Rinkitink in Oz by L. Frank Baum

Ozma had seen in her Magic Picture the liberation of Inga's parents and the departure of the entire party for the Emerald City, so with her usual hospitality she ordered a splendid banquet prepared and invited all her quaint friends who were then in the Emerald City to be present that evening to meet the strangers who were to become her guests.

Glinda, also, in her wonderful Record Book had learned of the events that had taken place in the caverns of the Nome King and she became especially interested in the enchantment of the Prince of Boboland. So she hastily prepared several of her most powerful charms and then summoned her flock of sixteen white storks, which swiftly bore her to Ozma's palace. She arrived there before the Red Wagon did and was warmly greeted by the girl Ruler.
