impelling motive was not a search for new pastures. He listened a long time until the last rumble of the hundred

thousand died away in a faint echo, and then he awakened his comrades.

"I'm thinkin'," he said, "that the presence of Urrea's band made the buffaloes move. Now I'm not a Ring Tailed Panther an' a Cheerful Talker for nothin', an' we want to hunt that band. Like as not they've been doin' some mischief, which we may be able partly to undo. I'm in favor of ridin' south, back on the herd track an' lookin' for 'em."

"So am I," said Obed White. "My watch says it's one o'clock in the morning, and my watch is always right, because I made it myself. We've had a pretty good rest, enough to go on, and what we find may be worth finding. A needle in a haystack may be well hid, but you'll find it if you look long enough."

They rode almost due south in the great path made by the buffalo herd, not stopping for a full two hours when a halt was made at a signal from the Panther. They were in a wide plain, where buffalo grass yet grew despite the winter, and the Panther said with authority that the herd had been grazing here before it was started on its night journey into the north.

"An' if we ride about this place long enough," he said, "we'll find the reason why the buffaloes left it."

He turned his horse in a circuit of the plain and Ned and Obed followed the matchless tracker, who was able, even in the moonlight, to note any disturbance of the soil. Presently he uttered a little cry and pointed ahead. Both saw the skeleton of a buffalo which evidently had been killed not long and stripped of its meat. A little further on they saw another and then two more.

"That tells it," said the Panther succinctly. "These buffaloes were killed for food an' most likely by Mexicans. It

was the shots that set the herd to runnin'. The men who killed 'em are not far away, an' I'm not a Ring Tailed Panther an' a Cheerful Talker if they don't belong to Urrea's band."

"Isn't that a light?" said Ned, pointing to the west, "or is it a firefly or something of the kind?"

A glowing spark was just visible over the plain, but as it neither moved nor went out the three concluded that it was made by a distant fire.

"I think it's in chaparral or among trees," said Obed, "or we would see it more plainly. It's a poor camp fire that hides its light under a bushel."

"I think you're right an' it must be chaparral," said the Panther. "But we'll ride toward it an' soon answer our own questions."

The light was more than a mile away and, as they advanced slowly, they saw it grow in size and intensity. It was surely a campfire, but no sound that they could yet hear came from it. They did not expect to hear any. If it was indeed Urrea and his men they would probably be sleeping soundly, not expecting any foe to be near. The Panther now dismounted, and the other two did likewise.

"No need to show too high above the plain," he said, "an' if we have to run it won't take a second to jump back on our horses."

Ned did not take the bridle of his horse as the others did. He knew that Old Jack would follow as faithful as any dog to his master, and he was right. As they advanced slowly the velvet nose more than once pressed trustfully against his elbow.

They saw now that an extensive growth of chaparral rose before them, from the center of which the light seemed to be shining. The Panther lay down on the

prairie, put his ear to the ground, and listened a long time.

"I think I hear the feet of horses movin' now an' then," he said, "an' if so, one of us had better stay behin' with ours. A horse of theirs might neigh an' a horse of ours might answer. Yon can't tell. Obed, I guess it'll be for you to stay. You've got a most soothin' disposition with animals."

"All right," said Obed philosophically, "I'd rather go on, but, if it's better for me to stay, I'll stay. They also serve who stand and hold the reins. If you find you've got to leave in a hurry I'll be here waiting."

He gathered up the reins of the three horses and remained quietly on the plain, while Ned and the Panther went forward, making straight for the light.

When they came to the edge of the chaparral they knelt among the bushes and listened. Now both distinctly heard the occasional movement of horses, and they saw the dusky outlines of several figures before the fire, which was about three hundred yards away.

"They are bound to be Mexicans," whispered the Panther, "'cause there are no Texans in this part of the country, an' you an' me, Ned, must find out just who they are."

"You lead the way, Panther," said Ned. "I'll follow wherever you go."

"Then be mighty careful. Look out for the thorns an' don't knock your rifle against any bush."

The Panther lay almost flat. His huge figure seemed to blend with the earth, and he crept forward among the thorny bushes with amazing skill. He was like some large animal, trained for countless generations to slip through thickets. Ned, just behind him, could hear only the faintest noise, and the bushes moved so little that

one, not knowing, might have credited it to the wind.

The boy had the advantage of following in the path made by the man's larger figure, and he, too, was successful in making no sound. But he could hear the stamp of horses' feet clearly now, and both to left and right he caught glimpses of them tethered in the thickets. His comrade stopped at last. They were not more than a hundred yards from the fire now, and the space in front of them was mostly open. The Panther, crouching among the bushes, raised his finger slowly and pointed toward the fire.

Ned, who had moved to one side, followed the pointing finger and saw Urrea. He was the dominant figure in a group of six or seven gathered about the flames. He was no longer in any disguise, but wore an officer's gorgeous uniform of white and silver. A splendid cocked hat was on his head, and a small gold hilted rapier swung by his side.

It may have been partly the effect of the night and the red flame, but the face of Urrea had upon Ned an effect much like that of Santa Anna. It was dark and handsome, but full of evil. And evil Ned knew Urrea to be. No man with righteous blood in his veins would play the spy and traitor as he had done.

"I could shoot him from here," whispered the Panther, who evidently was influenced in a similar way, "then reach our horses an' get away. It might be a good deed, an' it might save our lives, Ned, but I'm not able to force myself to do it."

"Nor I," said Ned. "I can't shoot an enemy from ambush."

Urrea and the other men at the fire, all of whom were in the dress of officers, were in a deep talk. Ned inferred that the subject must be of much importance, since

they sat awake, discussing it between midnight and morning.

"Look beyond the fire at the figures leanin' against the trees," whispered the Panther.

Ned looked and hot anger rose in his veins.

CHAPTER II

THE CAPTIVES

Ned had not noticed at first, but, since his eyes were growing used to the dim light, and since the Panther had pointed the way, he saw a dozen men, arms bound tightly behind them, leaning against the trees. They were prisoners and he knew instinctively that they were Texans. His blood, hot at first, now chilled in his veins. They had been captured by Urrea in a raid, and as Santa Anna had decreed that all Texans were rebels who should be executed when taken, they would surely die, unless rescue came.

"What shall we do?" he whispered.

"Nothing now," replied the Panther, in the same soft tone, "but if you an' Obed are with me we'll follow this crowd, an' maybe we can get the Texans away from 'em. It's likely that Urrea will cross
