The country here became very mountainous, and the ascent steep, till we reached a valley called by some of the Kél-owí the upper course of the valley of Tin-téllust. Having reached the crest of the elevation, we began to descend, first gradually along smaller valleys, afterwards more steeply into a deep ravine, while in the distance towards the south-west, above the lower hills, a ridge of considerable elevation became visible. Gradually the ravine widened, and became clothed with fine herbage. Here, to our great disappointment, the little Ánnur, Dídi, Fárreji, and several of the Tinýlkum (among them the intelligent and active Ibrahím) left us in order to reach their respective residences. Of course Ánnur ought to have seen us safe to the chief’s residence; but being without energy, he allowed our new companions, with whom we had not yet been able to become acquainted, to extort from us what they could, as the Fade-ang and the Aníslimen had done before. Keeping along some smaller valleys, we reached, about noon, a considerable pond of rain-water, where I watered my thirsty camel. Almost all the smaller valleys through which we passed incline towards the west. [Illustration] Much against our wish, we encamped a little after three o’clock P.M., in a widening of the valley Afís, near the southern cliffs (which had a remarkably shattered appearance), there being a well at some little distance. We had scarcely encamped when a troublesome scene was enacted, in the attempt to satisfy our escort, the men not being yet acquainted with us, and making importunate demands. But there was more turmoil and disturbance than real harm in it; and though half of the contents of a bale of mine were successfully carried off by the turbulent Mohammed, and a piece of scarlet cloth was cut into numberless small shreds in the most wanton manner, yet there was not much to complain of, and it was satisfactory to see Hámma (Ánnur’s son-in-law, and the chief of the escort) display the greatest energy in his endeavours to restore what was forcibly taken. _Wednesday, September 4._—We were glad when day dawned; but with it came very heavy rain, which had been portended last night by thickly accumulated clouds and by lightning. Rain early in the morning seems to be rather a rare phenomenon, as well in this country as all over Central Africa, if it be not in continuation of the previous night’s rain; and it was probably so on this occasion, rain having fallen during the whole night in the country around us.
