 impregnated with beta-naphthol in oil, 

 borax-boric acid, 10% creosote and 90% 

 crankcase oil, crankcase oil, and Osmo- 

 plastic (15-in. band application) had 

 average life 11 to 15 years; posts treated 

 with 21 other preservatives have lasted 

 longer or should last longer, including 

 steeping, osmose, double diffusion as 

 well as pressure. Coal-tar creosote, penta- 

 chlorophenol, tetrachlorophenol, Celcure, 

 coal tar, and copper sulfate and sodium 

 arsenate (double-diffusion) are over 92% 

 effective.) 



1953, pp. 1-42. (Comparison of wood pre- 

 servatives in stake tests; untreated south- 

 ern yellow pine sapwood stakes had an 

 average life of i year in the Canal Zone, 

 Panama; 2 to 3 years at Saucier, Miss., 

 Bogalusa, La., and Jacksonville, Fla.; 5 

 to 6 years at Madison, Wis. Untreated 

 Douglas fir plywood stakes had an aver- 

 age life of I to 4 years at Saucier, Miss.; 

 those glued with phenolic and urea-resin 

 lasted longer than those casein-glued, 

 which had an average life of i year. 

 Douglas fir stakes had a life of slightly 

 more than 2 years. Untreated yellow 

 birch plywood stakes had an average life 

 of 2 to 3 years. In the Canal Zone stakes 

 impregnated with 0.5 to i.o lb. of chro- 

 mated zinc chloride per cu. ft. lasted 

 5 to 7 years, with 1.5 lb. of zinc chloride 

 5 to 7 years, and with 0.6 lb. of Tanalith 

 12 years. At Bogalusa, La., stakes im- 

 pregnated with 0.2 lb. of Tanalith and 

 with 0.25 lb. of sodium tetrachlorophe- 

 nate per cu. ft. have averaged 10 and 8 

 years respectively; in Panama 0.25 lb. of 

 sodium pentachlorophenate or tetrachlo- 

 rophenate have given life of 7 and 5 years 

 respectively; 0.33 lb. (anhydrous) Boliden 

 salt 9 years. 



In Mississippi fire-retarding formulation 

 of ammonium phosphate and sulfate 

 plus borax and boric acid lasted 6 years.
