These Ash posts were treated with Creosote 

 in 1905. and when photographed in 

 1914 showed absolutely no decay. Ex- 

 perts believe they will last 15 to 20 years 

 longer. Photos courtesy Iowa State College

Proper Creosote 

 Treatment to Increase 

 the Life of Fence Posts 



TWENTY-FIVE million fence posts, 

 with a value of about $4,000,000, 

 are used annually by the farmers of 

 but one of the agricultural states of this 

 country, as reported in Bulletin No. 158 

 of the Iowa State College of Agriculture. 



The value of creosoting these posts is 

 indicated by the following table which 

 shows the comparative life of treated 

 and untreated fence posts of five 

 species of wood commonly used.

 In Years 



Untreated 



Untreated. These Cedar posts were set in 

 1905 and taken up for examination in 

 October. 1914. In each case the sap-wood 

 was entirely gone; in post No. 1 about one- 

 third of the entire bottom rotted away; in 

 post No. 2 one-half of the bottom decayed.

Further interesting facts 

 are quoted from Bulletin 

 mentioned above : 



First — "By effective cre- 

 osote treatment it is 

 probable that woods 

 commonly used for posts 

 may be doubled in life 

 (white cedar, oak, etc.)" 



Second — "By treatment, 



many species, at present 



almost valueless, can be 



made to last twenty-five years or more, with only 



a small addition in cost for treatment (willow, 



soft maple, cottonwood, elm, etc.)" 



Third — "Figuring the investment at 6% simple 

 interest, creosote reduced the annual cost of the 

 less durable fence posts by about one-half." 



Fourth — "In selecting posts for treatment take the 

 native soft-wooded trees and save the oak, hick- 

 ory, black walnut, etc., for other purposes." 



Fifth— "In creosoting select small posts, those 4^ 

 inches in diameter, if of sufficient strength. They 

 are cheaper, and when creosoted will last as long, 

 or longer, than seven-inch posts. 



Sixth — -"See that the posts are thoroughly peeled 

 of the inner as well as the outer bark." 



Seventh — "The posts 

 should be thoroughly 

 seasoned before treat- 

 ment is attempted, or a 

 poor penetration of creo- 

 sote oil will be secured."
