War on Cattle Disease Goes
on With Increasing Vigor
in United States.

prepared by the United States Department
of Agriculture.)
The war against animal tuberculosis,
under the leadership of the United
States Department of Agriculture,
goes on with increasing vigor from
month to month. In order that the
countrywide situation may be clearly
understood, and that the various re-
gions may know just how much work
they have ahead Of them, the depart
ment recently prepared new "war'
map which shows the extent OF the
plague in all the states.
Show Progress Made.
On this map the shaded areas, vary
ing from solid black to pure white,
show what progress has been made
and how the different regions compare.
The scattered white spots indicate the
modified accredited areas, those coun-
ties in which the infection has been
reduced to O.5 per cent or less. In
the areas of deepest. shading the in
lection is more than 10 per cent. The
other areas have infection somewhere
between these two extremes.
The area with 0.5 per cent or less
of tuberculosis embraces q. 601 square
miles, or or per cent of the entire area
of the country. A large part Of the
United States, more than 100000
square miles, has less than one per
cent. This is practically SO per cent
Of the entire area, and accounts for
the recent statement by the depart
ment that 80, states promise to be free
of the disease within eight years. A
little more than Is per cent of the
country's area has from one to three
per cent of the cattle tuberculosis the
area being little less than $4,000
square miles. Herds in areas making
up 193,3O3 square miles, or 6.5 per
cent, have from to Z per cent of
tuberculosis.
The total area in which there are
herds with from to 10 per cent tu-
berculous cattle amounts to a little
more than $4,000 square miles, which
is 80 per cent of the total area. Only
2 per cent of the area, or 60,507
square miles, has more than Is per
cent of the heards infected with the
disease. The average per. cent of in
lection for the herds of the entire
country is 9.3.
These figures are the result of aver
ages obtained from the testing so far
done. The percentages apply to the
total cattle population which is esti-
mated to be 6S,927,613 head, but the
size of the cattle population in the
different areas is not in proportion to
the area. The large area of 100000
square miles in which there is less
than one per cent OF tuberculosis is
about SO per cent of the country, but
contains only little more than so per
cent Of the cattle. The area of great
est infection includes 49, per cent of
the cattle.
Many Cattle Tested.
During the month Of July, 478,291
cattle were tested in the United
States, Wisconsin leading with 69,615
head In 80 counties tuberculosis has
been reduced to 0.5 per cent or less,
the modified accredited areas There
are now in the country herds aggre-
eating more than 100000 cattle which
have been tested once and found free
of tuberculosis. Fully accredited herds
contain nearly 100000 cattle, and
more than 100000 cattle are under
supervision with view to being later
accredited. In addition there are more
than 100000 cattle in herds which
the owners have on the waiting list
for the first opportunity for testing.
