broad terrace with an alluvial plot of sand and gravel in its midst. The lava was a nearly clean floor of iron-red rock-cinders, over which were scattered fields of loose stone. The third and other steps ascended to the south of us: but we turned east, up Wadi Gara.
Gara had, perhaps, been a granite valley down whose middle the lava had flowed, slowly filling it, and arching itself up in a central heap. On each side were deep troughs, between the lava and the hillside. Rain water flooded these as often as storms burst in the hills. The lava flow, as it coagulated, had been twisted like a rope, cracked, and bent back irregularly upon itself. The surface was loose with fragments through which many generations of camel parties had worn an inadequate and painful track.
We struggled along for hours, going slowly, our camels wincing at every stride as the sharp edges slipped beneath their tender feet. The paths were only to be seen by the droppings along them, and by the slightly bluer surfaces of the rubbed stones. The Arabs declared them impassable after dark, which was to be believed, for we risked laming our beasts each time our impatience made us urge them on. Just before five in the afternoon, however, the way got easier. We seemed to be near the head of the valley, which grew narrow. Before us on the right, an exact cone-crater, with tidy furrows scoring it from lip to foot, promised good going; for it was made of black ash, clean as though sifted, with here and there a bank of harder soil, and cinders. Beyond it was another lava-field, older perhaps than the valleys, for its stones were smoothed, and between them were straths of flat earth, rank with weeds. In among these open spaces were Beduin tents, whose owners ran to us when they saw us coming; and, taking our headstalls with hospitable force, led us in.
They proved to be Sheikh Fahad el Hansha and his men: old and garrulous warriors who had marched with us to Wejh, and had been with Garland on that great occasion when his first automatic mine had
