"And now what shall we girls do?" asked Betty, after breakfast.

"What do the boys want to do?" queried Mollie. "Perhaps you may have some plans for us."

"Sorry, ladies," Allen said, "but our boat is on a strike again, and we'll have to have it fixed. It isn't much, though, and we can go out this afternoon."

"Then we'll go down on the beach for a while," proposed Betty. "It's lovely this morning. We'll go in bathing just before luncheon, and then, after a little sleep, we'll be ready to have the boys amuse us."

"Sounds nice, to hear them tell us," commented Roy with a laugh.

And this plan was followed. When the boys went off in the motor boat, the ignition system of which was not working to their satisfaction, the girls strolled down to the shore, walking along it.

"Let's go as far as the place we found the diamonds," proposed Amy.

"Think you might find some more?" asked Betty, with a smile.

"No such luck. But I thought perhaps we might see——"

"Those men again? No, thank you!" cried Grace.
