As they swam out of Anko's palace and the doll-faced fishes left them, Aquareine asked:  
"Would you rather go back to our mermaid home for a time and rest yourselves or would you prefer to start for Giant's Cave at once?"
 
"I guess we'd better go back home," decided Trot. "To our own home, I mean. We've been away quite a while, and King Anko seemed to think it was best."
 
"Very well," replied the Queen. "Let us turn in this direction, then."
 
"You can say goodbye to Merla for us," continued Trot. "She was very nice to us, an' 'specially to Cap'n Bill."
 
"So she was, mate," agreed the sailor, "an' a prettier lady I never knew, even if she is a mermaid, beggin' your pardon, ma'am."
 
"Are we going anywhere near Zog's castle?" asked the girl.
 
"Our way leads directly past the opening in the dome," said Aquareine.
 
"Then let's stop and see what Sacho and the others are doing," suggested Trot. "They can't be slaves any longer, you know, 'cause they haven't any master. I wonder if they're any happier than they were before?"
 
"They seemed to be pretty happy as it was," remarked Cap'n Bill.
 
"It will do no harm to pay them a brief visit," said Princess Clia. "All danger disappeared from the cavern with the destruction of Zog."
 
"I really ought to say goodbye to Brother Joe," observed the sailor man. "I won't see him again, you know, and I don't want to seem unbrotherly."
 
"Very well," said the Queen, "we will reenter the cavern, for I, too, am anxious to know what will be the fate of the poor slaves of the magician."
 
When they came to the hole in the top of the dome, they dropped through it and swam leisurely down toward the castle. The water was clear and undisturbed and the silver castle looked very quiet and peaceful under the radiant light that still filled the cavern. They met no one at all, and passing around to the front of the building, they reached the broad entrance and passed into the golden hall.
 
Here a strange scene met their eyes. All the slaves of Zog, hundreds in number, were assembled in the room, while standing before the throne formerly occupied by the wicked magician was the boy Sacho, who was just beginning to make a speech to his fellow slaves. "At one time or another," he said, "all of us were born upon the earth and lived in the thin air, but now we are all living as the fishes live, and our home is in the water of the ocean. One by one we have come to this place, having been saved from drowning by Zog, the Magician, and by him given power to exist in comfort under water. The powerful master who made us his slaves has now passed away forever, but we continue to live, and are unable to return to our native land, where we would quickly perish. There is no one but us to inherit Zog's possessions, and so it will be best for us to remain in this fine castle and occupy ourselves as we have done before, in providing for the comforts of the community. Only in labor is happiness to be found, and we may as well labor for ourselves as for others.
 
"But we must have a king. Not an evil, cruel master like Zog, but one who will maintain order and issue laws for the benefit of all. We will govern ourselves most happily by having a ruler, or head, selected from among ourselves by popular vote. Therefore I ask you to d............
