"That's nice," said Trot gratefully.

The Princess Clia swam slowly to one of the walls of the throne room where, at a wave of her hand, a round hole appeared in the coral. The sea serpent at once observed this opening and the head left the roof of glass only to reappear presently at the round hole. Through this he slowly crawled until his head was just beneath the throne of Queen Aquareine, who said to him:

"Good morning, your Majesty. I hope you are quite well?"

"Quite well, thank your Majesty," answered Anko; and then he turned to the strangers. "I suppose these are the earth folks you were expecting?"

"Yes," returned the Queen. "The girl is named Mayre and the man Cap'n Bill."

While the sea serpent looked at the visitors, they ventured to look at him. He certainly was a queer creature, yet Trot decided he was not at all frightful. His head was round as a ball, but his ears were sharp-pointed and had tassels at the ends of them. His nose was flat, and his mouth very wide indeed, but his eyes were blue and gentle in expression. The white, stubby hairs that surrounded his face were not thick like a beard, but scattered and scraggly. From the head, the long, brown body of the sea serpent extended to the hole in the coral wall, which was just big enough to admit it; and how much more of the body remained outside the child could not tell. On the back of the body were several fins, which made the creature look more like an eel than a serpent.

"The girl is young and the man is old," said King Anko in a soft voice. "But I'm quite sure Cap'n Bill isn't as old as I am."

"How old are you?" asked the sailor.

"I can't say exactly. I can remember several thousands of years back, but beyond that my memory fails me. How's your memory, Cap'n Bill?"

"You've got me beat," was the reply. "I'll give in that you're older than I am."
