I peered eagerly in, but of course saw nothing save darkness as of Egypt, and, half laughing at my own folly had turned to retrace my steps, when suddenly, without the slightest warning, the bough on which I stood snapped short off a few feet from the trunk. For one harrowing instant I clung to the slender branch above, and then, it slipping swiftly through my fingers, with a wild shriek of terror I plunged feet foremost into the awful abyss beneath. Just grazing the rim of the tree’s open mouth, I fell sheer to the bottom, bringing up with such a shock that the fright and fall combined rendered me insensible. How long I lay there I cannot say. When I did come to myself, my first impulse was to stand up. And words cannot express my relief when I found that, although much shaken up, no bones were broken, thanks to the accumulation of rotten wood at the bottom of this strange well. But oh, what a fearful situation was mine, and how bitterly I reproached myself for my folly! Shut up in the heart of that hollow tree; four long miles from home and help; utterly unable to extricate myself, for the soft decayed sides of my prison forbade all attempts at ascent; only a few biscuits in my pocket; not a drop of water, and already I was suffering with thirst; and, to crown all, the possibility, ay, the certainty, of the bear returning in a few hours, while I had no other weapon of defence than the hunter’s knife which hung at my belt. Although it was mid-day now, intense darkness filled my prison cell, and the air was close and foul, for Bruin had evidently been tenant of the place all winter. For some time I could do nothing but gaze at the little patch of blue sky above me that seemed so hopelessly far away, as if rescue must soon come from thence. I could faintly hear poor Tiger’s barking still, and fearing he might go off in search of me, I kicked and pounded against the sides of the tree, shouting at the top of my voice. I don’t know whether he could hear me, but he did not go away at all events. It would have been far better for him, poor fellow, if he had. After some minutes the first bewildering paroxysm of fright abated, and I set myself seriously to consider what was to be done. I could not give up all hope of escape, desperate as my case seemed, and I felt sure I would lose my mind if I did not keep myself constantly employed in some way. There seemed but one thing to do, and to that I forthwith applied myself. In my belt hung my strong, keen-edged hunting-knife. Since I could not climb out of my prison, perhaps I could cut my way out. So drawing the knife, I set to work with tremendous vigour. At first it was easy enough, for the soft decayed wood offered little opposition to my keen blade, and I felt encouraged. But presently I reached the hard rind, and then had to go warily for fear of snapping the steel off short.
