"There's no 'go on' to it," rejoined Jim, revealing equal politeness. "I'm only thinking of a piece I happen to know that runs about a man that's wanted more or less in seven states and two territories. Running double, he's hard to get." Johnson reached over coolly and struck him nastily across the mouth. Then as coolly he sat back, while Jim slowly rose to his feet. His eyes were blazing. "Thanks," he said, tensely. "I've heard a lot about your killings," he went on, breathless with anger. "I guess maybe that's the way--" "Hush!" broke in Glover, excitedly, his eyes upon the ridge to the east. The others turned. Moving slowly along the crest, disappearing, reappearing, disappearing again, was the figure of a man. They gazed a long moment, when the figure dropped from view again. They continued to gaze, silent, rigid, watchful, peering narrowly against the morning sunlight. Presently the figure reappeared, lower against the gray background, moving slowly as before, evidently crouching. Lower it came, quarter down the slope, half-way, then again disappeared. Johnson broke the tense silence. "Sheepherder!" he snapped, and turned savage eyes back upon Jim. But Glover leaped to his feet. "If that's a sheepherder," he cried, making for the horses at a run, "then I'm a sheep!" CHAPTER XVII A RUNNING FIGHT A rifle-shot forced instant action. Jim whirled away from the camp-fire and saddle-bags and sprang toward the horses, while Johnson, leaping up with the agile twist of an athlete, gained his feet running. Jim headed grimly for Pat, but Johnson reached him a breath in advance. Snatching up the reins and mounting, he dug Pat viciously with his huge rowels. At that Pat balked. The man swore and cursed and spurred again; but the horse remained obdurate. Seeing this, Johnson stopped spurring. Thereupon Pat flung forward, dragging his tether clear of its stake, and crowded close beside the gray. Jim was mounted on the gray, bending low in the saddle, racing in frantic pursuit of Glover. Mounted on the sorrel, Glover was well in the lead, speeding straight into the west, riding at right angles to the ridge, galloping hard for the open desert. The echo of the shot reverberated again faintly, and around them closed a tense silence.
