Seeing that she was leaving the big fellow behind, Lady Ebony whirled and halted, her front feet on a little hummock of grass. She waited until he was almost upon her, then she dodged past him and raced toward the mares. Again she outran him easily. The chestnut was filled with a wild desire to drive this fleet mare into his band and lead her away. He swerved and charged. She dodged and leaped past him. Lady Ebony was not trying to escape, she was giving play to the pulsing life within her. The coming of the chestnut stallion was something she had expected. She had been restless and nervous; now that restlessness was gone and she was filled with surging energy. The chestnut raced around the meadow again, trying to overtake Lady Ebony. He finally halted and stood with heaving sides. There was a savage light in his protruding eyes. Lady Ebony trotted toward him and stood nickering softly. She wanted to run some more. But the big stallion knew he was beaten. He was aware that he had made a great deal of noise, and noise was likely to bring riders with rifles. He turned and began driving his band off the meadow. As they trotted toward the narrow trail leading down into Shadow Canyon, Lady Ebony tossed her head and trotted after the band. The big stallion lunged at her with bared teeth. She humped her back and jigged up and down, warning him that if he nipped her she would lash out at him. He reached out to snap at her flanks and was met by two small hoofs which smashed against his wide chest. With a snort he leaped aside. He did not lunge at her again. She was much to his liking, a fighter and a swift runner. Lady Ebony fell in with the mares and the band moved down into the deep, green twilight of the canyon. They kept going until they reached the bottom. There they paused, crowding to the edge of the river, thrusting their muzzles into the cold water foaming over the rocky bed. When the horses had drunk their fill they moved on down the canyon. Several miles of fast moving brought them to a high wall of red cliffs. Here Crazy River turned east and the canyon deepened. The chestnut sent the band up a trail which switchbacked and looped up out of the depths. With bared teeth and smashing hoofs he shoved the band up the trail and onto a mesa. Out on flat ground he let them rest. He was heading toward the desert where they would be free of attack from armed riders. The mares fed on the bunch grass which carpeted the mesa. They kept well together and jerked up their heads, whinnying to their colts when the little ones strayed. There was danger in each adventurous trip the colts made, for they had not yet learned to watch and to listen. This broken country was the natural home of the cougar. It was also the den area for the gray wolves. When the colts trotted too far, their mothers followed and herded them back.
