Properly treated wood in many situations is 

 cheaper, more permanent, and better than any other 

 material. 



Wood preservation meets an economic need by 

 fitting wood for the exacting requirements in mod- 

 ern structures. 



Timber doesn't have to be discarded where per- 

 manence is desired. Creosote it. 



Preservative treatment permits the use of woods, 

 which without treatment have little value, or are 

 not utilized. 



Decay is never inherent in wood, but originates 

 from outside infection. 



The value of the annual output of the treating 

 plants of the United States is over 100,000,000 

 dollars.
