"Then he's in there."

"Yes, came a-running. Was loafing out there in the brush and having a smoke. Said he was going to operate at once, then locked the door."

"Not alone!" Lee exclaimed.

"No, he has help. One of the engineers from the office, who had come trotting over to see what was wrong, and a girl."

"A girl! What girl?"

The foreman shook his head.

"Don't know who she is. She came riding in from the south. When she saw us hustling round, she asked what had happened and jumped off her horse and inquired of the Doc whether she could be of any help. He looked at her, then said yes. She's in there now. One of the men is caring for her horse."

"A bay horse?"

"Yes. And a pretty girl, too. I'd almost lose an arm to have a good-looker like her hovering over me."

"All right, Jenks. You can go back now. Get another man for your crew from Morgan. I'll obtain this fellow's name and his address, if he has any, from the time-keeper, in case he passes in his checks."
