"Well, then, Uncle Dunston, are my father and my sister alone in the world?"

"They are, excepting for me. We used to have other brothers, and a sister, but all of them are dead. I am alone here—an old bachelor."

"But you used to live with my father, is that it?"

"Yes, we were once in business together—owned a chemical works in New York and another in Chicago, and we also had some patents for manufacturing gas by a new process. But both of us liked to travel around, and so we sold out, and since that time we have been roaming around the world, sometimes together, and then again alone, although he always takes Laura with him, no matter where he goes. He is afraid to leave her behind, for fear she will be lost to him just as you were."

"Do you know his exact address now?"

"No; but I think a letter sent to a certain address in Paris will be forwarded to him. To tell the truth, I have been out here so long I have partly lost track of him. He will be amazed to hear from you, I am sure, and Laura will be surprised, too."

"I shall write to him as soon as possible," answered Dave.

"Of course! of course! And I will write too," rejoined Dunston Porter.

After that, sitting in the shade of the old temple and the palm trees, Dave and his chums told their story from beginning to end, and then Dunston Porter related some of his own experiences and told much more concerning Dave's father and sister Laura. He said that he and his twin brother looked somewhat alike, which accounted for Dave's resemblance to himself. He was glad to add that both he and his brother were well-to-do, so they could come and go as they pleased.

"As you know, I am hunting for a treasure of pearls and precious stones," said Dunston Porter. "So far, I have been unsuccessful, but I feel sure that I shall find them some day. And, even if I don't, the task of looking for the treasure pleases me and gives me the chance to visit many of these beautiful islands of the South Seas."
