"But is it Jan Mayen?" I asked. "Nor that either," he answered. "This is no northern mountain; here are no granite peaks capped with snow. Look, Axel, look!" Above our heads, at a height of five hundred feet or more, we saw the crater of a volcano, through which, at intervals of fifteen minutes or so, there issued with loud explosions lofty columns of fire, mingled with pumice stones, ashes, and flowing lava. I could feel the heaving of the mountain, which seemed to breathe like a huge whale, and puff out fire and wind from its vast blowholes. Beneath, down a pretty steep declivity, ran streams of lava for eight or nine hundred feet, giving the mountain a height of about 1,300 or 1,400 feet. But the base of the mountain was hidden in a perfect bower of rich verdure, amongst which I was able to distinguish the olive, the fig, and vines, covered with their luscious purple bunches. I was forced to confess that there was nothing arctic here. When the eye passed beyond these green surroundings it rested on a wide, blue expanse of sea or lake, which appeared to enclose this enchanting island, within a compass of only a few leagues. Eastward lay a pretty little white seaport town or village, with a few houses scattered around it, and in the harbour of which a few vessels of peculiar rig were gently swayed by the softly swelling waves. Beyond it, groups of islets rose from the smooth, blue waters, but in such numbers that they seemed to dot the sea like a shoal. To the west distant coasts lined the dim horizon, on some rose blue mountains of smooth, undulating forms; on a more distant coast arose a prodigious cone crowned on its summit with a snowy plume of white cloud. To the northward lay spread a vast sheet of water, sparkling and dancing under the hot, bright rays, the uniformity broken here and there by the topmast of a gallant ship appearing above the horizon, or a swelling sail moving slowly before the wind. This unforeseen spectacle was most charming to eyes long used to underground darkness. "Where are we? Where are we?" I asked faintly. Hans closed his eyes with lazy indifference. What did it matter to him? My uncle looked round with dumb surprise. "Well, whatever mountain this may be," he said at last, "it is very hot here. The explosions are going on still, and I don't think it would look well to have come out by an eruption, and then to get our heads broken by bits of falling rock. Let us get down. Then we shall know better what we are about. Besides, I am starving, and parching with thirst." Decidedly the Professor was not given to contemplation. For my part, I could for another hour or two have forgotten my hunger and my fatigue to enjoy the lovely scene before me; but I had to follow my companions.
