I stood on the very summit of the southernmost of Snæfell's peaks. The range of the eye extended over the whole island. By an optical law which obtains at all great heights, the shores seemed raised and the centre depressed. It seemed as if one of Helbesmer's raised maps lay at my feet. I could see deep valleys intersecting each other in every direction, precipices like low walls, lakes reduced to ponds, rivers abbreviated into streams. On my right were numberless glaciers and innumerable peaks, some plumed with feathery clouds of smoke. The undulating surface of these endless mountains, crested with sheets of snow, reminded one of a stormy sea. If I looked westward, there the ocean lay spread out in all its magnificence, like a mere continuation of those flock-like summits. The eye could hardly tell where the snowy ridges ended and the foaming waves began. I was thus steeped in the marvellous ecstasy which all high summits develop in the mind; and now without giddiness, for I was beginning to be accustomed to these sublime aspects of nature. My dazzled eyes were bathed in the bright flood of the solar rays. I was forgetting where and who I was, to live the life of elves and sylphs, the fanciful creation of Scandinavian superstitions. I felt intoxicated with the sublime pleasure of lofty elevations without thinking of the profound abysses into which I was shortly to be plunged. But I was brought back to the realities of things by the arrival of Hans and the Professor, who joined me on the summit. My uncle pointed out to me in the far west a light steam or mist, a semblance of land, which bounded the distant horizon of waters. "Greenland!" said he. "Greenland?" I cried. "Yes; we are only thirty-five leagues from it; and during thaws the white bears, borne by the ice fields from the north, are carried even into Iceland. But never mind that. Here we are at the top of Snæfell and here are two peaks, one north and one south. Hans will tell us the name of that on which we are now standing." The question being put, Hans replied: "Scartaris." My uncle shot a triumphant glance at me. "Now for the crater!" he cried. The crater of Snæfell resembled an inverted cone, the opening of which might be half a league in diameter. Its depth appeared to be about two thousand feet. Imagine the aspect of such a reservoir, brim full and running over with liquid fire amid the rolling thunder. The bottom of the funnel was about 250 feet in circuit, so that the gentle slope allowed its lower brim to be reached without much difficulty. Involuntarily I compared the whole crater to an enormous erected mortar, and the comparison put me in a terrible fright. "What madness," I thought, "to go down into a mortar, perhaps a loaded mortar, to be shot up into the air at a moment's notice!" But I did not try to back out of it. Hans with perfect coolness resumed the lead, and I followed him without a word.
