"No? You said that fellow had no beard."

"I don't believe this man's beard is all right."

Frank was aroused. He fancied that he saw a ray of light.

The fellow who had called himself Professor Colbath turned away. He had heard the hostler whisper, and he caught Frank's question. Immediately he showed a desire to get out.

Leaving the horse to Grody, Frank quickly placed himself before the stranger, saying:

"Hold on a minute. I don't know but I'll talk with you a little."

"No, yer won't!" growled the man. "I'm done tryin' to talk with a fresh youngster like you—I'm done with you."

"Well, I am not done with you!"

Frank's voice rang out sharp and stern.
