The roaring column mounted with hideous swiftness. Rex felt it rush at him and swing him upward. With both arms round the tree, he clutched the sleeves of his jacket with either hand. Perhaps if he could maintain his hold he might outlive the shock of that suffocating torrent. He felt his feet rudely seized, as though by the hand of a giant, and plucked upwards. Water gurgled in his ears. His arms seemed about to be torn from their sockets. Had the strain lasted another instant, he must have loosed his hold; but, with a wild hoarse shriek, as though it was some sea-monster baffled of its prey, the column sank, and left him gasping, bleeding, half-drowned, but alive. It was impossible that he could survive another shock, and in his agony he unclasped his stiffened fingers, determined to resign himself to his fate. At that instant, however, he saw on the wall of rock that hollowed on his right hand, a red and lurid light, in the midst of which fantastically bobbed hither and thither the gigantic shadow of a man. He cast his eyes upwards and saw, slowly descending into the gulf, a blazing bush tied to a rope. McNab was taking advantage of the pause in the spouting to examine the sides of the Blow-hole.
A despairing hope seized John Rex. In another instant the light would reveal his figure, clinging like a limpet to the rock, to those above. He must be detected in any case; but if they could lower the rope sufficiently, he might clutch it and be saved. His dread of the horrible death that was beneath him overcame his resolution to avoid recapture. The long-drawn agony of the retreating water as it was sucked back again into the throat of the chasm had ceased, and he knew that the next tremendous pulsation of the sea below would hurl the spuming destruction up upon him. The gigantic torch slowly descended, and he had already drawn in his breath for a shout which should make itself heard above the roar of the wind and water, when a strange appearance on the face of the cliff made him pause. About six feet from him—glowing like molten gold in the gusty glow of the burning tree—a round sleek stream of water slipped from the rock into the darkness, like a serpent from its hole. Above this stream a dark spot defied the torchlight, and John Rex felt his heart leap with one last desperate hope as he comprehended that close to him was one of those tortuous drives which the worm-like action of the sea bores in such caverns as that in which he found himself. The drive, opened first to the light of the day by the natural convulsion which had raised the mountain itself above ocean level, probably extended into the bowels of the cliff. The stream ceased to let itself out of the crevice; it was then likely that the rising column of water did not penetrate far into this wonderful hiding-place.
Endowed with a wisdom, which in one placed in less desperate position would have been madness, John Rex shouted to his pursuers. “The rope! the rope!” The words, projected against the sides of the enormous funnel, were pitched high above the blast, and, reduplicated by a thousand echoes, reached the ears of those above.
“He's alive!” cried McNab, peering into the abyss. “I see him. Look!”
The soldier whipped the end of the bullock-hide lariat round the tree to which he held, and began to oscillate it, so that the blazing bush might reach the ledge on which the daring convict sustained himself. The groan which preceded the fierce belching forth of the torrent was cast up to them from below.
“God be gude to the puir felly!” said the pious young Scotchman, catching his breath.
A white spume was visible at the bottom of the gulf, and the groan changed into a rapidly increasing bellow. John Rex, eyeing the blazing pendulum, that with longer and longer swing momentarily neared him, looked up to the black heaven for the last time with a muttered prayer. The bush—the flame fanned by the motion—flung a crimson glow upon his frowning features which, as he caught the rope, had a sneer of triumph on them. “Slack out! slack out!” he cried; and then, drawing the burning bush towards him, attempted to stamp out the fire with his feet.
The soldier set his body against the tree trunk, and gripped the rope hard, turning his head away from the fiery pit below him. “Hold tight, your honour,” he muttered to McNab. “She's coming!”
The bellow changed into a roar, the roar into a shriek, and with a gust of wind and spray, the seething sea leapt up out of the gulf. John Rex, unable to extinguish the flame, twisted his arm about the rope, and the instant before the surface of the rising water made a momentary floor to the mouth of the cavern, he spurned the cliff desperately with his feet, and flung himself across the chasm. He had already clutched the rock, and thrust himself forward, when the tremendous volume of water struck him. McNab and the soldier felt the sudden pluck of the rope and saw the light swing across the abyss. Then the fury of the waterspout burst with a triumphant scream, the tension ceased, the light was blotted out, and when the column sank, there dangled at the end of the lariat nothing but the drenched and blackened skeleton of the she-oak bough. Amid a terrific peal of thunder, the long pent-up rain descended, and a sudden ghastly rending asunder of the clouds showed far below them the heaving ocean, high above them the jagged and glistening rocks, and at their feet the black and murderous abyss of the Blowhole—empty.
They pulled up the useless rope in silence; and another dead tree lighted and lowered showed them nothing.
