What does Huck tell the duke when he sees him the next day?

While Huck is walking walking to the Phelps's farm, he sees the Duke along the way. The Duke is posting advertisements for the Royal Nonesuch, which the two men are planning to perform again. When he sees Huck, the Duke gets extremely nasty and is afraid Huck will warn the townspeople. Next, he lies to Huck and tells him Jim was sold to a farm several days away and threatens Huck in order to keep him silent. Huck promises not to say a word, and hopes he will never have to deal with men such as the Duke and King ever again.
