“Let us get on,” was the engineer’s invariable reply.
And they worked away without losing a moment.
“Master,” asked Neb, a few days later, “do you think all this could have happened if Captain Nemo had been still alive?”
“Certainly, Neb,” answered Cyrus Harding.
“I, for one, don’t believe it!” whispered Pencroft to Neb.
“Nor I!” answered Neb seriously.
During the first week of March appearances again became menacing. Thousands of threads like glass, formed of fluid lava, fell like rain upon the island. The crater was again boiling with lava which overflowed the back of the volcano. The torrent flowed along the surface of the hardened tufa, and destroyed the few meager skeletons of trees which had withstood the first eruption. The stream, flowing this time towards the southwest shore of Lake Grant, stretched beyond Creek Glycerine, and invaded the plateau of Prospect Heights. This last blow to the work of the colonists was terrible. The mill, the buildings of the inner court, the stables, were all destroyed. The affrighted poultry fled in all directions. Top and Jup showed signs of the greatest alarm, as if their instinct warned them of an impending catastrophe. A large number of the animals of the island had perished in the first eruption. Those which survived found no refuge but Tadorn Marsh, save a few to which the plateau of Prospect Heights afforded asylum. But even this last retreat was now closed to them, and the lava-torrent, flowing over the edge of the granite wall, began to pour down upon the beach its cataracts of fire. The sublime horror of this spectacle passed all description. During the night it could only be compared to a Niagara of molten fluid, with its incandescent vapors above and its boiling masses below.
The colonists were driven to their last entrenchment, and although the upper seams of the vessel were not yet calked, they decided to launch her at once.
Pencroft and Ayrton therefore set about the necessary preparations for the launching, which was to take place the morning of the next day, the 9th of March.
But during the night of the 8th an enormous column of vapor escaping from the crater rose with frightful explosions to a height of more than three thousand feet. The wall of Dakkar Grotto had evidently given way under the pressure of gases, and the sea, rushing through the central shaft into the igneous gulf, was at once converted into vapor. But the crater could not afford a sufficient outlet for this vapor. An explosion, which might have been heard at a distance of a hundred miles, shook the air. Fragments of mountains fell into the Pacific, and, in a few minutes, the ocean rolled over the spot where Lincoln island once stood.
