We found the entire length of the third chasm three hundred and twenty yards. At the point _a_ was an opening about six feet wide, and extending fifteen feet into the rock, where it terminated in a bed of marl, there being no other chasm beyond, as we had expected. We were about leaving this fissure, into which very little light was admitted, when Peters called my attention to a range of singular-looking indentures in the surface of the marl forming the termination of the _cul-de-sac_. With a very slight exertion of the imagination, the left, or most northern of these indentures might have been taken for the intentional, although rude, representation of a human figure standing erect, with outstretched arm. The rest of them bore also some little resemblance to alphabetical characters, and Peters was willing, at all events, to adopt the idle opinion that they were really such. I convinced him of his error, finally, by directing his attention to the floor of the fissure, where, among the powder, we picked up, piece by piece, several large flakes of the marl, which had evidently been broken off by some convulsion from the surface where the indentures were found, and which had projecting points exactly fitting the indentures; thus proving them to have been the work of nature. Figure 4 {image} presents an accurate copy of the whole.
After satisfying ourselves that these singular caverns afforded us no means of escape from our prison, we made our way back, dejected and dispirited, to the summit of the hill. Nothing worth mentioning occurred during the next twenty-four hours, except that, in examining the ground to the eastward of the third chasm, we found two triangular holes of great depth, and also with black granite sides. Into these holes we did not think it worth while to attempt descending, as they had the appearance of mere natural wells, without outlet. They were each about twenty yards in circumference, and their shape, as well as relative position in regard to the third chasm, is shown in figure 5. {image}
Chapter XXIV
0N the twentieth of the month, finding it altogether impossible to subsist any longer upon the filberts, the use of which occasioned us the most excruciating torment, we resolved to make a desperate attempt at descending the southern declivity of the hill. The face of the precipice was here of the softest species of soapstone, although nearly perpendicular throughout its whole extent (a depth of a hundred and fifty feet at the least), and in many places even overarching. After a long search we discovered a narrow ledge about twenty feet below the brink of the gulf; upon this Peters contrived to leap, with what assistance I could render him by means of our pocket-handkerchiefs tied together. With somewhat more difficulty I also got down; and we then saw the possibility of descending the whole way by the process in which we had clambered up from the chasm when we had been buried by the fall of the hill-that is, by cutting steps in the face of the soapstone with our knives. The extreme hazard of the attempt can scarcely be conceived; but, as there was no other resource, we determined to undertake it.
Upon the ledge where we stood there grew some filbert-bushes; and to one of these we made fast an end of our rope of handkerchiefs. The other end being tied round Peters' waist, I lowered him down over the edge of the precipice until the handkerchiefs were stretched tight. He now proceeded to dig a deep hole in the soapstone (as far in as eight or ten inches), sloping away the rock above to the height of a foot, or thereabout, so as to allow of his driving, with the butt of a pistol, a tolerably strong peg into the levelled surface. I then drew him up for about four feet, when he made a hole similar to the one below, driving in a peg as before, and having thus a resting-place for both feet and hands. I now unfastened the handkerchiefs from the bush, throwing him the end, which he tied to the peg in the uppermost hole, letting himself down gently to a station about three feet lower than he had yet been that is, to the full extent of the handkerchiefs. Here he dug another hole, and drove another peg. He then drew himself up, so as to rest his feet in the hole just cut, taking hold with his hands upon the peg in the one above. It was now necessary to untie the handkerchiefs from the topmost peg, with the view of fastening them to the second; and here he found that an error had been committed in cutting the holes at so great a distance apart. However, after one or two unsuccessful and dangerous attempts at reaching the knot (having to hold on with his left hand while he labored to undo the fastening with his right), he at length cut the string, leaving six inches of it affixed to the peg. Tying the handkerchiefs now to the second peg, he descended to a station below the third, taking care not to go too far down. By these means (means which I should never have conceived of myself, and for which we were indebted altogether to Peters' ingenuity and resolution) my companion finally succeeded, with the occasional aid of projections in the cliff, in reaching the bottom without accident.
It was some time before I could summon sufficient resolution to follow him; but I did at length attempt it. Peters had taken off his shirt before descending, and this, with my own, formed the rope necessary for the adventure. After throwing down the musket found in the chasm, I fastened this rope to the bushes, and let myself down rapidly, striving, by the vigor of my movements, to banish the trepidation which I could overcome in no other manner. This answered sufficiently well for the first four or five steps; but presently I found my imagination growing terribly excited by thoughts of the vast depths yet to be descended, and the precarious nature of the pegs and soapstone holes which were my only support. It was in vain I endeavored to banish these reflections, and to keep my eyes steadily bent upon the flat surface of the cliff before me. The more earnestly I struggled _not to think, _the more intensely vivid became my conceptions, and the more horribly distinct. At length arrived that crisis of fancy, so fearful in all similar cases, the crisis in which we began to anticipate the feelings with which we _shall _fall-to picture to ourselves the sickness, and dizziness, and the last struggle, and the half swoon, and the final bitterness of the rushing and headlong descent. And now I found these fancies creating their own realities, and all imagined horrors crowding upon me in fact. I felt my knees strike violently together, while my fingers were gradually but certainly relaxing their grasp. There was a ringing in my ears, and I said, "This is my knell of death!" And now I was consumed with the irrepressible desire of looking below. I could not, I would not, confine my glances to the cliff; and, with a wild, indefinable emotion, half of horror, half of a relieved oppression, I threw my vision far down into the abyss. For one moment my fingers clutched convulsively upon their hold, while, with the movement, the faintest possible idea of ultimate escape wandered, like a shadow, through my mind — in the next my whole soul was pervaded with a longing to fall; a desire, a yearning, a passion utterly uncontrollable. I let go at once my grasp upon the peg, and, turning half round from the precipice, remained tottering for an instant against its naked face. But now there came a spinning of the brain; a shrill-sounding and phantom voice screamed within my ears; a dusky, fiendish, and filmy figure stood immediately beneath me; and, sighing, I sunk down with a bursting heart, and plunged within its arms.
I had swooned, and Peters had caught me as I fell. He had observed my proceedings from his station at the bottom of the cliff; and perceiving my imminent danger, had endeavored to inspire me with courage by every suggestion he could devise; although my confusion of mind had been so great as to prevent my hearing what he said, or being conscious that he had even spoken to me at all. At length, seeing me totter, he hastened to ascend to my rescue, and arrived just in time for my preservation. Had I fallen with my full weight, the rope of linen would inevitably have snapped, and I should have been precipitated into the abyss; as it was, he contrived to let me down gently, so as to remain suspended without danger until animation returned. This was in about fifteen minutes. On recovery, my trepidation had entirely vanished; I felt a new being, and, with some little further aid from my companion, reached the bottom also in safety.
