From the books of his ancestors, he learned the following facts:

(1) That Ozma of Oz was the fairy ruler of the Emerald City and the Land of Oz and that she could not be destroyed by any magic ever devised. Also, by means of her Magic Picture she would be able to discover anyone who approached her royal palace with the idea of conquering it.

(2) That Glinda the Good was the most powerful Sorceress in Oz, among her other magical possessions being the Great Book of Records, which told her all that happened anywhere in the world. This Book of Records was very dangerous to Ugu's plans, and Glinda was in the service of Ozma and would use her arts of sorcery to protect the girl Ruler.

(3) That the Wizard of Oz, who lived in Ozma's palace, had been taught much powerful magic by Glinda and had a bag of magic tools with which he might be able to conquer the Shoemaker.

(4) That there existed in Oz--in the Yip Country--a jeweled dishpan made of gold, which dishpan would grow large enough for a man to sit inside it. Then, when he grasped both the golden handles, the dishpan would transport him in an instant to any place he wished to go within the borders of the Land of Oz.
