"None at all, your Majesty. Zog is always careful to be well guarded, for he fears the approach of an enemy. What this enemy can be to terrify the great magician I do not know, but Zog is always afraid and never leaves an entrance unguarded. Besides, it is an enchanted castle, you know, and none in the ocean can see it unless Zog wishes him to. So it will be very hard for his enemy to find him."

"We wish to escape," said Clia. "Will you help us, Sacho?"

"In any way I can," replied the boy.

"If we succeed, we will take you with us," continued the Princess.

But Sacho shook his head and laughed. "I would indeed like to see you escape Zog's vengeance," said he, "for vengeance is wrong, and you are too pretty and too good to be destroyed. But I am happy here and have no wish to go away, having no other home or friends other than my fellow slaves."

Then he left them, and when they were again alone, Aquareine said, "We were able to escape Zog's attacks today, but I am quite sure he will plan more powerful ways to destroy us. He has shown that he knows some clever magic, and perhaps I shall not be able to foil it. So it will be well for us to escape tonight if possible."

"Can you fight and conquer the big sea devil up in the dome?" asked Trot.

The queen was thoughtful, and did not reply to this question at once. But Cap'n Bill said uneasily, "I can't abide them devil critters, an' I hopes, for my part, we won't be called on to tackle 'em. You see, Trot, we're in consider'ble of a bad mess, an' if we ever live to tell the tale—"

"Why not, Cap'n?" asked the child. "We're safe enough so far. Can't you trust our good friend, the queen?"

"She don't seem plumb sure o' things herself," remarked the sailor. "The mermaids is all right an' friendly, mate, but this 'ere magic maker, ol' Zog, is a bad one, out 'n' out, an' means to kill us if he can."
