I cannot describe how stealthy and noiseless and altogether perfect his maneuvering was. Although the trees that grew about were all small and the bushes bare, and although the white snow gave no background for concealment, he covered himself so perfectly at one time, and slipped in and out of sight so quickly at another, that although I stood with revolver pointed and cocked, I could find no opportunity for a shot. As he circled for position he came ever nearer, and I could see at one time the round head, with its short, pointed ears; at another the long, sinuous, muscular body; but they moved so rapidly that before I could shoot they were gone from sight. All the time he made no sound but a little rustle. In his final concealment I saw nothing of him but his tail, that twitched and twitched and twitched. At last I caught the glint of his pale green eye and fired. There came a snarl from behind the bush, and it was dashed to one side and the other, while round head and bared teeth and tawny body came crashing through. I pulled trigger again, and the report sounded muffled, and the smoke for an instant obscured the beast. All was white, when, like a breath, it passed, and I saw the rushing catamount not ten feet from me. I had not time to fire or crouch, but with ready legs hurled myself to one side, and threw my left arm around the tree that grew at the edge of the bank. With an awful dread I felt the ground giving way beneath me. I dropped my knife and caught the tree closer, when it, too, leaned to fall. It hung for a moment over the steep slope, and I could not save myself. The frost had not clamped the over-hang to the solid ground. The last fall rains had cut it under; the first spring thaw would have brought it down, had not my weight been thrown upon it. With a twist the tree and I fell together. I clutched my revolver desperately, despite the sickening fear of the fall, and in my grasp it exploded in mid air. Then I fell, and although my body struck easily in the snow-covered ravine, my right hand had been beaten against a sharp rock, and the birch was upon me so that I could not move. My legs were on the bank, and underneath the snow beneath my shoulders I soon felt the ice, from which stones protruded. One snow-covered rock received and supported my head. I lay upon my right side, and my right hand, swinging in a curve, had struck with force upon another stone, and lay upon the ice, the only part of my body, except my head, which was free. My left arm was pressed close to my side by the birch, which lay across my body and legs. The weight was not so great but that I could have lifted it, could I but have gained purchase. But I must at the same time lift my own body, for my hips were lower than my feet, my shoulders lower than my hips; and I could not gather ten pounds of force in that position.
