2/6 BOARD OF AGRICULTURE. [Jail., 



Two of the other animals were in a considerably advanced 

 state of decline. We killed all four last November. Quite 

 a number of dairymen were invited to see the slaughter, and 

 to examine the animals, but it happened to be an exceptionally 

 cold, stormy day, and there were but few present. Those 

 that were present, however, were thoroughly satisfied that all 

 four were diseased. They were also thoroughly satisfied that 

 three of the four were badly diseased with tuberculosis. 



As I said, particularly during the last year of the life of 

 those young animals that were fed upon the milk of these 

 cows, they began to develop symptoms of the disease after 

 they had been fed for two or three years. There were two or 

 three cases. We had other cases, however, where the young 

 stock did not show signs of the disease. 



The last experiment that we tried was this: We took the 

 offspring of two cow^s that had been tested with tuberculin, 

 and which did not respond. We took those calves about the 

 first of May, isolated them from the cows in a small pasture 

 of an acre or two, and then took the milk of two of the tuber- 

 culous cows and carried it twice a day to those calves, and fed 

 them for a period of six months. We used the greatest pos- 

 sible care that no germs got into the milk in any way from the 

 clothing of the attendants, or in any other way so far as we 

 could prevent it. After a period of six months we examined 

 these calves by the tuberculin test, and no response was re- 

 ceived. We took pains that those calves did not go near the 

 barn with the' tuberculous cows, but as winter came on we 

 took them to another barn some forty rods distant from that 

 barn, and put them in there for winter quarters. In some way 

 one of those animals got hold of some food which was not 

 agreeable to it, and had an attack of indigestion, and the next 

 morning was found dead. We called in a veterinarian and 

 asked him to make a careful examination, and see if he found 

 any signs of tuberculosis, and he said that he did find unmis- 

 takable signs of it in the liver of this animal. The other was
