Frieda's heart beat rapidly. Her face was pale from excitement. She looked cautiously into the opening, thrust one small hand into it and drew out a round dish of hard, baked clay, engraved with queer, Indian characters. Frieda gave a shriek of delight, although she did not realize that she had accidentally discovered an important collection of Indian relics. But she was fascinated with the arrow heads and queer Indian dolls that she dug out a second later. In the midst of her search, Frieda heard a sound that made her heart stand still. At the head of the gorge, about a quarter of a mile away, there was a dense thicket of evergreens. From this direction came a cry of pain and terror. Frieda flew up to the ground above. "Jean, Jack!" she called. "What has happened? Is one of you hurt? Please come to me." Frieda gave the call, that was always the signal between the three ranch girls. "Oh-oo, Oh-ooo, Oh-oooo," ending in a shrill, drawn-out note, as she touched her lips with her fingers, three times in quick succession. Then she listened, but neither Jean nor Jack answered her. The ranch girls could hear sounds from afar off, as they had spent their lives in the open country. As Frieda ran forward a few steps, she caught the echo of light feet, flying along the ground. A girl came out of the woods, rushing toward her blindly. But Frieda could not tell who it was or guess what had happened. Was it Jean or Jack? CHAPTER III. FRIEDA AND THE OTHER GIRL. THE apparition drew near enough for Frieda to see that it was a stranger with straight black hair. She was barefoot and wore a short, ragged skirt, a bright red jacket, and a red scarf twisted around her throat. In her startled glance at the girl, Frieda beheld a pair of immense black eyes, set in a thin, pointed face, with cheeks flushed crimson, perhaps from the swiftness of her flight. Her breath came in short gasps. Frieda thought of a fawn she had once seen pursued by some hunters, with its great soft eyes transformed into staring pools of terror and its soft sides quivering as though its heart were breaking in its final effort to evade its pursuers. "Oh, what is it?" Frieda cried, with quick sympathy. The girl looked at her hopelessly and ran on. But Frieda now understood. An old Indian woman armed with a stick, trotted out of the screen of the trees. She was running more slowly but her face was terrifying. Her small black eyes were red with anger and she waved a long arm at the girl. [Illustration: FRIEDA FLUNG HERSELF VALIANTLY IN THE PATH OF THE INDIAN WOMAN.] Frieda wanted to help, but what could she do? "Jean! Jack!" she called again. She could see that the hunted girl had no chance of escaping. She was nearly dropping with exhaustion. There was no place for her to hide, for the plain stretched on, covered only with grass and low sage brush.
