"Do watermelons grow in the sea?" asked Trot.
"Of course, that is why they are called watermelons," replied Tom Atto. "I think I shall serve you a water ice, in addition to the rest. Water ice is an appropriate sea food."
"Have some watercress with the salad," said Cap'n Bill.
"I'd thought of that," declared the cook. "Doesn't my bill of fare make your mouths water?"
"Hurry up and get it ready," suggested Trot.
Tom Atto at once bowed and retired, and when they were done, Cap'n Bill said to the queen, "Do you think, ma'am, we can manage to escape from Zog and his castle?"
"I hope we shall find a way," replied Aquareine. "The evil powers of magic which Zog controls may not prove to be as strong as the fairy powers I possess, but of course I cannot be positive until I discover what this wicked magician is able to do."
Princess Clia was looking out of one of the windows. "I think I can see an opening far up in the top of the dome," she said. They all hastened to the windows to look, and although Trot and Cap'n Bill could see nothing but a solid dome above the castle—perhaps because it was so far away from them—the sharp eyes of Aquareine were not to be deceived.
"Yes," she announced, "there is surely an opening in the center of the great dome. A little thought must convince us that such an opening is bound to exist, for otherwise the water confined within the dome would not be fresh or clear."
"Then if we could escape from this castle, we could swim up to the hole in the dome and get free!" exclaimed Trot.
