lies,” Gale said candidly. “Do you?”

“It is back of some place,” Phyllis said uneasily. “We’ve got to find it.”

“We’ve got to find it if we want to get out,” Gale agreed. “Suppose we turn around and walk the other way.”

A mocking laugh arose from somewhere in the passage and echoed loudly and weirdly. Both girls shivered from the ominous tone of it. They walked along, Phyllis’ hand against the wall to guide them, but soon her hand touched empty air.

“There’s a turn here,” she cautioned.

“It’s a cross passage,” Gale said. “Passages on both sides of us, but which one do we take?”

Again that taunting laugh rumbled from behind them.

“Whichever way we go, I hope it is away from him,” Phyllis declared trembling. “That laugh gives me the jitters, it is so melodramatic. Soon he will be telling us we are in his power.”

Gale laughed nervously as the girls continued along the right hand passage. Phyllis stumbled wildly over something and shrieked madly as her exploring fingers came in contact with something cold and hard.

“What is it?” Gale demanded.

“It f-feels like a s-skull,” Phyllis murmured with difficulty.

“Don’t be silly,” Gale said, repressing a shudder. “Probably only a rock. Come along, the girls will begin to worry about us soon.”

“They would worry more if they knew we were lost in here,” Phyllis declared.

They walked on for what seemed hours, straining their eyes into the darkness for that bit of light which would mean they were near the entrance, straining their ears to catch unfamiliar sounds.

“G-Gale, do you really think we will find the way out?” Phyllis asked after a long while.

“Of course,” Gale said staunchly, with far more cheerfulness than she felt. “We can’t stay in here forever.”

“No,” Phyllis said and her voice shook uncontrollably. “Soon we would starve.”

Gale, her own nerves on edge with the darkness and their hopeless search for the opening, recognized the hysteria in her friend’s voice. But before she could remonstrate, there arose that maddening, taunting laugh.

“Gale,” Phyllis said hysterically, “I can’t stand it! I can’t! If we don’t find the entrance soon, I’ll----”

Gale shook her sternly. “Phyllis! Pull yourself together! Don’t you see, that is just what he is trying to do, get us rattled? Of course we’ll find the entrance. We’ve got to, but for goodness sake don’t go to pieces now. Wait until we get back to camp and then we’ll scream and tear our hair.”

The picture of the two of them screaming and tearing their hair was a little too much for Phyllis’ sense of humor and she laughed jerkily.

“It wouldn’t be so bad,” she said, Gale’s arm about her shoulders, “if Relentless Rudolph would stop laughing.”

“That’s a good name for him,” Gale smiled.

They stood together in the darkness, trying to fathom a way out of their predicament.

“Gale, do you suppose----” Phyllis began.

“What?” her friend encouraged.

“This sort of thing was what your uncle was thinking of when he gave us those revolvers?”

“I shouldn’t be surprised,” Gale said slowly.

“I wish I had mine now,” Phyllis wailed. “A lot of good it does us in my slicker.”

“I’ve got mine,” Gale reminded her, “but we haven’t seen anything to shoot at yet.”

“Why do you suppose he, Relentless Rudolph, is trying to scare us so?” was Phyllis’ next question.

“I haven’t the faintest idea,” Gale answered. “Unless he is trying to scare us so we will be afraid to send the police after him.”

“Not much chance,” Phyllis said indignantly. “I’d like to lead the police here, myself. If this cave didn’t give me the jitters,” she added. “Let’s get going--some place.”

Hand in hand they started off again. This passage had a more hollow sound than the others. Their footsteps, for they no longer bothered to tread silently, sounded like thunder in their ears. The ground was getting more uneven and suddenly they bumped ignominiously into the wall.

“That’s the end of that,” Phyllis said in a tired voice. “We’ll wear ourselves out before long.”

They went back the way they had come and when they came to the cross passages, chose one going in the opposite direction. Their steps were lagging, and their eyes burned from straining them to catch one glimpse of daylight.

“Phyllis! Look! The entrance!” Gale cried joyously.

“Hurray! Let’s run!” Phyllis said eagerly.

All their tiredness was gone now. They raced eagerly for the patch of light ahead of them and burst out upon a valley of green.

“I was never so glad to leave any place,” Phyllis said, sinking down beneath a tree and leaning wearily against the trunk. “Rest a couple of minutes and then we’ll go back to camp.”

“Phyllis,” Gale said slowly, gazing about them first this way and then that. “This isn’t the same place where we went in.”

“No,” Phyllis agreed thoughtfully, after looking around, “it isn’t. Don’t tell me we’re lost again! At that,” she said calmly, “I’d rather be lost out here in the open than in those underground passages.”

“Come on,” Gale said impatiently, “we can’t sit here all day. We have to find the camp.”

The sun was high overhead. It was hours since they had left their camp site. What must the others be thinking? Had Tom or Jim started out to find them?

“Maybe we could stay here and let ’em find us,” Phyllis said, relaxed and lazy.

“We can’t stay here,” Gale said decidedly. She hit upon a sudden inspiration to make her friend bestir herself. “We are too close to the cave, the bandit might pursue us,” she added smilingly.

That was enough. Phyllis jumped to her feet and started to climb over the uneven ground through the trees. At the top of the rise they saw their camp nestling beside the little creek in the valley. The subterranean passages they had been in led directly through the hill which they had started to climb earlier in the day. From where they stood now, they could see the partly hidden entrance which they had first discovered. On their way down the hillside they took particular care not to go near the mouth of the cave, lest they should see and be seen by the bank bandit.

When they returned to the camp the others greeted them with mingled exclamations of curiosity and thankfulness.

“We had about decided that you were lost,” Carol declared.

“You would have been right----” Gale began.

“Hold on!” Phyllis exclaimed. “Who is that with Jim?”

The girls saw Jim approaching the campfire where they were all gathered, and with him was the man who two days before had brought the news of the escape of the bank bandits to the K Bar O.

“Are you still hunting for the escaped robbers?” was Phyllis’ eager question the minute the two men came within hearing distance of the girls and Tom.

“Shore!” he answered promptly.

“Well,” Phyllis smiled over the sensation she knew her words would create, “we saw one of them this morning.”

“You what? Where? Are you sure it was one of them?” The questions poured from all present.

“Oh, we’re sure all right,” Phyllis said. “He scared us out of a month’s sleep. I’ve christened him Relentless Rudolph the way he followed us and laughed at us.”

“Followed you? Laughed at you?” Janet echoed. “What do you mean?”
