To-morrow one last trip to the cave, and then hey, for home and
Helen!

The diary ended here.

I closed the book, and stared with unseeing eyes into the green shadows of the encompassing woods. What happened to the writer of the diary on that last trip to the cave? For he had never left the island. Crusoe was here to prove it, as well as the wreck of the Island Queen. And, in all human probability, under the sand which choked the cabin of the derelict was the long-sought chest of Spanish doubloons.

But what was the mysterious fate of Peter? Had he fallen, overboard from the sloop and been drowned? Had he returned to the cave—and was he there still? It was all a mystery—but a mystery which I burned to solve.

Of course I might have solved it, very quickly, merely by communicating the extraordinary knowledge which had come to me to my companions. But for the present at least I meant to keep this astounding secret for my own. Somehow or other, by guile or lucky circumstance, I must bring it about that the document I had signed at Miss Browne's behest was canceled. Was I, who all unaided had discovered, or as good as discovered, the vainly-sought-for treasure, to disclose its whereabouts to those who would deny me the smallest claim upon its contents? Was I to see all those "fair, shining golden coins," parceled out between Miss Browne, and Mr. Tubbs, and Captain Magnus (the three who loomed large in my indignant thoughts), and not possess a single one myself? Or perhaps accept a little stingy present of a few? I really wasn't very covetous about the money, taken just as money; but considered as buried treasure it made my mouth water.

Then besides, while I kept my secret I had power; everybody's destiny was in my hands. This was a sweet thought. I felt that I should enjoy going about with a deceptive meekness, and taking the severest snubs from Miss Browne, knowing that at any moment I could blossom forth into the most exalted and thrilling importance. Also, not only did I want a share in the treasure myself, but I wanted, if possible, to divide it up on a different basis from the present. I wanted Cuthbert Vane to have a lot of it—and I should have been much better pleased not to let Mr. Tubbs or Captain Magnus have any. I did not crave to enrich Violet, and I thought Aunt Jane had already more money than was good for her. Give her another half-million, and Mr. Tubbs would commit bigamy, if necessary, for her sake.

And then there was Dugald Shaw, who had saved my life, and who seemed to have forgotten it, and that I had ever had my arms about his neck—and who was poor—and brave—

Yes, decidedly, I should keep my secret yet while, till I saw how the cards were going to fall.
