He did not think of shooting at the Piutes; they, however, recovering from their shock, evidently feared the ambush, for they swiftly drew up the slope and passed out of sight. The frightened horses below whistled and tramped along the lower level, finally vanishing. There was nothing left on the bare wall to prove to Shefford that it had been the scene of swift and tragic death. He leaned from his covert and peered over the rim. Hundreds of feet below he saw dark growths of pinyons. There was no sign of a pile of horses and men, and then he realized that he could not tell the number that had perished. The swift finale had been as stunning to him as if lightning had struck near him. Suddenly it flashed over him what state of suspense and torture Fay and Jane must be in at that very moment. And, leaping up, he ran out of the cedars to the slope behind and hurried down at risk of limb. The sun had set by this time. He hoped he could catch up with the party before dark. He went straight down, and the end of the slope was a smooth, low wall. The Indian must have descended with the horses at some other point. The cañon was about fifty yards wide and it headed under the great slope of Navajo Mountain. These smooth, rounded walls appeared to end at its low rim. Shefford slid down upon a grassy bank, and finding the tracks of the horses, he followed them. They led along the wall. As soon as he had assured himself that Nas Ta Bega had gone down the cañon he abandoned the tracks and pushed ahead swiftly. He heard the soft rush of running water. In the center of the cañon wound heavy lines of bright-green foliage, bordering a rocky brook. The air was close, warm, and sweet with perfume of flowers. The walls were low and shelving, and soon lost that rounded appearance peculiar to the wind-worn slopes above. Shefford came to where the horses had plowed down a gravelly bank into the clear, swift water of the brook. The little pools of water were still muddy. Shefford drank, finding the water cold and sweet, without the bitter bite of alkali. He crossed and pushed on, running on the grassy levels. Flowers were everywhere, but he did not notice them particularly. The cañon made many leisurely turns, and its size, if it enlarged at all, was not perceptible to him yet. The rims above him were perhaps fifty feet high. Cottonwood-trees began to appear along the brook, and blossoming buck-brush in the corners of wall. He had traveled perhaps a mile when Nas Ta Bega, appearing to come out of the thicket, confronted him. “Hello!” called Shefford. “Where're Fay--and the others?” The Indian made a gesture that signified the rest of the party were beyond a little way. Shefford took Nas Ta Bega's arm, and as they walked, and he panted for breath, he told what had happened back on the slopes.
