Louis on Hog Cholera.

If any man knows more about hog
cholera than Theodore Louis, of the
Minnesota farm institute corps, he has
kept his light hid under a bushel. If
Mr.. Louis knows that, as yet, there
is no, specific. for this Devastating
plague, he knows the ounce of pre-
vention that is better than the pound
of cure, and, in reply to a questioner
in Hoard's Dairyman, he thus imparts
his knowledge:
AS to symptoms Of hog cholera, the
following are given by several of the
leading veterinarians that have given
the disease much attention and inves-
tigation: Dropping of the ears and
of the head; more or less coughing:
dull look of the eyes; staring appear
ance of the coat of the hair; partial
or total want of appetite for food; vi
tiated appetite for excrements; rapid
emaciation getting thin and lean);
great debility; weak and unsteady and
frequently staggering gait; great in
difference to surroundings, tending to
lie down in dark corners and to hide
the nose and even the whole head in
the bedding; a specific offensive smell
and a peculiar odor Of the excrements.
This last symptom Is always present,
at least in the advanced stages of the
disease, no matter whether constipa-
ton or diarrhoea is existing.
Among the characteristic symtoms.
which are not present in every animal,
may be mentioned frequent sneezing.
bleeding of the nose, swelling of eye
lids; accumulation of mucus in the in
ner corners Of the eyes; attempts to
vomit, or real vomiting; accelerated or
difficult breathing; humping or SPAS
modic contraction of the abdominal
muscles Cor f1anks), and a peculiar,
faint and hoarse voice in the last
stages of the disease.
The duration of the disease varies ac-
cord1ng to the violence and seat of at
tack and the age and condition of the
animal. When the attack is violent,
and It's principal seat is located in one
OF the vital organs-such as the heart
the disease frequently terminates fa-
tally tally IN q few days, but when the at
is not seriously affected, and the ami
mails are vigorous, from one to three
weeks may elapse before death ensues
From my personal experience there
is but little use to spend either time or
money to save them, for If saved they
don't amount to much anyway
DR.. Salmon says the disease can be
recognized by the following on post
mortem: The spleen, as rule, is very
black and enlarged; spots of blood from
the size of pins head to a quarter of
an inch or more will be seen in the fat
under the skin on the intestines, lungs,
heart and kidneys; the lymphatic
glands are purplish instead of a pale
pink. When the large intestines are
opened they are found covered with
these dark spots of blood more or less
uniformly and entirely: Often the con-
tents are covered with clotted blood.
Any or all of these may be considered
assigns of the disease in it's most viru-
In order to prevent the remaining
healthy animals in an infected herd
frem taking the disease the following
tance, some or all may be carried out
according to circumstances:
(a) Removal of still healthy animals
as far as possible from infected To-
(b) Destruction of all diseased ami
mails.
(c) Careful burying or burning of
cagcaSses.
of the infected premises.
(e) Great cleanliness both as to sur
roundlngs and as regards to food to
prevent its becoming infected.
Before removing animals from in
fected quarters, disinfect them by pour
ing. over them 2 per cent solution of
carbolic acid, and forcing them to walk
through such solution, but be sure
they are all healthy.
Among the various disinfectants
which can be recommended are the fol-
lowing: No. 1. Stacked or unslacked
lime, used both as powder and as
Stacked lime, containing about 5 to 10
per cent of dry lime Qrom one-half to
one pound of lime to gallon of water).
No 2. Crude carbolic acid, prepared by
adding to the crude carbo1ic acid OBJ
tainable from druggists at about 80
cents a gallon, an equal quantity of
ordinary sulphuric acid. This mixture
to be carefully added to Water in pro-
portion of ounces to l gallon of wa
ter, about 11a per cent volume No. 8.
A per cent solution (volume) of or
dinary sulphuric acid az ounces of
said acid to 1 gallon of water). No. 4.
A 2 per cent solution of pure carboIic
acid. This, is prepared by heating the
crystals slightly until they melt and
adding the resulting liquid to hot wa
ter in the proportion of IA ounces to
half gallon of water. "a pound Of
