In about an hour we neared the summit, and got under a vast canopy of sulphurous smoke, which, blown by the furious wind, rolled grim and black over the serrated edge, stretched its impenetrable mass between us and the sky, and then swooped down toward the bay, and dispersed in a vast mist. Most parts of the plain, too, were covered with a low ground-fog. It was a grand sight as we paused and looked back before the last effort. The whole sweep of the bay was visible from Sorrento to Baia, together with the islands, scattered like giant sentinels at the mouth; but all looked strange and fantastic through the sulphurous vapor. The sun was setting in a bath of blood and gold, just behind a straight line of ebony clouds with a sharp rim, like a wall of black marble. The white houses on the slopes of Castel a Mare were already looking ghastly in the twilight. Our temples throbbed with fatigue; but the guide cried "Forward," and we soon came to the most disagreeable part of the business. The smoke was forced by the wind in a kind of cascade some fifty yards down the declivity, and as soon as we got into it an awful sense of suffocation came on. The guide swore, and some of us talked of retreating. But the majority were for persevering; and, panting and coughing, we dashed upward, reached the summit, got into the midst of a fearful torrent of black smoke, like that which is vomited by a steamer's funnel, and staggered giddily about seeking which way to go. At this moment a slight form glanced toward us, said a few words to the guide, and presently we were running to the left along black and dizzy precipices, until suddenly we emerged from the volcanic vapor, and were in full view at the same time of the plain and the sea, and of all the wonders of Vesuvius. The girl whose acquaintance I had made in so strange a manner had come to the assistance of the guide, and told him what direction to take in order soonest to escape from the smoke. I spoke to her; but although she recognized me, I think, she did not, or would not remember our former interview. The idea suggested itself that she was touched in her intellect, so I made no farther allusion to the subject. It was evident the guide knew her, and had confidence in her. He asked her advice about the path which it would be advisable to follow; and obeyed her directions implicitly. "Who is that?" I whispered. "It is Ghita, the Volcano-girl," he replied in English, before repeating the Italian name, which might be translated, the "Daughter of the Volcano." I had no time for further inquiries. We were once more in motion, and had enough to do to keep our footing on the rough lava in the teeth of as furious a blast as ever I remember encountering. It would have been dangerous to stand even near a precipice.
