With the coming of daylight his growing terror added wings to his thought, and he achieved a new and profoundly simple theory of escape. Since he could not climb up, and since he could not get out through the sides themselves, then the only possible remaining way was down. Fool that he was! He might have been working through the cool night hours, and now he must labour in the quickly increasing heat. He applied himself in an ecstasy of energy to digging down through the mass of crumbling bones. Of course, there was a way out. Else how did the funnel drain? Otherwise it would have been full or part full of water from the rains. Fool! And thrice times thrice a fool!
He dug down one side of the wall, flinging the rubbish into a mound against the opposite side. So desperately did he apply himself that he broke his finger-nails to the quick and deeper, while every finger-tip was lacerated to bleeding. But love of life was strong in him, and he knew it was a life-and-death race with the sun. As he went deeper, the rubbish became more compact, so that he used the muzzle of his rifle like a crowbar to loosen it, ere tossing it up in single and double handfuls.
By mid-forenoon, his senses beginning to reel in the heat, he made a discovery. Upon the wall which he had uncovered, he came upon the beginning of an inscription, evidently rudely scratched in the rock by the point of a knife. With renewed hope, his head and shoulders down in the hole, he dug and scratched for all the world like a dog, throwing the rubbish out and between his legs in true dog-fashion. Some of it fell clear, but most of it fell back and down upon him. Yet had he become too frantic to note the inefficiency of his effort.
At last the inscription was cleared, so that he was able to read:
Peter McGill, of Glasgow. On March 12, 1820,
I escaped from the Pit of Hell by this passage by
digging down and finding it.
A passage! The passage must be beneath the inscription! Torres now toiled in a fury. So dirt-soiled was he that he was like some huge, four-legged, earth-burrowing animal. The dirt got into his eyes, and, on occasion, into his nostrils and air passages so as to suffocate him and compel him to back up out of the hole and sneeze and cough his breathing apparatus clear. Twice he fainted. But the sun, by then almost directly overhead, drove him on.
He found the upper rim of the passage. He did not dig down to the lower rim; for the moment the aperture was large enough to accommodate his lean shape, he writhed and squirmed into it and away from the destroying sun-rays. The cool and the dark soothed him, but his joy and the reaction from what he had undergone sent his pulse giddily up, so that for the third time he fainted.
Recovered, mouthing with black and swollen lips a half-insane chant of gratefulness and thanksgiving, he crawled on along the passage. Perforce he crawled, because it was so low that a dwarf could not have stood erect in it. The place was a charnel house. Bones crunched and crumbled under his hands and knees, and he knew that his knees were being worn to the bone. At the end of a hundred feet he caught his first glimmering of light. But the nearer he approached freedom, the slower he progressed, for the final stages of exhaustion were coming upon him. He knew that it was not physical exhaustion, nor food exhaustion, but thirst exhaustion. Water, a few ounces of water, was all he needed to make him strong again. And there was no water.
