pressure produced by the introduc~
ton of such great quantities of blood
under ths skin causing assesses.
The second way is the slow sub
cutaneous method which has less radi-
cal effect on the hog, and is less likely
to cause assesses. 1t takes a longer
time to produce a hyperimmune than
the first way. Administer doses of
one, two and one-half and five cubic
centimeters per pound of body weight
seven to ten days apart, thus giving
the immune ample time to recover
from the transitory effect produced.
The third way is known rs the
abdominal method introducing the
virulent blood directly into the peri
toneal cavity. The dose is the same
as in the first way. Care must be
taken not to puncture the bladder.
This method is best employed by
suspending the animal by the hind
legs and allowing the abdominal coz
tents to rest on the diaphragm, Thea
inserting the needle through the wall
of the abdomen about two or three
inches below the anterior borders of
the pubs, an inch or two inside OF
the median line to avoid puncturiDg
Of the bladder.
The fourth way by intravenoug in
lection. Virulent blood is introduced
directly into the circulation by way Of
the ear-vein at one dose. Five cubic
centimeters per pound are prescribed
1t is difficult to reach the veins, be-
cause of the coarse ears, and often
the veins are scarcely visible. How.
ever, this method is trifle more
potent A $50 pound hog requires 750
cubic centimeters of serum.
How the Serum Is Obtained.
The hog is placed ON the table and
then washed, the tail is thoroughly
washed with an antiseptic solution
and luke-warm water and soap, ans
then with weak solution OF alcohe

sterilized. A piece of the tail is amYu-
tated, and in this way the blood is
drawn from the hog.
From q hog weighing $50 pound;
about three pints of serum is obtaineG
at one bleeding. A hog can be blei
four times before he has to be hypef-
immunized again. The blood received
in this way is defibrinated, and the
small amount Of carbolic acid is added
to preserve it, and does not injure It's
protecting power. The blood is then
ready for use.
A hog weighing $50 pounds will
yield from 80 to 100 doses OF vaccine
at one bleeding. A hog can be bled
once every eight or ten days. The
above are government directions.
After the serum has been tested
and found to be potent. it is put up
in bottles of three sizes, sealed ana
stored in a cement cellar, where it
can be kept at even temperature
until used. =.
Some Dangers to Be Avoided.
From the fact that there is always
more or less fever caused by VAGINA
ton, and more or less danger Of the
animal becoming infected through the
wound made by the needle OF the
syringe, the following after treatment
is recommended:
Spare diet for three or four days,
Of corn, but plenty of wa
ter, thoroughly clean and comfort
able pens with plenty Of clean bed
ding, with absolutely no chance to get
into the mud Of any kind. The more
mud and dirt the more danger. They
should not be dipped or operated upOr
for at least two weeks after vaccina-
ton.
When the disease makes it's appear
ance in the neighborhood, all the well
hogs should be vaccinated, and all the
sick hogs should be destroyed and
burned, and should any of the vac
cinated hogs develop cholera, they
too, should be destroyed and burned.
This will prevent to certain extent
the spread of infection. Among the
most convenient and efficient agents
for destroying disease-germS rank
heat, solution of creolin, carbolic acid,
caustic soda or Sulphate OF copper.
fumes of chlorine, chloride of lime,
Stake lime, lime water and kerosene
oil.
All straw, cobs and litter should be
removed, and If cholera is present,
burned, and 2 strong solution Of some

and floor of the pen.
Though hog-cholera is not commuzi-
cable to man, there is danger 81 an
thrax, septic infection and tubercu-
losis. If a person has sore on his
hand he should not touch a dead ami
nal, or If he should receive cut "a
