The boat stopped, and the colonists perceived a bright light illuminating the vast cavern, so deeply excavated in the bowels of the island, of which nothing had ever led them to suspect the existence.
At a height of a hundred feet rose the vaulted roof, supported on basalt shafts. Irregular arches, strange mouldings, appeared on the columns erected by nature in thousands from the first epochs of the formation of the globe. The basalt pillars, fitted one into the other, measured from forty to fifty feet in height, and the water, calm in spite of the tumult outside, washing their base. The brilliant focus of light, pointed out by the engineer, touched every point of rock, and flooded the walls with light. By reflection the water reproduced the brilliant sparkles,
so that the boat appeared to be floating between two glittering zones.
They could not be mistaken in the nature of the irradiation thrown from the centre light, whose clear rays broke all the angles, all the projections of the cavern. This light proceeded from an electric source, and its white colour betrayed its origin. It was the sun of this cave, and it filled it entirely.
At a sign from Cyrus Harding the oars again plunged into the water, causing a regular shower of gems, and the boat was urged forward towards the light, which was now not more than half a cable’s length distant.
At this place the breadth of the sheet of water measured nearly 350 feet, and beyond the dazzling centre could be seen an enormous basaltic wall, blocking up any issue on that side. The cavern widened here considerably, the sea forming a little lake. But the roof, the side walls, the end cliff, all the prisms, all the peaks, were flooded with the electric fluid, so that the brilliancy belonged to them, and as if the light issued from them.
In the centre of the lake a long cigar-shaped object floated on the surface of the water, silent, motionless. The brilliancy which issued from it escaped from its sides as from two kilns heated to a white heat. This apparatus, similar in shape to an enormous whale, was about 250 feet long, and rose about ten or twelve above the water.
The boat slowly approached it. Cyrus Harding stood up in the bows. He gazed, a prey to violent excitement. Then, all at once, seizing the reporter’s arm—
“It is he! It can only be he!” he cried, “he!—”
