She was silent; the water rushed and murmured beside them, and the still bright atmosphere seemed to palpitate with some great mystery; were all barriers really disappearing and a new sweet understanding emerging from the challenge of their two opposing temperaments? Her heart trembled and beat fast at the thought; it was so wild, so improbable, so dangerously sweet. Then she made one great effort to master her emotions, to be herself. She schooled herself to meet his eyes again, with that new subtle sweetness of expression in them, that delicate understanding of her mood which frightened her! “Who am I that I should judge?” she said tremulously, with a charming smile, full of youth, simplicity, unconscious confession. Something in the very girlishness and purity of her face, and her unguarded mood smote Fox with sudden humility; he felt himself the veriest worldling and sinner compared with her. What right had he to thrust his life into hers? His hand closed over hers with unconscious force. “Who are you?” he repeated passionately, “my guardian angel.” Rose smiled; there were tears in her eyes but his emotion had the effect of crystallizing hers, she understood her own heart at last, and with a woman’s intuition began to hide it; she withdrew her hand gently and the horses went on. Neither spoke; both had been deeply moved and there was a new happiness in mere companionship. It was one of those rare moments, in the higher relations between man and woman, when a new situation emerges from the old, a more beautiful understanding is established, and the exquisite gentleness of his mood was a revelation to her of a phase of his character which she had only dimly perceived. The road had left the creek now and following the rising ground lay through a growth of stunted cedars; the stillness was broken suddenly by the full sweet note of a robin. Rose turned with kindling eyes. “Hark!” she exclaimed softly; “doesn’t that make you think of apple-blossoms? There must be periwinkles somewhere!” The spell was broken and he smiled, turning to look back for the singer. At the same moment Sandy stopped and pricked his ears. There was a full sound in the air, a throbbing and buzz of some machine and a big motor-car swung suddenly around the curve and bore down upon them. The road was narrow and both riders had to turn out on to the short turf beside the cedars. The car came on, and then abruptly slackening its speed it stopped a few yards beyond them and some one called to them. Rose looked back startled and met Margaret’s eyes. Mrs. White was leaning on the door of the car and beckoning to them, her great crimson hat flaming against the dark background. Meanwhile Louis Berkman had slipped down from the farther side and came up to Rose smiling, hat in hand. “I feel myself as fortunate as Balaam’s ass,” he said gayly, “since I, too, have met an angel in the way!”
