"Which it aren't, sir, for I've done it."

The burning pieces of wood increased in number now, lighting up the huge cavern weirdly, and the blacks were not a hundred yards away, and approaching cautiously.

"What do you say, Panton--fight or run that horrible risk and retreat?"

"I'd say fight," replied Panton, with a shudder, "but we should not beat them off. They'd never dare to follow here. Let's try it. Wriggs got through, why should not we?"

"Yes, go on," cried Oliver. "You cannot talk to the men, and it's as well they do not know the danger. Lead on, Wriggs, and Heaven help us all."

It was as he said, no one but Smith fully realised what the dangers were, and though they were staggered by the noise and horrors around them, the men knew that there was a way through, and, following their comrade's example, they lowered themselves down over the edge of the rock and dropped, the stream seeming less repellent than the ferocious enemy.

One by one they dropped down, disappearing directly as if suddenly s.n.a.t.c.hed away, till only Smith was left with the three friends, and his action was suggestive, for he held out his hand to each in turn, shook that placed within it, and then, grasping his gun, lowered himself over the edge.

The blacks were very near as Drew followed the man's example, and then Panton shook hands with Oliver.

"Good-bye, or _au revoir_," he cried, and turning, he jumped boldly forward into the darkness.

A loud yell arose now, for the lights showed Oliver standing on the brink, and, lowering their spears, a dozen savages rushed at him, but he stepped off the rock edge, descended quickly for some distance, and then plunged into the rushing water, which seemed to rise at him, seize him, and bear him along at a rapidly increasing rate, but with his head above the surface, and the echoing roar of falling waters striking his ears with stunning violence. Then he felt himself suddenly shot out as it were into s.p.a.ce, suffocated by the rushing torrent, which poured down upon him, and faint, bewildered, and exhausted, whirled round, and beaten down here and there. At last his face was above the surface, and he was being borne rapidly along a shallow stream, just as Wriggs had described, with its smooth, gla.s.sy bottom.

Hope sprang up within his breast once more, for he could breathe again at such times as he could get his head above the rapids; what was more, he could fight for his life against an enemy more merciful than the cascade over which he had been dashed.

But it was a terrible struggle for breath in the darkness of the vast tunnel through which he was being hurried, and though from time to time he touched smooth, water-worn rock, he could get no hold.

At length, after how long he could not tell, he became conscious that the now swift, smooth stream was growing shallower, and recalling the sailor's words, after many efforts he managed to gain and retain his feet, wading onward, and sufficiently recovered to listen for the sound of pursuit, of which there was none.

The noise, too, was dying out. There was a deep, murmuring roar, and the low, whispering rush, but that was all.

And now the confusion in Oliver's brain seemed to clear off. His efforts to preserve life so far had been instinctive; from this moment there was more method. He began as he groped along to make use of the gun to which he still clung, as a staff, but he had not taken many steps onward in the way the water pressed and which he knew must be toward daylight when self was forgotten, and the thought of his comrades made him feel ready to sink helplessly once more and let the stream carry him where it would.

Panton--Drew--the two rough sailors who had been such faithful companions--the rest of the crew? Was he the only survivor?

"Ahoy-y-y-y-y!"

A long-drawn, hollow, echoing hail came from a distance out of the darkness, and it was repeated again and again, before he could command himself and reply. For his throat seemed to be contracted--relief-- joy--grat.i.tude to Heaven, combined to make him, in his weak exhausted state, hysterical, and his answering shout was feeble in the extreme.

But it was heard, and another hail came, which he answered with more vigour, and the knowledge that help was not far away nerved him to fresh efforts. These were encouraged by hail after hail, hoa.r.s.e, hollow, and terrible, as they were repeated, till all at once a voice sent a thrill of delight through him, for he recognised it, and its words,--

"Where are you, sir? This way."

"Here! Who is it?" cried Oliver, hoa.r.s.ely. "Smith?"

"Ay, ay, sir! Both on us. Me and Billy Wriggs. Hah! I got yer.

Three cheers, Billy, and give it throat. Why, we began to think you was nabbed by the n.i.g.g.e.rs or else drown dead."

"Success to yer, sir," came in a hoa.r.s.e voice. "Wait till we gets him out, Tommy, and then we'll cheer, ho!"

"Mr Panton--Mr Drew--the others?" cried Oliver, as he clung to the man who had grasped him by the arms.

"Oh, they're all right, sir."

"Nay, nay, speak the truth, Tommy," growled Wriggs, whose hoa.r.s.e voice sounded awful in the black echoing darkness.

"Don't you be so nation tickler, Billy," cried the other angrily.

"Well, they aren't quite all right, being as you may say regular washed out, but they've all alive 'o!"

"Far as we knows, sir," interposed Wriggs. "But you step forrard, sir, and lets get out o' this here waterworks' pipe."

"Is--is it far to the light?" asked Oliver.

"Not it, sir. Clost here."

"Speak the truth, Tommy, speak the truth," growled Wriggs.

"You won't be happy, Billy, till I gives you one on the nose. Well, sir, it aren't so werry far, an' fore long you'll be able to see the light a shinin' in, where Billy here stood up to his knees a ketchin' on us all as we come down stream, and settin' on us all in a row, on a bit of a shelf to dry a bit, 'fore we went any furder."

"You helped, Tommy."

"Well, yes, soon as I'd let about two barrels o' water run out o' me."

"Speak the truth, Tommy."

"Oh, well, one barrel, then," cried Smith, angrily. "I'll say half a pannikin, if you like. Yes, sir, I helped a bit, and counted us as we was ketched, and then as you didn't come, Billy and me come arter yer and here yer are."

"Which is the truth, Tommy, lad, so stick to that."

They journeyed on till there was a faint dawn of light on ahead, which grew lighter and lighter as they waded forward, till the water, lava and pumice of the arched-over roof became visible. Then there was a hail which was answered, and at last in the twilight the figures of their comrades could be seen seated on the lava edge of the subterranean river, one standing in the middle, evidently gazing anxiously toward the inner portions of the cavern.

In all thankfulness hands were grasped, and then the party waded on, wash, wash with the rapid stream, now not knee deep. The light grew stronger and stronger, till at last there was a bright flash along the smooth water, a sharp bend was turned, and some hundred yards before them there was a low arch laced with ferns, opening out upon blue water and sunshine.

This was approached in silence and with great caution, fresh cartridges were placed in the well-drained guns, though doubts were felt as to their being of any use, if the savages knew of the exit of the waters, and were lying in wait.

But all was still, and as they crept on with Panton and Drew now taking the lead, and all feeling as if light were the great reviver of all, the opening was approached, and they stepped out into the daylight where the little river ran on along its narrow path in the jungle--a path they followed for a time, the growth being too dense on either side for the dry land to be sought.

Then all at once Panton halted, and held up his hand for silence.

There was no need, for they had heard voices from somewhere forward, and in despair they stood gazing out at the sunlit lagoon, feeling that a more desperate fight than ever was before them now when they were utterly exhausted, and their ammunition probably spoiled.

"Ah! Thank Heaven!" cried Oliver, springing forward through the water with all his weakness gone, and now the men cheered frantically. For there in front gliding into sight, and not a hundred yards away, was the lugger with two men visible, and these heard and returned the cheer.

As in Oliver's case every one forgot his weakness and exhaustion, in his efforts to wade out toward the lugger which was steered to meet them through the warm sunny water, and they climbed on board.

"Where's Mr Rimmer?" was Oliver's first question.

"Just close handy somewhere," was the reply. "He landed an hour ago, sir, to try and find some way through the forest, so that we could come across to-night and get to you at the brig."

"Ahoy! Look yonder!" cried Panton, and he waved his hand to a figure on a point about a mile along the lagoon, signalling with his hat at the end of a bamboo.

The helm was put down, and the lugger glided softly over the smooth water between the thickly wooded sh.o.r.e and the surf-beaten reef, to where Mr Rimmer waded out to meet them.
