Photograph by A. R . Moore THE ONE ENEMY THE BIG TREE FEARS-THE LUMBERMAN In felling a big tree a platform is first built above the buttresses of the trunk. On this two men stand, each with a double-bladed axe, with which, with broad swinging strokes, they gradually chop their way in to the heart. Then with a long cross-cut saw they attack it from the other side. With smooth, flowing movement, rather than rough, jerking motion, they pull the keen-toothed blade back and forth, keeping it well greased all the time, until they approach the center from that side. A series of wedges follow the saw to keep the tree from settling and closing the path it has cut. These wedges gradually force the giant over toward the chopped side until finally, with a mighty swaying, it passes out of the perpen dicular, and with a crash like the terrific roar of a raging sea falls prone along the line predetermined for its cradle.
