milk or producing beef and mutton the feeding of root crops 

 is satisfactory. On account of the tonic eflfect, roots give re- 

 sults far above what the chemical composition would indicate. 

 In the South many crops can be grown on the same piece of land 

 in a season; roots may be grown in the early fall and winter 

 at a time when the land is often idle and harvested in time for 

 the regular planting of the summer crops. Roots and tubers can 

 be stored away and kept for feeding, provided the storehouse 

 is well aired and kept at a low temperature. Bull. 243, Cornell, 

 N. Y., Experiment Station, says: "If corn mieal is worth $20 

 a ton or more in New York State, economy in the production of 

 roots would be indicated."

Grains and Seeds. — Some of our principal grains and seeds 

 used for stock feeding are corn, cotton-seed, rice, oats, barley, 

 rye, flaxseed, wheat, beans and peas. Most of our grains and 

 seeds must be thoroughly dried before they are stored away. 

 If they are not completely dried, they are liable to ferment and 

 decompose. Such deterioration spoils them for feeding pur- 

 poses. A full description of the grains, seeds and their by-prod- 

 ucts will be given in the following sections under commercial 

 feed stuffs. 



Production of Some Feeds. — The following table^ gives the 

 production of some farm crops for the year 1908. All of the 

 seeds and more especially their by-products are used extensively 

 for feeding farm animals and a study of the table should im-
