At last,--thoroughly angry with her inability to control her mood, and half ashamed of the thoughts that forced themselves so insistently upon her; with her nerves and muscles craving the action that would bring the relief of physical weariness,--she determined to leave the more familiar ground, for the higher and less frequented waters of Fern Creek. Climbing out of the canyon, by the steep, almost stair-like trail on the San Bernardino side, she walked hard and fast to reach Lone Cabin by noon. But, before she had finished her lunch, she decided not to fish there, after all; but to go on, over the still harder trail to Burnt Pine on Laurel Creek, and, returning to the lower canyon by the Laurel trail, to work down Clear Creek on the way to her home, in the late afternoon and twilight. The trail up the almost precipitous wall of the gorge at Lone Cabin, and over the mountain spur to Laurel Creek, is one that calls for a clear head and a sure foot. It is not a path for the city bred to essay, save with the ready arm of a guide. But the hill-trained muscles and nerves of Sibyl Andrés gloried in the task. The cool-headed, mountain girl enjoyed the climb from which her city sisters would have drawn back in trembling fear. Once, at a point perhaps two-thirds of the height to the top, she halted. Her ear had caught a slight noise above her head, as a few pebbles rolled down the almost perpendicular face of the wall and bounded from the trail where she stood, into the depths below. For a few minutes, the girl, on the little, shelf-like path that was scarcely wider than the span of her two hands, was as motionless and as silent as the cliff itself; while, with her face turned upward, she searched with keen eyes the rim of the gorge; her free, right hand resting upon the butt of the revolver at her hip. Then she went on--not timidly, but neither carelessly; not in the least frightened, but still,--knowing that the spot was far from the more frequented paths,--with experienced care. As her head and shoulders came above the rim, she paused again, to search with careful eyes the vicinity of the trail that from this point leads for a little way down the knife-like ridge of the spur, and then, by easier stages, around the shoulder and the flank of the mountain, to Burnt Pine Camp. When no living object met her eye, and she could hear no sound save the lonely wind in the pines and the faint murmur of the stream in the gorge below, she took the few steps that yet remained of the climb, and seated herself for a moment's well-earned rest. Some small animal, she told herself,--a squirrel or a wood-rat, perhaps,--frightened at her approach, and scurrying hastily to cover, had dislodged the pebbles with the slight noise that she had heard.
