"I think it is all foolishness anyway," Joy exclaimed. "What we want now is that treasure, and instead of looking for it, you are going to dig a well."

Kit laughed as she always did at Joy's mistakes. "Call it a well if you want to," she said patronizingly, "but don't let Tommy Sharpe or Seedy Saunders hear you say it. They'll tease you unmercifully."

"It's this way, Joy," explained Bet, impatiently. "Kie Wicks might get wise to it, and come in at the end of two months and snap up this claim too, if we haven't done our work. That has to be done within two months."

"Then he'd get the stone with the markings?"

"Yes, that's it. And he might find the treasure, if we don't watch out," added Kit.

"Then let's get to work at once!" cried Joy, digging her spur into Dolly's side.

"You mean, Professor Gillette will get to work at once while you and the rest of us stand around and look pretty," said Enid.

"Why we don't mean any such a thing, Enid Breckenridge. I'm perfectly willing to work and do my share," snapped Bet, her face red with anger.

"I'll not have Professor Gillette imposed on like that."

"We'll all do what we can," soothed Kit. "Although I'm not sure we'll make much headway with the pick and shovel."

"I think we should have a Mexican do the work, girls," said Enid.

"He'd do it in half the time."

"Professor Gillette said it was better not to have anyone else around for a while until we could find out something about this treasure," Bet said. "So we might as well make up our minds to dig right in and work hard."

Once on the site of the claim, the professor unloaded his tools and looked about for a suitable place to put down the ten-foot shaft. His knowledge of mining was not very great but he and Kit finally decided on the best spot.

The old man started in at once, swinging the pick as if it were a hammer. He soon dug away the thin layer of earth and crushed rock, and reached solid stone.

"It's a good thing I brought the drills along!" the professor threw down his pick and took up a drill and heavy hammer.

"Isn't it exciting!" cried Bet. "Do let me try to use the drill.

"All in good time, child, all in good time," he promised her as he adjusted the tool. "This is a two-man job anyway. Somebody has to help me."

Bet crouched down close beside him and held the drill steady while the old man prepared to hit. She glanced up at him, dubiously. The old man laughed.

"Don't know as I blame you any," he said as he twisted a piece of heavy wire about the drill and gave Bet an end to hold. "There, you can steady it with that, so I won't hit your fingers."

"Oh, I wasn't afraid," began Bet but the professor laughed and Bet did not finish her sentence.

"You looked as if you were very much frightened indeed. You were certain I would hit your fingers, and I'm not sure I wouldn't have," he chuckled.

And his first strong blow did miss the drill and the girls, watching him, laughed.

"Gee, if Bet's fingers had been there!" gasped Joy.

"Well, maybe I'd have been more careful if her hand had been there. I never take chances."

While Bet held the drill in place the professor dealt blow after blow until he was ready to drop with exhaustion.

"And some men keep that up all day, I'm told," he gasped as he threw down the tool and dropped to the ground. "I don't believe they do," he added.

"I've seen men keep at it pretty steadily for hours," interrupted Kit, "but they don't go at it so strenuously. You put all your soul and body into it. They don't get excited and they don't wear themselves out with wild flourishes. You see when a prospector has that work to do, he doesn't have to hurry. He has all the time there is."

"To tell you the truth," laughed the professor sheepishly, "I'm so anxious to start looking for the treasure that I don't want to dig this shaft, I'm like a child with a new toy."

"Come here, Kit," called Bet. "You hold this drill for a while and let me swing the hammer. I'm just dying to do it."

"And maybe I'm not glad there is a wire to hold. You'd hit me, sure."

"Don't trust me even yet," Bet returned with a gay laugh.

"That's right, Kit," trilled Joy. "You are only two feet away from her hammer, she might easily miss the mark by that much." Joy was glad of a chance to tease Bet.

Bet swung the hammer with vigor, bringing it down on the drill with a force that seemed impossible from her slender arms.

"Go it, Bet. You'll get there yet," shouted Joy.

Bet was soon worn out and the girls took turns and had the joy of finishing one hole to the required depth for setting the charge.

The professor was bending over the tracings on the rock. He had forgotten 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!"

"Found what, Joy? What did you find?"

"Another arrow. Right there on the rock!" Joy was struggling to her feet, but at the attempt she fell back with a groan.

"For the love of Mike, is that all? Why, Joy Evans, you'd get so excited over an arrowhead that you'd lose your footing!" Kit cried.

"I thought you had more sense than that."

Between clenched teeth Joy answered, "It wasn't an arrowhead! It was an arrow carved on the rock."

"Don't be silly, Joy. You're dreaming!" laughed Kit.

"If I thought you were just teasing me, Joy, I wouldn't be sorry about your poor foot." Bet stared at the girl with a threatening look. "It isn't nice to tease about things as serious as hidden treasure."

"But the arrow's there," Joy answered.

"Which way did it point?" asked Professor Gillette, the only one who seemed to credit Joy's story.
