“True,” replied Cyrus Harding, “and I do not fear an earthquake in the sense in which the term is commonly applied to convulsions of the soil provoked by the expansion of subterranean gases. But other causes may produce great disasters.”
“How so, my dear Cyrus?”
“I am not certain. I must consider. I must visit the mountain. In a few days I shall learn more on this point.”
Gideon Spilett said no more, and soon, in spite of the explosions of the volcano, whose intensity increased, and which were repeated by the echoes of the island, the inhabitants of Granite House were sleeping soundly.
Three days passed by—the 4th, 5th, and 6th of January. The construction of the vessel was diligently continued, and without offering further explanations the engineer pushed forward the work with all his energy. Mount Franklin was now hooded by a sombre cloud of sinister aspect, and, amid the flames, vomited forth incandescent rocks, some of which fell back into the crater itself. This caused Pencroft, who would only look at the matter in the light of a joke, to exclaim—
“Ah! the giant is playing at cup and ball; he is a conjuror.”
In fact, the substances thrown up fell back again into the abyss, and it did not seem that the lava, though swollen by the internal pressure, had yet risen to the orifice of the crater. At any rate, the opening on the north-east, which was partly visible, poured out no torrent upon the northern slope of the mountain.
Nevertheless, however pressing was the construction of the vessel, other duties demanded the presence of the colonists on various portions of the island. Before everything it was necessary to go to the corral, where the flocks of musmons and goats were enclosed, and replenish the provision of forage for those animals. It was accordingly arranged that Ayrton should proceed thither the next day, the 7th of January; and as he was sufficient for the task, to which he was accustomed, Pencroft and the rest were somewhat surprised on hearing the engineer say to Ayrton—
“As you are going to-morrow to the corral I will accompany you.”
“But, Captain Harding,” exclaimed the sailor, “our working days will not be many, and if you go also we shall be two pair of hands short!”
