"True enough, Trot," declared the sailor man. "What an idjut I was not to think o' that myself!"

In the royal banquet hall were assembled many of the mermaids, headed by the lovely queen, and as soon as their earth guests arrived, Aquareine ordered the meal to be served. The lobsters again waited upon the table, wearing little white caps and aprons which made them look very funny; but Trot was so hungry after her afternoon's excursion that she did not pay as much attention to the lobsters as she did to her supper, which was very delicious and consisted of many courses. A lobster spilled some soup on Cap'n Bill's bald head and made him yell for a minute, because it was hot and he had not expected it, but the queen apologized very sweetly for the awkwardness of her servants, and the sailor soon forgot all about the incident in his enjoyment of the meal.

After the feast ended, they all went to the big reception room, where some of the mermaids played upon harps while others sang pretty songs. They danced together, too—a graceful, swimming dance, so queer to the little girl that it interested and amused her greatly. Cap'n Bill seemed a bit bashful among so many beautiful mermaids, yet he was pleased when the queen offered him a place beside her throne, where he could see and hear all the delightful entertainment provided for the royal guests. He did not talk much, being a man of few words except when alone with Trot, but his light-blue eyes were big and round with wonder at the sights he saw.

Trot and the sailor man went to bed early and slept soundly upon their sponge-covered couches. The little girl never wakened until long after the sun was shining down through the glass roof of her room, and when she opened her eyes she was startled to find a number of big, small and middle-sized fishes staring at her through the glass. "That's one bad thing 'bout this mermaid palace," she said to herself. "It's too public. Ever'thing in the sea can look at you through the glass as much as it likes. I wouldn't mind fishes looking at me if they hadn't such big eyes, an'—goodness me! There's a monster that's all head! And there goes a fish with a sail on its back, an' here's old Mummercubble, I'm sure, for he's got a head just like a pig."

She might have watched the fishes on the roof for hours, had she not remembered it was late and breakfast must be ready. So she dressed and made her toilet, and swam down into the palace to find Cap'n Bill and the mermaids politely waiting for her to join them. The sea maidens were as fresh and lovely as ever, while each and all proved sweet tempered and merry, even at the breakfast table—and that is where people are cross, if they ever are. During the meal the queen said, "I shall take you this morning to the most interesting part of the ocean, where the largest and most remarkable sea creatures live. And we must visit King Anko, too, for the sea serpent would feel hurt and slighted if I did not bring my guests to call upon him."

"That will be nice," said Trot eagerly.

But Cap'n Bill asked, "Is there any danger, ma'am?"

"I think not," replied Queen Aquareine. "I cannot say that you will be exposed to any danger at all, so long as I'm with you. But we are going into the neighborhood of such fierce and even terrible beings which would attack you at once did they suspect you to be earth people. So in order to guard your safety, I intend to draw the Magic Circle around both of you before we start."

"What is the Magic Circle?" asked Trot.

"A fairy charm that prevents any enemy from touching you. No monster of the sea, however powerful, will be able to reach your body while you are protected by the Magic Circle," declared the Queen.
