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

 ing of leguminous seeds. Stover from com 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 

 cereal plants, and stover from corn are used for feeding. The 

 straws from grain plants, other than oats and rice, are gener- 

 ally too poor for feeding and may be used for bedding.

Roots and Tubers. — Turnips, carrots, rutabagas, mangel wur- 

 zels (a kind of beet) and beets are the principal root crops 

 used for feeding. Potatoes (Irish and sweet) are sometimes 

 fed but they are generally grown for human consumption and too 

 expensive to be utilized for stock. Irish potatoes are known as 

 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 

 cent. That is for every 100 pounds of roots or tubers there 

 are only 10 pounds of dry matter or actual feed. For making
