swung to the left under the great slope, and then presently it climbed to a higher bench. Here were brush and grass and huge patches of sage, so pungent that it stung Slone's nostrils. Then he went down again, this time to come to a clear brook lined by willows. Here the horses drank long and Slone refreshed himself. The sun had grown hot. There was fragrance of flowers he could not see and a low murmur of a waterfall that was likewise invisible. For most of the time his view was shut off, but occasionally he reached a point where through some break he saw towers gleaming red in the sun. A strange place, a place of silence, and smoky veils in the distance. Time passed swiftly. Toward the waning of the afternoon he began to climb to what appeared to be a saddle of land, connecting the canyon wall on the left with a great plateau, gold-rimmed and pine-fringed, rising more and more in his way as he advanced. At sunset Slone was more shut in than for several hours. He could tell the time was sunset by the golden light on the cliff wall again overhanging him. The slope was gradual up to this pass to the saddle, and upon coming to a spring, and the first pine-trees, he decided to halt for a camp. The mustang was almost exhausted. Thereupon he hobbled the horses in the luxuriant grass round the spring, and then unrolled his pack. Once as dusk came stealing down, while he was eating his meal, Nagger whistled in fright. Slone saw a gray, pantherish form gliding away into the shadows. He took a quick shot at it, but missed. "It's a lion country, all right," he said. And then he set about building a big fire on the other side of the grassy plot, so to have the horses between fires. He cut all the venison into thin strips, and spent an hour roasting them. Then he lay down to rest, and he said: "Wonder where Wildfire is to-night? Am I closer to him? Where's he headin' for?" The night was warm and still. It was black near the huge cliff, and overhead velvety blue, with stars of white fire. It seemed to him that he had become more thoughtful and observing of the aspects of his wild environment, and he felt a welcome consciousness of loneliness. Then sleep came to him and the night seemed short. In the gray dawn he arose refreshed. The horses were restive. Nagger snorted a welcome. Evidently they had passed an uneasy night. Slone found lion tracks at the spring and in sandy places. Presently he was on his way up to the notch between the great wall and the plateau. A growth of thick scrub-oak made travel difficult. It had not appeared far up to that saddle, but it was far. There were straggling pine-trees and huge rocks that obstructed his gaze. But once up he saw that the saddle was only a narrow ridge, curved to slope up on both sides. Straight before Slone and under him opened the canyon, blazing and glorious along the peaks and ramparts, where the rising sun struck, misty and smoky and shadowy down in those mysterious depths.
