When Dorothy and her friends meet the Wizard again, Toto tips over a screen in a corner of the throne room that reveals the Wizard, who sadly explains he is a humbug—an ordinary old man who, by a hot air balloon, came to Oz long ago from Omaha. He provides the Scarecrow with a head full of bran, pins, and needles ("a lot of bran-new brains"), the Tin Woodman with a silk heart stuffed with sawdust, and the Lion a potion of "courage". Their faith in his power gives these items a focus for their desires. He decides to take Dorothy and Toto home and then go back to Omaha in his balloon. At the send-off, he appoints the Scarecrow to rule in his stead, which he agrees to do after helping Dorothy return to Kansas. Toto chases a kitten in the crowd and Dorothy goes after him, but the ropes holding the balloon break and the Wizard floats away.
