even though trained veterinarians were available in sufficient num¬ 
bers to do the work. Every live-stock owner should be a party to 
this campaign which has been inaugurated to eradicate tubercu¬ 
losis. In almost every locality of the United States are veteri¬ 
narians capable of rendering valuable services to live-stock owners in 
this great work, and the cost of eradicating is greatly reduced by 
combating the disease in its early stages. Yet even in badly af¬ 
fected herds eradication can be undertaken with success. There 
are records of many herds, in which three-fourths of the animals

is positively due to the consumption of infected milk or other dairy 
products from tuberculous cows. It is eminently proper for the 
respective State governments to expend funds for the maintenance 
of tuberculosis sanitariums for the care of persons afflicted with 
that disease, and likewise it is extremely important to use vigorous 
measures to check the marketing of germ-laden milk. While it is 
true that proper pasteurization of milk destroys the living organisms
