every cattle
man, therefore, who has his own welfare
at heart, should, upon the first appear
ance of the disease in his locality, im-
mediately proceed to vaccinate all cattle
under two years of age and above six
months. For vaccination, the following
things are required: An anti-toxine
syringe, with at least four or five extra
needles, as it will be found the needles,
by a beginner, are often broken; a small
mortar and pestil; small glass funnel; a
package OF filter papers, a breaker, glass,
and an open mouth bottle or common
water glass, IN which to filter the vac
cine. A quantity of water should be
boiled thoroughly and allowed to cool
aud absolute cleanliness must be prac-
tlced in everything pertaining to the
operation. Each package of vaccine
contains enough for ten animals, and
the anti-toxine syringe should be one Of
the large size, which are usually gradu-
ated for twelve doses of vaccine. Empty
out a package of the vaccine into the
mortar; draw the water up into the
TO the 40" mark, and it is al
ways well to draw up a little more than
enough for ten, so that in excluding the
air from the syringe there will still re-
main a full measure of ten doses. Eject
sufficient water into the vaccine to wet
1t; then take the pestil and thoroughly
grind and mix the moistened vaccine,
gradually adding the water from the
syringe until the doses of water are
thoroughly mixed with the vaccine mat
tLen folding the filter paper careful
10 fit the funnel, place it il the glass
funnel and moisten with some OF the
boiled water, this being for the purpose
Of having the same amount of vaccine
when filtered as you had before measur-
ing. II not to be used immediately, put
1t IN a cool place until you desire 10 use
it, but no vaccine should be prepared
+han four or five hours before it is
needed, and then it should be carefully
covered, to prevent any outside Infection.
When ready to use draw the full ten
doses into the syringe, carefully push up
piston until all air is excluded, then
by screwing the control trap down to
Il" this will guard against injecting
more than a dose at a time, then sue
cessively screw the control nut back,
dose by dose, until the ten calves are
vaccinated. For v~accinating, the calves
should always be run into a squeeze
chute Or cast. The injection is prefer
made in the tail, from six to eight
from the tip, always being careful
to push the needle in between the skin
and the loose tissue above the muscle
and bone of the tail. If you fail to get
into this loose tissue, it is often difficult
to inject the vaccine, but after a few are
vaccinated you will readily get the
knack, and can vaccinate four or five
hundred in a day, if necessary.
