The country begins to exhibit decidedly a volcanic character, and from all the heights rise bare basaltic cones, while the lower part is covered with halfa. This character of the country seems to have been well understood by the Arabs, when they gave to these basins, surrounded by basaltic mounts, the name “Shʿabet,” which we have already seen given to the crater of the Tekút. Here, at a short distance on our left, we passed “another Shʿabet,” distinguished as “el Akhera.” At length we found an opening through the hilly chain on our right, behind an indented projection of the ridge called “Sennet el Osis,” and then suddenly changed our course from north-east to south-east. As soon as we had made the circuit of this mount, we obtained a view of the highest points of the Tarhóna, and directed our course by one of them, Mount Bíbel, which is said to be sometimes visible from Tripoli. Tales of deadly strife are attached to some localities hereabouts; and, according to our guide, the torrent which we crossed beyond Wady Ruéra poured down, some years ago, a bloody stream. But at present the scene wants life, the Kasr Kuséba, situated on the apex of a cone, being almost the only dwelling-place which we had seen for five hours. Life has fled from these fertile and pleasant regions; and the monotonous character which they at present exhibit necessarily impresses itself on the narrative of the traveller. At length, after having entered the gorges of the mountains, we reached the encampment of the Merabetín Bu-ʿAáysha, and pitched our tent at a short distance from it. These people have considerable herds of camels and sheep; as for cattle, there are at present very few in the whole regency of Tripoli, except in the neighbourhood of Ben-gházi. Their chief, ʿAbdallah, who lives in Tripoli, is much respected. The valleys and plains hereabouts, when well saturated with rain, produce a great quantity of corn, but they are almost entirely destitute of trees. Having been thoroughly drenched to-day by heavy showers, we were in a very uncomfortable condition at its close.
