“Amnesia,” Tom shouted.

“Pardon me, my error. I’ve heard him say that such people are sometimes cured by an operation after years. All right, then, I don’t see any reason why he shouldn’t come back here and get his money, if he remembers now where he put it. If he comes it will be mighty interesting to see him and help him. If he doesn’t come, we’re having a mighty good vacation, anyway. I’m here as a scientific observer. I don’t care anything about hunting for treasure; I had my little fling to-day and I’m through. If Captain Kidd’s ghost came and told me where his pirate gold was, I’d say, ‘Nothing doing, go dig in the sand yourself.’

“But I’d just kind of like to see if that old codger does come back here, like an old dog that can’t forget a place. If that old fellow is Mink Havers, I’d like to see him and give him a hand—and, as you say, see that the kid gets her share. But if it’s just a case of digging, I’d rather take my little pail and shovel and go down to Coney Island. So much for that. If you want to vacuum clean the Gulch go ahead and do it.

“What’s interesting me just at present are two things to wit, wiz. I’d like to know who was wandering around up at the top of the well to-night, before you came. And I’d like to know—Potato? No?—I’d like to know who it was that ran away from the Ford. If he really intended to steal your Ford, that would prove conclusively that he was John Mink, alias Treasure Jack. Because anybody who would want to steal your Ford must be plumb crazy; I don’t know if you’d call it magnesia or amnesia or what.”

“It was a young man,” said Tom; “he ran like an athlete.”

“He had gray hair?”

“Yes, but lots of young men have that; fellows that think a lot⸺”

“I think a great deal,” said Brent. “I’m always buried in thought when I’m not buried in a well. And my hair is wavy brown.”

“That fellow wasn’t Mink,” laughed Tom.

“And the other—the sound up above the well?”
