VACCINE YARIOLA-COw POX.

VACCINE YARI0LA-COW POA.
Henry Stewart writes to the Rural
NeJC Yorker. One of tine most annoying
diseases to which cows are subject. is
pOx. or yariOla. 1t would be- tIlfng in
its effect upon the COW were ii not that
il affects the teats and renders milking
difficult. or almost impossible: and tina t
when it appears in a herd it goes thro'
the whole of it. The disease is an erup-
tive, contagious fever, communicated by
a special virus reproduced 10y the disease.
The history OF the disease is as follows
When the owner of q cow is mIlkIh g
the animal. he discovers that she IS uu-
easy and restless. and on searching tor
the cause may lind one or more hard no
duIes in the skin of the teat, which are
Dainful TO the COW when pressed. The
milk also falls off somewhat in quantity.
In a few days these nOdules appear at
the surface in the form of round in
famed spots on the teats, somewhat
raised above the skin. and depressed or
pitted in the center. In three or four
days the spots are found to contain liquid
matter, and, il care IS not taken, are
broken and may become raw sores which
are difficult to heal, which. in fact, some
times result very disastIOusly Cnd even
fatally.
By-and-by the contained liquid be-
comes q thick, yellOwish pUs which dries
into q scab, and this in time becomes
loose and falls off, being replaced by
newly-fOrmed skin. When one case is
out of the way another appears, and in
herd OF twenty OF more it may continue
the whole summer in its passage through
the herd. giving constant annoyance.
During the progress of The disease the
udder is iuhamed and tender, and the
teats are quite painful when pressed so
much so that milking in the usual man
ner is impossible. Recourse is then had
to milking tubes which are made of sill
yer and carefully inserted Iuto the teaU,
being fabricated with lard or sweet oil
to prevent irritation of the lining mem
bIane OF the organ. The milk flows
through the tube and the uddeT is easily
drained dry without any Inconvenience
to the animal.
The disease is readily communicated
to mankind and to horses, and spreads
from cow TO cow being usually convey
ed by the mixer whose hands and cIO-
thing soon become infected with the
virus. The matter contained in the YER
siCles is the true vaccine virus used for
inOCulatiug persons as an antidOte to the
more dreaded and ViTUleut smallpox,
and in its effects upou mankind occa-
siOus no worse disturbance than the
slight fever, and sometimes glandular
swe.liugs incident TO the operation of
vaccination. The virus viii often re-

The treatment Of The disease is very
simple, u precautions are used to pre-
vent The rupture or forcihie removal of
the yasiClas III seahs before the contain
ed matter has dried and hardened. This
IS best done bv lIe use of the milking
tubes and by s0iLeuiur the teats aud al
laying the irritation by cooling, em0lieut
applications, such AS the simple Cerate
of the druggist or the prepared cOsmO-
line or yaselIne jelly which is both emo
lieut and antlsep.iC. being a preparation
from petroleum. The only medicine
required is a daily dose of one ounce of
hypOsulphate of soda in the feed, given
as long as the eruption lasts. The same
may be given TO the other cows or hCif-
er5 in the dairy or stables as a pTeveuta-
tive or as a means of very much tighten
ing the results of an attack upon them
During the continuance of the disease
the effect upon the milk is either impeT-
Ceptible or very light. When at the first
outset the udder becomes hard and in
famed, the milk curdIes prcmaturCiy
and viii often thiCken if brought to a
heat of $50 degrees There will some
times be white specks in the butter
caused by the cOagulatiOu of portions OF
the milk. and perhaps by the presence of
secret matter in it &; but in general there
is nothing in the milk that would indi-
cate that the COW was ailing in any way
Nevertheless, as the disease is a blood
disease and the blood has been subjected
to the action of q special virus by which
the disease has been produced, and as
the milk is a direct product from the
blood it Is at least subject to suspicion
and should not be used by persons who
are particular as TO the purity and whole
some character of their food, which they
are wise ia demanding should be above
suspicion.
The duration Of the disese is from ten
10 twenty days, and if the cow is kept
warm and free from exposure Co rain ana
inclement weather, no complication is
likely TO occur. In some cases the dis
ease passes of with q very slight erurr-
