The path, which had hitherto been considerably smooth, now became rugged and steep. Chilling damps, the secret trepidation which attended me, the length and difficulties of my way, enhanced by the ceaseless caution and the numerous expedients which the utter darkness obliged me to employ, began to overpower my strength. I was frequently compelled to stop and recruit myself by rest. These respites from toil were of use, but they could not enable me to prosecute an endless journey, and to return was scarcely a less arduous task than to proceed.

I looked anxiously forward, in the hope of being comforted by some dim ray, which might assure me that my labours were approaching an end. At last this propitious token appeared, and I issued forth into a kind of chamber, one side of which was open to the air and allowed me to catch a portion of the checkered sky. This spectacle never before excited such exquisite sensations in my bosom. The air, likewise, breathed into the cavern, was unspeakably delicious.

I now found myself on the projecture of a rock. Above and below, the hill-side was nearly perpendicular. Opposite, and at the distance of fifteen or twenty yards, was a similar ascent. At the bottom was a glen, cold, narrow, and obscure. This projecture, which served as a kind of vestibule to the cave, was connected with a ledge, by which, though not without peril and toil, I was conducted to the summit.

This summit was higher than any of those which were interposed between itself and the river. A large part of this chaos of rocks and precipices was subjected, at one view, to the eye. The fertile lawns and vales which lay beyond this, the winding course of the river, and the slopes which rose on its farther side, were parts of this extensive scene. These objects were at any time fitted to inspire rapture. Now my delight was enhanced by the contrast which this lightsome and serene element bore to the glooms from which I had lately emerged. My station, also, was higher, and the limits of my view, consequently, more ample than any which I had hitherto enjoyed.

I advanced to the outer verge of the hill, which I found to overlook a steep no less inaccessible, and a glen equally profound. I changed frequently my station in order to diversify the scenery. At length it became necessary to inquire by what means I should return. I traversed the edge of the hill, but on every side it was equally steep and always too lofty to permit me to leap from it. As I kept along the verge, I perceived that it tended in a circular direction, and brought me back, at last, to the spot from which I had set out. From this inspection, it seemed as if return was impossible by any other way than that through the cavern.

I now turned my attention to the interior space. If you imagine a cylindrical mass, with a cavity dug in the centre, whose edge conforms to the exterior edge; and if you place in this cavity another cylinder, higher than that which surrounds it, but so small as to leave between its sides and those of the cavity a hollow space, you will gain as distinct an image of this hill as words can convey. The summit of the inner rock was rugged and covered with trees of unequal growth. To reach this summit would not render my return easier; but its greater elevation would extend my view, and perhaps furnish a spot from which the whole horizon was conspicuous.

As I had traversed the outer, I now explored the inner, edge of this hill. At length I reached a spot where the chasm, separating the two rocks, was narrower than at any other part. At first view, it seemed as if it were possible to leap over it, but a nearer examination showed me that the passage was impracticable. So far as my eye could estimate it, the breadth was thirty or forty feet. I could scarcely venture to look beneath. The height was dizzy, and the walls, which approached each other at top, receded at the bottom, so as to form the resemblance of an immense hall, lighted from a rift which some convulsion of nature had made in the roof. Where I stood there ascended a perpetual mist, occasioned by a torrent that dashed along the rugged pavement below.

From these objects I willingly turned my eye upon those before and above me, on the opposite ascent. A stream, rushing from above, fell into a cavity, which its own force seemed gradually to have made. The noise and the motion equally attracted my attention. There was a desolate and solitary grandeur in the scene, enhanced by the circumstances in which it was beheld, and by the perils through which I had recently passed, that had never before been witnessed by me.

A sort of sanctity and awe environed it, owing to the consciousness of absolute and utter loneliness. It was probable that human feet had never before gained this recess, that human eyes had never been fixed upon these gushing waters. The aboriginal inhabitants had no motives to lead them into caves like this and ponder on the verge of such a precipice. Their successors were still less likely to have wandered hither. Since the birth of this continent, I was probably the first who had deviated thus remotely from the customary paths of men.

While musing upon these ideas, my eye was fixed upon the foaming current. At length I looked upon the rocks which confined and embarrassed its course. I admired their fantastic shapes and endless irregularities. Passing from one to the other of these, my attention lighted, at length, as if by some magical transition, on--a human countenance!
