Zarzís consists of five separate villages—Kasr Bú ʿAli, Kasr Mwanza, Kasr Welád Mohammed, Kasr Welád Sʿaid, and Kasr Zawíya; the Bedouin in the neighbourhood belong to the tribe of the Akára. The plantation also is formed into separate date-groves. The houses are in tolerable repair and neatly whitewashed; but the character of order and well-being is neutralised by a good many houses in decay. Near the place there are also some Roman ruins, especially a cistern of very great length; and at some distance is the site of Medinet Ziyán, of which I have given a description in the narrative of my former journey. Besides the eight men attached to our five animals, we were joined here by four pilgrims and three Tripolitan traders; we thus made up a numerous body, armed with eight muskets, three blunderbusses, and fourteen pistols, besides several straight swords, and could venture upon the rather unsafe road to the south of the Lake of Bibán, though it would have been far more agreeable to have a few trustworthy people to rely on instead of these turbulent companions. Entering soon, behind the plantation of Zarzís, a long narrow sebkha, we were struck by the sterile and desolate character of the country, which was only interrupted by a few small depressed localities, where a little corn was cultivated. Keeping along this tract of country, we reached the north-western corner of the Lake of Bibán, or Bahéret el Bibán, after a little more than eight miles. This corner has even at the present day the common name of Khashm el kelb (the Dog’s Nose), while the former classical name of the whole lake, Sebákh el keláb, was only known to Tayyef, the more learned of my guides, who, without being questioned by me, observed that in former times towns and rich cornfields had been where the lake now is, but had been swallowed up by a sinking of the ground. The real basin has certainly nothing in common with a sebkha, which means a shallow hollow, incrusted with salt, which at times is dry and at others forms a pool; for it is a deep gulf or fiord of the sea, with which it is connected only by a narrow channel called Wád mtʿa el Bibán. The nature of a sebkha belongs at present only to its shores, chiefly to the locality called Makháda, which, indenting the country to a great distance, is sometimes very difficult to pass, and must be turned by a wide circuitous path, which is greatly feared on account of the neighbourhood of the Udérna, a tribe famous for its highway robberies. Having traversed the Makháda (which at present was dry) without any difficulty, we entered upon good arable soil, and encamped, after sunset, at about half a mile distance from a Bedouin encampment.
