IMPORTANCE AND CHARACTER OF MILLED RICE IMPORTED. 
are very long and very slender and have a bright luster, but other- 
wise they resemble the Siam rice. 
A few samples of several other rice types, including "Rangoon/ 
"Maulmein, " and "Saigon/ 7 were secured. These types of rice are 
now of so little commercial importance in the United States that they 
are not described nor are the analyses of such samples tabulated in 
this bulletin. 
Plate I shows whole grains of the various types of rice described. 
MECHANICAL ANALYSES OF SAMPLES OF IMPORTED RICE. 
Practically all of the samples of imported rice upon which this 
investigation was based were secured at the American ports of entry 
by officials of the Bu- 
"■¥f *r%- • •

reau of Chemistry. The 
samples and the infor- 
mation secured at the 
time of sampling were 
submitted by that bu- 
reau totheOffice of Grain 
Standardization, where 
the mechanical analyses 
were made and the tabu- 
lating work was done. 
Only those factors 
which directly concern 
the commercial grading 
or affect the market 
value of rice were con- 
sidered in the analyses, 
and they were deter- 
mined on a 50-gram 
portion of each sample. 
In making the size sepa- 
ration, the weighed por- 
tion of the sample to 
be analyzed was first 
shaken on a flat metal 
screen with round holes 
six sixty-fourths of an 
inch in diameter. The 
particles which passed 
through the screen were weighed, and the results, calculated to a 
percentage basis, are recorded in Table II in the column headed 
" Through No. 6 screen." The whole grains and broken particles 
which did not pass through the screen were carefully separated by
