"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.
In order to facilitate the descent, Hans wound his way down the cone by a spiral path. Our route lay amidst eruptive rocks, some of which, shaken out of their loosened beds, rushed bounding down the abyss, and in their fall awoke echoes remarkable for their loud and well-defined sharpness.
In certain parts of the cone there were glaciers. Here Hans advanced only with extreme precaution, sounding his way with his iron-pointed pole, to discover any crevasses in it. At particularly dubious passages we were obliged to connect ourselves with each other by a long cord, in order that any man who missed his footing might be held up by his companions. This solid formation was prudent, but did not remove all danger.
Yet, notwithstanding the difficulties of the descent, down steeps unknown to the guide, the journey was accomplished without accidents, except the loss of a coil of rope, which escaped from the hands of an Icelander, and took the shortest way to the bottom of the abyss.
At mid-day we arrived. I raised my head and saw straight above me the upper aperture of the cone, framing a bit of sky of very small circumference, but almost perfectly round. Just upon the edge appeared the snowy peak of Saris, standing out sharp and clear against endless space.
At the bottom of the crater were three chimneys, through which, in its eruptions, Snæfell had driven forth fire and lava from its central furnace. Each of these chimneys was a hundred feet in diameter. They gaped before us right in our path. I had not the courage to look down either of them. But Professor Liedenbrock had hastily surveyed all three; he was panting, running from one to the other, gesticulating, and uttering incoherent expressions. Hans and his comrades, seated upon loose lava rocks, looked at him with as much wonder as they knew how to express, and perhaps taking him for an escaped lunatic.
Suddenly my uncle uttered a cry. I thought his foot must have slipped and that he had fallen down one of the holes. But, no; I saw him, with arms outstretched and legs straddling wide apart, erect before a granite rock that stood in the centre of the crater, just like a pedestal made ready to receive a statue of Pluto. He stood like a man stupefied, but the stupefaction soon gave way to delirious rapture.
"Axel, Axel," he cried. "Come, come!"
I ran. Hans and the Icelanders never stirred.
