The Mysterious Island, Jules Verne [freenovel24 txt] 📗

to notice that absolute silence did not reign there.

Having arrived at the bottom of one of those sombre cavities, which extended several hundred feet into the interior of the mountain, he was surprised to hear deep muttering sounds which were intensified by the sonority of the rocks.

Spilett, who was with him, also heard these distant murmurs, which indicated an awakening of the subterranean fires.

Several times they listened, and they came to the conclusion that some chemical reaction was going on in the bowels of the earth.

“The volcano is not entirely extinct,” said the reporter.

“It is possible that, since our exploration of the crater, something has happened in its lower regions. All volcanoes, even those which are said to be extinct, can, evidently, become active again.”

“But if Mount Franklin is preparing for another eruption, is not Lincoln Island in danger?”

“I don’t think so,” answered the engineer. “The crater, that is to say, the safety-valve, exists, and the overflow of vapors and lavas will escape, as heretofore, by its accustomed outlet.”

“Unless the lavas make a new passage towards the fertile parts of the island.”

“Why, my dear Spilett, should they not follow their natural course?”

“Well, volcanoes are capricious.”

“Notice,” said Smith, “that all the slope of the mountain favors the flow of eruptive matter towards the valleys which we are traversing at present. It would take an earthquake to so change the centre of gravity of the mountain as to modify this slope.”

“But an earthquake is always possible under these conditions.”

“True,” replied the engineer, “especially when the subterranean forces are awakening, and the bowels of the earth, after a long repose, chance to be obstructed. You are right, my dear Spilett, an eruption would be a serious thing for us, and it would be better if this volcano has not the desire to wake up; but we can do nothing. Nevertheless, in any case, I do not think Prospect Plateau could be seriously menaced. Between it and the lake there is quite a depression in the land, and even if the lavas took the road to the lake, they would be distributed over the downs and the parts adjoining Shark Gulf.”

“We have not yet seen any smoke from the summit, indicating a near eruption,” said Spilett.

“No,” answered the engineer, “not the least vapor has escaped from the crater. It was but yesterday that I observed its upper part. But it is possible that rocks, cinders, and hardened lavas have accumulated in the lower part of its chimney, and, for the moment, this safety-valve is overloaded. But, at the first serious effort, all obstacles will disappear, and you may be sure, my dear Spilett, that neither the island, which is the boiler, nor the volcano, which is the valve, will burst under the pressure. Nevertheless, I repeat, it is better to wish for no eruption.”

“And yet we are not mistaken,” replied the reporter. “We plainly hear ominous rumblings in the depths of the volcano!”

“No,” replied the engineer, after listening again with the utmost attention, “that is not to be mistaken. Something is going on there the importance of which cannot be estimated nor what the result will be.”

Smith and Spilett, on rejoining their companions, told them of these things.

“All right!” cried Pencroff. “This volcano wants to take care of us! But let it try! It will find its master!”

“Who’s that?” asked the negro.

“Our genius, Neb, our good genius, who will put a gag in the mouth of the crater if it attempts to open it.”

The confidence of the sailor in the guardian of the island was absolute, and, indeed, the occult power which had so far been manifested seemed limitless; but, thus far this being had escaped all the efforts the colonists had made to discover him.

From the 19th to the 25th of February, the investigations were conducted in the western portion of Lincoln Island, where the most secret recesses were searched. They even sounded each rocky wall, as one knocks against the walls of a suspected house. The engineer went so far as to take the exact measure of the mountain, and he pushed his search to the last strata sustaining it. It was explored to the summit of the truncated cone which rose above the first rocky level, and from there to the upper edge of the enormous cap at the bottom of which opened the crater.

They did more; they visited the gulf, still extinct, but in whose depths the rumblings were distinctly heard. Nevertheless, not a smoke, not a vapor, no heat in the wall, indicated a near eruption. But neither there, nor in any other part of Mount Franklin, did the colonists find the traces of him whom they sought.

Their investigations were then directed over all the tract of downs. They carefully examined the high lava walls of Shark Gulf from base to summit, although it was very difficult to reach the water level. No one! Nothing!

These two words summed up in brief the result of all the useless fatigues Smith and his companions had been at, and they were a trifle annoyed at their ill success.

But it was necessary now to think of returning, as these researches could not be pursued indefinitely. The colonists were convinced that this mysterious being did not reside upon the surface of the island, and strange thoughts floated through their overexcited imaginations; Neb and Pencroff, particularly, went beyond the strange into the region of the supernatural. The 25th of February, the colonists returned to Granite House, and by means of the double cord, shot by an arrow to the door-landing, communication was established with their domain.

One month later, they celebrated the third anniversary of their arrival on Lincoln Island.

After three years⁠—The question of a new ship⁠—Its determination⁠—Prosperity of the colony⁠—The shipyard⁠—The cold weather⁠—Pencroff resigned⁠—Washing⁠—Mount Franklin.

Three years had passed since the prisoners had fled from Richmond, and in all that time their conversation and their thoughts had been of the fatherland.

They had no doubt that the war was ended, and that
