all about the location work that had to be done. While the
arrow pointed southwesterly and showed the direction in which to look,
it pointed over a deserted country that stretched for miles into Mexico.

"If there is anything thrilling about this, I'd like to be shown,"
pouted Joy. And in sheer boredom she got up, walked to a rocky ledge
and scrambled up the steep face of it.

Enid and Shirley, who were watching the professor studying the markings
on the rock, heard a cry of surprise from Joy, but before they could
turn toward her, they saw her falling, clutching wildly at the ledges
in an attempt to save herself.

Joy had turned her head to speak to her friends and had missed her
footing. As she touched the ground, her ankle bent under her and she
fell with a groan.

Bet ran to her help. "Speak, Joy, speak to me," we said shaking the
girl. Joy's face was deathly white but her eyes fluttered open and
seeing Bet she cried hysterically:

"I found it! I found it!"

seemed to credit Joy's story.

"Why, really, I don't know. I never thought to notice. I saw an arrow
and I think it was pointing toward that hill over there--but then again
it might be pointing away from it. I'm not sure." Joy stopped
helplessly, and clutched her aching foot.

"You're helpful at least," Kit shrugged her shoulders. "I do believe
she's just teasing us. Joy would never find anything!"

"Then go and see for yourself!" snapped Joy.

"I'll do it," replied Bet suddenly letting go of Joy in her excitement.
Joy collapsed with a groan.

Bet turned to help her but Enid shoved her aside. "Here is where I
shine. You go and
