mixture of these meals in proper proportions would tend to produce a 
butter of the proper consistency. The value of soy-bean meal for 
producing meat. milk, and butter is well established. It is one of the 
cheapest of the highly nitrogenous feeding stuffs and is therefore 
one of the most economical for balancing rations deficient in nitrogen. 
Table VII shows the prices per short ton of soy-bean cake in com- 
parison with other oil cakes which enter largely into the feeding 
rations of cattle in European countries.

Alleged injurious effects from feeding soy-bean products have been 
reported to some extent in the United States and Europe, and their 
cause has been the subject of careful investigation. As yet. however, 
no proof is to be had of soy beans or their products causing any 
injurious effects. Owing to its high content of protein, the meal 
should be used' with the same precautions as are observed with other 
highly concentrated feeds, to avoid digestive troubles. 
Table VIII gives analyses of soy-bean meal compared with sim il ar 
concentrated feeds. As regards digestibility, soy-bean meal com- 
pares very favorably with other oil meals.

SOY-BEAN MEAL AS A FERTILIZER. 
The utilization of soy-bean meal for fertihzing purposes has been 
confined almost entirely to Asiatic countries. For centuries bean 
cake has been sent to the sugar plantations of southern China, and 
its use gradually spread to the plantations in Java and other tropical
