"I'm reckonin' there's a mind behind them Greasers," replied Jim. "Or mebbe we ain't done Rojas credit...If somethin' would only come off!"

That Lash, the coolest, most provokingly nonchalant of men in times of peril, should begin to show a nervous strain was all the more indicative of a suble pervading unreality.

"Boys, look sharp!" suddenly called Lash. "Low down to the left --mebbe three hundred yards. See, along by them seams of lava --behind the choyas. First off I thought it was a sheep. But it's the Yaqui!...Crawlin' swift as a lizard! Can't you see him?"

It was a full moment before Jim's companions could locate the Indian. Flat as a snake Yaqui wound himself along with incredible rapidity. His advance was all the more remarkable for the fact that he appeared to pass directly under the dreaded choyas. Sometimes he paused to lift his head and look. He was directly in line with a huge whorl of lava that rose higher than any point on the slope. This spur was a quarter of a mile from the position of the rangers.

"Shore he's headin' for that high place," said Ladd. "He's goin' slow now. There, he's stopped behind some choyas. He's gettin' up--no, he's kneelin'....Now what the hell!"

"Laddy, take a peek at the side of that lava ridge," sharply called Jim. "I guess mebbe somethin' ain't comin' off. See! There's Rojas an' his outfit climbin'. Don't make out no hosses....Dick, use your glass an' tell us what's doin'. I'll watch Yaqui an' tell you what his move means."

Clearly and distinctly, almost as if he could have touched them, Gale had Rojas and his followers in sight. They were toiling up the rough lava on foot. They were heavily armed. Spurs, chaps, jackets, scarfs were not in evidence. Gale saw the lean, swarthy faces, the black, straggly hair, the ragged, soiled garments which had once been white.

"They're almost up now," Gale was saying. "There! They halt on top. I see Rojas. He looks wild. By----! fellows, an Indian! ...It's a Papago. Belding's old herder!...The Indian points-- this way--then down. He's showing Rojas the lay of the trail."
