Between the _Somma_, however, and the cone the space is narrow enough; moreover, several stones fell around us, and made the circuit anything but agreeable. Tischbein now felt more disgusted than ever with Vesuvius, as the monster, not content with being hateful, showed an inclination to become mischievous also.
As, however, the presence of danger generally exercises on man a kind of attraction, and calls forth a spirit of opposition in the human breast to defy it, I bethought myself that, in the interval of the eruptions, it would be possible to climb up the cone to the crater, and to get back before it broke out again. I held a council on this point with our guides under one of the overhanging rocks of the Somma, where, encamped in safety, we refreshed ourselves with the provisions we had brought with us. The younger guide was willing to run the risk with me; we stuffed our hats full of linen and silk handkerchiefs, and, staff in hand, we prepared to start, I holding on to his girdle.
The little stones were yet rattling around us, and the ashes still drizzling, as the stalwart youth hurried forth with me across the hot glowing rubble. We soon stood on the brink of the vast chasm, the smoke of which, although a gentle air was bearing it away from us, unfortunately veiled the interior of the crater, which smoked all round from a thousand crannies. At intervals, however, we caught sight through the smoke of the cracked walls of the rock. The view was neither instructive nor delightful; but for the very reason that one saw nothing, one lingered in the hope of catching a glimpse of something more; and so we forgot our slow counting. We were standing on a narrow ridge of the vast abyss: of a sudden the thunder pealed aloud; we ducked our heads involuntarily, as if that would have rescued us from the precipitated masses. The smaller stones soon rattled, and without considering that we had again an interval of cessation before us, and only too much rejoiced to have outstood the danger, we rushed down and reached the foot of the hill, together with the drizzling ashes, which pretty thickly covered our heads and shoulders.
Tischbein was heartily glad to see me again. After a little scolding and a little refreshment, I was able to give my especial attention to the old and new lava. And here the elder of the guides was able to instruct me accurately in the signs by which the age of the several strata was indicated. The older were already covered with ashes, and rendered quite smooth; the newer, especially those which had cooled slowly, presented a singular appearance. As, sliding along, they carried away with them the solid objects which lay on the surface, it necessarily happened that from time to time several would come into contact with each other, and these again being swept still further by the molten stream, and pushed one over the other, would eventually form a solid mass with wonderful jags and corners, still more strange even than the somewhat similarly formed piles of the icebergs. Among this fused and waste matter I found many great rocks, which, being struck with a hammer, present on the broken face a perfect resemblance to the primeval rock formation. The guides maintained that these were old lava from the lowest depths of the mountain, which are very often thrown up by the volcano.
