BULLETIN 330, U. S. DEPARTMENT OF AGRICULTURE. 



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.
