Delay after delay took place in our starting, until nine at night, and then we moved unwillingly: but I was determined to get clear of Wejh somehow before morning. So we went four hours and slept. Next day we did two stages of five hours each, and camped at Abu Zereibat, in our old ground of the winter. The great pool had shrunk little in the two months, but was noticeably more salt. A few weeks later it was unfit to drink. A shallow well near by was said to afford tolerable water. I did not look for it, since boils on my back and heavy fever made painful the jolting of the camel, and I was tired.
Long before dawn we rode away, and having crossed Hamdh got confused in the broken surfaces of Agunna, an area of low hills. When day broke we recovered direction and went over a watershed steeply down into El Khubt, a hill-locked plain extending to the Sukhur, the granite bubbles of hills which had been prominent on our road up from Um Lejj. The ground was luxuriant with colocynth, whose runners and fruits looked festive in the early light. The Juheina said both leaves and stalks were excellent food for such horses as would eat them, and defended from thirst for many hours. The Ageyl said that the best aperient was to drink camel-milk from cups of the scooped-out rind. The Ateibi said that he was sufficiently moved if he just rubbed the juice of the fruit on the soles of his feet. The Moor Hamed said that the dried pith made good tinder. On one point however they were all agreed, that the whole plant was useless or poisonous as fodder for camels.
This talk carried us across the Khubt, a pleasant three miles, and through a low ridge into a second smaller section. We now saw that, of the Sukhur, two stood together to the northeast, great grey striated piles of volcanic rock, reddish coloured where protected from the burning of the sun and the bruising of sandy winds. The third Sakhara, which stood a little apart, was the bubble rock which had roused my curiosity. Seen from near by, it more resembled a huge football half-buried in the ground. It, too, was brown in colour. The south and east faces were quite
