An examination of the wreckage showed that their greatest danger, now, lay in fire, for the flames were licking hungrily at the splintered wood of the wrecked cabin, and had already found a foothold upon the lower deck through a great jagged hole which the explosion had opened.

By a miracle no member of the ship's company had been injured by the blast, the origin of which remained for ever a total mystery to all but one-the sailor who knew that Paulvitch had been aboard the Kincaid and in his cabin the previous night. He guessed the truth; but discretion sealed his lips. It would, doubtless, fare none too well for the man who had permitted the arch enemy of them all aboard the ship in the watches of the night, where later he might set an infernal machine to blow them all to kingdom come. No, the man decided that he would keep this knowledge to himself.

As the flames gained headway it became apparent to Tarzan that whatever had caused the explosion had scattered some highly inflammable substance upon the surrounding woodwork, for the water which they poured in from the pump seemed rather to spread than to extinguish the blaze.

Fifteen minutes after the explosion great, black clouds of smoke were rising from the hold of the doomed vessel. The flames had reached the engine-room, and the ship no longer moved toward the sh.o.r.e. Her fate was as certain as though the waters had already closed above her charred and smoking remains.

"It is useless to remain aboard her longer," remarked the ape-man to the mate. "There is no telling but there may be other explosions, and as we cannot hope to save her, the safest thing which we can do is to take to the boats without further loss of time and make land."

Nor was there other alternative. Only the sailors could bring away any belongings, for the fire, which had not yet reached the forecastle, had consumed all in the vicinity of the cabin which the explosion had not destroyed.

Two boats were lowered, and as there was no sea the landing was made with infinite ease. Eager and anxious, the beasts of Tarzan sniffed the familiar air of their native island as the small boats drew in toward the beach, and scarce had their keels grated upon the sand than Sheeta and the apes of Akut were over the bows and racing swiftly toward the jungle. A half-sad smile curved the lips of the ape-man as he watched them go.

"Good-bye, my friends," he murmured. "You have been good and faithful allies, and I shall miss you."

"They will return, will they not, dear?" asked Jane Clayton, at his side.

"They may and they may not," replied the ape-man. "They have been ill at ease since they were forced to accept so many human beings into their confidence. Mugambi and I alone affected them less, for he and I are, at best, but half human. You, however, and the members of the crew are far too civilized for my beasts-it is you whom they are fleeing. Doubtless they feel that they cannot trust themselves in the close vicinity of so much perfectly good food without the danger that they may help themselves to a mouthful some time by mistake."

Jane laughed. "I think they are just trying to escape you," she retorted. "You are always making them stop something which they see no reason why they should not do. Like little children they are doubtless delighted at this opportunity to flee from the zone of parental discipline. If they come back, though, I hope they won't come by night."

"Or come hungry, eh?" laughed Tarzan.

For two hours after landing the little party stood watching the burning ship which they had abandoned. Then there came faintly to them from across the water the sound of a second explosion. The Kincaid settled rapidly almost immediately thereafter, and sank within a few minutes.

The cause of the second explosion was less a mystery than that of the first, the mate attributing it to the bursting of the boilers when the flames had finally reached them; but what had caused the first explosion was a subject of considerable speculation among the stranded company.

Chapter 20

Jungle Island Again

The first consideration of the party was to locate fresh water and make camp, for all knew that their term of existence upon Jungle Island might be drawn out to months, or even years.

Tarzan knew the nearest water, and to this he immediately led the party. Here the men fell to work to construct shelters and rude furniture while Tarzan went into the jungle after meat, leaving the faithful Mugambi and the Mosula woman to guard Jane, whose safety he would never trust to any member of the Kincaid's cut-throat crew.

Lady Greystoke suffered far greater anguish than any other of the castaways, for the blow to her hopes and her already cruelly lacerated mother-heart lay not in her own privations but in the knowledge that she might now never be able to learn the fate of her first-born or do aught to discover his whereabouts, or ameliorate his condition-a condition which imagination naturally pictured in the most frightful forms.

For two weeks the party divided the time amongst the various duties which had been allotted to each. A daylight watch was maintained from sunrise to sunset upon a bluff near the camp-a jutting shoulder of rock which overlooked the sea. Here, ready for instant lighting, was gathered a huge pile of dry branches, while from a lofty pole which they had set in the ground there floated an improvised distress signal fashioned from a red undershirt which belonged to the mate of the Kincaid.

But never a speck upon the horizon that might be sail or smoke rewarded the tired eyes that in their endless, hopeless vigil strained daily out across the vast expanse of ocean.

It was Tarzan who suggested, finally, that they attempt to construct a vessel that would bear them back to the mainland. He alone could show them how to fashion rude tools, and when the idea had taken root in the minds of the men they were eager to commence their labours.

But as time went on and the Herculean nature of their task became more and more apparent they fell to grumbling, and to quarrelling among themselves, so that to the other dangers were now added dissension and suspicion.

More than before did Tarzan now fear to leave Jane among the half brutes of the Kincaid's crew; but hunting he must do, for none other could so surely go forth and return with meat as he. Sometimes Mugambi spelled him at the hunting; but the black's spear and arrows were never so sure of results as the rope and knife of the ape-man.

Finally the men shirked their work, going off into the jungle by twos to explore and to hunt. All this time the camp had had no sight of Sheeta, or Akut and the other great apes, though Tarzan had sometimes met them in the jungle as he hunted.

And as matters tended from bad to worse in the camp of the castaways upon the east coast of Jungle Island, another camp came into being upon the north coast.

Here, in a little cove, lay a small schooner, the Cowrie, whose decks had but a few days since run red with the blood of her officers and the loyal members of her crew, for the Cowrie had fallen upon bad days when it had shipped such men as Gust and Momulla the Maori and that arch-fiend Kai Shang of Fachan.

There were others, too, ten of them all told, the sc.u.m of the South Sea ports; but Gust and Momulla and Kai Shang were the brains and cunning of the company. It was they who had instigated the mutiny that they might seize and divide the catch of pearls which const.i.tuted the wealth of the Cowrie's cargo.

It was Kai Shang who had murdered the captain as he lay asleep in his berth, and it had been Momulla the Maori who had led the attack upon the officer of the watch.

Gust, after his own peculiar habit, had found means to delegate to the others the actual taking of life. Not that Gust entertained any scruples on the subject, other than those which induced in him a rare regard for his own personal safety. There is always a certain element of risk to the a.s.sa.s.sin, for victims of deadly a.s.sault are seldom p.r.o.ne to die quietly and considerately. There is always a certain element of risk to go so far as to dispute the issue with the murderer. It was this chance of dispute which Gust preferred to forgo.

But now that the work was done the Swede aspired to the position of highest command among the mutineers. He had even gone so far as to appropriate and wear certain articles belonging to the murdered captain of the Cowrie-articles of apparel which bore upon them the badges and insignia of authority.

Kai Shang was peeved. He had no love for authority, and certainly not the slightest intention of submitting to the domination of an ordinary Swede sailor.

The seeds of discontent were, therefore, already planted in the camp of the mutineers of the Cowrie at the north edge of Jungle Island. But Kai Shang realized that he must act with circ.u.mspection, for Gust alone of the motley horde possessed sufficient knowledge of navigation to get them out of the South Atlantic and around the cape into more congenial waters where they might find a market for their ill-gotten wealth, and no questions asked.

The day before they sighted Jungle Island and discovered the little land-locked harbour upon the bosom of which the Cowrie now rode quietly at anchor, the watch had discovered the smoke and funnels of a warship upon the southern horizon.

The chance of being spoken to and investigated by a man-of-war appealed not at all to any of them, so they put into hiding for a few days until the danger should have pa.s.sed.

And now Gust did not wish to venture out to sea again. There was no telling, he insisted, but that the ship they had seen was actually searching for them. Kai Shang pointed out that such could not be the case since it was impossible for any human being other than themselves to have knowledge of what had transpired aboard the Cowrie.

But Gust was not to be persuaded. In his wicked heart he nursed a scheme whereby he might increase his share of the booty by something like one hundred per cent. He alone could sail the Cowrie, therefore the others could not leave Jungle Island without him; but what was there to prevent Gust, with just sufficient men to man the schooner, slipping away from Kai Shang, Momulla the Maori, and some half of the crew when opportunity presented?

It was for this opportunity that Gust waited. Some day there would come a moment when Kai Shang, Momulla, and three or four of the others would be absent from camp, exploring or hunting. The Swede racked his brain for some plan whereby he might successfully lure from the sight of the anch.o.r.ed ship those whom he had determined to abandon.

To this end he organized hunting party after hunting party, but always the devil of perversity seemed to enter the soul of Kai Shang, so that wily celestial would never hunt except in the company of Gust himself.

One day Kai Shang spoke secretly with Momulla the Maori, pouring into the brown ear of his companion the suspicions which he harboured concerning the Swede. Momulla was for going immediately and running a long knife through the heart of the traitor.

It is true that Kai Shang had no other evidence than the natural cunning of his own knavish soul-but he imagined in the intentions of Gust what he himself would have been glad to accomplish had the means lain at hand.

But he dared not let Momulla slay the Swede, upon whom they depended to guide them to their destination. They decided, however, that it would do no harm to attempt to frighten Gust into acceding to their demands, and with this purpose in mind the Maori sought out the self-const.i.tuted commander of the party.

When he broached the subject of immediate departure Gust again raised his former objection-that the warship might very probably be patrolling the sea directly in their southern path, waiting for them to make the attempt to reach other waters.

Momulla scoffed at the fears of his fellow, pointing out that as no one aboard any warship knew of their mutiny there could be no reason why they should be suspected.

"Ah!" exclaimed Gust, "there is where you are wrong. There is where you are lucky that you have an educated man like me to tell you what to do. You are an ignorant savage, Momulla, and so you know nothing of wireless."

The Maori leaped to his feet and laid his hand upon the hilt of his knife.

"I am no savage," he shouted.

"I was only joking," the Swede hastened to explain. "We are old friends, Momulla; we cannot afford to quarrel, at least not while old Kai Shang is plotting to steal all the pearls from us. If he could find a man to navigate the Cowrie he would leave us in a minute. All his talk about getting away from here is just because he has some scheme in his head to get rid of us."
