So the Sorceress now knew that danger threatened her beloved Ruler and Princess Dorothy, and she hurried to her magic room to seek information as to what sort of danger it was. The answer to her question was not very satisfactory, for it was only: "Ozma and Dorothy are prisoners in the great Dome of the Isle of the Skeezers, and the Dome is under the water of the lake."
"Hasn't Ozma the power to raise the island to the surface?" inquired Glinda.
"No," was the reply, and the Record refused to say more except that Queen Coo-ee-oh, who alone could command the island to rise, had been transformed by the Flathead Su-dic into a Diamond Swan.
Then Glinda consulted the past records of the Skeezers in the Great Book. After diligent search she discovered that Coo-ee-oh was a powerful sorceress who had gained most of her power by treacherously transforming the Adepts of Magic, who were visiting her, into three fishes—gold, silver and bronze—after which she had them cast into the lake.
Glinda reflected earnestly on this information and decided that someone must go to Ozma's assistance. While there was no great need of haste, because Ozma and Dorothy could live in a submerged dome a long time, it was evident they could not get out until someone was able to raise the island.
The Sorceress looked through all her recipes and books of sorcery, but could find no magic that would raise a sunken island. Such a thing had never before been required in sorcery. Then Glinda made a little island, covered by a glass dome, and sunk it in a pond near her castle, and experimented in magical ways to bring it to the surface. She made several such experiments, but all were failures. It seemed a simple thing to do, yet she could not do it.
Nevertheless, the wise Sorceress did not despair of finding a way to liberate her friends. Finally she concluded that the best thing to do was to go to the Skeezer country and examine the lake. While there she was more likely to discover a solution to the problem that bothered her, and to work out a plan for the rescue of Ozma and Dorothy.
So Glinda summoned her storks and her aerial chariot, and telling her maids she was going on a journey and might not soon return, she entered the chariot and was carried swiftly to the Emerald City.
In Princess Ozma's palace the Scarecrow was now acting as Ruler of the Land of Oz. There wasn't much for him to do, because all the affairs of state moved so smoothly, but he was there in case anything unforeseen should happen.
Glinda found the Scarecrow playing croquet with Trot and Betsy Bobbin, two little girls who lived at the palace under Ozma's protection and were great friends of Dorothy and much loved by all the Oz people.
