 collected little mounds about their roots, and the eddies of the sea-winds scooped hollows in the intervening spaces. Camels appeared not sure-footed in the dark, and the starlit sand carried little shadow, so that hummocks and holes were difficult to see. Before midnight we halted, and I rolled myself tighter in my cloak, and chose a hollow of my own size and shape, and slept well in it till nearly dawn.

As soon as he felt the air growing chill with the coming change, Tafas got up, and two minutes later we were swinging forward again. An hour after and it grew bright, as we climbed a low neck of lava drowned nearly to the top with blown sand. This joined a small flow near the shore to the main Hejaz lava-field, whose western edge ran up upon our right hand, and caused the coast road to lie where it did. The neck was stony, but brief: on each side the blue lava humped itself into low shoulders, from which, so Tafas said, it was possible to see ships sailing on the sea. Pilgrims had built cairns here by the road. Sometimes they were individual piles, of just three stones set up one above the other: sometimes they were common heaps, to which any disposed passer-by might add his stone—not reasonably nor with known motive, but because others did, and perhaps they knew.

Beyond the ridge the path descended into a broad open place, the Masturah, or plain by which Wadi Fura flowed into the sea. Seaming its surface with innumerable interwoven channels of loose stone, a few inches deep, were the beds of the flood water, on those rare occasions when there was rain in the Tareif and the courses raged like rivers to the sea. The delta here was about six miles wide. Down some part of it water flowed for an hour or two, or even for a day or two, every so many years. Underground there was plenty of moisture, protected by the overlying sand from the sun-heat; and thorn trees and loose scrub profited by it and flourished. Some of the trunks were a foot through: their height might be twenty feet. The trees and bushes stood somewhat apart, in clusters, their lower branches cropped by the hungry camels. So they looked cared for, and had a premeditated air, which felt strange in the wilderness, more especially as the Tehama hitherto had been a sober bareness.

Two hours up-stream, so Tafas told me, was the throat where Wadi Fura issued from the last granite hills, and there had been built
