About four o’clock in the afternoon we encamped in the Wadi Mukméda, near the sand-hills bordering its southern side, under the shade of a wild palm-bush. Close to it was very good water only two feet below the surface; but as the hole had only just been made, it contained much sulphuretted hydrogen. The following day we crossed several smaller valleys with a few palm-trees (but a larger grove adorned the Wadi Jemál), all belonging to one of our camel-drivers of the name of Bu Bakr. He also possessed here a magazine, built of bricks, and probably several centuries old, but entirely covered with sand, where he had deposited forty camel-loads of dates. They were of the kind called tefsirt, of very large size and exquisite taste, and were eagerly devoured by our people. After having refreshed ourselves for a moment, we went on, having just before us the very steepest ascent that occurs on the whole road. I was obliged to dismount from my beautiful Bu-Séfi in order to get him over it. This ridge being once behind us, we were told that all the “wár” was over; there were, however, still a few “difficult passes” before us. In the Wadi Gellah, which we next crossed, we found the footsteps of a flock of sheep and of a single camel, which latter animal finds plenty of food in this sandy district, and, at the shallow well in Wadi Uglah, is able to quench its thirst without the assistance of man. Thence we descended into Wadi Tigidéfa, where we encamped near a couple of palm-trees, the only ones in the wadi; a copious well of very good water was near them, overshadowed by a thick cluster of palm-bushes. It was altogether a very satisfactory camping- ground, except that it swarmed with camel-bugs, as such places in the desert generally do. [Sidenote: Wednesday, May 1st.]
