It is of interest to know something of the composition of the grain 

 from which flour is made. Xot only is the skill of the miller a factor in 

 the making of good flour, but the character of the grain has much to do

with the quantity and quality of the flour. The expert miller determines 

 the quality of the flour not only from the color of the grain, but from 

 the amount of gluten.
