"Who is it?" asked Tom, laying aside a pressure gauge he intended attaching to the gun.
"He says his name is Peterson—Alec Peterson. Do you want to see him?"
"Yes, let him come up," directed the young inventor. "Do you hear that, Ned?" he called. "Our fortune-hunting friend is here."
"Maybe he's found that lost opal mine," suggested Ned.
"I hope he has, for dad's sake," went on Tom. "Hello, Mr. Peterson!" he called, as he noticed the old prospector coming along. "Have you had any luck?"
"I heard you were down here," said the man, not answering the question directly, "and as I had to run over from my island for some supplies I thought I'd stop and see you. How are you?" and he shook hands.
"Fine!" answered Tom. "Have you found the lost mine yet?"
Alec Peterson paused a moment Then he said slowly:
"No, Tom, I haven't succeeded in locating the mine yet. But I—I expect to any day now!" he added, hastily.
