bureau with a view of devising 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
fected districts became so disastrous
cattle raising had TO be abandoned.
About fifteen years ago three French
scientists, Arloing, Cornevin and
! Thomas. succeeding in producing vac
cine against blackleg, which is now ex-
| tenslyely used in many countries where
/ the disease prevails TO a serious extent.
! The method consists IN injecting into
each calf two doses of highly attenu-
ated blackleg virus. with an interval OF
ten days between the NEGOTIATIONS. The
first incubation Is made with very
mild vaccine, the 8O-called FIRST
lymph" and the second one with the
stronger virus, the second lymph,
and in each case the vaccine is intro
duced by means OF hypodermic
syringe under the skin of the lower
part Of the tail This method. which
Is very inconvenient, especially where
large number OF animals are to be
treated, was later modified by Ger
man scientist. Kit. 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 OF
incubation kits method has been
adopted to a very large extent in east
crn Europe and northern Africa with
very satisfactory results. and it has,
for that reason and on account of its
simplicity. been taken as the founda-
ton for the Investigations made by this
bureau A Single vaccine" has been
In the pathological laboratory
and subsequently tested on a 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. !
II is desired, however. before distrib- |
uting this vaccine to stock owners in |
general to obtain a 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 yaccina-
tons and report the result to this bu-
reau. Those stock owners will be pre-
ferred who already have experience in
vacclnating 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 II they propose to test the vaccine.
1t consists OF a graduated c. C. syringe
with detachable needles. a small por-
,elain mortar and pestle, glass fun
lel and some filters. This outfit can
rot be supplied by the department, but
must be purchased of some house which
supplies such articles
