Medicine is not going to change the draught. It is not 

 going to have any effect on the wind. Supposing that the 

 medicine apparently cures you; it does not cure the draught 

 which was the cause of your trouble, and its effects cannot 

 be permanent because there you are still in the same place 

 in the same draught and are subjecting yourself to a renewal 

 of the same trouble. Don't you think the only sensible thing 

 for you to do is to stop the draught? You would do so if 

 you were sure that the draught was the cause of your 

 trouble. 



People do not seem to be sure that draughts are the cause 

 of roup. There are all kinds of roup cures. Their makers 

 keep telling you the same thing, year after year, and you 

 never get at the real facts. You are positive that a draught 

 will give you a cold; so it is with a hen. She catches cold, 

 her head swells, and this keeps on until she dies. 



Now, books and poultry papers tell you that a house hav- 

 ing three air-tight walls and a roof is draught-proof, and, 

 as an example, it is pointed out that you cannot blow air 

 into a bottle. True, you cannot blow air into a bottle, but 

 you must remember that a poultry house is not shaped like 

 a bottle. Break off the neck of a bottle and you have a 

 larger opening; now blow into it and at the point of contact 

 between the air you are blowing and the air coming out a 

 resistance is met. The air inside the bottle forces the air 

 you are trying to blow into it backward, and at the point of 

 contact there is is a back-draught created. Now, again, if 

 you blow into the bottle at an angle or along the edge, a 

 whirling draught is created, and you must remember that 

 the bottle is absolutely air-tight except at one end. 



Is there any argument here? Isn't this a positive fact? 



It is, and any one that will make investigations on his own 

 account can prove this to his own. satisfaction.
