Men sleeping on benches in the court of the mosque, under arches in the wall, waked and drank water out of bulging goatskins, hanging from huge hooks. Pilgrims washed their feet in the black marble basin of the trickling fountain, for soon it would be time for moghreb, the prayer of the evening.

Far away, eighteen miles distant across the sands, she could see the twenty thousand domes of Oued Tolga, the desert city which had taken its name from the older Zaouïa, and the oued or river which ran between the sacred edifice on its golden hill, and the ugly toub-built village, raised above danger of floods on a foundation of palm trunks.

Far away the domes of the desert city shimmered like white fire in the strange light that hovers over the Sahara before the hour of sunset. Behind those distant, dazzling bubbles of unearthly whiteness, the valley-like oases of the southern desert, El Souf, dimpled the yellow dunes here and there with basins of dark green. Near by, a little to the left of the Zaouïa hill, such an oasis lay, and the woman on the white roof could look across a short stretch of sand, down into its green depths. She could watch the marabout's men repairing the sloping sand-walls with palm trunks, which kept them from caving in, and saved the precious date-palms from being engulfed in a yellow tide. It was the marabout's own private oasis, and brought him in a large income every year. But everything was the marabout's. The woman on the roof was sick to death of his riches, his honours, his importance, for she was the marabout's wife; and in these days she loved him as little as she loved the orange garden he had given her, and all the things that were hers because she was his.

It was very still in the Zaouïa of Oued Tolga. The only sound was the droning of the boys' voices, which came faintly from behind iron window-gratings below, and that monotonous murmur emphasized the silence, as the humming of bees in a hive makes the stillness of a garden in summer more heavy and hot.

No noises came from the courts of the women's quarters, or those of the marabout's guests, and attendants, and servants; not a voice was raised in that more distant part of the Zaouïa where the students lived, and where the poor were lodged and fed for charity's sake. No doubt the village, across the narrow river in its wide bed, was buzzing with life at this time of day; but seldom any sound there was loud enough to break the slumberous silence of the great Zaouïa. And the singing of the men in the near oasis who fought the sand, the groaning of the well-cords woven of palm fibre which raised the buckets of hollowed palm-trunks, was as monotonous as the recitation of the Koran. The woman had heard it so often that she had long ago ceased to hear it at all.

She looked westward, across the river to the ugly village with the dried palm-leaves on its roofs, and far away to the white-domed city, the dimpling oases and the mountainous dunes that towered against a flaming sky; then eastward, towards the two vast desert lakes, or chotts, one of blue water, the other of saltpetre, which looked bluer than water, and had pale edges that met the sand like snow on gold. Above the lake of water suddenly appeared a soaring line of white, spreading and mounting higher, then turning from white to vivid rose. It was the flamingoes rising and flying over the chott, the one daily phenomenon of the desert which the woman on the roof still loved to watch. But her love for the rosy line against the blue was not entirely because of its beauty, though it was startlingly beautiful. It meant something for which she waited each evening with a passionate beating of her heart under the orange-coloured robe and the chain of amber beads. It meant sunset and the coming of a message. But the doves on the green tiled minaret of the Zaouïa mosque had not begun yet to dip and wheel. They would not stir from their repose until the muezzin climbed the steps to call the hour of evening prayer, and until they flew against the sunset the message could not come.

She must wait yet awhile. There was nothing to do till the time of hope for the message. There was never anything else that she cared to do through the long days from sunrise to sunset, unless the message gave her an incentive when it came.

In the river-bed, the women and young girls had not finished their washing, which was to them not so much labour as pleasure, since it gave them their opportunity for an outing and a gossip. In the bed of shining sand lay coloured stones like jewels, and the women knelt on them, beating wet bundles of scarlet and puce with palm branches. The watcher on the roof knew that they were laughing and chattering together though she could not hear them. She wondered dimly how many years it was since she had laughed, and said to herself that probably she would never laugh again, although she was still young, only twenty-eight. But that was almost old for a woman of the East. Those girls over there, wading knee-deep in the bright water to fill their goatskins and curious white clay jugs, would think her old. But they hardly knew of her existence. She had married the great marabout, therefore she was a marabouta, or woman saint, merely because she was fortunate enough to be his wife, and too highly placed for them to think of as an earthly woman like themselves. What could it matter whether such a radiantly happy being were young or old? And she smiled a little as she imagined those poor creatures picturing her happiness. She passed near them sometimes going to the Moorish baths, but the long blue drapery covered her face then, and she was guarded by veiled negresses and eunuchs. They looked her way reverently, but had never seen her face, perhaps did not know who she was, though no doubt they had all heard and gossipped about the romantic history of the new wife, the beautiful Ouled Naïl, to whom the marabout had condescended because of her far-famed, her marvellous, almost incredible loveliness, which made her a consort worthy of a saint.

The river was a mirror this evening, reflecting the sunset of crimson and gold, and the young crescent moon fought for and devoured, then vomited forth again by strange black cloud-monsters. The old brown palm-trunks, on which the village was built, were repeated in the still water, and seemed to go down and down, as if their roots might reach to the other side of the world.

Over the crumbling doorways of the miserable houses bleached skulls and bones of animals were nailed for luck. The red light of the setting sun stained them as if with blood, and they were more than ever disgusting to the watcher on the white roof. They were the symbols of superstitions the most Eastern and barbaric, ideas which she hated, as she was beginning to hate all Eastern things and people.
