Thirty-sixth Annual 'Convention 985 



Mk. Lillik: If the King system did nut work there was soin&- 

 thing the matter with the constructiou of it. There are tliousands 

 in operation which work perfectly. You may hold your handker- 

 chief near the shaft and there is draft enough to carry it up. Of 

 course the ventihiting shaft is nothing more or less than a big 

 chimney. It may not draw for the same reasons that prevent any 

 chimney from drawing. Sometimes it does not extend far enough 

 above the barn, or as you say, a hillside close by and high enough 

 might cause wind currents which would interfere with proper 

 draft. But the principle of the King system is all right and if 

 properly constructed there is no question about its working. I 

 think a muslin curtain is better than nothing, but it is a poor 

 makeshift for proper ventilation. 



Me. Matteson : A neighbor of mine had the same experience 



with the King system — the dampness and moisture it simply 



would not work, and he had a man there who was an expert. But 

 they did not take into account the location of the building. The 

 system is all right. That conuot be disputed for one moment. But 

 sometimes you have got to take into consideration locations that are 

 adverse. 



Chairman Smith : The King system of ventilation in order to 

 work has to be insulated, the tube has to be insulated, that 

 the warm air will be kept warm. If it is a thin board the 

 air is cooled at once and the circulation stopped ; whereas if you 

 make the insulation so perfect that it keeps the air warm, and 

 then put on top of the shaft a shield to prevent the wind from 

 blowing down, and that will turn from the wind all the time, 

 you will have a draft. 



Sometimes the cloth system works very well. But we tried it 

 very carefully at the experiment station and found that in a very 

 damp south wind the moisture collected on that cloth and it did 

 not work at all and was a complete failure. As one gentleman 

 said, it is better than nothing but it is not a successs at all times. 



Me. Lillie : I do not like to hear the gentleman say there are so 

 many barns where the King system cannot be put in. I do not 

 believe there is a barn in the United States where it will not work. 

 If you have a barn with stone walls like the old-fashioned bank 

 barn, with only one little window, you can still put in this system
