No. 6. DEPARTMENT OF AGRICULTURE. 531 



fact we have had one ex-Governor and the present Governor with 

 us to-day, and I suppose a whole lot of men who want to be Gover- 

 nors. I am not sure whether that is so or not, but I am glad that 

 the time has come when the man on the farm can look with longing 

 eyes and expectant eyes to these positions of responsibility and I have 

 longed for the time to come when the farmer could say that he knew 

 as much about his business as a professional man knows about his 

 business. Again thanking you people and you, Mr. Chairman and 

 Mr. Secretary, I bid you good-bye. 



On motion, duly seconded, a unanimous vote of thanks was re- 

 turned to Mr. Cook for his excellent addresses. 



MR. COOK: Mr. Chairman, I would like just to say that I believe 

 I have never talked on the question of ventilation to an audience 

 that I feel now has a better understanding of it than this. I have 

 talked to people who I thought knew, but when I got through, they 

 didn't; but I think this audience knows. 



The SECRETARY: I thank you for the compliment in what you 

 have said. 



PROF. VAN NORMAN: These Pennsylvania Dutch barns with 

 big banks and standing walls, is it possible to provide methods of 

 ventilation that will overcome f*he difficulties in their case? 



MR. COOK: Here is a very good way indeed; to get the intake 

 flues into these so-called bank barns. 



MR. COOK: Take away the dirt down to a point at least three 

 feet from the stable ceiling, put down a box or flue on the outside, 

 cut an opening through the wall and connect the inside flue through 

 the outside. These flues will have to be fifty per cent, larger than 

 where the side of barn is exposed, because we loose the effect of 

 wind pressure. 



MR. VAN NORMAN: Take the air into the bottom in that case? 



MR. COOK: Take it in just the same; turn around and carry the 

 flue up there (indicating on diagram). 



A Member: Wouldn't it do just as well to put it in at either 

 end? 



IMR. COOK: It will do fairly well if the barn is not too long and 

 the flue — the out-take flue is on that side of the barn. 



Now there is this bank here, this side is banked the whole length, 

 and we do not want to put an intake flue in there; it would be bet- 

 ter if you did, but there is a way that you can get out of it; put 

 the intake flue right in that corner (indicating on diagram). Now 

 put the intake flue right there; don't that strike you? Then we 

 have got air currents forming right along next to this wall that will 

 prevent condensation. 



The SECRETARY: But you must remember, Professor, that that 

 bank is on the ends, too. 



MR. COOK: Then on the ends, I would dig down there. 



DEPUTY SECRETARY MARTIN: When you go down, you want 

 to put in both light and ventilation. You can put both light and 

 ventilation there by digging away there, can you not?
