THIRTY-SEVENTH ANNUAL CONVENTION. 177 



employer and showed him that some of the healthiest of the 

 herd were affected the farmer said : "Those are my very best 

 animals; they are perfectly healthy." The farmer further said: 

 "It is useless for you to say anything more, I will not dispose of 

 those animals." 



What did this man do? The matter ran along for three or 

 four years. Some of the animals began to grow thin and not 

 do well ; their milk flow began to fall off. This condition prog- 

 ressed rapidly until some of these animals were nothing but 

 skin and bone. They caughed almost incessantly and were 

 finally put out in the back pasture, and the farmer said : "We 

 will shoot those animals and get them out of the road." One 

 of those animals was opened up and in the lungs were found 

 the visible signs. Then he finally called in the city veterinary 

 to make an examination of the herd. This examination was 

 made four or five years after this first examination. In the 

 meantime his herd had grown and he had between fifty and sixty 

 reacters. That is the story which any man can experience. This 

 is only one of many cases where a man deliberately shuts his 

 eyes and says there is nothing in this question of tuberculin 

 testing. 



You have only got to follow that policy and that same kind 

 of a story will be told. The only way you can know is by the 

 application of this tuberculin test. If you have it in your herd 

 that is the kind of a history you will have. That comes through 

 the purchase of an animal affected in the earlier stages. 



If you take that milk to a creamery, or if you are shipping 

 that milk into Chicago or if it is going the length of this state 

 this problem does obtain, the question is what kind of skim milk 

 do you return. It is the milk of all the animals that contribute 

 to that creamery. Suppose there are a few herds that have 

 gotten that disease and you have not, is not this an opportunity 

 for the introduction of this disease into your herds? It cer- 

 tainly is through the cans in the process of separation and in 

 the cream as well as the skim milk. This is the medium of a 

 still further spread of the disease.
