“Well, if there’s a treasure here we don’t want to leave it behind,” said Mr. Brown. “Your father seemed very anxious about it, Harry. Let’s have a look at it.”

When they reached the deckhouse a little later and opened Mr. Philip Pott’s chest, the treasure was found to be a lot of old-fashioned silver dishes—a teapot, a sugar bowl, a coffee urn, and such things as that.

“Oh, what wonderful silver!” cried Mrs. Brown when she saw it. “That is, indeed, a treasure! Where did it come from?”

“That silver has been in our family a long time,” said Harry. “Just before my father and I sailed together on the Mary Bell an old aunt of father’s died and gave us this silver. I didn’t think much about it, and I didn’t know my father called it his treasure until you people mentioned it. I don’t believe it’s worth much—old silver like that.”

“Oh, indeed, it is worth a lot of money!” said Mrs. Brown. “It is very beautiful and old. Dealers will give a lot for that.”

“Well, we’ll have it put on board the Beacon and kept safely for Mr. Pott,” said Captain Ward. “And now I think we had better get back to the ship, for there may be another storm or a fog and I don’t want to get caught on the sand-bar again.”

A little later the castaways, including Harry Pott and his chest of silver, were rowed out to the Beacon and soon the vessel was steaming on her way again.

“Good-by, Cocoanut Island!” called Sue, waving her hands over the rail to the place where they had had so many strange adventures.

“Good-by!” echoed Bunny Brown. “Now we’re on the rolling ocean again!”

Mr. Harry Pott was well taken care of on board the steamer. His hair and beard were trimmed and he was given some clothes to replace the ones made ragged by his lonely life of a year on the island.
