Here he discovered that he had left too much to his horse. The creature had laid a course to suit himself, carrying him off the trail of those whom he sought in such breathless state. He stopped, looking round him to fix his direction, discovering to his deep vexation that Whetstone had veered from the course that he had laid for him into the south, and was heading toward the river. On again in the right direction, swerving sharply in the hope that he would cut the trail. So for a mile or more, in dusty, headlong race, coming then to the rim of a bowl-like valley and the sound of running shots. Lambert's heart contracted in a paroxysm of fear for the lives of both those flaming combatants as he rode precipitately into the little valley. The shooting had ceased when he came into the clear and pulled up to look for Vesta. The next second the two girls swept into sight. Vesta had not only overtaken her enemy, but had ridden round her and cut off her retreat. She was driving her back toward the spot where Lambert stood, shooting at her as she fled, with what seemed to him a cruel and deliberate hand. CHAPTER XIII "NO HONOR IN HER BLOOD" Vesta was too far behind the other girl for anything like accurate shooting with a pistol, but Lambert feared that a chance shot might hit, with the most melancholy consequences for both parties concerned. No other plan presenting, he rode down with the intention of placing himself between them. Now the Kerr girl had her gun out, and had turned, offering battle. She was still a considerable distance beyond him, with what appeared from his situation to be some three or four hundred yards between the combatants, a safe distance for both of them if they would keep it. But Vesta had no intention of making it a long-range duel. She pulled her horse up and reloaded her gun, then spurred ahead, holding her fire. Lambert saw all this as he swept down between them like an eagle, old Whetstone hardly touching the ground. He cut the line between them not fifty feet from the Kerr girl's position, as Vesta galloped up. He held up his hand in an appeal for peace between them. Vesta charged up to him as he shifted to keep in the line of their fire, coming as if she would ride him down and go on to make an end of that chapter of the long-growing feud. The Kerr girl waited, her pistol hand crossed on the other, with the deliberate coolness of one who had no fear of the outcome. Vesta waved him aside, her face white as ash, and attempted to dash by. He caught her rein and whirled her horse sharply, bringing her face to face with him, her revolver lifted not a yard from his breast. For a moment Lambert read in her eyes an intention that made his heart contract. He held his breath, waiting for the shot. A moment; the film of deadly passion that obscured her eyes like a smoke cleared, the threatening gun faltered, drooped, was lowered. He twisted in his saddle and commanded the Kerr girl with a swing of the arm to go.
