Proceeding then, after midday we passed by a low white cone on our left, after which the valley, with its variety of vegetation, and animated as it was by numerous herds of goats, made a cheerful impression. Here the remains of stone dwellings became numerous; and further on we passed an entire village consisting of such houses, which, as I was distinctly informed, constituted in former times one of the principal settlements of the Kél-gerés, who were then masters of all the territory as far as the road to Ágades. The whole valley here formed a thick grove of dúm- palms; and stone houses, entire or in ruins, were scattered all about. About three o’clock in the afternoon we left it for an hour, traversing a rocky flat with a low ridge of basalt ranging on our right, when we descended again into the dúm-valley, which had been winding round on the same side, and encamped, at half-past four o’clock in the afternoon, in the midst of very wild and rank vegetation nourished by an immense torrent which occasionally rolls its floods along the channel, and which had left, on the stems of the baggarúwa-trees with which it was lined, evident traces of the depth which it may sometimes attain. The bed of the torrent was thickly overgrown with wild melons. Although there is no well in the neighbourhood, we were to stay here the two following days, in order to give the camels a good feed. A well, called Tánis-n-tánode, lies lower down the valley, but at a considerable distance. The valley itself runs south-westward: by some it is said to join the Erázar-n-Bargót; but this seems scarcely possible. Numerous flocks of wild pigeons passed over our heads the following morning, looking for water. The monotony of the halt was interrupted, in the course of the day, by the arrival of Hámma, who had been to Áfasás, and by that of Astáfidet, the young titular Kél-owí chief residing in Ásodi, among whose companions or followers was a very intelligent and communicative man of the name of El Hasár, who gave me a great deal of interesting information. All the eminences in the neighbourhood consist of basaltic formation. [Sidenote: Tuesday, December 24th.] We again moved on a little, following the rich valley, which in some places reminded me of the scenery of the Upper Nile, the only difference being that here the broad sandy bottom of the watercourse takes the place of the fine river in the scenery of Nubia. We made a short halt on the road, in order to supply ourselves with water from the well which I mentioned before. About noon, the fresh fleshy allwot, which had not been observed by us for several days, again appeared, to the great delight of the camels, which like it more than anything else, and, having been deprived of it for some time, attacked it with the utmost greediness. Two miles and a half further on, where the valley widened to a sort of irregular plain with several little channels, we encamped; there was a profusion of herbage all around.
