Meanwhile the other rider stood by, vacantly holding the halters, waiting perhaps for the Harb to finish watering their herd before taking his turn. The young lord cried What is it, Mustafa? Water them at once'. The servant came up to say dismally, They will not let me'. 'God's mercy!' shouted his master furiously, as he scrambled to his feet and hit the unfortunate Mustafa three or four sharp blows about the head and shoulders with his riding-stick 'Go and ask them.' Mustafa looked hurt, astonished, and angry as though he would hit back, but thought better of it, and ran to the well.

The Harb, shocked, in pity made a place for him, and let his two camels drink from their water-trough. They whispered, 'Who is he?' and Mustapha said, 'Our Lord's cousin from Mecca'. At once they ran and untied a bundle from one of their saddles, and spread from it before the two riding camels fodder of the green leaves and buds of the thorn trees. They were used to gather this by striking the low bushes with a heavy staff, till the broken tips of the branches rained down on a cloth stretched over the ground beneath.

The young Sherif watched them contentedly. When his camel had fed, he climbed slowly and without apparent effort up its neck into the saddle, where he settled himself leisurely, and took an unctuous farewell of us, asking God to requite the Arabs bountifully. They wished him a good journey; and he started southward, while Abdulla brought our camels, and we went off northward. Ten minutes later I heard a chuckle from old Tafas, and saw wrinkles of delight between his grizzled beard and moustache.

'What is upon you, Tafas?' said I.

'My Lord, you saw those two riders at the well?'

'The Sherif and his servant?'

'Yes; but they were Sherif Ali ibn el Hussein of Modhig, and his cousin, Sherif Mohsin, lords of the Harith, who are blood enemies of the Masruh. They feared they would be delayed or driven off the water if the Arabs knew them. So they pretended to be master and servant from Mecca. Did you see how Mohsin raged when Ali beat him? Ali is a devil. While only eleven years old he escaped from his father's house to his uncle, a robber of pilgrims by trade; and with him he lived by his hands for many months, till his father caught him. He was with our lord Feisal from the first day's battle in Medina, and led the Ateiba in the plains round Aar and Bir Derwish. It was all camel-fighting; and Ali would have no man with him who could not do as he did, run beside his camel, and leap with one hand into the saddle, carrying his rifle. The children of Harith are children of battle.' For the first time the old man's mouth was full of words.

CHAPTER XI

While 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.

Men have looked upon the desert as barren land, the free holding of whoever chose; but in fact each hill and valley in it had a man who was its acknowledged owner and would quickly assert the right of his family or clan to it, against aggression. Even the wells and trees had their masters, who allowed men to make firewood of the one and drink of the other freely, as much as was required for their need, but who would instantly check anyone trying to turn the property to account and to exploit it or its products among others for private benefit. The desert was held in a crazed communism by which Nature and the elements were for the free use of every known friendly person for his own purposes and no more. Logical outcomes were the reduction of this licence to privilege by the men of the desert, and their hardness to strangers unprovided with introduction or guarantee, since the common security lay in the common responsibility of kinsmen. Tafas, in his own country, could bear the burden of my safe-keeping lightly.

The valleys were becoming sharply marked, with clean beds of sand and shingle, and an occasional large boulder brought down by a flood. There were many broom bushes, restfully grey and green to the eye, and good for fuel, though useless as pasture. We ascended steadily till we rejoined the main track of the pilgrim road. Along this we held our way till sunset, when we came into sight of the hamlet of Bir el Sheikh. In the first dark as the supper fires were lighted we rode down its wide open street and halted. Tafas went into one of the twenty miserable huts, and in a few whispered words and long silences bought flour, of which with water he kneaded a dough cake two inches thick and eight inches across. This he buried in the ashes of a brushwood fire, provided for him by a Subh woman whom he seemed to know. When the cake was warmed he drew it out of the fire, and clapped it to shake off the dust; then we shared it together, while Abdulla went away to buy himself tobacco.

They told me the place had two stone-lined wells at the bottom of the southward slope, but I felt disinclined to go and look at them, for the long ride that day had tired my unaccustomed muscles, and the heat of the plain had been painful. My skin was blistered by it, and my eyes ached with the glare of light striking up at a sharp angle from the silver sand, and from the shining pebbles. The last two years I had spent in Cairo, at a desk all day or thinking hard in a little overcrowded office full of distracting noises, with a hundred rushing things to say, but no bodily need except to come and go each day between office and hotel. In consequence the novelty of this change was severe, since time had not been given me gradually to accustom myself to the pestilent beating of the Arabian sun, and the long monotony of camel pacing. There was to be another stage tonight, and a long day to-morrow before Feisal's camp would be reached.
