“People who live upon the land know only those sea creatures which they are able to catch in nets or upon hooks or those which become disabled and are washed ashore,” remarked the Queen as they swam swiftly through the clear water.  “And those who sail in ships see only the creatures who chance to come to the surface.  But in the deep ocean caverns are queer beings that no mortal has ever heard of or beheld, and some of these we are to visit.  We shall also see some sea shrubs and flowering weeds which are sure to delight you with their beauty.”

The sights really began before they had gone very far from the palace, and a school of butterfly fish, having gorgeous colors spattered over their broad wings, was first to delight the strangers.  They swam just as butterflies fly, with a darting, jerky motion, and called a merry “Good morning!” to the mermaids as they passed.

“These butterfly fish are remarkably active,” said the Princess, “and their quick motions protect them from their enemies.  We like to meet them; they are always so gay and good-natured.”

“Why, so am I!” cried a sharp voice just beside them, and they all paused to discover what creature had spoken to them.

“Take care,” said Clia in a low voice.  “It’s an octopus.”

Trot looked eagerly around.  A long, brown arm stretched across their way in front and another just behind them, but that did not worry her.  The octopus himself came slowly sliding up to them and proved to be well worth looking at.  He wore a red coat with brass buttons, and a silk hat was tipped over one ear.  His eyes were somewhat dull and watery, and he had a moustache of long, hair-like “feelers” that curled stiffly at the ends.  When he tried to smile at them, he showed two rows of sharp, white teeth.  In spite of his red coat and yellow-embroidered vest, his standing collar and carefully tied cravat, the legs of the octopus were bare, and Trot noticed he used some of his legs for arms, as in one of them was held a slender cane and in another a handkerchief.

“Well, well!” said the Octopus.  “Are you all dumb?  Or don’t you know enough to be civil when you meet a neighbor?”

“We know how to be civil to our friends,” replied Trot, who did not like the way he spoke.

“Well, are we not friends, then?” asked the Octopus in an airy tone of voice.

“I think not,” said the little girl.  “Octopuses are horrid creatures.”

“OctoPI, if you please; octoPI,” said the monster with a laugh.

“I don’t see any pie that pleases me,” replied Trot, beginning to get angry.

“OctoPUS means one of us; two or more are called octoPI,” remarked the creature, as if correcting her speech.

“I suppose a lot of you would be a whole bakery!” she said scornfully.

“Our name is Latin.  It was given to us by learned scientists years ago,” said the Octopus.”

“That’s true enough,” agreed Cap’n Bill.  “The learned scientists named ev’ry blamed thing they come across, an’ gener’ly they picked out names as nobody could understand or pernounce.”
