CORN OR MAIZE 53 



a certain per cent of bran and mineral elements. These two 

 feeds, together with oil cake, have a very important place in the 

 trade of concentrated stock feeds. The starch remaining on the 

 incline table is termed green starch, and when removed from the 

 tables is diluted with water until it forms a milky liquid. From 

 this liquid by careful refining corn starch is removed. After 

 filtering, it is dried in kilns and ground fine, run through revolv- 

 ing silk screens, and is then boxed or barreled and put upon the 

 market for home consumption or for the trade. By varying 

 time and temperature in refining, various grades and kinds of 

 starch are made. From the starch, corn sirup, corn sugar, mill, 

 laundry, and edible starch are made. Green starch when sub- 

 jected to a high heat under pressure in the presence of hydro- 

 chloric or certain other acids forms glucose. Sugar made from 

 corn in this manner is used in the making of sirup, in the brewing 

 of ales and porters, in fermenting beers, and in the making of 

 caramel. 



42. Miscellaneous uses. The grain of corn is used in the 

 making of alcohol, but because of the price of corn and the com- 

 parative cheapness of other material that can be used as a source 

 of alcohol, it is not likely that it will be used extensively for this 

 purpose. Corn stalks and the pith from the stalks have been 

 used successfully in the making of paper. Whether or not the 

 making of paper from them will be placed on a practical basis will 

 depend largely upon the invention of suitable machinery. If 

 corn stalks can be utilized in this way, the great loss in the large 

 fields of the Middle West will be greatly reduced. The pith of 

 the corn stalks is also used in the manufacture of gunpowder, 

 while in the packing of battleships it is especially valuable, 

 since when wet it will swell and thus close an opening that may 

 be made by a projectile. The husks of corn are used in up- 

 holstering and in the making of mattresses and door mats. 

 Cob down is also used in upholstering and in the packing of 

 pillows. The utilization of the corn plant is extending into many 

 trades, and doubtless it will in the future be found useful in many 

 ways unknown at present.
