Having kept awhile along this picturesque ravine, we ascended its eastern side, and then followed the very edge of the steep, directly for the castle; but before reaching our tent we were obliged to cross a deep branch of the ravine. There was some little activity to-day about the castle, it being the market-day; but the market was really miserable, and the Turkish troops, exercising outside the castle, could ill supply the want of national welfare and prosperity. If a just and humane treatment were guaranteed to these tribes, even under a foreign rule, the country might still enjoy plenty and happiness. Most of the tribes westward from the Riaina—namely, the Zintán, who formerly were very powerful, and even at present hold some possessions as far as Fezzan, the Rujbán, the Fissátu, the Welád Shebel, the Selemát, the Arhebát, the Harába, the Génafíd, the Kabáw, and, the Nalúd, belong to the Berber race. With regard to the westernmost of these tribes, M. Prax on his way to Tuggúrt, has obtained some new information. After a friendly parting from the Kaimakám, we broke up our encampment near the kasr, in the afternoon, in order to continue our tour eastward along the varied border of the plateau, under the guidance of a faithful black servant of the governor, whose name was Barka. Having passed several smaller villages, we reached Um e’ Zerzán, a considerable village, situated on a round hill in the midst of a valley, ornamented with fine olive-trees, and surrounded by fine orchards. Um e’ Zerzán is well known among the mountaineers as a centre of rebellion. The whole neighbourhood is full of reminiscences of the late war, and about two miles in the rear of the village are the remains of strong walls called el Matarís, behind which the Arabs made some stand against the Turks. Having passed a solitary rustic dwelling surrounded with a thriving olive-plantation, we reached the ruins of a castle or village from which the Roman sepulchre, known among the Arabs by the name Enshéd e’ Sufét, burst suddenly upon our view. [Sidenote: Monday, February 11th.] After an extremely cold night on this high rocky ground, the thermometer in the morning indicating only 5° above freezing-point, with the dawn of day I mounted the hill opposite to the monument, commanding an extensive view.[11] It was a level tableland, uninterrupted by any higher eminence; but the landscape seemed to me highly characteristic, and I made a sketch of it.
