While in many cases the amount of preservative which can be in- jected in this way would not be sufficient to fully protect timber in direct contact with the ground, in most cases where treatment is indicated in buildings it would be sufficient. Such treatments could be carried out by any one at any point, and the local treatment of timber would probably be cheaper than when done at a distant cen- tralized plant. In the East, such a local method of treatment is being carried out by at least two lumber dealers within the writer's ac- quaintance. If treated timber were put on the local markets as a standardized product, as readily available to the man who needs 100 feet as to him who uses it by the 100,000 feet, the favorable results experienced by the public in the use of the treated product would in the course of a few years create a demand and be a stepping stone toward a more profitable lumber in- dustrJ^ BRANDING STRUCTURAL The discussion now leads Fig. 41.—Wagon loaded with fragments of lumber to be hauled away.

Such a practice is of particular value in the case of dimension timbers where a standardized uniform product, graded particularly on strength and durability, must be supplied. It is customary at the present time to so brand longleaf pine for export, but the practice is very little followed for the interior tr^
