“ The Golden Pig, which ran grunting about the streets, with no brains at all, was disenchanted by Glinda, and in her woman's form was given brains and a round head. This wife of the Su-dic had once been even more wicked than her evil husband, but she had now forgotten all her wickedness and was likely to be a good woman thereafter.
These things being accomplished in a satisfactory manner, Princess Ozma and her people bade farewell to the three Adepts and departed for the Emerald City, well pleased with their interesting adventures. ”

“ As the people from the Emerald City prepared the next morning to depart Queen Aurex said to Ozma:
"There is only one thing I now fear for my people, and that is the enmity of the terrible Su-dic of the Flatheads. He is liable to come here at any time and try to annoy us, and my Skeezers are peaceful folks and unable to fight the wild and wilful Flatheads." ”

“ When all had been treated in this manner there were no more Flatheads at all, and the Adepts decided to name their people Mountaineers. One good result of Glinda's sorcery was that no one could now be deprived of the brains that belonged to him and each person had exactly the share he was entitled to. ”
