Chapter Twenty. A Puzzling Problem - Page 2

island and halted with its bow pressed against the huge marble door in the basement under the Dome. This door was tightly closed and it was evident to both Glinda and the Wizard that it would not open to admit the underwater boat unless a magic word was spoken by them or someone from within the basement of the island. But what was this magic word? Neither of them knew.

"I'm afraid," said the Wizard regretfully, "that we can't get in, after all. Unless your sorcery can discover the word to open the marble door."

"That is probably some word only known to Coo-ce-oh," replied the Sorceress. "I may be able to discover what it is, but that will require time. Let us go back again to our companions."

"It seems a shame, after we have made the boat obey us, to be balked by just a marble door," grumbled the Wizard.

At Glinda's command the boat rose until it was on a level with the glass dome that covered the Skeezer village, when the Sorceress made it slowly circle all around the Great Dome.

Many faces were pressed against the glass from the inside, eagerly watching the submarine, and in one place were Dorothy and Ozma, who quickly recognized Glinda and the Wizard through the glass windows of the boat. Glinda saw them, too, and held the boat close to the Dome while the friends exchanged greetings in pantomime. Their voices, unfortunately, could not be heard through the Dome and the water and the side of the boat. The Wizard tried to make the girls understand, through signs, that he and Glinda had come to their rescue, and Ozma and Dorothy understood this from the very fact that the Sorceress and the Wizard had appeared. The two girl prisoners were smiling and in safety, and knowing this Glinda felt she could take all the time necessary in order to effect their final rescue.

As nothing more could be done just then, Glinda ordered the boat to return to shore and it obeyed readily. First it ascended to the surface of the water, then the roof parted and fell into the slots at the side of the boat, and then the magic craft quickly made the shore and beached itself on the sands at the very spot from which it had departed at Glinda's command. All the Oz people and the Skeezers at once ran to the boat to ask if they had reached the island, and whether they had seen Ozma and Dorothy. The Wizard told them of the obstacle they had met in the way of a marble door, and how Glinda would now undertake to find a magic way to conquer the door.

Realizing that it would require several days to succeed in reaching the island raising it and liberating their friends and the Skeezer people, Glinda now prepared a camp half way between the lake shore and the palm trees.

The Wizard's wizardry made a number of tents appear and the sorcery of the Sorceress furnished these tents all complete, with beds, chairs, tables, flags, lamps and even books with
