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:

"Well, Coo-ee-oh used just three magic words, one to make the bridge
work, and one to make the submarines go out of their holes, and one to
raise and lower the island. Three words. And Coo-ee-oh's name is made
up of just three words. 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. 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
