and marks here and there in the soil told her that she was not the first to pass that way. "I wonder who it was?" she speculated. "Either Monk Bethune, or Vil Holland, or Lord Clendenning, I suppose. They all seem to be forever riding back and forth through the hills." At last she gained the summit, and pulled up to enjoy the view. Judging by the trampled buffalo grass that capped the divide, the rider who preceded her had also stopped. She glanced backward, and there, showing above the tops of the trees that covered the slope, stood her own cabin, looking tiny and far away, but with its every detail standing out with startling clearness. She could even see the ax standing where she had left it beside the door, and the box she had placed at the end of the log wall to take the place of the cupboard as a home for the pack rats. "Whoever it was could certainly keep track of my movements from here without the least risk of being discovered," she thought, "and if he had field glasses!" She blushed, and turned her eyes to survey the endless succession of peaks and passes and valleys that lay spread out over the sea of hills. "How in the world am I ever going to find one tiny little valley among all these?" she wondered. Her heart sank at the vastness of it all, and at her own helplessness, and the utter hopelessness of her stupendous task. "Oh, I can never, never do it," she faltered, "--never." And, instantly ashamed of herself, clenched her small, gloved fist. "I will do it! My daddy found his mine, and he didn't have any pictures to go by either. He just delved and worked for years and years--and at last he found it. I'd find it if there were twice as many hills and valleys. It may take me years--and I may find it to-day--just think! This very day I may ride into that little valley--or to-morrow, or the next day. It can't be far away. Mrs. Watts said daddy was always to be found within ten miles of the ranch." She headed her horse down the opposite slope that slanted at a much easier gradient than the one she had just ascended. The trees on this side of the divide were larger and the hillside gradually flattened into a broad, tilted plateau. She gave her horse his head and breathed deeply of the pine-laden air as the animal swung in beside a tiny creek that flowed smooth and black through the dusky silence of the pines whose interlacing branches, high above, admitted the sunlight in irregular splashes of gold. There was little under-brush and the horse followed easily along the creek, where here and there, in the softer soil of damp places, the girl could see the hoof marks of the rider who had crossed the divide. "I wonder whether it was he who watched me last night? There was someone, I could feel it."
