"And I've no time for explanations," she replied, with exasperating calmness; "you can think it over at your leisure." With a contemptuous "Humph!" Mr. Underwood left the house. After he had gone his sister sat for a while in deep thought, then, with a sigh, rose and went about her accustomed duties. She had been far more keen than her brother to observe the growing intimacy between her niece and Darrell, and she had seen some indications on the previous evening which troubled her, as much on Darrell's account as Kate's, for she had become deeply attached to the young man, and she well knew that her brother would not look upon him with favor as a suitor for his daughter. Meanwhile, Darrell, on reaching the office, found work and study alike impossible. The room seemed narrow and stifling; the medley of sound from the adjoining offices and from the street was distracting. He recalled the companions of his earlier days of pain and conflict,--the mountains,--and his heart yearned for their restful silence, for the soothing and uplifting of their solemn presence. Having left a brief note on Mr. Underwood's desk he closed his office, and, leaving the city behind him, started on foot up the familiar canyon road. After a walk of an hour or more he left the road, and, striking into a steep, narrow trail, began the ascent of one of the mountains of the main range. It still lacked a little of midday when he at last found himself on a narrow bench, near the summit, in a small growth of pines and firs. He stopped from sheer exhaustion and looked about him. Not a sign of human life was visible; not a sound broke the stillness save an occasional breath of air murmuring through the pines and the trickling of a tiny rivulet over the rocks just above where he stood. Going to the little stream he caught the crystal drops as they fell, quenching his thirst and bathing his heated brow; then, somewhat refreshed, he braced himself for the inevitable conflict. Slowly he paced up and down the rocky ledge, giving no heed to the passage of time, all his faculties centred upon the struggle between the inexorable demands of conscience on the one hand and the insatiate cravings of a newly awakened passion on the other. Vainly he strove to find some middle ground. Gradually, as his brain grew calm, the various courses of action which had at first suggested themselves to his mind appeared weak and cowardly, and the only course open to him was that of renunciation and of self-immolation. With a bitter cry he threw himself, face downward, upon the ground. A long time he lay there, till at last the peace from the great pitying heart of Nature touched his heart, and he slept on the warm bosom of Mother Earth as a child on its mother's breast.
