face of the cliff, in such a manner, that by climbing it to its forks, and taking one of the latter, the opening might be reached. Putting a small mineral hammer in my pocket, I ascended this tree, and found the cave accessible. It yielded some wax-yellow and white translucent stalactites, and also very delicate white crystals of nitre. The dimensions of this cave were small, and but little higher than to enable a man to stand upright. In each of the caves of this glen which I entered, during a halt of several days in this vicinity, I looked closely about for fossil bones, but without success in any instance. The only article of this kind observed was the recent leg and foot bones and vertebra of the bos musarius, which appeared to be an inhabitant of the uppermost fissures in these calcareous cliffs, but I never saw the living species, although I ranged along their summits and bases, with my gun and hammer, at various hours. Some of the compact limestone in the bed of the creek exhibited a striped and jaspery texture. The wood-duck and the duck and mallard sometimes frequented this secluded stream, and it was a common resort for the wild turkey, at a certain hour in the evening. This bird seemed at such times to come in thirsty, from its ranges in quest of acorns on the uplands, and its sole object appeared to be to drink. Sitting in the mouth of our cave, we often had a fine opportunity to see flocks of these noisy and fine birds flying down from the cliffs, and perching on the trees below us. If they came to roost, as well as to slack their thirst, a supposition probable, this was an ill-timed movement, so long as we inhabited the glen, for they only escaped the claw and talons of one enemy, to fall before the fire-lock of the other. This bird, indeed, proved our best resource on the journey, for we travelled with too much noise and want of precaution generally, to kill the deer and elk, which, however, were abundant on the highland plains.
