Kentucky Agrtcnltnrctl Experiment Station. xvii
the General Assembly in 1910 appropriated to the Experiment
Station, the sum of two thousand dollars for the erection and
equipment of a small laboratory for the production and dis-
tribution of anti-hog cholera serum. The first output of
serum from this laboratory was made in April, 1911, and
from this time on, until quite recently, the demand for serum
has far exceeded the supply. Realizing the inadequacy of
this small laboratory and of our limited equipment for the
production of serum, further provision to this end was made
by the General Assembly in the State Act approved March
11, 1912, in which the increased production of hog cholera
serum and virus and the enlargement of the serum plant at
the Experiment Station Aiiere enumerated among the other
provisions of this Act. Accordingly, on September 17, 1912,
the Board of Control of the Experiment Station appropriated
out of the funds accruing under the State Act of 1912, the
sum of ten thousand dollars for the erection and equipment
of a new serum laboratory, and on November 18, 1912, com- .
petitive bids were received and opened for the construction
of a new laboratory and the contract for the erection thereof
was let to the Congleton Lumber Company, at a cost of
$10,640, thelaboratory to be completed by April 1, 1913.
Work on the new laboratory was begun at once and the work
actively prosecuted. Despite our inadequate equipment,
  ’ 1,036,435 cubic centimeters of serum were produced at the
Experiment Station during the year 1912. Four hundred and
fourteen herds of hogs, containing 19,656 hogs were inocu-
lated with serum furnished by the Experiment Station with
a saving of 91.2 per cent of all hogs treated with serum, and
within this period, the work of hog cholera vaccination was
A carriedt on in thirty—nine counties of the State. The map
