Allen had hardly rejoined his two horses at the place where he had left them the night before when Slivers topped the rim of the gulch and rode toward him. "Steve Brandon runs into the post office just after they close the mail bag an' makes such a holler that they opens her up, an' then he insists on droppin' a letter in personal!" Slivers reported. "That there stage will be along pronto!" Jim Allen cried, as he deftly tightened his cinches and swung into the saddle. "I'm comin' with yuh!" Slivers announced. "Not any!" Allen said positively. "Yuh know, kid, we figgered last night that we'd sorta drift down to Texas an' square yuh so yuh could marry that gal of yours. Yuh got to remember that Uncle Sam don't never forget, if yuh monkey with his mail. So yuh ain't goin'!" "You're goin'!" Slivers argued. Allen grinned. "Hell! There ain't nothin' I could do now that would make it worse!" he explained cheerfully. Slivers watched him ride down the slope toward the trail to Black Rock. * * * * * That morning Jack Allen tacked notices about the town. They read: The following men will leave town before sunset. There followed a list of ten names, and the first one was Jim-twin Allen. Those who are still in town after sunset will be held for investigation and later extradited, if wanted elsewhere. Curious crowds collected about the notices, and friends ran to warn those whose names appeared on the list. The men named received the news in grim silence and made no threats, but the roughs who aspired to being bad and had not been mentioned blustered and threatened as to what they would do if the little sheriff from Wyoming had tried to exile them. In a town full of hard men Jack Allen had unerringly selected the ten who were at all times dangerous, who believed in talking with their guns rather than with their mouths. A short time before the stage left that morning, Jack Allen walked into the office of the jail and found Bill Tucker waiting for him. "Yuh sent for me?" Jack Allen asked bluntly. Bill Tucker silently handed Jack a letter. The little officer of the law read it carefully and then eyed Tucker curiously. There was something about the man that he could not place. Tucker should have been elated, and he seemed frightened. "This gent to be relied upon?" Allen asked after a pause. The big town marshal nodded. His face seemed to have grown suddenly flabby. "Well," said Jack thoughtfully, "he says bluntlike that the ores shipped from the Blue Sky Mine didn't all come from out the same hole, so I reckon that means Baldy Kane is mixed up with these here quartz robbers." Bill Tucker licked his dry lips and nodded.
