CHAPTER V.—BLUE WOLF TRIES THE BICYCLE.

“Indians!” echoed Jack Diamond.

“Indians?” grunted Bruce Browning, astonished.

“O-oh, Lordy!” gasped Toots. “Dis am whar a nigger boy I know is gwan teh lose his scalp fo’ suah!”

“Turn!” commanded Frank—“turn to the left, and we’ll make a run to get back through the pass.”

But they were seen, and the redskins about the fire sprang to their feet with loud whoops.

At the first whoop Toots gave a howl and threw up both hands.

“Don’ yo’ shoot, good Mistar Injunses!” he shouted. “I’s jes’ a common brack nigger, an’ I ain’t no ’count nohow. Mah scalp wouldn’ be no good teh yo’ arter——”

Then he took a header off his wobbling machine and fell directly before Jack, whose bicycle struck his body, and Diamond was hurled to the ground.

“Stop, fellows!” cried Merriwell. “We mustn’t run away and leave them! Come back here!”

From his wheel he leaped to the ground in a moment, running to Diamond’s side. Grasping Jack by the arm he exclaimed:

“Up, old fellow—up and onto your wheel! We may be able to get away now! We’ll make a bluff for it.”

But it was useless, for Jack was so stunned that he could not get on his feet, though he tried to do so.

Toots was stretched at full length on the ground, praying and begging the “good Injunses” not to bother with his scalp, saying the hair was so crooked that it was “no good nohow.”

Up came the redskins on a run and surrounded the boys, Bruce and Harry having turned back.

Browning assumed a defensive attitude, muttering:

“Well, if we’re in for a scrap, I’ll try to get a crack at one or two of these homely mugs before I’m polished off.”

There were seven of the Indians, and nearly all of them carried weapons in their hands. Although they were not in war paint, they were a decidedly ugly-looking gang, and their savage little eyes denoted anything but friendliness.

“Ugh!” grunted the tallest Indian of the party, an old fellow with a scarred and wrinkled face.

“Ugh! ugh! ugh!” grunted the others.

Then they stared at the boys and their bicycles, the latter seeming a great curiosity to them.

“Well, this is a scrolly old jape—I mean a jolly old scrape!” fluttered Rattleton. “We’re in for it!”

Toots looked up, saw the Indians, uttered another wild howl, and tried to bury his head in the sand, like an ostrich.

Frank singled out the tall Indian and spoke to him.

“How do you do?” he said.

“How,” returned the Indian, with dignity.

“Unfortunately we did not know you were here, or we should not have called,” explained Merriwell.

The savage nodded; the single black feather in his hair fluttering like a pennant as he did so.

“Um know,” he said. “Um see white boy heap much surprised.”

“Jee! he can talk United States!” muttered Rattleton.

“Talk it!” said Bruce, in disgust. “He can chew it, that’s all.”

“I trust we have not disturbed you,” said Frank, calmly; “and we will leave you in your glory as soon as my friend, who fell from his wheel, is able to mount and ride.”

“No, no!” quickly declared the tall Indian; “white boy no go ’way. Injun like um heap much.”

Browning lifted his cap and felt for his scalp.

“It may be my last opportunity to examine it,” he murmured.

“But we are in a hurry, and we can’t stop with you, however much we may desire to do so,” declared Frank, glibly. “You see we are on urgent business.”

“Yes, very urgent,” agreed Rattleton. “Smoly hoke—no, holy smoke! don’t I wish I were back to New Haven, New York, any old place!”

“White boys must stop,” said the big savage. “Black Feather say so, that settle um.”

“I am afraid it does,” confessed Browning.

Diamond got upon his feet, assisted by Frank.

“Well,” he said, somewhat bitterly, “that is what we have come to by failing to heed the warning we received!”

“Don’t go to croaking!” snapped Rattleton. “These Indians are peaceable. They are not on the war path.”

“But they are off the reservation,” said Frank, in a low tone; “and that is bad. They have us foul, and there is no telling what they may take a notion to do.”

“It’s pretty sure they’ll take a notion to do us,” sighed Harry.

The tall Indian, who had given his name as Black Feather, professed great friendliness, and, when the boys told him they had been looking for the water-hole, he said:

“Um water-hole dare by fire. Good water, heap much of it. Come, have all water um want.”

“Well, that is an inducement,” confessed Browning. “We may be able to get a square drink before we are scalped.”

It was with no small difficulty that Toots was forced to get up, and, after he was on his feet, he would look at first one Indian and then dodge, and look at another, each time gurgling:

“O-oh, Lord!”

And so, surrounded by the Indians, the boys moved over to the fire, which was near the water-hole, as Black Feather had declared.

“Well, we’ll all drink,” said Frank, as he produced his pocket cup and proceeded to fill it. “Here, fellows, take turns.”

While they were doing so the Indians were examining their bicycles with great curiosity. It was plain the savages had never before seen anything of the kind, and they were filled with astonishment and mystification. They grunted and jabbered, and then one of them decided to get on and try one of the wheels.

It happened that this one was the smallest, shortest-legged redskin of the lot, and he selected the machine with the highest frame.

“Ugh!” he grunted. “White boy ride two-wheel hoss, Injun him ride two-wheel hoss heap same. Watch Blue Wolf.”

“Yes,” said Browning, softly, nudging Merriwell in the ribs with his elbow, “watch Blue Wolf, and you will see him smash my bicycle. I sincerely hope he will break his confounded head at the same time!”

“White boy show Injun how um git on,” ordered Blue Wolf.

“Go ahead, Bruce,” directed Frank.

“Oh, thunder!” groaned the big fellow. “I’m so tired!”

But he was forced to show the Indians how he mounted the wheel, which he did, being dragged off almost as soon as he got astride the saddle.

“Ugh!” grunted Blue Wolf, with great satisfaction. “Um heap much easy. Watch Blue Wolf.”

“Yes, watch Blue Wolf!” repeated Browning. “It will be good as a circus! Oh, my poor bicycle!”

With no small difficulty the little Indian steadied the wheel, reaching forward to grasp the handlebars while standing behind it. The first time he lifted his foot to place it on the step he lost his balance and fell over with the machine.

The other Indians grunted, and Blue Wolf got up, saying something in his own language that seemed to make the atmosphere warmer than it was before.

The bicycle was lifted and held for the little Indian to make another trial. He looked as if he longed to kick it into a thousand pieces, but braced up, placed his foot on the step and made a wild leap for the saddle. He missed the saddle, struck astride the frame just back of the handlebars, uttered a wild howl of dismay, and went down in hopeless entanglement with the unfortunate machine.

“Wow!” howled Blue Wolf.

“Oh, my poor bicycle!” groaned Browning, once more.

The fallen redman kicked the bicycle into the air, but it promptly came down astride his neck and drove his nose into the dirt.

“Ugh!” grunted the watching Indians, solemnly.

“Whoop!” roared Blue Wolf, spitting out a mouthful of dirt.

Then he made another frantic attempt to cast the machine off, but it persisted in sticking to him in a wonderful manner. One of his arms was thrust through the spokes of the forward wheel to the shoulder, and as he tried to yank it out, the rear wheel spun around and one of the pedals gave him a terrific thump on the top of the head.

“Yah!” snarled the unlucky Indian.

“Two-wheel hoss kick a heap,” observed Black Feather.

Blue Wolf tried to struggle to his feet, but he was so entangled with the bicycle that it seemed to fling him down with astonishing violence.

Then as the noble red man kicked, and squirmed, and struggled, the bicycle danced and pranced upon his prostrate body like a thing of life.

“O-o-oh!” wailed Blue Wolf, in pain and fear.

Toots suddenly forgot his fears, and holding onto his side, he doubled up with a wild burst of “coon” laughter.

“Oh, land ob watermillions!” he shouted. “Dat bisuckle am knockin’ de stuffin’ out ob Mistah Injun! Yah! yah! yah! Lordy! lordy! ’Scuse meh, but I has ter laff if it costs me all de wool on mah haid!”

Browning folded his arms, a look of intense satisfaction on his face as he observed:

“I have made a discovery that will be worth millions of dollars to the government of the United States. Now I know a swift and sure way of settling the Indian question. Provide every Indian in the country with a bicycle, and there will be no Indians left in a week or two.”

“Gamlet’s host—I mean Hamlet’s ghost!” chuckled Rattleton, holding his hand over his mouth to keep from shrieking with laughter. “I never saw anything like that before!”

Merriwell sprang forward and assisted Blue Wolf in untangling himself from the wheel, fearing the bicycle would be utterly ruined.

The little Indian was badly done up. His face was cut and bleeding in several places, and he was covered with dirt. With some difficulty he got upon his feet, and then he backed away from the bicycle, at which he glared with an expression of great fear on his countenance.

“Heap bad medicine!” he observed.

It seemed that the other Indians were really amused, although they remained solemn and impassive.

“Give me hatchet!” Blue Wolf suddenly snarled. “Heap fix two-wheel hoss!”

He would have made a rush for the offending wheel, but Frank held up a hand warningly, crying:

“Beware, Blue Wolf! It is in truth bad medicine, and it will put a curse upon you if you do it harm. Your squaw will die of hunger before another moon, your children shall make food for the coyotes, and your bones shall bleach on the desert! Beware!”

Blue Wolf paused, dismay written on his face. He longed to smash the bicycle, but he was convinced that it was really “bad medicine,” and he was afraid to injure it.

“Say, that is great, old man!” enthusiastically whispered Rattleton in Merriwell’s ear. “Keep it up.”

“Blue Wolf not hurt two-wheel hoss,” declared Black Feather, who seemed to be the chief of the little band. “Want to see white boy ride.”

“Do you mean that you want me to ride?” asked Frank.

“Ugh!”

“All right,” said Frank. “I’ll show you how it is done.”

Then he motioned for the savages to stand aside.

“No try to run ’way,” warned Black Feather. “Injun shoot um.”

“All right, your royal jiblets. If I try to run away you may take a pop at me.”

CHAPTER VI.—TRICK RIDING.

The Indians made room for Frank to mount and ride.

Standing beside the wheel Frank sprang into the saddle without using the step, caught the pedals and started.

The savages gave utterance to a grunt of wonder and admiration.

Frank had practiced trick riding, and he now proposed to exhibit his skill, feeling that it might be a good scheme to astonish the savages.

He started the bicycle into a circle, round which he rode with the greatest ease, and then of a sudden he passed one leg over the frame, and stood up on one of the pedals, which he kept in motion at the same time.

The Indians nodded and looked pleased.

Then Frank began to step cross-legged from pedal to pedal, passing his feet over the cross bar of the frame and keeping the wheel in motion all the time.

A moment later he whirled about, and with his face toward the rear, continued to pedal the bicycle ahead the same as if he had been seated in the usual manner on the saddle.

“Heap good!” observed Black Feather.

Then, like a cat Merriwell wheeled about, lifted his feet over the handlebars to which he clung, slipped down till he hung over the forward wheel, placed his feet on the pedals, and rode in that manner. This made it look as though he were dragging the bicycle along behind him.

There was a stir among the Indians, and they looked at each other.

Without stopping the bicycle, Frank swung back over the handlebars to the saddle. Having reached this position, he stopped suddenly, turning the forward wheel at an angle, sitting there and gracefully balancing on the stationary machine.

“Heap much good!” declared Black Feather, growing enthusiastic.

“Oh, those little things are dead easy,” assured Frank, with a laugh. “Do you really desire to see me do something that is worth doing?”

“What more white boy can do?”

“Several things, but I’ll have to make a larger circle.”

It was growing dark swiftly now, the sun being down and the shadows of the mountains lying dark and gloomy in the valleys.

“Go ’head,” directed Black Feather.

Frank started the bicycle in motion, and then, with it going at good speed, he swung down on one side and slowly but neatly crept through the frame, coming up on the other side and regaining the saddle without stopping.

“Paleface boy great medicine!” said Black Feather.

“Ugh!” grunted all the Indians but Blue Wolf.

The little savage was looking on in a sullen, wondering way, astonished and angered to think the white boy could do all those things, while he had been unable to mount the two-wheeled horse.

“How do you like that, Black Feather?” asked Frank, cheerfully.

“Much big!” confessed the chief. “Do some more.”

“All right. Catch onto this.”

Then away Frank sped, lifting the forward wheel from the ground and letting it hang suspended in the air, while he rode along on the rear wheel.

“Merry is working hard enough,” said Rattleton. “I never knew he could do so many tricks.”

“There are lots of things about that fellow that none of us know anything about,” asserted Browning, who was no less surprised, although he did not show it.

“He is a fool to work so hard to please these wretched savages!” muttered Diamond.

“Now, don’t you take Frank Merriwell for a fool in anything!” came swiftly from Harry. “I never knew him to make a fool of himself in all my life, and I have seen a good deal of him.”

“Well, why is he cutting up all those monkey tricks? What will it amount to when it is all over?”

“Wait and see.”

“The Indians will treat us just the same as if he had not done those things.”

“Perhaps so.”

“Of course they will!”

“Now, Black Feather, old jiblets,” cried Frank, in his merriest manner, “I am going to do something else. Get onto this.”

Sending the bicycle along at high speed Frank lay over the handlebars and swung his feet into the air till he held himself suspended in that manner, head down and feet up.

The Indians were more pleased and astonished than ever.

“Oh, it’s all in knowing how!” laughed Frank, as he gracefully and lightly dropped back to the saddle.

Again the Indians grunted.

“Now, Black Feather, old chappie,” said Frank, “I am going to do the greatest trick of all. I’ll have to get a big start and have lots of room. Watch me close.”

Away he went, bending over the handlebars and sending the bicycle flying over the ground. He acted as if he intended to make a big circle, but suddenly turned and rode straight toward the pass by which they had entered the basin. Before the Indians could realize his intention, he was almost out of sight in the darkness of the young night.

Howls of rage and dismay broke from the redmen. They shouted after the boy, but he kept right on, quickly disappearing from view.

“There,” sighed Browning, with satisfaction, “I told you he was not doing all that work for nothing, fellows.”

“He’s done gone an’ lef us!” wailed Toots.

“That’s what he has!” grated Diamond—“left us to the mercy of these miserable redskins! That’s a fine trick!”

“Oh, will you ever get over it?” rasped Rattleton. “Why shouldn’t he? He had his chance, and he’d been a fool not to skin out!”

“I thought he would stand by us in such a scrape as this.”

“What you thought doesn’t cut any ice. He’ll come back.”

“After we are murdered.”

Rattleton would have said something more, but the Indians, who had been holding an excited conversation, suddenly grasped the four remaining lads in a threatening manner.

“Oh, mah goodness!” palpitated Toots. “Heah is whar I’s gwan teh lose mah wool! It am feelin’ po’erful loose already!”

Browning was on the point of launching out with his heavy fists and making as good battle of it as he could when he heard Black Feather say:

“No hurt white boys. Make um keep still, so um not run ’way off like odder white boy. That am all.”

“I’ll take chances on it,” muttered Bruce, giving up quietly.

The four lads were forced to sit on the ground, and some of the savages squatted near. The fire was replenished, and the Indians seemed to hold a council.

“Deciding how they will kill us,” said Diamond, gloomily.

“Nothing of the sort,” declared Rattleton. “See them making motions toward the bicycles. They are talking about the wonderful two-wheeled horses.”

“Gracious!” gasped Toots; “dat meks mah hair feel easier!”

Browning held a hand on his stomach in a pathetic manner.

“Oh, my!” he murmured. “How vacant and lonely my interior department seems to be! Methinks I could dine.”

“The hard bread and jerked beef,” whispered Jack. “It is in the carriers attached to the wheels.”

“Yes, and we had better let it remain there.”

“Why?”

“These Indians look hungry, too.”

“You think——”

“I do. They will take it away from us and eat it if we bring it out. That would leave us in a bad fix.”

“But they can get it out of the carriers.”

“They can, but they won’t.”

“Why not?”

“They are afraid of those bicycles—so afraid that they will not go near them. Therefore our hard bread and jerked beef is safe as long as we let it remain where it is.”

Harry agreed with Bruce, and they decided not to touch the food in the carriers; but all were thirsty again, and they expressed a desire to have another drink from the water-hole.

To this the Indians did not object, and they took turns at drinking, although the water did not taste nearly as sweet as it had the first time.

Having satisfied themselves in this manner they sat down on the ground once more, being compelled to do so by the redskins, who were watching them closely.

“They have us in a bad position in case they take a notion to crack us over the head,” said Harry. “We wouldn’t get a show.”

“Mah gracious!” gurgled Toots, holding fast to his scalp with both hands. “We’s gwan teh git it fo’ suah, chilluns! De fus’ fing we know we won’t no nuffin’!”

“We must get out of this somehow,” muttered Bruce.

“That’s right,” nodded Jack. “Merriwell has taken care of himself, and left us to take care of ourselves.”

He spoke in a manner that showed he felt that Frank had done them a great wrong.

“It’s a good thing he got away as he did,” asserted Harry. “Now we know we have a friend who is not a captive like ourselves, and we know he knows the fix we are in. You may be sure he will do what he can for us.”

“He’ll do what he can for himself. How can he do anything for us?”

“He’ll find a way.”

“I doubt it.”

“You have become a great doubter and kicker of late, Diamond. It is certain the loss of that Mormon girl who married the other fellow has soured you, for you were not this way before. Why don’t you try to forget her?”

“I wish you might forget her! You make me sick talking about her so much! I don’t like it at all!”

“If you don’t like it lump it.”

Jack and Harry glared at each other as if they were on the point of coming to blows, and this gave Browning an idea. He saw the Indians had noticed there was a disagreement between the boys, and he leaned forward, saying in a low tone:

“Keep at it, fellows—keep at it! I have a scheme. Pretend you are fighting, and they will let you get on your feet. When I cry ready we’ll all make a jump for our wheels, catch them up, place them in the form of a square, and stand within the square. The redskins are afraid of the wheels—think them ‘bad medicine.’ They won’t dare touch us.”

Browning had made his idea clear with surprising swiftness, and the other boys were astonished, for they had come to believe that the big fellow never had an original idea in his head.

Both Jack and Harry were taken by the scheme, and Diamond quickly said:

“It’s a go. Keep on with the quarrel, Rattleton.”

Harry did so, and in a very few seconds they were at it in a manner that seemed intensely in earnest. Their voices rose higher and higher, and they scowled fiercely, flourishing their clinched hands in the air and shaking them under each other’s nose.

Browning got into the game by making a bluff at stopping the quarrel, which seemed to be quite ineffectual. He seemed to try to force himself between them, but Rattleton hit him a hard crack on the jaw with his fist, with which he was threatening Diamond.

“Scissors!” gurgled Bruce, as he keeled over on his back, holding both hands to his jaw. “What do you take me for—a punching bag?”

“You have received what peacemakers usually get,” said Harry, as he continued to threaten Diamond.

The Indians looked on complacently, their appearance seeming to indicate that they were mildly interested, but did not care a continental if the two white boys hammered each other.

Jack scrambled to his feet and dared Harry to get up. Harry declared he would not take a dare, and he got up. Then Bruce and Toots lost no time in doing likewise, and, just when it seemed that the apparently angry lads were going to begin hammering each other Browning cried:

“Ready!”

Immediately the boys made a leap for the bicycles, caught them up, formed a square with them, and stood behind the machines, like soldiers within a fort.

The Indians uttered shouts of astonishment, and the four boys found themselves looking into the muzzles of the guns in the hands of the savages.

“What white boys mean to do?” harshly demanded Black Feather. “No can run away.”

“Heap shoot um!” howled Blue Wolf, who seemed eager to slaughter the captives. “Then no can run away.”

“Hold on!” ordered Browning, with a calm wave of his hand. “We want to parley.”

“Want to pow-wow?” asked Black Feather.

“That’s it.”

“No pow-wow with white boys. White boys Injuns’ prisoners. No pow-wow with prisoners.”

“No!” shouted Blue Wolf. “Shoot um! shoot um!”

“Land ob massy!” gurgled Toots. “Dey am gwan teh shoot!”

“Black Feather,” said Browning, with assumed assurance and dignity, “it will not be a healthy thing for your men to shoot us.”

“How? how?”

“Do you see that we are protected by the ‘bad medicine’ machines? If you were to do us harm now, these machines would utterly destroy you and every one of your party. The moment you fired at us these machines would be like so many demons let loose, and as they are not made of flesh and blood, they could not be harmed. Not one of your party could escape them.”

The light of the fire showed that the Indians looked at each other with mingled incredulity and fear.

“Wow!” muttered Rattleton. “Is this Browning I hear? How did you happen to think of such a bluff?”

“Have to think in a case like this,” returned the big fellow, guardedly. “I think only when it is absolutely necessary. This is one of those occasions.”

The Indians got together and held a consultation.

“Can’t we make a run for it now?” asked Diamond, eagerly.

“We can,” nodded Bruce, “but we won’t run far. They’d be able to drop us before we could get out of the light of the fire.”

“What can we do?”

“Why, we’ll have to——”

Browning was interrupted by a clatter of hoofs, which caused him to turn toward the East. The Indians heard the sound, and they turned also.

Then wild yells of terror rent the air.

CHAPTER VII.—ESCAPE.

Coming through the darkness at a mad gallop was what seemed to be the gleaming skeleton of a horse. The ribs, the bones of the neck, legs and head, all showed plainly, glowing with a white light.

And on the back of the horse, which had sheered to the north and was passing the fire, sat what seemed to be the skeleton of a human being, the bones gleaming the same as those of the horse.

It was almost an astonishing and awe-inspiring spectacle, and it frightened the Indians greatly.

“Howugh—owugh—owugh!” wailed Black Feather, dismally.

Then the savages dropped on their faces, covering their eyes, so they could not see the skeleton horseman.

Almost at the same moment as the horseman was passing the spot the ghastly appearing thing seemed to give a sudden swing about and completely disappear.

“Poly hoker!” gasped Rattleton. “It’s gone!”

“That’s right!” palpitated Diamond—“vanished in a moment!”

“Oh, mah soul—mah soul!” wailed Toots. “Dat sholy am de ol’ debbil hisse’f, chilluns! When we see it next it’s gwan teh hab one ob us fo sho!”

“Hark!” commanded Browning.

The beat of the horse’s feet could be distinctly heard, but the creature had turned about and was going back toward the pass through the bluffs.

Chucker-chucker-chuck! chucker-chucker-chuck! chucker-chucker-chuck! came the ghostly sounds of the galloping horse.

“It’s turned about!” gasped Harry, in astonishment.

“It’s going!” fluttered Jack.

“And we’d better be going, too!” put in Browning.

Then with a familiar whirring sound something came flying toward them through the darkness, causing Toots to utter a wild shriek of terror.

Into the light of the camp-fire flashed a boy who was mounted on a bicycle, and they saw it was Frank Merriwell.

“Away!” he hissed, as he flew past them. “Make straight for the pass by which we entered this pocket. I will join you.”

Then he was gone.

Browning gave Toots a sharp shake, fiercely whispering:

“Mount your wheel and keep with us if you want to save your scalp! If you don’t you will be left behind.”

Then the boys leaped upon their bicycles and were away in a moment, before the prostrate Indians had recovered from the shock of terror given them by the appearance of the skeleton horse and rider.

For the time Bruce Browning took the lead, and the others followed him. Toots had heeded the big fellow’s warning words, and he was not left behind.

Barely had they passed beyond the range of the firelight and disappeared in the darkness when wild yells of anger came from behind them, and they knew the Indians had discovered they were gone.

“Bend low! bend low!” hissed Diamond. “They may take a fancy to shoot after us! Stoop, fellows!”

Stoop they did, bending low over the handlebars of their bicycles.

Bang! bang! bang!

The Indians fired several shots, and they heard some of the bullets whistle past, but they were not hit.

“Well, that’s what I call luck!” muttered the young Virginian.

“What do you call luck?” asked Rattleton.

“The appearance of that skeleton horse and rider in time to scare the Indians and give us a chance to get away.”

“Oh!” said Harry, sarcastically, “I didn’t know but it was Merry’s return. I told you he would not desert us.”

“I wonder how he happened to come back just then?”

“He came back because he was watching for an opportunity to help us, and he saw we had a splendid chance to get away while the redskins were scared by the appearance of the horse and rider. You ought to know him well enough to know he is not the fellow to desert his friends in a scrape like this.”

Diamond was silent.

“I wonder where Frank is?” said Browning. “He said he would join us, and he is——”

“Right here, old man,” said a cheerful voice, as a flying bicycle brought Merriwell out of the darkness to Browning’s side. “This way, fellows! We’ll hit the pass and get out of here as soon as we can.”

“Lawd bress yeh, Marser Frank!” cried Toots, joyfully. “I didn’t know’s I’d see yeh no mo’, boy!”

“I hope you didn’t think I had left you for good?”

“No, sar!” declared the colored boy. “I done knows yeh better dan dat, sar! I knowed yeh’d come back, but I was afeared yeh’d come back too late, sar. Dem Injunses was gittin’ po’erful anxious fo’ dis yar wool ob mine—yes, sar!”

“Well, I am glad to know you thought I would not desert you. I don’t want any of my friends to think I would go back on them in the hour of need.”

Diamond was silent.

The pass was found without difficulty, and they went speeding through it.

“How did you happen to turn up just then, Frank?” asked Harry.

“I was waiting for a chance to come to you, and I saw the chance when that horse and rider frightened the Indians.”

“The horse and rider—where are they?” asked Browning.

“Gone through the pass ahead of us.”

“Mah gracious!” exclaimed the colored boy. “What if dat ol’ debbil teks a noshun teh wait fu’ us?”

“What sort of ghost business was it, anyway?” questioned Rattleton. “It seemed to be a skeleton horse and a skeleton rider, and it disappeared in a twinkling. I will admit this skeleton business is beginning to work on my nerves.”

“It is rather creepish,” laughed Frank; “but I do not think it is very dangerous.”

“All the same, you do not attempt to explain the mystery.”

“Not now.”

“Not now? Can you later?”

“Perhaps so.”

“It is plain he knows no more about it than the rest of us,” said Diamond. “As for me, I am getting sick of seeking vanishing lakes and vanishing skeletons. If I get out of this part of the country alive, you’ll never catch me here again.”

“Meh, too!” exclaimed Toots.

“Well, I don’t know as any of us will care to revisit it,” laughed Frank. “Anyway, we have been very lucky in escaping from those Indians. That you can’t deny.”

“You fooled them easily,” said Rattleton.

“Yes, and they did not even take a shot at me, which was a surprise. I expected they would pop away a few times.”

“What are we going to do after we get out on the open desert again?” asked Jack. “It seems to me we’ll be as bad off as ever.”

“We’ll have to go around the range to the south, or wait for the Indians to get away from that water-hole, so we can go through the mountains as we originally intended.”

“The Indians may not go away.”

“I rather think they have been scared so they’ll not hang around there long. I don’t fancy they’ll be anywhere in the vicinity by morning.”

“If they are gone——”

“We’ll be all right, providing we can make our hard bread and dried beef hold out till we can reach one of the small railroad towns.”

“How far away is the railroad?”

“Not much over fifty miles.”

“That is easy!” declared Rattleton. “We can make it on a spurt!”

As they reached the eastern opening of the pass their attention was attracted by a bright light that seemed to shine out from the very niche where they had found the jewel-decorated skeleton.

“What does that mean?” exclaimed Jack, in astonishment.

“Land ob wartermillions!” gasped Toots. “It am de debbil’s light fo’ suah, chilluns! Don’ yeh go near it!”

“By Jove!” cried Frank. “That is worth investigating! Come on, fellows!”

He headed straight toward the light, and as they came near the niche they saw the bejeweled skeleton was again seated as they had seen it in the first place, and a bright flood of light was shining upon it from some mysterious place.

“It’s back!” exclaimed Harry, in astonishment.

“Sure enough!” said Frank. “It is on deck again.”

“I tells yeh to keep away from dat skillerton!” shouted Toots. “Hit am gwan teh grab yo’ this time if yo’ gits near hit!”

“We’ll take chances on that,” declared Frank. “This time we won’t give it time to get away, but we’ll go right up and examine it.”

“That’s what we will!” agreed Harry.

But even as he spoke, the light disappeared, and this made it impossible for them to see anything up there in that dark nook.

“Ha! ha! ha!”

Again they heard the mocking laughter, smothered, hollow and ghostly in sound.

“Somebody is having lots of fun with us,” said Frank, as he leaped from his wheel. “It may be a good joke, but I fail to see where the ‘ha, ha,’ comes in.”

“Is the skeleton gone?”

“I don’t know, but I’ll mighty soon find out.”

Without hesitation he swung himself up to the niche in the rocks, and Rattleton followed, determined that Frank should not go alone into danger.

Harry afterward confessed that he was shivering all over when he climbed up there in the darkness, but his fear did not keep him from sticking to Merry.

A cry broke from Frank’s lips.

“What is it?” called Browning, from below.

“By the eternal skies, it’s gone again!”

“Didn’t I tole yeh!” cried Toots, from a distance. “Come erway from dar, Marser Frank! If yo’ don’, yo’s gwan teh be grabbed!”

“It is gone!” agreed Rattleton. “This beats the Old Nick!”

Again they heard that mocking laugh, which seemed to come down from some point above their heads.

“Wooh!” shivered Harry. “That sounds pleasant!”

“Hang it all!” exclaimed Frank, in a voice that indicated chagrin. “I don’t like to be made fun of this way! If we don’t solve this mystery before we go away I shall always regret it.”

“Beware!”

It was the same voice that had uttered the warning when they were riding into the pass, and now, in the darkness of night, it sounded even more dismal and uncanny than before.

“Come out and show yourself,” called Frank.

For some time the boys remained there, but they were forced to abandon the task of solving the mystery that night. Frank descended to the ground with no small reluctance, and Harry kept close to him. They mounted their wheels and rode away once more, fully expecting to hear the mocking laughter, or the ghostly voice calling after them. In this, however, they were disappointed, as nothing of the kind happened.

After they had ridden some distance, Frank proposed that they halt for the night.

“We are in for an open-air camp to-night,” he said. “It is something we did not expect, but it can’t be helped, and as the night is not cold I think we can get along all right. We need rest, too.”

“That’s right,” agreed Bruce. “I feel as if I need about a week of steady resting, but I don’t care to take it here.”

“How about the Indians?” asked Jack. “We are not very far from them, and they might find us.”

“I scarcely think there is any danger of that.”

“Why not?”

“Those redskins were so badly frightened that they’ll not go hunting after white boys to-night. It is more likely they will skin out and make for the Shoshone Reservation, on which they must belong.”

“But what if they should happen to follow us?” Jack persisted.

“We must take turns at standing guard to-night, and the guard should be able to give us warning of danger in time for us to mount our wheels and get away.”

It was plain that Diamond was not in favor of stopping there, but he said no more.

Fortunately the night was warm, so they suffered no discomfort by sleeping thus. No dew fell out there on the desert.

It was arranged that Diamond should stand guard first, while Frank came second, with Toots for the last guard toward morning.

They ate some of the hard bread and jerked beef and then threw themselves down, with their bicycles near at hand, so they could spring up and mount in a hurry if necessary.

Browning was the first to stretch himself on the ground, and he was snoring almost immediately. The others soon fell asleep.

The rim of a round, red moon was showing away to the eastward when Jack awoke Frank.

“How is it?” Merriwell asked. “Have you heard or seen anything suspicious?”

“Not a thing,” was the reply. “All is still as death out here—far too still. I don’t like it.”

“Well, it is not real jolly,” confessed Frank, with a light laugh; “but I don’t think we need to be worried about visitors; and that is one good thing.”

Jack was fast asleep in a short time.

Morning came, and Toots was the first to awaken. Dawn was breaking in the east as he sat up, rubbing his eyes and muttering:

“Good land! dat am de hardes’ spring mattrus dis coon ebber snoozed on—yes, sar! Nebber struck nuffin’ lek dat befo’.”

Then he looked around in some surprise.

“Gracious sakes!” he continued. “Whar am de hotel? It done moved away in de night an’ lef’ us.”

It was some time before he realized that they had not put up at a hotel the night before.

“Reckum dis is whar we stopped las’ night,” he finally said. “I ’membah ’bout dat now. We was ter tek turns watchin’. I ain’t took no turn at all, an’ it’s wamnin’. He! he! he! Guess de chap dat was ter wake me fell asleep hisself an’ clean fergot it. Dat meks meh ’bout so much sleep ahaid ob de game.”

He was feeling good over this when he noticed that three forms were stretched on the ground near at hand, instead of four.

“Whar am de odder one?” he muttered. “One ob dem boys am gone fo’ suah. Land ob wartermillions! What do hit mean? Dar am Dimun, an’ dar am Rattletum, an’ dar am Brownin’, but whar—whar am Marser Frank?”

In a moment he was filled with alarm, and he lost no time in grasping Harry’s shoulder and giving it a shake, while he cried:

“Wek up heah, yo’ sleepy haid—wek up, I tells yeh! Dar’s suffin’ wrong heah, ur I’s a fool nigger!”

“Muts the whatter?” mumbled Rattleton, sleepily. “Can’t you let a fellow sleep a minute? It isn’t my turn yet.”

“Yoah turn!” shouted Toots. “Wek up, yo’ fool! It’s done come mawnin’, an’ dar’s suffin’ happened.”

“Eh?” grunted Harry, starting up and rubbing his eyes. “Why the moon is just rising.”

“Moon!” snorted the colored boy. “Dat’s de sun comin’ up! An’ I don’t beliebe yo’ took yoah turn keepin’ watch.”

Browning grunted and rolled over, flinging out one arm and giving Toots a crack on the neck that keeled him over on the ground.

“Landy goodness!” squealed the darky, grasping his neck with both hands. “What yo’ tryin’ ter do, boy? Want ter coon? Nebber seen such car’less pusson, sar!”

“Oh, shut up your racket!” growled the big college lad. “I’m not half rested yet. Call me when breakfast is ready.”

“Yo’ll done git yeh own breakfas’ dis mawnin’, sar; but befo’ dar’s any breakfas’ we’s gwan ter know what has become of Marser Frank. He’s gone.”

“Gone?” replied Bruce, sitting up with remarkable quickness.

“Gone?” ejaculated Harry, popping up as if he were worked by springs.

“Gone where?” asked Diamond, also sitting up and staring around.

“Dat’s jes’ what I wants ter know, chilluns,” declared Toots. “Dat boy ain’t heah, an’ I’s po’erful feared de old skillerton debbil has cotched him.”

“Why—why,” said Jack, “I woke him and he took my place.”

“But nobody roused me,” declared Rattleton.

“Nor me,” asserted Browning.

“Git up, chilluns—git up!” squealed Toots, excitedly. “We’s gotter find dat boy in a hurry! ’Spect he’s in a berry bad scrape!”

CHAPTER VIII.—THE MYSTERY EXPLAINED.

By this time the boys were fully aroused. An investigation showed that Merriwell’s wheel was gone.

“Didn’t I tole yeh old debbil skillerton would done cotch some ob us!” cried Toots, in great distress.

“I hardly understand what the skeleton could have wanted with Merry’s wheel,” observed Browning.

“G’way dar, boy! Didn’ de skillerton ride a hawse!”

“And you think it is an up-to-date skeleton that has decided to ride a bicycle hereafter. In that case, I congratulate Mr. Skeleton on his good sense.”

“It must be that Frank has gone on a ride without saying anything to us,” said Jack. “I do not see any other way of explaining it.”

“But why should he do such a thing?” asked Rattleton.

“That is where you stick me.”

Browning slowly shook his head.

“It is remarkable that he should do such a thing without saying anything to us,” declared the big fellow.

“And he must have taken that ride in the night,” said Jack.

“While he should have been on guard,” added Harry.

The boys stood looking at each other in sober dismay.

“It isn’t possible that Merry could have gone daffy,” muttered Rattleton. “He is too well balanced for that.”

“I don’t know,” came gloomily from Diamond. “This dismal, burning desert is enough to turn the brain of any fellow.”

“Yah!” cried Toots. “Don’ yeh git no noshun dat boy ebber had his brain turned! It am de weak brains dat git turned dat way. His brain was all right, but I jes’ know fo’ suah dat he hab been cotched.”

“And I suppose you want to run away as soon as possible before you are ‘cotched?’”

Then the colored boy surprised them all by saying:

“No, sar, I don’ want teh go ’way till we knows what hab become ob Marser Frank. Dat boy alwus stick by his frien’s, an’ dis coon am reddy teh stick by him, even if he do git cotched.”

“Good stuff, Toots!” cried Rattleton, approvingly. “You are all right! If anything has happened to Frank we’ll know what it is or leave our bones here.”

The boys were worried. They hurriedly talked over the remarkable disappearance, trying to arrive at an understanding of its meaning.

At length it was agreed that Frank might have gone back to try to solve the mystery of the skeleton, and then they decided that two of the party should remain where they had made their night bivouac, while the other two proceeded to search for Merriwell.

Diamond insisted on being one of the searchers, and Rattleton was determined to be the other, so Browning and Toots were left behind.

The boys mounted their wheels and rode back toward the pass through the bluffs.

Diamond was downcast again.

“Everything is going against us,” he declared. “There is fate in it. I am afraid we’ll not get out of this wretched desert.”

“Oh, you’re unwell, that’s what’s the matter with you!” declared Harry, scornfully. “I’ll be glad when you are yourself again.”

“That’s all right,” muttered Diamond. “You are too thoughtless, that’s what’s the matter with you.”

They approached the spot where the mysterious skeleton had been seen, and both were watching for the niche in the rocks.

Suddenly they were startled by hearing a wild cry from far above their heads, and looking upward they saw Frank Merriwell running along the very brink of the cliff, but limping badly, as if he were lame.

But what astonished and startled them the most was to see a strange-looking, bare-headed man, who was in close pursuit of Frank. Above his head the man wildly flourished a gleaming, long-bladed knife, while he uttered loud cries of rage.

“Smoly hoke!” cried Harry. “Will you look at that!”

Diamond suddenly grew intensely excited.

“What can we do?—what can we do?” he exclaimed. “Frank is hurt! That creature is running him down! He will murder him!”

“If Merry had a pistol he would be all right.”

“But he hasn’t! We must do something, Harry—we must!”

“Neither of us has a gun.”

“No, but——”

“We can’t get up there.”

“But we must do something!”

“We can’t!”

Jack grew more and more frantic. He leaped from his wheel and seemed to be looking for some place to try to scale the face of the bluff.

“Oh, if I could get up there!” he groaned. “I’d show Frank that I was ready to stand by him! I’d fight that man barehanded!”

And Rattleton did not doubt it, for he well knew how hot-blooded Diamond was, and the young Virginian had never failed to fight when the occasion arose. He would not shirk any kind of an encounter.

Merriwell saw them and shouted something to them, but they could not understand what he said.

“Turn! turn!” screamed Jack. “You must fight that man, or he will stab you in the back! He is going to strike you!”

Frank seemed to hear and comprehend, for he suddenly wheeled about and made a stand. In a moment the man with the knife had rushed upon him and struck with that gleaming blade.

A groan escaped Jack’s lips as he saw that blow, but it turned to a gasp of relief when Frank stopped it by catching the man’s wrist.

“Give it to him! Give it to him!” shrieked Diamond, dancing around in a wild frenzy of anxiety and fear.

Then the boys below witnessed a terrific struggle on the heights above them.

The man seemed mad with a desire to plunge the knife into Frank, and it was plain that Merriwell did not wish to harm the unknown, but was trying to disarm him.

“What folly! what folly!” panted Diamond. “He’ll get his hand free and stab Merry sure! Beat him down, Frank—beat him down!”

Once Frank slipped and fell to his knees. A fierce yell of triumph broke from the man, and it seemed that he would succeed in using the knife at last.

With a groan of anguish Diamond covered his eyes that he might not witness the death of the friend he loved. For Jack Diamond did love Frank Merriwell, for all that he had complained against him of late.

A cry of relief from Rattleton caused Jack to look up again, and he saw Frank had regained his feet and was continuing the battle.

And now the man fought with a fury that was nerve thrilling to witness. His movements were swift and savage, and he tried again and again to draw the knife across Frank’s throat.

Jack and Harry scarcely breathed until, with a display of strength and skill, Frank disarmed his assailant by giving his arm a wrench, causing the knife to fly through the air and fall over the edge of the cliff.

Down to the ground below rattled the knife, and then Diamond said:

“Now Frank will be able to handle the fellow!”

But, flinging his arms about the boy, the man made a mad effort to spring over the brink. For some seconds, locked thus in each other’s arms, man and boy tottered on the very verge, and then they swayed back.

Frank broke the hold of the man, striking him a heavy blow a second later. The man reeled and dropped on the edge of the precipice. He scrambled up hastily, but a great slice of rock cleaved off beneath his feet and went plunging downward.

Then the watching boys saw the unknown tottering on the brink, wildly waving his arms in an endeavor to regain his balance. Frank sprang forward to aid him.

Too late!

With a wild scream of despair, the strange man toppled over and whirled downward to his death.

Frank climbed down.

“It’s all up with him, poor fellow,” said he, as he stood near the body of the unknown man, looking down at the face that was white and calm and peaceful in death.

“Who is he?” asked Harry.

“What is he?” asked Jack.

“I am afraid those questions cannot be answered,” confessed Frank. “That he was a raving maniac I am sure, and he lived in a remarkable cave close at hand; but who he is or how he came to be there in that cave I do not know.”

“Well, how you came to be up there with him running you down to stick a knife in you is what I want to know,” said Harry.

“That’s right,” Jack nodded. “Explain it, old man.”

Then Frank told them how, after the moon rose the night before, he had taken his wheel with the intention of riding around the camp, feeling he could keep watch as well that way as any. After the moon was well up, he saw there was no one anywhere about, and a desire to revisit the spot where they had seen the skeleton seized upon him. He rode to the spot, but there was no skeleton in the niche among the rocks. Leaving his bicycle, he climbed up there to examine once more, and to his astonishment, found that what seemed to be a solid, immovable stone had turned in some manner, disclosing an opening.

Then, with reckless curiosity, Frank resolved to investigate further, and he descended into the opening, found some stone steps, and was soon in a cavern. The first thing he discovered was the skeleton, still decorated as the boys had seen it in the first place, and he remained there till he found how it could be placed in view on the block of stone and then removed in a twinkling. He also found a lamp with a strong reflector, which had thrown its light on the skeleton from a hole in the rocks. There was another opening near that, where a person in the cave could look out on the desert, and Frank knew the ghostly voice they had heard must have come from that place.

Merriwell continued his investigations, having lighted the lamp, by the light of which he wandered through the cave. Suddenly he came face to face with an old man, who seemed surprised, but spoke quietly to him.

The old man declared he was “Prof. Morris Fillmore,” but did not say what he was professor of, and he volunteered to explain everything to the boy.

This he did, telling how he worked the skeleton to frighten away those who might molest him in his solitude, as he wished to be alone. There was another entrance to the cave, and, in a large, airy chamber a horse was kept. The horse was coal black, but on one side of him was drawn the outlines of the skeleton frame of a horse, and the strange old man explained that he had a suit of clothes on one side of which he had traced the skeleton of a human being. This had been done with phosphorus, and it glowed with a white light in the darkness.

The old hermit had entered the pocket and ridden near the camp of the Indians. When he turned about the skeleton tracings in phosphorus could not be seen, and so the ghostly horse and rider seemed to disappear in a most marvelous manner.

Frank questioned him concerning the treasure, and the old man seemed to grow excited and suspicious. He said something about the treasure being the property of some one who had fled from the destroying angels of the Mormons in the old days, but had perished in the desert. Frank was led to believe that the skeleton was that of the original owner of the treasure.

But when the boy would have left the cave the stranger told him he could not do so. He informed Frank that he could never go out again, and then it was that the boy became sure Fillmore was crazy.

As the man was armed, Frank decided to use strategy. First he sought to lull the man’s suspicions, and after being watched closely for hours he found a chance to slip away.

Almost immediately the man discovered what had happened and pursued. By chance Frank fled out through a passage that led upward till the top of the bluff was reached, but he fell and sprained his ankle, so he was unable to get away. The hermit followed, and the mad battle for life took place.

“Well, this is amazing!” gasped Jack. “What are you going to do with that treasure?”

“Take it to some place for safe deposit and advertise for the legal heirs of Prof. Millard Fillmore.”

“And if no heirs appear——”

“The treasure will belong to us.”

“Hurrah!”
