Basic underlying data on the chemical composition of wood andon the effect of varying chemical composition on the physical and me-chanical properties have been entirely lacking; methods for makingthe chemical analysis have not even been completely developed. Thelaboratory has made a fair start on this work, and has made progressin the refinement of methods of analysis. The analysis of severalspecies of wood has been completed. Conclusion This, in brief, outlines the major fields of work done bj^ thelaboratory during the first years of its existence. The formative. A Decexxial Record 37 period can definitely be said to have been passed. The work in woodproducts research had been clearly defined and many plainly blazedtrails had been opened through this little traveled field by the timethe world war assumed for the United States a more critical the war was over, these trails were widened to broad highwaysover which traveled many agencies and interests that sought the helpof this institution in solving problems vital to the welfare of nations. War Work The declaration of war on April 6, 1917. found the laboratorywith a fund of basic information on wood and wood products, well-developed apparatus and equipment for research and a small butwell-organized staff numbering among its members men with nation-wide reputations in their individual lines of research. Better still, thepersonnel, largely composed of those who had seen the birth of thelaboratory or helped in its early grov\i;h, was possessed of a
