use of the tuberculin test as it is the inclination to avoid 

 the cost of professional testing, together with the possible 

 loss from the disease. When State aid is invoked, similar 

 loading up confronts the owners of cattle. Since the tuber- 

 culin test is acknowledged as the real diagnostic, can it not 

 be put to advantage in a reasonable manner, and the eradica- 

 tion proceed in a slow but persistent movement ? It has been 

 done in some localities of wide extent, and I believe can be 

 accomplished in a Commonwealth where the inhabitants are 

 very conservative and yet highly progressive. I cannot enter 

 into any detail, for this subject is sufficient unto itself. 



Mastitis is a much reported disease in these days because 

 of sore throats, scarlet fever and other unpleasant epidemics. 

 Of course, it should be recognized at once that there are differ- 

 ent forms of mastitis. Were it due to an inflamed and ulcer- 

 ated udder there is doubtless need of attention, but any one 

 who has passed an apprenticeship in milking realizes that in 

 a herd of eight or ten cows it is seldom some garget does not 

 appear in the mixed milk. Usually this is the result of some 

 local or general inflammation. Tests are now offered for the 

 detection of such difficulties. These tests are based on the 

 number of leucocytes or kind of leucocytes, the character of 

 the bacteria, upon the massing appearance or the formation 

 of some form of ferment. All or any one of these laboratory 

 tests should be used only as helpful diagnostics, to be inter- 

 preted in the light of actual findings in the stable. They 

 may be used as indicators, confirmers, and, in conjunction 

 with other tests and actual findings, become extremely useful 

 in reaching conclusions. 



It is unnecessary to speak further of the diseases of the 

 animal, — as to the possibility of anthrax, or the more remote 

 possibility at present of Malta fever, septic infections, cow 

 pox, milk sickness, foot and mouth disease and others. The 

 inspector should aim to know a cow as a breeder, the product 

 of his efforts, intimately, not as it is usually understood, but 

 intuitively. Training, skill, knowledge transformed into 

 intuition will accomplish much in recognizing the ailments 

 of milch animals. The true milk producer will possess this 

 insight in a greater degree because of his acquaintance with
