After the exhaustion of the basalt, the volcano, the power of which grew by the extinction of the lesser craters, supplied an egress to lava, ashes, and scoriae, of which I could see lengthened screes streaming down the sides of the mountain like flowing hair.
Such was the succession of phenomena which produced Iceland, all arising from the action of internal fire; and to suppose that the mass within did not still exist in a state of liquid incandescence was absurd; and nothing could surpass the absurdity of fancying that it was possible to reach the earth's centre.
So I felt a little comforted as we advanced to the assault of Snæfell.
The way was growing more and more arduous, the ascent steeper and steeper; the loose fragments of rock trembled beneath us, and the utmost care was needed to avoid dangerous falls.
Hans went on as quietly as if he were on level ground; sometimes he disappeared altogether behind the huge blocks, then a shrill whistle would direct us on our way to him. Sometimes he would halt, pick up a few bits of stone, build them up into a recognisable form, and thus made landmarks to guide us in our way back. A very wise precaution in itself, but, as things turned out, quite useless.
Three hours' fatiguing march had only brought us to the base of the mountain. There Hans bid us come to a halt, and a hasty breakfast was served out. My uncle swallowed two mouthfuls at a time to get on faster. But, whether he liked it or not, this was a rest as well as a breakfast hour and he had to wait till it pleased our guide to move on, which came to pass in an hour. The three Icelanders, just as taciturn as their comrade the hunter, never spoke, and ate their breakfasts in silence.
We were now beginning to scale the steep sides of Snæfell. Its snowy summit, by an optical illusion not unfrequent in mountains, seemed close to us, and yet how many weary hours it took to reach it! The stones, adhering by no soil or fibrous roots of vegetation, rolled away from under our feet, and rushed down the precipice below with the swiftness of an avalanche.
At some places the flanks of the mountain formed an angle with the horizon of at least 36 degrees; it was impossible to climb them, and these stony cliffs had to be tacked round, not without great difficulty. Then we helped each other with our sticks.
I must admit that my uncle kept as close to me as he could; he never lost sight of me, and in many straits his arm furnished me with a powerful support. He himself seemed to possess an instinct for equilibrium, for he never stumbled. The Icelanders, though burdened with our loads, climbed with the agility of mountaineers.
To judge by the distant appearance of the summit of Snæfell, it would have seemed too steep to ascend on our side. Fortunately, after an hour of fatigue and athletic exercises, in the midst of the vast surface of snow presented by the hollow between the two peaks, a kind of staircase appeared unexpectedly which greatly facilitated our ascent. It was formed by one of those torrents of stones flung up by the eruptions, called 'sting' by the Icelanders. If this torrent had not been arrested in its fall by the formation of the sides of the mountain, it would have gone on to the sea and formed more islands.
