right Sorceress stood Audah and Aurah, while left stood the Wizard and Aujah Together they stretched their arms over the water's edge and in unison the five chanted rhythmic incantation

This chant they repeated again and again, swaying their arms gently from side to side, and the watchers behind them noticed lake had begun to recede shore Before long the highest point dome appeared above the water Gradually the water fell, making the dome appear to rise When three or four feet above the surface Glinda gave the signal to stop, for their work accomplished

The blackened submarine was now entirely out of water, but Uncle Henry and Cap'n Bill managed to push it lake Glinda, the Wizard, Ervic Adepts got boat, taking coil of strong rope, and command Sorceress the craft cleaved its way water toward the part Dome now visible

"There's still plenty of water fish to swim in," observed the Wizard rode along " like more but I'm sure get along until raised the island and can fill up the lake again "

The boat touched gently sloping glass Dome, Wizard took some tools black bag and quickly removed one large pane of glass, thus making hole large enough for their bodies through Stout frames of steel supported the glass Dome, and around frames the Wizard tied the end of rope

"I'll go down first," said he, "for while I'm not as spry as Cap'n Bill I'm sure manage it easily sure the rope is long enough to reach the bottom ? "

" ," replied the Sorceress

So the Wizard let down the rope and climbing opening lowered himself down, hand over hand, clinging rope legs and feet Below streets village were gathered all the Skeezers, men, women and children, and that Ozma and Dorothy, with Lady Aurex, were filled with joy that their friends were at last coming rescue

The Queen's palace, now occupied by Ozma, was directly center Dome, rope was let down the end of it came just in front palace entrance Several Skeezers held fast rope's end to steady it Wizard reached the ground in safety He hugged first Ozma and then Dorothy, while all the Skeezers cheered as loud as

The Wizard now discovered rope was long enough to reach top Dome ground when doubled, so he tied chair to one end rope and called to Glinda to sit chair while he and Skeezers lowered her pavement the Sorceress reached the ground quite comfortably 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 village greatly frightened by their imprisonment under water, but now realized that an attempt was made to rescue them

Glinda, the Wizard Adepts followed Ozma and Dorothy palace, asked Lady Aurex and Ervic to join them After Ozma had told of her adventures in trying war Flatheads Skeezers, and Glinda had told all Rescue Expedition restoration three Adepts help of Ervic, serious consultation was held how the island made to rise

"I've tried every way in my power," said Ozma, "but Coo-ee-oh used very unusual sort of magic which understand She seems prepared her witchcraft that spoken word is necessary to accomplish her designs, and these spoken words are known only to herself "

" method we taught her," declared Aurah the Adept

" do no more, Glinda," continued Ozma, "so try what your sorcery can accomplish "

"First, then," said Glinda, " visit the basement island, which told is underneath the village "

flight of marble stairs led from one of Coo-ee-oh's private rooms down basement, but party arrived all were puzzled by what they saw center of broad, low room, stood mass of great cog- wheels, chains and pulleys, all interlocked and seeming huge machine; but no engine or other motive power to wheels turn

"This, I suppose, means the island is lowered or raised," said Ozma, "but the magic word needed to move the machinery is unknown "

The three Adepts were carefully examining the mass of wheels, and soon the golden-haired one said:

"These wheels control the island at all contrary, one set is used to open the doors little rooms where the submarines are kept, as seen chains and pulleys used Each boat is kept in little room with two doors, one basement room where now other letting lake

"When Coo-ee-oh used the boat she attacked the Flatheads, she first commanded the basement door to open and with her followers she got 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 back again ? " asked the Wizard

"Why the boat would enter the room filled with water and outer door was closed word of command started pump which pumped all the water room Then the boat would open and Coo-ee-oh could enter the basement "

" ," said the Wizard " clever contrivance, but won't work unless one knows the magic words "

"Another part machinery," explained the white-haired Adept, "is used to extend the bridge island mainland The steel bridge is in room much like that boats are kept, and at Coo-ce-oh's command it would reach out, joint by joint, until its far end touched the shore lake The same magic command would bridge return to its former position the bridge used unless the island was surface water "

"But how suppose Coo-ee-oh managed to sink the island, and make it rise again ? " inquired Glinda

This the Adepts yet explain As nothing more learned basement they mounted the steps Queen's private suite again, and Ozma showed them to 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 seen Room of Magic, including much that stolen Adepts were transformed to fishes, but they had to admit that Coo-ee-oh had rare genius for mechanics, and had used her knowledge in inventing lot of mechanical apparatus that ordinary witches, wizards and sorcerers understand

They all carefully inspected this room, taking care to examine every article they came across

"The island," said Glinda thoughtfully, "rests on base of solid marble When submerged, now, the base island is bottom lake What puzzles me is how such great weight lifted and suspended water, even by magic "

"I now remember," returned Aujah, "that arts we taught Coo-ee-oh way to expand steel, and that explains how the island is raised and lowered I noticed basement big steel pillar that passed floor and extended upward palace Perhaps the end of concealed very room lower end steel pillar is firmly embedded bottom lake, Coo-ee-oh could utter magic word pillar expand, and so lift the entire island level water "

"I've found the end steel pillar It's just here," announced the Wizard, pointing to one side room where great basin of polished steel seemed set floor

They all gathered around, and Ozma said:

"Yes, upper end pillar that supports the island I noticed it when I first came here hollowed out, , and something burned basin, fire has left its marks I wondered under the great basin and got several Skeezers up here and try to lift it They were strong men, but move it at all "

"It seems ," said Audah the Adept, "that discovered the manner Coo-ee-oh raised the island burn some sort of magic powder basin, utter the magic word, pillar would lengthen out and lift the island with it "

"What's this ? " asked Dorothy, who searching around others, and now noticed slight hollow wall, near to where the steel basin stood As she spoke Dorothy pushed her thumb hollow and instantly small drawer popped out wall

The three Adepts, Glinda Wizard sprang forward and peered drawer half filled with grayish powder, the tiny grains constantly moved impelled by some living force

"It some kind of radium," said the Wizard

"No," replied Glinda, " more wonderful than even radium, for I recognize it as rare mineral powder called Gaulau sorcerers I wonder how Coo-ee-oh discovered it and where she obtained it "
