Of course every eye was at first fixed upon this dome, where Ozma and Dorothy and the Skeezers were still fast prisoners. But soon their attention was caught by a more brilliant sight, for here was the Diamond Swan swimming just before them, its long neck arched proudly, the amethyst eyes gleaming and all the diamond-sprinkled feathers glistening splendidly under the rays of the sun.
"That," said Glinda, "is the transformation of Queen Coo-ce-oh, the haughty and wicked witch who betrayed the three Adepts at Magic and treated her people like slaves."
"She's wonderfully beautiful now," remarked the Frogman.
"It doesn't seem like much of a punishment," said Trot. "The Flathead Su-dic ought to have made her a toad."
"I am sure Coo-ee-oh is punished," said Glinda, "for she has lost all her magic power and her grand palace and can no longer misrule the poor Skeezers."
"Let us call to her, and hear what she has to say," proposed the Wizard.
So Glinda beckoned the Diamond Swan, which swam gracefully to a position near them. Before anyone could speak Coo-ee-oh called to them in a rasping voice -- for the voice of a swan is always harsh and unpleasant -- and said with much pride:
"Admire me, Strangers! Admire the lovely Coo-ee-oh, the handsomest creature in all Oz. Admire me!"
"Handsome is as handsome does," replied the Scarecrow. "Are your deeds lovely, Coo-ce-oh?"
"Deeds? What deeds can a swan do but swim around and give pleasure to all beholders?" said the sparkling bird.
"Have you forgotten your former life? Have you forgotten your magic and witchcraft?" inquired the Wizard.
"Magic -- witchcraft? Pshaw, who cares for such silly things?" retorted Coo-ee-oh. "As for my past life, it seems like an unpleasant dream. I wouldn't go back to it if I could. Don't you admire my beauty, Strangers?"
"Tell us, Coo-ee-oh," said Glinda earnestly, "if you can recall enough of your witchcraft to enable us to raise the sunken island to the surface of the lake. Tell us that and I'll give you a string of pearls to wear around your neck and add to your beauty."
"Nothing can add to my beauty, for I'm the most beautiful creature anywhere in the whole world."
"But how can we raise the island?"
"I don't know and I don't care. If ever I knew I've forgotten, and I'm glad of it," was the response. "Just watch me circle around and see me glitter!
"It's no use," said Button Bright; "the old Swan is too much in love with herself to think of anything else."
"That's a fact," agreed Betsy with a sigh; "but we've got to get Ozma and Dorothy out of that lake, somehow or other."
"And we must do it in our own way," added the Scarecrow.
"But how?" asked Uncle Henry in a grave voice, for he could not bear to think of his dear niece Dorothy being out there under water; "how shall we do it?"
"Leave that to Glinda," advised the Wizard, realizing he was helpless to do it himself.
"If it were just an ordinary sunken island," said the powerful sorceress, "there would be several ways by which I might bring it to the surface again. But this is a Magic Isle, and by some curious art of witchcraft, unknown to any but Queen Coo-ce-oh, it obeys certain commands of magic and will not respond to any other. I do not despair in the least, but it will require some deep study to solve this difficult problem. If the Swan could only remember the witchcraft that she invented and knew as a woman, I could force her to tell me the secret, but all her former knowledge is now forgotten."
"It seems to me," said the Wizard after a brief silence had followed Glinda's speech, "that there are three fishes in this lake that used to be Adepts at Magic and from whom Coo-ee-oh stole much of her knowledge. If we could find those fishes and return them to their former shapes, they could doubtless tell us what to do to bring the sunken island to the surface."
"I have thought of those fishes," replied Glinda, "but among so many fishes as this lake contains how are we to single them out?"
You will understand, of course, that had Glinda been at home in her castle, where the Great Book of Records was, she would have known that Ervic the Skeezer already had taken the gold and silver and bronze fishes from the lake.
