62 A New Dairy Industry. 



milk is returned to the patrons, and as they are 

 capable, when properly managed, to disinfect the 

 skim milk at a trifling- cost from the pathogenic or 

 disease-producing bacteria that is, from those that 

 are apt to carry and spread infections diseases such as, 

 for instance, those of tuberculosis, typhus, foot and 

 mouth disease, scarlet fever, etc., they should be in 

 general use. In several European countries Ger- 

 many, for instance the creameries are obliged by law 

 to make use of them. When we refer, however, to 

 the object of this treatise : the manufacture of milk 

 into a healthy food for infants, it must be said that 

 the pasteurizing machine does not find an employ- 

 ment in this process because a higher standard of 

 efficiency must be aimed at, yet it seemed advisable 

 to explain the effects of pasteurization so as to be 

 able, later on, to define the difference between it and 

 sterilizing, and avoid the confusion that in the 

 minds of many now exists with reference to these 

 processes.
