"Yes," said Trot positively.

"Oh, what a disgrace! What a cruel, direful, dreadful disgrace!" moaned the Octopus, drooping his head in shame, and Trot could see great tears falling down his cheeks.

"This comes of having a bad name," said the Queen gently, for she was moved by the monster's grief.

"It is unjust! It is cruel and unjust!" sobbed the creature mournfully. "Just because we have several long arms and take whatever we can reach, they accuse us of being like—like—oh, I cannot say it! It is too shameful, too humiliating."

"Come, let's go," said Trot again. So they left the poor octopus weeping and wiping his watery eyes with his handkerchief and swam on their way. "I'm not a bit sorry for him," remarked the child, "for his legs remind me of serpents."

"So they do me," agreed Cap'n Bill.

"But the octopi are not very bad," said the Princess, "and we get along with them much better than we do with their cousins, the sea devils."

"Oh. Are the sea devils their cousins?" asked Trot.

"Yes, and they are the only creatures of the ocean which we greatly fear," replied Aquareine. "I hope we shall meet none today, for we are going near to the dismal caverns where they live."

"What are the sea devils like, ma'am?" inquired Cap'n Bill a little uneasily.

"Something like the octopus you just saw, only much larger and of a bright scarlet color, striped with black," answered the Queen. "They are very fierce and terrible creatures and nearly as much dreaded by the inhabitants of the ocean as is Zog, and nearly as powerful as King Anko himself."

"Zog! Who is Zog?" questioned the girl. "I haven't heard of him before now."

"We do not like to mention Zog's name," responded the Queen in a low voice. "He is the wicked genius of the sea, and a magician of great power."

"What's he like?" asked Cap'n Bill.

"He is a dreadful creature, part fish, part man, part beast and part serpent. Centuries ago they cast him off the earth into the sea, where he has caused much trouble. Once he waged a terrible war against King Anko, but the sea serpent finally conquered Zog and drove the magician into his castle, where he now stays shut up. For if ever Anko catches the monster outside of his enchanted castle, he will kill him, and Zog knows that very well."

"Seems like you have your troubles down here just as we do on top the ground," remarked Cap'n Bill.

"But I'm glad old Zog is shut up in his castle," added Trot. "Is it a sea castle like your own palace?"

"I cannot say, my dear, for the enchantment makes it invisible to all eyes but those of its inhabitants," replied Aquareine. "No one sees Zog now, and we scarcely ever hear of him, but all the sea people know he is here someplace and fear his power. Even in the old days, before Anko conquered him, Zog was the enemy of the mermaids, as he was of all the good and respectable seafolk. But do not worry about the magician, I beg of you, for he has not dared to do an evil deed in many, many years."

"Oh, I'm not afraid," asserted Trot.

"I'm glad of that," said the Queen. "Keep together, friends, and be careful not to separate, for here comes an army of sawfishes."

Even as Aquareine spoke, they saw a swirl and commotion in the water ahead of them, while a sound like a muffled roar fell upon their ears. Then swiftly there dashed upon them a group of great fishes with long saws sticking out in front of their noses, armed with sharp, hooked teeth, all set in a row. They were larger than the swordfishes and seemed more fierce and bold. But the mermaids and Trot and Cap'n Bill quietly awaited their attack, and instead of tearing them with their saws as they expected to do, the fishes were unable to touch them at all. They tried every possible way to get at their proposed victims, but the Magic Circle was all powerful and turned aside the ugly saws; so our friends were not disturbed at all. Seeing this, the sawfishes soon abandoned the attempt and with growls and roars of disappointment swam away and were quickly out of sight.

Trot had been a wee bit frightened during the attack, but now she laughed gleefully and told the queen that it seemed very nice to be protected by fairy powers. The water grew a darker blue as they descended into its depths, farther and farther away from the rays of the sun. Trot was surprised to find she could see so plainly through the high wall of water above her, but the sun was able to shoot its beams straight down through the transparent sea, and they seemed to penetrate to every nook and crevice of the rocky bottom.

In this deeper part of the ocean some of the fishes had a phosphorescent light of their own, and these could be seen far ahead as if they were lanterns. The explorers met a school of argonauts going up to the surface for a sail, and the child watched these strange creatures with much curiosity. The argonauts live in shells in which they are able to hide in case of danger from prowling wolf fishes, but otherwise they crawl out and carry their shells like humps upon their backs. Then they spread their skinny sails above them and sail away under water till they come to the surface, where they float and let the currents of air carry them along the same as the currents of water had done before. Trot thought the argonauts comical little creatures, with their big eyes and sharp noses, and to her they looked like a fleet of tiny ships.

It is said that men got their first idea of boats and of how to sail them from watching these little argonauts.



CHAPTER 10

THE UNDISCOVERED ISLAND

In following the fleet of argonauts, the four explorers had risen higher in the water and soon found they had wandered to an open space that seemed to Trot like the flat top of a high hill. The sands were covered with a growth of weeds so gorgeously colored that one who had never peered beneath the surface of the sea would scarcely believe they were not the product of a dye shop. Every known hue seemed represented in the delicate, fern-like leaves that swayed softly to and fro as the current moved them. They were not set close together, these branches of magnificent hues, but were scattered sparsely over the sandy bottom of the sea so that while from a distance they seemed thick, a nearer view found them spread out with ample spaces of sand between them.

In these sandy spaces lay the real attractiveness of the place, for here were many of those wonders of the deep that have surprised and interested people in all ages.

First were the starfishes—hundreds of them, it seemed—lying sleepily on the bottom, with their five or six points extended outward. They were of various colors, some rich and brilliant, others of dark brown hues. A few had wound their arms around the weeds or were creeping slowly from one place to another, in the latter case turning their points downward and using them as legs. But most of them were lying motionless, and as Trot looked down upon them she thought they resembled stars in the sky on a bright night, except that the blue of the heavens was here replaced by the white sand, and the twinkling diamond stars by the colored starfish.

"We are near an island," said the Queen, "and that is why so many starfishes are here, as they love to keep close to shore. Also the little seahorses love these weeds, and to me they are more interesting than the starfish."

Trot now noticed the seahorses for the first time. They were quite small—merely two or three inches high—but had funny little heads that were shaped much like the head of a horse, and bright, intelligent eyes. They had no legs, though, for their bodies ended in tails which they twined around the stems of seaweeds to support themselves and keep the currents from carrying them away.

Trot bent down close to examine one of the queer little creatures and exclaimed, "Why, the seahorses haven't any fins or anything to swim with."

"Oh yes we have," replied the Sea Horse in a tiny but distinct voice. "These things on the side of my head are fins."

"I thought they were ears," said the girl.

"So they are. Fins and ears at the same time," answered the little sea animal. "Also, there are small fins on our backs. Of course, we can't swim as the mermaids do, or even as swiftly as fishes; but we manage to get around, thank you."

"Don't the fishes catch and eat you?" inquired Trot curiously.

"Sometimes," admitted the Sea Horse, "and there are many other living things that have a way of destroying us. But here I am, as you see, over six weeks old, and during that time I have escaped every danger. That isn't so bad, is it?"

"Phoo!" said a Starfish lying near. "I'm over three months old. You're a mere baby, Sea Horse."

"I'm not!" cried the Sea Horse excitedly. "I'm full-grown and may live to be as old as you are!"

"Not if I keep on living," said the Starfish calmly, and Trot knew he was correct in his statement.

The little girl now noticed several sea spiders creeping around and drew back because she did not think them very pretty. They were shaped not unlike the starfishes, but had slender legs and big heads with wicked-looking eyes sticking out of them.

"Oh, I don't like those things!" said Trot, coming closer to her companions.

"You don't, eh?" said a big Sea Spider in a cross voice. "Why do you come around here, then, scaring away my dinner when you're not wanted?"

"It isn't YOUR ocean," replied Trot.

"No, and it isn't yours," snapped the Spider. "But as it's big enough for us both, I'd like you to go away."

"So we will," said Aquareine gently, and at once she moved toward the surface of the water. Trot and Cap'n Bill followed, with Clia, and the child asked, "What island are we near?"

"It has no name," answered the Queen, "for it is not inhabited by man, nor has it ever yet been discovered by them. Perhaps you will be the first humans to see this island. But it is a barren, rocky place, and only fit for seals and turtles."

"Are any of them there now?" Cap'n Bill inquired.

"I think so. We will see."

Trot was astonished to find how near they were to the "top" of the ocean, for they had not ascended through the water very long when suddenly her head popped into the air, and she gave a gasp of surprise to find herself looking at the clear sky for the first time since she had started upon this adventure by rowing into Giant's Cave.

She floated comfortably in the water, with her head and face just out of it, and began to look around her. Cap'n Bill was at her side, and so were the two mermaids. The day was fair, and the surface of the sea, which stretched far away as the eye could reach, rippled under a gentle breeze. They had risen almost at the edge of a small, rocky islet, high in the middle, but gradually slanting down to the water. No trees or bushes or grass grew anywhere about; only rocks, gray and bleak, were to be seen.

Trot scarcely noticed this at first, however, for the island seemed covered with groups of forms, some still and some moving, which the old sailor promptly recognized as seals. Many were lying asleep or sunning themselves; others crept awkwardly around, using their strong fins as legs or "paddles" and caring little if they disturbed the slumbers of the others. Once in a while one of those crowded out of place would give a loud and angry bark, which awakened others and set them to barking likewise.

Baby seals were there in great numbers, and were more active and playful than their elders. It was really wonderful how they could scramble around on the land, and Trot laughed more than once at their antics.

At the edge of the water lay many huge turtles, some as big around as a wagon wheel and others much smaller in size.

"The big ones are very old," said the Queen, seeing Trot's eyes fixed on the turtles.

"How old?" asked the child.

"Hundreds of years, I think. They live to a great age, for nothing can harm them when they withdraw their legs and heads into their thick shells. We use some of the turtles for food, but prefer the younger ones. Men also fish for turtles and eat them, but of course no men ever come to this out-of-the-way place in the ocean, so the inhabitants of this little island know they are perfectly safe."

In the center of the island rose high cliffs on top of which were to be seen great flocks of seagulls, some whirling in the air, while others were perched upon the points of rock.

"What do the birds find to eat?" asked Cap'n Bill.

"They often feed upon seals which die of accident or old age, and they are expert fishermen," explained Queen Aquareine. "Curiously enough, the seals also feed upon these birds, which they are often able to catch in their strong jaws when the gulls venture too near. And then, the seals frequently rob the nests of eggs, of which they are very fond."

"I'd like a few gulls' eggs now," remarked a big seal that lay near them upon the shore. Trot had thought him sound asleep, but now he opened his eyes to blink lazily at the group in the water.

"Good morning," said the Queen. "Aren't you Chief Muffruff?"

"I am," answered the old seal. "And you are Aquareine, the mermaid queen. You see, I remember you, although you haven't been here for years. And isn't that Princess Clia? To be sure! But the other mermaids are strangers to me, especially the bald-headed one."

"I'm not a mermaid," asserted Cap'n Bill. "I'm a sailor jes' a-visitin' the mermaids."

"Our friends are earth dwellers," explained the Queen.

"That's odd," said Muffruff. "I can't remember that any earth dwellers ever came this way before. I never travel far, you see, for I'm chief of this disorderly family of seals that live on this island—on it and off it, that is."

"You're a poor chief," said a big turtle lying beside the seal. "If your people are disorderly, it is your own fault."

Muffruff gave a chuckling laugh. Then, with a movement quick as lightning, he pushed his head under the shell of the turtle and gave it a sudden jerk. The huge turtle was tossed up on edge and then turned flat upon its back, where its short legs struggled vainly to right its overturned body.

"There!" snorted the Seal contemptuously. "Perhaps you'll dare insult me again in the presence of visitors, you old mud-wallower!"

Seeing the plight of the turtle, several young seals came laughingly wabbling to the spot, and as they approached the helpless creature drew in his legs and head and closed his two shells tightly together. The seals bumped against the turtle and gave it a push that sent it sliding down the beach like a toboggan, and a minute later it splashed into the water and sank out of sight. But that was just what the creature wanted. On shore the upset turtle was quite helpless; but the mischievous seals saved him. For as soon as he touched the water, he was able to turn and right himself, which he promptly did. Then he raised his head above the water and asked:

"Is it peace or war, Muffruff?"

"Whichever you like," answered the Seal indifferently.

Perhaps the turtle was angry, for it ran on shore with remarkable swiftness, uttering a shrill cry as it advanced. At once all the other turtles awoke to life and with upraised heads joined their comrade in the rush for the seals. Most of Chief Muffruff's band scrambled hastily down the rocks and plunged into the water of the sea without waiting for the turtles to reach them; but the chief himself was slow in escaping. It may be that he was ashamed to run while the mermaids were watching, but if this was so he made a great mistake. The turtles snapped at his fins and tail and began biting round chunks out of them so that Chief Muffruff screamed with pain and anger and floundered into the water as fast as he could go. The vengeful turtles were certainly the victors, and now held undisputed possession of the island.

Trot laughed joyously at the incident, not feeling a bit sorry for the old seal who had foolishly begun the battle. Even the gentle queen smiled as she said:

"These quarrels between the turtles and the seals are very frequent, but they are soon ended. An hour from now they will all be lying asleep together just as we found them; but we will not wait for that. Let us go."

She sank slowly beneath the water again, and the others followed after her.



CHAPTER 11

ZOG THE TERRIBLE AND HIS SEA DEVILS

"The sun must be going under a cloud," said Trot, looking ahead.

They had descended far into the ocean depths again—further, the girl thought, than they had ever been before.

"No," the Queen answered after a glance ahead of them, "that is a cuttlefish, and he is dyeing the sea around him with ink so that he can hide from us. Let us turn a little to the left, for we could see nothing at all in that inky water."

Following her advice, they made a broad curve to the left, and at once the water began to darken in that direction.

"Why, there's another of 'em," said Cap'n Bill as the little party came to a sudden halt.

"So there is," returned the Queen, and Trot thought there was a little quiver of anxiety in her voice. "We must go far to the right to escape the ink."

So they again started, this time almost at a right angle to their former course, the little girl inquired:

"How can the cuttlefish color the water so very black?"

"They carry big sacks in front of them where they conceal the ink," Princess Clia answered. "Whenever they choose, the cuttlefish are able to press out this ink, and it colors the water for a great space around them."

The direction in which they were now swimming was taking them far out of their way. Aquareine did not wish to travel very far to the right, so when she thought they had gone far enough to escape the inky water, she turned to lead her party toward the left—the direction in which she DID wish to go. At once another cloud of ink stained the water and drove them to the right again.

"Is anything wrong, ma'am?" asked Cap'n Bill, seeing a frown gather upon the queen's lovely face.

"I hope not," she said. "But I must warn you that these cuttlefish are the servants of the terrible sea devils, and from the way they are acting they seem determined to drive us toward the Devil Caves, which I wished to avoid."

This admission on the part of their powerful protector, the fairy mermaid, sent a chill to the hearts of the earth people. Neither spoke for a time, but finally Cap'n Bill asked in a timid voice:

"Hadn't we better go back, ma'am?"

"Yes," decided Aquareine after a moment's thought. "I think it will be wise to retreat. The sea devils are evidently aware of our movements and wish to annoy us. For my part, I have no fear of them, but I do not care to have you meet such creatures."

But when they turned around to abandon their journey, another inky cloud was to be seen behind them. They really had no choice but to swim in the only streak of clear water they could find, and the mermaids well knew this would lead them nearer and nearer to the caves of their enemies.

But Aquareine led the way, moving very slowly, and the others followed her. In every other direction they were hemmed in by the black waters, and they did not dare to halt, because the inky fluid crept swiftly up behind them and drove them on.

The queen and the princess had now become silent and grave. They swam on either side of their guests as if to better protect them.

"Don't look up," whispered Clia, pressing close to the little girl's side.

"Why not?" asked Trot, and then she did exactly what she had been told not to do. She lifted her head and saw stretched over them a network of scrawny, crimson arms interlaced like the branches of trees in winter when the leaves have fallen and left them bare.

Cap'n Bill gave a start and muttered "Land sakes!" for he, too, had gazed upward and seen the crimson network of limbs.

"Are these the sea devils?" asked the child, more curious than frightened.

"Yes, dear," replied the Queen. "But I advise you to pay no attention to them. Remember, they cannot touch us."

In order to avoid the threatening arms overhead, which followed them as they swam, our friends kept near to the bottom of the sea, which was here thickly covered with rough and jagged rocks. The inky water had now been left far behind, but when Trot looked over her shoulder, she shuddered to find a great crimson monster following closely after them, with a dozen long, snaky feelers stretched out as if to grab anyone that lagged behind. And there, at the side of Princess Clia, was another devil, leering silently with his cruel, bulging eyes at the pretty mermaid. Beside the queen swam still another of their enemies. Indeed, the sea devils had crept upon them and surrounded them everywhere except at the front, and Trot began to feel nervous and worried for the first time.

Cap'n Bill kept mumbling queer words under his breath, for he had a way of talking to himself when anything "upsot him," as he would quaintly remark. Trot always knew he was disturbed or in trouble when he began to "growl."

The only way now open was straight ahead. They swam slowly, yet fast enough to keep a safe distance from the dreadful creature behind them.

"I'm afraid they are driving us into a trap," whispered the Queen softly. "But whatever happens, do not lose courage, earth friends. Clia and I are here to protect you, and our fairy powers are sufficient to keep you from all harm."

"Oh, I don't mind so very much," declared Trot calmly. "It's like the fairy adventures in storybooks, and I've often thought I'd like that kind of adventures, 'cause the story always turns out the right way."

Cap'n Bill growled something just then, but the only words Trot could make out were, "never lived to tell the tale."

"Oh, pshaw, Cap'n," she said. "We may be in danger, right enough, an' to be honest, I don't like the looks of these sea devils at all. But I'm sure it's no KILLING matter, for we've got the fairy circles all around us."

"Ha ha!" laughed the monster beside her. "WE know all about the fairy circles, don't we, Migg?"

"Ho ho!" laughed the monster on the other side. "We do, Slibb, my boy, and we don't think much of fairy circles, either!"

"They have foiled our enemies many a time," declared the Princess with much dignity.

"Ha ha!" laughed one. "That's why we're here now."

"Ho ho!" laughed the other. "We've learned a trick or two, and we've got you fast this time."

Then all the sea devils—those above and the one behind, and the two on the sides—laughed all together, and their laughter was so horrible that it made even Trot shudder.

But now the queen stopped short, and the others stopped with her.

"I will go no farther," she said firmly, not caring if the monsters overheard her. "It is evident that these monsters are trying to drive us into some secret place, and it is well known that they are in league with Zog the Terrible, whom they serve because they are as wicked as he is. We must be somewhere near the hidden castle of Zog, so I prefer to stay here rather than be driven into some place far more dangerous. As for the sea devils, they are powerless to injure us in any way. Not one of those thousand arms about us can possibly touch our bodies."

The only reply to this defiant speech was another burst of horrible laughter; and now there suddenly appeared before them still another of the monsters, which thus completely hemmed them in. Then the creatures began interlacing their long arms—or "feelers"—until they formed a perfect cage around the prisoners, not an opening being left that was large enough for one of them to escape through.

The mermaids and the girl and sailor man kept huddled close together, for although they might be walled in by the sea devils, their captors could not touch them because of the protecting magic circles.

All at once Trot exclaimed, "Why, we must be moving!"

This was startling news, but by watching the flow of water past them they saw that the little girl was right. The sea devils were swimming, all together, and as the cage they were in moved forward, our friends were carried with it.

Queen Aquareine had a stern look upon her beautiful face. Cap'n Bill guessed from this look that the mermaid was angry, for it seemed much like the look Trot's mother wore when they came home late to dinner. But however angry the queen might be, she was unable to help herself or her guests just now or to escape from the guidance of the dreaded sea devils. The rest of the party had become sober and thoughtful, and in dignified silence they awaited the outcome of this strange adventure.



CHAPTER 12

THE ENCHANTED ISLAND

All at once it grew dark around them. Neither Cap'n Bill nor Trot liked this gloom, for it made them nervous not to be able to see their enemies.

"We must be near a sea cavern, if not within one," whispered Princess Clia, and even as she spoke the network of scarlet arms parted before them, leaving an avenue for them to swim out of the cage. There was brighter water ahead, too, so the queen said without hesitation:

"Come along, dear friends; but let us clasp hands and keep close together."

They obeyed her commands and swam swiftly out of their prison and into the clear water before them, glad to put a distance between themselves and the loathesome sea devils. The monsters made no attempt to follow them, but they burst into a chorus of harsh laughter which warned our friends that they had not yet accomplished their escape.

The four now found themselves in a broad, rocky passage, which was dimly lighted from some unknown source. The walls overhead, below them and at the sides all glistened as if made of silver, and in places were set small statues of birds, beasts and fishes, occupying niches in the walls and seemingly made from the same glistening material.

The queen swam more slowly now that the sea devils had been left behind, and she looked exceedingly grave and thoughtful.

"Have you ever been here before?" asked Trot.

"No, dear," said the Queen with a sigh.

"And do you know where we are?" continued the girl.

"I can guess," replied Aquareine. "There is only one place in all the sea where such a passage as that we are in could exist without my knowledge, and that is in the hidden dominions of Zog. If we are indeed in the power of that fearful magician, we must summon all our courage to resist him, or we are lost!"

"Is Zog more powerful than the mermaids?" asked Trot anxiously.

"I do not know, for we have never before met to measure our strength," answered Aquareine. "But if King Anko could defeat the magician, as he surely did, then I think I shall be able to do so."

"I wish I was sure of it," muttered Cap'n Bill.

Absolute silence reigned in the silver passage. No fish were there; not even a sea flower grew to relieve the stern grandeur of this vast corridor. Trot began to be impressed with the fact that she was a good way from her home and mother, and she wondered if she would ever get back again to the white cottage on the cliff. Here she was, at the bottom of the great ocean, swimming through a big tunnel that had an enchanted castle at the end, and a group of horrible sea devils at the other! In spite of this thought, she was not very much afraid. Although two fairy mermaids were her companions, she relied, strange to say, more upon her tried and true friend, Cap'n Bill, than upon her newer acquaintances to see her safely out of her present trouble.

Cap'n Bill himself did not feel very confident.

"I don't care two cents what becomes o' me," he told Princess Clia in a low voice, "but I'm drea'ful worried over our Trot. She's too sweet an' young to be made an end of in this 'ere fashion."

Clia smiled at this speech. "I'm sure you will find the little girl's end a good way off," she replied. "Trust to our powerful queen, and be sure she will find some means for us all to escape uninjured."

The light grew brighter as they advanced, until finally they perceived a magnificent archway just ahead of them. Aquareine hesitated a moment whether to go on or turn back, but there was no escaping the sea devils behind them, and she decided the best way out of their difficulties was to bravely face the unknown Zog and rely upon her fairy powers to prevent his doing any mischief to herself or her friends. So she led the way, and together they approached the archway and passed through it.

They now found themselves in a vast cavern, so great in extent that the dome overhead looked like the sky when seen from earth. In the center of this immense sea cavern rose the towers of a splendid castle, all built of coral inlaid with silver and having windows of clear glass.

Surrounding the castle were beds of beautiful sea flowers, many being in full bloom, and these were laid out with great care in artistic designs. Goldfish and silverfish darted here and there among the foliage, and the whole scene was so pretty and peaceful that Trot began to doubt there was any danger lurking in such a lovely place.

As they approached to look around them, a brilliantly colored gregfish approached and gazed at them curiously with his big, saucer-like eyes. "So Zog has got you at last!" he said in a pitying tone. "How foolish you were to swim into that part of the sea where he is powerful."

"The sea devils made us," explained Clia.

"Well, I'm sorry for you, I'm sure," remarked the Greg, and with a flash of his tail, he disappeared among the sea foliage.

"Let us go to the castle," said the Queen in a determined voice. "We may as well boldly defy our fate as to wait until Zog seeks us out."

So they swam to the entrance of the castle. The doors stood wide open, and the interior seemed as well lighted as the cavern itself, although none of them could discover from whence the light came.

At each side of the entrance lay a fish such as they had never seen before. It was flat as a doormat and seemed to cling fast to the coral floor. Upon its back were quills like those of a porcupine, all pointed and sharp. From the center of the fish arose a head shaped like a round ball, with a circle of piercing, bead-like eyes set in it. These strange guardians of the entrance might be able to tell what their numerous eyes saw, yet they remained silent and watchful. Even Aquareine gazed upon them curiously, and she gave a little shudder as she did so.

Inside the entrance was a domed hall with a flight of stairs leading to an upper balcony. Around the hall were several doorways hung with curtains made of woven seaweeds. Chairs and benches stood against the wall, and these astonished the visitors because neither stairs nor chairs seemed useful in a kingdom where every living thing was supposed to swim and have a fish's tail. In Queen Aquareine's palaces benches for reclining were used, and stairs were wholly unnecessary, but in the Palace of Zog the furniture and fittings were much like those of a house upon earth, and except that every space here was filled with water instead of air, Trot and Cap'n Bill might have imagined themselves in a handsome earthly castle.

The little group paused half fearfully in the hall, yet so far there was surely nothing to be afraid of. They were wondering what to do next when the curtains of an archway were pushed aside and a boy entered. To Trot's astonishment, he had legs and walked upon them naturally and with perfect ease. He was a delicate, frail-looking little fellow, dressed in a black velvet suit with knee breeches. The bows at his throat and knees were of colored seaweeds, woven into broad ribbons. His hair was yellow and banged across his forehead. His eyes were large and dark, with a pleasant, merry sparkle in them. Around his neck he wore a high ruff, but in spite of this Trot could see that below his plump cheeks were several scarlet-edged slits that looked like the gills of fishes, for they gently opened and closed as the boy breathed in the water by which he was surrounded. These gills did not greatly mar the lad's delicate beauty, and he spread out his arms and bowed low and gracefully in greeting.

"Hello," said Trot.

"Why, I'd like to," replied the boy with a laugh, "but being a mere slave, it isn't proper for me to hello. But it's good to see earth people again, and I'm glad you're here."

"We're not glad," observed the girl. "We're afraid."

"You'll get over that," declared the boy smilingly. "People lose a lot of time being afraid. Once I was myself afraid, but I found it was no fun, so I gave it up."

"Why were we brought here?" inquired Queen Aquareine gently.

"I can't say, madam, being a mere slave," replied the boy. "But you have reminded me of my errand. I am sent to inform you all that Zog the Forsaken, who hates all the world and is hated by all the world, commands your presence in his den."

"Do you hate Zog, too?" asked Trot.

"Oh no," answered the boy. "People lose a lot of time in hating others, and there's no fun in it at all. Zog may be hateful, but I'm not going to waste time hating him. You may do so, if you like."

"You are a queer child," remarked the Mermaid Queen, looking at him attentively. "Will you tell us who you are?"

"Once I was Prince Sacho of Sacharhineolaland, which is a sweet country, but hard to pronounce," he answered. "But in this domain I have but one title and one name, and that is 'Slave.'"

"How came you to be Zog's slave?" asked Clia.

"The funniest adventure you ever heard of," asserted the boy with eager pride. "I sailed in a ship that went to pieces in a storm. All on board were drowned but me, and I came mighty near it, to tell the truth. I went down deep, deep into the sea, and at the bottom was Zog, watching the people drown. I tumbled on his head, and he grabbed and saved me, saying I would make a useful slave. By his magic power he made me able to live under water as the fishes live, and he brought me to this castle and taught me to wait upon him as his other slaves do."

"Isn't it a dreadful, lonely life?" asked Trot.

"No indeed," said Sacho. "We haven't any time to be lonely, and the dreadful things Zog does are very exciting and amusing, I assure you. He keeps us guessing every minute, and that makes the life here interesting. Things were getting a bit slow an hour ago, but now that you are here, I'm in hopes we will all be kept busy and amused for some time."

"Are there many others in the castle besides you and Zog?" asked Aquareine.

"Dozens of us. Perhaps hundreds. I've never counted them," said the boy. "But Zog is the only master; all the rest of us are in the same class, so there is no jealousy among the slaves."

"What is Zog like?" Cap'n Bill questioned.

At this the boy laughed, and the laugh was full of mischief. "If I could tell you what Zog is like, it would take me a year," was the reply. "But I can't tell you. Every one has a different idea of what he's like, and soon you will see him yourselves."

"Are you fond of him?" asked Trot.

"If I said yes, I'd get a good whipping," declared Sacho. "I am commanded to hate Zog, and being a good servant, I try to obey. If anyone dared to like Zog, I am sure he'd be instantly fed to the turtles; so I advise you not to like him."

"Oh, we won't," promised Trot.

"But we're keeping the master waiting, and that is also a dangerous thing to do," continued the boy. "If we don't hurry up, Zog will begin to smile, and when he smiles there is trouble brewing."

The queen sighed. "Lead the way, Sacho," she said. "We will follow."

The boy bowed again, and going to an archway, held aside the curtains for them. They first swam into a small anteroom which led into a long corridor, at the end of which was another curtained arch. Through this Sacho also guided them, and now they found themselves in a cleverly constructed maze. Every few feet were twists and turns and sharp corners, and sometimes the passage would be wide, and again so narrow that they could just squeeze through in single file. "Seems like we're gettin' further into the trap," growled Cap'n Bill. "We couldn't find our way out o' here to save our lives."

"Oh yes we could," replied Clia, who was just behind him. "Such a maze may indeed puzzle you, but the queen or I could lead you safely through it again, I assure you. Zog is not so clever as he thinks himself."

The sailor, however, found the maze very bewildering, and so did Trot. Passages ran in every direction, crossing and recrossing, and it seemed wonderful that the boy Sacho knew just which way to go. But he never hesitated an instant. Trot looked carefully to see if there were any marks to guide him, but every wall was of plain, polished marble, and every turning looked just like all the others. Suddenly Sacho stopped short. They were now in a broader passage, but as they gathered around their conductor they found further advance blocked. Solid walls faced them, and here the corridor seemed to end.

"Enter!" said a clear voice.

"But we can't!" protested Trot.

"Swim straight ahead," whispered the boy in soft tones. "There is no real barrier before you. Your eyes are merely deceived by magic."

"Ah, I understand," said Aquareine, nodding her pretty head. And then she took Mayre's hand and swam boldly forward, while Cap'n Bill followed holding the hand of Clia. And behold! the marble wall melted away before them, and they found themselves in a chamber more splendid than even the fairy mermaids had ever seen before.



CHAPTER 13

PRISONERS OF THE SEA MONSTER

The room in the enchanted castle which Zog called the "den" and in which the wicked sea monster passed most of his time was a perfectly shaped dome of solid gold. The upper part of this dome was thickly set with precious jewels—diamonds, rubies, sapphires and emeralds, which sparkled beautifully through the crystal water. The lower walls were as thickly studded with pearls, all being of perfect shape and color. Many of the pearls were larger than any which may be found upon earth, for the sea people knew where to find the very best and hide them away where men cannot discover them.

The golden floor was engraved with designs of rare beauty, depicting not only sea life, but many adventures upon land. In the room were several large, golden cabinets, the doors of which were closed and locked, and in addition to the cabinets there were tables, chairs and sofas, the latter upholstered with softest sealskins. Handsome rugs of exquisitely woven seaweeds were scattered about, the colors of which were artistically blended together. In one corner a fountain of air bubbled up through the water. The entire room was lighted as brilliantly as if exposed to the direct rays of the sun, yet where this light came from our friends could not imagine. No lamp or other similar device was visible anywhere.

The strangers at first scarcely glanced at all these beautiful things, for in an easy chair sat Zog himself, more wonderful than any other living creature, and as they gazed upon him, their eyes seemed fascinated as if held by a spell. Zog's face was the face of a man, except that the tops of his ears were pointed like horns and he had small horns instead of eyebrows and a horn on the end of his chin. In spite of these deformities, the expression of the face was not unpleasant or repulsive. His hair was carefully parted and brushed, and his mouth and nose were not only perfect in shape but quite handsome.

Only the eyes betrayed Zog and made him terrible to all beholders. They seemed like coals of glowing fire and sparkled so fiercely that no one ever cared to meet their gaze for more than an instant. Perhaps the monster realized this, for he usually drooped his long lashes over his fiery eyes to shut out their glare. Zog had two well-shaped legs which ended in the hoofs of beasts instead of feet, and these hoofs were shod with gold. His body was a shapeless mass covered with richly embroidered raiment, over which a great robe of cloth of gold fell in many folds. This robe was intended to hide the magician's body from view, but Trot noticed that the cloth moved constantly in little ripples, as if what lay underneath would not keep still.

The best features of which Zog could boast were his arms and hands, the latter being as well formed, as delicate and white as those of a well-bred woman. When he spoke, his voice sounded sweet and clear, and its tones were very gentle. He had given them a few moments to stare at him, for he was examining them in turn with considerable curiosity. "Well," said he, "do you not find me the most hateful creature you have ever beheld?"

The queen refrained from answering, but Trot said promptly, "We do. Nothing could be more horrider or more disgustin' than you are, it seems to me."

"Very good, very good indeed," declared the monster, lifting his lashes to flash his glowing eyes upon them. Then he turned toward Cap'n Bill. "Man-fish," he continued, "what do YOU think of me?"

"Mighty little," the sailor replied. "You orter be 'shamed to ask sech a question, knowin' you look worse ner the devil himself."

"Very true," answered Zog, frowning. He felt that he had received a high compliment, and the frown showed he was pleased with Cap'n Bill.

But now Queen Aquareine advanced to a position in front of their captor and said, "Tell me, Zog, why have you trapped us and brought us here?"

"To destroy you," was the quick answer, and the magician turned for an instant to flash his eyes upon the beautiful mermaid. "For two hundred years I have been awaiting a chance to get within my power some friend of Anko the Sea Serpent—of Anko, whom I hate!" he added, smiling sweetly. "When you left your palace today, my swift spies warned me, and so I sent the sea devils to capture you. Often have they tried to do this before, but always failed. Today, acting by my command, they tricked you, and by surrounding you forced you to the entrance of my enchanted castle. The result is a fine capture of important personages. I have now in my power the queen and princess of the fairy mermaids, as well as two wandering earth people, and I assure you I shall take great pleasure in destroying you utterly."

"You are a coward," declared the Queen proudly. "You dared not meet us in the open sea."

"No, I dare not leave this castle," Zog admitted, still smiling. "But here in my own domain my power is supreme. Nothing can interfere with my vengeance."

"That remains to be seen," said Aquareine, firmly meeting the gaze of the terrible eyes.

"Of course," he answered, nodding his head with a graceful movement. "You will try to thwart me and escape. You will pit your fairy power against my powers of magic. That will give me great pleasure, for the more you struggle, the greater will be my revenge."

"But why should you seek revenge upon us?" asked Clia. "We have never harmed you."

"That is true," replied Zog. "I bear you no personal ill will. But you are friends of my great enemy, King Anko, and it will annoy him very much when he finds that you have been destroyed by me. I cannot hurt the rascally old sea serpent himself, but through you I can make him feel my vengeance."

"The mermaids have existed thousands of years," said the Queen in a tone of pride. "Do you imagine the despised and conquered Zog has power to destroy them?"

"I do not know," was the quiet answer. "It will be interesting to discover which is the more powerful."

"I challenge you to begin the test at once, vile magician!" exclaimed Aquareine.

"There is no hurry, fair Queen," answered Zog in his softest tones. "I have been so many years in accomplishing your capture that it is foolish to act hastily now. Besides, I am lonely. Here in my forced retirement I see only those uninteresting earth mortals whom I have made my slaves, for all sea dwellers are forbidden to serve me save the sea devils, and they dare not enter my castle. I have saved many mortals from drowning and brought them here to people my castle, but I do not love mortals. Two lovely mermaids are much more interesting, and before I allow you to perish, I shall have much amusement in witnessing your despair and your struggles to escape. You are now my prisoners. By slow degrees I shall wear out your fairy powers and break your hearts, as well as the hearts of these earth dwellers who have no magic powers, and I think it will be a long time before I finally permit you to die."

"That's all right," said Trot cheerfully. "The longer you take, the better I'll be satisfied."

"That's how I feel about it," added Cap'n Bill. "Don't get in a hurry to kill us Zog. It'll be such a wear an' tear on your nerves. Jes' take it easy an' let us live as long as we can."

"Don't you care to die?" asked the magician.

"It's a thing I never longed for," the sailor replied. "You see, we had no business to go on a trip with the mermaids to begin with. I've allus heard tell that mermaids is dangerous, an' no one as met 'em ever lived to tell the tale. Eh, Trot?"

"That's what you said, Cap'n Bill."

"So I guess we're done for, one way 'r 'nother, an' it don't matter much which. But Trot's a good child, an' mighty young an' tender. It don't seem like her time has come to die. I'd like to have her sent safe home to her mother. So I've got this 'ere proposition to make, Zog. If your magic could make ME die twice, or even THREE times fer good measure, why you go ahead an' do it an' I won't complain. All I ask is fer you to send this little girl safe back to dry land again."

"Don't you do it, Zog!" cried Trot indignantly, and turning to Cap'n Bill, she added, "I'm not goin' to leave you down here in all this mess, Cap'n, and don't you think it. If one of us gets out of the muddle we're in, we'll both get out, so don't you make any bargains with Zog to die twice."

Zog listened to this conversation very carefully. "The dying does not amount to much," he said. "It is the thinking about it that hurts you mortals most. I've watched many a shipwreck at sea, and the people would howl and scream for hours before the ship broke up. Their terror was very enjoyable. But when the end came, they all drowned as peacefully as if they were going to sleep, so it didn't amuse me at all."

"I'm not worrying," said Trot.

"Ner me," said Cap'n Bill. "You'll find we can take what comes jes' as easy as anybody."

"I do not expect to get much from you poor mortals," said Zog carelessly. "You are merely a side show to my circus, a sort of dessert to my feast of vengeance. When the time comes, I can find a hundred ways to kill you. My most interesting prisoners are these pretty mermaids, who claim that none of their race has ever yet died or been destroyed. The first mermaid ever created is living yet, and I am told she is none other than Queen Aquareine. So I have a pretty problem before me to invent some way to destroy the mermaids or put them out of existence. And it will require some thought."

"Also, it will require some power you do not possess," suggested the Queen.

"That may be," replied Zog softly. "But I am going to experiment, and I believe I shall be able to cause you a lot of pain and sorrow before I finally make an end of you. I have not lived twenty-seven thousand years, Aquareine, without getting a certain amount of wisdom, and I am more powerful than you suspect."

"You are a monster and a wicked magician," said the Mermaid Queen.

"I am," agreed Zog, "but I cannot help it. I was created part man, part bird, part fish, part beast and part reptile, and such a monstrosity could not be otherwise than wicked. Everybody hates me, and I hate everybody."

"Why don't you kill yourself?" asked Trot.

"I've tried that and failed," he answered. "Only one being in the world has power to destroy me, and that is King Anko, the sea serpent."

"Then you'd better let him do it," advised the little girl.

"No. Much as I long to die, I cannot allow King Anko the pleasure of killing me. He has always been my worst enemy, and it would be such a joy to him to kill me that I really cannot allow him. Indeed, I have always hoped to kill Anko. I have now been three thousand six hundred and forty-two years, eleven months and nine days figuring out a plan to destroy old Anko, and as yet I have not discovered a way."

"I'd give it up, if I were you," advised Trot. "Don't you think you could get some fun out of trying to be good?"

"No!" cried Zog, and his voice was not so soft as before. "Listen, Aquareine, you and your attendants shall be prisoners in this castle until I can manage to stop you from living. Rooms will be placed at your disposal, and I wish you to go to them at o nce, as I am tired of looking at you."

"You're no more tired than we are," remarked Trot. "It's lucky you can't see yourself, Zog."

He turned his glowing eyes full upon her. "The worst of my queer body I keep concealed," he said. "If ever you see it, you will scream with terror." He touched a bell beside him, and the girl was surprised to find how clearly its tones rang out through the water. In an instant the boy Sacho appeared and bowed low before his dreadful master. "Take the mermaids and the child to the Rose Chamber," commanded Zog, "and take the old man-fish to the Peony Room."

Sacho turned to obey. "Are the outer passages well guarded?" asked the monster.

"Yes, as you have commanded," said the boy.

"Then you may allow the prisoners to roam at will throughout the castle. Now, go!"

The prisoners followed Sacho from the room, glad to get away. The presence of this evil being had grown oppressive to them, and Zog had himself seemed ill at ease during the last few minutes. The robe so closely wound around his body moved jerkily, as if something beneath disturbed it, and at such times Zog shifted nervously in his seat.

Sacho's thin little legs trotted through the water and led the way into a different passage from the one by which they had entered. They swam slowly after him and breathed easier when they had left the golden domed chamber where their wicked enemy sat enthroned. "Well, how do you like him?" asked Sacho with a laugh.

"We hate him!" declared Trot emphatically.

"Of course you do," replied Sacho. "But you're wasting time hating anything. It doesn't do you any good, or him any harm. Can you sing?"

"A little," said Trot, "but I don't feel like singing now."

"You're wrong about that," the boy asserted. "Anything that keeps you from singing is foolishness, unless it's laughter. Laughter, joy and song are the only good things in the world."

Trot did not answer this queer speech, for just then they came to a flight of stairs, and Sacho climbed up them while the others swam. And now they were in a lofty, broad corridor having many doors hung with seaweed draperies. At one of these doorways Sacho stopped and said, "Here is the Rose Chamber where the master commands you to live until you die. You may wander anywhere in the castle as you please; to leave it is impossible. Whenever you return to the Rose Chamber, you will know it by this design of roses sewn in pearls upon the hangings. The Peony Room where the man-fish is to live is the next one farther on."

"Thank you," replied Queen Aquareine. "Are we to be fed?"

"Meals will be served in your rooms. If you desire anything, ring the bell and some of the slaves will be sure to answer it. I am mostly in attendance upon my master, but whenever I am at liberty I will look after your comfort myself."

Again they thanked the strange boy, and he turned and left them. They could hear him whistle and sing as he returned along the passage. Then Princess Clia parted the curtains that her queen and companions might enter the Rose Chamber.



CHAPTER 14

CAP'N JOE AND CAP'N BILL

The rooms Zog had given his prisoners were as handsome as all other parts of this strange enchanted castle. Gold was used plentifully in the decorations, and in the Rose Chamber occupied by the mermaids and Trot golden roses formed a border around the entire room. The sea maidens had evidently been expected, for the magician had provided couches for them to recline upon similar to the ones used in the mermaid palaces. The frames were of mother of pearl and the cushions of soft, white sponges. In the room were toilet tables, mirrors, ornaments and many articles used by earth people, which they afterward learned had been plundered by Zog from sunken ships and brought to his castle by his allies, the sea devils.

While the mermaids were examining and admiring their room, Cap'n Bill went to the Peony Room to see what it was like and found his quarters were very cozy and interesting. There were pictures on the wall, portraits of grave-looking porpoises, bashful seals, and smug and smiling walruses. Some of the wall panels were formed of mirrors and reflected clearly the interior of the room. Around the ceiling was a frieze of imitation peonies in silver, and the furniture was peony-shaped, the broad leaves being bent to form seats and couches. Beside a pretty dressing table hung a bell cord with a tassel at the end. Cap'n Bill did not know it was a bell cord, so he pulled it to see what would happen and was puzzled to find that nothing seemed to happen at all, the bell being too far away for him to hear it. Then he began looking at the treasures contained in this royal apartment, and was much pleased with a golden statue of a mermaid that resembled Princess Clia in feature. A silver flower vase upon a stand contained a bouquet of gorgeous peonies, "as nat'ral as life," said Cap'n Bill, although he saw plainly that they must be made of metal.

Trot came in just then to see how her dear friend was located. She entered from the doorway that connected the two rooms and said, "Isn't it pretty, Cap'n? And who'd ever think that awful creature Zog owned such a splendid castle and kept his prisoners in such lovely rooms?"

"I once heard tell," said the sailor, "of a foreign people that sacrificed humans to please their pagan gods, an' before they killed 'em outright they stuffed the victims full of good things to eat an' dressed 'em in pretty clothes an' treated 'em like princes. That's why I don't take much comfort in our fine surroundin's, Trot. This Zog is a pagan, if ever there was one, an' he don't mean us any good, you may depend on 't."

"No," replied Trot soberly, "I'm sure he does not expect us to be happy here. But I'm going to fool him and have just as good a time as I can." As she spoke they both turned around—an easy thing to do with a single flop of their flexible tails—and Cap'n Bill uttered a cry of surprise. Just across the room stood a perfect duplicate of himself. The round head, with its bald top and scraggly whiskers, the sailor cap and shirt, the wide pantaloons, even the wooden leg, each and every one were exact copies of those owned by Cap'n Bill. Even the expression in the light-blue eyes was the same, and it is no wonder the old sailor stared at his "double" in amazement. But the next minute he laughed and said, "Why, Trot, it's ME reflected in a mirror. But at first I thought it was someone else."

Trot was staring, too. "Look, Cap'n!" she whispered. "Look at the wooden leg."

"Well, it's MY wooden leg, ain't it?" he inquired.

"If it is, it can't be a reflection in a mirror," she argued, "for YOU haven't got a wooden leg. You've got a fish's tail."

The old sailor was so startled by this truth that he gave a great flop with his tail that upset his balance and made him keel a somersault in the water before he got right side up again. Then he found the other sailor man laughing at him and was horrified to find the "reflection" advancing toward them by stumping along on its wooden leg. "Keep away! Get out, there!" yelled Cap'n Bill. "You're a ghost, the ghost o' me that once was, an' I can't bear the sight o' you. Git out!"

"Did you ring jes' to tell me to git out?" asked the other in a mild voice.

"I—I didn't ring," declared Cap'n Bill.

"You did. You pulled that bell cord," said the one-legged (one or more lines missing here in this edition)

"Oh, did pullin' that thing ring a bell?" inquired the Cap'n, a little ashamed of his ignorance and reassured by hearing the "ghost" talk.

"It surely did," was the reply, "and Sacho told me to answer your bell and look after you. So I'm a-lookin' after you."

"I wish you wouldn't," protested Cap'n Bill. "I've no use fer—fer ghostses, anyhow."

The strange sailor began to chuckle at hearing this, and his chuckle was just like Cap'n Bill's chuckle, so full of merry humor that it usually made everyone laugh with him.

"Who are you?" asked Trot, who was very curious and much surprised.

"I'm Cap'n Joe," was the reply. "Cap'n Joe Weedles, formerly o' the brig 'Gladsome' an' now a slave o' Zog at the bottom o' the sea."

"J—J—Joe Wee-Weedles!" gasped Cap'n Bill, amazed. "Joe Weedles o' the 'Gladsome'! Why, dash my eyes, mate, you must be my brother!"

"Are YOU Bill Weedles?" asked the other. And then he added, "But no, you can't be. Bill wasn't no mermaid. He were a human critter like myself."

"That's what I am," said Cap'n Bill hastily. "I'm a human critter, too. I've jes' borrered this fish tail to swim with while I'm visitin' the mermaids."

"Well, well," said Cap'n Joe in astonishment. "Who'd o' thought it! An' who'd ever o' thought as I'd find my long-lost brother in Zog's enchanted castle full fifty fathoms deep down in the wet, wet water!"

"Why, as fer that," replied Cap'n Bill, "it's YOU as is the long-lost brother, not me. You an' your ship disappeared many a year ago, an' ain't never been heard of since, while, as you see, I'm livin' on earth yet."

"You don't look it to all appearances," remarked Cap'n Joe in a reflective tone of voice. "But I'll agree it's many a year since I saw the top o' the water, an' I'm not expectin' to ever tramp on dry land again."

"Are you dead, or drownded, or what?" asked Cap'n Bill.

"Neither one nor t'other," was the answer. "But Zog gave me gills so's I could live in the water like fishes do, an' if I got on land I couldn't breathe air any more'n a fish out o' water can. So I guess as long as I live, I'll hev to stay down here."

"Do you like it?" asked Trot.

"Oh, I don't objec' much," said Cap'n Joe. "There ain't much excitement here, fer we don't catch a flock o' mermaids ev'ry day, but the work is easy an' the rations fair. I might o' been worse off, you know, for when my brig was wrecked, I'd 'a' gone to Davy Jones's Locker if Zog hadn't happened to find me an' made me a fish."

"You don't look as much like a fish as Cap'n Bill does," observed Trot.

"P'raps not," said Cap'n Joe, "but I notice Bill ain't got any gills an' breathes like you an' the mermaids does. When he gets back to land, he'll have his two legs again an' live in comfort breathin' air."

"I won't have two legs," asserted Cap'n Bill, "for when I'm on earth I'm fitted with one wooden leg, jes' the same as you are, Joe."

"Oh, I hadn't heard o' that, Bill, but I'm not surprised," replied Brother Joe. "Many a sailor gets to wear a wooden leg in time. Mine's hick'ry."

"So's mine," said Cap'n Bill with a air of pride. "I'm glad I've run across you, Joe, for I often wondered what had become of you. Seems too bad, though, to have to spend all your life under water."

"What's the odds?" asked Cap'n Joe. "I never could keep away from the water since I was a boy, an' there's more dangers to be met floatin' on it than there is soakin' in it. An' one other thing pleases me when I think on it: I'm parted from my wife, a mighty good woman with a tongue like a two-edge sword, an' my pore widder'll get the insurance money an' live happy. As fer me, Bill, I'm a good deal happier than I was when she kep' scoldin' me from mornin' to night every minute I was home."

"Is Zog a kind master?" asked Trot.

"I can't say he's kind," replied Cap'n Joe, "for he's as near a devil as any livin' critter CAN be. He grumbles an' growls in his soft voice all day, an' hates himself an' everybody else. But I don't see much of him. There's so many of us slaves here that Zog don't pay much attention to us, an' we have a pretty good time when the ol' magician is shut up in his den, as he mostly is."

"Could you help us to escape?" asked the child.

"Why, I don't know how," admitted Cap'n Joe. "There's magic all around us, and we slaves are never allowed to leave this great cave. I'll do what I can, o' course, but Sacho is the boy to help you if anyone can. That little chap knows a heap, I can tell you. So now, if nothin' more's wanted, I must get back to work."

"What work do you do?" Cap'n Bill asked.

"I sew buttons on Zog's clothes. Every time he gets mad, he busts his buttons off, an' I have to sew 'em on again. As he's mad most o' the time, it keeps me busy."

"I'll see you again, won't I, Joe?" said Cap'n Bill.

"No reason why you shouldn't, if you manage to keep alive," said Cap'n Joe. "But you mustn't forget, Bill, this Zog has his grip on you, an' I've never known anything to escape him yet."

Saying this, the old sailor began to stump toward the door, but tripped his foot against his wooden leg and gave a swift dive forward. He would have fallen flat had he not grabbed the drapery at the doorway and saved himself by holding fast to it with both hands. Even then he rolled and twisted so awkwardly before he could get upon his legs that Trot had to laugh outright at his antics. "This hick'ry leg," said Cap'n Joe, "is so blamed light that it always wants to float. Agga-Groo, the goldworker, has promised me a gold leg that will stay down, but he never has time to make it. You're mighty lucky, Bill, to have a merman's tail instead o' legs."

"I guess I am, Joe," replied Cap'n Bill, "for in such a wet country the fishes have the best of it. But I ain't sure I'd like this sort o' thing always."

"Think o' the money you'd make in a side show," said Cap'n Joe with his funny chuckling laugh. Then he pounded his wooden leg against the hard floor and managed to hobble from the room without more accidents.

When he had gone, Trot said, "Aren't you glad to find your brother again, Cap'n Bill?"

"Why, so-so," replied the sailor. "I don't know much about Joe, seein' as we haven't met before for many a long year, an' all I remember about our boyhood days is that we fit an' pulled hair most o' the time. But what worries me most is Joe's lookin' so much like me myself, wooden leg an' all. Don't you think it's rather cheeky an' unbrotherly, Trot?"

"Perhaps he can't help it," suggested the child. "And anyhow, he'll never be able to live on land again."

"No," said Cap'n Bill with a sigh. "Joe's a fish, now, an' so he ain't likely to be took for me by one of our friends on the earth."



CHAPTER 15

THE MAGIC OF THE MERMAIDS

When Trot and Cap'n Bill entered the Rose Chamber they found the two mermaids reclining before an air fountain that was sending thousands of tiny bubbles up through the water.

"These fountains of air are excellent things," remarked Queen Aquareine, "for they keep the water fresh and sweet, and that is the more necessary when it is confined by walls, as it is in this castle. But now, let us counsel together and decide what to do in the emergency that confronts us."

"How can we tell what to do without knowing what's going to happen?" asked Trot.

"Somethin's sure to happen," said Cap'n Bill.

As if to prove his words, a gong suddenly sounded at their door and in walked a fat little man clothed all in white, including a white apron and white cap. His face was round and jolly, and he had a big mustache that curled up at the ends.

"Well, well!" said the little man, spreading out his legs and putting his hands on his hips as he stood looking at them. "Of all the queer things in the sea, you're the queerest! Mermaids, eh?"

"Don't bunch us that way!" protested Cap'n Bill.

"You are quite wrong," said Trot. "I'm a—a girl."

"With a fish's tail?" he asked, laughing at her.

"That's only just for a while," she said, "while I'm in the water, you know. When I'm at home on the land I walk just as you do, an' so does Cap'n Bill."

"But we haven't any gills," remarked the Cap'n, looking closely at the little man's throat, "so I take it we're not as fishy as some others."

"If you mean me, I must admit you are right," said the little man, twisting his mustache. "I'm as near a fish as a man can be. But you see, Cap'n, without the gills that make me a fish, I could not live under water."

"When it comes to that, you've no business to live under water," asserted the sailor. "But I s'pose you're a slave and can't help it."

"I'm chief cook for that old horror Zog. And that reminds me, good mermaids, or good people, or good girls and sailors, or whatever you are, that I'm sent here to ask what you'd like to eat."

"Good to see you, sir," said Cap'n Bill. "I'm nearly starved, myself."

"I had it in mind," said the little man, "to prepare a regular mermaid dinner, but since you're not mermaids—"

"Oh, two of us are," said the Queen, smiling. "I, my good cook, am Aquareine, the ruler of the mermaids, and this is the Princess Clia."

"I've often heard of you, your Majesty," returned the chief cook, bowing respectfully, "and I must say I've heard only good of you. Now that you have unfortunately become my master's prisoners, it will give me pleasure to serve you as well as I am able."

"We thank you, good sir," said Aquareine.

"What have you got to eat?" inquired Trot. "Seems to me I'm hollow way down to my toes—my tail, I mean—and it'll take a lot to fill me up. We haven't eaten a morsel since breakfast, you know."

"I think I shall be able to give you almost anything you would like," said the cook. "Zog is a wonderful magician and can procure anything that exists with no more effort than a wiggle of his thumb. But some eatables, you know, are hard to serve under water, because they get so damp that they are soon ruined."

"Ah, it is different with the mermaids," said Princess Clia.

"Yes, all your things are kept dry because they are surrounded by air. I've heard how the mermaids live. But here it is different."

"Take this ring," said the Queen, handing the chief cook a circlet which she drew from her finger. "While it is in your possession, the food you prepare will not get wet, or even moist."

"I thank your Majesty," returned the cook, taking the ring. "My name is Tom Atto, and I'll do my best to please you. How would you like for luncheon some oysters on the half-shell, clam broth, shrimp salad, broiled turtle steak and watermelon?"

"That will do very nicely," answered the Queen.

"Do watermelons grow in the sea?" asked Trot.

"Of course, that is why they are called watermelons," replied Tom Atto. "I think I shall serve you a water ice, in addition to the rest. Water ice is an appropriate sea food."

"Have some watercress with the salad," said Cap'n Bill.

"I'd thought of that," declared the cook. "Doesn't my bill of fare make your mouths water?"

"Hurry up and get it ready," suggested Trot.

Tom Atto at once bowed and retired, and when they were done, Cap'n Bill said to the queen, "Do you think, ma'am, we can manage to escape from Zog and his castle?"

"I hope we shall find a way," replied Aquareine. "The evil powers of magic which Zog controls may not prove to be as strong as the fairy powers I possess, but of course I cannot be positive until I discover what this wicked magician is able to do."

Princess Clia was looking out of one of the windows. "I think I can see an opening far up in the top of the dome," she said. They all hastened to the windows to look, and although Trot and Cap'n Bill could see nothing but a solid dome above the castle—perhaps because it was so far away from them—the sharp eyes of Aquareine were not to be deceived.

"Yes," she announced, "there is surely an opening in the center of the great dome. A little thought must convince us that such an opening is bound to exist, for otherwise the water confined within the dome would not be fresh or clear."

"Then if we could escape from this castle, we could swim up to the hole in the dome and get free!" exclaimed Trot.

"Why, Zog has probably ordered the opening well guarded, as he has all the other outlets," responded the Queen. "Yet it may be worth while for us to make the attempt to get back into the broad ocean this way. The night would be the best time, when all are asleep, and surely it will be quicker to reach the ocean through this hole in the roof than by means of the long, winding passages by which we entered."

"But we will have to break out of the castle in some way," observed Cap'n Bill.

"That will not be difficult," answered Aquareine. "It will be no trouble for me to shatter one of these panes of glass, allowing us to pass out and swim straight up to the top of the dome."

"Let's do it now!" said Trot eagerly.

"No, my dear, we must wait for a good opportunity when we are not watched closely. We do not wish the terrible Zog to thwart our plan," answered the Queen gently.

Presently two sailor boys entered bearing trays of food, which they placed upon a large table. They were cheery-faced young fellows with gills at their throats, but had laughing eyes, and Trot was astonished not to find any of the slaves of Zog weeping or miserable. Instead, they were as jolly and good-natured as could be and seemed to like their life under the water. Cap'n Bill asked one of the boys how many slaves were in the castle, and the youth replied that he would try to count them and let him know.

Tom Atto had, they found, prepared for them an excellent meal, and they ate heartily because they were really hungry. After luncheon Cap'n Bill smoked his pipe contentedly, and they renewed their conversation, planning various ways to outwit Zog and make their escape. While thus engaged, the gong at the door sounded and Sacho entered.

"My diabolical master commands you to attend him," said the boy.

"When?" asked Aquareine.

"At once, your Majesty."

"Very well, we will follow you," she said. So they swam down the corridors following Sacho until they again reached the golden-domed room they had formerly visited. Here sat Zog just as they had left him, seemingly, but when his prisoners entered, the magician arose and stood upon his cloven feet and then silently walked to a curtained archway.

Sacho commanded the prisoners to follow, and beyond the archway they found a vast chamber that occupied the center of the castle and was as big as a ballroom. Zog, who seemed to walk with much difficulty because his ungainly body swayed back and forth, did not go far beyond the arched entrance. A golden throne was set nearby, and in this the monster seated himself. At one side of the throne stood a group of slaves. They were men, women and children. All had broad gold bands clasped around their ankles as a badge of servitude, and at each throat were the fish's gills that enabled them to breathe and live under water. Yet every face was smiling and serene, even in the presence of their dread master. In parts of the big hall were groups of other slaves.

Sacho ranged the prisoners in a circle before Zog's throne, and slowly the magician turned his eyes, glowing like live coals, upon the four. "Captives," said he, speaking in his clear, sweet voice, "in our first interview you defied me, and both the mermaid queen and the princess declared they could not die. But if that is a true statement, as I have yet to discover, there are various ways to make you miserable and unhappy, and this I propose to do in order to amuse myself at your expense. You have been brought here to undergo the first trial of strength between us." None of the prisoners replied to this speech, so Zog turned to one of his slaves and said, "Rivivi, bring in the Yell-Maker."

Rivivi was a big fellow, brown of skin and with flashing, black eyes. He bowed to his master and left the room by an archway covered with heavy draperies. The next moment these curtains were violently pushed aside, and a dreadful sea creature swam into the hall. It had a body much like that of a crab, only more round and of a jet-black color. Its eyes were bright yellow balls set on the ends of two horns that stuck out of its head. They were cruel-looking eyes, too, and seemed able to see every person in the room at the same time. The legs of the Yell-Maker, however, were the most curious part of the creature. There were six of them, slender and black as coal, and each extended twelve to fifteen feet from its body when stretched out in a straight line. They were hinged in several places so they could be folded up or extended at will. At the ends of these thin legs were immense claws shaped like those of a lobster, and they were real "nippers" of a most dangerous sort.

The prisoners knew, as soon as they saw the awful claws, why the thing was called the "Yell-Maker," and Trot gave a little shiver and crept closer to Cap'n Bill. Zog looked with approval upon the creature he had summoned and said to it, "I give you four victims, the four people with fish's tails. Let me hear how loud they can yell."

The Yell-Maker uttered a grunt of pleasure and in a flash stretched out one of its long legs toward the queen's nose, where its powerful claws came together with a loud noise. Aquareine did not stir; she only smiled. Both Zog and the creature that had attacked her seemed much surprised to find she was unhurt. "Again!" cried Zog, and again the Yell-Maker's claw shot out and tried to pinch the queen's pretty ear. But the magic of the fairy mermaid was proof against this sea-rascal's strength and swiftness, nor could he touch any part of Aquareine, although he tried again and again, roaring with anger like a mad bull.

Trot began to enjoy this performance, and as her merry, childish laughter rang out, the Yell-Maker turned furiously upon the little girl, two of the dreadful claws trying to nip her at the same time. She had no chance to cry out or jump backward, yet she remained unharmed. For the Fairy Circle of Queen Aquareine kept her safe. Now Cap'n Bill was attacked, and Princess Clia as well. The half-dozen slender legs darted in every direction like sword thrusts to reach their victims, and the cruel claws snapped so rapidly that the sound was like the rattling of castanets. But the four prisoners regarded their enemy with smiling composure, and no yell greeted the Yell-Maker's efforts.

"Enough!" said Zog, softly and sweetly. "You may retire, my poor Yell-Maker, for with these people you are powerless."

The creature paused and rolled its yellow eyes. "May I nip just one of the slaves, oh Zog?" it asked pleadingly. "I hate to leave without pleasing your ears with a single yell."

"Let my slaves alone," was Zog's answer. "They are here to serve me and must not be injured. Go, feeble one."

"Not so!" cried the Queen. "It is a shame, Zog, that such an evil thing should exist in our fair sea." With this, she drew her fairy wand from a fold of her gown and waved it toward the creature. At once the Yell-Maker sank down unconscious upon the floor; its legs fell apart in many pieces, the claws tumbling in a heap beside the body. Then all grew withered and lost shape, becoming a pulpy mass, like gelatin. A few moments later the creature had melted away to nothing at all, forever disappearing from the ocean where it had caused so much horror and pain.

Zog watched this destruction with surprising patience. When it was all over, he nodded his head and smiled, and Trot noticed that whenever Zog smiled, his slaves lost their jolly looks and began to tremble. "That is very pretty magic, Aquareine," said the monster. "I myself learned the trick several thousand years ago, so it does not astonish me. Have you fairies nothing that is new to show me?"

"We desire only to protect ourselves," replied the Queen with dignity.

"Then I will give you a chance to do so," said Zog. As he spoke, the great marble blocks in the ceiling of the room directly over the heads of the captives gave way and came crashing down upon them. Many tons of weight were in these marble blocks, and the magician had planned to crush his victims where they stood. But the four were still unharmed. The marble, being unable to touch them, was diverted from its course, and when the roar of the great crash had died away, Zog saw his intended victims standing quietly in their places and smiling scornfully at his weak attempts to destroy them.



CHAPTER 16

THE TOP OF THE GREAT DOME

Cap'n Bill's heart was beating pretty vast, but he did not let Zog know that. Trot was so sure of the protection of the fairy mermaids that she would not allow herself to become frightened. Aquareine and Clia were as calm as if nothing had happened.

"Please excuse this little interruption," said Zog. "I knew very well the marble blocks would not hurt you. But the play is over for a time. You may now retire to your rooms, and when I again invite you to my presence, I shall have found some better ways to entertain you."

Without reply to this threat, they turned and followed Sacho from the hall, and the boy led them straight back to their own rooms.

"Zog is making a great mistake," said Sacho with a laugh. "He has no time for vengeance, but the great magician does not know that."

"What is he trying to do, anyway?" asked Trot.

"He does not tell me all his secrets, but I've an idea he wants to kill you," replied Sacho. "How absurd it is to be plotting such a thing when he might spend his time in laughing and being jolly! Isn't it, now?"

"Zog is a wicked, wicked creature!" exclaimed Trot.

"But he had his good points," replied Sacho cheerfully. "There is no one about in the world so bad that there is nothing good about him."

"I'm not so sure of that," said Cap'n Bill. "What are Zog's good points?"

"All his slaves were saved from drowning, and he is kind to them," said Sacho.

"That is merely the kindness of selfishness," said Aquareine. "Tell me, my lad, is the opening in the great dome outside guarded?"

"Yes indeed," was the reply. "You cannot hope to escape in that way, for the prince of the sea devils, who is the largest and fiercest of his race, lies crouched over the opening night and day, and none can pass his network of curling legs."

"Is there no avenue that is not guarded?" continued Aquareine.

"None at all, your Majesty. Zog is always careful to be well guarded, for he fears the approach of an enemy. What this enemy can be to terrify the great magician I do not know, but Zog is always afraid and never leaves an entrance unguarded. Besides, it is an enchanted castle, you know, and none in the ocean can see it unless Zog wishes him to. So it will be very hard for his enemy to find him."

"We wish to escape," said Clia. "Will you help us, Sacho?"

"In any way I can," replied the boy.

"If we succeed, we will take you with us," continued the Princess.

But Sacho shook his head and laughed. "I would indeed like to see you escape Zog's vengeance," said he, "for vengeance is wrong, and you are too pretty and too good to be destroyed. But I am happy here and have no wish to go away, having no other home or friends other than my fellow slaves."

Then he left them, and when they were again alone, Aquareine said, "We were able to escape Zog's attacks today, but I am quite sure he will plan more powerful ways to destroy us. He has shown that he knows some clever magic, and perhaps I shall not be able to foil it. So it will be well for us to escape tonight if possible."

"Can you fight and conquer the big sea devil up in the dome?" asked Trot.

The queen was thoughtful, and did not reply to this question at once. But Cap'n Bill said uneasily, "I can't abide them devil critters, an' I hopes, for my part, we won't be called on to tackle 'em. You see, Trot, we're in consider'ble of a bad mess, an' if we ever live to tell the tale—"

"Why not, Cap'n?" asked the child. "We're safe enough so far. Can't you trust our good friend, the queen?"

"She don't seem plumb sure o' things herself," remarked the sailor. "The mermaids is all right an' friendly, mate, but this 'ere magic maker, ol' Zog, is a bad one, out 'n' out, an' means to kill us if he can."

"But he can't!" cried Trot bravely.

"I hope you're right, dear. I wouldn't want to bet on Zog's chances jes' yet, an' at the same time it would be riskin' money to bet on our chances. Seems to me it's a case of luck which wins."

"Don't worry, friend," said the Queen. "I have a plan to save us. Let us wait patiently until nightfall." They waited in the Rose Chamber a long time, talking earnestly together, but the brilliant light that flooded both the room and the great dome outside did not fade in the least. After several hours had passed away, the gong sounded and Tom Atto again appeared, followed by four slaves bearing many golden dishes upon silver trays. The friendly cook had prepared a fine dinner, and they were all glad to find that, whatever Zog intended to do to them, he had no intention of starving them. Perhaps the magician realized that Aquareine's fairy powers, if put to the test, would be able to provide food for her companions, but whatever his object may have been, their enemy had given them splendid rooms and plenty to eat.

"Isn't it nearly nighttime?" asked the Queen as Tom Atto spread the table with a cloth of woven seaweed and directed his men to place the dishes upon it.

"Night!" he exclaimed as if surprised. "There is no night here."

"Doesn't it ever get dark?" inquired Trot.

"Never. We know nothing of the passage of time or of day or night. The light always shines just as you see it now, and we sleep whenever we are tired and rise again as soon as we are rested."

"What causes the light?" Princess Clia asked.

"It's magic, your Highness," said the cook solemnly. "It's one of the curious things Zog is able to do. But you must remember all this place is a big cave in which the castle stands, so the light is never seen by anyone except those who live here."

"But why does Zog keep his light going all the time?" asked the Queen.

"I suppose it is because he himself never sleeps," replied Tom Atto. "They say the master hasn't slept for hundreds of years, not since Anko, the sea serpent, defeated him and drove him into this place."

They asked no more questions and began to eat their dinner in silence. Before long, Cap'n Joe came in to visit his brother and took a seat at the table with the prisoners. He proved a jolly fellow, and when he and Cap'n Bill talked about their boyhood days, the stories were so funny that everybody laughed and for a time forgot their worries.

When dinner was over, however, and Cap'n Joe had gone back to his work of sewing on buttons and the servants had carried away the dishes, the prisoners remembered their troubles and the fate that awaited them. "I am much disappointed," said the Queen, "to find there is no night here and that Zog never sleeps. It will make our escape more difficult. Yet we must make the attempt, and as we are tired and a great struggle is before us, it will be best for us to sleep and refresh ourselves."

They agreed to this, for the day had been long and adventurous, so Cap'n Bill kissed Trot and went in to the Peony Room, where he lay down upon his spongy couch and fell fast asleep. The mermaids and Trot followed this example, and I think none of them was much worried, after all, because they quickly sank into peaceful slumber and forgot all the dangers that threatened them.



CHAPTER 17

THE QUEEN'S GOLDEN SWORD

"Goodness me!" exclaimed Trot, raising herself by a flirt of her pink-scaled tail and a wave of her fins, "isn't it dreadful hot here?"

The mermaids had risen at the same time, and Cap'n Bill came swimming in from the Peony Room in time to hear the little girl's speech.

"Hot!" echoed the sailor. "Why, I feel like the inside of a steam engine!"

The perspiration was rolling down his round, red face, and he took out his handkerchief and carefully wiped it away, waving his fish tail gently at the same time.

"What we need most in this room," said he, "is a fan."

"What's the trouble, do you s'pose?" inquired Trot.

"It is another trick of the monster Zog," answered the Queen calmly. "He has made the water in our rooms boiling hot, and if it could touch us, we would be well cooked by this time. Even as it is, we are all made uncomfortable by breathing the heated air."

"What shall we do, ma'am?" the sailor man asked with a groan. "I expected to get into hot water afore we've done with this foolishness, but I don't like the feel o' bein' parboiled, jes' the same."

The queen was waving her fairy wand and paid no attention to Cap'n Bill's moans. Already the water felt cooler, and they began to breathe more easily. In a few moments more, the heat had passed from the surrounding water altogether, and all danger from this source was over.

"This is better," said Trot gratefully.

"Do you care to sleep again?" asked the Queen.

"No, I'm wide awake now," answered the child.

"I'm afraid if I goes to sleep ag'in, I'll wake up a pot roast," said Cap'n Bill.

"Let us consider ways to escape," suggested Clia. "It seems useless for us to remain here quietly until Zog discovers a way to destroy us."

"But we must not blunder," added Aquareine cautiously. "To fail in our attempt would be to acknowledge Zog's superior power, so we must think well upon our plan before we begin to carry it out. What do you advise, sir?" she asked, turning to Cap'n Bill.

"My opinion, ma'am, is that the only way for us to escape is to get out o' here," was the sailor's vague answer. "How to do it is your business, seein' as I ain't no fairy myself, either in looks or in eddication."

The queen smiled and said to Trot, "What is your opinion, my dear?"

"I think we might swim out the same way we came in," answered the child. "If we could get Sacho to lead us back through the maze, we would follow that long tunnel to the open ocean, and—"

"And there would be the sea devils waitin' for us," added Cap'n Bill with a shake of his bald head. "They'd drive us back inter the tunnel like they did the first time, Trot. It won't do, mate, it won't do."

"Have you a suggestion, Clia?" inquired the Queen.

"I have thought of an undertaking," replied the pretty princess, "but it is a bold plan, your Majesty, and you may not care to risk it."

"Let us hear it, anyway," said Aquareine encouragingly.

"It is to destroy Zog himself and put him out of the world forever. Then we would be free to go home whenever we pleased."

"Can you suggest a way to destroy Zog?" asked Aquareine.

"No, your Majesty," Clia answered. "I must leave the way for you to determine."

"In the old days," said the Queen thoughtfully, "the mighty King Anko could not destroy this monster. He succeeded in defeating Zog and drove him into this great cavern, but even Anko could not destroy him."

"I have heard the sea serpent explain that it was because he could not reach the magician," returned Clia. "If King Anko could have seized Zog in his coils, he would have made an end of the wicked monster quickly. Zog knows this, and that is why he does not venture forth from his retreat. Anko is the enemy he constantly dreads. But with you, my queen, the case is different. You may easily reach Zog, and the only question is whether your power is sufficient to destroy him."

For a while Aquareine remained silent. "I am not sure of my power over him," she said at last, "and for that reason I hesitate to attack him personally. His slaves and his allies, the sea devils, I can easily conquer, so I prefer to find a way to overcome the guards at the entrances rather than to encounter their terrible master. But even the guards have been given strength and power by the magician, as we have already discovered, so I must procure a weapon with which to fight them."

"A weapon, ma'am?" said Cap'n Bill, and then he took a jackknife from his coat pocket and opened the big blade, afterward handing it to the queen. "That ain't a bad weapon," he announced.

"But it is useless in this case," she replied, smiling at the old sailor's earnestness. "For my purpose I must have a golden sword."

"Well, there's plenty of gold around this castle," said Trot, looking around her. "Even in this room there's enough to make a hundred golden swords."

"But we can't melt or forge gold under water, mate," the Cap'n said.

"Why not? Don't you s'pose all these gold roses and things were made under water?" asked the little girl.
