The boat halted and Coo-ee-oh drew back her arm to throw the silver rope toward the Su-dic, who was now but a few feet from her. But the wily Flathead leader quickly realized his danger and before the Queen could throw the rope he caught up one of the copper vessels and dashed its contents full in her face!

Queen Coo-ee-oh dropped the rope, tottered and fell headlong into the water, sinking beneath the surface, while the Skeezers in the submarine assist her and only stared at the ripples in the water where she had disappeared. A moment later there arose to the surface a beautiful White Swan. This Swan was of large size, very gracefully formed, and scattered all over its white feathers were tiny diamonds, so thickly placed that as the rays of the morning sun fell upon them the entire body of the Swan glistened like one brilliant diamond. The head of the Diamond Swan had a bill of polished gold and its eyes were two sparkling amethysts.

"Hooray!" cried the Su-dic, dancing up and down with wicked glee. "My poor wife, Rora, is avenged at last. You made her a Golden Pig, Coo-ee-oh, and now I have made you a Diamond Swan. Float on your lake forever, if you like, for your web feet can do no more magic and you are as powerless as the Pig you made of my wife!"

"Villain! Scoundrel!" croaked the Diamond Swan. "You will be punished for this. Oh, what a fool I was to let you enchant me!"

"A fool you were, and a fool you are!" laughed the Su-dic, dancing madly in his delight. And then he carelessly tipped over the other copper vessel with his heel and its contents spilled on the sands and were lost to the last drop.

The Su-dic stopped short and looked at the overturned vessel with a rueful countenance.

"That's too bad—too bad!" he exclaimed sorrowfully. "I've lost all the poison I had to kill the fishes with, and I can't make any more because only my wife knew the secret of it, and she is now a foolish Pig and has forgotten all her magic."

"Very well," said the Diamond Swan scornfully, as she floated upon the water and swam gracefully here and there. "I'm glad to see you are foiled. Your punishment is just beginning, for although you have enchanted me and taken away my powers of sorcery you have still the three magic fishes to deal with, and they'll destroy you in time, mark my words."

The Su-dic stared at the Swan a moment. Then he yelled to his men:

"Shoot her! Shoot the saucy bird!"

They let fly some arrows at the Diamond Swan, but she dove under the water and the missiles fell harmless. When Coo-ce-oh rose to the surface she was far from the shore and she swiftly swam across the lake to where no arrows or spears could reach her.

The Su-dic rubbed his chin and thought what to do next. Near by floated the submarine in which the Queen had come, but the Skeezers who were in it were puzzled what to do with themselves. Perhaps they were not sorry their cruel mistress had been transformed into a Diamond Swan, but the transformation had left them quite helpless. The under-water boat was not operated by machinery, but by certain mystic words uttered by Coo-ee-oh. They didn't know how to submerge it, or how to make the water-tight shield cover them again, or how to make the boat go back to the castle, or make it enter the little basement room where it was usually kept. As a matter of fact, they were now shut out of their village under the Great Dome and could not get back again. So one of the men called to the Supreme Dictator of the Flatheads, saying:

"Please make us prisoners and take us to your mountain, and feed and keep us, for we have nowhere to go."

Then the Su-dic laughed and answered:

"Not so. I can't be bothered by caring for a lot of stupid Skeezers. Stay where you are, or go wherever you please, so long as you keep away from our mountain." He turned to his men and added: "We have conquered Queen Coo-ee-oh and made her a helpless swan. The Skeezers are under water and may stay there. So, having won the war, let us go home again and make merry and feast, having after many years proved the Flatheads to be greater and more powerful than the Skeezers."

So the Flatheads marched away and passed through the row of palms and went back to their mountain, where the Su-dic and a few of his officers feasted and all the others were forced to wait on them.

"I'm sorry we couldn't have roast pig," said the Su-dic, "but as the only pig we have is made of gold, we can't eat her. Also the Golden Pig happens to be my wife, and even were she not gold I am sure she would be too tough to eat."

When the Flatheads had gone away the Diamond Swan swam back to the boat and one of the young Skeezers named Ervic said to her eagerly:

"How can we get back to the island, your Majesty?"

"Am I not beautiful?" asked Coo-ee-oh, arching her neck gracefully and spreading her diamond-sprinkled wings. "I can see my reflection in the water, and I'm sure there is no bird nor beast, nor human as magnificent as I am!"

"How shall we get back to the island, your Majesty?" pleaded Ervic.

"When my fame spreads throughout the land, people will travel from all parts of this lake to look upon my loveliness," said Coo-ee-oh, shaking her feathers to make the diamonds glitter more brilliantly.

"But, your Majesty, we must go home and we do not know how to get there," Ervic persisted.

"My eyes," remarked the Diamond Swan, "are wonderfully blue and bright and will charm all beholders."

"Tell us how to make the boat go—how to get back into the island," begged Ervic and the others cried just as earnestly: "Tell us, Coo-ee-oh; tell us!"

"I don't know," replied the Queen in a careless tone.

"You are a magic-worker, a sorceress, a witch!"

"I was, of course, when I was a girl," she said, bending her head over the clear water to catch her reflection in it; "but now I've forgotten all such foolish things as magic. Swans are lovelier than girls, especially when they're sprinkled with diamonds. Don't you think so?" And she gracefully swam away, without seeming to care whether they answered or not.

Ervic and his companions were in despair. They saw plainly that Coo-ee-oh could not or would not help them. The former Queen had no further thought for her island, her people, or her wonderful magic; she was only intent on admiring her own beauty.

"Truly," said Ervic, in a gloomy voice, "the Flatheads have conquered us!"

Some of these events had been witnessed by Ozma and Dorothy and Lady Aurex, who had left the house and gone close to the glass of the dome, in order to see what was going on. Many of the Skeezers had also crowded against the dome, wondering what would happen next. Although their vision was to an extent blurred by the water and the necessity of looking upward at an angle, they had observed the main points of the drama enacted above. They saw Queen Coo-ee-oh's submarine come to the surface and open; they saw the Queen standing erect to throw her magic rope; they saw her sudden transformation into a Diamond Swan, and a cry of amazement went up from the Skeezers inside the dome.

"Good!" exclaimed Dorothy. "I hate that old Su-dic, but I'm glad Coo-ee-oh is punished."

"This is a dreadful misfortune!" cried Lady Aurex, pressing her hands upon her heart.

"Yes," agreed Ozma, nodding her head thoughtfully; "Coo-ee-oh's misfortune will prove a terrible blow to her people."
