herd since 1899 is $42.50. What change in the sys- 

 tem of feeding or caring for the herd would have re- 

 sulted in as large an increase in net profits? There 

 is no reason why the results secured from this herd 

 cannot be secured by the average farmer. It brings 

 us back again to the importance of using the scales 

 and Babcock test in determining the unprofitable 

 animals and then disposing of them as soon as dis- 

 covered.

SANITARY METHODS IN MILK PRODUC- 

 TION 



Cows. In order to produce clean milk, cows 

 must be carded daily and kept absolutely free from 

 loose hair and dirt. If the udder and flanks are 

 clipped this will assist very materially in keeping 

 the animals clean. For the safety of the milk, and 

 for the dairyman's profit as well, all cows should 

 be tuberculin tested once a year and reacting ani- 

 mals removed from the herd. No dairyman can af- 

 ford to keep diseased cows. Such diseases as garget 

 should be treated promptly, and if persistent, the 

 animals should be disposed of. These diseases con- 

 tribute pus cells to the milk and render it unfit for 

 consumption. Feed clean, healthy foods and such 

 as will not contribute an undesirable flavor to the 

 milk. The water supply for the cows should be 

 clean, fresh, and protected from possible contami- 

 nation.
