We returned by a more northern path, which at first led us through a rather difficult rocky passage, but afterwards joined our path of yesterday. Overweg and I had no time to lose in preparing for our journey over the hammáda, or plateau, while Mr. Richardson was obliged, by the conduct of the ill-provided and ill-disciplined blacks who accompanied him, to follow us by night. We therefore got up very early next morning, but lost a good deal of time by the quarrels among our camel-drivers, who were trying, most unjustly, to reserve all the heavy loads for the camels of the inexperienced Tarki lad ʿAli Karámra, till they excited his indignation, and a furious row ensued. This youth, though his behaviour was sometimes awkward and absurd, excited my interest in several respects. He belonged to a family of Tawárek, as they are called, settled in Wady el Gharbi, and was sent by his father to Tripoli with three camels, to try his chance of success, although members of that nation, with the exception of the Tinylkum, rarely visit Tripoli. He was slender and well-formed, of a glossy light-black complexion, and with a profile truly Egyptian; his manners were reserved, and totally different from those of his Fezzáni companions. At length we were under way, and began gradually to ascend along the strip of green which followed the shelving of the plateau into the valley, leaving the Roman sepulchre at some distance to our right. The flat Wady Labaerek, which is joined by Wady Shák, was still adorned with gattúf and rétem. It was not till we had passed the little hill called Lebaerek, and made another slight ascent, that we reached the real level of the terrible Hammáda; the ascent, or shelving ground, from Taboníye to this point being called el Mudhár mtʿa el Hammáda, and the spot itself, where the real Hammáda begins, Bú-safár, a name arising from the obligation which every pilgrim coming from the north, who has not before traversed this dreaded district, lies under, to add a stone to the heaps accumulated by former travellers.
