All went well so far. The Maories, stretched beside the fires, did not appear to observe the two fugitives. But in an instant a double fusillade burst forth from both sides of the ridge.

"Back," exclaimed Glenarvan; "those wretches have the eyes of cats and the guns of riflemen!"

And they turned, and once more climbed the steep slope of the mountain, and then hastened to their friends who had been alarmed at the firing.

Glenarvan's hat was pierced by two b.a.l.l.s, and they concluded that it was out of the question to venture again on the ridge between two lines of marksmen.

"Wait till to-morrow," said Paganel, "and as we cannot elude their vigilance, let me try my hand on them."

The night was cold; but happily Kara-Tete had been furnished with his best night gear, and the party wrapped themselves each in a warm flax mantle, and protected by native superst.i.tion, slept quietly inside the inclosure, on the warm ground, still violating with the violence of the internal ebullition.

CHAPTER XIV A BOLD STRATAGEM

NEXT day, February 17th, the sun's first rays awoke the sleepers of the Maunganamu. The Maories had long since been astir, coming and going at the foot of the mountain, without leaving their line of observation.

Furious clamor broke out when they saw the Europeans leave the sacred place they had profaned.

Each of the party glanced first at the neighboring mountains, and at the deep valleys still drowned in mist, and over Lake Taupo, which the morning breeze ruffled slightly. And then all cl.u.s.tered round Paganel eager to hear his project.

Paganel soon satisfied their curiosity. "My friends," said he, "my plan has one great recommendation; if it does not accomplish all that I antic.i.p.ate, we shall be no worse off than we are at present. But it must, it will succeed."

"And what is it?" asked McNabbs.

"It is this," replied Paganel, "the superst.i.tion of the natives has made this mountain a refuge for us, and we must take advantage of their superst.i.tion to escape. If I can persuade Kai-Koumou that we have expiated our profanation, that the wrath of the Deity has fallen on us: in a word, that we have died a terrible death, do you think he will leave the plateau of Maunganamu to return to his village?"

"Not a doubt of it," said Glenarvan.

"And what is the horrible death you refer to?" asked Lady Helena.

"The death of the sacrilegious, my friends," replied Paganel. "The avenging flames are under our feet. Let us open a way for them!"

"What! make a volcano!" cried John Mangles.

"Yes, an impromptu volcano, whose fury we can regulate. There are plenty of vapors ready to hand, and subterranean fires ready to issue forth. We can have an eruption ready to order."

"An excellent idea, Paganel; well conceived," said the Major.

"You understand," replied the geographer, "we are to pretend to fall victims to the flames of the Maori Pluto, and to disappear spiritually into the tomb of Kara-Tete. And stay there three, four, even five days if necessary--that is to say, till the savages are convinced that we have perished, and abandon their watch."

"But," said Miss Grant, "suppose they wish to be sure of our punishment, and climb up here to see?"

"No, my dear Mary," returned Paganel. "They will not do that. The mountain is tabooed, and if it devoured its sacrilegious intruders, it would only be more inviolably tabooed."

"It is really a very clever plan," said Glenarvan. "There is only one chance against it; that is, if the savages prolong their watch at the foot of Maunganamu, we may run short of provisions. But if we play our game well there is not much fear of that."

"And when shall we try this last chance?" asked Lady Helena.

"To-night," rejoined Paganel, "when the darkness is the deepest."

"Agreed," said McNabbs; "Paganel, you are a genius! and I, who seldom get up an enthusiasm, I answer for the success of your plan. Oh! those villains! They shall have a little miracle that will put off their conversion for another century. I hope the missionaries will forgive us."

The project of Paganel was therefore adopted, and certainly with the superst.i.tious ideas of the Maories there seemed good ground for hope.

But brilliant as the idea might be, the difficulty was in the _modus operandi_. The volcano might devour the bold schemers, who offered it a crater. Could they control and direct the eruption when they had succeeded in letting loose its vapor and flames, and lava streams? The entire cone might be engulfed. It was meddling with phenomena of which nature herself has the absolute monopoly.

Paganel had thought of all this; but he intended to act prudently and without pushing things to extremes. An appearance would be enough to dupe the Maories, and there was no need for the terrible realities of an eruption.

How long that day seemed. Each one of the party inwardly counted the hours. All was made ready for flight. The oudoupa provisions were divided and formed very portable packets. Some mats and firearms completed their light equipment, all of which they took from the tomb of the chief. It is needless to say that their preparations were made within the inclosure, and that they were unseen by the savages.

At six o'clock the steward served up a refreshing meal. Where or when they would eat in the valleys of the Ranges no one could foretell. So that they had to take in supplies for the future. The princ.i.p.al dish was composed of half a dozen rats, caught by Wilson and stewed. Lady Helena and Mary Grant obstinately refused to taste this game, which is highly esteemed by the natives; but the men enjoyed it like the real Maories.

The meat was excellent and savory, and the six devourers were devoured down to the bones.

The evening twilight came on. The sun went down in a stormy-looking bank of clouds. A few flashes of lightning glanced across the horizon and distant thunder pealed through the darkened sky.

Paganel welcomed the storm, which was a valuable aid to his plans, and completed his program. The savages are superst.i.tiously affected by the great phenomena of nature. The New Zealanders think that thunder is the angry voice of Noui-Atoua, and lightning the fierce gleam of his eyes.

Thus their deity was coming personally to chastise the violators of the taboo.

At eight o'clock, the summit of the Maunganamu was lost in portentous darkness. The sky would supply a black background for the blaze which Paganel was about to throw on it. The Maories could no longer see their prisoners; and this was the moment for action. Speed was necessary.

Glenarvan, Paganel, McNabbs, Robert, the steward, and the two sailors, all lent a hand.

The spot for the crater was chosen thirty paces from Kara-Tete's tomb.

It was important to keep the oudoupa intact, for if it disappeared, the taboo of the mountain would be nullified. At the spot mentioned Paganel had noticed an enormous block of stone, round which the vapors played with a certain degree of intensity. This block covered a small natural crater hollowed in the cone, and by its own weight prevented the egress of the subterranean fire. If they could move it from its socket, the vapors and the lava would issue by the disenc.u.mbered opening.

The workers used as levers some posts taken from the interior of the oudoupa, and they plied their tools vigorously against the rocky ma.s.s.

Under their united efforts the stone soon moved. They made a little trench so that it might roll down the inclined plane. As they gradually raised it, the vibrations under foot became more distinct. Dull roarings of flame and the whistling sound of a furnace ran along under the thin crust. The intrepid la-borers, veritable Cyclops handling Earth's fires, worked in silence; soon some fissures and jets of steam warned them that their place was growing dangerous. But a crowning effort moved the ma.s.s which rolled down and disappeared. Immediately the thin crust gave way.

A column of fire rushed to the sky with loud detonations, while streams of boiling water and lava flowed toward the native camp and the lower valleys.

All the cone trembled as if it was about to plunge into a fathomless gulf.

Glenarvan and his companions had barely time to get out of the way; they fled to the enclosure of the oudoupa, not without having been sprinkled with water at 220 degrees. This water at first spread a smell like soup, which soon changed into a strong odor of sulphur.

Then the mud, the lava, the volcanic stones, all spouted forth in a torrent. Streams of fire furrowed the sides of Maunganamu. The neighboring mountains were lit up by the glare; the dark valleys were also filled with dazzling light.

All the savages had risen, howling under the pain inflicted by the burning lava, which was bubbling and foaming in the midst of their camp.

Those whom the liquid fire had not touched fled to the surrounding hills; then turned, and gazed in terror at this fearful phenomenon, this volcano in which the anger of their deity would swallow up the profane intruders on the sacred mountain. Now and then, when the roar of the eruption became less violent, their cry was heard:

"Taboo! taboo! taboo!"

An enormous quant.i.ty of vapors, heated stones and lava was escaping by this crater of Maunganamu. It was not a mere geyser like those that girdle round Mount Hecla, in Iceland, it was itself a Hecla. All this volcanic commotion was confined till then in the envelope of the cone, because the safety valve of Tangariro was enough for its expansion; but when this new issue was afforded, it rushed forth fiercely, and by the laws of equilibrium, the other eruptions in the island must on that night have lost their usual intensity.

An hour after this volcano burst upon the world, broad streams of lava were running down its sides. Legions of rats came out of their holes, and fled from the scene.

All night long, and fanned by the tempest in the upper sky, the crater never ceased to pour forth its torrents with a violence that alarmed Glenarvan. The eruption was breaking away the edges of the opening. The prisoners, hidden behind the inclosure of stakes, watched the fearful progress of the phenomenon.

Morning came. The fury of the volcano had not slackened. Thick yellowish fumes were mixed with the flames; the lava torrents wound their serpentine course in every direction.
