THE MILLING OF RICE. 
19 
methods of the Association of Official Agricultural Chemists. For 
better comparison, these results are also calculated to the moisture- 
free basis. They show that the product from the " plantation huller " 
is lower in percentage of ash, ether extract, and crude fiber than the 
rice from the old mortar- and-pestle mills, indicating a more thorough 
scouring of the grains in the huller.

Chemical analyses were made of four series of mill samples of 
Honduras rice and of three series of samples of Japan rice. These 
samples, which represent different grades of rough stock, were ob- 
tained in various parts of Louisiana, Texas, and Arkansas and are 
considered to typify the chemical effect of rice milling as now exem- 
plified in those States. Table VII gives the results of these chemical 
analyses.
