CONTROL OF HOG CHOLERA. 17 
ply a force of 50 or 60 skilled men for field service at an annual cost, 
at the beginning, of about $200,000. This would enable the Federal 
Government to place 3 men in each of about 20 States. The States at 
the same time should supply for education and organization at least 
as many men as the Federal Government, and double the number 
would perhaps better fit the needs of the case. On the basis of an 
equal number, each State would need an appropriation of $10,000 
annually for this work, and an equal sum should be available for the 
use of the State veterinarian in the campaign for improved sanita- 
tion. The cost of the needed serum should of course be borne by the 
farmers themselves. 
This is a very modest program for dealing with a disease which 
annually causes losses amounting to many millions of dollars. How- 
ever, it is believed best to proceed slowly and surely and in such a way 
that the farmers may be encouraged to do the greater part of the work 
themselves. 
This discussion should not be closed without laying emphasis upon 
the importance of further research on the cause, modes of dissemina- 
tion, and methods of preventing hog cholera. While complete eradi- 
cation does not seem feasible at the present time, it is entirely possi- 
ble that further research may enable us to discover means whereby 
complete elimination of the disease may be eventually realized. This, 
of course, is the end for which all concerned should continually strive. 
Both Federal and State Governments should provide for research 
along the lines indicated. 
SUMMARY. 
1. No feasible plan has yet been devised for the complete eradica- 
tion of hog cholera, yet it is entirely possible to control the losses 
from the disease and thus place hog raising upon a relatively stable 
basis, freed for the most part from the cholera menace which has been 
for so many years the bugbear of swine growers. 
2. The plan of slaughter of infected herds with strict quarantine 
and disinfection of premises, such as has been pursued successfully 
in combating foot-and-mouth disease, is entirely unsuitable for the 
control or eradication of hog cholera in the United States. 
3. A campaign of education with the prompt and intelligent use of 
serum 1 increases the interest and confidence of farmers in hog raising 
and results in reduction of losses and greatly increased hog pro- 
duction. 
1 The methods of administering serum are described in Farmers' Bulletin 834, " Hog 
Cholera : Prevention and Treatment," to which the reader is referred for a discussion of 
the "simultaneous" and "serum-alone" methods of treatment.
