CREOSOTED FENCE-POSTS ARE ECONOMICAL 



These ash posts were treated with Creosote 

 in 1905, and when photographed in 1914 showed 

 absolutely no decay. Experts believe they will 

 last 15 to 20 years longer. — Photos courtesy

DAILWAYS and other large 

 ^•^ industrials use thousands of 

 fence-posts annually, but few are 

 protected from decay, with the 

 result that replacements are con- 

 tinual. An enormous saving in 

 labor and materials can be ef- 

 fected if creosoted posts are used. 



The Iowa State College of Agri- 

 culture have made a comprehen- 

 sive study of this subject and the 

 results are published in Bulletin 

 No. 158, from which the follow- 

 ing data and quotations have 

 been taken. 



ESTIMATED AVERAGE LIFE 

 IN YEARS 



Untreated. These cedar posts were set in 

 1905 and taken up for examination in October 

 1914. In each case the «ip-wood was entirely 

 gone: in post No. 1 about one-^hird of the en- 

 tire bottom rotted away ; in post No. 2 one-half 

 of the bottom decayed, while in post No. 3 

 more than one-baU of the bottom decayed.

Further interesting facts 

 are quoted from Bulletin 

 mentioned above: 



First — "By effective creo- 

 sote treatment it is prob- 

 able that woods com- 

 monly 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 inter- 

 est, creosoting 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, hickory, 

 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." 



SeveJith-'Tht posts should 

 be thoroughly seasoned 

 before treatment is at- 

 tempted, or a poor pene- 

 tration of creosote oil will 

 be secured." 



The Best Creosote for all 

 practical purposes is Bar- 

 rett's Carbosota — Grade-One Liquid Creosote Oil. 



It comes ready for use in convenient-sized packages 

 and requires no apparatus or skilled labor for its 

 application. Any one can use it properly at any time. 



It has been especially developed to meet the needs of 

 the average consumer. Green lumber or timbers cannot 

 be effectively creosoted by non-pressure processes. 

 They should be air-dry. 



Barrett's Carbosota is the "Standard" wood preserva- 

 tive for use in the Brush and Open-Tank methods of 

 treatment. It is economical, effective and convenient.
