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 w T as 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.
