The cibolero had but little fear of meeting one or two of them. He rode a horse in which he had full confidence; and he knew that no Pane could overtake him; but he might be surrounded by numbers, and intercepted before he could reach the Waco lodges. That was the reason why he advanced with so much caution.

His ears were set to listen attentively. Every sound was noted and weighed--the "gobble" of the wild turkey from the branches of the oak; the drumming of the ruffed grouse on some dry knoll; the whistling of the fallow-deer; or the tiny bark of the prairie marmot. All these were well-known sounds; and as each was uttered, the cibolero stopped and listened attentively. Under other circumstances he would not have heeded them, but he knew that these sounds could be imitated, and his ear was bent to detect any counterfeit. He could distinguish the Pane trail of the previous night. A strong band there must have been, by the numerous tracks on the grass. At the crossing of a stream Carlos could detect the prints of moccasins in the sand. There were still some of the party afoot then, though, no doubt, the stolen _mulada_ had mounted a good many.

Carlos rode on with more caution than ever. He was half-way to the Waco village, and still the Pane trail led in that direction. Surely these could not have passed without finding it? Such skilled warriors as the Panes would not. They would see the trail of the Wacoes leading to the cibolero's own camp--they would soon discover the lodges--perhaps they had already made their attack--perhaps--

The reflections of the cibolero were suddenly interrupted; distant sounds fell upon his ear--shouts and cries of fearful import--with that continued murmur that results from the mingling of many voices in loud and confused clamour. Now and then was heard a whoop, or a cheer, or a shrill whistle, rising above the ordinary noises, and carrying far over the plain its tones of triumph or revenge.

Carlos knew the import of those shouts and cries--they were the sounds of battle!--of terrible and deadly strife!

They came from behind the hill--the cibolero was just climbing it.

He spurred his horse, and, galloping forward to its crest, looked down into the valley. The conflict was raging before him!

He had a full view of the dreadful scene. Six hundred dusky horsemen were riding about on the plain; some dashing at each other with couched lances--some twanging their bows from a distance; and others close together in the hand-to-hand combat of the deadly tomahawk! Some were charging in groups with their long spears--some wheeling into flight, and others, dismounted, were battling on foot! Some took shelter among the timber islands, and sprang out again as they saw an opportunity of sending an arrow, or lancing a foeman in the back; and so the red contest continued.

Not a shot was heard--neither bugle nor drum sent forth their inspiring notes--no cannon rolled its thunder--no rocket blazed--no smoke spread its sulphury cloud upon the air; but without these sights and sounds there was no fear of mistaking that contest for a mimic game--a tournament of the prairies. The wild war-whoop, and the wilder whistle--the earnest onslaught--the fierce charging cheer--the cries of triumph and vengeance--the neighing steeds without riders--here and there the prostrate savage, with skinless scalp, glaring red in the sun--the spears and hatchets crimsoned with blood,--all were evidence of real and deadly strife, and Carlos did not doubt for a moment the character of the scene. Before him was an Indian fight--Waco and Pane engaged in the earnest struggle of life and death!

All this he comprehended at a glance, and, after regarding the fight for a moment, he could distinguish the warriors of both tribes from one another. The Panes, in full war-costume, were easily recognised by their tufted scalp-locks; while the Wacoes, who had, no doubt, been taken by surprise, were many of them in hunting-shirts and leggings.

Some, however, were nearly as naked as their adversaries; but easily distinguished from them by their full flowing hair.

The first impulse of the cibolero was to gallop forward and mingle in the fight,--of course, taking side with the Wacoes. The sound of the conflict roused his blood, and the sight of the robbers who had so lately ruined him rendered him eager for revenge. Many of them were mounted upon the very mules they had taken from him, and Carlos was determined to have some of them back again.

He was about to put spurs to his horse, and dash forward, when a sudden change seemed to occur in the conflict that decided him to remain where he was. The Panes were giving way!

Many of them were seen wheeling out of the plain, and taking to flight.

As Carlos looked down the hill, he saw three of the Pane warriors in full run, making up to the spot where he stood. Most of the band were still fighting, or had fled in a different direction; but these, cut off from the rest, came directly up the hill at a gallop.

The cibolero had drawn his horse under the cover of some trees, and was not perceived by them until they were close to the spot.

At this moment the war-cry of the Wacoes was heard directly in their rear, and Carlos saw that two mounted warriors of that tribe were in pursuit. The fugitives looked back, and, seeing only two adversarios after them, once more wheeled round and gave fight.

At their first charge one of the pursuers was killed, and the other-- whom Carlos now recognised as the Waco chief--was left alone against three assailants.

The whip-like crack of the cibolero's rifle sounded on the air, and one of the Panes dropped out of his saddle. The other two, ignorant of whence the shot had come, continued their onset on the Waco chief, who, dashing close up, split the skull of one of there with his tomahawk.

His horse, however, bore him rapidly past, and before he could wheel round, the remaining Pane--an active warrior--rushed after and thrust his long spear into the back of the chief. Its head passed clear through his body, completely impaling him; and with a death-whoop, the noble Indian fell from his horse to the ground.

But his enemy fell at the same time. The arrow of the cibolero was too late to save, though not to avenge, the Waco's fall. It pierced the Pane just at the moment the latter had made his thrust, and he fell to the ground simultaneously with his victim, still clutching the handle of the spear!

A fearful group lay dead upon the sward; but Carlos did not stay to contemplate it. The fight still raged in another part of the field, and, putting spurs to his horse he galloped off to take part in it.

But the Panes had now lost many of their best warriors, and a general panic had seized upon them, ending in their full flight. Carlos followed along with the victorious pursuers, now and then using his rifle upon the fleeing robbers. But fearing that a stray party of them might attack his own little camp he turned from the line of pursuit, and galloped in that direction. On arriving, he found Antonio and the peons fortified within their corral, and all safe. Stray Indians had passed them, but all apparently too much frightened to have any desire for an attack upon the little party.

As soon as the cibolero had ascertained these facts, he turned his horse and rode back toward the scene of the late conflict.

CHAPTER SIXTEEN.

As Carlos approached the spot where the chief had been slain he heard the death-wail chanted by a chorus of voices.

On getting still nearer, he perceived a ring of warriors dismounted and standing around a corpse. It was that of the fallen chief. Others, fresh from the pursuit, were gathering to the place; each taking up the melancholy dirge as he drew nigh.

The cibolero alighted, and walked forward to the ring. Some regarded him with looks of surprise, while others, who knew he had aided them in the fight, stepped up and grasped him by the hand. One old warrior taking Carlos' arm in his, led him forward to the ring, and silently pointed to the now ghastly features, as though he was imparting to the cibolero the news that their chief was dead!

Neither he nor any of the warriors knew what part Carlos had borne in the affair. No one, now alive, had been witness to the conflict in which the chief had fallen. Around the spot were high copses that hid it from the rest of the field, and, at the time this conflict occurred, the fight was raging in a different direction. The warrior, therefore, thought he was imparting to Carlos a piece of news, and the latter remained silent.

But there was a _mystery_ among the braves, and Carlos saw this by their manner. Five Indians lay dead upon the ground _unscalped_! That was the mystery. They were the three Panes, and the chief with the other Waco. They could not have slain each other, and all have fallen on the spot. That was not probable. The Waco and one of the Panes lay apart.

The other three were close together, just as they had fallen, the chief impaled by the Pane spear, while his slayer lay behind him still grasping the weapon! The red tomahawk was clutched firmly in the hands of the chief, and the cleft skull of the second Pane showed where it had last fallen.

So far the Indians translated the tableau, but the mystery lay not there. Who had slain the slayer of their chief? That was the puzzle.

Some one must have survived this deadly strife, where five warriors had died together!

If a Pane, surely he would not have gone off without that great trophy which would have rendered him famous for life,--the scalp of the Waco chief? If a Waco, where and who was he?

These questions passed from lip to lip. No one was found to answer them, but there were yet some warriors to return from the pursuit, and the inquiry was suspended, while the death-song was again chanted over the fallen chief.

At length all the braves had arrived on the spot, and stood in a circle around the body. One of the warriors stepped forward to the midst, and by a signal intimated that he wished to be heard. A breathless silence followed, and the warrior began:--

"Wacoes! our hearts are sad when they should otherwise rejoice. In the midst of victory a great calamity has fallen upon us. We have lost our father,--our brother! Our great chief--he whom we all loved--has fallen. Alas! In the very hour of triumph, when his strong right hand had hewn down his enemy on the field--in that moment has he fallen!

"The hearts of his warriors are sad, the hearts of his people will long be sad!

"Wacoes! our chief has not fallen unrevenged. His slayer lies at his feet pierced with the deadly dart, and weltering in his blood. Who of you hath done this?"

Here the speaker paused for a moment as if waiting for a reply. None was given.

"Wacoes!" he continued, "our beloved chief has fallen, and our hearts are sad. But it glads them to know that his death has been avenged.

There lies his slayer, still wearing his hated scalp. What brave warrior claims the trophy? Let him stop forth and take it!"

Here there was another pause, but neither voice nor movement answered the challenge.

The cibolero was silent with the rest. He did not comprehend what was said, as the speech was in the Waco tongue, and he understood it not.

He guessed that it related to the fallen chief and his enemies, but its exact purport was unknown to him.

"Brothers!" again resumed the orator, "brave men are modest and silent about their deeds. None but a brave warrior could have done this. We know that a brave warrior will avow it. Let him fear not to speak. The Wacoes will be grateful to the warrior who has avenged the death of their beloved chief."

Still the silence was unbroken, except by the voice of the orator.

"Brother warriors!" he continued, raising his voice and speaking in an earnest tone, "I have said that the Wacoes will be grateful for this deed. I have a proposal to make. Hear me!"

All signified assent by gestures.

"It is our custom," continued the speaker, "to elect our chief from the braves of our tribe. I propose that we elect him _now_ and _here_-- here! on the red field where his predecessor has fallen. _I propose for our chief the warrior who has done this deed_!" And the orator pointed to the fallen Pane.

"_My_ voice for the brave who has avenged our chief!" cried one.

"And mine!" shouted another.
