The Magic WordsMany interesting things were to be seen in the Room of Magic, including much that had been stolen from the Adepts when they were transformed to fishes, but they had to admit that Coo-ee-oh had a rare genius for mechanics, and had used her knowledge in inventing a lot of mechanical apparatus that ordinary witches, wizards and sorcerers could not understand.
They all carefully inspected this room, taking care to examine every article they came across.
"The island," said Glinda thoughtfully, "rests on a base of solid marble. When it is submerged, as it is now, the base of the island is upon the bottom of the lake. What puzzles me is how such a great weight can be lifted and suspended in the water, even by magic.""I now remember," returned Aujah, "that one of the arts we taught Coo-ee-oh was the way to expand steel, and I think that explains how the island is raised and lowered. I noticed in the basement a big steel pillar that passed through the floor and extended upward to this palace. Perhaps the end of it is concealed in this very room. If the lower end of the steel pillar is firmly embedded in the bottom of the lake, Coo-ee-oh could utter a magic word that would make the pillar expand, and so lift the entire island to the level of the water.""I've found the end of the steel pillar. It's just here," announced the Wizard, pointing to one side of the room where a great basin of polished steel seemed to have been set upon the floor.
They all gathered around, and Ozma said:
"Yes, I am quite sure that is the upper end of the pillar that supports the island. I noticed it when Ifirst came here. It has been hollowed out, you see, and something has been burned in the basin, for the fire has left its marks. I wondered what was under the great basin and got several of the Skeezers to come up here and try to lift it for me. They were strong men, but could not move it at all.""It seems to me," said Audah the Adept, "that we have discovered the manner in which Coo-ee-oh raised the island. She would burn some sort of magic powder in the basin, utter the magic word, and the pillar would lengthen out and lift the island with it.""What's this?" asked Dorothy, who had been searching around with the others, and now noticed a slight hollow in the wall, near to where the steel basin stood. As she spoke Dorothy pushed her thumb into the hollow and instantly a small drawer popped out from the wall.
The three Adepts, Glinda and the Wizard sprang forward and peered into the drawer. It was half filled with a grayish powder, the tiny grains of which constantly moved as if impelled by some living force.
"It may be some kind of radium," said the Wizard.
"No," replied Glinda, "it is more wonderful than even radium, for I recognize it as a rare mineral powder called Gaulau by the sorcerers. I wonder how Coo-ee-oh discovered it and where she obtained it.""There is no doubt," said Aujah the Adept, "that this is the magic powder Coo-ee-oh burned in the basin. If only we knew the magic word, I am quite sure we could raise the island.""How can we discover the magic word?" asked Ozma, turning to Glinda as she spoke.
"That we must now seriously consider," answered the Sorceress.
So all of them sat down in the Room of Magic and began to think. It was so still that after a while Dorothy grew nervous. The little girl never could keep silent for long, and at the risk of displeasing her magic-working friends she suddenly said:
