ing up of silks, husks, and shelled corn," he reported. 

 "Many farmers on examining a crib of soft corn find a cone- 

 shaped pile of spoiled corn directly under the elevator chute 

 where the silks and husks have collected. Where the air 

 circulates freely, they find the corn in good condition." 



Crib Ventilators Aid Drying. 



Ventilators built from floor to ceiling thru the cen- 

 ter of a large crib, which take air from the ends of the crib 

 and the drag trench under it, virtually make two narrow 

 cribs and are very effective in drying out corn. Mr. C. W. 

 Raymond, of Watseka, is one farmer who has successfully 

 used such a shaft in his crib. The shaft is built of two-by- 

 fours about a foot apart, with boards nailed on them about 

 two inches apart. 



A vertical shaft, resembling a flue but not connected 

 to the outside, is excellent for drawing the air out of the 

 corn. The air in all parts of the crib can be kept moving 

 by having air ducts lead into this vertical ventilating shaft. 

 Many farmers have arranged such ducts by using strings 

 of drain tile hung on wire, or held in place with slats. 

 These ducts can be arranged, not only to carry the moist air 

 out of the corn, but also to bring in drier air from the out- 

 side. 



This particular ventilator is built of two-by-sixes placed 

 two feet apart thru the middle of the crib. The frame made 

 in this way can be covered either with slats or with woven 

 wire. The plan shows tile leading to the ventilator to take 

 out the moist air and additional tile extending to the out- 

 side wall of the crib to bring in drier air. The slanting 

 pieces on which these tile are supported are one-by-threes. 

 By placing the inlet tiles across the crib at intervals of four 

 feet and the outlet tile one foot above and between them, an 

 effective method of natural ventilation is provided. 



The use of tile to ventilate corn cribs is practiced rath- 

 er generally. Mr. Guy H. Husted, Scott county farm ad- 

 viser, reports that farmers have used rows of tile two feet 

 apart thru their cribs with good results. Still better re- 

 sults, no doubt, would be secured, by putting the tile in on a 

 slight slope and connecting them with a ventilating flue.
