l think from the above authoritative
quotation you may readily infer how
the hitherto careless handling of dis
eaSed carcdSSeS has increased our
areas of infection from year to year,
and especially with our particularly.
favorable conditions of moisture and
temperature, and many of our lands
subject to overflow and inundation,
which are also favorable for the re.
tention and development of CHARLTON
infection.
At the Experiment Station we have
fed charbon-infected material to the
dog, hog, cat, oppoSum, chicken and
common house.tiy, and have recovered
the organism in virulent form from
their bowel discharges; we have per.
mitted buzZards to feed upon the bodies
of small animals killed by feeding char.

germs from the feet, beak, and from
the VOmituS thrown up.
Technically, CHARLTON is spoken of as
"bacteraemia;" that is, the bacteria
are found in the blood, and it is in the
blood the rods multiply with such tire.

that comes in contact with Charlton
blood and can move from place to place
can carry the infection and create new
centerS of disease; and of course the
blood courses through all the tissues of
the body, and consequently the whole
carcass may be looked upon as infected.
And this leads up 10 the simple sanitary
fact, which, unfortunately, is not yet
sufficiently realized, that when an out.

Owing to infection being retained on
the surface of vegetation in sections
where the ground is fiat, cultivation
and drainage is part Of the treatment
of Charlton. In some parts of Europe
there are parts that have become so
permanently infected that they have
to be fenced off from live stock of any
kind.
The great difficulty in the control of
this disease is the many sources by
