76 THE MODERN MILK PROBLEM 



factors which are thought to affect the quality of milk 

 in any way have been carefully studied and the in- 

 fluence of each determined and accurately measured. 

 In this way the really important factors can be singled 

 out and given the proper value on the score card." 



What these important factors are will be considered 

 in the following section, after which the question of the 

 feasibility of amending the score card will be taken up 

 again. 



RATIONAL METHODS IN CLEAN MILK. 

 PRODUCTION 



The impression which has long been growing upon 

 acute observers, that the production of clean milk is 

 not the complicated matter that it has been supposed 

 to be, is now scientifically confirmed. For a number 

 of years some highly significant experiments have been 

 carried on by Harding and others 9 * at the New York 

 State Agricultural Experiment Station on the proposi- 

 tion that " there is great opportunity for economy in 

 sanitary milk production through the saving of useless 

 labor. " These experiments, conducted with reference 

 to single dairy conditions and operations, show that 

 certain of these, commonly thought influential, really 

 exert little or no influence on the germ content of the 

 milk. Following are some remarks from this study 

 (italics inserted) : 



* In actuality these experiments were antedated by those of Dr. 

 North which resulted in his system described below (cf. Appendix C), 

 but it seems logical to introduce them at this point on account of the 

 general nature of the ideas brought out by them.
