urce, rolled on without ceasing new
waves of incandescent matter.

The first waves of lava which fell in the lake immediately solidified
and accumulated so as speedily to emerge from it. Upon their surface
fell other waves, which in their turn became stone, but a step
nearer the center of the lake. In this manner was formed a pier which
threatened to gradually fill up the lake, which could not overflow, the
water displaced by the lava being evaporated. The hissing of the water
rent the air with a deafening sound, and the vapor, blown by the wind,
fell in rain upon the sea. The pier became longer and longer, and the
blocks of lava piled themselves one on another. Where formerly stretched
the calm waters of the lake now appeared an enormous mass of smoking
rocks, as if an upheaving of the soil had formed immense shoals. Imagine
the waters of the lake aroused by a hurricane, then suddenly solidified
by an intense frost, and some conception may be formed of the aspect of
the lake three hours after the eruption of this irresistible torrent of
lava.

This time water would be vanquished by fire.

Nevertheless it was a fortunate circumstance for the colonists that the
effusion of lava should have been in the direction of Lake Grant. They
had before them some days' respite. The plateau of Prospect Heights,
Granite House, and the dockyard were for the moment preserved. And these
few days it was necessary to employ in planking and carefully calking
the vessel, and launching her. The colonists would then take refuge on
board the vessel, content to rig her after she should be afloat on the
waters. With the danger of an explosion which threatened to destroy the
island there could be no security on shore. The walls of Granite House,
once so sure a retreat, might at any moment fall in upon them.

During the six following days, from the 25th to the 30th of January, the
colonists accomplished as much of the construction of their vessel as
twenty men could have done. They hardly allowed themselves a moment's
repose, and the glare of the flames which shot from the crater enabled
them to work night and day. The flow of lava continued, but perhaps
less abundantly. This was fortunate, for Lake Grant was almost entirely
choked up, and if more lava should accumulate it would inevitably spread
over the plateau of Prospect Heights, and thence upon the beach.

But if the island was thus partially protected on this side, it was not
so with the
