The Mysterious Island by Jules Verne (novels for beginners .txt) 📗

cone of Mount Franklin had fallen, but the lava arrested their progress. It had followed, on one side, the valley of Red Creek, and on the other that of Falls River, evaporating those watercourses in its passage. There was no possibility of crossing the torrent of lava; on the contrary, the colonists were obliged to retreat before it. The volcano, without its crown, was no longer recognizable, terminated as it was by a sort of flat table which replaced the ancient crater. From two openings in its southern and eastern sides an unceasing flow of lava poured forth, thus forming two distinct streams. Above the new crater a cloud of smoke and ashes, mingled with those of the atmosphere, massed over the island. Loud peals of thunder broke, and could scarcely be distinguished from the rumblings of the mountain, whose mouth vomited forth ignited rocks, which, hurled to more than a thousand feet, burst in the air like shells. Flashes of lightning rivaled in intensity the volcano’s eruption.

Towards seven in the morning the position was no longer tenable by the colonists, who accordingly took shelter in the borders of Jacamar Wood. Not only did the projectiles begin to rain around them, but the lava, overflowing the bed of Red Creek, threatened to cut off the road to the corral. The nearest rows of trees caught fire, and their sap, suddenly transformed into vapor, caused them to explode with loud reports, while others, less moist, remained unhurt in the midst of the inundation.

The colonists had again taken the road to the corral. They proceeded but slowly, frequently looking back; but, in consequence of the inclination of the soil, the lava gained rapidly in the east, and as its lower waves became solidified others, at boiling heat, covered them immediately.

Meanwhile, the principal stream of Red Creek Valley became more and more menacing. All this portion of the forest was on fire, and enormous wreaths of smoke rolled over the trees, whose trunks were already consumed by the lava.

The colonists halted near the lake, about half a mile from the mouth of Red Creek. A question of life or death was now to be decided.

Cyrus Harding, accustomed to the consideration of important crises, and aware that he was addressing men capable of hearing the truth, whatever it might be, then said,—

“Either the lake will arrest the progress of the lava, and a part of the island will be preserved from utter destruction, or the stream will overrun the forests of the Far West, and not a tree or plant will remain on the surface of the soil. We shall have no prospect but that of starvation upon these barren rocks—a death which will probably be anticipated by the explosion of the island.”

“In that case,” replied Pencroft, folding his arms and stamping his foot, “what’s the use of working any longer on the vessel?”

“Pencroft,” answered Cyrus Harding, “we must do our duty to the last!”

At this instant the river of lava, after having broken a passage through the noble trees it devoured in its course, reached the borders of the lake. At this point there was an elevation of the soil which, had it been greater, might have sufficed to arrest the torrent.

“To work!” cried Cyrus Harding.

The engineer’s thought was at once understood. It might be possible to dam, as it were, the torrent, and thus compel it to pour itself into the lake.

The colonists hastened to the dockyard. They returned with shovels, picks, axes, and by means of banking the earth with the aid of fallen trees they succeeded in a few hours in raising an embankment three feet high and some hundreds of paces in length. It seemed to them, when they had finished, as if they had scarcely been working more than a few minutes.

It was not a moment too soon. The liquefied substances soon after reached the bottom of the barrier. The stream of lava swelled like a river about to overflow its banks, and threatened to demolish the sole obstacle which could prevent it from overrunning the whole Far West. But the dam held firm, and after a moment of terrible suspense the torrent precipitated itself into Grant Lake from a height of twenty feet.

The colonists, without moving or uttering a word, breathlessly regarded this strife of the two elements.

What a spectacle was this conflict between water and fire! What pen could describe the marvelous horror of this scene—what pencil could depict it? The water hissed as it evaporated by contact with the boiling lava. The vapor whirled in the air to an immeasurable height, as if the valves of an immense boiler had been suddenly opened. But, however considerable might be the volume of water contained in the lake, it must eventually be absorbed, because it was not replenished, while the stream of lava, fed from an inexhaustible source, rolled on without ceasing new waves of incandescent matter.

The first waves of lava which fell in the lake immediately solidified and accumulated so as speedily to emerge from it. Upon their surface fell other waves, which in their turn became stone, but a step nearer the center of the lake. In this manner was formed a pier which threatened to gradually fill up the lake, which could not overflow, the water displaced by the lava being evaporated. The hissing of the water rent the air with a deafening sound, and the vapor, blown by the wind, fell in rain upon the sea. The pier became longer and longer, and the blocks of lava piled themselves one on another. Where formerly stretched the calm waters of the lake now appeared an enormous mass of smoking rocks, as if an upheaving of the soil had formed immense shoals. Imagine the waters of the lake aroused by a hurricane, then suddenly solidified by an intense frost, and some conception may be formed of the aspect of the lake three hours after the eruption of this irresistible torrent of lava.

This time water would be vanquished by fire.

Nevertheless it was a fortunate circumstance for the colonists that the effusion of lava should have been in the direction of Lake Grant. They had before them some days’ respite. The plateau of Prospect Heights, Granite House, and the dockyard were for the moment preserved. And these few days it was necessary to employ in planking and carefully calking the vessel, and launching her. The colonists would then take refuge on board the vessel, content to rig her after she should be afloat on the waters. With the danger of an explosion which threatened to destroy the island there could be no security on shore. The walls of Granite House, once so sure a retreat, might at any moment fall in upon them.

During the six following days, from the 25th to the 30th of January, the colonists accomplished as much of the construction of their vessel as twenty men could have done. They hardly allowed themselves a moment’s repose, and the glare of the flames which shot from the crater enabled them to work night and day. The flow of lava continued, but perhaps less abundantly. This was fortunate, for Lake Grant was almost entirely choked up, and if more lava should accumulate it would inevitably spread over the plateau of Prospect Heights, and thence upon the beach.

But if the island was thus partially protected on this side, it was not so with the western part.

In fact, the second stream of lava, which had followed the valley of Falls River, a valley of great extent, the
