Nothing in the march was normal or reassuring. We felt we were in an ominous land, incapable of life, hostile even to the passing of life, except painfully along such sparse roads as time had laid across its face. We were forced into a single file of weary camels, picking a hesitant way step by step through the boulders for hour after hour. At last Auda pointed ahead to a fifty-foot ridge of large twisted blocks, lying coursed one upon the other as they had writhed and shrunk in their cooling. There was the limit of lava; and he and I rode on together and saw in front of us an open rolling plain (Wadi Aish) of fine scrub and golden sand, with green bushes scattered here and there. It held a very little water in holes which someone had scooped after the rainstorm of three weeks ago. We camped by them and drove our unladen camels out till sunset, to graze for the first adequate time since Abu Raga.
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.
