might be afforded in case any immunity could be assured. It 
should be remembered, however, that in case there should be 
considerable losses from inoculation, this would be more se¬ 
verely felt with high-priced animals than with those of aver¬ 
age value. Another consideration even more important ap¬ 
pears to have been overlooked. In inoculating a herd the 
contagion of the disease is introduced upon the premises, and 
in spite of any precautions which can be observed the grounds 
will be infected. This infection remains a considerable time, 
and the experience of those who have had herds inoculated is 
said to show that if any uninoculated hogs are added to the 
herd they are very liable to contract cholera and succumb to 
the disease. If this observation is correctly interpreted, it is 
apparent that hogs sold from such herds for breeding pur¬ 
poses are liable to convey the disease to the herds into which 
they are introduced. This being the case, no breeder could 
afford to have inoculation practiced on his herd, because none 
would buy from him knowing that there was danger of in¬ 
troducing a fatal disease with the animals purchased. 
The considerations mentioned above, which our present 
information demonstrates to have a bearing upon the subject 
of inoculation, should be taken into account by Swine breeders 
before the adoption of this operation. There are undoubtedly 
other arguments for and against inoculation which greater 
experience will bring out, but we can only form a reliable 
opinion of its availability by reasoning from the knowledge at 
hand, and this we have endeavored to set forth with as much 
detail as is practicable in a report of this character.
