Over and over he said the words, chokingly, watering the hot sands with his tears. When the paroxysm had passed, it left him, weak and prone, still faintly crying his prayer into the sand, “O God, be merciful to me, a sinner.” When he had said over the words as long as his parched throat would let him, he became quiet. To his amazement, some new, strange peace had filled him. He took it for the peace of death. He was glad to think it was coming so gently—like a kind mother soothing him to his last sleep. His head on his arm, his whole tired body relaxing in this new restfulness, he opened his eyes and looked off to the south, idly scanning the horizon, his eyes level with the sandy plain. Then something made him sit quickly up and stare intently, his bared head craning forward. To the south, lying low, was a mass of light clouds, volatile, changing with opalescent lights as he looked. A little to the left of these clouds, while his head was on the sand, he thought his eyes had detected certain squared lines. Now he scanned the spot with a feverish eagerness. At first there was only the endless empty blue. Then, when his wonder was quite dead and he was about to lie down, there came a miracle of miracles,—a vision in the clear blue of the sky. And this time the lines were coherent. He, the dying sinner, had caught, clearly and positively for one awful second in that sky, the flashing impression of a cross. It faded as soon as it came, vanished while he gazed, leaving him in gasping, fainting wonder at the marvel. And then, before he could think or question himself, the sky once more yielded its vision; again that image of a cross stayed for a second in his eyes, and this time he thought there were figures about it. Some picture was trying to show itself to him. Still reaching his body forward, gazing fearfully, his aroused body pulsing swiftly to the wonder of the thing, he began to pray again, striving to keep his excitement under. “O God, have mercy on me, a sinner!”
