Straw is obtained in the threshing of grains and the secur- 

 ing of leguminous seeds. Stover from corn is the product left 

 after field drying of corn grain and includes the whole plant 

 except the ears. The straws from legumes, oats, rice and other

 tubers. The root and tuber crops contain a great deal of water ; 

 the average per cent, of water in these crops is about 90 per
