day to be in advance, as guide, but the temptation of small game, as we went up the valley, drew me aside, while Enobitti proceeded to select a suitable spot for the night's encampment. It was dark when I rejoined him, with my squirrel and pigeon hunt. He had confined himself closely to the trail. It soon led him out of the valley, up a long brushy ridge, and then through an open elevated pine grove, which terminated abruptly in a perpendicular precipice. Separated from this, at some eight hundred yards distance, stood a counter precipice of limestone rock, fretted out, into pinnacles and massy walls, with dark openings, which gave the whole the resemblance of architectural ruins. The stream that ran between these cliffs, was small, and it lay so deep and well embrowned in the shades of evening, that it presented vividly from this elevation, a waving bright line on a dark surface. Into this deep dark terrific glen the path led, and here we lit our fire, hastily constructed a bush camp, and betook ourselves, after due ablutions in the little stream, to a night's repose. The sky became rapidly overcast, before we had finished our meal, and a night of intense darkness, threatening a tempest, set in. As we sat by our fire, its glare upon huge beetling points of overhanging rocks, gave the scene a wild and picturesque cast; and we anticipated returning daylight with an anxious wish to know and see our exact locality. By the restless tramping of our horse, and the tinkling of his bell, we knew that he had found but indifferent picking. Daylight fulfilled the predictions of the evening. We had rain. It also revealed our position in this narrow, and romantic glen. A high wall of rocks, encompassed us on either hand, but they were not such as would have resulted in a volcanic country from a valley fissure. Narrow and deep as the glen was, it was at once apparent, that it was a valley of denudation, and had owed its existence to the wasting effects of the trifling stream within it, carrying away, particle by particle, the matter loosened by rains and frosts, and mechanical attrition. The cliffs are exclusively calcareous, and piled up, mason like, in horizontal layers. One of the most striking pictures which they presented, was found in the great number, size and variety of caves, which opened into this calcareous formation. These caves are of all sizes, some of them very large, and not a few of them situated at elevations above the floor of the glen, which forbade access.
