of the State to do this work. The farmer would, therefore, usually receive some 

 compensation for the cattle, althou<>h he would not obtain the value of sound cattle,, 

 those which had jreneral tuberculosis being, of course, a total loss. In this method, 

 I have embodied the main features of the methods adopted by the European countries 

 and have eliminated many of the pernicious features of some of the laws of our own 

 states which have been proved impracticable. 



Denmark adds two very important items by requiring that all milk passing through 

 a public dairy or cheese factory should l)e pasteurized to 85 degrees C. momentarily, 

 and that cows possessing tuberculous udders should be killed. The former checks the 

 spread of the disease through the feeding of tuberculous milk to calves, the latter 

 lessens the possibility of tuberculous milk. 



I believe much can be done by the milk consumers of the State in placing dairy 

 herds on a proper footing. The consumers, by paying a little more for the milk, may 

 demand tliat they have milk from tuberculin tested cows, or more generally speaking, 

 sound cows. But the milk consumers must not expect to increase the cost of producing 

 milk and impose that cost wholly upon the milk producer, for there is little enough 

 profit in the production of milk at the ordinary prices. If milk consumers cannot 

 pay more than five or six cents i)er quart, for milk delivered at their bouses in the 

 city, they themselves, by their own ponuriousness, invite infection. 



I wish to acknowledge the supervision of Prof. E. A. A. Grange in this work until 

 the fall of 1807, at which time he severed his connection with the College.
