"What are you doing here?" asked Captain Pringle, with a smile.
"I want to enlist, sir."
The Captain lifted his eyebrows; perhaps he remembered their last conversation together.
"Will you come this way," he said; "I should like a chat with you."
Bob followed the Captain, while the other fellows looked envyingly towards him.
Captain Pringle led the way to a small room which he evidently used as an office. To all appearance he was in authority at the station.
"I'm rather surprised to see you here, Nancarrow," he said, when he had taken his seat behind a business-looking desk, and pointed Bob to a chair.
"I'm rather surprised myself, sir."
"What have you been doing since I saw you last?"
Bob told him.
