The Forest Service of the United States estimates that the American lumber mill- 1 produce no less than 36,000,009 cords of waste every year. About one-half of i« goes into the furnaces as fuel; the rest is burned as refuse. A comparatively small quantity, 20,000 tons or more, n ground into wood flour, just as grain was ground in old-time mills. The product is divided between two widely different industries, the manufacture of dynamic and the manufacture of inlaid linoleum. ■Both require a white or very ligdtcoloured flour, which is obtained mainly from spruce, fir. white pine, and poplar. The flour used in making dynamite mus' he very absorptive, so that there w'll 02 no leakage of nitro-glycerine "from the finished product; it must also be white, since lightness of colour in dynamite m regarded as a sign ox freshness.
