REJOICINGS IN PIERRE'S FAMILY.

anxiety and hard riding, they came, to their great joy, upon the "trail" of the party, which they had since followed up steadily.

Those only, who have experienced the warm cordiality that grows up between comrades in wild and adventurous expeditions of the kind, can picture to themselves the hearty cheering with which the stragglers were welcomed to the camp. Every one crowded round them to ask questions, and to hear the story of their mishaps; and even the squaw of the moody half-breed, Pierre Dorion, forgot the sternness of his domestic rule, and the conjugal discipline of the cudgel, in her joy at his safe

return.

R. HUNT and his party were now on the skirts of the Black Hills, or Black Mountains, as they are sometimes called; an extensive chain, lying about a hundred miles east of the Rocky Mountains, and stretching in a northeast direction from the south fork of the Nebraska, or Platte River, to the great north bend of the Missouri. The Sierra or ridge of the Black Hills, in fact, forms the dividing line between the waters of the Missouri and those of the Arkansas and the Mississippi, and gives rise to the Cheyenne, the Little Missouri, and several tributary streams of the Yellowstone.

The wild recesses of these hills, like those of the Rocky Mountains, are retreats and lurking-places for broken and predatory tribes, and it was among them

that the remnant of the Cheyenne tribe took refuge, as has been stated, from their conquering enemies, the Sioux.

The Black Hills are chiefly composed of sandstone, and in many places are broken into savage cliffs and precipices, and present the most singular and fantastic forms; sometimes resembling towns and castellated fortresses. The ignorant inhabitants of plains are prone to clothe the mountains that bound their horizon with fanciful and superstitious attributes. Thus the wandering tribes of the prairies, who often behold clouds gathering round the summits of these hills, and lightning flashing, and thunder pealing from them, when all the neighboring plains are serene and sunny, consider them the abode of the genii or thunder-spirits who fabricate storms and tempests. On entering their defiles, therefore, they often hang offerings on the trees, or place them on the rocks, to propitiate the invisible "lords of the mountains," and procure good weather and successful hunting; and they attach unusual significance to the echoes which haunt the precipices. This superstition may also have arisen, in part, from a natural phenomenon of a singular nature. In the most calm and serene weather, and at all times of the day or night, successive reports are now and then heard among these mountains, resembling the discharge of several pieces of artillery. Similar reports were heard by Messrs. Lewis and Clarke in the Rocky Mountains, which they say were attributed by the Indians to the

bursting of the rich mines of silver contained in the bosom of the mountains.

In fact, these singular explosions have received fanciful explanations from learned men, and have not been satisfactorily accounted for even by philosophers. They are said to occur frequently in Brazil. Vasconcelles, a 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 crystal; 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 mountain, endeav

oring 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 thunder-spirits, 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 impassible 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 preci
