HOW SOLVE THE PROBLEM? 161

In forming plans for the expenditure of the annual ap- 

 propriation for milk control the milk dealer as well as the 

 health officer should bear in mind that one laboratory worker 

 can test the milk of fifty dairy farms for bacteria while one 

 dairy inspector is inspecting five dairy farms, and that there- 

 fore one dollar spent in laboratory testing covers as much 

 territory as ten dollars spent in dairy inspection. The labora- 

 tory test should come first and make the diagnosis; the dairy 

 inspector should come second and apply the remedy. These 

 principles result in the greatest economy and efficiency, 

 whether control is being exercised by the milk dealer or by 

 the health officer. 2 



THE ROLE OF INSPECTION 



Inspection seems to have been originally regarded 

 as a species of policing, often with the elements of de- 

 tective work. The object was to " catch" the bad 

 milkman. This idea has now been largely superseded 

 by that of advice, of " education of the dairyman." 



Dairy Demonstration 



The conclusion toward which modern milk control 

 is tending is this: if the product, the milk itself, is to 

 be judged, rather than the dairy, and the dairyman 

 understands that its resultant bacterial character is 

 the all-important thing, then he will welcome advice 

 which will help him to produce better milk. If he be 

 held responsible and be paid for good results, he will 

 practice the methods for getting them.* And if those
