The by-products of kick MILLING. 
11 
Lot B consisted of No. 3 Blue Rose type rice. This lot contained 
considerable red rice and some cracked and over-ripe grains, and was 
of very ordinary quality. It cupped 43 pounds to the bushel. The 
stones were lowered to the usual height, the hullers set loose, and fed 
at regular speed. The rice was brushed with large feed on brush. 
The whole process was regulated throughout to preserve the grain 
rather than to obtain a highly milled rice. 
The milling results on this lot are given in Table 9.
