"'We can follow the creek from Weemer's, and that will throw 'em off the scent,' responded the leader. 'All we'll have to do is to stop the train this side of Blowfen's instead of the other. By the way, keep your ears open for Jamison and the others. We don't want them to go below Blowfen's by mistake.'
"'I'm watching, all right,' said Larson. 'Ain't he got my gun?'
"'Yes, and Lewis promised to bring me some .42 cartridges, too,' said Ricketts. 'Refley sold me a lot of .38's by mistake. When will the express get to Blowfen's?'

"I looked at him and nodded. 'They are going to wreck the express to-night, too,' I added in a whisper.
"'We must stop them.'
"Yes, that was plainly our duty. But how was the deed to be accomplished? We were only two to four, or more, and our small pocket arms would prove of small value should we expose ourselves and provoke a 'mix-up.'
"'That Shorer is the notorious train wrecker from Scotland,' said Rexwell. 'There is a reward up for his capture, I think.'
