"Come, come along; come higher!"
I followed, and in a few minutes I had climbed to the top, which for a circle of ten yards commanded the whole mass of rock.
I looked down the side we had just climbed. The mountain did not rise more than seven or eight hundred feet above the level of the plain; but on the opposite side it commanded from twice that height the depths of this part of the Atlantic. My eyes ranged far over a large space lit by a violent fulguration. In fact, the mountain was a volcano.
At fifty feet above the peak, in the midst of a rain of stones and scoriæ, a large crater was vomiting forth torrents of lava which fell in a cascade of fire into the bosom of the liquid mass. Thus situated, this volcano lit the lower plain like an immense torch, even to the extreme limits of the horizon. I said that the submarine crater threw up lava, but no flames. Flames require the oxygen of the air to feed upon, and cannot be developed under water; but streams of lava, having in themselves the principles of their incandescence, can attain a white heat, fight vigorously against the liquid element, and turn it to vapor by contact.
Rapid currents bearing all these gases in diffusion, and torrents of lava, slid rapidly to the bottom of the mountain like an eruption of Vesuvius on another Terra del Greco.
There indeed, under my eyes, ruined, destroyed, lay a town—its roofs open to the sky, its temples fallen, its arches dislocated, its columns lying on the ground, from which one could still recognize the massive character of Tuscan architecture. Further on, some remains of a gigantic aqueduct; here the high base of an Acropolis, with the floating outline of a Parthenon; there traces of a quay, as if an ancient port had formerly abutted on the borders of the ocean, and disappeared with its merchant vessels and its war galleys. Further on again, long lines of sunken walls and broad deserted streets—a perfect Pompeii escaped beneath the waters. Such was the sight that Captain Nemo brought before my eyes.
Where was I? Where was I? I must know at any cost. I tried to speak, but Captain Nemo stopped me by a ges-
