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 sea horses love these weeds and to me they are more interesting than the starfish."
Trot now noticed the sea horses 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 sea horses 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 sea-gulls, 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 on 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 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 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.
"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, too.
"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, and 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 sea 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 creatures 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 the 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 sailorman 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 the 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.
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 one 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 troubles.
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 worrited over our Trot. She's too sweet an' too young to be made an end of in this 'ere fashion."
Clia smiled at the 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 the 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 paused 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 talk and 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 was here 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.
