"Oh, yes, twinnies, I think you'll go, all right. Hurry now, for you must be back in time to help me get supper. Fairy'll have to straighten the front room, and we won't have time. Run along, and be quick."

For a few seconds the twins gazed at each other studiously. Neither spoke. Without a word, they went up-stairs to prepare for their errand.

They whispered softly going through the upper hall.

"We'd better make a list," said Carol softly.

So with heads close together they wrote out several items on a piece of paper.

"It'll cost quite a lot," objected Carol. "Thirty cents, anyhow. And Prudence'll make us pay for the oysters, sure. Remember that."

"We'd better let Connie in, too," suggested Lark.

Connie was hastily summoned, and the twins whispered explanations in her willing ears. "Good!" she said approvingly. "It'll serve 'em right."

"But it'll cost money," said Carol. "How much have you got?"

Then Connie understood why she had been consulted. The twins always invited her to join their enterprises when money was required.
