I was now assailed by the torments of thirst. My invention and my courage were anew bent to obviate this pressing evil. I reflected that there was some recess from this cavern, even from the spot where I now stood. Before, I was doubtful whether in this direction from this pit any avenue could be found; but, since the panther had come hither, there was reason to suppose the existence of some such avenue.
I now likewise attended to a sound, which, from its invariable tenor, denoted somewhat different from the whistling of a gale. It seemed like the murmur of a running stream. I now prepared to go forward and endeavour to move along in that direction in which this sound apparently came.
On either side, and above my head, there was nothing but vacuity. My steps were to be guided by the pavement, which, though unequal and rugged, appeared, on the whole, to ascend. My safety required that I should employ both hands and feet in exploring my way.
I went on thus for a considerable period. The murmur, instead of becoming more distinct, gradually died away. My progress was arrested by fatigue, and I began once more to despond. My exertions produced a perspiration, which, while it augmented my thirst, happily supplied me with imperfect means of appeasing it.
This expedient would, perhaps, have been accidentally suggested; but my ingenuity was assisted by remembering the history of certain English prisoners in Bengal, whom their merciless enemy imprisoned in a small room, and some of whom preserved themselves alive merely by swallowing the moisture that flowed from their bodies. This experiment I now performed with no less success.
This was slender arid transitory consolation. I knew that, wandering at random, I might never reach the outlet of this cavern, or might be disabled, by hunger and fatigue, from going farther than the outlet. The cravings which had lately been satiated would speedily return, and my negligence had cut me off from the resource which had recently been furnished. I thought not till now that a second meal might be indispensable.
To return upon my footsteps to the spot where the dead animal lay was a heartless project. I might thus be placing myself at a hopeless distance from liberty. Besides, my track could not be retraced. I had frequently deviated from a straight direction for the sake of avoiding impediments. All of which I was sensible was, that I was travelling up an irregular acclivity. I hoped some time to reach the summit, but had no reason for adhering to one line of ascent in preference to another.
To remain where I was was manifestly absurd. Whether I mounted or descended, a change of place was most likely to benefit me. I resolved to vary my direction, and, instead of ascending, keep along the side of what I accounted a hill. I had gone some hundred feet when the murmur, before described, once more saluted my ear.
This sound, being imagined to proceed from a running stream, could not but light up joy in the heart of one nearly perishing with thirst. I proceeded with new courage. The sound approached no nearer, nor became more distinct; but, as long as it died not away, I was satisfied to listen and to hope.
I was eagerly observant if any the least glimmering of light should visit this recess. At length, on the right hand, a gleam, infinitely faint, caught my attention. It was wavering and unequal. I directed my steps towards it. It became more vivid and permanent. It was of that kind, however, which proceeded from a fire, kindled with dry sticks, and not from the sun. I now heard the crackling of flames.
