explanations from learned men, and have not been satisfactorily accounted for even by philosophers. They are said to occur frequently in Brazil. Vasconcelles, Jesuit father, describes one which he heard in the Sierra, or mountain region of Piratininga, and which he compares to the discharges of a park of artillery. The Indians told him that it was an explosion of stones. The worthy father had soon a satisfactory proof of the truth of their information, for the very place was found where a rock had burst and exploded from its entrails a stony mass, like a bomb-shell, and of the size of a bull's heart. This mass was broken either in its ejection or its fall, and wonderful was the internal organization revealed. It had a shell harder even than iron; within which were arranged, like the seeds of a pomegranate, jewels of various colors; some transparent as crystals; others of a fine red, and others of mixed hues. The same phenomenon is said to occur occasionally in the adjacent province of Guayra, where stones of the bigness of a man's hand are exploded, with a loud noise, from the bosom of the earth, and scatter about glittering and beautiful fragments that look like precious gems, but are of no value.

The Indians of the Orellanna, also, tell of horrible noises heard occasionally in the Paraguaxo, which they consider the throes and groans of the mountains, endeavoring to cast forth the precious stones hidden within its entrails. Others have endeavored to account for these discharges of "mountain artillery" on humbler principles; attributing them to the loud reports made by the disruption and fall of great masses of rock, reverberated and prolonged by the echoes; others, to the disengagement of hydrogen, produced by subterraneous beds of coal in a state of ignition. In whatever way this singular phenomenon may be accounted for, the existence of it appears to be well established. It remains one of the lingering mysteries of nature which throw something of a supernatural charm over her wild mountain solitudes; and we doubt whether the imaginative reader will not rather join with the poor Indian in attributing it to the thunderspirits, or the guardian genii of unseen treasures, than to any commonplace physical cause.

Whatever might be the supernatural influences among these mountains, the travellers found their physical difficulties hard to cope with. They made repeated attempts to find a passage through or over the chain, but were as often turned back by impassable barriers. Sometimes a defile seemed to open a practicable path, but it would terminate in some wild chaos of rocks and cliffs, which it was impossible to climb. The animals of these solitary regions were different from those they had been accustomed to. The black-tailed deer would bound up the ravines on their approach, and the bighorn would gaze fearlessly down upon them from some impending precipice, or skip playfully from rock to rock. These animals are only
