There was a hurried and whispered conference out on the porch and an admonition from Polly, "remember no one is to say a word, except Margy to me," and then the picnic preparations went ahead with a rush.

Perhaps the older folks were a little surprised that evening after supper to see Carrie and Mattie come up the path. But the Riddle Club members were not surprised.

"We thought we'd come over for a little while," said Carrie blandly. "It is such a lovely evening, don't you want to take a walk on the beach?"

It was on the tip of Jess's tongue to say she was tired and that they expected to get up early in the morning, but she stopped in time. Margy spoke of the next day.

"I don't believe I'll go," she drawled lazily. "I'm tired from working so hard to-day, getting ready for to-morrow. I want to get to bed early."

Carrie said nothing, but she exchanged a glance with Mattie.

"You won't forget to call me, will you, Polly?" went on Margy clearly.

"No, I won't forget," Polly promised. "What time shall I call you?"

Margy appeared to be thinking. Fred pinched Artie gently as a reminder to keep still.
