of considerable importance. Starch is a valuable product 

 manufactured from the grain of corn which is used both as 

 food and for starching or stiffening fabrics. It is likewise 

 converted into a form of syrup known as corn syrup. Corn 

 meal is the finely ground corn, largely used as food. In 

 the manufacture of starch and corn meal, the germs of corn 

 are removed. These germs are heated and pressed and 

 a valuable oil is extracted from them. This oil in the crude 

 form is used in painting and as a lubricant, and is vulcanized 

 into a cheap grade of rubber. It may also be refined and 

 used as a food product. Corn flakes and cerealine are two 

 very palatable breakfast cereals also manufactured from corn. 

 Alcohol and distilled liquors are manufactured largely from 

 this grain. The pith of corn stalks is used in .the manu- 

 facture of explosives and as a packing material for battle 

 ships. The cobs are made into pipes, and the stalks are 

 now being used to some extent in the manufacture of paper. 

 Corn husks are used for making mattresses and for packing. 

 140. By-products. The by-products from corn canning 

 factories, the husks and cobs, are often used in the form of 

 silage or as green feed. Corn cake, a by-product left from 

 the manufacture of corn oil from the germs of corn, is also 

 a valuable stock food. Gluten meal, a by-product from 

 starch factories, is richer in protein and considerably richer 

 in carbohydrates than linseed meal. It is highly prized as 

 a stock food. Corn bran, another by-product in the manu- 

 facture of corn meal, corn starch, and breakfast foods, is a 

 valuable feed for stock, though it is not as valuable pound 

 for pound as common wheat bran. It is quite commonly 

 mixed with gluten meal, and the mixture is then sold as 

 gluten feed. Distillery slops, a watery by-product in the 

 manufacture of alcohol, is of considerable importance as 

 stock food, though naturally it must be fed locally as it is
