the various governments had some little difficulty at first in meet- 

 ing aircraft specifications. 



While waterproof glues have been in existence for some years, 

 they were not well known and little information was at hand as to 

 the correct procedure for their successful use. During the war 

 the Forest Products Laboratory at Madison, Wis., has been work- 

 ing on problems that seemed to give trouble to the plants engaged 

 on war contracts. Much help has been given manufacturers and 

 a large staff of specialists has been engaged in obtaining informa- 

 tion and developing new ideas in the uses of glues and wood. 



It must not be inferred that absolute information is at hand 

 concerning all phases of the uses of woods, and that the labora- 

 tory will be at once a panacea for all ills. Even though much has 

 been learned, there is still much to be done. It is merely pointed 

 out that the government maintains under jurisdiction of the Forest 

 Service an institution equipped to handle many of the difficult 

 problems continually arising in the manufacture of furniture and 

 panels. 



Douglas Fir Veneer for Trunks 



The use of Douglas fir veneer in the manufacture of trunks 

 is becoming quite an important use for the material. Two Los 

 Angeles trunk companies utilize nearly 400,000 feet in the manu- 

 facture of trunks annually. 



English Walnut Veneer 



An English walnut tree which grew in Nuneham Park, England, 

 was sold some time ago for $100. The log changed hands sev- 

 eral times, finally reaching the United States, where it was re- 

 duced to 60,000 feet of veneer which sold for $7,500. 



Perfecting Waterproof Glue 



Remarkable advances have been made in the manufacture of 

 waterproof glue within recent months. Glue may now be had 

 which is so resistant that panels made with it may be immersed 

 under water ten days or boiled one day without showing any 

 signs of separating into individual layers and without materially 

 lessening their strength. Such panels have great possibilities in 

 the manufacture of furniture, trunks, door panels, wagons, as 

 well as airplanes.
