 understanding. 



You are inspectors, and I do not hesitate to speak plainly, 

 for I believe you will confirm every word thus far uttered, 



Now let us regard the details. 



Here is the milk producer, who may be a man of character, 

 intelligence, natural cleanliness and health ; he may be a man 

 unscrupulous, ignorant and prejudiced, naturally filthy and 

 indifferent to disease. Two extreme types with all grades 

 between are these, yet they are just what you meet. The 

 milk producer is the key to the situation, for he really pos- 

 sesses the power of making or unmaking a dairy regardless 

 of inspectors, cows, milk utensils, manipulation or handling. 

 Here, too, begins the bacteriology of the dairy, for in him is 

 to be found inexpensive intelligent direction or expensive 

 ignorant direction. Upon him the inspectors must rely for 

 their results and the city or town for pure milk. 



Owing to this almost complete dependence upon the milk 

 producer, and owing to the circumstances under which the 

 milk industry exists at all, it should be evident that the atti-

 ist in dairy matters from A to Z ; of an instructor and a silent, 

 tactful adviser. Do not inspect, but tactfully instruct and 

 advise. 



The cow must be a sound animal to yield wholesome milk. 

 Tuberculosis, with the light that is available, should be 

 stamped out, for it is a menace to mankind and to the herds 

 of the Commonwealth. Financially, it is for the interest of 

 the owner of the herd to eradicate this disease, otherwise he 

 will sooner or later pay the penalty in complete financial 

 loss ; hygienically, it threatens especially the infants of the 

 land. Every sound business or sanitary reason points to this 

 elimination, but of course immediate difficulties retard 

 progress. When every intelligent owner of cattle is prac- 

 tically in readiness, the way is blocked by professional and 

 other difficulties, lest horse and buggy be used in traveling the 

 path instead of an automobile. My experience has been that 

 it is not so much the desire of milk producers to prevent the
