"But what could that be?" asked Robbie in surprise.

"Well, I have thought of something," said Mamie, "but I am afraid you will laugh at me if I tell you."

"Oh no, I won't," cried Robbie. "Do tell me what it is."

"I shall tell you," said Mamie, "if you promise faithfully not to laugh."

"I promise faithfully," answered Robbie.
