effort on the part of the farmer himself. This method is 

 recommended by the United States Forest Service as the 

 best. 



Fifteen cents is probably near the maximum if we consider 

 the cost of fuel and labor. 1 Considering the annual expense 

 of a treated post as compared with an untreated post, we 

 find that the increased life of the treated post, in spite of its 

 higher initial cost, makes its annual cost lower by one to 

 three cents. At that rate a long line of fence would pay 

 fairly well. 



Saving per year per mile of fence with treated posts, $4.32. 



The agents of the carbolineum companies assert that a 

 simple dipping with carbolineum, at a cost of three cents 

 a post, is as effective as the more expensive treatment 

 with creosote. This has never been adequately tested. 



A community, by buying one of these treating plants 

 and cooperating in the use of it, could greatly reduce the 

 cost of treatment and this without any inconvenience to 

 themselves. The capacity of one plant would probably 

 be enough for all. 



1 The average cost of treatment is less than ten cents.
