"It will be a cake!" stated Weezie, calmly.

"Oh, if you know, then it isn't a surprise," said Rodney.

"Well, we know it will be a cake, for Grandma always bakes a cake on Monday when Lizzie has to do the washing," explained Weezie. "So that's why we know it's going to be a cake."

"But we don't know what kind," added Nat, "and that's where the surprise comes in. We never know whether it will be a chocolate cake, or a cocoanut cake or an orange short-cake or what kind of a cake it will be."

"Any kind of a cake is good," declared Rodney, "but I like chocolate best."

"So do I," agreed Nat. "Anyhow, when we come home from school we'll know what kind it is."

"I'll save my piece to take with us when we go fishing," said Rodney. "We'll play we're explorers in the woods, Nat, and that all we have to eat is cake!"

"That'll be fun!" agreed his chum.

"Maybe Grandma will give you boys two pieces of cake," suggested Weezie, as the children hurried on along the street, for they could hear the ringing of the school bell. "You could eat one piece right away and save the other to take fishing with you."

"That would be the best ever!" cried Rodney.
