mixture of hulls and the gluten part. When unmixed 

 with other parts of the kernel, the hulls are also known 

 as corn bran and the germ portion from w^hich the 

 oil has been pressed is called, when ground, germ oil 

 meal. The corn bran contains the least protein and the 

 gluten meal the most, while the gluten feed and germ 

 oil meal occupy a position between these. It should 

 be remarked that the commercial names for gluten prod- 

 ucts are not always a safe guide in their purchase. 



Residues from the manufacture of beet sngar. — An 

 industrj^ apparently now on the increase in the United 

 States, the manufacture of beet sugar, is offering to 

 farmers two waste products, sugar beet pulp and sugar 

 beet molasses. The former is the extracted beet tissue 

 from which all the sugars and more or less of other 

 soluble compounds have been removed. This pulp as 

 it leaves the factory has been found to contain an 

 average of scarcely 10 per cent of solids. One ton of 

 pulp supplies, then, not over two hundred pounds of 

 total dry substance, or perhaps one hundred and sixty 

 pounds of digestible dry substance. This means that 

 it would require six tons of pulp to supply as much of 

 digestible nutrients as one ton of good hay. The solids 

 of the pulp must be regarded as inferior to those of the 

 beets before extraction, because consisting more largely 

 of fiber and gums whose productive value is below that 

 of sugar. Experiments at Cornell University indicated- 

 that the pulp is worth about one- half as much as corn 

 silage, which would be approximately the proportion of 

 digestible matter in the two materials. 



Sugar beet pulp is, however, a useful, succulent
