The three Adepts assured the excited Flatheads that they had nothing to fear.

Seeing that his people had rebelled the Su-dic ran away and tried to hide, but the Adepts found him and had him cast into a prison, all his cans of brains being taken away from him.

After this easy conquest of the Su-dic, Glinda told the Adepts of her plan, which had already been approved by Ozma of Oz, and they joyfully agreed to it. So, during the next few days, the great Sorceress transformed, in a way, every Flathead on the mountain.

Taking them one at a time, she had the can of brains that belonged to each one opened and the contents spread on the flat head, after which, by means of her arts of sorcery, she caused the head to grow over the brains -- in the manner most people wear them -- and they were thus rendered as intelligent and good looking as any of the other inhabitants of the Land of Oz.

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.
