FORTY-FIRST ANNUAL CONVENTION 173 



ground was in the herd of a man who Hved five miles southwest 

 of Buchanan. He had five or six dogs, left his tools out under 

 a tree behind the barn in the sun and storm. You know the kind 

 of man. We always have trouble with that kind of a fellow. 

 They don't come to the Dairy Association meetings or read the 

 papers, and they find more fault with the county, state and 

 nation than all the intelligent men in the township. Their horses 

 are lame, their harness patched up with binder twine and rusty 

 wire, and evidently their chickens roost over the buggy top. The 

 word came in that this man's dogs were running loose. There 

 had been no disease around him for quite a while. He was fined 

 $22.33, ^^^ i^ about a week after that his own cattle came down, 

 and we had to kill them. 



We had 70 isolated outbreaks outside the original area of 

 infection, that came from infected virus from a certain serum 

 company of Chicago. Up to the time I left Michigan, about 

 four weeks ago, we had only six or seven secondary outbreaks 

 from those 70 isolated cases. You have 40% of all the infec- 

 tion of the United States right here in Illinois, and 20% is sec- 

 ondary infection. The rest is from shipments of cattle from 

 Chicago, or infected virus and creamery shipments, and the rest 

 is secondary infection. 



Curiosity, ignorance and indifference are the cause of some 

 secondary infection. There are a whole lot of people that are 

 very curious to see the disease. They have got to see it. They 

 sneak along the hedge and the back fence to see somebody's sick 

 cattle, and then they regret it. It is very contagious. Dogs 

 carry it, particularly in a community where we slaughter. The 

 blood is scented by the animals, and if there happens to be any 

 blood around the hole, half a dozen dogs assemble and roll and 

 fight in this and carry it home. Cats and rats carry it. The 

 feathers of a pigeon that had been feeding in an infected feed 

 lot were found to be infectious for 12 hours afterward. 



What is that virus they carry? The virus of this disease is 

 found in the blisters or vesicles that form. They break and the 

 contents of the vesicle escape and contaminate the mouth or the 

 milk. The manure is contaminated from the vesicles formed in
