Gene slept on a cot in the kitchen, and as the days passed his strength rapidly returned. The weather continued sunny and bracing and although it was nearing the holiday season the midwinter blizzards had not arrived.

Muriel had told the lad all about the treasure box in her cave. A week after the arrival of the boy on Windy Island they were climbing about on the cliffs when they found themselves near the small opening to the cave. “Come on in. I’ll show yo’ the box,” Rilla said.

Gene, really curious concerning the treasure that had been given up by the sea, went in and watched with interest as the girl lifted the mirror-lined cover of what he recognized to be a water-tight steamer trunk of foreign make.

The sea-green dress, he agreed, was wonderful. “I judge that it is Parisian,” he said. Then, as he saw the question in her hazel eyes, he told about the City of Paris, where he had been the summer before. He described the beautiful shops, the lights, the damsels, and the rare and exquisite fabrics from which their gowns were fashioned.

“I reckon this box belongs to one of those beautiful ladies,” Muriel said at last.

Gene nodded. “I haven’t a doubt about it,” he agreed. “Have you looked through it thoroughly to see if you could find the name of the owner?”

The girl shook her red-brown head. “I cal’lated thar’d been a wreck, for ’twas a high storm as sent this box in. ’Twa’n’t hereabouts, but I reckon it was far out at sea.”

“Undoubtedly you are right, Muriel, but let’s look for some possible clue as to the former owner’s identity.”

The lad and the girl, as eager as two children, were on their knees in the soft sand of the cave. The dress had been carefully laid to one side. A small box of exquisite workmanship was found and when the cover was lifted the girl uttered an exclamation of joy, and in the dim light Gene thought her eyes like stars.

No wonder that Muriel was elated, for in that box there was a set of jewels of the most entrancing blue. Never had she seen anything just like it in the sea or in the sky. It seemed to be alive, that color! There was a necklace of them and two lantern-like earrings, a brooch and a ring.
