"It's all right," said Fatty. "I've got a big envelope here — see? Now then, let's each put into the envelope the same thing that we've already settled for dues. I'll put in two cigar-ends, to match the ones I've left. Daisy, put in your other half of ribbon."

Daisy did so. Then Bets put in one of the blue doll's buttons, Larry put in the other shoe-lace, and Pip put in a peppermint drop.

Fatty folded up the envelope carefully and put it into his pocket. "If any of us is accused of the theft, because of the clues we've put in the cage, we've only got to show them what's in this envelope for them to know we did it for a joke," he said.

A bell rang out in Pip's house, and Bets gave a groan. "That's my bed-time bell. Blow! I don't want to go."

"You must," said Pip. "You got into a row yesterday for being late. Oh dear, I do wish we could stay here and see old Clear-Orf and Tupping finding the dues we've left!"

"Well, let's," said Larry.

"Oh, me too!" wailed Bets, afraid of being left out again. Pip give her a push.

"Bets, you must go! There's your bell again."

"Well, it's your bell too — it means you've got to come in and wash and change into your suit for supper-time," said Bets. "You know it does."

Pip did know it. Larry gave a sigh. He knew that he and Daisy ought to go home too. They had farther to go than Pip and Bets.
