months and sometimes years before
any signs of i'll health are to be
seen. This slow development is the

perhaps large number are diseased.
If the disease developed rapidly and
caused death in few days, the own
err would soon take steps to check
its progress and protect the rest of
his herd, but on account of it's slow
and hidden course it is not noticed
until great damage is done.
The disease is not new one but
dates back hundreds Of years, al
though it was not until 1882 that
DR.. Robert Koch, a distinguished
German physician, discovered the
germ or seed" which causes tuber-
culosis. This organism is not ap-
parent under ordinary circumstances
to the naked eye, but it is living
organism and has to eat. SO to speak,
to live.
Now, to have tuberculosis you
must have the seed Of tuberculosis.
just the same as you must have the
seed of the peach tree to develop
peaches. You cannot have tubercu-
losis unless you have the specific
cause of tuberculosis. Now, remem-
Der that tuberculosis does not arise
from filth or dirt, or bad ventilation,
or unsanitary conditions of barn;
it cannot; it is impossible; you must
first have the seed of the disease.
Dirt, poor ventilation and unsanitary
conditions aid in its spread after it
has once been introduced into herd,
but these alone do not cause it.
Unfortunately the physical signs
or symptoms of tuberculosis in cattle
are not sufficiently certain to be re-
lied upon. 1t is true that animals do
have symptoms, but these are often
found in other diseases. Tubercu-
losis may attack any organ of the
body, so we may have varying
range in symptoms.
Some of the principal signs of the
disease are unthriftiness, loss OF
flesh, cough, enlarged glands, loss of
appetite, hard Jumps in the udder,
etc.
On post norton, when the carcass
of COW affected with the disease is
opened you will find tuberculosis or
Jumps in either one or several organs
of the body, such as the lungs or
liver. These Jumps may be so small
as to be scarcely noticeable, or they
may be as large as mans head. In
cutting one of these Jumps open you
will find it to contain a yellowish,
gritty substance or a cheesy, or soft,
creamy substance.
These nodules or Jumps are at first
very small, but as the disease be-
comes further advanced these become
larger and larger and often extend to
all parts of the body except the
muscles. or skin, which are seldom
affected.
Describes Tubercular Germs.
The germ or seed causing tu-
berculosis is a tiny, slender rod
shaped body which, as have stated,
cannot be seen with the naked eye.
Several thousand of them placed end
to end would be needed to measure
an inch. Once one of these germs
has gained Judgment inside the body
of an animal it begins to grow and
multiply. 1t becomes longer and
when grown divides crosswise, max
ing two out of one Each of these
goes through the same process, the
two become four, the four eight, etc.
This multiplication takes place
quite rapidly when conditions are
favorable Nature, however, does not

out offering some resistance. The
forces of the body are reused to ac-
ton and a battle begins between the
tissues of the body and the army of
the invaders.
The white cells Of the blood are
the bodies first defenders. These
rush to the seat of the trouble and
endeavor to destroy the invaders by
eating them up. If they are success
full the disease is checked; If not, the
disease still develops.
The second line of defense is
formed by the cells of tissues invaded
by the germs. These cells arrange
themselves in a circle around the
germs and try to form a living wall
between them and the rest OF the
body. This barrier gradually becomes
thicker and thicker and forms little
hard lump or tubercle. from which
