One is 'Coo,' and one is 'ee,' and one is 'oh.'" The Wizard frowned but Glinda looked wonderingly at the young girl and Ozma cried out: "A good thought, Dorothy dear! You may have solved our problem." "I believe it is worth a trial," agreed Glinda.

"It would be quite natural for Coo-ee-oh to divide her name into three magic syllables, and Dorothy's suggestion seems like an inspiration." The three Adepts also approved the trial but the brown-haired one said: "We must be careful not to use the wrong word, and send the bridge out under water.

The main thing, if Dorothy's idea is correct, is to hit upon the one word that moves the island." "Let us experiment," suggested the Wizard.
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.
