Both Frank and Juba were very much entertained.

"Did you know Topsy, Juba?" asked Frank.

"No, chile, never knowed Topsy. She must have been a no account young nigga. If she'd lived on our plantation she'd have got flogged for her impudence."

"How did you come here, Juba?" asked Frank.

"One of them officers took me to Chicago. I lived out with a lady, but when she died, after a good many years, I went to a 'telligence office, and there I met your papa. He brought me out here. I didn't at first like livin' down under the ground, but I don't mind it now. Massa Fox treats me well, and I ain't no wish to change."
