TWO-THIRDS OF EACH TREE 

 WASTED. 



"At present i.vo-thirds oi the- a\cr- 

 age tree is wasted before llie wood is 

 put to use," said C. P. Winslow. Di- 

 rector of the United States Forest 

 Products Laboratory, in an address 

 at a recent meeting of the Madison 

 Section of the Society of American 

 Foresters. "Without doul)t, a con- 

 siderable part of this waste can l)e 

 used," he added, "and it is the func- 

 tion of forest products research to 

 develop every possible new use, with- 

 in the limits of the financial resources 

 available for such work. Such better 

 utilization also has a vital relation to 

 the practice of forestry on private 

 lands, by making possible a greater 

 net return per acre, thus making con- 

 tinuous production of private forests 

 more financially attractive than at 



present." Ainnng the new uses of 

 \v(<n<\ now being developed which 

 may ha\c lu-Mfound effect upon future 

 fcjrest prndndion, Mr. Winslow men- 

 tioned the use of "built-uj)" wood, in 

 which small pieces of wood are glued 

 together into laminated parts of vari- 

 ous shapes and sizes, which can ])e 

 made just as strong and useful as an 

 ecjual amount of solid wood. The in- 

 creasing uses of laminated vv'ood 

 make it reasonaljle to assume that 

 many of the forests of the future can 

 he ])rofital)ly cut at an earlier age 

 than at ])resent with much closer 

 utilization of the trees grown, thus 

 naturally increasing the financial re- 

 turn per acre. The greater utilization 

 of wood waste and wood in the small- 

 er sizes for chemical products and 

 paper pulp was also given as a fertile 

 field for research.
