Ordinarily they would have lingered to accept the strained hospitality of the settlement. But this was duty, duty large and grave, and, conscious of it all, they pressed forward in silence. The renegades'

tracks stood out clearly, and the rangers noted that some of the horses were shod, others only half shod, while the greater number were without shoes at all. This told of the marauders' nondescript collection of mounts, and also acquainted them with the fact that many of the animals had been stolen. On through the afternoon they rode, making but little gain, since the tracks became no fresher. When darkness fell, though still in the open without protection of any kind save that offered by a slight rise of ground, they dismounted and prepared to make camp.

Throughout the afternoon Pat had felt something of the grim nature of this business. This not only because of the severe crowding which he had endured--though that had told him much--but because of the unwonted silence upon the men. So he had held himself keenly to the stride, rather liking its vigor after long days of walking, finding himself especially fit to meet it after his recent change of food. And although the sun had been swelteringly hot, yet the desert had been swept with counteracting breezes, and, with night finally descending, he had felt more than ever his fine mettle, and now, even though his master was painfully dismounting, he felt fit to run his legs off at the least suggestion.

This fitness remained with him. When his young master turned him loose at the end of a generous tether, he stepped eagerly away from the firelight and out into the light of a rising moon, not to graze, for he felt no desire to graze, having eaten his fill and more at noon, but to give vent to his high spirits in unusual rolling in the sands. This he quickly proceeded to do, kicking and thrashing about, and holding to it long after the men about the fire had ceased to come and go in preparing their meal, long after they had seated themselves in the cheerful glow, smoking and talking as was their habit.

The Professor noticed it. He looked at the man with the beard pointedly.

"That Pat hoss he's workin' up another job o' cleanin' for you," he observed. "Seemed in an awful hurry, too," he added, then dropped his eyes innocently.

The other was punching new holes in his belt with an unwieldy jack-knife. He suddenly gave off twisting the point of the knife against the leather and lifted it menacingly in the direction of his tormentor.

"Look-a-here, Professor," he retorted, "I ain't feelin' any too pert right now, and I'll take a hop out o' you if you don't shet up!"

The Professor looked grieved. "What's the matter of you?" he inquired.

"Never you mind!" The knife went back to the leather again. "Let that horse roll if he wants to! It ain't any skin off your hands!"

Which was the key-note of all a.s.sembled save the Professor. All except him appeared tense and nervous and in no way inclined to joke. For a time after the lean man's rebuke they engaged in casual talk, then one after another they drew off their boots and rolled up in their blankets.

All but Stephen. His arm was throbbing with unusual pain. It was still in splints, and still bandaged in a sling around his neck, and since it always hurt him to change positions, he remained seated beside the fire, wrapped in sober thought. Outside, in the green-white light of the moon, he heard the horses one by one sink to rest. Around him the desert, gripped in death-stillness, pressed close, while overhead the star-sprinkled dome of heaven, unclouded, arched in all its wonted glittering majesty. A long time he sat there, keenly alive to these things, yet thinking strange thoughts, thoughts of his loneliness, and what might have been, and where he might have been, had he never met the girl. These were new thoughts, and he presently arose to rid himself of them and turned in, and soon was in a doze.

Some time later, he did not know how much later, he was aroused by a sound as of distant thunder. But as he lifted his head the sound disappeared. Yet when he dropped his head back again he heard it. He pressed his left ear close to earth. The sound grew louder and seemed to come nearer. Again he lifted his head. As before, he could hear nothing save the snoring of the large man and the dream-twitching of the Professor. He gazed about him. The camp was still. He peered outside in the moonlight. The horses were all down--at rest. At length he dropped back once more, closed his eyes sleepily, and soon dozed a second time.

But again he was aroused. He whipped up his head. The sound was thundering in his ears. He heard trampling hoofs--many hoofs--immediately outside. He leaped to his feet. He saw hors.e.m.e.n--Indians--the renegades--crowding past, riding frantically to the north. He called sharply to the others, who were already waking and leaping to their feet. He turned to the horses. They were all there, standing now, alert and tense. Wheeling, he stared after the Indians.

They were speeding away like the wind, close huddled, fleeing in a panic. He watched them, dazed, saw them ascend a rise, become a vacillating speck in the moonlight, and drop from view in a hollow beyond the rise. He turned to the men. All stood in mute helplessness, only half comprehending. He opened his mouth to speak, but as he did so there came a sudden interruption.

It was a bugle-call, rollicking across the desert, crashing into the death-like hush which had settled upon the camp. He turned his eyes toward the sound--to the south. Over a giant sand-dune, riding grouped, with one or two in the lead, swept a company of cavalrymen. Down the slope they galloped, moonlight playing freely upon them, bringing out every detail--the glint of arms, the movement of hat-brims, the lift and fall of elbows--pounding straight for the camp. Another blast of the bugle, crisp and metallic, and they swerved; they drew near, nearer still, came close on the right, and swept past in a whirlwind of sounds, thundering hoofs, cursing men, slamming carbines, creaking saddles, snorting horses. So they swept on into the north, pushing, crowding, jostling, throwing back flying gravel, odors of sweat, swirling dust-clouds. They mounted rapidly over the rise, and became, as the pursued, vacillating specks, and then disappeared in the hollow beyond.

Stephen recovered himself. He swept his eyes again over the horses. He saw a change among them. Three were calm, but not the other two. Both of them were weaving faintly, and, even as he sprang to them, one sank slowly to the ground. Wondering, dazed, gripped in apprehension, he bent over it. The horse was a stranger, and it was gasping its last breath.

Dismayed, he turned to the other. This horse also was a strange horse, and it was white with foam and panting, also run to death. Astonished, cold with apprehension, he looked for Pat. But neither Pat nor the sorrel was to be seen. Then the truth overwhelmed him. The renegades, seeing fresh horses here, had made a swift change. Pat was gone!

For one tense moment he stood spellbound. Then he sprang into action. He dressed as best he could, called to the others to bridle and saddle a horse, and leaped into the saddle. His whole body rebelled at the movement. But he set his jaw grimly, and, clutching at his bandaged arm, yet keeping his grip on the reins, he spurred frantically after the cavalry. As he dashed away he shouted back his purpose.

But the men, standing with wide eyes turned after him, heard only the end:

"I'll get him in spite of h.e.l.l!"

CHAPTER XX

FIDELITY

Meantime Pat was running at top speed across the desert. Yet he was trying to understand this strange call to duty. Roused from fitful slumber by trampling hoofs, he had felt an excited hand jerking him to his feet, and after that a slender rope looped round his lower jaw. Then he had been urged, with a wriggling form on his bare back, frantic heels drumming his sides, and a strange voice impelling him onward past a surging crowd of hors.e.m.e.n, still only half awake, out into the open.

When he was well in the fore, he had found himself crowded to his utmost--over sand-dune, into arroyo, across the level--around him thundering hoofs, panting horses, silent men, all speeding forward in the glorious moonlight. It was a strange awakening, yet he had not entertained thoughts of rebellion, despite the fact that he had not liked the flaying rope, the soft digging heels, the absence of bridle and saddle. It was strange; it was not right. None of it had checked up with any item of his experience. Yet, oddly enough, he had not rebelled.

Nor was he harboring thoughts of rebellion now. Racing onward, smarting with each swing of the lash, he found himself somehow interested solely in holding his own with the other horses. Suddenly, alert to their movements, he saw a cleft open in their surging ranks, made by the fall of an exhausted horse. Yet the others did not stop. They galloped on, unheeding, though he himself was jerked up. Then followed a swift exchange of words, and then the unhorsed man mounted behind Pat's new master. Carrying a double load now, Pat nevertheless dashed ahead at his former speed, stumbling with his first steps, but soon regaining his stride and overtaking the others. And though it cost him straining effort, he felt rewarded for his pains when one of the men uttered a grunt which he interpreted as approval. But it was all very strange.

A canyon loomed up on his left. He had hardly seen the black opening when he was swung toward it. He plunged forward with the other horses, and was the first to enter the canyon's yawning mouth. Between its high walls, however, he found himself troubled by black shadows. Many of them reached across his path like projections of rock, and more than once he faltered in his stride. But after pa.s.sing through two or three in safety he came at length to understand them and so returned to his wonted self-possession.

But he was laboring heavily now. His heart was jumping and pounding, his breath coming in gasps, but he held to the trail, moving ever deeper into the hills, until he burst into a basin out of which to the right led a narrow canyon. Then he slowed down and, turning into the canyon, which wound and twisted due north and south in the bright moonlight, he continued at a slower pace. But his heart no longer was in the task. The weight on his back seemed heavier; there was a painful swelling of his ankles. He knew the reason for this pain. It had come from unwonted contact with hard surfaces and frequent stepping on loose stones in this strange haste with a strange people in the hills. Yet he kept on, growing steadily more weary, yet with pride ever to the fore, until a faint light began to streak the overhead sky, stealing cautiously down the ragged walls of the canyon. Then he found himself pulled into a walk.

He was facing a narrow defile that wound up among the overhanging crags.

Glad of the privilege of resting, for a walk was a rest with him now, he set forward into the uninviting pa.s.s. Up and up he clambered, crowding narrowly past boulders, rounding on slender ledges, up and ever up. As he ascended he saw gray-white vales below, felt the stimulus of a rarer air, and at last found his heart fluttering unpleasantly in the higher alt.i.tude. Yet he held grimly to his task, and, when broad daylight was streaming full upon him, he found himself on a wide shelf of rock, a ledge falling sheer on one side to unseen depths, towering on the other to awe-inspiring heights. Here he came to a halt. And then, so tired was he, so faint with exhaustion, so racked of body and spirit, that he sank upon the cool rock even before the men could clear themselves from him, and lay there on his side, his eyes closed, his lungs greedily sucking air.

The glare of full daylight aroused him. Regaining his feet, he stared about him. He saw many strange-looking men, and near them many dirty and bedraggled horses. He turned his eyes outward from the ledge. He saw around him bristling peaks, and below them, far below, a trailing canyon, winding in and out among hills toward the rising sun, and terminating in a giant V, beyond which, a connecting thread between its sloping sides, lay an expanse of rolling mesa. It was far from him, however--very, very far--and he grew dizzy at the view, finding himself more and more unnerved by the height. At length he turned away and swept his eyes again over the horses, where he was glad to find the rangy sorrel. Then he turned back to the men, some of whom were standing, others squatting, but all in moody silence.

As he looked he grew aware that a pair of dark eyes were fixed upon him.

He stared back, noting the man's long hair and painted features and the familiar glow of admiration in his eyes. Believing him to be his new master, he continued to regard him soberly until the man, with a grunt and a grimace, rose and approached him. Pat stood very still under a rigid examination. The man rubbed his ankles, turned up his hoofs, looked at his teeth; and at the conclusion of all this Pat felt that he had met with approval. Also, he realized that he rather approved of the man. Then came a volley of sounds he did not understand, and he found himself touched with grave apprehension. But not for long. The man led him across the ledge to a tiny stream trickling down the rocks, walking with a quiet dignity he long since had learned to connect with kindliness. This and the fact that he led him to water determined his att.i.tude.

Toward noon, as he was brooding over hunger pangs, he was startled by excited gutturals among the men. Gazing, he saw one of the men standing on the edge of the shelf, pointing out through the long canyon. With the others, Pat turned his eyes that way. Between the distant V dotting the mesa beyond rode a body of hors.e.m.e.n. They were not more than specks to his eyes, proceeding slowly, so slowly, in fact, that while he could see they were moving he yet could not see them move as they crawled across the span between the canyon's mouth. Interested, gripped in the contagion of the excitement round him, he kept his eyes upon the distant specks until the sun had changed to another angle. But even after this lapse of time, so distant were the hors.e.m.e.n, so wide the canyon's mouth, they had traveled only half-way across the span. Yet he continued to watch, wondering at the nervousness around him, conscious of steadily increasing heat upon him, until the last of the slow-moving specks, absorbed one by one by the canyon's wall, disappeared from view. Then he turned his eyes elsewhere.

The men also turned away, but continued their excited talk. But even they after a time relapsed into silence. What it was all about Pat did not know. He knew it was something very serious, and suddenly fear came to him. He saw some of the men lie down as if to sleep, and he feared that they intended to remain here for ever, in this place absolutely dest.i.tute of herbage. But after a time, made sluggish by the att.i.tude of the men, he himself attempted to drowse. But the heat pulsating up off the rocks discouraged him, and he soon abandoned the attempt, standing motionless in the hot sun.

A change came over him. He took to brooding over his many discomforts--hunger pangs, loss of sleep, bothersome flies, the pain of his swollen ankles. As the day advanced his ankles swelled more, and grew worse, the flies became more troublesome, and his inner gnawings more p.r.o.nounced. So the time went on and he brooded through the still watches of the afternoon, through the soft stirrings of evening, on into night again. With the coming of night light breezes rose from the s.p.a.ces below to spur his fevered body into something of its wonted vigor. And the night brought also preparations among the men to journey on. This he welcomed, even more than the cooling zephyrs.

There was some delay. His master entered upon a dispute with the horseless man. The voices became excited and rose to vehement heights.

But presently they subsided when Pat himself, anxious to be active, sounded a note of protest. Yet the argument proved to his benefit.

Instead of mounting him behind his master, the odd man swung up behind another man on the sorrel. Then he was permitted to move forward, and as he approached the narrow defile he sounded another nicker, now of gratification.

The pa.s.s dropped almost sheer in places. As he descended, more than once he was compelled to slide on stiffened legs. In this at first he felt ecstatic danger thrills. But only at first. Soon he wearied of it, and he was glad when he struck the bottom, where, after being guided out of shadow and into broad moonlight, he found himself moving to the west in a deep canyon. With the other horses he burst into a canter, and continued at a canter hour after hour, following the winding and twisting canyon until daylight, with its shadows creeping away before him, revealed to his tired eyes a stretch of mesa ahead, dotted with inviting clumps of bunch-gra.s.s. Then of his own volition he came to a stop and fell to grazing. Soon all the horses were standing with mouths to earth, feeding eagerly.

The men, sitting for a time in quiet conversation, finally dismounted, laughing now and then, and casting amused glances toward the black horse.

Soon they mounted again to take the trail. Instead of riding with the other on the sorrel, the odd man swung up on Pat's back behind his master. But as Pat no longer suffered from hunger, he complacently accepted the return of the double load. Then all moved forward. Pat jogged out of the canyon, turning to the right on the desert, and moved rapidly north in the shadow of the hills. He held to his stride, and toward noon, rounding a giant ridge projecting into the desert from the hills, he saw ahead on his right, perhaps two miles distant across a basin, the mouth of another canyon. Evidently his master saw it also, and obviously it contained danger, for he jerked Pat down to a walk.

Almost instantly he knew that the danger was real, for the man, sounding a sharp command to the others, brought him to a full stop. Then followed an excited discussion, and, when it ended, Pat, gripped in vague uneasiness, found himself urged forward at top speed. Yet in a dim way he knew what was wanted of him. He flung himself into a long stride and dashed across the wide basin, across the mouth of the canyon, into the shadow of the hills again. Breathless, he slackened his pace with thirty excited horses around him, mad swirling clouds of dust all about, and before him the oppressive stillness of the desert. They were safely past the danger zone.

He pressed on at a slow canter. Ahead the mesa revealed numerous sand-dunes, large and small, rising into the monotonous skyline.

Plunging among them, he mounted some easily, others he skirted as easily, and once, to avoid an unusually large one, he dropped down into the bed of an arroyo, traveled along its dry course, and then clambered up on the desert. But it was wearying work, and, becoming ever more aware of his double load, he began to chafe with dissatisfaction. Yet he held to his gait, hopeful of better things--he was always hopeful of better things now--until he reached another dune, larger than any as yet encountered, when once more he broke out of his stride to circle its bottom. As he did so, of his own volition he checked himself. Dead ahead he saw horses scattered about, and beyond the horses, rising limply in the noon haze, a thin column of smoke. Also, he felt both his riders stiffen. Then on the midday hush rose the crack of firearms from the direction of the camp.

His master lifted a shrill voice. He felt a mighty pull at his head. He swung around like a flash. Then came the flaying of a rope and frantic urging of heels. He plunged among the surging horses, dancing and whirling excitedly, and out into the open beyond. He set his teeth grimly, and raced headlong to the south, galloping furiously, tearing blindly over the desert. He headed straight for the distant basin, straight for the mouth of the canyon, hurtling forward, struggling mightily under his double load. He did not know it, but he was speeding into a tragic crisis.

The others overtook him. They were carrying but single loads. But they did not pa.s.s him. He saw to that. He burst forward into even greater speed, clung to it grimly, forged into a position well in the lead. And he held this place--around him frenzied horses, frantic riders; behind him, to the distant rear, shot after shot echoing over the desert; before him the baking sands, shimmering heat-waves, sullen and silent.

He raced on, swinging up over dunes, dropping into hollows, speeding across flats, mounting over dunes again, on and on toward the basin and the mouth of the canyon--and protection.

But again disaster.

Suddenly, out of the canyon poured the cheerful notes of a bugle. On the vibrant wings of the echoes, streaming into the basin from the canyon, swept a body of flying hors.e.m.e.n. Instantly he checked himself. Then his master sounded a shrill outcry, swung his head around violently, and lashed him forward again. He hurtled headlong, dashing toward the distant ridge, the peninsula jutting out into the desert. Grimly he flung out along this new course. But he kept his eyes to the left. He saw the hors.e.m.e.n there also swerve, saw them spread out like a fan, and felt his interest kindle joyously. For this was a race! It was a race for that ridge! And he must win! He must do this thing, for instinctively he knew that beyond it lay safety. There he could flee to some haven, while cut off from it, cut off by these steady-riding men on his left, he must submit to wretched defeat. So he strained himself harder and burst into fresh speed, finding himself surprised that he could. In the thrill of it he forgot his double load, forgot the close-pressing horses, forgot irritating dust. On he galloped, racing forward with machine-like evenness--on his left the paralleling hors.e.m.e.n, to his rear yelling and shooting, on his right his own men and horses, and for them he felt he must do big things.

Suddenly the shooting in his rear ceased. Evidently these men had received some warning from the riders on his left. Then he awoke to another truth. The hors.e.m.e.n on his left were gaining. It troubled him, and he cast measuring eyes to the front. He saw that he was pursuing a shorter line to the ridge; he believed he still could reach it first. So again he strained on, whipping his legs into movement till they seemed about to snap. But the effort hurt him and he discovered that he was becoming woefully tired. Also, the double weight worried him. It had not become lighter with the miles, nor had he grown stronger. Yet he galloped on with thundering hoofs, the tranquil desert before him, the thud of carbines against leather to the left, behind him ominous silence. But he kept his eyes steadily to the left, and presently he awoke to something else there, something that roused him suddenly and in some way whipped his conscience. For now he saw a white figure amid the khaki, racing along with them--a part of them and yet no part of them--a familiar figure wearing a familiar bandage. This for a brief moment only. Then he took to measuring distances again; saw that the cavalrymen were holding to the course steadily, racing furiously as he himself was racing for the ridge. Would he win?

A shrill outcry from his master, and he found himself checked with a jerk. It was unexpected, sudden, and he reared. The movement shook off the second man. Dropping back upon all-fours, Pat awoke to the relief the loss of this load gave him. Grimly determining to hold to this relief, he dashed ahead, following the guidance of his master in yet another direction, hurtled away before the second man could mount again.

He found that he was speeding in a direction almost opposite from the ridge. He did not understand this. But his regret was not long lived.

Casting his eyes to his left in vague expectancy of seeing the familiar spot of white again, he saw only his own men and horses, and beyond them the smiling desert. Puzzled, he gazed to the right. Here he saw the cavalrymen, and though puzzled more, he yet kept on with all his power.

As he ran he suddenly awoke to the presence of a new body of hors.e.m.e.n on his distant left, a smaller band than the cavalrymen, men without uniforms, most of them hatless, all yelling. He remembered this yell, and now he understood. He was speeding toward the mouth of the canyon; had been turned completely around. And thus it was, he knew, that the hors.e.m.e.n once on his left were now on his right, and the madly yelling group at his rear was now on his left. He awoke to another realization.

This was a race again, a race with three new entrants now--all three making toward the canyon. Would he win?
