“Is this a circus?” asked Blackie.

“That’s what it is,” answered Dido. “Don’t you see Tum Tum, the jolly elephant over there?” and Dido pointed his paw at the big creature. “Whenever you see an elephant that is a circus or a menagerie.”

“Is he an elephant?” Blackie asked, looking at the big animal.

“Yes, and his name is Tum Tum. He is the most jolly elephant you ever knew, always laughing and eating peanuts. He’s in a book, too.”

“What do you mean—in a book?”

“I mean somebody wrote a story-book about Tum Tum, who had many adventures. I think I’m going to be in a book some day.”

“That will be nice,” said Blackie, who was not quite so frightened now. “Did you ever hear of a cat being in a book? I have had some adventures that might do for a book,” and she told Dido, the dancing bear, about them.

“I don’t know,” answered Dido. “I once knew a dog, named Don, who was in a story book. He was a runaway dog, too, he told me. So he must be something like you. If somebody wrote a book about a runaway dog I don’t see why he couldn’t write one about a lost cat.”
