erated so rapidly that probably it is going to be a very effective 

 method of disinfecting. It consists in putting the water con- 

 taining the formaldehyde into a jar that contains permanganate 

 of potash and then getting out of the room just as quickly as 

 possible. 



Ques. Do you think it will be as effective as the corrosive 

 sublimate ? 



Ans. In careful hands I think it will, and the work has to 

 be carefully done with the corrosive sublimate. I shouldn't 

 w^onder if sometimes it would be wise to do both things. You 

 do not get the corrosive sublimate into all the cracks and crevices 

 quite as you can get this gas. and both might be done to advan- 

 tage. 



Now when we get clean from the disease, how arc we going 

 to keep clean? I would like to tell a story, one that has been 

 repeated in practice a great many times in the State of Maine. 

 One of the most progressive men in a neighborhood was not 

 satisfied with the cattle his father had left him on the farm. He 

 wanted better stock. He fitted up his barns somewhat and went 

 out and bought some registered stock of the breed that he pre- 

 ferred. He bought with a great deal of judgment, he did not 

 rely entirely upon his own judgment, and he did not spare 

 expense particularly. He got the best animals of that breed he 

 could get and brought them home. He took good care of them 

 and bred them wisely, weeding out his herd and keeping only 

 the best. He took his cattle to the fairs and exhibited them, and 

 his judgment in buying and breeding was commended by the 

 judges. He carried home the blue ribbons. He got his herd up 

 to the capacity of his farm, and then he had some surplus stock. 

 He had advertised at the fairs and now he was advertising 

 through the papers and buyers commenced to come. He was 

 just in a position to reap the fruit of his effort of years, practi- 

 cally his life up to that time. He sold an animal and the man 

 who bought it soon came back to him and told him that the 

 animal was not right, she was diseased. He investigates the 

 condition of the herd and the State buys the most of them and 

 turns them over into fertilizer. He has been breeding tubercu- 

 losis all the time. That is not a new story. They are not doing 

 that as much as they did, but it is a story that has a great many
