212 BOAED OF AGRICULTURE. [Jan., 



current of air coming down the flues on that side, which 

 makes tlie stable very cold ; so much so, that the running 

 water which I have in the stable will freeze. My stable-man, 

 when the wind blows from the west or northwest, closes the 

 ventilators on that side and opens them on the other, and in 

 that way we can have ventilation from either side, according 

 to the wind. When the atmosphere is quiet, we can take a 

 feather and go to one side, and it will fall or float ; if we go 

 to the other side, it will rise to the chimney. That is just as 

 Prof. Brewer has said. Ventilate from the top, and the air 

 will come down one side or the other. There are sixty head 

 of animals in my stable, and you will find very little difference 

 in the atmosphere. The stable is comfortable ; my men will 

 go in and milk in the morning at this season of the year with 

 their coats off; water will not freeze there, and there is no 

 odor or taint in the stable at all. 



My barn is forty by seventy. At the extreme north end I 

 have a large ventilator, five by three, running out at the top, 

 where it does not interfere with the hay or anything. That 

 is constantly open. I have another stable, thirty by forty, 

 which I built entirely without ventilation, and kept it pretty 

 €old. I had consumption in that stable, from the vitiated 

 air, I think. I then cut out spaces over the windows. I 

 had the windows at first so that I could let them fall, 

 to give that amount of ventilation, and I have three sliding 

 ■doors on each side of the forty-foot stable, and as the 

 wind changes I open or close them, on either side. There 

 are three of those ventilators, a foot square, on each side of 

 my stable, and they are opened on one side or the other, as 

 the wind may blow. Water does not freeze in my stables, 

 and they are as nearly perfectly ventilated, I think, as they 

 can be, and there is no odor and no trouble. 



Dr. RiGGS. Some twenty-five or thirty years ago, I had 

 occasion to repair a barn, to get it into condition for contain- 

 ing a stock of horses and Jersey cattle. The barn not being 

 large enough for my stock, I built an L upon the south side, 

 with a manure stable underneath, and cattle above. I had two
