based upon the supposition that each hyper-immunized immune will fur- 
nish one hundred fifty to two hundred doses of serum and that the car- 
casses of the immune after final bleeding will be used for food, which 
would stand to reason, that the serum station should be located near some 
packing house center. There seems to be no objection to the use of 
such carcasses for food purposes, providing the post mortem examination. 
by a government inspector discloses no reason for rejecting it. 
The serum station should be under the control of the State Veterinary 
Department, as it is to the veterinary that the farmer applies when he has 
sickness in his herd. It is the veterinary who must hold post mortem 
to positively .diagnose the disease, it is also the veterinarian who ad- 
ministers the treatment and places the affected herd in quarantine. 
The expense for the setablishment of such a station would be very small 
as compared to the loss sustained annually from this disease. A tract of 
land could be leased for a term of years, rough grazing land could be 
rented at a nominal sum and would answer the purpose as well as expen- 
sive land. A building for preparing the serum need not be an elaborate 
affair. Temporary sheds could be constructed for the housing of hogs in 
winter time. 
The field application of serum should be in the hands of the State Vete- 
rinary Department. The state could be organized into districts, each in 
charge of an assistant State Veterinarian who should have a supply of 
serum on hand so that prompt action may be taken v/hen an infection 
appears. 
Upon notification to the State Veterinarian that hog cholera has ap- 
peared in a certain locality the diseased herd or herds should be immed- 
iately quarantined and all hogs on the farm which have been exposed or 
which are not visibly ill should be treated with serum alone. All hogs on 
the farm which have not been exposed should be treated by the serum 
simultaneous method, and of course the prompt removal of dead animals 
should be enforced, at the same time all the hogs on surrounding farms 
should be treated by the serum simultaneous method.. 
After the establishment of a serum station by the state, it could in a 
short time be made self-sustaining by selling the serum to the farmers 
at actual cost of production and the farmers could vaccinate their ho^s 
when they are from two weeks to eight weeks old, they could do it at a 
very small expense. A pig weighing twenty-five pounds only requires 
about 5 c. c, at the price that Michigan is selling it to its farmers it would 
only cost ten cents per hog. 
It appears to me that if this corn belt meat producing association would 
ask for an appropriation of sufficient sum to establish a hog cholera sta- 
tion, it could not be turned down by that body. 
Question : What is the difference between swine plague and hog 
cholera 1 
Dr. Boughman: There is a difference of opinion as to whether 
there is a distinction or not. There was a time when they thought 
they had found the specific germs for each disease. Dr. Niles tells 
me that this serum will act as well on one as on the other.
