No. 6. DEPARTMENT OF AGRICULTURE. 529 



MR. COOK: I will be very frank with you, my friend. If I thought 

 that anything you have said would counteract anything I have said, 

 I should regret very much that I had ever come to Harrisburg. At 

 the same time I do not question that the ventilation you have got 

 in your barn is fairly good, but I beg of you, if you are going to do a 

 thing, do it right. It is so much better that you get this fresh air 

 from out doors. I do not want to debate this question with this 

 gentleman who is a good deal older than I am, but I do not want 

 you to take his view point and leave mine out. 



The SECRETARY: Isn't it possible if the air cools, that it would 

 come down and vitiate the hay? 



MR. COOK: That might be rather farfetched, because the con- 

 densation would probably take place, if it took place at all, in the 

 upper part of the barn. 



The SECRETARY: Wouldn't it come down in being condensed? 



A Member: It gets out at the roof, don't you worry about that. 



MR. COOK: I have worked at this thing for six years, harder 

 than I ever worked on anything before. Here in my friend's case, 

 there is no doubt one of those exceptions that sometimes occur, 

 but do not do it; run it out through the roof, and do it right. 



MR. HERR: The out-take flue is always close to the floor. 



MR. COOK: Close to the floor and close to the ceiling. 



MR. HERR: Does that center flue that you talk about — would 

 that come down to the floor? 



MR. COOK: Yes, that would come down to the floor above the 

 cows and it would take the place of these little openings you see 

 in these flues, which of course are opened and closed at will. All 

 we do in our own barn is to open and close these upper flues, as may 

 be required. 



A Member: They are warm weather flues? 



MR. COOK: Yes, warm weather flues. 



A Member: When you open these warm weather flues, is your 

 ventilation just as good? 



MR. COOK: Most certainly it is. 



I remember a cold day when the wind had just changed to the 

 south, and the atmosphere was full of moisture without any air 

 currents forming at all outdoors, and it was hard to get any cur- 

 rents to rise upwards. That was the day we held our meeting in 

 this barn. We had four hundred people, in addition to fifty cows, 

 and yet we were able to maintain this sort of a pure atmosphere. 

 That was a pretty trying time to maintain pure air. We are able 

 to carry a temperature of between fifty and sixty degrees; when it 

 gets up to sixty, we blow off some of this air. I might tell you that 

 in making some of the tests and in watching them very carefully we 

 had a period when the temperature ranged from freezing to twenty 

 degrees below zero, and we were able to keep the temperature
