INCIPIENT TUBERCULOSIS 153 



ily cow will continue to be written until all communi- 

 ties provide rigid rules and regulations to govern the 

 production and sale, and. even the use, of milk. Every 

 person who keeps a cow for milk should be com- 

 pelled by law to submit the animal to the tuberculin 

 test at least once every year. Once every six months 

 would be even better. Under present conditions the 

 veterinarian's attention is called to these cases only 

 when the cow is actually sick, and more likely than 

 not has been feeding the family with virulent milk 

 for months past.
