of 45 degrees, that the surface of milk pre- 

 sented to falling dirt may be reduced. 



In case of any pollution by the cow during 

 milking the milker should be careful that 

 no drops of urine, bits of feces, or dust raised 

 by the droppings get into the milk, and if a 

 pail of milk is contaminated in this way, or 

 by another accident, such as a cow putting 

 a hoof into the pail, the milk should be kept 

 from the general supply. 



As the milking must be done expeditiously 

 it is necessary and also a wise provision that 

 all unnecessary persons be excluded from 

 the cow barn. They not only disturb the 

 herd, and, therefore, affect the flow of milk, 

 but they also represent an unknown danger 

 of infection. 



Children under fourteen years of age 

 especially should be excluded, as they may 

 be carriers of diphtheria or scarlet fever, to 

 which they are more susceptible than adults. 



Small animals, such as dogs and cats, 

 should not be permitted in barns and dairy 

 rooms.
