THE SOY BEAN FOR OIL AND OTHER PRODUCTS. 13 
utilized in the manufacture of the milk, but quite recently it has 
been discovered that soy-bean meal, after the oil is extracted, is fully 
as useful for milk purposes as the whole bean. 
If the milk from the soy bean is used in the manufacture of products 
as a substitute for milk, the labels of such products should indicate 
that the substitution has been made ; otherwise it would constitute 
adulteration under the food and drugs act. 
In addition to its uses for flour and milk, the soy bean can be 
prepared as human food in numerous ways. The green bean, when 
from three-fourths to full grown, has been found to compare favorably 
with the butter or Lima bean. The dried beans may be used in the 
same way as the field or navy bean in baking or in soups. When 
prepared in either of these ways the dried beans require a somewhat 
longer soaking and cooking. The soy bean has been utilized not only 
in the United States but in European countries as a substitute for the 
coffee bean. When roasted and prepared, it makes an excellent sub- 
stitute for coffee. In Asia the dried beans, especially the green-seeded 
varieties, are soaked in salt water and then roasted, this product 
being eaten after the manner of roasted peanuts. 
SOY-BEAN MEAL AS STOCK FEED. 
Soy-bean meal, in addition to its use as a fertilizer, is also used as 
stock feed. In Manchuria the cake or meal, mixed with bran and 
kaoliang stalks, is used as feed for horses and mules, but only when 
very hard work is done. It is also recognized in Japan as a valuable 
feed for work animals and as a fattening feed for stock not employed 
in farm work. 
In Europe soy-bean cake ground into meal is used almost entirely 
for feeding cattle, and the low price in comparison with other con- 
centrated feeds has made it very popular. Some hesitation was 
shown in the dairy countries of Europe when the meal was first 
introduced, as it was feared that the taste of the butter might be 
affected by feeding the meal to cows. However, experiments in these 
countries proved the fear groundless, and the demand for the meal 
increased steadily. The use of soy-bean meal in America is confined 
at the present time almost entirely to the Pacific States. It is con- 
sidered a valuable feed not only by dairymen but also by poultrymen. 
Practical experience, supplemented by carefully conducted experi- 
ments in the United States and European countries, indicates the 
high feeding value of soy-bean meal for all kinds of farm stock. 
The Massachusetts (Hatch) Agricultural Experiment Station con- 
ducted a series of tests comparing soy-bean meal with cottonseed 
meal for feeding dairy cows. It was found that although soy-bean 
meal imparts a noticeable softness to butter, the cottonseed butter 
was decidedly inferior in color, flavor, and texture. Doubtless a
