"And so they are back on this side of the Rio Grande," said Obed White thoughtfully. "I'm not surprised. Our Texans have rejoiced too early. The full storm has not burst yet."
The Panther began to bristle. A giant in size, he seemed to grow larger, and his gorgeous hunting suit strained at the seams.
"Let 'em come on," he said menacingly. "Let Santa Anna himself lead 'em. We Texans can take care of 'em all."
But Obed White shook his head sadly.
"We could if we were united," he said, "but our leaders have taken to squabbling. You're a Cheerful Talker, Panther, and you deserve both your names, but to tell you the honest truth I'm afraid of the Mexican advance."
"I think the Mexicans probably belonged to Urrea's band," said Ned.
"Very likely," said Obed. "He's about the most energetic of their partisan leaders, and it may be that we'll run against him pretty soon."
They had heard in their scouting along the Rio Grande that young Francisco Urrea, after the discovery that he was a spy and his withdrawal from San Antonio with the captured army of Cos, had organized a strong force of horsemen and was foremost among those who were urging a new Mexican advance into Texas.
"It's pretty far west for the Mexicans," said the Panther. "We're on the edge of the Indian country here."
But Obed considered it all the more likely that Urrea, if he meditated a raid, would come from the west, since his approach at that point would be suspected the least. The three held a brief discussion and soon came to an agreement. They would continue their own ride west and look for Urrea. Having decided so, they went into the task heart and soul, despite its dangers.
The three rode side by side and three pairs of skilled eyes examined the plain. The snow was left only in sheltered places or among the trees. But the further they went the scarcer became the trees, and before night they disappeared entirely.
"We are comin' upon the buffalo range," said the Panther. "A hundred miles further west we'd be likely to strike big herds. When we're through fightin' the Mexicans I'm goin' out there again. It's the life fur me."
The night came, dark and cold, but fortunately without wind. They camped in a dip and did not light any fire, lying as Ned had done the night before on their horse blankets and wrapping themselves in their own. The three horses seemed to be contented with one another and made no noise.
They deemed it wise now to keep a watch, as they might be near Urrea's band or Lipans might pass, and the Panther, who said he was not sleepy at all, became sentinel. Ned, although he had not risen until noon, was sleepy again from the long ride, and his eyes closed soon. The last object that he saw was the Panther standing on the crest of the swell just beyond them, rifle on shoulder, watching the moonlit plains. Obed White was asleep already.
The Panther walked back and forth a few times and then looked down at his comrades in the dip. His trained eyes saw their chests rising and falling, and he knew that they were far away in the land of Nowhere. Then he extended his walk back and forth a little further, scanning carefully the dusky plain.
A light wind sprang up after a while, and it brought a low but heavy and measured tread to his ears. The Panther's first impulse was to awaken his friends, because this might be the band of Urrea, but he hesitated a moment, and then lay down with his ear to the earth. When he rose his uneasiness had departed and he resumed his walk back and forth. He had heard that tread before many times and, now that it was coming nearer, he could not mistake it, but, as the measured beat indicated that it would pass to one side, it bore no threat for his comrades or himself.
The Panther did not stop his walk as from a distance of a few hundred yards he watched the great buffalo herd go by. The sound was so steady and regular that Ned and Obed were not awakened nor were the horses disturbed. The buffaloes showed a great black mass across the plain, extending for fully a mile, and they were moving north at an even gait. The Panther watched until the last had passed, and he judged that there were fully a hundred thousand animals in the herd. He saw also the big timber wolves hanging on the rear and flanks, ready to cut out stray calves or those weak from old age. So busy were the wolves seeking a chance that they did not notice the gigantic figure of the man, rifle on shoulder, who stood on the crest of the swell looking at them as they passed.
The Panther's eyes followed the black line of the herd until it disappeared under the northern rim of darkness. He was wondering why the buffaloes were traveling so steadily after daylight and he came to the conclusion that the 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
