Bovine tuberculosis, which Is preva-
lent In every state and territory In the
United States to a greater or less de-
gree. Is the object Of concerted attack
by state and federal sanitary officials.
It is the most costly Of cattle diseases.

germs. tuberculosis was disseminated
from the eastern part OF the
United States into the middle west

means of imported cattle. and with
the development Of cattle raising IN
central and western states Its spread
was facilitated. In some localities In
the West where dairying has developed
extensively It Is now known that car
loads of cows. purchased in other
states, have contained 50 per cent or
more of tubercular animals. Some
herds Of beef cattle In the western
country have become contaminated
with the disease from tuberculons
purebred bulls and cows that came
from diseased herds elsewhere.
The tuberculous COW Is the greatest
source of danger to healthy cattle. Any
reacting cattle not promptly removed
from the herd constitute a constant
source Of infection. Tuberculous cattle
sooner or later begin to give on the
germs Of the disease These germs es-
cape by the mouth. nose and bowels.
and in milk. The discharged germs are
carried In the air for time until they
fall to the ground. Healthy animals
eat and thus contract the disease. Con-
tinuous water troughs In barns contain
ing diseased cattle. drinking holes con-
tanning material from infected animals
failure to clean and disinfect the
premises occupied by the diseased cat
tie, and infected milking tubes and the
practice Of feeding calves with raw
milk from tuberculous cows, are
means by which tuberculosis spreads
In a herd.
Sunlight Kills Germs.
tuberculosis Is caused by rod

powered microscope. When exposed

the germs Of tuberculosis to re intro

fore the disease can be produced, Their
are many conditions or accessor
causes which make animals especial
susceptible to tuberculosis. Stablin
animals in dark, poorly ventilated an
dirty barns helps to spread tubercult
sis among the stock whenever tn
germs are present. Any condition tina
