Results at the Illinois station show practically no loss 

 the second year. In fact after corn has become thoroughly 

 air dry, the weight will then fluctuate with the humidity of 

 the air, the variation amounting to as much as 3 per cent. 

 (See 111. Bui. 113, p. 363.) 



Shrinkage is partly due to the loss of water, but as 

 pointed out by Ten Eyck ^ the loss of moisture alone does 

 not account for the entire decrease in weight. There is 

 a decrease in actual dry matter probably due to some 

 process of oxidation. 



Marketing 



176. Corn is usually marketed as shelled corn and is 

 seldom shipped in ear. About 60 per cent of the corn 

 crop is consumed on the farms where produced. About 

 10 per cent is sold locally to feeders and about 25 per cent
