to keep distant the winds and noises of the night; and by contrast it was strange, but quieting, to rest within walls, with a roof above; even though walls and roof were only interlacing twigs making a darker mesh against the star-scattered sky.
For myself, I was ill again; a fever increasing upon me, and my body very sore with boils and the rubbing of my sweaty saddle. When Nasir, without my prompting, had halted at the half-stage, I turned and thanked him warmly, to his astonishment. We were now on the limestone of the Shefa crest. Before us lay a great dark lava-field, and short of it a range of red and black banded sandstone cliffs with conical tops. The air on the high tableland was not so warm; and morning and evening there blew across us a free current which was refreshing after the suspended stillness of the valleys.
We breakfasted on our camel meat, and started more gaily the next morning down a gently-falling plateau of red sandstone. Then we came to the first break of surface, a sharp passage to the bottom of a shrub-grown, sandy valley, on each side of which sandstone precipices and pinnacles, gradually growing in height as we went down, detached themselves sharply against the morning sky. It was shadowed in the bottom, and the air tasted wet and decayed, as though sap was drying out into it. The edges of the cliffs about us were clipped strangely, like fantastic parapets. We wound on, ever deeper into the earth until, half an hour later, by a sharp corner, we entered Wadi Jizil, the main gutter of these sandstone regions, whose end we had seen near Hedia.
Jizil was a deep gorge some two hundred yards in width, full of tamarisk sprouting from the bed of drifted sand, as well as from the soft twenty-foot banks, heaped up wherever an eddy in flood or wind had laid the heavier dust under the returns of cliffs. The walls each side were of regular bands of sandstone, streaked red in many shades. The union of dark cliffs, pink floors, and pale green shrubbery was beautiful to eyes
