"The funniest adventure you ever heard of," asserted the boy with eager pride. "I sailed in a ship that went to pieces in a storm. All on board were drowned but me, and I came mighty near it, to tell the truth. I went down deep, deep into the sea, and at the bottom was Zog, watching the people drown. I tumbled on his head, and he grabbed and saved me, saying I would make a useful slave. By his magic power he made me able to live under water as the fishes live, and he brought me to this castle and taught me to wait upon him as his other slaves do."
"Isn't it a dreadful, lonely life?" asked Trot.
"No indeed," said Sacho. "We haven't any time to be lonely, and the dreadful things Zog does are very exciting and amusing, I assure you. He keeps us guessing every minute, and that makes the life here interesting. Things were getting a bit slow an hour ago, but now that you are here, I'm in hopes we will all be kept busy and amused for some time."
"Are there many others in the castle besides you and Zog?" asked Aquareine.
"Dozens of us. Perhaps hundreds. I've never counted them," said the boy. "But Zog is the only master; all the rest of us are in the same class, so there is no jealousy among the slaves."
"What is Zog like?" Cap'n Bill questioned.
At this the boy laughed, and the laugh was full of mischief. "If I could tell you what Zog is like, it would take me a year," was the reply. "But I can't tell you. Every one has a different idea of what he's like, and soon you will see him yourselves."
"Are you fond of him?" asked Trot.
"If I said yes, I'd get a good whipping," declared Sacho. "I am commanded to hate Zog, and being a good servant, I try to obey. If anyone dared to like Zog, I am sure he'd be instantly fed to the turtles; so I advise you not to like him."
"Oh, we won't," promised Trot.
