"Never mind," said his mother. "You think that Bob will come back some time, and then the money will be of just as much use to us as though we had it now."

"If I could just find one more pearl I would be satisfied," replied Hank. "But I am almost afraid there isn't any more. Here's that Houston. Mother, I know he is the man that told father of it. He is the only one who overheard what Mr. Vollar said to Bob." And with the words he appeared at the door to hear what Houston had to say, for the man leaned upon the gate as if he was afraid to venture in.

"Good-morning," said Sam. "Is Mr. Lufkin about?"

"No, sir. He went away bright and early this morning, and nobody knows where he has gone."

Mr. Houston seemed surprised to hear it. He looked up and down the street, and finally moved away without saying another word. It was evident that he would have to hunt for the pearl-mine himself, for the sum he had received from Mr. Vollar wasn't going to last him always. He started back toward the village, and ran onto Joe Lufkin almost before he knew it. He seized Joe by the lapel of his coat and pulled him into a doorway out of sight. He knew that people would think it strange of him to be seen talking to such a man.

"Look here, Joe, what made you go off and leave me so suddenly this morning?" said Sam. "Have you been to see Gibbons about that money?"

"Yes, I have; and I won't go there again, I bet you. He talked to me as though I knew where Bob Nellis was. And he can't give me any money, either."

"What did I tell you? Now, the next best thing you can do is to call upon the president of the bank."

"And I won't go there, either. He says if I can't get along any other way I can go to the poor-house."

"Well, then, that thing is up stump, and there's nothing left but for you and me to go and hunt up that pearl-stream. I'll start with you now, if you want to."
