Natzie at the moment was still crouching close to the edge, gazing intently over, one little brown hand nervously grasping the branch of a stunted cedar, the other as nervously clutching the mirror. So utterly absorbed was she that the hiss of warning, or perhaps of hatred, with which Lola greeted the sudden coming of Angela, seemed to fall unnoted on her ears. Lola, her black eyes snapping and her lips compressed, glanced up at the white girl almost in fury. Natzie, paying no heed whatever to what was occurring about her, knelt breathless at her post, watching, eagerly watching. Then, slowly, they saw her raise her right hand, still cautiously holding the little mirror, face downward, and at sight of this the Apache boy could scarcely control his trembling, and Lola, turning about, spoke some furious words, in low, intense tone, that made him shrink back toward the screen. Then the wild girl glared again at Angela, as though the sight of her were unbearable, and, with as furious a gesture, sought to drive her, too, again to the refuge of the dark cleft, but Angela never stirred. Paying no heed to Lola, the daughter of the soldier gazed only at the daughter of the chief, at Natzie, whose hand was now level with the surface of the rock. The next instant, far to the northwest flashed a slender beam of dazzling light, another--another. An interval of a second or two, and still another flash. Angela could see the tiny, nebulous dot, like will-'o-the-wisp, dancing far over among the rocks across a gloomy gorge. She had never seen it before, but knew it at a glance. The Indian girl was signaling to some of her father's people far over toward the great reservation, and the tale she told was that danger menaced. Angela could not know that it told still more,--that danger menaced not only Natzie, daughter of one warrior chief, and the chosen of another now among their heroic dead--it threatened those whom she was pledged to protect, even against her own people. Somewhere down that deep and frowning rift to the southwest, Indian guides were leading their brethren on the trail of these refugees among the upper rocks. Somewhere, far over among the uplands to the northwest, other tribesfolk, her own kith and kin, were lurking, and these the Indian girl was summoning with all speed to her aid.
