No. 4.] STABLE MANAGEMENT. 195 



declared free from the disease by the test. The methods of 

 disinfecting are the free use of live steam wherever we can 

 get it; in every case the scraping of all woodwork, any- 

 thing that the animal comes in contact with, with a three- 

 cornered tree scraper; wash with boiling water, and then 

 wash over with bichloride of mercury. This is done in 

 cases under supervision of the commission. 



Dr. Lindsey. The farmer signs the paper that he will 

 do so. It struck me that the commission should bo a little 

 more emphatic, that this should be carried out, for I think 

 the farmer is apt to be very lax after he gets his money for 

 the tuberculous animals, if not looked after. 



Mr. Pratt. How long does this agreement extend? 



Dr. Osgood. That they will not again introduce into 

 their herds an animal until it has been subjected to the 

 tuberculin test. 



Mr. French (of Dalton). I would like to ask how 

 many animals have been killed that did not prove to be 

 diseased? 



Dr. Osgood. Under the law of 1895, 4 out of 1,732. 



Mr. Bradley. How is it proved that they were not dis- 

 eased ? 



Dr. Osgood. Lesions were not found. 



Mr. French. Do you know of any case where a man 

 has taken it from an animal ? 



Dr. Osgood. I think I know of a good many cases 

 where the evidence is about as direct as can be. 



Mr. French. In what way could it be taken ? 



Dr. Osgood. Through the milk. 



Mr. French. Why is it not necessary to stop the sale 

 of milk when some animals are condemned? 



Dr. Osgood. Do you mean in the voluntary request? 



Mr. French. Yes, sir. 



Dr. Osgood. They are all condemned that are diseased. 



Mr. French. Why not stop the use of the milk at the 

 time they are condemned ? 



Dr. Osgood. It is instantly stopped. If the farmer is 

 dishonest, and sells it, we cannot be there to stop him. 



Mr. French. Is it proved that if a cow does not respond 

 to the test of tuberculin she is free from disease ?
