considerable range of climate, from cool 

 temperate to sub-tropical. They yield 

 on the average a crop per acre similar 

 to ordinary beans, but they differ from 

 other beans in that they are rich 

 in oil. The ordinary beans and peas 

 grown in Europe and America contain 

 very little oil. The Soya beans are also 

 richer in albuminoids than any of our 

 ordinary beans and peas, They are, 

 in fact, among the richest and most 

 concentrated vegetable foods known. 

 Some of the American accounts of the 

 cultivation of Soya beans— which are 

 known in that country as soy— suggest 

 that it might be worth making further 

 attempts to cultivate them in Britain. 

 Possibly the previous failures to grow 

 them successfully were due to want of 

 knowledge of their peculiarities or to 

 the use of unsuitable varieties, or to 



other causes which might be overcome 

 with further knowledge. 



There are great numbers of analyses 

 of Soya-beans on record. The older 

 ones are chiefly German, American, and 

 Eastern analyses, but during the past 

 eighteen months a great number of 

 analyses have been made in this country, 

 The recorded analyses of these beans 

 show that they contain from 15 to 23 

 per cent, of oil, and from 28 to 43 per 

 cent, of albuminoids. The ordinary legu- 

 minous seeds which we use in this 

 country — peas, beans and lentils — con- 

 tain about 2 per cent, of oil, and from 

 20 to 30 per cenc. of albuminoids. An 

 average sample of Soy beans contains 

 about 17 per cent, of oil and about 37 

 per cent, of albuminoids. The following 

 table gives analyses of Soy beans com- 

 pared with our ordinary broad beans 

 and kidney beans: —

In the above table the Soy bean ana- 

 lysis No. 1 is an average of twenty- 

 five samples of yellow beans taken from 

 a German publication. No. 2 is an 

 average of eight samples grown in 

 the United States. Nos. 3, 4, and 5 are 

 analyses made in the writer's labor- 

 atory of samples of beans recently 

 imported from Manchuria. It will be 

 noticed that my analyses of the Man- 

 churian beans now being imported into 

 this country show a higher percentage 

 of albuminoids than the German and 

 American averages. In no single ana- 

 lysis that I have made has the percent- 

 age of albuminoids fallen as low as 34. 



This is confirmed by analyses made 

 recently by others. 



There is a large number of different 

 varieties of Soy beans, They are divid- 

 ed into flat-shaped and round-shaped 

 varieties, according to form. They also 

 occur in various colours, such as white, 

 yellow, green, brown and black. Those 

 recently imported into this country 

 from Manchuria are chiefly yellow round 

 beans. But black, brown and green 

 beans are found in many parcels mixed 

 in greater or less quantities with the 

 yellow beans. All the great different 

 varieties appear to be similar in so far
