"That’s him," answered Buck. "But he was alone. He ’ll be in soon, ’long with Bill an’ Red—which way did you come?" he demanded eagerly. "Why, that was through his section—bet he saw you an’ pulled out!" Skinny reached for his rifle: "I’m goin’ to see," he remarked. "I ’m with you," replied Buck. "Me, too," asserted Lanky, but he was pushed back. "You stay here," ordered Buck. "He might ride in. An’ you ’ve got to send Bill an’ Red after us." Lanky growled, but obeyed, and trained his rifle on the door. But the only man he saw was Red, whose exit was prompt when he had learned the facts. Down on the south section Bill, unaware of the trend of events, looked over the little pasture that nestled between the hills and wondered where the small herd was. Up to within the last few days he always had found it here, loath to leave the heavy grass and the trickling spring, and watched over by "Old Mosshead," a very pugnacious steer. He scowled as he looked east and shook his head. "Bet they ’re crowdin’ on th’ Weasel’s section, too. Reckon I ’ll go over and look into it. He ’ll be passin’ remarks about th’ way I ride sign." But he reached the river without being rewarded by the sight of many of the missing cows and he became pugnaciously inquisitive. He had searched in vain for awhile when he paused and glanced up the river, catching sight of a horseman who was pushing across at the ford. "Now, what’s th’ Weasel doin’ over there?" he growled. "An’ what’s his hurry? I never did put no trust in him an’ I ’m going to see what’s up." Not far behind him a tall, lean man peered over the grass-fringed bank of a draw and watched him cross the river and disappear over the further bank. "Huh!" muttered Skinny, riding forward toward the river. "That _might_ be one of Peters’ punchers; but I ’ll trail him to make shore." Down the river Red watched Bill cross the stream and then saw a stranger follow. "What th’ h—l!" he growled, pushing on. "That’s one of ’em trailin’ Bill!" and he, in turn, forded the river, hot on the trail of the stranger. Bill finally dismounted near the mesa, proceeded on foot to the top of the nearest rise, and looked down into the canyon at a point where it widened into a circular basin half a mile across. Dust was arising in thin clouds as the missing cows, rounded up by three men, constantly increased the rustlers’ herd. To the northwest lay the mesa, where the canyon narrowed to wind its tortuous way through; to the southeast lay the narrow gateway, where the towering, perpendicular cliffs began to melt into the sloping sides of hills and changed the canyon into a swiftly widening valley. The sight sent the puncher running toward the pass, for the herd had begun to move toward that outlet, urged by the Weasel and his nervous companions.
