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. The twin-rocks against which he had been hurled were, in fact, pillars which supported the roof of the water-drive. Beyond them lay a great grey shadow which was emptiness, faintly illumined by the sea-light cast up through the bottom of the gulf. Midway across the grey shadow fell a strange beam of dusky brilliance, which cast its flickering light upon a wilderness of waving sea-weeds. Even in the desperate position in which he found himself, there survived in the vagabond's nature sufficient poetry to make him value the natural marvel upon which he had so strangely stumbled. The immense promontory, which, viewed from the outside, seemed as solid as a mountain, was in reality but a hollow cone, reft and split into a thousand fissures by the unsuspected action of the sea for centuries. The Blow-hole was but an insignificant cranny compared with this enormous chasm. Descending with difficulty the steep incline, he found himself on the brink of a gallery of rock, which, jutting out over the pool, bore on its moist and weed-bearded edges signs of frequent submersion. It must be low tide without the rock. Clinging to the rough and root-like algae that fringed the ever-moist walls, John Rex crept round the projection of the gallery, and passed at once from dimness to daylight. There was a broad loop-hole in the side of the honey-combed and wave-perforated cliff. The cloudless heaven expanded above him; a fresh breeze kissed his cheek and, sixty feet below him, the sea wrinkled all its lazy length, sparkling in myriad wavelets beneath the bright beams of morning. Not a sign of the recent tempest marred the exquisite harmony of the picture. Not a sign of human life gave evidence of the grim neighbourhood of the prison. From the recess out of which he peered nothing was visible but a sky of turquoise smiling upon a sea of sapphire.
The placidity of Nature was, however, to the hunted convict a new source of alarm. It was a reason why the Blow-hole and its neighbourhood should be thoroughly searched. He guessed that the favourable weather would be an additional inducement to McNab and Burgess to satisfy themselves as to the fate of their late prisoner. He turned from the opening, and prepared to descend still farther into the rock pathway. The sunshine had revived and cheered him, and a sort of instinct told him that the cliff, so honey-combed above, could not be without some gully or chink at its base, which at low tide would give upon the rocky shore. It grew darker as he descended, and twice he almost turned back in dread of the gulfs on either side of him. It seemed to him, also, that the gullet of weed-clad rock through which he was crawling doubled upon itself, and led only into the bowels of the mountain. Gnawed by hunger, and conscious that in a few hours at most the rising tide would fill the subterranean passage and cut off his retreat, he pushed desperately onwards. He had descended some ninety feet, and had lost, in the devious windings of his downward path, all but the reflection of the light from the gallery, when he was rewarded by a glimpse of sunshine striking upwards. He parted two enormous masses of seaweed, whose bubble-headed fronds hung curtainwise across his path, and found himself in the very middle of the narrow cleft of rock through which the sea was driven to the Blow-hole.
At an immense distance above him was the arch of cliff. Beyond that arch appeared a segment of the ragged edge of the circular opening, down which he had fallen. He looked in vain for the funnel-mouth whose friendly shelter had received him. It was now indistinguishable. At his feet was a long rift in the solid rock, so narrow that he could almost have leapt across it. This rift was the channel of a swift black current which ran from the sea for fifty yards under an arch eight feet high, until it broke upon the jagged rocks that lay blistering in the sunshine at the bottom of the circular opening in the upper cliff. A shudder shook the limbs of the adventurous convict. He comprehended that at high tide the place where he stood was under water, and that the narrow cavern became a subaqueous pipe of solid rock forty feet long, through which were spouted the league-long rollers of the Southern Sea.
The narrow strip of rock at the base of the cliff was as flat as a table. Here and there were enormous hollows like pans, which the retreating tide had left full of clear, still water. The crannies of the rock were inhabited by small white crabs, and John Rex found to his delight that there was on this little shelf abundance of mussels, which, though lean and acrid, were sufficiently grateful to his famished stomach. Attached to the flat surfaces of the numerous stones, moreover, were coarse limpets. These, however, John Rex found too salt to be palatable, and was compelled to reject them. A larger variety, however, having a succulent body as thick as a man's thumb, contained in long razor-shaped shells, were in some degree free from this objection, and he soon collected the materials for a meal. Having eaten and sunned himself, he began to examine the enormous rock, to the base of which he had so strangely penetrated. Rugged and worn, it raised its huge breast against wind and wave, secure upon a broad pedestal, which probably extended as far beneath the sea as the massive column itself rose above it. Rising thus, with its shaggy drapery of seaweed clinging about its knees, it seemed to be a motionless but sentient being--some monster of the deep, a Titan of the ocean condemned ever to front in silence the fury of that illimitable and rarely-travelled sea. Yet--silent and motionless as he was--the hoary ancient gave hint of the mysteries of his revenge. Standing upon the broad and sea-girt platform where surely no human foot but his had ever stood in life, the convict saw, many feet above him, pitched into a cavity of the huge sun-blistered boulders, an object which his sailor eye told him at once was part of the top hamper of some large ship. Crusted with shells, and its ruin so overrun with the ivy of the ocean that its ropes could barely be distinguished from the weeds with which they were encumbered, this relic of human labour attested the triumph of nature over human ingenuity. Perforated below by the relentless sea, exposed above to the full fury of the tempest; set in solitary defiance to the waves, that rolling from the ice-volcano of the Southern Pole, hurled their gathered might unchecked upon its iron front, the great rock drew from its lonely warfare the materials of its own silent vengeance. Clasped in iron arms, it held its prey, snatched from the jaws of the all-devouring sea. One might imagine that, when the doomed ship, with her crew of shrieking souls, had splintered and gone down, the deaf, blind giant had clutched this fragment, upheaved from the seething waters, with a thrill of savage and terrible joy.
John Rex, gazing up at this memento of a forgotten agony, felt a sensation of the most vulgar pleasure. "There's wood for my fire!" thought he; and mounting to the spot, he essayed to fling down the splinters of timber upon the platform. Long exposed to the sun, and flung high above the water-mark of recent storms, the timber had dried to the condition of touchwood, and would burn fiercely. It was precisely what he required. Strange accident that had for years stored, upon a desolate rock, this fragment of a vanished and long-forgotten vessel, that it might aid at last to warm the limbs of a villain escaping from justice!
Striking the disintegrated mass with his iron-shod heel, John Rex broke off convenient portions; and making a bag of his shirt by tying the sleeves and neck, he was speedily staggering into the cavern with a supply of fuel. He made two trips, flinging down the wood on the floor of the gallery that overlooked the sea, and was returning for a third, when his quick ear caught the dip of oars. He had barely time to lift the seaweed curtain that veiled the entrance to the chasm, when the Eaglehawk boat rounded the promontory. Burgess was in the stern-sheets, and seemed to be making signals to someone on the top of the cliff. Rex, grinning behind his veil, divined the manoeuvre. McNab and his party were to search above, while the Commandant examined the gulf below. The boat headed direct for the passage, and for an instant John Rex's undaunted soul shivered at the thought that, perhaps, after all, his pursuers might be aware of the existence of the cavern. Yet that was unlikely. He kept his ground, and the boat passed within a foot of him, gliding silently into the gulf. He observed that Burgess's usually florid face was pale, and that his left sleeve was cut open, showing a bandage on the arm. There had been some fighting, then, and it was not unlikely that all his fellow-desperadoes had been captured! He chuckled at his own ingenuity and good sense. The boat, emerging from the archway, entered the pool of the Blow-hole, and, held with the full strength of the party, remained stationary. John Rex watched Burgess scan the rocks and eddies, saw him signal to McNab, and then, with much relief, beheld the boat's head brought round to the sea-board.
He was so intent upon watching this dangerous and difficult operation that he was oblivious of an extraordinary change which had taken place in the interior of the cavern. The water which, an hour ago, had left exposed a long reef of black hummock-rocks, was now spread in one foam-flecked sheet over the ragged bottom of the rude staircase by which he had descended. The tide had turned, and the sea, apparently sucked in through some deeper tunnel in the portion of the cliff which was below water, was being forced into the vault with a rapidity which bid fair to shortly submerge the mouth of the cave. The convict's feet were already wetted by the incoming waves, and as he turned for one last look at the boat he saw a green billow heave up against the entrance to the chasm, and, almost blotting out the daylight, roll majestically through the arch. It was high time for Burgess to take his departure if he did not wish his whale-boat to be cracked like a nut against the roof of the tunnel. Alive to his danger, the Commandant abandoned the search after his late prisoner's corpse, and he hastened to gain the open sea. The boat, carried backwards and upwards on the bosom of a monstrous wave, narrowly escaped destruction, and John Rex, climbing to the gallery, saw with much satisfaction the broad back of his out-witted gaoler disappear round the sheltering promontory. The last efforts of his pursuers had failed, and in another hour the only accessible entrance to the convict's retreat was hidden under three feet of furious seawater.
His gaolers were convinced of his death, and would search for him no more. So far, so good. Now for the last desperate venture--the escape from the wonderful cavern which was at once his shelter and his prison. Piling his wood together, and succeeding after many efforts, by the aid of a flint and the ring which yet clung to his ankle, in lighting a fire, and warming his chilled limbs in its cheering blaze, he set himself to meditate upon his course of action. He was safe for the present, and the supply of food that the rock afforded was amply sufficient to sustain life in him for many days, but it was impossible that he could remain for many days concealed. He had no fresh water, and though, by reason of the soaking he had received, he had hitherto felt little inconvenience from this cause, the salt and acrid mussels speedily induced a raging thirst, which he could not alleviate. It was imperative that within forty-eight hours at farthest he should be on his way to the peninsula. He remembered the little stream into which--in his flight of the previous night-- he had so nearly fallen, and hoped to be able, under cover of the darkness, to steal round the reef and reach it unobserved. His desperate scheme was then to commence. He had to run the gauntlet of the dogs and guards, gain the peninsula, and await the rescuing vessel. He confessed to himself that the chances were terribly against him. If Gabbett and the others had been recaptured--as he devoutly trusted--the coast would be comparatively clear; but if they had escaped, he knew Burgess too well to think that he would give up the chase while hope of re-taking the absconders remained to him. If indeed all fell out as he had wished, he had still to sustain life until Blunt found him--if haply Blunt had not returned, wearied with useless and dangerous waiting.
As night came on, and the firelight showed strange shadows waving from the corners of the enormous vault, while the dismal abysses beneath him murmured and muttered with uncouth and ghastly utterance, there fell upon the lonely man the terror of Solitude. Was this marvellous hiding-place that he had discovered to be his sepulchre? Was he--a monster amongst his fellow-men--to die some monstrous death, entombed in this mysterious and terrible cavern of the sea? He had tried to drive away these gloomy thoughts by sketching out for himself a plan of action-- but in vain. In vain he strove to picture in its completeness that --as yet vague--design by which he promised himself to wrest from the vanished son of the wealthy ship-builder his name and heritage. His mind, filled with forebodings of shadowy horror, could not give the subject the calm consideration which it needed. In the midst of his schemes for the baffling of the jealous love of the woman who was to save him, and the getting to England, in shipwrecked and foreign guise, as the long-lost heir to the fortune of Sir Richard Devine, there arose ghastly and awesome shapes of death and horror, with whose terrible unsubstantiality he must grapple in the lonely recesses of that dismal cavern. He heaped fresh wood upon his fire, that the bright light might drive out the gruesome things that lurked above, below, and around him. He became afraid to look behind him, lest some shapeless mass of mid-sea birth--some voracious polype, with far-reaching arms and jellied mouth ever open to devour--might slide up over the edge of the dripping caves below, and fasten upon him in the darkness. His imagination--always sufficiently vivid, and spurred to an unnatural effect by the exciting scenes of the previous night--painted each patch of shadow, clinging bat-like to the humid wall, as some globular sea-spider ready to drop upon him with its viscid and clay-cold body, and drain out his chilled blood, enfolding him in rough and hairy arms. Each splash in the water beneath him, each sigh of the multitudinous and melancholy sea, seemed to prelude the laborious advent of some mis-shapen and ungainly abortion of the ooze. All the sensations induced by lapping water and regurgitating waves took material shape and surrounded him. All creatures that could be engendered by slime and salt crept forth into the firelight to stare at him. Red dabs and splashes that were living beings, having a strange phosphoric light of their own, glowed upon the floor. The livid encrustations of a hundred years of humidity slipped from off the walls and painfully heaved their mushroom surfaces to the blaze. The red glow of the unwonted fire, crimsoning the wet sides of the cavern, seemed to attract countless blisterous and transparent shapelessnesses, which elongated themselves towards him. Bloodless and bladdery things ran hither and thither noiselessly. Strange carapaces crawled from out of the rocks. All the horrible unseen life of the ocean seemed to be rising up and surrounding him. He retreated to the brink of the gulf, and the glare of the upheld brand fell upon a rounded hummock, whose coronal of silky weed out-floating in the water looked like the head of a drowned man. He rushed to the entrance of the gallery, and his shadow, thrown into the opening, took the shape of an avenging phantom, with arms upraised to warn him back. The naturalist, the explorer, or the shipwrecked seaman would have found nothing frightful in this exhibition of the harmless life of the Australian ocean. But the convict's guilty conscience, long suppressed and derided, asserted itself in this hour when it was alone with Nature and Night. The bitter intellectual power which had so long supported him succumbed beneath imagination--the unconscious religion of the soul. If ever he was nigh repentance it was then. Phantoms of his past crimes gibbered at him, and covering his eyes with his hands, he fell shuddering upon his knees. The brand, loosening from his grasp, dropped into the gulf, and was extinguished with a hissing noise. As if the sound had called up some spirit that lurked below, a whisper ran through the cavern.
"John Rex!" The hair on the convict's flesh stood up, and he cowered to the earth.
It was a human voice! Whether of friend or enemy he did not pause to think. His terror over-mastered all other considerations.
"Here! here!" he cried, and sprang to the opening of the vault.
Arrived at the foot of the cliff, Blunt and Staples found themselves in almost complete darkness, for the light of the mysterious fire, which had hitherto guided them, had necessarily disappeared. Calm as was the night, and still as was the ocean, the sea yet ran with silent but dangerous strength through the channel which led to the Blow-hole; and Blunt, instinctively feeling the boat drawn towards some unknown peril, held off the shelf of rocks out of reach of the current. A sudden flash of fire, as from a flourished brand, burst out above them, and floating downwards through the darkness, in erratic circles, came an atom of burning wood. Surely no one but a hunted man would lurk in such a savage retreat.
Blunt, in desperate anxiety, determined to risk all upon one venture. "John Rex!" he shouted up through his rounded hands. The light flashed again at the eye-hole of the mountain, and on the point above them appeared a wild figure, holding in its hands a burning log, whose fierce glow illumined a face so contorted by deadly fear and agony of expectation that it was scarce human.
"The poor devil seems half-crazy," said Will Staples, under his breath; and then aloud, "We're FRIENDS!" A few moments sufficed to explain matters. The terrors which had oppressed John Rex disappeared in human presence, and the villain's coolness returned. Kneeling on the rock platform, he held parley.
"It is impossible for me to come down now," he said. "The tide covers the only way out of the cavern."
"Can't you dive through it?" said Will Staples.
"No, nor you neither," said Rex, shuddering at the thought of trusting himself to that horrible whirlpool.
"What's to be done? You can't come down that wall." "Wait until morning," returned Rex coolly. "It will be dead low tide at seven o'clock. You must send a boat at six, or there-abouts. It will be low enough for me to get out, I dare say, by that time."
"But the Guard?"
" Won't come here, my man. They've got their work to do in watching the Neck and exploring after my mates. They won't come here. Besides, I'm dead."
"Thought to be so, which is as well--better for me, perhaps. If they don't see your ship, or your boat, you're safe enough."
"I don't like to risk it," said Blunt. "It's Life if we're caught."
"It's Death if I'm caught!" returned the other, with a sinister laugh. "But there's no danger if you are cautious. No one looks for rats in a terrier's kennel, and there's not a station along the beach from here to Cape Pillar. Take your vessel out of eye-shot of the Neck, bring the boat up Descent Beach, and the thing's done."
"Well," says Blunt, "I'll try it."
"You wouldn't like to stop here till morning? It is rather lonely," suggested Rex, absolutely making a jest of his late terrors.
Will Staples laughed. "You're a bold boy!" said he. "We'll come at daybreak."
"Have you got the clothes as I directed?"
"Then good night. I'll put my fire out, in case somebody else might see it, who wouldn't be as kind as you are."
"Not a word for the Madam," said Staples, when they reached the vessel.
"Not a word, the ungrateful dog," asserted Blunt, adding, with some heat, "That's the way with women. They'll go through fire and water for a man that doesn't care a snap of his fingers for 'em; but for any poor fellow who risks his neck to pleasure 'em they've nothing but sneers! I wish I'd never meddled in the business."
"There are no fools like old fools," thought Will Staples, looking back through the darkness at the place where the fire had been, but he did not utter his thoughts aloud.
At eight o'clock the next morning the Pretty Mary stood out to sea with every stitch of canvas set, alow and aloft. The skipper's fishing had come to an end. He had caught a shipwrecked seaman, who had been brought on board at daylight, and was then at breakfast in the cabin. The crew winked at each other when the haggard mariner, attired in garments that seemed remarkably well preserved, mounted the side. But they, none of them, were in a position to controvert the skipper's statement.
"Where are we bound for?" asked John Rex, smoking Staples's pipe in lingering puffs of delight. "I'm entirely in your hands, Blunt."
"My orders are to cruise about the whaling grounds until I meet my consort," returned Blunt sullenly, "and put you aboard her. She'll take you back to Sydney. I'm victualled for a twelve-months' trip."
"Right!" cried Rex, clapping his preserver on the back. "I'm bound to get to Sydney somehow; but, as the Philistines are abroad, I may as well tarry in Jericho till my beard be grown. Don't stare at my Scriptural quotation, Mr. Staples," he added, inspirited by creature comforts, and secure amid his purchased friends. "I assure you that I've had the very best religious instruction. Indeed, it is chiefly owing to my worthy spiritual pastor and master that I am enabled to smoke this very villainous tobacco of yours at the present moment!"
