She had done her best and she had failed. What reason was there for her to remain? Should she endure witnessing in reality the horror which she had pictured so vividly in imagination? A flash of fire! The fall of a careening figure to the earth! Leddy's grin of satisfaction! The rejoicing of his clan of spectators over the exploit, while youth which sang airs to the beat of a pony's hoofs and knew the worship of the Eternal Painter lay dead!

What reason to remain except to punish herself! She would go. But something banished reason. She was held in the leash of suspense, staring with clearness of vision in one second; staring into a mist the next; while the coming and going of Ignacio's breaths between his teeth was the only sound in her ears.

"SeÑor Don't Care of the Big Spurs will win!" he whispered.

"He will?" she repeated, like one marvelling, in the tautness of every nerve and muscle, that she had the power of speech.

She peered into Ignacio's face. Its Indian impassivity was gone. His lips were twitching; his eyes were burning points between half-closed lids.

"Why?" she asked. "How?"

"I know. I watch him. I have seen a mountain lion asleep in a tree. His paw is like velvet. He smiles. There seems no fight in him. I know. There is a devil, a big devil, in SeÑor Don't Care. It sleeps so much it very terrible when it awakes. And Pete Leddy—he is all the time awake; all the time too ready. Something in him will make his arm shake when the moment to shoot comes and something in SeÑor Don't Care—his devil—will make his arm steady."

Could Ignacio be right? Did Jack really know how to shoot? Was he confident of the outcome? Were his smiles the mask of a conviction that he was to kill and not to be killed? After all, had his attitude toward her been merely acting? Had she undergone this humiliation as the fish on the line of the mischievous play of one who had stopped over a train in order to do murder? No! If he were capable of such guile he knew that Leddy could shoot well and that twenty yards was a deadly range for a good shot. He was taking a chance and the devil in him was laughing at the chance, while it laughed at her for thinking that he was an innocent going to slaughter in expression of a capricious sense of chivalry.

"He will win—he will win if Leddy plays fair!" Ignacio repeated.

Now she was telling herself that it was solely for the sake of her conscience that she wanted to see SeÑor Don't Care survive; solely for the sake of her conscience that she wanted to see him go aboard the train safe. After that, she could forget ever having owed this trifler the feeling of gratitude for a favor done. Literally, he must live in order to be a dead and unremembered incident of her existence.

And Jack was back at his station, with the bright sunlight heightening the colors of his play cowboy attire, his weight on the ball of his right foot thrown well ahead of the other, his head up, but the whole effect languid, even deferential. He seemed about to take off his hat to the joyous sky of a fair day in May. His shadow expressed the same feeling as his pose, that of tranquil youth with its eyes on the horizon. Leddy had the peculiar slouch of the desperado, which is associated with the spread of pioneering civilization by the raucous criers of red-blooded individualism. If Jack's bearing was amateurish, then Pete's was professional in its threatening pose; and his shadow, like himself, had an unrelieved hardness of outline.

Both drew their guns from their holsters and lowered them till the barrels lay even with the trousers seams. They awaited the word to fire which Bill Lang, who stood at an angle equidistant from the two men, was to give.

"Wait!" Jack called, in a tone which indicated that something had recurred to him. Then a half laugh from him fell on the brilliant, shining, hard silence with something of the sound of a pebble slipping over glare ice.

"Leddy, it has just occurred to me that we are both foolish—honestly, we are!" he said. "The idea when Arizona is so sparsely settled of our starting out to depopulate it in such a premeditated manner on such a beautiful morning, and all because I was such an inept whistler! Why, if I had realized what a perfectly bad whistler I was I would never have whistled again. If my whistle hurt your feelings I am sorry, and I—"

"No, you don't!" yelled Leddy. "I've waited long enough! It's fight, you—"

"Oh, all right! You are so emphatic," Jack answered. His voice was still pleasant, but shot with something metallic. The very shadow of him seemed to stiffen with the stiffening of his muscles.

"Ready!" called Bill Lang.

The ruling passion that had carved six notches on his gun-handle overwhelmed Pete Leddy. At least, let us give him the benefit of the doubt and say that this and not calculation was responsible for his action. Before the word for preparation was free of Lang's lips, and without waiting for the word to fire, his revolver came up in a swift quarter-circle. He was sure of his aim at that range with a ready draw. Again and again he had thus hit his target in practice and six times he had winged his man by such agile promptness.

With the flash from the muzzle all the members of the gallery rose on hands and knees. They were as sure that there was to be a seventh notch as of their identity. There was no question in their minds but Pete had played a smart trick. They had known from the first that he would win. And the proof of it was in the sudden, uncontrollable movement of the adversary.

Jack whirled half round. He was falling. But even as he fell he was still facing his adversary. He plunged forward unsteadily and came to rest on his left elbow. A trickle of blood showed on the chap of his left leg, which had tightened as his knee twisted under him. Leddy's rage had been so hot that for once his trigger finger had been too quick. He had aimed too low. But he was sure that he had done for his man and he looked triumphantly toward the gallery gods whose hero he was. They had now risen to their feet. In answer to their congratulations he waved his left hand, palm out, in salutation. His gun-hand had dropped back to his trousers seam.

Even as it dropped, Jack's revolver had risen, his own gun-hand steadied in the palm of his left hand, which had an elbow in the sand for a rest. Victor and spectators, in their preoccupation with the relief and elation of a drama finished, had their first warning of what was to come in a voice that did not seem like the voice of the tenderfoot as they had heard it, but of another man. And Leddy was looking at a black hole in a rim of steel which, though twenty yards away, seemed hot against his forehead, while he turned cold.

"Now, Pete Leddy, do not move a muscle!" Jack told him. "Pete Leddy, you did not play my way. I still have a shot due, and I am going to kill you!"

Jack's face seemed never to have worn a smile. It was all chin, and thin, tightly-pressed lips, and solid, straight nose, bronze and unyielding.

"And I am going to kill you!"

This was surely the devil of Ignacio's imagery speaking in him—a cold, passionless, gray-eyed devil. Though they had never seen him shoot, everybody felt now that he could shoot with deadly accuracy and that there was no play cowboy in his present mood. He had the bead of death on Leddy and he would fire with the first flicker of resistance. His call seemed to have sunk the feet of everyone beneath the sand to bed-rock and riveted them there. Lang and the two seconds were as motionless as statues.

Mary recalled Leddy's leer at her on the pass, with its intent of something more horrible than murder. Savagery rose in her heart. It was right that he should be killed. He deserved his fate. But no sooner was the savagery born—born, she felt, of the very hypnosis of that carved face—than she cast it out shudderingly in the realization that she had wished the death of a fellow human being! She looked away from Jack; and then it occurred to her that he must be bleeding. He was again a companion of the trail, his strength ebbing away. Her impulse was retarded by no fear of the gallery now. It brought her to her feet.

"But first drop your revolver!" she heard Jack call, as she ran.

She saw it fall from Leddy's trembling hand, as a dead leaf goes free of a breeze-shaken limb. All the fight was out of him. The courage of six notches was not the courage to accept in stoicism the penalty of foul play. And that black rim was burning his forehead.

"Galway, you have a gun?" Jack asked.

"Yes," Galway answered, mechanically. His presence of mind, which had been so sure in the store, was somewhat shaken. He had seen men killed, but never in such deliberate fashion.

"Take it out'"

There was a quality in the command like frosty madness, which one instinctively obeyed. The half-prostrate figure of the tenderfoot seemed to dominate everything—men, earth, and air.

Mary had a glimpse of Galway drawing an automatic pistol from his pocket when she dropped at Jack's side. She knew that Jack had not heard or seen her approach. All his will was flowing out along a pistol's sight, even as his blood was flowing out on the sand in a broadening circle of red.

It was well that she had come. Her fingers were splashed as she felt for the artery, which she closed by leaning her whole weight on the thumb.

Ignacio had followed her and immediately after him came Firio, who had been startled in his breakfast preparations by the sound of a shot and had set out to investigate its cause. He was as changed as his master; a twitching, fierce being, glaring at her and at the wound and then prolongedly and watchfully at Pete Leddy.

"Can you shoot to kill?" Jack asked Galway, in a piercing summons.

"Yes," drawled Galway.

"Then up with your gun—quick! There! A bead on Ropey Smith!"

Galway had the bead before Ropey could protest.

"Give Ropey ten seconds to drop his gun or we will care for him at the same time as Pete'" Jack concluded.

Ropey did not wait the ten seconds. He was over-prompt for the same reasons of temperament that made Pete Leddy prefer his own way of fighting.

"I take it that we can count on the neutrality of our spectators. They cannot be interested in the success of either side," Jack observed, with dry humor, but still methodically. "All they ask is a spectacle."

"Yes, you bet!" came a voice from the gallery, undisguisedly eager to concur.

"Now, Pete and Ropey," Jack began, and broke off.

There was a poignant silence that waited on the processes of his mind. Not only was there no sound, but to Mary there seemed no movement anywhere in the world, except the pulse of the artery trying to drive its flood past the barrier of her thumb. Jack kept his bead unremittingly on Pete. It was Firio who broke the silence.

"Kill him! He is bad! He hates you!" said Firio.

"SÍ, sÍ! If you do not kill him now, you must some time," said Ignacio.

Mary felt that even if Jack heard them he would not let their advice influence him. On the bank before she had hastened to him a strange and awful visitor in her heart had wished for Leddy's death. Now she wished for him to go away unharmed. She wished it in the name of her own responsibility for all that had happened. Yet her tongue had no urging word to offer. She waited in a supernatural and dreadful curiosity on Jack's decision. It was as if he were to answer one more question in explanation of the mystery of his nature. Could he deliberately shoot down an unarmed man? Was he that hard?

"I am thinking just how to deal with you, Pete and Ropey," Jack proceeded. "As I understand it, you have not been very useful citizens of Little Rivers. You can live under one condition—that you leave town and never return armed. Half a minute to decide!"

"I'll go!" said Pete.

"I'll go!" said Ropey.

"And keep your words?"

"Yes!" they assented.

But neither moved. The fact that Jack had not yet lowered his revolver made them cautious. They were obviously over-anxious to play safe to the last.

"Then go!" called Jack.

Pete and Ropey slouched away, leaving behind Ropey's gun, which was unimportant as it had only one notch, and Pete's precious companion of many campaigns with its six notches, lying on the sand.

"And, gentlemen," Jack called to the spectators, "our little entertainment is over now. I am afraid that you will be late for breakfast."

Apparently it came as a real inspiration to all at once that they might be, for they began to withdraw with a celerity that was amazingly spontaneous. Their heads disappeared below the skyline and only the actors were left. Pete and Ropey—Bill Lang following—walked away along the bed of the arroyo, instead of going over the bank. Pete paused when he was out of range. The old threat was again in his pose.

"I'm not through with you, yet!" he called.

"Why, I hope you are!" Jack answered.

He let his revolver fall with a convulsion of weakness. Mary wondered if he were going to faint. She wondered if she herself were not going to faint, in a giddy second, while the red spot on the sand shaped itself in revolving grotesquery. But the consciousness that she must not lift her weight from the artery was a centering idea to keep her faculties in some sort of equilibrium.

He was looking around at her, she knew. Now she must see his face after this transformation in him which had made her fears of his competency silly imaginings; after she had linked her name with his in an overwhelming village sensation. She was stricken by unanalyzable emotions and by a horror of her nearness to him, her contact with his very blood, and his power. She was conscious of a glimpse of his turning profile, still transfixed with the cool purpose of action. Then they were gazing full at each other, eyes into eyes, directly, questioningly. He was smiling as he had on the pass; as he had when he stood with his arms full of mail waiting for the signal to deposit his load. His devil had slipped back into his inner being.

He spoke first, and in the voice that went with his vaguest mood; the voice in which he had described his escape from the dinosaur whose scales had become wedged in the defile at the critical moment.

"You have a strong thumb and it must be tired, as well as all bluggy," he said, falling into a childhood symbol for taking the whole affair in play.

Could he be the same man who had said, "I am going to kill you!" so relentlessly? He had eased the situation with the ready gift he had for easing situations; but, at the same time, he had made those unanalyzable emotions more complex, though they were swept into the background for the moment. He glanced down at his leg with comprehending surprise.

"Now, certainly, you are free of all responsibility," he added. "You kept the strength in me to escape the fate you feared. Jim Galway will make a tourniquet and relieve you."

The first available thing for tightening the tourniquet was the barrel of Pete Leddy's gun and the first suggestion for material came from her. It was the sash of her gown, which Galway knotted with his strong, sunburned fingers.

When she could lift her numbed thumb from its task and rose to her feet she had a feeling of relief, as if she were free of magnetic bonds and uncanny personal proximity. The incident was closed—surely closed. She was breathing a prayer of thanks when a remark from Galway to Jack brought back her apprehension.

"I guess you will have to postpone catching to-day's train," he said.

Certainly, Jack must remain until his wound had healed and his strength had returned. And where would he go? He could not camp out on the desert. As Jasper Ewold had the most commodious bungalow it seemed natural that any wounded stranger should be taken there. The idea chilled her as an insupportable intrusion. Jack hesitated a moment. He was evidently considering whether he could not still keep to his programme.

"Yes, Jim, I'm afraid I shall have to ask you for a cot for a few days," he said, finally.

Again he had the right thought at the right moment. Had he surmised what was passing in her mind?

"Seeing that you've got Pete Leddy out of town, I should say that you were fairly entitled to a whole bed," Jim drawled. "These two Indians here can make a hustle to get some kind of a litter."

Now she could go. That was her one crying thought: She could go! And again he came to her rescue with his smiling considerateness.

"You have missed your breakfast, I'll warrant," he said to her. "Please don't wait. You were so brave and cool about it all, and—I—" A faint tide of color rose to his cheeks, which had been pale from loss of blood. For once he seemed unable to find a word.

Mary denied him any assistance in his embarrassment.

"Yes," she answered, almost bluntly. Then she added an excuse: "And you should have a doctor at once. I will send him."

She did not look at Jack again, but hastened away. When she was over the bank of the arroyo out of sight she put her fingers to her temples in strong pressure. That pulse made her think of another, which had been under her thumb, and she withdrew her fingers quickly.

"It is the sun! I have no hat," she said to herself, "and I didn't sleep well."
