Gus little scaritlcations. Into these
little cut places a portion OF warm
fluid lymph, taken from cow in the
advanced stages Of the production, is
poured, being gently and persistently
rubbed by the operator till he is sat
isfled all the lymph has been abb
sor0ed.
Then the animal is placed on an
elevated platform and made entirely
comfortable while the disease pro-
gre ,ses. The little cuts first seem to
heal over. Then in few days the
scabs grow larger and larger till they
extend almost over the entire hind
portion Of the leg. In seven days the
COW is ready for the next operation.
The affected part is darker and each
little point of scariflcation is swollen
and raised, like blister, with bit
of depression in the center
The blister is punctured or in some
cases removed. Underneath lies the
liquid serum or vaccine lymph, as it
is called. Then upon the ordinary
ivory points, which are now generally
used, the operator gathers his store.
He does it simply by dipping the
point in the spot OF serum before
him and laying them down in order on
tray which he holds in his lap as he
sits behind the animal.
The parts treated will continue to
secrete lymph for several days, when
the secretion comes more and more
slowly, dries up, and clogs the chan
uels through which it has flown, and
finally subsidies to scab. -Four or
five days later this is ready to be re-
moved. There is in it small guam
tity of real lymph, but there is more
of hair, membrane and other foreign
material. That gathered on the
ivory points is pure and contains no
other substance. But Of this latter
much vaccinating material is made.
After being thoroughly dried the
ivory points are put up in packages
of ten and are made proof against
either air or water They are then
ready for the market. The product
secured from the last day "scab" is
also prepared by pulverizing. 1T has
a certain strength and commands a
ready sale.
There are a good many ways to
make a point safe. 1T sometimes
happens that COW will not produce
active lymph. No matter how well
the blisters may appear they will not
yield virus that will prevent small
pox. No one can tell by looking at
a cow whether her product will prove
effective. 1t is like certain persons
upon whom no amount characterization
will @take.' To provide against any
loss on this account, points are dipped
often in the lymph of two COWS. 1t
is not likely two will be found stand
ing together neither of which Is good.
And these points are marked with a
double Y, and are sold at a higher
price. And still others are dipped in
the lymph Of three cows, marked with
three KS, and sold at still higher
price. They can hardly fail of effect
iveness. The ivory points are treated
chemically before being used, that no
disease extending qualities may lie In
ambush there.
One large COW has room enough for
a dozen scariflcations. In some cases
there are even more. And from each
blister a score of points may be load
ed. There is no bad effect so far as
the cow is concerned. She will never
De of any account as q producer of
lymph. or not one COW in a hundred
may be so used. But she will still
be as good mich COW as she ever
was. And even while she Is under
the treatment she seems to suffer but
little. She becomes feverish, just as
does the victim of vaccination. But
she mends In few days; and her
milk is always used again as soon as
she has been deprived Of all her serum
and is turned away from the stalls.
Vaccine points should always be fresh.
Their potency dies in a year to a
great extent
