"A book, eh? Like as not some sort of diary. I've never heard you talk much about the old fellow; was he educated at all, and could he write d'ye think?" demanded his comrade, with awakening interest.

"Sure he could. Well, what did I tell yo? It's a book all right, and p'raps old The kept a record of the fish and muskies he caught winter and summer. He was a queer old duck, though he did seem to think a heap of me. Wow! look at that, would you!"

Thad's startled exclamation was not in the least surprising, considering what had happened.

As he idly opened the book there was disclosed a little collection of genuine government yellowback bills, not one of which was less than ten dollars in its denomination. No wonder both boys stared, their eyes seemingly "as big as saucers," as Thad afterwards described it.

Mechanically Thad began to count the money that had come into their possession so miraculously.

"Three hundred and thirty dollars! Did you ever hear of such luck in all your born days?" he said, his face lighting up with delight.

"But it isn't ours, you know, Thad. He gave you the boat, but how do we know he ever meant you to have this money? Can't you just remember something that would explain it all? Didn't he say just a little to you at some time about it?"

Maurice looked anxiously from the pile of bills to Thad's sober face, as though urging him to exert himself to the limit to bring back to his mind some clue that would unravel the mystery.

And Thad suddenly became anxious himself; he cast a quick look toward the little window of the shanty-boat cabin, just as if oppressed with a fear that hostile eyes might even then fee fastened upon them.

So quickly does the possession of riches bring new troubles; up to that moment such a thing as a possible intruder had been far from occurring to Thad; but circumstances alter cases, and now they had something worth stealing—and he grew afraid.
