"Sir?"

The "sir" was shouted in a voice of thunder, and the captain's hand moved towards the inner pocket of his coat.

"Un--Uncle Tom, I mean."

"And you better mean it too, and say it, or you'll never say another word. Put your hat on. Catch hold of that Gladstone."

Bertie put his hat on, and took the bag. The captain turned to Mr. Rosenheim.

"Good-bye."

"Good-bye, my friend; I wish you a pleasant journey, and your nephew too."

The captain put his own hat on, took Bertie's hand, led him out of the room, and almost before the lad knew it they were standing in the street. Bertie thanked his stars that at least Mr. Rosenheim was left behind.
