Thrusting myself to the edge of the precipice, I peered below. Nothing rewarded my gaze except horrifying silence and vapory gloom. The pain of the movement was so intense that I fell back almost in a swoon.

Before long, however, I saw that the moon was drawing near the rim of the gorge and that I would soon be engulfed in utter darkness, so I turned my eyes up the jagged wall in search of some means of escape. After considerable study, I thought I could discern a way to the summit.

But just then another surprise caught my gaze: the strip of sky above the chasm appeared narrower than when I had first turned my eyes upward. For a few moments I attributed this to an optical illusion produced by some swiftly-moving clouds overhead; but all at once the hideous truth burst upon me—the crack in the earth was drawing shut!

Heedless of the pain, I flung myself against the cliff—climbing in utter panic, for fear the chasm would close completely before I could get out.

The ascent was difficult and perilous in the extreme. Often rocks loosened beneath my fingers, starting miniature avalanches, and I flattened myself against the wall in a paroxysm of terror and clung there until the danger passed.

For a space that seemed hours long I continued to claw my way upward—with the prodigious trap closing steadily upon me. At times I found myself below unscalable surfaces, and was obliged to descend a bit and start over again in a new direction; and often it seemed as if the pain of my injuries would cause me to faint.

When I had come within thirty feet of the top, the climb developed into a veritable race with death, for the opposite wall was now almost upon me.

And then, suddenly, I found the way blocked by a sheer, unscalable wall, upon which only a fly could have found a foothold! Simultaneously I saw that the moon was right at the rim of the chasm, and that in a minute the light would vanish.

With the realization of my plight, panic seized me, and I beat my head against the wall and shrieked aloud.

And, though I could not guess it then, that very outcry of despair was to save my life.
