This oldprocess meal was made bygrinding the whole grain, andit therefore contained thelarge percentage of oil whichis in the chit or heart. Thisexcess of oil made it difficultto preserve the meal fresh andsweet, its keeping quality be-ing low, and it was not a safeproduct for commercial pur-poses. The improvement in commilling is by the adoption ofthe roller reduction processsimilar to that used in wheatmilling, but requiring muchgreater power, and by thisprocess a flour is producedquite as impalpable as the bestgrades of wheat flour. Through the use of veryingenious machinery the chit, or germ, is mechan-ically removed from each grain of corn before itpasses into the rolls, by this means removing all buta trace of oil from the meal or flour. The product bythis process loses some of the distinctive corn flavor,. Pig 93—Use of Cellulose inWarships The accompanying- sketchillustrates the use of cellulose, aproduct of corn pith, in pro-tecting warships from shot andshell. If a shell from the enemypierces the side of the ship be-low the water line, and passesthrough three feet of corn pithcellulose into the ship, the cellu-lose will swell up so quicklythat no water will get in. Anumber of United States war-ships are thus protected. 318 THE BOOK OF CORN but the loss is more than offset by the gain in keepingquality, and corn flour can now be used or shippedunder the same conditions as wheat flour. Corn beingwithout gluten in its composition this flour must beused in connection with strong wheat flour, and whenproperly blended as much as thirty
