Well, the ledge I reached was like this. It was some ten feet wide; it stuck out maybe six feet farther than the cliff top; the rock wall went up pretty near perpendicular, till near the coping at the ground; but below the ledge, the cliff’s face was so scooped away that the sea, five hundred feet below, ran in under it nigh fifty feet.
As I went down, thousands of birds rose from the jagged places of the precipice, circling around me with harsh screams. Soon touching the ledge, I stepped from the loop, and drawing down a little slack, walked off briskly. For fully a quarter of a mile the ledge ran along the cliff’s face almost as level and even in width as that sidewalk. I remember fancying that it sloped outward more than usual, but instantly dismissed the notion, though Gaffer Pentreath, the oldest man in that countryside, used to tell us that we should not get the use of that ledge always. It had been as steady in our time as in his grandfather’s, and we only laughed at his prophecies. Yet the place of an old filled fissure was marked by a line of grass, by tufts of weeds and small bushes, stretching almost as far as the ledge itself, and within a foot or so of the cliff’s face.
Eggs were not so many as usual, and I went a long piece from my rope before turning back. Then I noticed the very strange conduct of the hosts of sea-fowls below. Usually there were hundreds, but now there were millions on the wing, and instead of darting forth in playful motions, they seemed to be wildly excited, screaming shrilly, rushing out as in terror, and returning in masses as though to alight, only to wheel in dread and keep the air in vast clouds.
The weather was beautiful, the sea like glass. At no great distance were two large brigs and, nearer, a small yacht lay becalmed, heaving on the long billows. I could look down her cabin stairway almost, and it seemed scarcely more than a long leap to her deck.
Puzzled by the singular conduct of the sea-birds, I soon stopped and set my back against the cliff, to rest while watching them. The day was deadly still and very warm.
I remember taking off my cap and wiping the sweat from my face and forehead with my sleeve. While doing this, I looked down involuntarily to the fissure at my feet. Instantly my blood almost froze with horror! There was a distinct crack between the inner edge of the fissure and the hard-packed, root-threaded soil with which it was filled! Forcibly I pressed back, and in a flash looked along the ledge. The fissure was widening under my eyes, the rock before me seemed sinking outward, and with a shudder and a groan and roar, the whole long platform fell crashing to the sea below! I stood on a margin of rock scarce a foot wide, at my back a perpendicular cliff, and, five hundred feet below, the ocean, now almost hidden by the vast concourse of wheeling and affrighted birds.
