INFECTIOUS pIsuRe. PNEUMONIA.

Although there are no evidences Of
this dread disease among the cattle Of
the plains, the LEADER presents = few
facts concerning it which are Of inter
est to all cattle men. We may say
here that although the disease is not in
digenous to this section, the malady may
be imported. This need cause no
alarm, however, as affected cattle, by
reason of a change of food as well as a
change of climate, would soon recover,
while the contagion would neither be
widespread nor serious.
Pleuro-pneumonia Isl specific, highly
contagious disease Of the respiratory
organs, peculiar to cattle. 1t was first
brought to the United States in 1913,
appearing in Brooklyn, N. Y; it was
brought to the same city again in 80;
New Jersey was afflicted also in Al.
In each case English cattle brought the
disease to this country. Digressively
we may remark that the English gov
eminent should be somewhat charitable
in dealing with American cattle for the
foregoing reason.
Ever since 1913 there have been al
most constantly cases of the disease in
the vicinity of New York, where it is
known as the swill-milk disease. Dis
tillery fed cattle have always been
quick to catch the complaint, and in
deed, in some states there we're always
poor brutes suffering from the affec-
ton.
As the disease has a period of incu-
baton, varying from two to about six
weeks, its insidious nature is apparent.
Hence the ease with which it may he
spread. From the contraction to the
development of the disease an improve
ment in the appearance and condition
of the animal is noticed, while in the
case of milk cows an increased yield is
frequently found. At this time the
animal may be transported with healthy
cattle, and some time must elapse be-
fore the fact is discovered that the
whole number contracted the affection.
In this way the disease spreads rapidly
and in an alarming manner
At first it is difficult to detect the
malady, especially to an inexperienced
person. The temperature of the ami
NAL rises at least four degrees. Ac-
companying this are a slight loss of APP
petite, disturbed respiration, faint, un-
usual sounds in the bronchial tubes,
slightly accelerated pulse, often an oc-
casional shivering at, frequently a
slight, hard, dry cough, especially after
drinking, and a disposition to keep
away from the rest of the herd. The
second stage begins with an increase in
temperature of four more degrees.
Thus, if the temperature of the animal
when healthy was about 100 degrees, in
the second stage 1t would be 108 de-
grees, or even MORE. The flow of milk
rapidly decreases; the mouth is hot;
the breath noisome; the breathing
rapid and labored, while a low grunt
evinces pain at each respiration, as.
with unstretched neck, the suffering
beast tries to breathe more freely. The
bowels are constipated; the urine scanty
and high colored; the cough frequent,
