Tiger, who had been carefully scrutinizing every paw-print, but following up none, as he saw I evidently was not after small game that day, now bounded off along the edge of the forest, and I watched him proudly as, with nose close to the snow and tail high in the air, he ran hither and thither, the very picture of canine beauty and intelligence. Suddenly he stopped short, snuffed fiercely at a track in the snow, and then, with sharp, eager barks that sounded like a succession of pistol-shots, and startled every nerve and fibre in my body into intense excitement, sprang over the snow with mad haste, until he brought up at the foot of a tree just opposite me on the other side of the glade. For some moments I stood as if spell-bound. I felt that nothing less than a bear-trail could have put Tiger in such a quiver. Perhaps he had struck the track of the bear, about whose immense size father and the boys had talked so much. I confess that at the thought my knees trembled, my tongue parched as though with hot thirst, and I stood there utterly irresolute, until all at once, like a great wave, my courage came back to me, the hunter instinct rose supreme over human weakness, and grasping my gun tightly, I hurried across to where the dog was still barking furiously. A bare, blasted tree-trunk stood out gaunt and gray, in marked contrast to the dark masses of the pine and hemlock around. It was plainly the ruin of a magnificent pine, which once had towered high above its fellows, and then paid the penalty of its pre-eminence by being first selected as a target for the lightning. Only some twenty feet of its former grandeur remained, and this poor, decapitated stub was evidently hollow and rotten to the roots, for deeply scored upon its barkless sides were the signs of its being nothing more or less than a bear’s den—the admirably chosen hiding-place of some sagacious Bruin. My gun was loaded with an extra charge of powder and two good bullets. I put on a fresh cap, made sure everything was in good order, and took my stand a few yards off from the tree to await the result of Tiger’s audacious challenge. Minute after minute crept slowly by, but not a sound came from the tree. The tension of nerve was extreme. At length I could stand it no longer. If the bear was really inside the tree-trunk, I must know it immediately. Looking up, I noticed that an adjoining hemlock sent out a long arm right over the hollow trunk, while a little above was another branch by which I could steady myself. Taking off my snow-shoes, and laying my gun at the hemlock’s foot, I climbed quickly up, Tiger for a time suspending his barking in order to look inquiringly after me. Reaching the branch, which seemed strong enough for anything, I walked out on it carefully, balancing myself by the one above, my moccasined feet giving me a good foothold, until I was right over the deep, mysterious cavity.
