Their labours were now carried on with feverish ardour. By the 23rd of January the vessel was half-decked over. Up to this time no change had taken place in the summit of the volcano. Vapour and smoke mingled with flames and incandescent stones were thrown up from the crater. But during the night of the 23rd, in consequence of the lava attaining the level of the first stratum of the volcano, the hat-shaped cone which formed over the latter disappeared. A frightful sound was heard. The colonists at first thought the island was rent asunder, and rushed out of Granite House.
This occurred about two o’clock in the morning.
The sky appeared on fire. The superior cone, a mass of rock a thousand feet in height, and weighing thousands of millions of pounds, had been thrown down upon the island, making it tremble to its foundation. Fortunately, this cone inclined to the north, and had fallen upon the plain of sand and tufa stretching between the volcano and the sea. The aperture of the crater being thus enlarged projected towards the sky a glare so intense that by the simple effect of reflection the atmosphere appeared red-hot. At the same time a torrent of lava, bursting from the new summit, poured out in long cascades, like water escaping from a vase too full, and a thousand tongues of fire crept over the sides of the volcano.
“The corral! the corral!” exclaimed Ayrton.
It was, in fact, towards the corral that the lava was rushing, as the new crater faced the east, and consequently the fertile portions of the island, the springs of Red Creek and Jacamar Wood, were menaced with instant destruction.
At Ayrton’s cry the colonists rushed to the onagas’ stables. The cart was at once harnessed. All were possessed by the same thought—to hasten to the corral and set at liberty the animals it enclosed.
Before three in the morning they arrived at the corral. The cries of the terrified musmons and goats indicated the alarm which possessed them. Already a torrent of burning matter and liquefied minerals fell from the side of the mountain upon the meadows as far as the side of the palisade. The gate was burst open by Ayrton, and the animals, bewildered with terror, fled in all directions.
An hour afterwards the boiling lava filled the corral, converting into vapour the water of the little rivulet which ran through it, burning up the house like dry grass, and leaving not even a post of the palisade to mark the spot where the corral once stood.
To contend against this disaster would have been folly—nay, madness. In presence of Nature’s grand convulsions man is powerless.
It was now daylight—the 24th of January. Cyrus Harding and his companions, before returning to Granite House, desired to ascertain the probable direction this inundation of lava was about to take. The soil sloped gradually from Mount Franklin to the east coast, and it was to be feared that, in spite of the thick Jacamar Wood, the torrent would reach the plateau of Prospect Heights.
