"What's the riddle, Laddie?" asked Vi, shaking her curly hair and looking up with her gray eyes at her brother, whose locks were of the same color, though not quite so curly as his twin's.
"There she goes again! Asking more questions!" exclaimed Rose, who had come back from putting away the broom, and was ready to play the steamboat game with her older brother.
"But what is the riddle?" insisted Vi. "I like to guess 'em, Laddie! What is it?"
"What kind of a wheel doesn't go 'round?" asked Laddie again, smiling at his brothers and sisters as though the riddle was a very hard one indeed.
"Pooh! All wheels go around—'ceptin' this one, maybe," said Russ. "And this is only a make-believe wheel. It's the nearest like a steamboat paddle-wheel I could find," and he gave the footstool a little kick. "But all kinds of wheels go around, Laddie."
"No, they don't," exclaimed the little fellow. "That's a riddle! What kind of a wheel doesn't go 'round?"
"Oh, let's give it up," proposed Rose. "Tell us, Laddie, and then we'll get in the make-believe steamboat Russ has made, and we'll have a ride. What kind of a wheel doesn't go around?"
"A wheelbarrow doesn't go 'round!" laughed Laddie.
"Oh, it does so!" cried Rose. "The wheel goes around."
"But the barrow doesn't—that's the part you put things in," went on Laddie. "That doesn't go 'round. You have to push it."
