"Who's Silly?" inquired Benny, picking up a boulder and hurling it into the center of the stream.

"The King," replied the mer-man without turning 'round.

"Humph!" chuckled the Scarecrow, winking at Trot, "I've known many Kings who acted silly and who looked silly, but I have never met one who called himself that. Do you mean to say you call him Silly right to his face?"

"To his side face," answered the mer-man solemnly. "He only has half a face," he added, stopping again. "That's all anyone has here. That's all you'll have presently," he predicted gloomily.

"Half a face!" gasped Trot, putting one hand to her cheek and looking around uneasily. "Why what do you mean?"

"Are you a Cave man?" demanded the Scarecrow, running around and planting himself in front of the old mer-man. "If you're not, get us out of here. My face may be funny, but I'm attached to it and it's attached to me and nobody can have half of Trot's face either!"

"Nor mine!" panted Benny, bringing his stone heels together with a resounding click. "Show us the way out of here or I'll tread on your tail."

"There is no way out," quavered their guide, sitting down on a sapphire rock and waving his tail about sadly. "I have been here for years, ever since Mombi stole the Queen of the Ozure Isles and sent Quiberon to plague the Islanders."

"Mombi! Why Mombi was put out two years ago," exclaimed Trot, dropping down on another rock. "Do you mean to say she stole this Queen before then? And were those the Ozure Isles we flew over this morning?"

"Were they jeweled islands?" inquired the mer-man eagerly, "and did you see a City of Sapphires?" Trot shook her head quickly and the old mer-man, covering his face with both hands began to rock to and fro with grief. "If I could but see the Sapphire City once more, if I could just see the jeweled rocks and the blue waters of Orizon," he mumbled miserably.
