The duke says:

"Have you seen anybody else go in there?"

"No, your grace, not as I remember, I believe."

"Stop and think."

I studied awhile and see my chance; then I says:

"Well, I see the niggers go in there several times."

Both of them gave a little jump, and looked like they hadn't ever expected it, and then like they HAD. Then the duke says:

"What, all of them?"

"No—leastways, not all at once—that is, I don't think I ever see them all come OUT at once but just one time."

"Hello! When was that?"
