“Nope,” there was a suggestion of mystery in his voice. “We hid it. Joe and I hid that mine.”

After that day, more than ever before, the girl wanted to go in search of that mine. Go where? Ah! that was the question.

The answer came two days later and in a rather strange manner. A young scientist, a member of the Geological Survey, showed her a series of enlarged photographs taken from the air.

“They cover hundreds of square miles back there in the great unknown,” he explained. “See! Rivers, lakes, tundra, mountains, everything.”

“Everything!” the girl had been struck with an idea. “Loan them to me for an hour.”

“Right,” the young man agreed. “Two hours if you like.”

Fifteen minutes later she tore into Tom Kennedy’s cabin acting like a mad person. Pushing a table into the kitchen, throwing chairs on the bed in the small back room, she at last cleared the living room floor. Then, while her grandfather stared she thumb-tacked sheet after sheet of paper to the floor until there was no longer room to stand.

“There,” she panted. “There it all is, mountains, lakes, rivers, tundra, everything. Here is Nome,” she pointed. “There is Sawtooth Mountain. Now, where was your mine?”

For a full quarter hour, as the tin clock in the corner ticked the minutes away, the gray-haired prospector’s eyes moved back and forth across that map, then, with a sudden gasp, he exclaimed:

“There it is! Right there. Well up on the middle fork of that river. I’d swear to it if it was the last word I ever said. Girl, you’re a wonder!” Suddenly he threw his long arms about her and kissed her on the cheek.
