"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
