"Ward," she said suddenly, "why must the model of a boat be always correct?"

Larry leaned forward, his oily rag poised in mid-air.

"That a riddle?" he demanded. "I used to be a great hand for riddles when I was young."

"You did?" Polly beamed. "Oh, perhaps you know some new ones. We have a Riddle Club, you know, and we love to hear new riddles."

Larry had to hear about the Riddle Club then and there, and even Ward forgot the tantalizing nearness of the lunches. Larry had never heard of a riddle club, but he thought it was a fine plan and said he would like to come to a meeting some day.

"We're not holding regular meetings this summer," Fred explained. "But if you ever come to River Bend, you be sure and come and see our clubrooms. We have two—a winter one and a spring and summer one."

Then Larry suggested that Ward had not answered the riddle Polly had given.

"Why must the model of a boat be always correct?" Polly repeated.

"So folks can sail it and not have it sink," said Ward.

"Now, is that any kind of an answer?" Polly demanded patiently.
