attained the limit of vegetation, when they saw but a few pines—whose gnarled and twisted branches exhibited scarcely a sign of verdure. Some small singing birds flew by them, and the plants they had observed in the course of their ascent thus far, are mentioned in the subjoined note.[1]
At this spot our travellers found a wide desert of black volcanic sand, covered with fragments of pumice. They were soon warned of approaching difficulties. The clouds gathered in thick masses around the top of the volcano portending a storm; and, scarcely had they retreated again to their tent, when it came down on them with all the mercilessness of a tropical hurricane. For several hours during the ensuing night the surrounding wastes were lit up with incessant flashes of the most brilliant lightning, shooting from the clouds above and below them, and at times even streaming horizontally along the wastes of dreary sand, crashing the branches of the forest and rending the stoutest pines. They seemed enveloped in flame—yet they had no protection from the fury of this storm of hail and thunder but a scanty cloth, thrown over the limb of a tree and pegged to the ground!
Thus passed the night until four o'clock. When day dawned, they found the mountain covered with snow, and the summit entirely enveloped in clouds. Nevertheless they resolved to proceed, and, with the greatest difficulty, prevailed on the Indians to accompany them.
For a league and a half farther, they advanced on horseback, but the pathway became so deep and yielding in the sand, that they were forced to dismiss their servants with the animals, and continue with the guides alone. The toil of ascending on foot now commenced, and they describe it as one of the most agonizing they ever underwent; sliding back half the distance they had made in advance at every footstep, and laboring with the increased circulation to such a degree that they could scarcely breathe. Yet they persevered resolutely for several hours, until the ill-shod Indians, whose feet were cut by the snow and sands, gave out entirely, and the Baron and Mr. Von Gerolt were forced to proceed wholly unattended. It was about this time that the sun broke out from the clouds for which (although they disregarded it then,) they paid dearly enough in the sequel.
At noon, after immense fatigue and exertions, they found themselves at
