 where the cave and picture-writings were to be found. Now, however, we saw the whole summit completely covered with the same gigantic masses of rock and the same coarse rigid vegetation which had rendered our ascent so difficult, and made our proceeding for miles along similar ground quite out of the question. Our only remedy was to descend on the other side into the sandy plain which extended along its base. We first took a good view of the prospect which spread out before us,— a wide undulating plain covered with scattered trees and shrubs, with a yellow sandy soil and a brownish vegetation. Beyond this were seen, stretching out to the horizon, a succession of low conical and oblong hills, studding the distant plain in every direction. Not a house was to be seen, and the picture was one little calculated to impress the mind with a favourable idea of the fertility of the country or the beauty of tropical scenery. Our descent was very precipitous. Winding round chasms, creeping under overhanging rocks, clinging by roots and branches, we at length reached the bottom, and had level ground to walk on.

We now saw the whole side of the mountain, along its summit, split vertically into numerous rude columns, in all of which the action of the atmosphere on the different strata of which they were composed was more or less discernible. They diminished and increased in thickness as the soft and hard beds alternated, and in some places appeared like globes standing on pedestals, or the heads and bodies of huge giants. They did not seem to be prismatic, but to be the result of successive earthquake shocks, producing vertical cracks in cross directions, the action of the sun and rains then widening the fissures and forming completely detached columns.

As we proceeded along the sands we found the heat very oppressive. We had finished the water in our gourd, and knew not where to get more. Our Indian told us there was a spring halfway up the mountain, a little further on, but it night now have failed, as it was the height of the dry season.

We soon came in sight of the spot, and a group of Mauritia palms, which always grow in damp places, as well as some patches of brilliant green herbage, gave us hope. On reaching the palms we found a moist, boggy soil, but such a slow filtering of water among the weeds that it took nearly half an hour to fill our gourd. Seeing a mass of green at the very
