Captain Nemo went towards the peak, which he doubtless meant to be his observatory. It was a painful ascent over the sharp lava and the pumice-stones, in an atmosphere often impregnated with a sulphurous smell from the smoking cracks. For a man unaccustomed to walk on land, the Captain climbed the steep slopes with an agility I never saw equalled and which a hunter would have envied. We were two hours getting to the summit of this peak, which was half porphyry and half basalt. From thence we looked upon a vast sea which, towards the north, distinctly traced its boundary line upon the sky. At our feet lay fields of dazzling whiteness. Over our heads a pale azure, free from fog. To the north the disc of the sun seemed like a ball of fire, already horned by the cutting of the horizon. From the bosom of the water rose sheaves of liquid jets by hundreds. In the distance lay the Nautilus like a cetacean asleep on the water. Behind us, to the south and east, an immense country and a chaotic heap of rocks and ice, the limits of which were not visible. On arriving at the summit Captain Nemo carefully took the mean height of the barometer, for he would have to consider that in taking his observations.
