In the drawer with the moving gray powder was a tiny golden cup, which they thought was used for measuring. Glinda filled this cup with the powder and carefully poured it into the shallow basin, which was the top of the great steel pillar supporting the island. Then Aurah the Adept lighted a taper and touched it to the powder, which instantly glowed fiery red and tumbled about the basin with astonishing energy. While the grains of powder still glowed red the Sorceress bent over it and said in a voice of command: "Coo!"
They waited motionless to see what would happen. There was a grating noise and a whirl of machinery, but the island did not move a particle.
Dorothy rushed to the window, which overlooked the glass side of the dome.
"The boats!" she exclaimed. "The boats are all loose an' sailing under water."
"We've made a mistake," said the Wizard gloomily.
"But it's one which shows we are on the right track," declared Aujah the Adept. "We know now that Coo-ee-oh used the syllables of her name for the magic words."
"If 'Coo' sends out the boats, it is probable that ee' works the bridge," suggested Ozma. "So the last part of the name may raise the island."
"Let us try that next then," proposed the Wizard.
He scraped the embers of the burned powder out of the basin and Glinda again filled the golden cup from the drawer and placed it on top the steel pillar. Aurah lighted it with her taper and Ozma bent over the basin and murmured the long drawn syllable: "Oh-h-h!"
Instantly the island trembled and with a weird groaning noise it moved upward -- slowly, very slowly, but with a steady motion, while all the company stood by in awed silence. It was a wonderful thing, even to those skilled in the arts of magic, wizardry and sorcery, to realize that a single word could raise that great, heavy island, with its immense glass Dome.
"Why, we're way above the lake now!" exclaimed Dorothy from the window, when at last the island ceased to move.
"That is because we lowered the level of the water," explained Glinda.
They could hear the Skeezers cheering lustily in the streets of the village as they realized that they were saved.
"Come," said Ozma eagerly, "let us go down and join the people."
"Not just yet," returned Glinda, a happy smile upon her lovely face, for she was overjoyed at their success. "First let us extend the bridge to the mainland, where our friends from the Emerald City are waiting."
It didn't take long to put more powder in the basin, light it and utter the syllable "EE!" The result was that a door in the basement opened and the steel bridge moved out, extended itself joint by joint, and finally rested its far end on the shore of the lake just in front of the encampment.
"Now," said Glinda, "we can go up and receive the congratulations of the Skeezers and of our friends of the Rescue Expedition."
Across the water, on the shore of the lake, the Patchwork Girl was waving them a welcome.
Of course all those who had joined Glinda's expedition at once crossed the bridge to the island, where they were warmly welcomed by the Skeezers. Before all the concourse of people Princess Ozma made a speech from a porch of the palace and demanded that they recognize her as their lawful Ruler and promise to obey the laws of the Land of Oz. In return she agreed to protect them from all future harm and declared they would no longer be subjected to cruelty and abuse.
This pleased the Skeezers greatly, and when Ozma told them they might elect a Queen to rule over them, who in turn would be subject to Ozma of Oz, they voted for Lady Aurex, and that same day the ceremony of crowning the new Queen was held and Aurex was installed as mistress of the palace.
For her Prime Minister the Queen selected Ervic, for the three Adepts had told of his good judgment, faithfulness and cleverness, and all the Skeezers approved the appointment.
Glinda, the Wizard and the Adepts stood on the bridge and recited an incantation that quite filled the lake with water again, and the Scarecrow and the Patchwork Girl climbed to the top of the Great Dome and replaced the pane of glass that had been removed to allow Glinda and her followers to enter.
