The Mysterious Island, Jules Verne [freenovel24 txt] 📗

reporter, and the lad, after having passed an hour on Prospect Plateau, returned to Granite House. The engineer was pensive, and so much preoccupied that Spilett asked him if he anticipated any near danger.

“Yes and no,” responded Smith.

“But the worst that could happen,” said the reporter, “would be an earthquake, which would overthrow the island. And I don’t think that is to be feared, since the vapors and lava have a free passage of escape.”

“I do not fear an earthquake,” answered Smith, “of the ordinary kind, such as are brought about by the expansion of subterranean vapors. But other causes may bring about great disaster.”

“For example?”

“I do not know exactly⁠—I must see⁠—I must visit the mountain. In a few days I shall have made up my mind.”

Spilett asked no further questions, and soon, notwithstanding the increased violence of the volcano, the inhabitants of Granite House slept soundly.

Three days passed, the 4th 5th, and 6th of January, during which they worked on the ship, and, without explaining himself further, the engineer hastened the work as much as possible. Mount Franklin was covered with a sinister cloud, and with the flames vomited forth incandescent rocks, some of which fell back into the crater. This made Pencroff, who wished to look upon the phenomenon from an amusing side, say:⁠—

“Look! The giant plays at cup and ball! He is a juggler.”

And, indeed, the matters vomited forth fell back into the abyss, and it seemed as if the lavas, swollen by the interior pressure, had not yet risen to the mouth of the crater. At least, the fracture on the northeast, which was partly visible, did not pour forth any torrent on the western side of the mountain.

Meanwhile, however pressing the shipbuilding, other cares required the attention of the colonists in different parts of the island. First of all, they must go to the corral, where the moufflons and goats were enclosed, and renew the provisions for these animals. It was, therefore, agreed that Ayrton should go there the next day, and, as it was customary for but one to do this work, the others were surprised to hear the engineer say to Ayrton:⁠—

“As you are going to the corral tomorrow, I will go with you.”

“Oh! Mr. Smith!” cried the sailor, “our time is very limited, and, if you go off in this way, we lose just that much help!”

“We will return the next day,” answered Smith, “but I must go to the corral⁠—I wish to see about this eruption.”

“Eruption! Eruption!” answered Pencroff, with a dissatisfied air. “What is there important about this eruption? It don’t bother me!”

Notwithstanding the sailor’s protest, the exploration was decided upon for the next day. Herbert wanted to go with Smith, but he did not wish to annoy Pencroff by absenting himself. So, early the next morning, Smith and Ayrton started off with the wagon and onagers.

Over the forest hung huge clouds constantly supplied from Mount Franklin with fuliginous matter. They were evidently composed of heterogeneous substances. It was not altogether the smoke from the volcano that made them so heavy and opaque. Scoriæ in a state of powder, pulverized puzzolan and grey cinder as fine as the finest fecula, were held in suspension in their thick folds. These cinders remain in air, sometimes, for months at a time. After the eruption of 1783, in Iceland, for more than a year the atmosphere was so charged with volcanic powder that the sun’s rays were scarcely visible.

Usually, however, these pulverized matters fall to the earth at once, and it was so in this instance. Smith and Ayrton had hardly reached the corral, when a sort of black cloud, like fine gunpowder, fell, and instantly modified the whole aspect of the ground. Trees, fields, everything was covered with a coating several fingers deep. But, most fortunately, the wind was from the northeast, and the greater part of the cloud was carried off to sea.

“That is very curious,” said Ayrton.

“It is very serious,” answered Smith. This puzzolan, this pulverized pumice stone, all this mineral dust in short, shows how deep-seated is the commotion in the volcano.

“But there is nothing to be done.”

“Nothing, but to observe the progress of the phenomenon. Employ yourself, Ayrton, at the corral, and meanwhile I will go up to the sources of Red Creek and examine the state of the mountain on its western side. Then⁠—”

“Then, sir?”

“Then we will make a visit to Crypt Dakkar⁠—I wish to see⁠—Well, I will come back for you in a couple of hours.”

Ayrton went into the corral, and while waiting for the return of the engineer occupied himself with the moufflons and goats, which showed a certain uneasiness before these first symptoms of an eruption.

Meantime Smith had ventured to climb the eastern spurs of the mountain, and he arrived at the place where his companions had discovered the sulphur spring on their first exploration.

How everything was changed! Instead of a single column of smoke, he counted thirteen escaping from the ground as if thrust upward by a piston. It was evident that the crust of earth was subjected in this place to a frightful pressure. The atmosphere was saturated with gases and aqueous vapors. Smith felt the volcanic tufa, the pulverulent cinders hardened by time, trembling beneath him, but he did not yet see any traces of fresh lava.

It was the same with the western slope of the mountain. Smoke and flames escaped from the crater; a hail of scoriæ fell upon the soil; but no lava flowed from the gullet of the crater, which was another proof that the volcanic matter had not attained the upper orifice of the central chimney.

“And I would be better satisfied if they had!” said Smith to himself. “At least I would be certain that the lavas had taken their accustomed route. Who knows if they may not burst forth from some new mouth? But that is not the danger! Captain Nemo has well foreseen it! No! the danger is not there!”

Smith went forward as far as the
