THE BURNING MOUNTAIN.

The tunnel through which Ashman propelled the canoe containing himself and Ariel, was more than a hundred yards in length. It was only for the smallest distance that the craft was in darkness, when the water began to reflect light and reveal its outlines.

A few minutes later the tunnel was pa.s.sed, and they debouched into an expansion of the enchanted lake. The second division was similar to the other and almost as large, but its appearance was tenfold more wonderful.

The sheet of water may be said to have been divided into two nearly equal parts by the narrow tunnel running under the ma.s.s of rocks described. One division was in the outer air, after the usual fashion of lakes, while the other was wholly underground.

The interior lake was nearly circular in shape, with an arching roof hundreds of feet high. It was surrounded by towering crags, and volcanic ma.s.ses of stone, which gave it an appearance different from anything on which Fred Ashman had ever looked. Nothing grander, wilder, more picturesque or romantic can be conceived. It was a scene which an explorer could stand for hours and contemplate in rapt admiration.

But the most amazing feature of this underground lake was the way in which it was illuminated, so that every portion stood out in as bold relief as if under the flaming sun of mid-day.

At the western side, the sh.o.r.e, as was the case in nearly all other directions, was a ma.s.s of jagged rocks, piled upon each other in the wildest confusion. Beyond these rocks, was a vast chasm above the level of the lake, and extending right and left for a distance of fifty rods. This huge chasm was one ma.s.s of crimson light, whose rays pierced every nook and cranny on every side of the lake.

The eye gazing in that direction saw something similar to that which greets the traveller in the far north, when viewing the play of the aurora borealis in the horizon, or when the red sun is rising from its ocean bed.

This enormous opening was so surcharged with light that Ashman, after contemplating it but a minute or two, did not need to ask its source.

Beyond the area of illumination was the burning mountain whose blood-red glow covered the entire surface and sh.o.r.es of the underground portion of the enchanted lake. The volcano had been aflame for ages, and was likely to continue to burn for centuries to come.

Such an eternal conflagration must have an outlet for the vast quant.i.ty of vapor generated, and Ashman wondered that he had not noticed the ascending smoke on his way thither. He recalled that when he and his friend were coming up the Xingu, far below the last rapids, they observed a dark cloud resting in the western horizon. There was no thought at that time that it was caused by a burning mountain, but such must have been the fact. The most singular fact was, that while on his way across the lake to the tunnel, he had failed to notice and remark it.

There was a steady draft in the direction of the flaming cavern. He had observed it while paddling through the tunnel where it was strong enough to a.s.sist in the propulsion of the canoe. It was caused by the ascent of the vapor through the chimney of the fiery mountain, and averted the intolerable heat that otherwise would have been felt over every portion of the lake. As it was, a moderate increase of temperature was perceptible.

Ashman was tempted to paddle the canoe to the black rocks which separated the chasm from the lake, and he timidly moved the blade, restrained by the fear of something in the nature of a "back draft,"

which might consume them before they could escape.

Ariel a.s.sured him that she had never encountered or heard of anything of the kind, though she had often visited this remarkable region in the company of her father. Thereupon Ashman sent the boat ahead faster than before, and a minute later the bow touched the rocky wharf.

Stepping out, he drew the bow upon the rocks, so as to hold it fast, and, extending his hand, a.s.sisted her to sh.o.r.e. Then he drew the craft still further up, and, taking her hand again in his own, began picking their way over the jagged bowlders and stones to the edge of the volcano.

From the margin of the lake to the other side of the ma.s.s of rocks was a hundred feet. This may be defined as a solid wall, shutting out the water from the burning mountain. The rocks rose to a height of a dozen rods or so, attaining which a spectator found himself half-way across the dividing ridge, where, viewed from the lake, his figure looked as if stamped in ink on the crimson background.

It was here that the lovers paused and viewed the striking picture spread out before their vision.

That which they saw might properly be considered the crater of the volcano. It was four or five acres in extent, irregular in contour, and so filled with gases and vapors that one could not see the bottom, while the jagged boundary on the farther side came out to view only at intervals, when the obstructing smoke was swept aside.

Spiral columns of black vapor twisted swiftly upward from the fiery depths, sometimes side by side, and sometimes they would unite and climb toward the opening above, like a couple of huge serpents struggling together. The air quivered and pulsated in certain portions, as if with fervid heat, and Ashman fancied once or twice that he caught glimpses of a vast ma.s.s of molten stuff, far down in the mountain, surging; seething and turning upon itself with terrific violence. But the glare was so dazzling that it was like staring at the sun, and he was compelled to withdraw his gaze.

The opening above, through which all this vapor and gas effected its escape into the clear atmosphere outside, was of irregular outline and no more than twenty feet across. It was at a great height above the spectators, and ought to have been visible many miles in every direction.

Now and then Ashman caught the odor of the sulphurous fumes rising from the naming depth, and he could not help reflecting that if the ascending vapors should swerve toward them only for a minute or two, they would be asphyxiated before they could get away; but he could not shrink, when his lovely companion stood so boldly by his side, unmoved by the impressive scene.

When he had become accustomed in a degree to the sight, the like of which he had never viewed before, he recalled that they could not occupy a more conspicuous position, in the event of being pursued by their enemies to the underground lake.

As we have explained, they were standing on the highest portion of the rocky wall, separating the burning mountain from the subterranean portion of the enchanted lake. In this situation, they were in sight from every portion of the sh.o.r.e; any one entering by the tunnel, as they had done, would descry them almost at once, because of the vivid background against which their figures were thrown.

This fact led Ashman to turn to his love and suggest that they should leave the spot. She nodded her head in acquiescence, and, still clasping hands, they began picking their way down among the bowlders to the spot where they had left their canoe a short time before.

CHAPTER x.x.xIII.

THE PURSUERS.

Haffgo, king of the Murhapas, intended to keep his promise to Ziffak, so far as permitting the explorers to remain in his village until the morrow, at which time he intended that the men should be allowed to go in safety.

But the barbarian was very similar to some of us whose resentment grows with reflection. When he recalled the admiring glances of the handsome young member of the company towards his beloved Ariel, his anger became intense, fanned by the strong suspicion that the princess herself felt some interest in the stranger.

At this critical time, Waggaman put in an appearance. The ruffian was shrewd enough to see his opportunity, and it took him but a few minutes to rouse him to the exploding point. He determined that every one of the whites should die, and he ordered the a.s.sault which has already been described.

As has been explained, the king kept within his home, while the attack was under way; but since he resided adjoining the structure which was a.s.saulted, he was aware of every phase of the progress.

His rage has been hinted at because of the repulse of his warriors directly under his own eyes; but when he came to learn that the youth against whom his resentment burned so hotly was not within the building; that the two who had fought so bravely had escaped with their native helpers; that his own daughter the princess was absent; that she had been seen fleeing with the white youth in the direction of the enchanted lake:--when all this became known to the ruler, it may be said that his fury was such that no language could do it justice. It is not impossible that the despot felt thus himself, for, without pausing to give utterance to a few of his imaginings, he made instant preparations to follow the couple to the region which he never permitted a white man to look upon.

A native woman had seen the princess pa.s.s up the side of the river, followed a few minutes later by the young man. Her curiosity led her to watch them. She saw the two meet and stand for some time in loving converse. Then one of the white men stole behind them and was about to fire his dreadful weapon, when Ziffak hurled his terrible javelin which pinned him to the ground. Then the native woman hastened to the palace to tell the news, but she could not gain the chance for some time.

When the king turned upon his brother for an explanation of what he had done, Ziffak was prepared. It was the intention of Burkhardt to shoot not the white man but the princess herself, because she had refused his love. He heard Burkhardt mutter those words to himself and it was because of those words that Ziffak drove his javelin through his body.

King Haffgo looked sharply at his kinsman when he made this unblushing response, but his doubts if there were any quickly vanished, when he recalled the impetuosity with which he had attacked the defenders in the house and the vigor of his pursuit and his evident indignation and chagrin at the escape of the two white men. No, Ziffak might talk plainly with his royal brother, but when the time for action came he was a true Murhapa, who knew only his duty to his king.

Besides, the little flurry between the two had helped to clear away the fogs of misunderstanding as the lightning often purifies the murky atmosphere. The pursuit of the lovers was quickly organized, for they now occupied the thoughts of the king to the exclusion of everything else. Grimcke and Long could not be far off, and a vigorous hunt was likely to discover one or both of them, but the king gave orders that no attempt of the kind should be made. It was his intention to leave the village for an indefinite time, and he wished every one of his warriors to remain while he was absent. It cannot be said that he was afraid of such an insignificant force, but there was a strong vein of superst.i.tion in his nature, which caused a vague fear of the men that had escaped him with such wonderful cleverness. Individuals who could do _that_ sort of thing, were capable of doing things still more marvellous, and to use homely language, King Haffgo was taking no chances.

The party in pursuit numbered just ten persona including the king, Ziffak, Waggaman, and the very pick of the tribe. They were all splendid fellows, fit to be the body-guard of a king, who, when he laid aside the robes of c.u.mbrous dress he was accustomed to wear, and arrayed himself similarly to the warriors, proved himself no mean leader of such a party.

Any one looking upon the little company would have been most impressed by the fact that there were nine dusky barbarians, half naked and as black as Africans, under the guidance of a man as fair as any European; and yet, as the reader knows, the most prominent warrior of the party was the brother of that king, dusky, tall and a giant in stature.

A tribe living in a country as well watered as the Matto Grosso, is sure to be well provided with the means of navigation, though the explorers, when they first reached the neighborhood of the rapids, deemed there was an unusual absence of such craft. A canoe, longer even than that used by our friends in ascending from the Amazon, was carried a short distance down the bank and launched in the Xingu. Five of the warriors seized their long paddles and swung them with the skill of veterans. They were accustomed to that kind of work, and sent the craft up the current with much greater speed than would have been suspected, even by those accustomed to see such work.

Two of the dusky occupants were furnished with bows and arrows, while Waggaman carried his rifle. Thus every species of weapon known to the Murhapas was in the boat.

King Haffgo sat at the stern, his brow dark and threatening, his arms folded and his lips set. His thoughts were too deep for utterance and no one ventured to disturb him. Though the pale countenance was outwardly calm, yet a volcano was raging in that breast, hot and furious enough to burst out and consume the barbarian.

Just in front of him, Ziffak was facing toward the prow, directing the actions of the crew, though for a time little of that was required of him. Waggaman was at the prow, silent, glum, scowling. He did not speak for a long while, but, now and then, glanced at Ziffak. When he did so, he was pretty sure to find the black eyes of the head chieftain fixed upon him.

The two thoroughly distrusted each other. Waggaman knew why that javelin had been driven through the body of his a.s.sociate and, though the convict felt little sorrow for the loss of his companion, yet he hated the chieftain with a deadly hatred, well aware as he was that the feeling was thoroughly reciprocated by Ziffak.

Whether King Haffgo suspected the truth cannot be known, nor is it of importance to know. All the energy of his nature was concentrated in the emotion of fury against Fred Ashman, who had committed the unparalleled presumption of robbing him of his daughter; and even against that lovely maiden he was so incensed that he stood ready to bury his spear in her snowy bosom.

Though it may have seemed strange to Ashman that Ziffak had ordered him to make all haste to the enchanted lake, instead of starting on a direct flight through the woods, returning to the Xingu at a lower point, yet the sagacious chieftain had the best of reasons for his course, as will soon appear.

Had Ashman fled through the forest, the fact would have been discovered at daybreak, if not before, and such a vigorous pursuit would have been pressed as to render escape out of the question. There was a possibility of outwitting Haffgo by the flight to the lake, though it was remote enough to cause the giant warrior to shudder when he reflected upon it.

That which caused Ziffak regret was, that he had not paused long enough before parting from the couple, to arrange a better understanding with them. As it was, he was mostly in the dark concerning their movements, and greatly handicapped by the necessity of appearing to be the devoted ally of his royal brother.

Under the powerful propulsion of the five paddles, the long narrow canoe sped swiftly up the Xingu, and, sooner than even Ziffak antic.i.p.ated, it turned into the narrow stream leading to the enchanted lake. Along this it sped like a swallow until the huge rock with its sentinel came in sight.

It was here that King Haffgo, for the first time, showed some interest in his surroundings. He scanned the ma.s.sive rock closely and manifestly was surprised that the guard did not rise to his feet and challenge them.

Observing that the figure remained motionless, he commanded the craft to approach the rock. This was silently done, the boat halting with the prow touching the ma.s.s of black stone.
