py.pRODUCTS OF THE
 LUMBER INDUSTRY

Washington, D. c., Feb. S.-W waste in the logging industry in the United ctotes amounts to 15 to 20 per cent of tbo timber cut, or about a billion and holf cubic feet of wood annually. cown,ill waste also amounts to several hn,;on cnbic feet of wood, although no+ all of it is absolute waste. A bull letin on the subject of lumber by-pro- dncts inst issued by the Bureau of Eoroion and Domestic Commerce, De- nor+ment of Commerce, makes claim that only 320 feet of lumber Is used for each 1000 feet that stood in the forest.
 IL was the prodigious waste of American forest resources that led the Rnreau of Foreign and Domestic Con- merce to plan a thorough study of the methods of utilizing the waste pro- duets of the lumber industry, here in the United States and in those Euro mean countries that have made the most distinct progress in this line. In the older and more thickly settled countries of the old world necessity led to careful utilization of the forests Imanv years before the subject was seriously discussed in this country. And in these older countries many methods have been worked out that should be of value in this country now that the old-time wasteful methods have been brought into disrepute. The plan was to have the American industry profit as much as possible by the hardearned experience of the old er countries
 Unfortunately the war upset the plan completely, and there is no imme- diate prospect of making the proposed Investigation But as the Bureau had already engaged Prof. H. K. Benson, wel-known authority on the subject 1t was decided to go ahead and make study of the industry in this coun- try. The bulletin just issued is the result of this study. It gives a de- Unite idea of how far the manufac- lure of lumber by-products has been developed in this country, how far it hay be reasonably be expected to de- Felop in the future, and just what Eome of the problems are that confront he industry
 There is complete review of the Tood-dlStillation industries, the manu- lecture of tannin extract, the manu- acture of the various kinds of wood pulp used in the paper industry, the reduction of ethyl alcohol from saw 'ust, the manufacture of producer gas ma number of other minor products, ne extent to which these industries fe carried on is outlined, and in cases nere an industry is not prospering dlScuSslon of the causes for such a Ondltlonu Is given. Import and ex- oft statistics are included when avail he.
 The annual production of wood pulp
