Shoving rapidly into the mountains, Sliver ascended with the trail in a couple of hours through upland growth of piñon and juniper to the height of land, a pass riven by earthquake or subsidence between twin jagged peaks, from where he overlooked the valley pasture.

Like a great jade bowl, bisected by the silver line of a stream, its wide green circle, miles in diameter, lay within a broad ring of purple chaparral. Over its surface black dots were scurrying toward the corrals at the northern end, and under Sliver’s glass these resolved into horses that were being rounded up by four Mexicans; for he could see their peaked sombreros, tight charro suits, even at that distance. Turning the glass on the jacal, a rude hut of poles and grass thatch near the corrals, he looked for Pedro, the anciano.

“Poor old chap! they’ve sure got his goat.” While clucking his commiseration, however, he shifted the glass to a patch of white on a near-by tree, and it immediately resolved into the old fellow’s blouse and calzones. “No, they’ve just tied him up. Then these ain’t no Colorados. It’s Felicia’s gang, all right, all right.” He added, chuckling, “Four nice little raiders in a pretty trap, along comes Jake and Bull, then there was none.”

And trapped they were. Except where the stream slipped out over a precipice between two narrow walls, the mountains rose sheer around the Bowl, unscalable save where the trail rose by precarious zigzags to where Sliver held the pass a thousand feet above. At few places was it possible for two horsemen to ride abreast. At that point there was barely room for one; if necessary, he could have held it, alone, against a score. But it was not. Watching closely, he saw the raiders first drive the horses into the corrals, then settle down for a siesta in the shade of the jacal.

“Going to bring ’em up at sundown,” he muttered, “in time to make the first run by night.”

So certain he was of it that he did not scruple to take a sleep himself; cat-napped, with occasional squints down into the valley up to the moment that he was awakened by the hoof-beats of Jake and Bull’s beasts. The glass then showed the raiders working the horses out of the corrals. As the herd thinned out to single file at the trail, one man took the lead; a second and third fell in at even distances; the last brought up the rear.

“They know their business,” Bull commented on the manœuver. “It’s easier to keep ’em moving.” He grimly added: “And easier for us. The line will string out for a quarter-mile, so I’ll go down that distance an’ hide in the chaparral. Let the last man pass me before you hold up the first. Then, while one of you keeps him covered, t’other can take away his tools. I’ll keep ’em moving on up till you’ve got the other three.”

While Jake took away and tied their horses, Bull gained his position. By that time the leading raider had gained a like distance uphill and, peeping, Bull watched the thin file of animals wriggling like a slow black snake up the yellow trail. So clear was the air he could hear, above the thud and scrape of hoofs, the raiders calling to one another. Now they were directly beneath him; so close that he could plainly see the leader’s face, ugly, pock-marked. As he withdrew into the chaparral Bull carried with him an irritatingly haunting remembrance. Somewhere, though he could not place it, he had seen the man before! He was still puzzling over it when Jake’s command rang out in Spanish:

“Hands up!”

The leader looked and complied, persuaded by the black muzzles, wicked eyes, that looked down from the rock above. The second and third men did try to turn, but were blocked by the file of animals. An attempt to pass would have sent them down, bounding from level to level to the floor of the valley below. The fourth man swung his beast around only to find himself looking into Bull’s rifle. So while Jake covered the operation from above and Bull from below, Sliver disarmed and bound the raiders.
