Mere than 324,0o hogs were immuniz-
ed for shipment as stockers and feeders
from stockyards of is cities during the
six months from July 10 December,
without spreading disease, in the face
OF all the attendant dangers required
OF course, such close care that the
wisdom OF some phases OF the inspec-
ton system may not have been always
apparent TO all concerned, A descrip-
ton OF the conditions uuuef which
stockers and feeder cattle arc inspect
ed is contained in a statement recently
issued by the bureau Of animal indus
try OF the department.

the statement. the pens of such YARDS
are inevitably infected with the CON-,
mon swine diseases. OF which cholera
is the most important, Owing TO this
condition Federal regulations formerly
required the slaughter OF swine receiv-
ed. but after the serum and virus
treatment against hog cholera was
standardized, the possibility of reship-
ping immature hogs for further feed
ing resulted In a modification of the

Purpose and Methods.

preyentive-serumt treatment. taking Of
temperatures and observing the con-
dition OF the animal during the test

il has come TO the attention OF the
department OF agriculture that in some
ca ses the rules have been misinterpret
ed so as TO make them appear respon
sible for fluctuations in the stock hog
market
For the information Of the public. the
Bureau Of Animal Industry outlines
briefly the method of Inspection:

Must Protect Purchasers.
The practice Of shipping swine from
one public stockyard to another before
immunization is liable to reduce the
protection afforded very considerably,
because Of the uncertainty as TO the
length Of time the animals have been
exposed. To permit the interstate
movement of such lots would afford
insufficient protection to the purchas-
ers who arc not familiar with these
various phases.
Department inspectors, therefore
have instructions not to supervise the
immunization of such lots unless it can
be shown conclusively that not more
than days have elapsed since the
animals were first unloaded in pub
lie stockyard.
The widespread interest Il the Feed
.er and stocker trade is shown by the
fact that the great ma jority Of feeder
hogs were sold in small lots. The fig
