192 Miracles Ahead! 



is largely of wood. (Here are the other reasons "why certain 

 woods may get scarce.") 



Germany's continued progress in wood chemistry was 

 made possible by conservation and reforestation programs 

 which gave her renewable sources of supply, and our forest- 

 products industries also are working to insure a steady supply 

 of wood in the United States. 



Forest Conservation 



"By scientific cutting," wrote Robert M. Hallett in the 

 Christian Science Monitor, "it is possible to increase the an- 

 nual new growth to a point where the yearly increment ap- 

 proximately balances the normal amount of timber used. 

 Industry spokesmen stress that timber is a crop like corn or 

 wheat and can be harvested and renewed. Actually trees 

 need to be cut to insure a future abundant supply of this 

 natural resource, because trees grow old and rot if they are 

 not harvested to make way for a new crop. Wood researchers 

 hold that continuation of their work promises increasing divi- 

 dends in productive land use, waste utilization and employ- 

 ment. 



"The world has not grown out of the 'wood age'; it is only 

 now entering it," concludes Hallett. 



Glass Miracles 



The third member of this wonder-working trio is glass. 

 Dr. W. C. Taylor, chief of glass technology of the Corning 

 Glass Works, Corning, New York, states in the American 

 Glass Review that "the world would be left in chaos if glass 

 were removed transportation and communication would be 

 stopped, hospitals and laboratories would be at a loss, and 

 there would be a real blackout."
