er find
out how the mermaids live."

"I don't care how they live, myself," said Cap'n Bill. "I jes' want
'em to let ME live."

"There's no danger," insisted Trot.

"I do' know 'bout that. That's what all the other folks said when
they dove after the mermaids an' got drownded."

"Who?" asked the girl.

"I don't know who, but I've heard tell--"

"You've heard that no one ever saw a mermaid and lived," said Trot.

"To tell the tale," he added, nodding. "An' if we dives down like
they says, we won't live ourselves."

All the mermaids laughed at this, and the brown-haired one said,
"Well, if you are afraid, don't come. You may row your boat out of
this cave and never see us again, if you like. We merely thought it
would please little Mayre, and were willing to show her the sights
of our beautiful home."

"I'd like to see 'em, all right," said Trot, her eyes glistening
with pleasure.

"So would I," admitted Cap'n Bill, "if we would live to tell the
tale."

"Don't you believe us?" asked the mermaid, fixing her lovely eyes on
those of the old sailor and smiling prettily. "Are you afraid to
trust us to bring you safely back?"

"N-n-no," said Cap'n Bill, "'tain't that. I've got to look after
Trot."

"Then you'll have to come with me," said Trot decidedly, "for I'm
going to 'cept this inv'tation. If you don't care to come, Cap'n
Bill, you go home and tell mother I'm visitin' the mermaids."

"She'd scold me inter shivers!" moaned Cap'n Bill with a shudder. "I
guess I'd ruther take my chance down below."

"All right, I'm ready, Miss Mermaid," said Trot. "What shall I do?
Jump in, clothes and all?"

"Give me your hand, dear," answered the mermaid, lifting a lovely
white arm from the water. Trot took the slender hand and found it
warm and soft and not a bit "fishy."

"My name is Clia," continued the mermaid, "and I am a princess in
our deep-sea kingdom."

Just then Trot gave a flop and flopped right out of the boat into
the water. Cap'n Bill caught a gleam of pink scales as his little
friend went overboard, and the next moment there was Trot's face in
the water among those of the mermaids. She was laughing with glee as
she looked up into Cap'n Bill's face and called, "Come on in, Cap'n!
It didn't hurt a bit!"

CHAPTER 3

THE DEPTHS OF THE DEEP BLUE SEA

Cap'n Bill stood up in the boat as if undecided what to do. Never a
sailor man was more bewildered than this old fellow by the
strangeness of th
