Chapter XXVI: The Work of the Sea
The lift of the water-spout had saved John Rex's life. At the moment
when it struck him he was on his hands and knees at the entrance of the cavern. The wave, gushing upwards, at the same time expanded, laterally, and this lateral force drove the convict into the mouth of the subterranean passage. The passage trended downwards, and for some seconds he was rolled over and over, the rush of water wedging him at length into a crevice between two enormous stones, which overhung a still more formidable abyss. Fortunately for the preservation of his hard-fought-for life, this very fury of incoming water prevented him from being washed out again with the recoil of the wave. He could hear the water dashing with frightful echoes far down into the depths beyond him, but it was evident that the two stones against which he had been thrust acted as breakwaters to the torrent poured in from the outside, and repelled the main body of the stream in the fashion he had observed from his position on the ledge. In a few seconds the cavern was empty.
Painfully extricating himself, and feeling as yet doubtful of his safety, John Rex essayed to climb the twin-blocks that barred the unknown depths below him. The first movement he made caused him to shriek aloud. His left arm—with which he clung to the rope—hung powerless. Ground against the ragged entrance, it was momentarily paralysed. For an instant the unfortunate wretch sank despairingly on the wet and rugged floor of the cave; then a terrible gurgling beneath his feet warned him of the approaching torrent, and, collecting all his energies, he scrambled up the incline. Though nigh fainting with pain and exhaustion, he pressed desperately higher and higher. He heard the hideous shriek of the whirlpool which was beneath him grow louder and louder. He saw the darkness grow darker as the rising water-spout covered the mouth of the cave. He felt the salt spray sting his face, and the wrathful tide lick the hand that hung over the shelf on which he fell. But that was all. He was out of danger at last! And as the thought blessed his senses, his eyes closed, and the wonderful courage and strength which had sustained the villain so long exhaled in stupor.
When he awoke the cavern was filled with the soft light of dawn. Raising his eyes, he beheld, high above his head, a roof of rock, on which the reflection of the sunbeams, playing upwards through a pool of water, cast flickering colours. On his right hand was the mouth of the cave, on his left a terrific abyss, at the bottom of which he could hear the sea faintly lapping and washing. He raised himself and stretched his stiffened limbs. Despite his injured shoulder, it was imperative that he should bestir himself. He knew not if his escape had been noticed, or if the cavern had another inlet, by which McNab, returning, might penetrate. Moreover, he was wet and famished. To preserve the life which he had torn from the sea, he must have fire and food. First he examined the crevice by which he had entered. It was shaped like an irregular triangle, hollowed at the base by the action of the water which in such storms as that of the preceding night was forced into it by the rising of the sea. John Rex dared not crawl too near the edge, lest he should slide out of the damp and slippery orifice, and be dashed upon the rocks at the bottom of the Blow-hole. Craning his neck, he could see, a hundred feet below him, the sullenly frothing water, gurgling, spouting, and creaming, in huge turbid eddies, occasionally leaping upwards as though it longed for another storm to send it raging up to the man who had escaped its fury. It was impossible to get down that way. He turned back into the cavern, and began to explore in that direction.
