Bet's head was bent over the rock. She did not hear what was said. Suddenly she called, "Judge Breckenridge, do come here and look at these strange markings on the rock."
"Markings on a rock," said Joy Evans contemptuously. "I thought it was a tarantula or something."
"Well, you wouldn't have liked to see a tarantula any better than the markings, and these at least are not poisonous," Bet retorted.
Judge Breckenridge was examining the markings with interest, and gave a low whistle of astonishment. "This is the sort of thing one reads about. I'm wondering though if Kie Wicks put them here to fool you."
"It might be markings that tell of a buried treasure. See the arrow!
Look the way the arrow points."
"Yes, look the way the arrow points," mimicked Joy. "Now at last you have your mystery, Bet. I wish you joy of it. Follow the arrow and then you'll come to a tall cactus, and in the cactus you'll find a bullet…"
"Oh, keep quiet, Joy Evans!" flashed Bet angrily.
"We haven't found a mystery and I don't believe there is a treasure here. This is far away from Lost Canyon," said Kit.
"I'm going to believe in the treasure!" cried Bet, fired with enthusiasm at the prospect of finding something unusual. "Why, I could easily believe in a buried treasure. What's more I'll find it."
"I'm going to go and call Professor Gillette," called Enid, already in the saddle. "He can probably tell us what it means and what the Indians looked like who made the markings."
