HILE he spoke we scoured along the dazzling plain, now nearly bare of trees, and turning slowly softer under foot. At first it had been grey shingle, packed like gravel. Then the sand increased and the stones grew rarer, till we could distinguish the colours of the separate flakes, porphyry, green schist, basalt. At last it was nearly pure white sand, under which lay a harder stratum. Such going was like a pile-carpet for our camels' running. The particles of sand were clean and polished, and caught the blaze of sun like little diamonds in a reflection so fierce, that after a while I could not endure it. I frowned hard, and pulled the head-cloth forward in a peak over my eyes, and beneath them, too, like a beaver, trying to shut out the heat which rose in glassy waves off the ground, and beat up against my face. Eighty miles in front of us, the huge peak of Rudhwa behind Yenbo was looming and fading in the dazzle of vapour which hid its foot. Quite near in the plain rose the little shapeless hills of Hesna, which seemed to block the way. To our right was the steep ridge of Beni Ayub, toothed and narrow like a saw-blade, the first edge of the sheaf of mountains between the Tehama and the high scarp of the tableland about Medina. These Tareif Beni Ayub fell away on their north into a blue series of smaller hills, soft in character, behind which lofty range after range in a jagged stairway, red now the sun grew low, climbed up to the towering central mass of Jebel Subh with its fantastic granite spires.

A little later we turned to the right, off the pilgrim road, and took a short cut across gradually rising ground of flat basalt ridges, buried in sand till only their topmost piles showed above the surface. It held moisture enough to be well grown over with hard wiry grass and shrubs up and down the slopes, on which a few sheep and goats were pasturing. There Tafas showed me a stone, which was the limit of the district of the Masruh, and told me with grim pleasure that he was now at home, in his tribal property, and might come off his guard.
