Creosoted Wood is Permanent 



THIS fact is recognized in the 

 structure illustrated above. . 



Modern engineering practise de- 

 mands durability and employs 

 such materials 

 as meet this re- 

 quirement. 



Unless wood is 

 protected against 

 decay it is not 

 permanent when 

 exposed to con- 

 ditions favorable 

 to the develop- 

 ment of wood-destroying agencies. 



Creosoted wood for structural 

 purposes is equally as serviceable 

 as concrete and more economical 

 than steel. 



The Open-Tank System is adapt- 

 able to all conditions; the treat-

ment is economical, and the re- 

 sults are such as to offer an efficient 

 protection against decay of all tim- 

 ber structures which are not ex- 

 posed to severe 

 mechanical abra- 

 sion when in ser- 

 vice. 



Under certain con- 

 ditions the Brush 

 Treatment alone is 

 available or desir- 

 able, especially 

 where the chief re- 

 quirement is to re- 

 tard decay at all points of contact. This 

 method has proved effective and is to 

 be recommended. 



CARBOSOTA Grade-One Creosote 

 Oil is a pure coal-tar creosote especially 

 refined for the Brush and Open-Tank 

 Methods of treatment. It is the 

 standard and generally recognized 

 as such.
