By-Products of Lumber.

Thanks to the actives of the United States department of agriculture, and especially the forest products laboratory, ways have been revealed by which well nigh every scrap of a tree can be put to good account, and the waste material of one plant or factory can be utilized gainfully In the manufacture of commodities turned out by others, says the Scientific American. Through the medium of the woodwaste exchange much is being done to promote the further working up of byproduct lumber, but the practice is relatively only in its infancy with us. Finally it should be kept in mind that the alcohol that can be made from sawdust is chemically Identical with grain alcohol, and therefore valuable for many industrial purposes. As a source of energy, in place *of gasoline, It is used, successfully and extensively abroad. A ton of so-called wood refuse will yield as ’much as 20 gallons of alcohol.
