<i>Title:</i> Lowly corn cob has many uses. Thanks to successful experiments of the Department of Agriculture, corn cobs can now be made into many valuable by-products. Dr. W.W. Skinner is shown pointing to a block of heat insulating material made from corn cob. Next to the corn cob are samples of by-products, including furfural, lignin, ethyl alcohol, cellulose, xylose, adhesive, acetic acid, glucose, carbon and a printing plate made from phenol-furfural resin. In front of the cob are skeins of rayon dyed with colors made from lignin of the corn cob, 11/20/30
