84 THE MODERN MILK PROBLEM 



perhaps the most serious criticism to be made of the 

 score cards." 



The advocates of the score card believe that it can 

 be adjusted so that it may still be useful as a means 

 of dairy instruction, of guidance to the inspector or 

 demonstrator, of education of the dairy farmer, and 

 even of rating. An invaluable paper dealing with this 

 question has recently been published by Dr. North. 14 

 After discussing the compositions of well-known score 

 cards, Dr. North takes up the relations of different 

 items or factors to the actual character of milk as 

 shown by bacteria counts, concluding with a suggested 

 new type of card, in which 90 per cent of the score 

 relates to the three great considerations: milking, 

 cooling, and sterilizing. A division of items is also made 

 between primary and secondary equipment and pri- 

 mary and secondary methods. This suggested card is, 

 therefore, not merely a revision of present cards, but 

 represents a radical change in arrangement and em- 

 phasis. 



Dr. North's card, while not put forth as insusceptible 

 of possible modification, undoubtedly approximates in 

 its arithmetical degrees of emphasis the knowledge ex- 

 isting to-day on the relative weights of the various 

 sanitary items. It therefore affords a hopeful affirma- 

 tive answer to the question as to whether the score 

 card can be satisfactorily amended. Although con- 

 taining a large number of items relating to secondary 

 or non-essential matters, thus negativing the idea of 

 an exhaustive yet simple card, it will give both inspec- 

 tor and dairyman a very fair indication of the im- 

 portance to be attached to the various points in milk
