Away they went, circling now to the west, and after several repetitions of this same play, flying, following, and overtaking, and flying again, they passed, near noon, the old Apache look-out, Buffalo Bluff. Anti here, on watch, was Jo. A long thin column of smoke told Charley to come to camp, and with a flashing pocket-mirror he made response. Jo, freshly mounted, rode across, and again took up the chase, and back came Chancy to camp to eat and rest, and then move on up stream.
All that day Jo followed, and managed, when it was needed, that the herd should keep the great circle, of which the wagon cut a small chord. At sundown he came to Verde Crossing, and there was Charley with a fresh horse and food, and Jo went on in the same calm, dogged way. All the evening he followed, and far into the night, for the wild herd was now getting somewhat used to the presence of the harmless strangers, and were more easily followed; moreover, they were thing out with perpetual traveling. They were no longer in the good grass country, they were not grain-fed like the horses on their track, and above all, the slight but continuous nervous tension was surely telling. It spoiled their appetites, but made them very thirsty. They were allowed, and as far as possible encouraged, to drink deeply at every chance. The effect of large quantities of water on a running animal is well known; it tends to stiffen the limbs and spoil the wind. Jo carefully guarded his own horse against such excess, and both he and his horse were fresh when they camped that night on the trail of the jaded mustangs.
At dawn he found them easily close at hand, and though they ran at first they did not go far before they dropped into a walk. The battle seemed nearly won now, for the chief difficulty in the 'walk-down' is to keep track of the herd the first two or three days when they are fresh.
All that morning Jo kept in sight, generally in close sight, of the band. About ten o'clock, Charley relieved him near Jos. Peak and that day the mustangs walked only a quarter of a mile ahead with much less spirit than the day before and circled now more north again. At night Charley was supplied with a fresh horse and followed as before.
Next day the mustangs walked with heads held low, and in spite of the efforts of the Black Pacer at times they were less than a hundred yards ahead of their pursuer.
The fourth and fifth days passed the same way, and now the herd was nearly back to Antelope Springs. So far all had come out as expected. The chase had been in a great circle with the wagon following a lesser circle. The wild herd was back to its starting-point, worn out; and the hunters were back, fresh and on fresh horses. The herd was kept from drinking till late in the afternoon and then driven to the Springs to swell themselves with a perfect water gorge. Now was the chance for the skilful ropers on the grain-fed horses to close in, for the sudden heavy drink was ruination, almost paralysis, of wind and limb, and it would be easy to rope and hobble them one by one.
There was only one weak spot in the programme, the Black Stallion, the cause of the hunt, seemed made of iron, that ceaseless swinging pace seemed as swift and vigorous now as on the morning when the chase began. Up and down he went rounding up the herd and urging them on by voice and example to escape. But they were played out. The old white mare that had been such help in sighting them at night, had dropped out hours ago, dead beat. The half-bloods seemed to be losing all fear of the horsemen, the band was clearly in Jo's power. But the one who was the prize of all the hunt seemed just as far as ever out of reach.
Here was a puzzle. Jo's comrades knew him well and would not have been surprised to see him in a sudden rage attempt to shoot the Stallion down. But Jo had no such mind. During that long week of following he had watched the horse all day at speed and never once had he seen him gallop.
The horseman's adoration of a noble horse had grown and grown, till now he would as soon have thought of shooting his best mount as firing on that splendid beast.
Jo even asked himself whether he would take the handsome sum that was offered for the prize. Such an animal would be a fortune in himself to sire a race of pacers for the track.
But the prize was still at large—the time had come to finish up the hunt. Jo's finest mount was caught. She was a mare of Eastern blood, but raised on the plains. She never would have come into Jo's possession but for a curious weakness. The loco is a poisonous weed that grows in these regions. Most stock will not touch it; but sometimes an animal tries it and becomes addicted to it.
It acts somewhat like morphine, but the animal, though sane for long intervals, has always a passion for the herb and finally dies mad. A beast with the craze is said to be locoed. And Jo's best mount had a wild gleam in her eye that to an expert told the tale.
But she was swift and strong and Jo chose her for the grand finish of the chase. It would have been an easy matter now to rope the mares, but was no longer necessary. They could be separated from their black leader and driven home to the corral. But that leader still had the look of untamed strength. Jo, rejoicing in a worthy foe, went bounding forth to try the odds. The lasso was flung on the ground and trailed to take out every kink, and gathered as he rode into neatest coils across his left palm. Then putting on the spur the first time in that chase he rode straight for the Stallion a quarter of a mile beyond. Away he went, and away went Jo, each at his best, while the fagged-out mares scattered right and left and let them pass. Straight across the open plain the fresh horse went at its hardest gallop, and the Stallion, leading off, still kept his start and kept his famous swing.
It was incredible, and Jo put on more spur and shouted to his horse, which fairly flew, but shortened up the space between by not a single inch. For the Black One whirled across the flat and up and passed a soap-weed mesa and down across a sandy treacherous plain, then over a grassy stretch where prairie dogs barked, then hid below, and on came Jo, but there to see, could he believe his eyes, the Stallion's start grown longer still, and Jo began to curse his luck, and urge and spur his horse until the poor uncertain brute got into such a state of nervous fright, her eyes began to roll, she wildly shook her head from side to side, no longer picked her ground—a badger-hole received her foot and down she went, and Jo went flying to the earth. Though badly bruised, he gained his feet and tried to mount his crazy beast. But she, poor brute, was done for—her off fore-leg hung loose.
There was but one thing to do. Jo loosed the cinch, put Lightfoot out of pain, and carried back the saddle to the camp. While the Pacer steamed away till lost to view.
This was not quite defeat, for all the mares were manageable now, and Jo and Charley drove them carefully to the 'L cross F' corral and claimed a good reward. But Jo was more than ever bound to own the Stallion. He had seen what stuff he was made of, he prized him more and more, and only sought to strike some better plan to catch him.

The cook on that trip was Bates—Mr. Thomas Bates, he called himself at the post-office where he regularly went for the letters and remittance which never came. Old Tom Turkeytrack, the boys called him, from his cattle-brand, which he said was on record at Denver, and which, according to his story, was also borne by countless beef and saddle stock on the plains of the unknown North.
When asked to join the trip as a partner, Bates made some sarcastic remarks about horses not fetching $12 a dozen, which had been literally true within the year, and he preferred to go on a very meagre salary. But no one who once saw the Pacer going had failed to catch the craze. Turkeytrack experienced the usual change of heart. He now wanted to own that mustang. How this was to be brought about he did not clearly see till one day there called at the ranch that had 'secured his services,' as he put it, one, Bill Smith, more usually known as Horseshoe Billy, from his cattle-brand. While the excellent fresh beef and bread and the vile coffee, dried peaches and molasses were being consumed, he of the horseshoe remarked, in tones which percolated through a huge stop-gap of bread:
