EIGHTH ANNUAL YEAR BOOK— PART V. 225 



this disease exists in animals. The tuberculin test will g:ive as 

 strong a reaction in animals having minute particles of the disease 

 as in the animals that are in an advanced stage of the disease. So 

 there is no means of determining the stage of the disease in animals. 

 The condition of the animal with reference to tuberculosis can only 

 be determined, in the majority of cases at least, by post-mortem 

 examination. So I do not think our stock breeders would stand 

 for a system of putting the tuberculin test and condemning all the 

 animals that react. I do not believe it would be a good policy to 

 advocate ; but I believe we will have to approach it by more rational 

 and conservative methods. If the government in.spection can be 

 extended so as to be established through practically all of the 

 packing houses, the smaller as well as the larger, it would in the 

 first place insure wholesome and sound meat in the market. In 

 addition to this, if we had that system it would enable the disease 

 to be traced back to the farm where it originated and enable the 

 stock to be sold subject to post-mortem examination. It seems to 

 me that this is the most feasible plan of solution of this problem. 

 If we can arrive at a system which will enable the disease to be 

 traced back to the farm it would be very easy of solution, because 

 the burden then falls on the man whose herd has the disease and it 

 is to his interests to eradicate the disease. I believe pressure along 

 this line, as well as along the other lines suggested, viz., not bringing 

 the animals into the state without subjecting them to the test, and 

 the test of dairy herds supplying milk to the public, would go a 

 good way toward solving this ciuestion. I think, also, the legisla- 

 tion concerning Pasteurization of skim milk should be made to 

 cover buttermilk. 



Mr. Wright : It may be of interest to know that the law with 

 regard to the Pasteurization of milk will not reach many of the 

 farmers, for the reason that from six to seven tenths of the butter is 

 made from cream that is skimmed on the farm and the skim milk 

 never leaves the farm, so is not Pasteurized. 



Mr. Curtiss: There is this feature to that situation — it does 

 not permit the disease to extend beyond that farm. 



Mr. Wright : So that the Pasteurization of milk is not universal 

 in the state. There is another feature that appeals to me particu- 

 larly, and that is that there seems to be a very great interest on 

 the part of the people of the state who buy milk in the city in rela- 

 tion to the health of the cows producing that milk. The number 

 of inquiries that we have is doubling and trebling every year, and
