June on jack-pine sand where sugar beets had failed, produced two tons 

 of hay per acre. Evvard of the Iowa Station found soy beans or cow 

 peas surpassed for hog pastui-e by rape, clover and alfalfa on soil where 

 the latter crops flourished. 



"The soy bean is one of the most important agricultural plants of 

 northern China and Japan. So great is the production of this seed, or 

 grain, in Manchuria, that in 1908 over 1,500,000 tons of soy beans were 

 shipped from three ports, chiefly to Europe. The bean-like seeds of the 

 soy bean, which carry from sixteen to twenty-one per cent of oil, are 

 used for human food and for feeding animals. The oil is used for human 

 food and in the arts, and the resulting soy bean meal is employed as a 

 feed for animals and also for fertilizing the land, the same as cotton seed 

 meal. This plant produces the largest yield of seed of any legume 

 suited to temperate climates, but at the present time is grown in this 

 country chiefly for forage. Soy beans are adapted to the same range of 

 climate as corn, early varieties having been developed that ripen seed 

 wherever corn will mature. On account of their resistance to drought, 

 they are especially well suited to light sandy soils. When grown for 

 seed, the yield commonly varies from twelve to forty bushels per acre, 

 equaling corn on poor soil in the gulf states. 



'The seeds of the soy bean are the richest in crude protein of all the 

 various seeds used for feed, besides being rich in oil. Being highly 

 digestible, they contain fully as much digestible crude protein and 

 considerably more digestible fat than linseed meal. Because of the 

 demands for seed, soy beans have not yet been extensively employed in 

 this country for feeding live-stock. For dairy cows, soy beans are 

 slightly superior to cotton seed meal, but as they cause so^t butter, they 

 should be fed sparingly. For fattening cattle, soy beans are only 

 slightly inferior to cotton seed meal. Rich in protein and mineral 

 matter, they are well suited to growing animals; equal parts of soy 

 beans and shelled corn proving superior for lambs to equal parts of oats 

 and corn in a trial by Humphrey and Kleinheinz at the Wisconsin Sta- 

 tion. Owing to their richness in protein, soy beans should always be 

 used in combination with carbonaceous concentrates. The seed should 

 be ground for horses and cattle, but this is unnecessary for sheep and 

 pigs. In the South, pigs are often grazed on soy beans when nearly 

 mature, thus saving the harvesting cost. No other plant so little grown 

 in the United States at this time promises so much to agriculture as the 

 soy bean, which not only yields protein-rich seed and forage, but builds 

 up the nitrogen content of the soil. 



"The residue after the oil has been extracted from soy beans carries 

 as much digestible protein as choice cottonseed meal, eleven per cent 

 more carbohydrates and somewhat less fat. During recent years a 

 considerable amount has been imported to the Pacific coast states from
