powdery substance, which is removed from the rice kernel. The 

 rice kernel is corrugated or rough, and in giving to it the 

 smooth appearance and pearly lustre that the trade demands, 

 the rough parts are smoothed down and brushed off with spec- 

 ial machinery. Rice meal and rice polish are excellent feeds 

 when sweet. Sometimes the meal contains a high content of 

 fat (12-20 per cent.) which is objectionable because of its li- 

 ability to turn rancid, in which case the feed is not fit for use. 

 Rice polish is a good feed for fattening hogs and cattle.

Sugar By-Products. — About 20,000,000 gallons of cane mo- 

 lasses (blackstrap) are produced annually in the United States. 

 A gallon weighs about 12 pounds. A great deal of this output is 

 used for feeding live-stock. The demand for cane molasses for 

 feeding is not satisfied by the Louisiana output so a great deal 

 is being imported from the tropical countries, notably Porto 

 Rico and Cuba. There is also a large quantity of beet molasses 

 used for feeding. The amount used is hard to estimate because 

 many factories work over their molasses so that there is none 

 left for feeding. However, it is questionable at the present 

 whether it is not more profitable to sell the molasses as stock 

 feed than to work it over for its sugar content. 



The sugar by-products used for stock feeds are cane mo- 

 lasses, beet molasses, beet pulp and sorghtim cuite or molasses. 

 I. Cane molasses. The cane molasses sold for stock feed is 

 usually the final product from the manufacture of cane-sugar.
