"I'm not so sure about that. I don't want you to go up. You'll have plenty of other fun." "I wanted to go up in the balloon," and Bert sighed in disappointment. "We'll go look at it, anyhow," suggested Harry. "I want a ride on a lion!" insisted Freddie. "So do I!" added Flossie. "All right, I'll take you children to the merry-go-round," said Mr. Bobbsey. "You come there and meet us after you finish looking at the balloon and the airship," he said to Bert and Harry. "I'll stay with you, Daddy," said Nan. "I want a ride on the merry-go-round, too," and she laughed. They could hear the music of the "carrousel," as a merry-go-round is sometimes called. "Come on!" urged Flossie and Freddie, tugging at their father's hands. He led them over to the crowd that surrounded the machine on which a whirling ride could be had for five cents. "This way! This way for the merry-go-round!" cried a boy's voice. "Only five cents a ride! Get your tickets and take a ride! On an elephant or a tiger!" "I want a lion!" cried Freddie. "All right! This way for your lions!" cried the voice. Mr. Bobbsey, pushing his way through the crowd with the children, saw Bob Guess on the merry-go-round. The boy was helping children to their seats on the wooden animals, strapping them safely so they would be ready when the machinery started. The organ kept on playing all the while. "Hello, Bob!" called Nan, as she climbed up on a wooden horse, while Flossie and Freddie, with their father, looked for lions. The strange boy glanced up in some surprise. But when he saw Nan a smile came over his rather sad face. "Oh, hello!" he said. "How did you get here?" "We came just now in my father's auto. Do you run the merry-go-round?" "I help when Mr. Blipper isn't here. I take up the tickets after she starts. Have you got your tickets?" "Yes, daddy bought them. My little brother and sister want to ride on lions." "There's a pair right behind you," said Bob Guess. Nan turned and saw her father just finishing the strapping up of Flossie and Freddie each on a big wooden lion. The small twins were smiling with delight. "Gid-dap!" called Flossie to her lion. "You shouldn't say 'gid-dap' to a lion," objected Freddie. "What should you say?" asked Flossie, turning to look at her brother. "You ought to say--now--er--'Scat!'" "That's what you say to a cat!" declared Flossie. "Well, then say 'Boo!' I guess that's what you say to a lion," went on Freddie. "Say 'Boo!'" The little girl looked doubtful. "All right. Boo!" cried Flossie, after a moment. It was not quite time, however, for the merry-go-round to start. Mr. Bobbsey made his way along the platform to Bob, who stood near Nan. "Where is Mr. Blipper?" asked Mr. Bobbsey. "I want to see him." "He's away to-day, Mr. Bobbsey," was the answer. "Away! Oh, I am sorry," was the reply of the Bobbsey twins' father. "This is his day off," went on the lad. "Will he be here to-morrow?"
