"That means I must go as chaperon," sighed Mrs. Tupper.

"I'll be chaperon," laughed Sybil; "but as we shall go and return in a couple of hours I don't believe Madeline will really need one."

"You shall stay comfortably on the yacht, Aunt Anna," said Madeline. "Who else wants to go? We can carry six, you know."

It was soon arranged to add Mr. Radley-Todd and Orissa to the four, thus completing the complement of the launch.

Just before they set off Monsieur Rissette, the alert chef, appeared with his hamper of lunch, for he had an established idea that no one should depart, even on an hour's journey, without a proper supply of food. Then, merrily waving adieus to those on board, the explorers glided out of the bay into the open sea.

Rounding the north end of their islet they saw clearly the large island ahead, and Steve headed the launch directly toward it.

The trip consumed rather more than the hour Orissa had figured on, but it was a light-hearted, joyous party, and they beguiled the way with conversation and laughter.

"I am quite sure," said Madeline, "that I am enjoying this experience far more than I would a trip to Hawaii. Think of it! A chase, a rescue and a wreck, all included in one adventure. I'm rather sorry it's about over and we are to return to civilization."

"Sybil and I have had a glorious time," added Orissa. "Barring the fact that we were a bit worried over our fate, those days when we played Crusoe and Columbus on a forsaken island were full of interest and excitement. I know now that I enjoyed it thoroughly."
