"They might," Mollie admitted. "But they would hardly go so far away."

"Let's look on the other side," proposed Grace. But that beach, of the little arm of land that jutted out into the bay and ocean, showed no sight of Betty and Amy.

"Oh, I—I'm getting—worried," returned practical Mollie. "Nothing could have happened, unless one of them sprained her ankle, or something like that, and can't walk. Even then the beach is so open, and there isn't a place on it that one need fear——"

"Unless it's that old fisherman's hut," broke in Grace.

"Oh," observed Mollie, slowly, and there came a change over her face. "I didn't think of that. Yes, they might——"

She was interrupted by a shrill whistle, as if of some boat. Both girls turned quickly, and the same exclamation came to the lips of both.

"The boys!"

It was the Pocohontas approaching, and Allen, Roy and Henry waved their hands as they came on swiftly over the blue waters.

"Are they in the boat?" asked Grace.

"Who?" Mollie wanted to know.
