could, by scientific methods of wood using, pro- 

 duce just as good products by using 10 to 50 

 per cent, of the tree as they do by using 

 all of it. The furniture industry not infrequently 

 wastes from 40 to 60 per cent, of the raw 

 lumber which it buys. Much of this waste 

 could be saved by cutting the small sizes 

 of material directly from the log instead of from 

 lumber. It is also essential that sizes of material 

 used in these industries be standardized. 



The Forest Products Laboratory has per- 

 fected practical methods of building up material 

 from small pieces which otherwise would be 

 thrown away. For example, shoe lasts, hat 

 blocks, bowling pins, base-ball bats, wagon bol- 

 sters and wheel hubs are now made of short 

 pieces of material which are fastened together 

 with waterproof glue. If this method of built- 

 up construction can be made popular in all sec- 

 tions of the country, very great savings in our 

 annual consumption of wood can be brought 

 about. As matters now stand, approximately 

 25 per cent, of the tree in the forest is lost or 

 wasted in the woods, 40 per cent, at the mills, 5 

 per cent, in seasoning the lumber and from 5 

 to 10 per cent, in working the lumber over into
