suggested Anne.

Grace pondered, then announced that for the present they would do nothing beyond looking for a place not only to stow their belongings, but to safeguard themselves in case of trouble. They found such a place in a cave that Hippy had discovered that morning, the opening to which was on a slight rise of ground, commanding a wide view across the valley below it.

The party investigated the cave, and, finding it suited to their needs, began to move into it. Tents, mess kits, some food and a few blankets were all that were left in the nearby camp. Hippy then a.s.sumed the duty of guarding the party, but not a sign of life did he discover, nor was there a disturbing sound to be heard. Supper was eaten in camp before dark and the cook fire then extinguished.

Grace was troubled about Tom, and, as the hours wore on, the thought that perhaps he might have come to some harm, grew upon her. She got up about midnight, and, leaving her tent, sat down on a rock, chin in hands, more nervous than she remembered ever to have been before.

Hurried footsteps aroused her to instant alertness.

"Is that you, Hippy?" called a low-pitched voice off to the right of her. It was Nora Wingate's voice. Grace had not known she was awake.

"Yes. Wake the girls, but be quiet about it. The woods are full of them."

"Of whom?" demanded Grace, getting quickly to her feet and hurrying to Hippy.

"I don't know, but I saw several men about two hundred yards from here.

They are creeping up on the camp. Hurry! Get the girls into the cave. I will keep watch here until you get safely to the cave."

It was but a few minutes later when the Overland girls filed silently from their camp and headed for the cave. Hippy, rifle in hand, halted just outside the camp and waited. He did not have long to wait. A burst of rifle fire woke the mountain echoes, but, being out of the range of fire, he merely crouched down and waited to see what the attackers would do.

In the cave, the Overland girls were peering from the opening, but, by agreement, not a shot was fired by them or by Lieutenant Wingate.

The shooting kept up briskly for several minutes, then died away, and silence settled over the scene. Hippy remained near the camp so long that the girls began to feel concerned for him. This was dispelled nearly half an hour later when they discovered him, well bent over to hide his movements, running towards them.

"Whew! They didn't do a thing to our tents. Shot them full of holes," he exclaimed. "They are going through everything and they're getting worried, judging from what I overheard. We played a neat trick on them,"

chuckled the lieutenant.

"Don't crow," advised Emma Dean. "It isn't daylight yet. I will con-centrate. I con-centrated all the time you were away, and you came back, didn't you?"

"'Con-centrate' on those ruffians and drive them away; 'con-centrate' on Tom Gray; 'con-centrate' on the Mystery Man--'con-centrate' on anybody, but for the love of Mike don't let loose any of that 'imponderable quant.i.ty' on me," begged Lieutenant Wingate.

Hippy advised the girls to lie down on their blankets and try to sleep, saying that he would keep awake and watch at the cave entrance, but none of them felt the slightest desire for sleep, especially when the rifle fire opened up again. They wondered if the attackers were shooting at shadows. Not more than a dozen shots were fired and these at intervals, after which there was no more shooting during the rest of the night.

At daybreak Hippy dozed off, first nodding to Nora to take the watch for him, which she did. The others of the party were sitting on the rocky floor of the cave leaning against the wall, also dozing. Nora, for a short time, sat watching her husband who was snoring loudly; then she got up and peered out at the reddening sky. Unthinkingly, she stepped from the cave and stood inhaling deeply of the fragrant morning air.

Nora suddenly uttered a cry and clapped a hand to her left cheek. At the same instant, it seemed, the report of a rifle woke the echoes.

Hippy, awake and on his feet in an instant, jerked Nora back into the cave, but not before a bullet had flattened itself against the rocks close to his head.

"Lie down and keep tight to the sides of the cave!" he commanded. "They know where we are now. Fine! Fine! Emma Dean could do no worse."

No more shots were fired for fully an hour, then suddenly bullets began to pour into the cave, some hitting the sides and, ricochetting, wailed on into the dark depths of the cavern, making any part of the gloomy place unsafe. The best the Overlanders could do was to keep down and lie close to the wall.

Nora had had a narrow escape from death at the first shot, though, while she had not been hit, the bullet had grazed her cheek, leaving a red mark across it.

Frequent volleys into the cave, after several hours, set the nerves of each of the Overland Riders on edge. Hippy was eager to take a hand in the fray, but the girls forbade it, advising him that he would merely be making a mark of himself, whereas it were doubtful if he could see a single one of their a.s.sailants.

"Yes, but suppose they keep us here for days?" objected Lieutenant Wingate.

"We have plenty of food," answered Anne.

"And precious little water," added Grace Harlowe. "My advice is to wait and watch. At night they are certain to come up closer to the mouth of the cave. Perhaps we may be able to get a shot at them then without exposing ourselves. Surely, if they try to enter here we can quickly drive them back."

The rest of the afternoon up to three o'clock was spent in dodging bullets. Exactly on the hour of three there came an interruption that startled every one of the cave dwellers. A rattling fire sprang up, but no bullets came their way. Hippy held up his hand for silence, and listened.

"Two gangs are at it and they must be shooting at each other. I'm going out to have a look!" cried Hippy.

"Look! Look!" cried Emma, whose curiosity had led her to follow Lieutenant Wingate.

Men were seen running down below them. On the opposite mountainside, just across the narrow valley that lay a short distance from the mouth of the cave, they saw skulking figures. Now and then one would drop to his knees and shoot at the fleeing figures in the valley.

The fleeing men in the valley, after reaching the positions they were seeking, faced their adversaries on the mountainside and began firing up at them.

"It is the feud!" cried Miss Briggs.

"That's right. I have it!" exclaimed Hippy. "This is the twenty-second of the month. The Spurgeons were going to sail into the Thompsons on the twenty-third, but Jed Thompson has beat them to it by a day, and attacked them on the twenty-second. Good generalship!"

"I call it terrible," murmured Anne Nesbit.

From their elevated position, the Overland Riders were able to observe the battle in all its details, and it was a thrilling sight. They saw men fall, but whether from bullet or from stumbling the Overlanders did not know, for, in most instances, the fallen ones soon got to their feet and joined in the fight. Now and then, however, one remained where he had dropped.

"I think the party on the mountainside is the Thompson party," announced Grace, who had been observing through her binoculars. "I am positive that I recognize Jed."

"Then the Spurgeons are on the run. Look at that, will you!" cried Lieutenant Wingate.

The supposed Spurgeons were now dashing down the valley, here and there making a stand and shooting up at their enemies, who were pouring down a hot fire on them. The shooting soon began to die down, with an occasional shot from the Thompson feudists, probably long-range shots at the fleeing figures of the Spurgeons.

"All over," announced Hippy. "We can now safely go out. I am going over to see what the camp looks like."

The girls said they too would go. They did not believe that their presence had been discovered by the Thompson fighters, but in this, however, they were mistaken. Keen eyes had espied them watching the battle from the mouth of the cave, and even then some of the Thompson party was on its way to look the Overlanders over.

Washington Washington, who, during the firing on the cave, had remained flat on his stomach on the floor, a finger in either ear, trembling with fright, now a.s.sured that he had nothing more to fear, darted on ahead, eager to get to his mule. He gained the camp a few minutes ahead of the Overland party. They saw him coming back, wide-eyed, his feet barely touching the ground as he ran.

"What is it, Laundry?" called Hippy.

Washington's lips refused to frame the words that he was trying to utter. The Overlanders started forward at a run, bringing up abruptly as they gained their camping place. Not a vestige of it, save the ashes of their cook fire, remained. Everything was gone.

"De hosses!" exploded Washington.

"They're gone!" cried Emma Dean, who, following Washington's warning, had run to the tethering place.

They were not all "gone," however. The Overland Riders found that one pony had been, shot through the head, and that the mule had shared a like fate. The other animals had disappeared, probably driven away by Bat Spurgeon and his gang of ruffians.

"Howd', folks," greeted Jed Thompson, fairly bursting into the camp.

"You-all don't know whether that critter Spurgeon has been heyeh, does ye?"

"Just cast your eagle eyes about and see if you don't think it looks as if somebody had been here, old top," answered Hippy Wingate, taking in the camp and the tethering ground with a wave of the hand.

"Our ponies are gone. Now we've got to walk all the way home," wailed Emma.
