“Without doubt,” said the boy, communing with himself, “the papers were brought aboard the brig just as this rascally Wetherbee said, and they were from Uncle Anson. Let’s see, he said he died at Kimberley—why, that’s right at the diamond mines!” For like most boys with adventurous spirits and well developed imagination, Brandon had devoured much that had been written about the wonderful diamond diggings of South Africa.

“Perhaps—who knows?” his thoughts ran on, “Uncle Anson ‘struck it rich’ at the diamond mines before he died. There’s nothing impossible in that—excepting the long run of ill luck which had cursed this family.”

He shook his head thoughtfully.

“If Uncle Anson had owned a share in a paying diamond mine, this rascally sailor would have known at once that the papers relating to it could not benefit him, for the ownership would be on record there in Kimberley. It must, therefore, be that the property—whatever it may be—is in such shape that it can be removed from place to place—perhaps was brought aboard the brig by the friend of Uncle Anson who told father of his death.”

For the moment the idea did not assist in the explanation of the course of Caleb Wetherbee in retaining the papers. But Brandon had set himself to the task of reasoning out the mystery, and when one thread failed him he took up another.

“One would think,” he muttered, “that if there had been any money brought aboard the brig, father would have taken it on the raft with him when they left; but still, would he?

“According to the report the brig grounded on Reef Number 8, and perhaps was not hurt below the water line. The next gale from the west’ard blew her off again. She is now a derelict, and if the money was hidden on board it would be there now!”

At this sudden thought Brandon sprang up in excitement and paced up and down the path.

He had often heard of the wrecks of vessels abandoned in mid ocean floating thousands of miles without a hand to guide their helms, a menace and danger to all other craft. The Silver Swan might float for months—aye, for years; such a thing was possible.

“And if the money—if it is money—is hidden aboard the brig, the one who finds the derelict first will have it,” was the thought which came to him.
