“No one but God and I knows what is in my heart,” she thought. “But that’s not true, that’s not true. For I don’t know.” The last echo of the Arab’s song fainted on the blazing air. Surely it had changed now. Surely, as he turned into the shadows of the palms, he was singing, “No one but God knows what is in my heart.” Yes, he was singing that. “No one but God--no one but God.” Count Anteoni looked down at her. She did not notice it, and he kept his eyes on her for a moment. Then he turned to the desert again. By degrees, as she watched, Domini became aware of many things indicative of life, and of many lives in the tremendous expanse that at first had seemed empty of all save sun and mystery. She saw low, scattered tents, far-off columns of smoke rising. She saw a bird pass across the blue and vanish towards the mountains. Black shapes appeared among the tiny mounds of earth, crowned with dusty grass and dwarf tamarisk bushes. She saw them move, like objects in a dream, slowly through the shimmering gold. They were feeding camels, guarded by nomads whom she could not see. At first she persistently explored the distances, carried forcibly by an _elan_ of her whole nature to the remotest points her eyes could reach. Then she withdrew her gaze gradually, reluctantly, from the hidden summoning lands, whose verges she had with difficulty gained, and looked, at first with apprehension, upon the nearer regions. But her apprehension died when she found that the desert transmutes what is close as well as what is remote, suffuses even that which the hand could almost touch with wonder, beauty, and the deepest, most strange significance. Quite near in the river bed she saw an Arab riding towards the desert upon a prancing black horse. He mounted a steep bit of path and came out on the flat ground at the cliff top. Then he set his horse at a gallop, raising his bridle hand and striking his heels into the flanks of the beast. And each of his movements, each of the movements of his horse, was profoundly interesting, and held the attention of the onlooker in a vice, as if the fates of worlds depended upon where he was carried and how soon he reached his goal. A string of camels laden with wooden bales met him on the way, and this chance encounter seemed to Domini fraught with almost terrible possibilities. Why? She did not ask herself. Again she sent her gaze further, to the black shapes moving stealthily among the little mounds, to the spirals of smoke rising into the glimmering air. Who guarded those camels? Who fed those distant fires? Who watched beside them? It seemed of vital consequence to her that she should know. Count Anteoni took out his watch and glanced at it. “I am looking to see if it is nearly the hour of prayer,” he said. “When I am in Beni-Mora I usually come here then.” “You turn to the desert as the faithful turn towards Mecca?” “Yes. I like to see men praying in the desert.”
