While they were scattered over the land, mounted men appeared on the horizon to the east, making towards the water. They came on too quickly to be honest, and fired at our herdsmen; but the rest of us ran at once upon the scattered reefs and knolls, shooting or shouting. Hearing us so many they drew off as fast as their camels would go; and from the ridge in the dusk we saw them, a bare dozen in all, scampering away towards the line. We were glad to see them avoid us so thoroughly. Auda thought they were a Shammar patrol.

At dawn we saddled up for the short stage to Diraa, the water pools of which Sharraf had told us. The first miles were through the grateful sand and scrub of Wadi Aish, and afterwards we crossed a simple lava flat. Then came a shallow valley, more full of sandstone pillars and mushrooms and pinnacles than anywhere yesterday. It was a mad country, of ninepins from ten to sixty feet in height. The sand paths between them were wide enough for one only, and our long column wound blindly through, seldom a dozen of us having common sight at once. This ragged thicket of stone was perhaps a third of a mile in width, and stretched like a red copse to right and left across our path.
