thenate, zinc naphthenate, phenyl mer- 

 cury oleate have added a few months to 

 4 years to the life of untreated stakes. 

 Some water-borne preservatives have pro- 

 vided less protection than standard pre- 

 servative oils, when retentions have cor- 

 responded to commercial usage, others 

 compare favorably.) 



i960, pp. 1-8. (U.S., In Mississippi stakes 

 impregnated with 0.2 lb. fluor chrome 

 arsenate phenol (Tanalith) per cu. ft. 

 had an average life of 10 years; stakes 

 pressure treated with the fire-retarding 

 formulation containing ammonium phos- 

 phate and ammonium sulfate lasted 2 to 

 3 years; with these salts plus borax and 

 boric acid stakes lasted 6 years; copper 

 naphthenate is more effective than zinc 

 naphthenate; stakes pressure treated with 

 phenyl mercury oleate in naphtha have 

 lasted 5 to 9 years. In Canal Zone, Panama, 

 stakes pressure treated wtih chromated 

 zinc arsenate (Boliden salt) 0.33 lb. per 

 cu. ft. had an average life of 9 years, 

 while those with 1.0 lb. had an average 

 life of 15.3 years; stakes treated with 

 0.6 lb. per cu. ft. of Tanalith had an 

 average life of 14 years; 5% solution of 

 pentachlorophenol in light fuel oil — 5-10 

 lb. per cu. ft. have lasted 14 years; 8 to 16 

 lb. per cu. ft. of coal tar creosote have 

 lasted over 13 years.) 



1961, pp. 1-8. (Mississippi, stakes pressure 

 treated with ammonium phosphate and 

 sulfate lasted on the average 2-3 years. 

 With these salts plus borax and boric acid 

 the life on an average was 4 years.)

 treated southern yellow pine posts in- 

 stalled from 1936-1938 had an average 

 life of 3.3 years. Untreated longleaf pine 

 posts installed in 1949 had an average life 

 of 2.3 years, those treated with No. 2 fuel 

 oil or Wyoming residual petroleum oil 

 retention 5 to 7 lb. per cu. ft. have an 



average life of 8 to 9 years. Of southern 

 yellow pine posts, installed from 1936- 

 1941, treated with borax-boric acid all 

 failed after 20 years, average life 10.6 

 years. Posts treated with the following 

 preservatives have had failures totaling 

 less than 10% and should last 33 years 

 or longer on an average: water gas tar; 

 50-50 solution of creosote—crankcase oil 

 (latter may contain chlorinated naphtha- 

 lenes which injure cattle on contact) ; 

 tetrachlorophenol 4.8% in crankcase oil; 

 pentachlorophenol 3% and 4.8% in 

 crankcase oil; copper sulfate and sodium 

 arsenate applied by double diffusion and 

 zinc meta arsenite. Posts in test in 1936- 

 1941 treated with other preservatives have 

 an estimated average life of 13 to 32 

 years.) 



i960, pp. 1-16. (U.S., Mississippi, posts 

 treated with the following preservatives 

 (installed from 1936-1941) have had fail- 

 ures totaling 10% or less, should last 36 

 years or longer on an average; water gas 

 tar; 50-50 solution of creosote — crankcase 

 oil; pentachlorophenol 3% and 4.8% in 

 crankcase oil; copper sulfate and sodium 

 arsenate applied by double diffusion and 

 zinc meta arsenite. Posts treated with 

 other preservatives have an estimated 

 average life of 13 to 35 years.) 



1961, pp. 1-14. (U.S., Mississippi, experi- 

 mental untreated southern yellow pine 

 posts installed from 1936 to 1938 at the 

 Harrison Experimental Forest, Saucier, 

 Miss., had an average life of 3.3 years. 

 Untreated longleaf pine posts installed 

 in 1949 had an average life of 2.3 years, 

 while those treated with a No. 2 fuel oil 

 and with Wyoming residual petroleum 

 oil have an estimated average life of 

 5 and 8 years, respectively. Of southern 

 yellow pine posts installed from 1936 to 

 1941, those treated with borax-boric acid 

 have all failed with an average life of 

 10.6 years and those treated at the 

 groundline and top with Osmoplastic 

 have all failed after an average life of 

 1 1.2 years. Posts treated with the follow- 

 ing preservatives and installed from 1936 

 to 1941 have had failures totaling 10 per- 

 cent or less of the number installed and 

 should last 38 years or longer on an aver-
