Sacho's thin little legs trotted through the water and led the way into a different passage from the one by which they had entered. They swam slowly after him and breathed easier when they had left the golden domed chamber where their wicked enemy sat enthroned. "Well, how do you like him?" asked Sacho with a laugh.

"We hate him!" declared Trot emphatically.

"Of course you do," replied Sacho. "But you're wasting time hating anything. It doesn't do you any good, or him any harm. Can you sing?"

"A little," said Trot, "but I don't feel like singing now."

"You're wrong about that," the boy asserted. "Anything that keeps you from singing is foolishness, unless it's laughter. Laughter, joy and song are the only good things in the world."

Trot did not answer this queer speech, for just then they came to a flight of stairs, and Sacho climbed up them while the others swam. And now they were in a lofty, broad corridor having many doors hung with seaweed draperies. At one of these doorways Sacho stopped and said, "Here is the Rose Chamber where the master commands you to live until you die. You may wander anywhere in the castle as you please; to leave it is impossible. Whenever you return to the Rose Chamber, you will know it by this design of roses sewn in pearls upon the hangings. The Peony Room where the man-fish is to live is the next one farther on."

"Thank you," replied Queen Aquareine. "Are we to be fed?"

"Meals will be served in your rooms. If you desire anything, ring the bell and some of the slaves will be sure to answer it. I am mostly in attendance upon my master, but whenever I am at liberty I will look after your comfort myself."

Again they thanked the strange boy, and he turned and left them. They could hear him whistle and sing as he returned along the passage. Then Princess Clia parted the curtains that her queen and companions might enter the Rose Chamber.
