THE SOY BEAlsT FOE OIL AISTD OTHEE PEODUCTS.

cake has been confined almost wholly to the Western States, owing 

 principallj 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 

 A m eri ci^u -gro\vn 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 Ainerican-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 soy bean 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.
