“That night there was moon. Mademoiselle could not sleep. She lay in her narrow bed and thought of the figure in the mirage, while the moonbeams stole in between the tent pegs to keep her company. She thought of second sight, of phantoms, and of wraiths. Was this riding Arab, whom she alone could see, a phantom of the Sahara, mysteriously accompanying the caravan, and revealing himself to her through the medium of the mirage as if in a magic mirror? She turned restlessly upon her pillow, saw the naughty moonbeams, got up, and went softly to the tent door. All the desert was bathed in light. She gazed out as a mariner gazes out over the sea. She heard jackals yelping in the distance, peevish in their insomnia, and fancied their voices were the voices of desert demons. As she stood there she thought of the figure in the mirage, and wondered if mirage ever rises at night—if, by chance, she might see it now. And, while she stood wondering, far away across the sand there floated up a silvery haze, like a veil of spangled tissue—exquisite for a ball robe, she said long after!—and in this haze she saw again the phantom Arab galloping upon his horse. But now he was clear in the moon. Furiously he rode, like a thing demented in a dream, and as he rode he looked back over his shoulder, as if he feared pursuit. Mademoiselle could see his fierce eyes, like the eyes of a desert eagle that stares unwinking at the glaring African sun. He urged on his fleet horse. She could hear now the ceaseless thud of its hoofs upon the hard sand as it drew nearer and nearer. She could see the white foam upon its steaming flanks, and now at last she knew that the burden which the Arab bore across his saddle and supported with his arms was a woman. Her robe flew out upon the wind; her dark, loose hair streamed over the breast of the horseman; her face was hidden against his heart; but mademoiselle saw his face, uttered a cry, and shrank back against the canvas of the tent. “For it was the face of the Spahi who had ridden in the procession of the Governor—of the Spahi to whom she had thrown the roses from the balcony of Algiers. “As she cried out the mirage faded, the Arab vanished, the thud of the horse’s hoofs died in her ears, and Tahar, the dragoman, glided round the tent, and stood before her. His eyes gleamed in the moonlight like ebon jewels. “‘Hush!’ he whispered, ‘mademoiselle sees the mirage?’ “Mademoiselle could not speak. She stared into the eyes of Tahar, and hers were dilated with wonder. “He drew nearer to her. “‘Mademoiselle has seen again the horseman and his burden.’ “She bowed her head. All things seemed dream-like to her. Tahar’s voice was low and monotonous, and sounded far away. “‘It is fate,’ he said. He paused, gazing upon her. “‘In the tents they all sleep,’ he murmured. ‘Even the watchman sleeps, for I have given him a powder of hashish, and hashish gives long dreams—long dreams.’
