 This salvaire has reduced to a marked extent the cost of the 

 eradication of tuberculosis. 



The basis for the compensation of stockmen by the State 

 is the sanitary importance of the disease, and the mve^ity 

 of safeguarding the public welfare as well as the economic 

 relations. In determinini! this amount, the proportion paid

Vaccination. .Many attempts have been made to use vac-
