The sun, which was still high, was shining as only a Wyoming sun can shine, from out of a blue-vaulted canopy, flecked with fleecy clouds. Swinging from the tops of the sagebrush, or an occasional cottonwood, yellow-breasted meadowlarks were singing sweetly. At intervals a flock of curlews circled above the rider, uttering their sharp, plaintive cries; then they would drop to the ground and run rapidly to and fro on their frail, stilt-like legs, their long ungainly bills darting from side to side in search of food. Over the plains, from which Wade now turned, hundreds of red and white cattle, their hides as sleek as velvet, were grazing, singly and in scattered groups, as far as the eye could see. Toward its mouth, the valley was spotted with many fenced alfalfa fields, and traversed by irrigation ditches; while to the right, in the direction in which Wade now rode, rose the timber belt. A fresh, soft breeze, fragrant with the odor of clean, damp earth, rustled the leaves of the cottonwoods, some of which were of enormous size, as the horseman pushed his way farther into the shadow of the mountains. After a careful scrutiny, which satisfied him that the vicinity harbored no enemies, he dismounted, but still actuated by caution, kept the bridle reins looped over his wrist, as he searched for further evidence of gold. Unlike Santry, the ranchman was not trained in the ways of prospecting, and he began to regret that he had not allowed the foreman to accompany him. He followed what he thought were promising signs deeper into the silence of the tall timber, and finally dropped on his knees to make sure of some outcroppings of quartz near the base of a huge bowlder. He was so crouched when a sudden movement of his horse warned him of danger; but he had not time to arise before a crushing blow on the head, delivered from behind, shook him to the very marrow of his spine. With a low groan, he toppled over onto his face, senseless. "Have you got him?" Moran peered around the side of the bowlder, and smiled exultantly when he saw Wade's still figure. "Throw him across your saddle," he commanded, "and follow me." CHAPTER XV THE FIRST CLEW "Let's see!" Trowbridge reined in his horse and meditated, when he and Dorothy had covered several miles of their ride back to Crawling Water. "Jensen was shot around here somewhere, wasn't he?" "I think it was over there." She pointed with her quirt in the direction of a distant clump of jack-pines. "Why?" "Suppose we ride over and take a look at the spot." He smiled at her little shudder of repugnance. "We haven't any Sherlock Holmes in this country, and maybe we need one. I'll have a try at it. Come on!" In response to the pressure of his knees, the trained cow-pony whirled toward the jack-pines, and Dorothy followed, laughing at the idea that so ingenuous a man as Lem Trowbridge might possess the analytical gift of the trained detective.
