"Conservation Imperative" 



The Waste "Over There" mast be replaced by the Plenty "Over Here 



> f 



Never before has the word Conservation held 

 the meaning that it does at present, nor has 

 the importance thereof been impressed upon 

 us as fully as by the gigan- 

 tic scale of the destruction 

 wrought in Europe. 



Our timber resources are 

 still immense. Waste in the 

 utilization of forest prod- 

 ucts has been, perhaps, the 

 inevitable result of plenty, 

 but today wastefulness in 

 any form is reprehensible. 



In the period of reconstruc- 

 tion more structural wood 

 than ever will be required, great as the war 

 demands are, and therefore every stick should 

 be conserved. 



Decay of structural wood is one form of 

 wastefulness which it is equally neces- 

 sary to reduce to the minimum. Every 

 class of consumers can accomplish this 

 by the application of preservative treat- 

 ments with Carbosota Creosote Oil. 



Wood Preservation is Conservation of timber 

 and labor, and an important economy one 

 that will pay large dividends, for years to come. 

 Carbosota Creosote Oil is 

 the most efficient wood 

 preservative for non-pres- 

 sure treatments. It con- 

 forms strictly to the stand- 

 ard specifications adopted 

 by the U. S. Shipping Board 

 Emergency Fleet Corpora- 

 tion, and by the U. S. Rail- 

 road Administration. 



Technical assistance to help 

 in selecting the proper 



method of treatment may be obtained gratis 



by addressing nearest office.
