Overjoyed at the idea of finding a human being in a spot which he had at first deemed totally uninhabited, and filled with the hope that the stranger might be able to give him some information relative to the geographical position of the isle, and even perhaps aid him in forming a raft by which they might together escape from the oasis of the Mediterranean, Wagner proceeded toward the mountains. By degrees the wondrous beauty of the scene became wilder, more imposing, but less bewitching, and when he reached the acclivities of the hill, the groves of fruits and copses of myrtles and citrons, of vines and almond shrubs, were succeeded by woods of mighty trees. Further on still the forests ceased and Fernand entered on a wild region of almost universal desolation, yet forming one of the sublimest spectacles that nature can afford. The sounds of torrents, as yet concealed from his view, and resembling the murmur of ocean's waves, inspired feelings of awe; and it was now for the first time since he entered on the region of desolation, having left the clime of loveliness nearly a mile behind, that his attention was drawn to the nature of the soil, which was hard and bituminous in appearance. The truth almost immediately struck him: there was a volcano amongst those mountains up which he was ascending; and it was the lava which had produced that desolation, and which, cold and hardened, formed the soil whereon he walked. It was now past midday; and he seated himself once more to repose his limbs, wearied with the fatigues of the ascent and overcome by the heat that was there intolerable. At the distance of about two hundred yards on his right was a solitary tree, standing like a sign to mark the tomb of nature's vegetation. Upon this tree his eyes were fixed listlessly, and he was marveling within himself how that single scion of the forest could have been spared, when the burning lava, whenever the eruption might have taken place, had hurled down and reduced to cinders its verdant brethren. Suddenly his attention was more earnestly riveted upon the dense and wide-spreading foliage of that tree; for the boughs were shaken in an extraordinary manner, and something appeared to be moving about amongst the canopy of leaves. In another minute a long, unmistakable, appalling object darted forth--a monstrous snake--suspending itself by the tail to one of the lower boughs, and disporting playfully with its hideous head toward the ground. Then, with a sudden coil, it drew itself back into the tree, the entire foliage of which was shaken with the horrible gambolings of the reptile.
