"Where did they take the prisoner? Are you informed as to that?" asked the captain.

"They took him to El Paso, I believe," replied Professor Zepplin. "I thought you were aware of what had been done."

"I got wind of something of the sort. You see I have been away in another part of the state on a secret mission for the Governor."

"Exactly."

"Did my men say where they were going before they left you this morning?"

"No. As I have said, they left most mysteriously."

"Which direction did they take?"

"We do not know that either. They disappeared utterly."

"Just like Withem," nodded the guest, smiling. "But I'll pick him up some time to-night. I suppose they are on the track of some of the fellows who have been raising trouble around these parts of late."

"Yes, that's what the lieutenant said. They are after what they call the Border Gang. But I have no need to tell you about it. You surely are familiar with the subject."
