the character of the grain. Rice hulls and the intangible mill loss 

 together amount to about 33 pounds for rice of the Honduras 

 type and 30 pounds for the Japan type. The hulls on the Honduras 

 type of kernel are somewhat heavier in proportion than those on 

 the Japan type of grain.

 of the ungraded rice from the trumbles in each corresponding series.
