he Judge. "If he
had been there, surely there would have been some sign."

"I have an idea!" cried Bet, jumping to her feet. "I believe he's in
that hut, they put him back after you'd been there. I'm going to find
him tonight."

"You'll do no such thing, Bet. Chasing around among a lot of bad men
is no place for a girl," began her father, but Bet interrupted:

"Just wait until I have worked out my plan and you'll see I'll be as
safe as if I were at home. You can come with me, Dad. Will you help
me, Judge? I'll need several men."

"Let us in on this," exclaimed Phil and Bob in the same breath. "We'd
like to have a hand in solving your latest mystery."

Bet flew to her room and returned in a few minutes in a strange
costume, a long dress of buckskin. Dark braids fell over her shoulders
and feathers rose from her hair. She had no resemblance to the boyish
girl they knew.

The Colonel looked puzzled but Judge Breckenridge caught the idea.
"You're a wonder, Bet! And I do believe you are right. You'll be as
safe as if you were in your own bed."

An hour later, the watchers by the hut rubbed their eyes and stared
about them. A wild, weird cry rang through the canyon, and in the
moonlight Kie Wicks and his bad men saw, far above them on the cliff,
the figure of an Indian girl.

"She wasn't walking, she was just floating in the air, it seemed, and
as she moved, she moaned and shrieked. It was terrible! There was no
doubt about it. It was the ghost," Kie Wicks told his wife when he was
safely at home.

"What happened?" Maude urged him to continue the story.

"You should have seen those Indians go! 'The Old Chief's daughter
walks! It's the ghost girl!' they cried hoarsely. And that's the last
I saw of them."

"And what did you do?" Maude pressed him further.

"I--well, I ran, too. I got out of there in record time, let me tell
you. I don't mind shooting it out with a human being, but I don't take
no chances with a ghost. I vamoosed."

"And the old man?" she inquired.

"He's there yet. One thing certain, I'll never go into that canyon
late at night again."

Bet's ruse had worked better than she had hoped. In less than two
minutes after she stepped out on the cliff, the place was deserted, the
hut left unguarded and Judge Breckenridge and his men rushed in, broke
open the door and found the old man asleep on a sack of straw.

The Judge touched him and the professor tried to shake him off
