The black head of Barry, the brown head of Randall Byrne, the golden head of Kate Cumberland, were all bowed around the limp body of Black Bart. Buck Daniels, still gasping for breath, stood reeling nearby.

"Let me attempt to resuscitate the animal," offered the doctor.

He was met by a blank look from Barry. The hair of the man was scorched, his skin was blistered and burned. Only his hands remained uninjured, and these continued to move over the body of the great dog. Kate Cumberland was on her knees over the brute.

"Is it fatal, Dan?" she asked. "Is there no hope for Bart?"

There was no answer from Barry, and she attempted to raise the fallen, lifeless head of the animal; but instantly a strong arm darted out and brushed her hands away. Those hands fell idly at her sides and her head went back as though she had been struck across the face. She found herself looking up into the angry eyes of Randall Byrne. He reached down and raised her to her feet; there was no colour in her face, no life in her limbs.

"There's nothing more to be done here, apparently," said the doctor coldly. "Suppose we take your father and go back to the house."

She made neither assent nor dissent. Dan Barry had finished a swift, deft bandage and stopped the bleeding of the dog's wounds. Now he raised his head and his glance slipped rapidly over the faces of the doctor and the girl and rested on Buck Daniels. There was no flash of kindly thanks, no word of recognition. His right hand raised to his cheek, and rested there, and in his eyes came that flare of yellow hate. Buck Daniels shrank back until he was lost in the crowd. Then he turned and stumbled back towards the house.

Instantly, Barry began to work at expanding and depressing the lungs of the huge animal as he might have worked to bring a man back to life.

"Watch him!" whispered the doctor to Kate Cumberland. "He is closer to that dog—that wolf, it looks like—than he has ever been to any human being!"

She would not answer, but she turned her head quickly away from the man and his beast.

"Are you afraid to watch?" challenged Byrne, for his anger at Barry's blunt refusals still made his blood hot. "When your father lay at death's door was he half so anxious as he is now? Did he work so hard, by half? See how his eyes are fixed on the muzzle of the beast as if he were studying a human face!"

"No, no!" breathed the girl.

"I fell you, look!" commanded the doctor. "For there's the solution of the mystery. No mystery at all. Barry is simply a man who is closer akin to the brute forces in nature. See! By the eternal heavens, he's dragging that beast—that dumb beast—back from the door of death!"

Barry had ceased his rapid manipulations, and turned the big dog back upon its side. Now the eyes of Black Bart opened, and winked shut again. Now the master kneeled at the head of the beast and took the scarred, shaggy head between his hands.

"Bart!" he commanded.

Not a stir in the long, black body. The stallion edged a pace closer, dropped his velvet muzzle, and whinnied softly at the very ear of the dog. Still, there was not an answering quiver.

"Bart!" called the man again, and there was a ring of wild grief—of fear—in his cry.

"Do you hear?" said Byrne savagely, at the ear of the girl. "Did you ever use such a tone with a human being? Ever?"

"Take me away!" she murmured. "I'm sick—sick at heart. Take me away!"

Indeed, she was scarcely sure of her poise, and tottered where she stood. Doctor Byrne slipped his arm about her and led her away, supporting half her weight. They went slowly, by small, soft steps, towards the house, and before they reached it, he knew that she was weeping. But if there was sadness in Byrne, there was also a great joy. He was afire, for there is a flamelike quality in hope. Loss of blood and the stifling smoke, rather than a mortal injury or the touch of fire, had brought Black Bart close to death, but now that his breathing was restored, and almost normal, he gained rapidly. One instant he lingered on the border between life and death; the next, the brute's eyes opened and glittered with dim recognition up towards Dan, and he licked the hand which supported his head. At Dan's direction, a blanket was brought, and after Dan had lifted Black Bart upon it, four men raised the corners of the blanket and carried the burden towards the house. One of the cowpunchers went ahead bearing the light. This was the sight which Doctor Byrne and Kate Cumberland saw from the veranda of the ranch-house as they turned and looked back before going in.

"A funeral procession," suggested the doctor.

"No," she answered positively. "If Black Bart were dead, Dan wouldn't allow any hands save his own to touch the body. No, Black Bart is alive! Yet, it's impossible."

The word "impossible," however, was gradually dropping from the vocabulary of Randall Byrne. True, the wolf-dog had seemed dead past recovery and across the eyes of Byrne came a vision of the dead rising from their graves. Yet he merely shook his head and said nothing.

"Ah!" she broke in. "Look!"

The procession drew nearer, heading towards the back of the big house, and now they saw that Dan Barry walked beside the body of Black Bart, a smile on his lifted face. They disappeared behind the back of the house.

Byrne heard the girl murmuring, more to herself than to him: "Once he was like that all the time."

"Like what?" he asked bluntly.

She paused, and then her hand dropped lightly on his arm. He could not see more than a vague outline of her in the night, only the dull glimmer of her face as she turned her head, and the faint whiteness of her hand.

"Let's say good-night," she answered, at length. "Our little worlds have toppled about our heads to-night—all your theories, it seems, and, God knows, all that I have hoped. Why should we stay here and make ourselves miserable by talk?"

"But because we have failed," he said steadily, "is that a reason we should creep off and brood over our failure in silence? No, let's talk it out, man to man."

"You have a fine courage," said the girl. "But what is there we can say?"

He answered: "For my part, I am not so miserable as you think. For I feel as if this night had driven us closer together, you see; and I've caught a perspective on everything that has happened here."

"Tell me what you know."

"Only what I think I know. It may be painful to hear."

"I'm very used to pain."

"Well, a moment ago, when Barry was walking beside his dog, smiling, you murmured that he once was like that always. It gave me light. So I'd say that there was a time when Dan Barry lived here with you and your father. Am I right?"

"Yes, for years and years."

"And in those times he was not greatly different from other men. Not on the surface."

"No."

"You came to be very fond of him."

"We were to marry," answered Kate Cumberland, and Byrne winced.

He went on: "Then something happened—suddenly—that took him away from you, and you did not see him again until to-night. Am I right?"

"Yes. I thought you must have heard the story—from the outside. I'll tell you the truth. My father found Dan Barry wandering across the hills years ago. He was riding home over the range and he heard a strange and beautiful whistling, and when he looked up he saw on the western ridge, walking against the sky, a tattered figure of a boy. He rode up and asked the boy his name. He learned it was Dan Barry—Whistling Dan, he was called. But the boy could not, or would not, tell how he came to be there in the middle of the range without a horse. He merely said that he came from 'over there,' and waved his hand to the south and east. That was all. He didn't seem to be alarmed because he was alone, and yet he apparently knew nothing of the country; he was lost in this terrible country where a man could wander for days without finding a house, and yet the boy was whistling as he walked! So Dad took him home and sent out letters all about—to the railroad in particular—to find out if such a boy was missing.

"He received no answer. In the meantime he gave Dan a room in the house; and I remember how Dan sat at the table the first night—I was a very little girl then—and how I laughed at his strange way of eating. His knife was the only thing he was interested in and he made it serve for knife, fork, and spoon, and he held the meat in his fingers while he cut it. The next morning he was missing. One of Dad's range riders picked up Dan several miles to the north, walking along, whistling gayly. The next morning he was missing again and was caught still farther away. After that Dad had a terrible scene with him—I don't know exactly what happened—but Dan promised to run away no more, and ever since then Dad has been closer to Dan than anyone else.

"So Dan grew up. From the time I could first distinctly remember, he was very gentle and good-natured, but he was different, always. After a while he got Black Bart, you know, and then he went out with a halter and captured Satan. Think of capturing a wild mustang with nothing but a halter! He played around with them so much that I was jealous of them. So I kept with them until Bart and Satan were rather used to me. Bart would even play with me now and then when Dan wasn't near. And so finally Dan and I were to be married.

"Dad didn't like the idea. He was afraid of what Dan might become. And he was right. One day, in a saloon that used to stand on that hill over there, Dan had a fight—his first fight—with a man who had struck him across the mouth for no good reason. That man was Jim Silent. Of course you've heard of him?"

"Never."

"He was a famous long-rider—an outlaw with a very black record. At the end of that fight he struck Dan down with a chair and escaped. I went down to Dan when I heard of the fight—Black Bart led me down, to be exact—but Dan would not come back to the house, and he'd have no more to do with anyone until he had found Jim Silent. I can't tell you everything that happened. Finally he caught Jim Silent and killed him—with his bare hands. Buck Daniels saw it. Then Dan came back to us, but on the first night he began to grow restless. It was last Fall—the wild geese were flying south—and while they were honking in the sky Dan got up, said good-bye, and left us. We have never seen him again until to-night. All we knew was that he had ridden south—after the wild geese."

A long silence fell between them, for the doctor was thinking hard.

"And when he came back," he said, "Barry did not know you? I mean you were nothing to him?"

"You were there," said the girl, faintly.

"It is perfectly clear," said Byrne. "If it were a little more commonplace it might be puzzling, but being so extraordinary it clears itself up. Did you really expect the dog, the wolf-dog, Black Bart, to remember you?"

"I may have expected it."

"But you were not surprised, of course!"

"Naturally not."

"Yet you see that Dan Barry—Whistling Dan, you call him—was closer to Black Bart than he was to you?"

"Why should I see that?"

"You watched him a moment ago when he was leaning over the dog."

He watched her draw her dressing gown closer about her, as though the cold bit more keenly then.

She said simply: "Yes, I saw."

"Don't you see that he is simply more in tune with the animal world? And it's really no more reasonable to expect Black Bart to remember you than it is to expect Dan Barry to remember you? It's quite plain. When you go back to the beginning man was simply an animal, without the higher senses, as we call them. He was simply a brute, living in trees or in caves. Afterwards he grew into the thing we all know. But why not imagine a throw-back into the earlier instincts? Why not imagine the creature devoid of the impulses of mind, the thing which we call man, and see the splendid animal? You saw in Dan Barry simply a biological sport—the freak—the thing which retraces the biological progress and comes close to the primitive. But of course you could not realise this. He seemed a man, and you accepted him as a man. In reality he was no more a man than Black Bart is a man. He had the face and form of a man, but his instincts were as old as the ages. The animal world obeys him. Satan neighs in answer to his whistle. The wolf-dog licks his hand at the point of death. There is the profound difference, always. You try to reconcile him with other men; you give him the attributes of other men. Open your eyes; see the truth: that he is no more akin to man than Black Bart is like a man. And when you give him your affection, Miss Cumberland, you are giving your affection to a wild wolf! Do you believe me?"

He knew that she was shaken. He could feel it, even without the testimony of his eyes to witness. He went on, speaking with great rapidity, lest she should escape from the influence which he had already gained over her.

"I felt it when I first saw him—a certain nameless kinship with elemental forces. The wind blew through the open door—it was Dan Barry. The wild geese called from the open sky—for Dan Barry. These are the things which lead him. These the forces which direct him. You have loved him; but is love merely a giving? No, you have seen in him a man, but I see in him merely the animal force."

She said after a moment: "Do you hate him—you plead against him so passionately?"

He answered: "Can you hate a thing which is not human? No, but you can dread it. It escapes from the laws which bind you and which bind me. What standards govern it? How can you hope to win it? Love? What beauty is there in the world to appeal to such a creature except the beauty of the marrow-bone which his teeth have the strength to snap?"

"Ah, listen!" murmured the girl. "Here is your answer!"

And Doctor Randall Byrne heard a sound like the muted music of the violin, thin and small and wonderfully penetrating. He could not tell, at first, what it might be. For it was as unlike the violin as it was like the bow and the rosined strings. Then he made out, surely, that it was the whistling of a human being.

It followed no tune, no reasoned theme. The music was beautiful in its own self. It rose straight up like the sky-lark from the ground, sheer up against the white light of the sky, and there it sang against heaven's gate. He had never heard harmony like it. He would never again hear such music, so thin and yet so full that it went through and through him, until he felt the strains take a new, imitative life within him. He would have whistled the strains himself, but he could not follow them. They escaped him, they soared above him. They followed no law or rhythm. They flew on wings and left him far below. The girl moved away from him as if led by an invisible hand, and now she stood at the extremity of the porch. He followed her.

"Do you hear?" she cried, turning to him.

"What is it?" asked the doctor.

"It is he! Don't you understand?"

"Barry? Yes! But what does the whistling mean; is it for his wolf-dog?"

"I don't know," she answered quickly. "All I understand is that it is beautiful. Where are your theories and explanations now, Doctor Byrne?".

"It is beautiful—God knows!—but doesn't the wolf-dog understand it better than either you or I?"

She turned and faced Byrne, standing very close, and when she spoke there was something in her voice which was like a light. In spite of the dark he could guess at every varying shade of her expression.

"To the rest of us," she murmured, "Dan has nothing but silence, and hardly a glance. Buck saved his life to-night, and yet Dan remembered nothing except the blow which had been struck. And now—now he pours out all the music in his soul for a dumb beast. Listen!"

He saw her straighten herself and stand taller.

"Then through the wolf—I'll conquer through the dumb beast!"

She whipped past Byrne and disappeared into the house; at the same instant the whistling, in the midst of a faint, high climax, broke, shivered, and was ended. There was only the darkness and the silence around Byrne, and the unsteady wind against his face.

CHAPTER XXV
WERE-WOLF

Doctor Byrne, pacing the front veranda with his thoughtful head bowed, saw Buck Daniels step out with his quirt dangling in his hand, his cartridge belt buckled about his waist, and a great red silk bandana knotted at his throat.

He was older by ten years than he had been a few days before, when the doctor first saw him. To be sure, his appearance was not improved by a three days' growth of beard. It gave his naturally dark skin a dirty cast, but even that rough stubble could not completely shroud the new hollows in Daniels' cheeks. His long, black, uncombed hair, sagged down raggedly across his forehead, hanging almost into his eyes; the eyes themselves were sunk in such formidable cavities that Byrne caught hardly more than two points of light in the shadows. All the devil-may-care insouciance of Buck Daniels was quite, quite gone. In its place was a dogged sullenness, a hang-dog air which one would not care to face of a dark night or in a lonely place. His manner was that of a man whose back is against the wall, who, having fled some keen pursuit, has now come to the end of his tether and prepares for desperate even if hopeless battle. There was that about him which made the doctor hesitate to address the cowpuncher.

At length he said: "You're going out for an outing, Mr. Daniels?"

Buck Daniels started violently at the sound of this voice behind him, and whirled upon the doctor with such a set and contorted expression of fierceness that Byrne jumped back.

"Good God, man!" cried the doctor, "What's up with you?"

"Nothin'," answered Buck, gradually relaxing from his first show of suspicion. "I'm beating it. That's all."

"Leaving us?"

"Yes."

"Not really!"

"D'you think I ought to stay?" asked Buck, with something of a sneer.

The doctor hesitated, frowning in a puzzled way. At length he threw out his hands in a gesture of mute abandonment.

"My dear fellow," he said with a faint smile, "I've about stopped trying to think."

At this Buck Daniels grinned mirthlessly.

"Now you're talkin' sense," he nodded. "They ain't no use in thinking."

"But why do you leave so suddenly?"

Buck Daniels shrugged his broad shoulders.

"I am sure," went on Byrne, "that Miss Cumberland will miss you."

"She will not," answered the big cowpuncher. "She's got her hands full with—him."

"Exactly. But if it is more than she can do, if she makes no headway with that singular fellow—she may need help–"

He was interrupted by a slow, long-drawn, deep-throated curse from Buck Daniels.

"Why in hell should I help her with—him?"

"There is really no reason," answered the doctor, alarmed, "except, I suppose, old friendship–"

"Damn old friendship!" burst out Buck Daniels. "There's an end to all things and my friendship is worn out—on both sides. It's done!"

He turned and scowled at the house.

"Help her to win him over? I'd rather stick the muzzle of my gun down my throat and pull the trigger. I'd rather see her marry a man about to hang. Well—to hell with this place. I'm through with it. S'long, doc."

But Doctor Byrne ran after him and halted him at the foot of the steps down from the veranda.

"My dear Mr. Daniels," he urged, touching the arm of Buck. "You really mustn't leave so suddenly as this. There are a thousand questions on the tip of my tongue."

Buck Daniels regarded the professional man with a hint of weariness and disgust.

"Well," he said, "I'll hear the first couple of hundred. Shoot!"

"First: the motive that sends you away."

"Dan Barry."

"Ah—ah—fear of what he may do?"

"Damn the fear. At least, it's him that makes me go."

"It seems an impenetrable mystery," sighed the doctor. "I saw you the other night step into the smoking hell of that barn and keep the way clear for this man. I knew, before that, how you rode and risked your life to bring Dan Barry back here. Surely those are proofs of friendship!"

Buck Daniels laughed unpleasantly. He laid a large hand on the shoulder of the doctor and answered: "If them was the only proofs, doc, I wouldn't feel the way I do. Proofs of friendship? Dan Barry has saved me from the—rope!—and he's saved me from dyin' by the gun of Jim Silent. He took me out of a rotten life and made me a man that could look honest men in the face!"

He paused, swallowing hard, and the doctor's misty, overworked eyes lighted with some comprehension. He had felt from the first a certain danger in this big fellow, a certain reckless disregard of laws and rules which commonly limit the actions of ordinary men. Now part of the truth was hinted at. Buck Daniels, on a time, had been outside the law; and Barry had drawn him back to the ways of men. That explained some of the singular bond that lay between them.

"That ain't all," went on Buck. "Blood is thick, and I've loved him better nor a brother. I've gone to hell and back for him. For him I took Kate Cumberland out of the hands of Jim Silent, and I left myself in her place. I took her away and all so's she could go to him. Damn him! And now on account of him I got to leave this place."

His voice rose to a ringing pitch.

"D'you think it's easy for me to go? D'you think it ain't like tearing a finger-nail off'n the flesh for me to go away from Kate? God knows what she means to me! God knows, but if He does, He's forgotten me!"

Anguish of spirit set Buck Daniels shaking, and the doctor looked on in amazement. He was like one who reaches in his pocket for a copper coin and brings out a handful of gold-pieces.

"Kind feelin's don't come easy to me," went on Buck Daniels. "I been raised to fight. I been raised to hard ridin' and dust in the throat. I been raised on whiskey and hate. And then I met Dan Barry, and his voice was softer'n a girl's voice, and his eyes didn't hold no doubt of me. Me that had sneaked in on him at night and was goin' to kill him in his sleep—because my chief had told me to! That was the Dan Barry what I first knew. He give me his hand and give me the trust of his eyes, and after he left me I sat down and took my head between my hands and my heart was like to bust inside me. It was like the clouds had blowed away from the sun and let it shine on me for the first time in my life. And I swore that if the time come I'd repay him. For every cent he give me I'd pay him back in gold. I'd foller to the end of the world to do what he bid me do."

His voice dropped suddenly, choked with emotion.

"Oh, doc, they was tears come in my eyes; and I felt sort of clean inside, and I wasn't ashamed of them tears! That was what Dan Barry done for me!

"And I did pay him back, as much as I could. I met Kate Cumberland and she was to me among girls what Dan Barry was to me among men. I ain't ashamed of sayin' it. I loved her till they was a dryness like ashes inside me, but I wouldn't even lift up my eyes to her, because she belonged to him. I follered her around like a dog. I done her bidding. I asked no questions. What she wanted—that was law to me, and all the law I wanted. All that I done for the sake of Dan Barry. And then I took my life in my hands for him—not once, but day after day.

"Then he rode off and left her and I stayed behind. D'you think it's been easy to stay here? Man, man, I've had to hear her talkin' about Dan Barry day after day, and never a word for me. And I had to tell her stories about Dan and what he'd used to do, and she' sit with her eyes miles away from me, listenin' an smilin' and me there hungerin' for just one look out of her eyes—hungerin' like a dyin' dog for water. And then for her and Joe I rode down south and when I met Dan Barry d'you think they was any light in his eyes when he seen me?

"No, he'd forgotten me the way even a hoss won't forget his master. Forgot me after a few months—and after all that'd gone between us! Not even Kate—even she was nothin' to him. But still I kept at it and I brought him back. I had to hurt him to do it, but God knows it wasn't out of spite that I hit him—God knows!

"And when I seen Dan go into that burnin' barn I says to myself: 'Buck, if nothin' is done that wall will fall and there's the end of Dan Barry. There's the end of him, that ain't any human use, and when he's finished after a while maybe Kate will get to know that they's other men in the world besides Dan.' I says that to myself, deep and still inside me. And then I looked at Kate standin' in that white thing with her yaller hair all blowin' about her face—and I wanted her like a dyin' man wants heaven! But then I says to myself again: 'No matter what's happened, he's been my friend. He's been my pal. He's been my bunkie.'

"Doc, you ain't got a way of knowin' what a partner is out here. Maybe you sit in the desert about a thousand miles from nowhere, and across the little mesquite fire, there's your pal, the only human thing in sight. Maybe you go months seein' only him. If you're sick he takes care of you. If you're blue he cheers you up. And that's what Dan Barry was to me. So I stands sayin' these things to myself, and I says: 'If I keep that wall from fallin' Dan'll know about it, and they won't be no more of that yaller light in his eyes when he looks at me. That's what I says to myself, poor fool!

"And I went into the fire and I fought to keep that wall from fallin'. You know what happened. When I come out, staggerin' and blind and three parts dead, Dan Barry looks up to me and touches his face where I'd hit him, and the yaller comes up glimmerin' and blazin' in his eyes. Then I went back to my room and I fought it out.

"And here's where I stand now. If I stay here, if I see that yaller light once more, they won't be no waitin'. Him and me'll have to have it out right then. Am I a dog, maybe, that I got to stand around and jump when he calls me?"

"My dear fellow—my dear Mr. Daniels!" cried the horrified Doctor Byrne. "Surely you're wrong. He wouldn't go so far as to make a personal attack upon you!"

"Wouldn't he? Bah! Not if he was a man, no. I tell you, he ain't a man; he's what the canuks up north call a were-wolf! There ain't no mercy or kindness in him. The blood of a man means nothin' to him. The world would be better rid of him. Oh, he can be soft and gentle as a girl. Mostly he is. But cross him once and he forgets all you done for him. Give him a taste of blood and he jumps at your throat. I tell you, I've seen him do it!"

He broke off with a shudder.

"Doc," he said, in a lower and solemn voice. "Maybe I've said too much. Don't tell Kate nothin' about why I'm goin'. Let her go on dreamin' her fool dream. But now hear what I'm sayin'; If Dan Barry crosses me once more, one of us two dies, and dies damned quick. It may be me, it may be him, but I've come to the end of my rope. I'm leavin' this place till Barry gets a chance to come to his senses and see what I've done for him. That's all. I'm leavin' this place because they's a blight on it, and that blight is Dan Barry. I'm leaving this place because—doc—because I can smell the comin' of bloodshed in it. They's a death hangin' over it. If the lightnin' was to hit and burn it up, house and man, the range would be better for it!"

And he turned on his heel and strode slowly down towards the corral. Doctor Byrne followed his progress with starting eyes.
