28 THE SOY BEAN ; HISTORY, VARIETIES, AND FIELD STUDIES. 



It has been possible to determine the history of these, in part at 

 least, which is of value in interpreting the older records. 



ITO SAN. 



Ito San was among the varieties introduced in 1899 by Prof. W. 

 P. Brooks, of Amherst, Mass., and by him called Early Yellow. 

 Later, Mr. E. E. Evans secured seed of it and in 1902 called it Ito 

 San. Mr. Evans writes that he subsequently secured it "from half 

 a dozen sources in the United States and Japan." The same variety 

 was also among those introduced by Prof. C. C. Georgeson, of the 

 Kansas Agricultural Experiment Station, and grown in 1890 " and 

 subsequent years. This conclusion is based on the identity of nine 

 varieties obtained from the Rhode Island Agricultural Experiment 

 Station in 1903. This station had previously obtained several varie- 

 ties from the Kansas Agricultural Experiment Station in 1892.'' 

 Three of the varieties from Rhode Island had exactly the same names 

 as those published in Bulletins 19 and 32 of the Kansas Agricultural 

 Experiment Station, namely, Eda Mame, Yellow Soy Bean, and 

 Kiyusuke Daidzu. All three of these are Ito San. 



Ball " gives a list of numerous American sources tlirough which 

 this variety was secured under such nam.es as Yellow, Early Yellow, 

 and Early White. It was also grown at the Virginia Agricultural 

 Experiment Station in 1905 as Japanese pea, as shown by later 

 cultures at the Arlington Experimental Farm of seed from this 

 experiment station. 



Among the introductions of the Office of Foreign Seed and Plant 

 Introduction it is represented by No. 6326, received in 1901 from 

 Tokyo, Japan, and No. 21818, obtained from Vilmorin-Antlrieux & 

 Co., Paris, France, as "Yellow Etampes." It is quite probable that 

 this is one of the varieties grown by Professor Haberlandt in his 

 experiments, as all of his varieties were grown at Etampes and other 

 places in France.'^ We suspect that this is also the variety that 

 was distributed by the United States Patent Office in 1853, as most 

 of the early accounts point to this or a closely similar variety. These 

 accounts refer to it as Japan pea, Japanese pea, Japan bean, and 

 also coffee berry. «
