each calf two doses OF highly attonu"
ated blackleg virus, with an interval OF
ten days between the inoculations. The
first incubation Is made with very
mild vaccine, the so-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 a hypodermie
sy4 nge 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, 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 OF
incubation. Kits method has been
adopted to a very large extent In east
ern Europe and northern Africa with
very satisfactory results, and 1t mas
for that reason and on account OF lts
simplicity, been taken as the founda-
ton for the Investigations made by TINS
bureau. A Single vaccine" has been
prepared 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.
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 Du'
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-
atlons. Persons lacking the necessary
outfit to test the vaccine should procure
one If they propose to test the vaccine.
It consists of a graduated c. C. syringe
with detachable needles, small por-
celain mortar and pestle, 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?
2. What experience have you had in
yaccinating calves against blackleg?
8. How many head do you wish to
yaccinate 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
LEGATION is followed.
