bureau with q view of devislng some
measure through which the steadily in
creasing losses might be arrested or re-
duced as much as possible. In Europe
where this disease has long prevailed
the animal losses in certain badly IN
tected districts, became so disastrous
cattle raising had to be abandoned
About fifteen years ago three French
scientists, Arloing, CoTnevtn ana
Thomas. succeeding in producing vac
cine against blackleg, which is now eX-
tensively used in many countries WneIe
the disease prevails to serious extent
The method consists in injecting INTO
each calf two doses of highly attenu-
ated blackleg virus, with an lnteT'aI VI
ten days between the NEGOTIATIONS Inc
first incubation is made with very
mild vaccine, the sO-called nrsI
lymph" and the second one with the
stronger virus, the second lymph
and in each case the vaccine is lntFo-
duced by means of a hypodermlc
syringe under the skin of the lower
part of the tail. This method, which
is very inconvenient, especially where
large number Of animals are 10 De
treated, was later modified by Ger
man scientist, Kilt, who reduced the
process to a single injection with less
attenuated virus, and who chose the
loose skin on the side of the chest just
behind the shoulder, for the point Vi
incubation. kits method has been
adopted to a very large extent in east
Africa
very satisfactory results, and II mas
for that reason and on account OF us
simplicity, been taken as the tounda-
ton for the Investigations made by tnls
bureau. A single vaccine" has Deen
prepared in the pathological laboratory
and subsequently tested on large
number of calves in Texas, both COM
mon and high grade stock, and the re-
suits warrant the conclusion that this
vaccine is in every way satisfactory.
1t is desired, however, before distrib-
uting this vaccine to stock owners in
general to obtain record of several
thousand successful vaccinations. For
this purpose a quantity of vaccine will
be distributed to such parties as may
desire to make preliminary Vaccina-
lions and report the result to this bu-
reau. Those stock owners will be pre-
ferred who already have experience in
vaccinating stock for blackleg and are
in possession Of a vaccinating outfit.
Explicit instructions will, however, be
sent with the vaccine to secure uni
formity of operation and to assist those
without previous experience in vaccin-
atoms. Persons lacking the necessary
outfit to test the vaccine should procure
one if they propose to test the vaccine.
1t consists of graduated C. C. syringe
with detachable needles, small por-
celain mortar and pestle, a glass fun
mel and some filters This outfit can
not be supplied by the department, but
must be purchased of some house which
supplies such articles.+
Upon applying for vaccine please an
sWer the following questions:
l. To what extent does blackleg pre-
vail in your part of the country and
/ how great is your animal loss from this
disease? .
q. What experience have you had in
vaccinating calves against blackleg?
8. How many head do you wish to
vaccinate and what class of cattle are
they, common, graded or full blood?
4. What is your express Office
"The outfit is prepared in accordance
with the plans of this bureau to meet
the temporary demand that may arise
in introducing this vaccine. If vacci-
nation should be extensively adopted
as a preventive of this disease similar
outfits will, no doubt, be for sale by
other dealers furnishing this class Of
supplies. Until this may be the case,
the unusual course of mentioning a
dealer by name in department pub
lication is followed.
