as soon as they had breakfasted the next morning, glinda and the wizard and the three adepts went down to the shore of the lake and formed a line with their faces toward the submerged island. all the others came to watch them, but stood at a respectful distance in the background.
at the right of the sorceress stood audah and aurah, while at the left stood the wizard and aujah. together they stretched their arms over the water's edge and in unison the five chanted a rhythmic incantation.
this chant they repeated again and again, swaying their arms gently from side to side, and in a few minutes the watchers behind them noticed that the lake had begun to recede from the shore. before long the highest point of the dome appeared above the water. gradually the water fell, making the dome appear to rise. when it was three or four feet above the surface glinda gave the signal to stop, for their work had been accomplished.
the blackened submarine was now entirely out of water, but uncle henry and cap'n bill managed to push it into the lake. glinda, the wizard, ervic and the adepts got into the boat, taking with them a coil of strong rope, and at the command of the sorceress the craft cleaved its way through the water toward the part of the dome which was now visible.
"there's still plenty of water for the fish to swim in," observed the wizard as they rode along. "they might like more but i'm sure they can get along until we have raised the island and can fill up the lake again."
the boat touched gently on the sloping glass of the dome, and the wizard took some tools from his black bag and quickly removed one large pane of glass, thus making a hole large enough for their bodies to pass through. stout frames of steel supported the glass of the dome, and around one of these frames the wizard tied the end of a rope.
"i'll go down first," said he, "for while i'm not as spry as cap'n bill i'm sure i can manage it easily. are you sure the rope is long enough to reach the bottom?"
"quite sure," replied the sorceress.
so the wizard let down the rope and climbing through the opening lowered himself down, hand over hand, clinging to the rope with his legs and feet. below in the streets of the village were gathered all the skeezers, men, women and children, and you may be sure that ozma and dorothy, with lady aurex, were filled with joy that their friends were at last coming to their rescue.
the queen's palace, now occupied by ozma, was directly in the center of the dome, so that when the rope was let down the end of it came just in front of the palace entrance. several skeezers held fast to the rope's end to steady it and the wizard reached the ground in safety. he hugged first ozma and then dorothy, while all the skeezers cheered as loud as they could.
the wizard now discovered that the rope was long enough to reach from the top of the dome to the ground when doubled, so he tied a chair to one end of the rope and called to glinda to sit in the chair while he and some of the skeezers lowered her to the pavement. in this way the sorceress reached the ground quite comfortably and the three adepts and ervic soon followed her.
the skeezers quickly recognized the three adepts at magic, whom they had learned to respect before their wicked queen betrayed them, and welcomed them as friends. all the inhabitants of the village had been greatly frightened by their imprisonment under water, but now realized that an attempt was to be made to rescue them.
glinda, the wizard and the adepts followed ozma and dorothy into the palace, and they asked lady aurex and ervic to join them. after ozma had told of her adventures in trying to prevent war between the flatheads and the skeezers, and glinda had told all about the rescue expedition and the restoration of the three adepts by the help of ervic, a serious consultation was held as to how the island could be made to rise.
"i've tried every way in my power," said ozma, "but coo-ee-oh used a very unusual sort of magic which i do not understand. she seems to have prepared her witchcraft in such a way that a spoken word is necessary to accomplish her designs, and these spoken words are known only to herself."
"that is a method we taught her," declared aurah the adept.
"i can do no more, glinda," continued ozma, "so i wish you would try what your sorcery can accomplish."
"first, then," said glinda, "let us visit the basement of the island, which i am told is underneath the village."
a flight of marble stairs led from one of coo-ee-oh's private rooms down to the basement, but when the party arrived all were puzzled by what they saw. in the center of a broad, low room, stood a mass of great cog-wheels, chains and pulleys, all interlocked and seeming to form a huge machine; but there was no engine or other motive power to make the wheels turn.
"this, i suppose, is the means by which the island is lowered or raised," said ozma, "but the magic word which is needed to move the machinery is unknown to us."
the three adepts were carefully examining the mass of wheels, and soon the golden-haired one said:
"these wheels do not control the island at all. on the contrary, one set of them is used to open the doors of the little rooms where the submarines are kept, as may be seen from the chains and pulleys used. each boat is kept in a little room with two doors, one to the basement room where we are now and the other letting into the lake.
"when coo-ee-oh used the boat in which she attacked the flatheads, she first commanded the basement door to open and with her followers she got into the boat and made the top close over them. then the basement door being closed, the outer door was slowly opened, letting the water fill the room to float the boat, which then left the island, keeping under water."
"but how could she expect to get back again?" asked the wizard.
"why the boat would enter the room filled with water and after the outer door was closed a word of command started a pump which pumped all the water from the room. then the boat would open and coo-ee-oh could enter the basement."
"i see," said the wizard. "it is a clever contrivance, but won't work unless one knows the magic words."
"another part of this machinery," explained the white-haired adept, "is used to extend the bridge from the island to the mainland. the steel bridge is in a room much like that in which the boats are kept, and at coo-ce-oh's command it would reach out, joint by joint, until its far end touched the shore of the lake. the same magic command would make the bridge return to its former position. of course the bridge could not be used unless the island was on the surface of the water."
"but how do you suppose coo-ee-oh managed to sink the island, and make it rise again?" inquired glinda.
this the adepts could not yet explain. as nothing more could be learned from the basement they mounted the steps to the queen's private suite again, and ozma showed them to a special room where coo-ee-oh kept her magical instruments and performed all her arts of witchcraft.
chapter twenty-three
the magic words
many 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 i first 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:
"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 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.
