Wednesday, August 21.—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.

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 stepped 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.

While keeping the first watch during the night, I was enabled by the splendid moonlight to address a few lines in pencil to my friends at home.

Thursday, August 22.—The Kél-owí having had some difficulty in finding their camels, we did not move at an early hour. To our great astonishment, we crossed the rocky bed of the torrent, and entered an irregular defile, where a little further on we passed another pond of rain-water. When at length we emerged from the rocks, we reached a very high level, whence we had a clear prospect over the country before us. Four considerable ranges of mountains were clearly distinguishable in the distance, forming an ensemble of which the accompanying sketch will give an idea. We then entered valleys clothed with a fine fresh verdure sprinkled with flowers, and with a luxuriant vegetation such as we had not seen before. The senna-plant (Cassia senna) appeared in tolerable quantity. Mountains and peaks were seen all around, in a great variety of forms; and at twenty minutes past nine we had a larger mountain mass on one side, from which a dry watercourse, marked by a broad line of herbage issued and crossed our route.

Having here allowed our camels a little feeding, we entered upon gravelly soil with projecting blocks of granite, and then went on ascending through a succession of small plains and valleys, till we reached Erazar-n-Gébi, among the splendid vegetation of which we first observed the abísga, or Capparis sodata, called siwák or lirák by the Arabs, an important bush, the currant-like fruit of which is not only eaten fresh, but also dried, and laid up in store, while the root affords that excellent remedy for the teeth which the Mohammedans, in imitation of their prophet, use to a great extent. The root, moreover, at least on the shores of the Tsád, by the process of burning, affords a substitute for salt. It is the most characteristic bush or tree of the whole region of transition between the desert and the fertile regions of Central Africa, between the twentieth and the fifteenth degree of northern latitude; and in the course of my travels I saw it nowhere of such size as on the northern bank of the Isa or Niger, between Timbúktu and Gágho, the whole ground which this once splendid and rich capital of the Songhay Empire occupied being at present covered and marked out by this celebrated bush. As for the camels, they like very well to feed for a short time upon its fresh leaves, if they have some other herb to mix with it; but eaten alone it soon becomes too bitter for them. In this valley the little berries were not yet ripe; but further on they were ripening, and afforded a slight but refreshing addition to our food.

Leaving the pleasant valley of Gébi by a small opening bordered with large blocks of granite, while peaks of considerable elevation were seen towering over the nearer cliffs, we entered another large valley, called Tághajít, but not quite so rich in vegetation, and encamped here, on an open space, a little after noon. The valley is important as being the first in the frontier region of Aïr or Asben where there is a fixed settlement—a small village of leathern tents, inhabited by people of the tribe of Fade-ang, who preserve a certain independence of the Kél-owí, while they acknowledge the supremacy of the Sultan of Ágades, a state of things of which I shall have occasion to say more in another place.
