The effect of bolting in all cases was a decrease in fiber, but further 
than this no general rule can be deduced, as conditions such as fine- 
ness of grinding and the size of the meshes of the bolts exert more 
influence than the mere fact of bolting. The markedly high acidity 
in the meal from mills 9 and 36 was doubtless due to the length of 
time elapsing between grinding and analysis, which for reasons 
already stated was from 9 to 12 days. 
DEGERMINATED BOLTED ROLLER-GROUND MEAL. 
The general name "cream meal" is applied to degerminated, bolted, 
roller-ground meal when made from white corn, but various terms 
are used for the corresponding product from yellow corn. Analyses 
of both white and yellow meal and of the corn from which the meal 
was milled will be found in Table 4. The samples were from mills 
located in the Northern States and in Tennessee. All the mills 
were equipped with rolls and modern machinery for cleaning the 
grain as well as for separating and drying the products. Most of the 
mills employed degerminators, while others depended on corrugated 
rolls for loosening the germ and bran from the endosperm.
