FORESTS--STATISTICS 65 in. 1925. Abundant supplies of raw material, and a reliable supply of labour contribute to the advantages thatthe province offersfor the establish- ment of these subsidiary industries. Bird's-eye view of mills at Shawinigan Falls, Quebec Destructive Distillation of Wood.—At present there are nine factories in Canada for destructive wood distillation of which four are located in Quebec. Charcoal, methyl hydrate, acetate of lime, acetic acid, formaldehyde, and turpentine are the principal products. The value, of products in 1926 was $773,054. The woods used are birch, beech, maple, oak, and ironwood, and for the most part only material unsuitable for the manufacture of lumber is used, being such as would be cut for sordwood, or wasted in lumbering operations. All portions of the tree are used, even to the small branches, and any piece larger in diameter than five inches in split to admit of the easier penetration of the heat of decomposition and the freer evolution of the gases. The capacity of the four plants in the province is 168 cords a day. The wood is cut into about four-feet lengths and is seasoned for a year or more to dry. When ready for distillation a cord weighs about 3,700 pounds. Wood distillation presents a good opportunity for the econo- mical utilization of the hardwood waste in wood-using factories. Other Wood-using Industries.—There are numerous other indus- tries using sawn lumber and the products of the sawmill as their raw mate- 28105—5
