HOG CHOLERA 339 



There seems to be little doubt but that any fanner or 

 breeder can protect his herd against loss from cholera by the 

 consistent and careful use of the protective serum and the 

 virus of the disease. It is a matter of some expense, and 

 the farmer must weigh the cost of the insurance against the 

 probable loss from cholera before deciding whether or not 

 to apply the treatment.
