treatment:
The experiment station has published
several short articles giving in brief
way the general OF bIackIeg and describ-
ing the best means % preventing the
disease, as well as advising such sani-
! tary precautions as seem best TO FOL
low under the circumstances. The re-
suit is the very general practice OF vac
cination, stockmen generally recognizing
| that fact that blackIeg can be prevented
in this way.
All Of the work in connection with the
distrbution of the vaccine has been
kept in he form Of records which VIII
be of value as the work progresses. Much
of the laboratory work has been done
by Mr.. f J.. Rector. an assistant in the
veterinary department. Those who use
the vaccine can very materially add 10
the general information OF the subject
by reporting any unusal occurrence no
ticed in connection with the use Of the
vaccine.
SYMPTOMS.
The symptoms OF blaclleg are so char
acteristic that there need be no mistake
made in recognizing the disease. The
general symptoms are loss Of appetite.
dullness and high fever. followed by
suspension OF rumination and general de-
preston. They are not essentially diff
ferent from the symptoms OF any other
acute Infectious disease. Within a very
short time after the first symptoms are
noticed there appears a swelling or tu-
NOR on some portion OF the body. These
tumors may occasionally be noticed as
the first symptom of the disease. the
animal still having a good appetite. look
ing bright, but lame from the effect of
swelling. The swelling or tuInor is the
most important feature OF the disease
and is always associated with lameness
when the swelling is on any part OF the
fore or hind leg. These swellings may be
seen on any portion OF the body except
that part of the limbs below the knee
or hook or on the tail. The most COM
mon location is on the thigh or shoulder.
These tumors are at first hot ana painful
but spread rapidly and soon become
filed with gas, as can be determined
by passing the hand over the swelling

tumors frequently increase rapidly in
size and may cover a large part OF the
body in few hours. After the gas be-
gins to form the tumor is not sensitive

PREVENTION.
It is well to. state at the outset that
there is no curative treatment for black
leg. There are occasional cases OF the
disease that will recover. but the aver
age case Of blackleg no favorable re-
suits can be expected from any medical
treatment In those cases that do re
cover the animal IS immune 20 subse-
cuent attacks. Al the various methods
adopted as a means Of prevention may
be placed under such sasitary measures
