At the first streak of dawn he was up, and within a short half-mile, thanks to the snowy mare, he found the band. At his approach, the shrill neigh of the Pacer bugled his troop into a flying squad. But on the first mesa they stopped, and faced about to see what this persistent follower was, and what he wanted. For a moment or so they stood against the sky to gaze, and then deciding that he knew him as well as he wished to, that black meteor flung his mane on the wind, and led off at his tireless, even swing, while the mares came streaming after.
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. And 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 Charley 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 tiring 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.
