Another watershed conducted us to an open place where the Jeheina had ploughed some eight acres of the thin soil below a thicket of scrub. They said there were like it in the neighbourhood other fields, silent witnesses to the courage and persistence of the Arabs. It was called Wadi Chetf, and after it was another broken river of lava, the worst yet encountered. A shadowy path zigzagged across it. We lost one camel with a broken foreleg, the result of a stumble in a pothole; and the many bones which lay about showed that we were not the only party to suffer misfortune in the passage. However, this ended our lava, according to the guides, and we went thence forward along easy valleys with finally a long run up a gentle slope till dusk. The going was so good and the cool of the day so freshened me that we did not halt at nightfall, after our habit, but pushed on for an hour across the basin of Murrmiya into the basin of Wadi Ais, and there, by Tleih, we stopped for our last camp in the open.
