THE MILLING OF RICE.

RICE OF THE JAPAN TYPE. 
The commercial grades of the Japan type of rice generally now 
made in the mills are (1) fancy head, or "head," rice; (2) screen- 
ings; (3) brewer's rice. Samples of this type of rice were obtained 
from the same sources and the analyses performed in the same way 
as previously described for rice of the Honduras type. Fancy head 
rice is composed very largely of whole grains. The whole-grain per- 
centage is larger than in the corresponding grade of the Honduras 
type, because the shape of the kernels of the Japan type is more nearly 
round; consequently, there is a smaller amount of breakage. The 
mill yield of this commercial grade varies from 92 to 105 pounds per 
barrel of rough rice and averages 96 pounds. Table IX gives the 
analytical results for this grade.

The only commercial grade of broken Japan-type rice used as such 
for food is that of screenings. The results of mechanical analyses 
given in Table IX show that it is very similar to Honduras screen- 
ings, but the yield is much smaller. In commercial practice the two 
are often mixed. The mill yield varies from 3 to 11 pounds per 
barrel of rough rice and averages 5 pounds. 
Japan-type brewer's rice is not distinguished commercially from 
Honduras brewer's rice, and the two are used interchangeably to 
supply the trade. The mill yield varies from 3 to 10 pounds per 
barrel of rough rice, with an average of 5 pounds. The analytical 
results from the samples of this grade are given in Table IX. 
BY-PRODUCTS. 
The mill yield of rice bran varies with the severity of scouring 
and the texture of the rice, and approximates 22 pounds per barrel 
of 162 pounds of rough rice of the Honduras type and 20 pounds 
for the Japan type. Rice polish approximates in yield 6 pounds 
per barrel of rough rice for both the Honduras and the Japan 
types, but, like the bran, it varies considerably with mill practice and
