Starting at an early hour, we ascended very rugged ground, the rocky ridges on both sides often meeting together and forming irregular defiles. After a march of five miles and a half, we reached the highest elevation, and obtained a view over the whole district, which, being sprinkled as it were with small granitic mounds, had a very desolate appearance; but in the distance to our left an interesting mountain- group was to be seen, of which the accompanying sketch will give some idea. [Illustration] Having crossed several small valleys, we reached, a little before ten o’clock, one of considerable breadth, richly overgrown with herbage, and exhibiting evident traces of a violent torrent which had swept over it the day before, while with us but little rain had fallen. It is called Jínninau, and improved as we advanced, our path sometimes keeping along it, sometimes receding to a little distance; in some places the growth of the trees, principally the _Balanites_ or abórak, was indeed splendid and luxuriant. Unfortunately we had not sufficient leisure and mental ease to collect all the information which, under more favourable circumstances, would have been within our reach. Thus, I learnt that magnetic ironstone was found in the mountains to our left. After noon the valley divided into three branches, the easternmost of which is the finest and richest in vegetation, while the western one, called Tiyút, has likewise a fine supply of trees and herbage; we took the middle one, and a little further on, where it grew narrower, encamped. It was a very pretty and picturesque camping-ground. At the foot of our tents was a rocky bed of a deep and winding torrent bordered by most luxuriant talha- and abórak-trees (_Balanites Ægyptiaca_), and forming a small pond where the water, rushing down from the rocks behind, had collected; the fresh green of the trees, enlivened by recent rains, formed a beautiful contrast with the dark-yellowish colour of the rocks behind. Notwithstanding our perilous situation, I could not help straying about, and found, on the blocks over the tebki or pond, some coarse rock-sculptures representing oxen, asses, and a very tall animal which, according to the Kél-owí, was intended to represent the giraffe. While I was enjoying the scenery of the place, Dídi stept suddenly behind me, and tried to throw me down, but not succeeding, laid his hands from behind upon the pistols which I wore in my belt, trying, by way of experiment, whether I was able to use them notwithstanding his grasp; but turning sharply round, I freed myself from his hold, and told him that no effeminate person like himself should take me. He was a cunning and insidious fellow; and I trusted him the least of our Kél-owí friends. Ánnur warned us that the freebooters intended to carry off the camels that we ourselves were riding, in the night; and it was fortunate that we had provided for the emergency, and were able to fasten them to strong iron rings.
