cake has been confined almost wholly to the Western States, owing 
principally to the high cost of transportation. 
During the last few years efforts have been made at various times 
to interest the cotton-oil mills of the South in the utilization of 
American-grown soy beans as an oil seed, and experiments were 
made by a few mills. No extensive work was entered upon until 
the latter part of 1915. A shortage of cottonseed in the South and 
a surplus of soy-bean seed in eastern North Carolina led to an increased 
interest in the possibilities of this crop. Several cotton-oil mills in 
North Carolina, after preliminary tests, entered upon an extensive 
production of soy-bean oil and meal. This is the first large manu- 
facture of soy-bean products from American-grown seed. Several, 
cotton-oil mills at the present time are taking an active part in the 
development of this new industry with American-grown beans.. 
With seed at $1 a bushel and the present prices received for oil and 
cake, the mills have found it profitable for them to express the oil. 
An industry which promises to be of importance in a further 
utilization of the soybean is the manufacture of " vegetable milk." 
At the present time a factory in New York State is being equipped 
for this purpose. The development of this new enterprise will 
depend primarily upon the demand created among different indus- 
tries not only for the milk, but for the flour or meal remaining after 
the milk is manufactured, which is valuable either as stock feed or 
for human consumption. 
Table V shows the imports of soy beans, bean cake, and bean oil 
into the United States during the last six years. Prior to 1914 
soy beans were not classified separately in the customs returns.
