But the most wonderful thing which they found there was the famous grotto, so familiar to all from the accounts of tourists, and from the well-known description in Hans Andersen's Improvisatore. After that glowing, poetic, and enthusiastic narrative, no other need be attempted. Here they passed three or four days, and when at length they bade adieu to the artist and his wife, it was with many sincere regrets on both sides, and many earnest wishes that they might meet again.
After which they all went back to Naples.
CHAPTER XVII.
Vesuvius.—Ponies and Sticks.—Sand and Lava.—The rocky Steps.—The rolling, wrathful Smoke-clouds.—The Volcano warns them off.—The lost Boy.—A fearful Search.—A desperate Effort.—The sulphurous Vapors.—Over the sliding Sands.
The sight of Vesuvius from a distance had filled David with an ardent desire to visit it, and all the rest shared this feeling. Vesuvius was before them always. The great cloud of dense, black smoke, which hung over it like a pall, was greater, and denser, and blacker than usual. The crater was disturbed. There were rumbling noises in its wondrous interior; and all around and all beneath the volcano gave signs of an approaching eruption. Sometimes the smoke, as it ascended from the crater, would tower up in the air for thousands of feet, far into the sky, a black pillar, which at the summit spread out on all sides, giving to the spectator the vision of a colossal palm tree—the shape and the sign which is the inevitable forerunner of an approaching eruption. At other times the sulphur-laden clouds would hang low over the crest of the mountain, and roll far down its sides, and envelop it in its dense, black, voluminous folds.
As yet, in spite of these appearances, the ascent might be made in safety, though every day lessened the chances of an ascent by increasing the danger. This they learned from Michael Angelo, their guide, whom they had engaged to make the ascent; so they determined to go without any farther delay. Accordingly, two days after their excursion to Baiae, they set out, going first to Portici, where they hired ponies to take them to the foot of the cone; each one supplied himself with a good stout stick to assist his ascent, and Michael Angelo went with them as general manager of the expedition.
On riding, up they found the road good at first, but soon it became somewhat rough. It left the fertile meadows and vineyards at the base of the mountain, and ran over a wild, rocky country, which looked, as Uncle Moses said, like the "abomination of desolation." No verdure appeared, no houses, no flocks, and herds—all was wild, and savage, and dismal. After passing over these lava fields, the party reached what is called the "Hermitage" —a kind of refreshment station near the foot of the cone. Resting here, for a little way they proceeded on foot. The path was now rugged and difficult, and ascended at so steep an angle that it became rather climbing than walking. After a toilsome walk this path ended at the foot of the cone.
Here the mountain arose grandly before them, with its smoke-cloud overhanging its steep sides, ascending from where they stood to where the view was lost in smoke. At one part there was a surface of loose sand, and at another wild, disordered heaps of crumbled lava blocks. Over these last Michael Angelo led them, for these blocks formed stepping-stones by which to make the ascent. A number of men were here with chairs and straps, who offered them assistance; but they all declined, even Uncle Moses choosing to rely on his unassisted muscle.
Then they began the ascent of the cone. The lava blocks were of all sizes, and lay strewn loosely down the steep side. It was like ascending a long, rough stairway, where all the steps are irregular. It was laborious and tedious. Often they had to stop and rest. Uncle Moses felt it most, and the boys had frequently to stop rather on his account. But when they had traversed about two thirds of the way, they began to grow more excited, and in Bob this excitement was most evident. Thinking that the others would take sufficient care of Uncle Moses, he started off alone, and soon was far up, clambering over the rocks like a young chamois.
Usually there is one side of the crater which is accessible. There is almost always some wind which blows the smoke away, and on the windward side the visitor can stand and breathe freely. On the present occasion, however, there was little or no wind; and the smoke, which was far denser than usual, gathered in thick, black folds, and sometimes rolled down the sides of the cone, and hid the crest from view. Michael Angelo expressed a fear that they would not be able to reach the crest; and as they drew nearer, every step showed that this fear was well founded. At last, when they were within easy distance of it, there came rolling down a cloud of smoke, so dense and so full of sulphurous vapor that they all had to stop and cover their faces with their clothes.
