At five in the afternoon they forded the Black River at a point where it crossed the state line from New Mexico, and at dusk camped at the base of the Guadalupe Mountains. At daybreak they took up the chase, grim and merciless, and shortly afterward they passed the smoldering remains of a camp fire, showing that the pursued had been in a great hurry, for it should have been put out and masked. At noon they left the mountains to the rear and sighted the Barred Horeshoe, which they approached. The owner of the ranch saw them coming, and from their appearance surmised that something was wrong. “What is it?” He shouted. “Rustlers?” “Nope. Murderers. I wants to swap cayuses quick,” answered Buck. “There they are. Th' boys just brought 'em in. Anything else I can let yu have?” “Nope,” shouted Buck as they galloped off. “Somebody's goin' to get plugged full of holes,” murmured the ranch owner as he watched them kicking up the dust in huge clouds. After they had forded a tributary of the Rio Penasco near the Sacramento Mountains and had surmounted the opposite bank, Hopalong spurred his horse to the top of a hummock and swept the plain with Pete's field glasses, which he had borrowed for the occasion, and returned to the rest, who had kept on without slacking the pace. As he took up his former position he grunted, “War-whoops,” and unslung his rifle, an example followed by the others. The ponies were now running at top speed, and as they shot over a rise their riders saw their quarry a mile and a half in advance. One of the Indians looked back and discharged his rifle in defiance, and it now became a race worthy of the name--Death fled from Death. The fresher mounts of the cowboys steadily cut down the distance and, as the rifles of the pursuers began to speak, the hard-pressed Indians made for the smaller of two knolls, the plain leading to the larger one being too heavily strewn with bowlders to permit speed. As the fugitives settled down behind the rocks which fringed the edge of their elevation a shot from one of them disabled Billy's arm, but had no other effect than to increase the score to be settled. The pursuers rode behind a rise and dismounted, from where, leaving their mounts protected, they scattered out to surround the knoll.
