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.

The close confinement, the heavy, poisonous air, and the constrained position the work required, all told hard upon me; but I toiled away with the determination of despair.

I must have spent at least an hour thus, when, to my delight, a hard blow sent the knife-blade clean through the wood, and on drawing it back a blessed little bit of daylight peeped through, which made a new man of me.

At it I went again, and paused not this time until I had a jagged hole chipped out through which I could put my hand. If the bear did not come for a couple of hours more I would be free.
