COEN HARVESTING 201 



(2) The larger proportion of shredded stover that is 

 eaten ; 



(3) The greater economy in handling shredded stover, 

 which can either be baled at once or blown by the shredder 

 into the barn; 



(4) The finer condition and greater value of the manure 

 that is free from long corn stalks, and the cleaner condition 

 of the field from which corn stalks have been removed. 



Against these advantages must be placed the cost of 

 shredding, including cost of power, labor, and interest, 

 depreciation, and repairs on the shredder. These several 

 charges have sometimes been found to range between 

 $1.50 and S3 per ton of stover. 



186. Corn cribs. In cribs, or buildings intended for 

 the storage of corn, three aims should be kept in mind : 

 (1) ventilation, (2) prevention of injury by rats and mice, 

 and (3) minimizing the injury from attacks of weevil and 

 other grain insects. In most Southern cribs, the only care 

 is usually to provide ventilation. This is done by making 

 the sides of slats, or narrow planks nailed on the inside of 

 the framing, in a horizontal position. Such a slatted con- 

 struction is probably best for the storage of large amounts 

 of unhusked corn, where there is the chance that some of 

 it may be wet or immature when harvested. Even the 

 slatted cribs can be made rat-proof by lining them through- 

 out, on sleepers, studding, and joists, with strong wire 

 netting, usually with meshes about one fourth inch in size. 

 The additional expense is considerable, but in the end this 

 expenditure is profitable. 



Sometimes a small, detached crib is rendered rat-proof 

 and mouse-proof by placing it on tall pillars, the upper
