Lot C consisted of No. 4 Japan-type rice. This lot contained 
considerable red rice and was light and chaffy on account of imma- 
ture grains. It cupped 40 pounds to the bushel. In milling this 
rice the stones were set lower and the hullers set very loose. 
The milling results on this lot are given in Table 11.

Lot D consisted of No. 1 Honduras-type rice. This lot was slightly 
seedy and weather damaged. It cupped 41 pounds per bushel. In 
milling, the stones were raised on account of the long grain, and the 
hullers were set very loose, as in milling rice of the Japan type, and 
were fed slower. 
The milling results on this lot are given in Table 13.
