"No!" exclaimed Mr. Bobbsey, who was not so worried, now that he saw the Aquarium man on his way to get Freddie. "One turtle ride is enough for the family. Hold fast, Freddie!" he called, as the turtle came around on the side of the pool near to where the Bobbseys stood.

By this time the man was out on the middle of the wooden piece that held the heavy wire netting, and as the turtle swam near that the man leaned over and quickly lifted Freddie from the swimming creature's back.

"There you are, my boy!" cried the man, as he held Freddie out to another attendant who had come to help. "Now you're all right except for wet feet, and we can dry them for you in the engine room."

"We have to keep the boilers going in Winter to warm the water for the tropical fish," said the man to Mr. Bobbsey. "Take your little boy there and we'll dry his shoes and stockings."

"Thank you," said Mr. Bobbsey. By this time Freddie was safely out of the turtle pool, and the big creature, relieved of that strange thing on his back, had sunk down to the bottom of the pool, as though to hide away. It was lucky he had kept himself afloat as long as he had, or Freddie might have been wet all over.

"Well, you do seem to have the queerest things happen to you, Freddie," said his father with a smile. "What will you do next?"

"I—I couldn't help this, Daddy," said the little fellow. "I—I just slipped!"

"Well, don't do it again," said the Aquarium man, with a smile. "If you had fallen in the other pool, where there are half a dozen turtles, though none as large as the one you rode on, you might have been bitten. But you're all right. Now come along and we'll dry you out."

It was an easy matter to dry Freddie's feet and legs in front of the warm furnaces in the boiler room, but his shoes and stockings did not get rid of their wetness so soon. And, as Mr. Bobbsey did not want to wait, he sent one of the attendants out to buy new shoes and stockings for his son. With these on, and carrying the damp ones in a bundle, Freddie was soon ready to go home.

"I guess I've had enough of the 'quarium," he said. "Anyhow I had a funny ride."
