"Well, that's over," said Sammy, a few days after their return from their unexpected voyage to sea. "Now if we could only find the pirate gold, we'd be all right."
"Oh, you're foolish!" exclaimed Frank. "There never was any pirate gold."
"Well, what was Professor Watson digging for?" demanded Sammy.
"I don't know," said Frank, "But it wasn't gold."
"There he is now, digging again," said Bob, quickly, "and he's on our beach, too. I guess now we've got a right to ask him what he's after."
Rather bashfully the boys approached the old man. He paid no attention to them, but went on digging. Suddenly he was observed to throw aside his shovel, make a grab for something in the sand, and then he cried out:
"I have it! I have it! At last I have found it!"
Eagerly the boys rushed forward. The man did not seem to notice them, but was closely looking at something in his hand.
"Have you found the pirate gold?" asked Bob, boldly.
