 NCE we halted and began to feel that a great depression lay in front of us; but not till two in the afternoon after we had crossed a basalt outcrop did we look out over a trough fifteen miles across, which was Wadi Hamdh, escaped from the hills. On the north-west spread the great delta through which Hamdh spilled itself by twenty mouths; and we saw the dark lines, which were thickets of scrub in the flood channels of the dried beds, twisting in and out across the flat from the hill-edge beneath us, till they were lost in the sun-haze thirty miles away beyond us to our left, near the invisible sea. Behind Hamdh rose sheer from the plain a double hill, Jebel Raal: hog-backed but for a gash which split it in the middle. To our eyes, sated with small things, it was a fair sight, this end of a dry river longer than the Tigris; the greatest valley in Arabia, first understood by Doughty, and as yet unexplored; while Raal was a fine hill, sharp and distinctive, which did honour to the Hamdh.

Full of expectation we rode down the gravel slopes, on which tufts of grass became more frequent, till at three o’clock we entered the Wadi itself. It proved a bed about a mile wide, filled with clumps of asla bushes, round which clung sandy hillocks each a few feet high. Their sand was not pure, but seamed with lines of dry and brittle clay, last indications of old flood levels. These divided them sharply into layers, rotten with salty mud and flaking away, so that our camels sank in, fetlock-deep, with a crunching noise like breaking pastry. The dust rose up in thick clouds, thickened yet more by the sunlight held in them; for the dead air of the hollow was a-dazzle.

The ranks behind could not see where they were going, which was difficult for them, as the hillocks came closer together, and the river bed split into a maze of shallow channels, the work of partial floods year after year. Before we gained the middle of the valley everything was overgrown by brushwood, which sprouted sideways from the mounds and laced one to another with tangled twigs as dry, dusty and brittle as old bone. We tucked in the streamers of our gaudy saddle-bags, to prevent their being jerked off by the bushes, drew cloaks tight over our clothes, bent our heads down to guard our eyes and crashed through like a storm amongst reeds. The dust was blinding and choking, and the snapping of the branches, grumbles of the camels, shouts and laughter of the men, made a rare adventure.
