We now pushed over to the eastward, but with precisely similar fortune. After an hour's scramble, at the risk of breaking our necks, we discovered that we had merely descended into a vast pit of black granite, with fine dust at the bottom, and whence the only egress was by the rugged path in which we had come down. Toiling again up this path, we now tried the northern edge of the hill. Here we were obliged to use the greatest possible caution in our manoeuvres, as the least indiscretion would expose us to the full view of the savages in the village. We crawled along, therefore, on our hands and knees, and, occasionally, were even forced to throw ourselves at full length, dragging our bodies along by means of the shrubbery. In this careful manner we had proceeded but a little way, when we arrived at a chasm far deeper than any we had yet seen, and leading directly into the main gorge. Thus our fears were fully confirmed, and we found ourselves cut off entirely from access to the world below. Thoroughly exhausted by our exertions, we made the best of our way back to the platform, and, throwing ourselves upon the bed of leaves, slept sweetly and soundly for some hours. For several days after this fruitless search we were occupied in exploring every part of the summit of the hill, in order to inform ourselves of its actual resources. We found that it would afford us no food, with the exception of the unwholesome filberts, and a rank species of scurvy grass which grew in a little patch of not more than four rods square, and would be soon exhausted. On the fifteenth of February, as near as I can remember, there was not a blade of this left, and the nuts were growing scarce; our situation, therefore, could hardly be more lamentable.[5] On the sixteenth we again went round the walls of our prison, in hope of finding some avenue of escape, but to no purpose. We also descended the chasm in which we had been overwhelmed, with the faint expectation of discovering, through this channel, some opening to the main ravine. Here, too, we were disappointed, although we found and brought up with us a musket. [Footnote 5: This day was rendered remarkable by our observing in the south several huge wreaths of the grayish vapour I have before spoken of.] On the seventeenth we set out with the determination of examining more thoroughly the chasm of black granite into which we had made our way in the first search. We remembered that one of the fissures in the sides of this pit had been but partially looked into, and we were anxious to explore it, although with no expectation of discovering here any opening.
