Seventy-five samples of the fancy head, or "head," rice, as it is 
also termed, were secured. The mill yield of this grade varies from 
45 to 85 pounds per barrel of rough rice, with an average of about 59 
pounds when no extra fancy head grade is made. The results of the 
analyses are given in Table VIII. 
Table VIII also shows that the second head grade is composed 
principally of half grains, but contains also a large percentage of 
three- fourths grains. The mill yield varies from 10 to 30 pounds per 
barrel of rough rice, with an average of 19 pounds.

The screenings grade contains principally half grains, but differs 
from second head rice in that it contains but few three-fourths 
grains and a large proportion of one-third grains. The mill yield 
varies from 5 to 25 pounds per barrel of rough rice, with an average 
of 15 pounds. The figures for this grade are given in Table VIII. 
The brewer's rice grade contains the smallest particles of milled 
rice and is composed almost entirely of pieces less than one-third of 
a grain in size. The mill yield varies from 3 to 13 pounds per 
barrel of rough rice, with an average of 8 pounds. The results of 
the analyses are given in Table VIII. 
The mill yield of line rice approximates 89 pounds per barrel of 
rough rice, and the grade includes all the clean product except 
brewer's rice. As would be expected, there is a very wide variation 
in the proportions of the particles of different sizes in this grade. 
Table VIII gives the results of the analyses.
