1. Economic Uses. 

 The soy bean/ Glycine hispida, Moeiieli, is a native of the 

 Orient, where it is grown ehielly for its seed, which constitutes 

 one of the staple ])rodncts. J. J. Rein^ states that in China and 

 Jai)an the soy beau ranks first of leguminous crops in extent, 

 variety of use and value, excelling all other vegetables in nu- 

 tritive qualities, and when projjerly jjrepared second to none in 

 flavor. While so}' beans are eaten plain cooked, S2:)ecial foods 

 prepared from them seem to be more generally used, prominent 

 among which are several fermented products known as slioyu, 

 an aromatic table sauce; miso, a thicker relish; and natio, a 

 mush; also a bean curd or cheese called iofu. These prepara- 

 tions and others are described more fully by Ixein,- C. F. Lang- 

 worthy,-"' S. 11. Angell,-* Kellner,-''' M. Inoyue," II. C. P. Geer- 

 ligs" and Bloch.'^ Such products, rich in protein, prove a 

 valuable adjunct to rice. Of the land under cultivation in 

 Manchuria, from one-eighth to one-sixth, according to ]^. 

 Ssenunow,^ is devoted to the soy bean, and the production of 

 an edible oil from the seeds forms one of the principal indus- 

 tries. Soy beans are considered too valuable in the east to be 

 fed to horses or cattle, though the straw and sometimes the 

 green fodder are used for that purpose.
