The Mysterious Island, Jules Verne [freenovel24 txt] 📗

By seven o’clock the colonists were no longer able to keep their position on the edge of Jacamar Wood. Not only did the projectiles begin to fall about them, but the lavas, overflowing the bed of Red Creek, threatened to cut off the road from the corral. The first ranks of trees took fire, and their sap, vaporized, made them explode like firecrackers; while others, less humid, remained intact in the midst of the inundation.

The colonists started back. The torrent, owing to the slope of the land, gained eastward rapidly, and as the lower layers of lava hardened, others, boiling, covered them.

Meantime the principal current in the Red Creek Valley became more and more threatening. All that part of the forest was surrounded, and enormous clouds of smoke rolled above the trees, whose roots were already in the lava.

The colonists stopped at the lake shore, half a mile from the mouth of Red Creek. A question of life or death was about to be decided for them. Smith, accustomed to think and reason in the presence of danger, and aware that he was speaking to men who could face the truth, whatever it might be, said to them:⁠—

“Either the lake will arrest this current, and a part of the island will be preserved from complete devastation, or the current will invade the Forests of the Far West, and not a tree, not a plant will be left upon the face of the ground. We will have, upon these rocks stripped of life, the prospect of a death which the explosion of the island may anticipate!”

“Then,” cried Pencroff, crossing his arms and stamping his foot on the ground, “it is useless to work on the ship! Isn’t that so?”

“Pencroff,” answered Smith, “it is necessary to do one’s duty to the end.”

At this moment, the flood of lava, after having eaten its way through the splendid trees of the forest, neared the lake. There was a certain depression in the ground, which, if it had been larger, might, perhaps, suffice to hold the torrent.

“Let us try!” cried Smith.

The idea of the engineer was instantly understood by all. It was necessary to dam, so to speak, this torrent and force it into the lake.

The colonists ran to the shipyard and brought back from there shovels, picks, and hatchets, and by means of earthworks and hewn trees they succeeded, in a few hours, in raising a barrier three feet high and some hundreds of feet long. It seemed to them, when they had finished, that they had not worked more than a few minutes!

It was time. The liquified matter already reached the extremity of the barrier. The flood spread like a swollen river seeking to overflow its banks and threatening to break down the only obstacle which could prevent its devastating all the Far West. But the barrier was sufficient to withstand it, and, after one terrible moment of hesitation, it precipitated itself into Lake Grant by a fall twenty feet high.

The colonists, breathless, without a word, without a gesture, looked upon this struggle of the elements.

What a sight was this, the combat between fire and water! What pen can describe this scene of marvellous horror; what pencil can portray it? The water hissed and steamed at the contact of the boiling lavas. The steam was thrown, whirling, to an immeasurable height in the air, as if the valves of an immense boiler had been suddenly opened. But, great as was the mass of water contained in the lake, it must, finally, be absorbed, since it was not renewed, while the torrent, fed from an inexhaustible source, was ceaselessly pouring in fresh floods of incandescent matter.

The first lavas which fell into the lake solidified at once, and accumulated in such a manner as soon to emerge above the surface. Over these slid other lavas, which in their turn became stone, forming a breakwater, which threatened to fill up the lake, which could not overflow, as its surplus water was carried off in steam. Hissings and shrivellings filled the air with a stunning noise, and the steam, carried off by the wind, fell to the ground in rain. The jetty spread, and where formerly had been peaceable waters appeared an enormous heap of smoking rocks, as if some upheaval of the ground had raised these thousands of reefs. If one can imagine these waters tossed about by a storm, and then suddenly solidified by cold, he will have the appearance of the lake three hours after the irresistible torrent had poured into it.

This time the water had been overcome by the fire.

Nevertheless, it was a fortunate thing for the colonists that the lavas had been turned into the lake. It gave them some days’ respite. Prospect Plateau, Granite House, and the shipyard were safe for the moment. In these few days they must plank and caulk the vessel, launch it, and take refuge upon it, rigging it after it was on the sea. With the fear of the explosion menacing the destruction of the island, it was no longer safe to remain on land. Granite House, so safe a retreat up to this time, might, at any moment, fall!

During the next six days, the colonists worked on the ship with all their might. Sleeping but little, the light of the flames from the volcano permitted them to work by night as well as by day. The eruption continued without cessation, but, perhaps, less abundantly. A fortunate circumstance, since Lake Grant was nearly full; and if fresh lavas had slid over the surface of the former layers, they would inevitably have spread over Prospect Plateau and from there to the shore.

But while this part of the island was partially protected it was otherwise with the west coast.

The second current of lava, following the valley of Fall River, met with no obstacle. The ground on either side of the bank was low, and the incandescent liquid was spread through the forest of
