Seen by a representative of The Canada Lumberman, Mr. Scammell ex-. Mr. Ernest H. Scammbll. plained the method in which he is interested and which he is confident will find favor with Canadian lumbermen. "The process consists," said Mr. Scam- mell," in impregnating the wood with a sac- charine solution, to which, for particular purposes, are added certain antiseptic sub- stances or chemicals. The wood is subse- quently artificially dried and is then quite ready for use. "Any kind of wood may be treated in this manner. A log may be cut into planks on the same day as the tree is felled, put through the process, and, after drying, is more efficiently seasoned than as if it had been dried naturally for years. In addition to this it is thoroughly sterilized and rendered proof against dry rot and decay. "The requisite plant consists of open tanks of suitable dimensions, heated preferably by steam pipes, capable of raising the liquor to boiling point; ordinary drying chambers and storage tanks for holding the liquor. "The wood, which is not subjected to any external pressure or vacuum at any stage of the process as it is received, is immersed in a cold solution in open tanks. This solution is gradually raised to boiling point, and is main- tained at this temperature for a certain time, depending on the size and density of the wood. The whole is then cooled and the wood is removed and placed in a drying chamber. When sufficient desiccation has taken place the cha
