"Then go," cried Marianne, turning eagerly to Red Jim. "For heaven's sake, go at once! Forget Alcatraz—forget the mares—but start at once, Mr. Perris!"

Even a blind man might have guessed many things from the tremor of her voice. Lew Hervey saw enough to make his eyes contract to the brightness of a ferret's as he glanced from the girl to handsome Jim Perris. But the red-headed adventurer was quite blind, quite deaf. No matter how the thing had been done, he knew that the girl and the foreman were now both combined to drive him from the ranch, from Alcatraz. For a moment of blind anger he wanted to crush, kill, destroy. Then he turned on his heel and strode towards the arch which led into the patio.

"Mind you!" called Lew Hervey in warning. "It's on your own head, Perris. If you don't leave, I'll throw you off!"

Red Jim flashed about under the shade of the arch.

"Come get me, and be damned," he said.

And then he was gone. The cowpunchers, furious at this open defiance of them all, boiled out into the patio, growling.

"You see?" said Hervey to the girl. "He won't be satisfied till there's a killing!"

"Keep them back!" she pleaded. "Don't let them go, Mr. Hervey. Don't let them follow him!"

One sharp, short order from Hervey stopped the foremost as they ran for the entrance. In fact, not one of them was peculiarly keen to follow such a trail as this in the darkness. Breathless silence fell over the patio, and then they heard the departing beat of the hoofs of Red's horse. And the shock of every footfall struck home in the heart of Marianne and filled her with a great loneliness and terror. And then the noise of the gallop died away in the far-off night.

CHAPTER XVII
INVISIBLE DANGER

Alcatraz, cresting the hill, warned the mares with a snort. One by one the bays brought up their beautiful heads to attention but the grey, as was her custom in moments of crisis or indecision, trotted forward to the side of the leader and glanced over the rolling lands below. Her decision was instant and decisive. She shook her head and turning to the side, she started down the left slope at a trot. Alcatraz called her back with another snort. He knew, as well as she did, the meaning of that faint odor on the east wind: it was man, unmistakably the great enemy; but during five days that scent had hung steadily here and yet, over all the miles which he could survey there was no sign of a man nor any places where man could be concealed. There was not a tree; there was not a fallen log; there was not a stump; there was not a rock of such respectable dimensions that even a rabbit would dare to seek shelter behind it. Still, mysteriously, the scent of man was there.

Alcatraz stamped with impatience and when the grey whinnied he merely shook his head angrily in answer. It irritated him to have her always right, always cautious, and besides he felt somewhat shamed by the necessity of using her as a court of last appeal. To be sure, he was a keener judge of the sights and scents of the mountain desert than any of the half-bred mares but though he lived to fifty years he would never approach the stored wisdom, the uncanny acuteness of eye, ear, and nostril of the wild grey. Her view-point seemed, at times, that of the high-sailing buzzards, for she guessed, miles and miles away, what water-holes were dry and what "tanks" brimmed with water; what trails were broken by landslides since they had last been travelled and where new trails might be found or made; when it was wise to seek shelter because a sand-storm was brewing; where the grass grew thickest and most succulent on far-off hillsides; and so on and on the treasury of her knowledge could be delved in inexhaustibly.

On only one point did he feel that his cleverness might rival hers and that point was the most important of all—man the Great Destroyer. She knew him only from a distance whereas had not Alcatraz breathed that dreaded scent close at hand? Had he not on one unforgetable occasion felt the soft flesh turn to pulp beneath his stamping feet, and heard the breaking of bones? His nostrils distended at the memory and again he searched the lowlands.

No, there was not a shadow of a place where man might be concealed and that scent could be nothing but a snare and an illusion. To be sure there were other ways hardly less convenient to the waterhole, but why should he be turned from the easiest way day after day because of this unbodied warning? He started down the slope.

It brought the grey after him, neighing wildly, but though she circled around him at full speed time after time, he would not pause, and when she attempted to block him he raised his head and pushed her away with the resistless urge of breast and shoulders. At that she attempted no more forceful persuasion but fell in behind him, still pausing from time to time to send her mournfully persuasive whinny after the obdurate leader until even the bays, usually so blindly docile, grew alarmed and fell back to a huddled grouping half way between Alcatraz and the trailing grey. It touched his pride sharply, this division of their trust. Twice he slackened his lope and called to them to hasten and when they responded with only a faint-hearted trot he was forced to mask his impatience. Coming to a walk he cropped imaginary grasses from time to time and so induced the others to draw nearer.

It was slow work going down the hollow in this way, and hot work, too, but though he often glanced up yearningly towards the wooded hills beyond, he kept to his pretense of carelessness and so managed to hold the mares in a close-bunched group behind him. In the meantime the scent grew stronger, closer to the ground on that east wind. Time and again he raised his head and stared earnestly, but it was impossible for any living creature to stalk within hundreds of yards of him without being seen—whereas that scent spoke of one almost within leaping distance. Once it seemed to his excited imagination—as he lowered his head to sniff at a tuft of dead grasses—that he heard the sound of human breathing.

He snorted the foolish thought into nothingness and after a glance back to make sure that his companions followed, he resolutely stepped out into the very heart of the man-scent. So closely was that phantom located by the sense of smell that it seemed to Alcatraz he could see the exact spot on the hillside behind a small rock where the ghost must lie. Yet he disdained to flee from empty air and for all his beating heart he raised his head and walked sedately on. The danger spot was drifting past on his left when a squeal of fear from the wild grey far in the rear made Alcatraz leap sidewise with catlike suddenness.

Growing by magic from the sand behind the little rock the head and shoulders of a man appeared, his shadow pouring down the sun-whitened slope. In his hand he swung a rapidly lengthening loop of rope and as his arm went back it knocked off the fellow's hat and exposed a shock of red hair. So much Alcatraz saw while the paralysis of fear locked every joint for the tenth part of a second, and deeply as he dreaded the apparition itself he dreaded more the whipping circle of rope. For had he not seen the dead thing become alive and snakelike in the skilled hand of Manuel Cordova? The freezing terror relaxed; the sand crunched away under the drive of his rear hoofs as he flung himself forward—with firm footing to aid he would have slid from beneath the flying danger, but as it was he heard the live rope whisper in the air above his head.

He landed on stiff legs, checked his forward impetus and flung sidewise. On solid footing he would have dodged successfully; as it was the noose barely clipped past his ear.

As the rope touched his neck, it seemed to Alcatraz that every wound dealt him by the hand of man was suddenly aching and bleeding again, the skin along his flanks quivered where the spurs of Cordova had driven home time and again, and on shoulders and belly and hips there were burning stripes where the quirt had raised its wale. Most horrible of all, in his mouth came the taste of iron and his own blood where the Spanish bit had wrenched his jaws apart. Out of the old days he might have remembered the first and bitterest lesson—that it is folly to pull against a rope—but now he saw nothing save the fleeing forms of the seven mares and his own freedom vanishing with them. In his mid-leap the lariat hummed taut, sank in a burning circle into the flesh at the base of his neck, and he was flung to the ground. No man's power could have stopped him so short; the cunning enemy had turned a half-hitch around the top of that deep-rooted rock.

He landed, not inert, but shocked out of hysteria into all his old cunning—that wily savagery which had kept Cordova in fear, ten-fold more terrible since the free life had clothed him with his full strength. The very impetus of his fall he used to help him whirl to his feet, and as he rose he knew what he must do. To struggle against the tools of man was always madness and brought only pain as a result; like a good general he determined to end the battle by getting at the root of the enemy's fire, and wheeling on his hind legs he charged Red Perris.

The first leap revealed the mystery of the man's appearance. Behind this rock, which was barely sufficient shelter for his head, he had excavated a pit sufficient to shelter his crouching body and the sand which he removed for this purpose had been spread evenly over the slope so that no suspicion might be created in the most watchful eye. He had sprung from his concealment and was now working to loosen the half-hitch from the rock. As the knot came free Alcatraz was turning and now Perris faced the charge with the rope caught in his hand. What could he do? There was only one thing, and the stallion saw the heavy revolver bared and levelled at him, a flickering bit of metal. He knew well what it meant but there was no hope save to rush on; another stride and he would be on that frail creature, tearing with his teeth and crushing with his hoofs. And then a miracle happened. The revolver was flung aside, a gleaming arc and a splash of sand where it struck; Red Perris preferred to risk his life rather than end the battle before it was well begun with a bullet. He crouched over the rope as though he had braced himself to meet the shock of the charging stallion. But that was not his purpose. As the stallion rushed on him he darted to one side and the fore hoof with which Alcatraz struck merely slashed his shirt down the back.

A feint had saved him, but Alcatraz was no bull to charge blindly twice. He checked himself so abruptly that he knocked up a shower of sand, and he turned savagely out of that dust-cloud to end the struggle. Yet this small, mad creature stood his ground, showed no inclination to flee. With the rope he was doing strange things, making it spin in swift spirals, close to the ground. Let him do what he would, his days were ended. Alcatraz bared his teeth, laid back his ears, and lunged again. Another miracle! As his forefeet struck the ground in the midst of one of those wide circles of rope, the red-headed man lunged back, the circle jumped like a living thing and coiled itself around both forefeet, between fetlock and hoof. When he attempted the next leap his front legs crumbled beneath him. At the very feet of Red Perris he plunged into the sand.

Once more he whirled to regain his lost footing, but as he turned on his back the rope twisted and whispered above him; the off hind leg was noosed, and then the near one—Alcatraz lay on his side straining and snorting but utterly helpless.

Of a sudden he ceased all struggle. About neck and all four hoofs was the burning grip of the rope, so bitterly familiar, and man had once again enslaved him. Alcatraz relaxed. Presently there would come a swift volley of curses, then the whir and cut of the whip—no, for a great occasion such as this the man would choose a large and durable club and beat him across the ribs. Why not? Even as he had served Cordova this man of the flaming hair would now serve him. He was very like Cordova in one thing. He did not hurry, but first picked up his revolver and replaced it in its holster, having blown the sand from the mechanism as well as he could. Then he put on his fallen hat and stood back with his hands dropped on his hips and eyed the captive. For the first time he spoke, and Alcatraz shuddered at the sound of a voice well-nigh as smooth as that of Cordova, with the same well-known ring of fierce exultation.

"God A'mighty, God A'mighty! They can't be no hoss like this! Jim, you're dreaming. Rub your fool eyes and wake up!"

He began to walk in a circle about his victim, and Alcatraz shuddered when the conqueror came behind him. That had been Cordova's way—to come to a place where he could not be seen and then strike cruelly and by surprise. To his unspeakable astonishment, Perris presently leaned over him—and then deliberately sat down on the shoulder of the chestnut. Two thoughts flashed through the mind of the stallion; he might heave himself over by a convulsive effort and attempt to crush this insolent devil; or he might jerk his head around and catch Perris with his teeth. A third and better thought, however, immediately followed—that bound as he was he would have little chance to reach this elusive will-o'-the-wisp. He could not repress a quiver of horror and anger, but beyond that he did not stir.

Other liberties were being taken; Cordova in his maddest moments would not have dared so much. Down the long muscles of his shoulder and upper foreleg went curious and gently prying finger-tips, and where they passed a tingling sensation followed, not altogether unpleasant. Again beginning on his neck the hand trailed down beneath his mane and at the same time the voice was murmuring: "Oh beauty! Oh beauty!"

The heart of Alcatraz swelled. He had felt his first caress.

CHAPTER XVIII
VICTORY

Not that he recognized it as such but the touch was a pleasure and the quiet voice passed into his mind with a mild and soothing influence that made the wide freedom of the mountain-desert seem a worthless thing. The companionship of the mares was a bodiless nothing compared with the hope of feeling that hand again, hearing that voice, and knowing that all troubles, all worries were ended for ever. Like the stout Odysseus of many devices Alcatraz scorned the ways of the lotus eaters; for well he knew how Cordova had often lured him to perfect trust with the magic of man's voice, only to waken him from the dream of peace with the sting of a blacksnake. This red-headed man, so soft of hand, so pleasant of voice, was for those very reasons the more to be suspected. The chestnut bided his time; presently the torment would begin.

The calm voice was proceeding: "Old sport, you and me are going to stage a sure enough scrap right here and now. Speaking personal, I'd like to take off the rope and go at you man to man with no saddle to help me out. But if I did that I wouldn't have a ghost of a show. I'll saddle you, right enough, but I'll ride you without spurs, and I'll put a straight bit in your mouth—damn the Mexican soul of Cordova, I see where he's sawed your mouth pretty near in two with his Spanish contraptions! Without a quirt or spurs or a curb to choke you down, you and me'll put on a square fight, so help me God! Because I think I can beat you, old hoss. Here goes!"

The stallion listened to the soothing murmur, listened and waited, and sure enough he had not long to stay in expectation. For Perris went to the hole behind the rock and presently returned carrying that flapping, creaking instrument of torture—a saddle.

To all that followed—the blind-folding, the bridling, the jerk which urged him to his feet, the saddling,—Alcatraz submitted with the most perfect docility. He understood now that he was to have a chance to fight for his liberty on terms of equality and his confidence grew. In the old days that consummate horseman, Manuel Cordova, had only been able to keep his seat by underfeeding Alcatraz to the point of exhaustion but now, from withers to fetlock joint, the chestnut was conscious of a mighty harmony of muscles and reserves of energy. The wiles which he had learned in many a struggle with the Mexican were not forgotten and the tricks which had so often nearly unseated the old master could now be executed with threefold energy. In the meantime he waited quietly, assuming an air of the most perfect meekness, with the toe of one hind foot pointed so that he sagged wearily on that side, and with his head lowered in all the appearance of mild subjection.

The cinches bit deep into his flesh. He tasted that horror of iron in his mouth, with this great distinction: that whereas the bits of Manuel Cordova had been heavy instruments of torture this was a light thing, smooth and straight and without the wheel of spikes. The crisis was coming. He felt the weight of the rider fall on the left stirrup, the reins were gathered, then Perris swung lightly into the saddle and leaning, snatched the blindfold from the eyes of the stallion.

One instant Alcatraz waited for the sting of the spurs, the resounding crack of the heavy quirt, the voice of the rider raised in curses; but all was silence. The very feel of the man in the saddle was different, not so much in poundage as in a certain exquisite balance which he maintained but the pause lasted no longer than a second after the welcome daylight flashed on the eyes of Alcatraz. Fear was a spur to him, fear of the unknown. He would have veritably welcomed the brutalities of Cordova simply because they were familiar—but this silent and clinging burden? He flung himself high in the air, snapped up his back, shook himself in mid-leap, and landed with every leg stiff. But a violence which would have hurled another man to the ground left Perris laughing. And were beasts understood, that laughter was a shameful mockery!

Alcatraz thrust out his head. In vain Perris tugged at the reins. The lack of curb gave him no pry on the jaw of the chestnut and sheer strength against strength he was a child on a giant. The strips of leather burned through his fingers and the first great point of the battle was decided in favor of the horse: he had the bit in his teeth. It was a vital advantage for, as every one knows who has struggled with a pitching horse, it cannot buck with abandon while its chin is tucked back against its breast; only when the head is stretched out and the nose close to the ground can a bucking horse double back and forth to the full of his agility, twisting and turning and snapping as an "educated" bucker knows how.

And Alcatraz knew, none so well! The deep exclamation of dismay from the rider was sweetest music to his malicious ears, and, in sheer joy of action, he rushed down the hollow at full speed, bucking "straight" and with never a trick attempted, but when the first ecstasy cleared from his brain he found that Perris was still with him, riding light as a creature of mist rather than a solid mass of bone and muscle—in place of jerking and straining and wrenching, in place of plying the quirt or clinging with the tearing spurs, he was riding "straight up" and obeying every rule of that unwritten code which prescribes the manner in which a gentleman cowpuncher shall combat with his horse for superiority. Again that thrill of terror of the unknown passed through the stallion; could this apparently weaponless enemy cling to him in spite of his best efforts? He would see, and that very shortly. Without going through the intermediate stages by which the usual educated bronco rises to a climax of his efforts, Alcatraz began at once that most dreaded of all forms of bucking—sun-fishing. The wooded hills were close now and the ground beneath him was firm underfoot assuring him full use of all his agility and strength. His motion was like that of a breaking comber. First he hurled himself into the air, then pitched sharply down and landed on one stiffened foreleg—the jar being followed by the deadly whiplash snap to the side as he slumped over. Then again driven into the air by the impulse of those powerful hind legs, he landed on the alternate foreleg and snapped his rider in the opposite direction—a blow on the base of the brain and another immediately following on the side.

Underfed mustangs have killed men by this maneuver, repeated without end. Alcatraz was no starveling mongrel, but to the fierceness of a wild horse and the tireless durability of a mustang he united the subtlety which he had gained in his long battle with the Mexican and above all this, his was the pride of one who had already conquered man. His fierce assault began to produce results.

He saw Red Perris sway drunkenly at every shock; his head seemed to swing on a pivot from side to side under that fearful jolting—his mouth was ajar, his eyes staring, a fearful mask of a face; yet he clung in place. When he was stunned, instinct still kept his feet in the stirrups and taught him to give lightly to every jar. He fought hard but in time even Red Perris must collapse.

But could the attack be sustained indefinitely? Grim as were results of sun-fishing on the rider, they were hardly less vitiating for the horse. The forelegs of Alcatraz began to grow numb below the shoulder; his knees bowed and refused to give the shock its primal snap; to the very withers he was an increasing ache. He must vary the attack. As soon as that idea came, he reared and flung himself back to the earth.

He heard a sharp exclamation from the rider—he felt the tug as the right foot of Perris hung in the stirrup, then the stunning impact on the ground. To make sure of his prey he whirled himself to the left, but even so his striking feet did not reach the Great Enemy. Perris had freed himself in the last fraction of a second and pitching headlong from the saddle he rolled over and over in the dirt, safe. That fall opened a new hope to Alcatraz. Had he possessed his full measure of agility he would have gained his feet and rushed the man, but the long struggle had taken the edge from his activity and as he lunged up he saw Perris, springing almost on all-fours, animal-like, leap through the air and his weight struck home in the saddle.

Quick, now, before the Enemy gained a secure hold, before that reaching foot attained the other stirrup, before the proper balance was struck! Up in the air went the chestnut—down on one stiff foreleg and with a great swelling of the heart he felt the rider slump far to one side, clinging with one leg from the saddle, one hand wrapped in the flying mane. Now victory with a last effort! Again he leaped high and again struck stiffly on the opposite foreleg; but alas! that very upward bound swung Perris to the erect, and with incredible and catlike speed he slipped into the saddle. He received the shock with both feet lodged again in the supporting stirrups.

The frenzy of disappointment gave Alcatraz renewed energy. It was not sun-fishing now, but fence-rowing, cross-bucking, flinging himself to the earth again and again, racing a little distance and stopping on braced legs, sun-fishing to end the programme. As he fought he watched results. It was as though invisible fists were crashing against the head and body of the unfortunate rider. From nose and ears and gaping mouth the blood trickled; his eyes were blurs of red; his head rolled hideously on his shoulders. Ten times he was saved by a hair's-breadth from a fall; ten times he righted himself again and a strange and bubbling voice jerked out defiance to the horse.

"Buck—damn you!—go it, you devil—I'll—beat—you still! I'll break you—I'll—make you come—when I whistle—I'll make you—a—lady's hoss!"'

Consuming terror was in the stallion and the fear that, incredible as it seemed, he was being beaten by a man who did not use man's favorite weapon—pain. No, not once had the cruel spurs clung in his flanks, or the quirt whirred and fallen; not once, above all, had his mouth been torn and his jaw nearly broken by the wrenching of a curb. It came vaguely into the brutes' mind that there was something to be more dreaded than either bit, spur, or whip, and that was the controlling mind which spoke behind the voice of Perris, which was telegraphed again and again down the taut reins. That fear as much as the labor drained his vigor.

His knees buckled now. He could no longer sunfish. He could not even buck straight with the bone-breaking energy. He was nearly done, with a tell-tale wheeze in his lungs, with blood pressure making his eyes start well-nigh from his head, and a bloody froth choking him. Red Perris also was in the last stage of exhaustion—one true pitch would have hurled him limp from his seat—yet, with his body numb from head to toe, he managed to keep his place by using that last and greatest strength of feeble man—power of will. Alcatraz, coming at last to a beaten stop, looked about him for help.

There was nothing to aid, nothing save the murmur of the wind in the trees just before him. Suddenly his ears pricked with new hope and he shut out the weak voice which murmured huskily: "I've got you now. I've got you, Alcatraz. I've all by myself—no whip,—no spur—no leather pulling—I've rode straight up and–"

Alcatraz lunged out into a rickety gallop. Only new hope sustained him as he headed straight for the trees.

Even the dazed brain of Perris understood. With all his force he wrenched at the bit—it was hopelessly lodged in the teeth of the stallion—and then he groaned in despair and a moment later swayed forward to avoid a bough brushing close overhead.

There were other branches ahead. On galloped Alcatraz, heading cunningly beneath the boughs until he was stopped by a shock that dropped him staggering to his knees. The pommel had struck a branch—and Red Perris was still in place.

Once more the chestnut started, reeling heavily in his lope. This time, to avoid the coming peril, the rider slipped far to one side and Alcatraz veered swiftly towards a neighboring tree trunk. Too late Red Perris saw the danger and strove to drag himself back into the saddle, but his numbed muscles refused to act and Alcatraz felt the burden torn from his back, felt a dangling foot tug at the left stirrup—then he was free.

So utter was his exhaustion that in checking himself he nearly fell, but he turned to look at the mischief he had worked.

The man lay on his back with his arms flung out cross-wise. From a gash in his forehead the blood streamed across his face. His legs were twisted oddly together. His eyes were closed. From head to foot the stallion sniffed that limp body, then raised a forehoof to strike; with one blow he could smash the face to a smear of red as he had smashed Manuel Cordova the great day long before.

The hoof fell, was checked, and wondering at himself Alcatraz found that his blow had not struck home. What was it that restrained him? It seemed to the conqueror that he felt again the gentle finger-tips which had worked down the muscles of his shoulder and trailed down his neck. More than that, he heard the smooth murmur of the man's voice like a kindly ghost beside him. He dreaded Red Perris still, but hate the fallen rider he could not. Presently a loud rushing of the wind among the branches above made him turn and in a panic he left the forest at a shambling trot.
