 procure, therefore care is taken to use 

 wood that is least affected by contact with 

 earth. Of the common woods for this pur- 

 pose, locust and chestnut are the best. 

 The more seasoned the wood is the better 

 and to insure longer life the ends in the 

 ground can be treated, in fact all wood 

 coming in contact with the earth should 

 be treated for preservation. Charring 

 is one way. The end is held over a fire 

 until it is well blackened both the tip 

 and the sides to a point above grade. 

 Other methods of preservation are peeling 

 and seasoning and painting. 



Surface brush painting, while not dur-

 applying white-wash, petroleum, tar cre- 

 sote and coal tar creosote. Creosote is 

 the best when put on hot in two or more 

 coats. Paint the tops as well as the butts. 

 As the brush work does not enter far into 

 the wood, better results are obtained 

 by dipping the ends into the liquid, this 

 however takes more material but less la- 

 bor.
