1959m, pp. 12-14, 16. (U.S., Jacksonville, 

 Fla., building constructed of untreated 

 lumber in 1954, inspected by VA badly 

 damaged by decay. Hidden value of 

 house built in 1956 of pressure-treated 

 lumber. Cost allowed in mortgage loan 

 and loan insurance, protected against both 

 termites and decay, estimated in U.S. 

 Dept. Agriculture's Wood Handbook at 

 500 million dollars per year.)

 damaged by termites, protection pressure- 

 treated lumber.)

1959s, p. 66. (Western Australia, dip-dif- 

 fusion treatments of Pinus radiata with 

 sodium arsenite or fluoroborate-chro- 

 mium-arsenic mixture protect against 

 Coptotermes as best available pressure 

 treatments. Chlordane or white arsenic 

 added to glue line of karri plywood at 

 all levels effective against termites. Plas- 

 tic, gypsum plaster boards and insecticide 

 treated hardboards with small additions 

 of aldrin or dieldrin effective. Both 

 dense and "no-fines" concrete termite- 

 proofed by adding small amount dieldrin. 

 Surface treatments with 5% pentachloro- 

 phenol only effective wood preservative 

 against Nasutitermes exitiosus after 3 

 years. Tests of more than 30 types of 

 plastic-covered, lead-sheathed, or bitimum- 

 served cables have been under way against 

 Mastotermes at Rollingstone, Queens- 

 land.) 



1960a, pp. 14-17. (U.S., 3 types houses, base- 

 ment, crawl-space, slab-on-ground, (1) 

 limited protection: for basement houses, 

 pressure preserved sills (cost $20 to $40 

 more) ; for crawl-space houses, pressure 



preserved lumber in substructure (cost 

 $i20-f>i50 more); for slab-on-ground 

 houses, pressure preserved sills, plates, 

 sleepers, columns, studs, porch lumber. 

 (2) full protection: pressure preserve all 

 framing lumber, cost 2% total price. Sills 

 must be preserved, condensation leads to 

 decay, setding. Shields repudiated, be- 

 come racket, no protection against decay. 

 Soil poisoning only short-term protec- 

 tion, will not prevent decay. Pressure- 

 treated wood safest.) 

 1960J, p. 4. (U.S., homes up to 45 years old 

 prove pressure-treated lumber provides 

 most efficient protection.) 

 1960m, p. 4. (U.S., properly pressure-pre- 

 served lumber most effective protection 

 against decay and termites, low cost in- 

 surance. For limited protection, cost $20 

 to $40 for average-sized home in areas 

 where termites and decay range from 

 slight to moderate; where range from 

 moderate to heavy (28 States and D.C.) 

 $120-$ 1 50. For full protection necessary 

 in 8 States, especially in Florida and Cali- 

 fornia, use pressure-treated lumber from 

 sills to roof boards, cost 2 to 2/4 percent 

 additional.) 

 1960c, 1 pp. 20, 24. (Hawaii, termites con- 

 trolled by use pressure-treated wood and 

 kiln drying, local plants, Wolman salts 

 for lumber and plywood, pentachloro- 

 phenol for millwork and trim, 80% wood 

 treated Douglas fir, 10% Philippine ma- 

 hogany.)
