Lawler—the knowledge that Lawler's father had been a gunman of wide reputation, and that he had taught his son the precision and swiftness that had made him famous in the deadly art.

That knowledge had always exerted a deterring influence upon Singleton; there had been times when he would have drawn a gun on Lawler had it not been that he feared the son might be as swift as the father.

So Singleton had assured himself; he was not afraid of Lawler, he was afraid of the reputation of Lawler's father. Singleton was reluctant to admit that it was not Lawler's gun that he was afraid of, but something that was in the man himself—in his confident manner, in the level glance of his eyes; in the way he looked at Singleton—seeming to hint that he knew the man's thoughts, and that when the time came—if it ever came—he would convince Singleton that his fears were well founded.

And, singularly, Singleton knew it; he knew that if he drew his gun on Lawler, Lawler would anticipate the movement; Singleton had become convinced of it—the conviction had become an obsession. That was why his rage had cooled so suddenly when he had entered the schoolroom.

But he knew, too, that Lawler never sought trouble; that within the past few years—or since Singleton had known him—he had never drawn the gun that reposed at his hip. And that knowledge brought the rage surging back into Singleton's veins. He knew he could talk to Lawler; that he could say some of the things that were in his mind—that had been in his mind all along; and that he would be safe so long as he kept his hands away from his guns.

As he snarled his questions at Lawler he took a step toward him. His eyes were truculent again, his lips in the pout that had been on them when he had entered. If Lawler didn't go for his gun he need have no fear of him. For he was bigger than Lawler, stronger. And if he could goad Lawler into using his fists instead of the dreaded gun he had no doubt of the outcome.

"Singleton," replied Lawler, answering the questions that had been hurled at him; "what I am here for is my business. I don't feel a heap like explaining it."

"Business—bah!" sneered Singleton. "I reckon the business that brought you here could be carried on better with no kids around."

Singleton saw a pin point of fire glow in Lawler's eyes. But he noted with venomous satisfaction that Lawler's hand did not move upward the slightest fraction of an inch toward his gun, and he laughed discordantly, taking another step toward Lawler, so that he would be close enough to strike when the time came.

"Lawler," he said, sticking his face close to the other's, his eyes glittering with the malignant triumph that had seized him over the conviction that Lawler would not try to draw his gun; "I'm figgerin' on wallopin' you like you walloped my kid. Understand? I'm aimin' to make you fight—with your fists. I'm goin' to knock hell out of you!".

Lawler had not moved. Had Singleton not been so obsessed with thoughts of an easy victory he might have noted that the pin point of fire that had glowed in Lawler's eyes had grown larger, and that his muscles had stiffened. Also, had Singleton been observant at this minute he must have seen a faint grin on Lawler's lips.

"Hell's fire!" snarled Singleton; "won't anything make you fight! There's that girl there—Ruth Hamlin. You think she's got a right to be proud as she is. Lawler, you don't know her; you don't know what's goin' on over there at the Two Bar—Hamlin's ranch. This here school teachin' of hers is only a blind—a blind, I tell you! A blind for other things that her an'—"

Ruth's sharp, protesting cry was drowned in a sodden swish as Lawler struck. His fist had shot upward with the weight of his body behind it, landing fairly on the point of Singleton's chin, snapping his teeth shut with a clack.

Singleton's head went back, his body rose from the floor. He came down with his knees unjointed, his head sagging on his chest; came down in a heap and tumbled forward upon his face, his arms limp, the fingers slowly spreading.

For an instant Lawler stood over him, pale, his eyes agleam. Then when Singleton did not move he turned to Ruth, smiling faintly.

"Go home, now, Ruth, before this beast comes to life. Go out and send the children away. I've got something to say to Singleton."

Ruth looked intently at him, saw there would be no use of pleading with him, and walked to the door, dragging the children away from it, telling them to go home.

Jimmy Singleton, terrorized by the thing that had happened to his father, needed no urging. He ran, whimpering, toward town, the other children following.

Ruth went to the shed where she kept her pony, threw saddle and bridle on him and led him to the step, where she usually mounted.

The door of the schoolhouse was closed. Trailing the reins over the pony's head, she ran to one of the windows—a small one in the center of the side wall, dust-begrimed, with one pane of glass missing.

Peering within, she saw Singleton sitting up, staring dazedly around, supporting himself with his hands, an expression of almost laughable, bewilderment on his face.

Lawler was standing near him—big, stern, seeming to wait for Singleton to rise before he spoke to him.

And while Ruth watched, Singleton staggered to his feet. He swayed uncertainly as he faced Lawler; and when Lawler advanced toward him he cringed and staggered back, raising one arm as though to ward off an expected blow.

Ruth heard his voice; it was a whine, tremulous with fear.

"Don't hit me again, Lawler; I wasn't meanin' anything!"

And then Ruth saw that Singleton must have been struck a second time, for high up on his left cheek was a huge gash that had suffused his chin and neck with blood. She remembered that while saddling and bridling her pony she had heard a sound from within the schoolhouse, but she had thought then that it must have been Lawler moving a chair. Plainly, Singleton had recovered from the first blow, and had received another.

Lawler's voice again reached her. It was low, vibrant with passion.

"Singleton, I ought to kill you. I will kill you if you ever tell that girl that you know her father is a rustler. Damn your hide, she knows it now—and it's breaking her heart!

"I'm warning you. Don't you ever go near the Two Bar again. Don't you ever buy another steer from Hamlin. Don't even speak to him. I'll kill you sure as hell if you do!"

Ruth reeled away from the window. She got on her pony somehow, taking care to make no sound, for she did not want Lawler to know that she had heard. Once on the pony she sent the little animal rapidly away, toward the Two Bar—away from Lawler and from that happiness for which she had hoped despite the hideous knowledge which for months had tortured her.

Inside the schoolhouse Singleton was standing, beaten by the man over whom he had thought to triumph easily; by a man whose pallid face and blazing eyes conveyed to Singleton something of the terrible power and energy of him when aroused.

Singleton did not think of his guns, now; he was aware of nothing but the great awe that had seized him. And as Lawler watched, saying nothing more, Singleton turned from him and slunk out through the door.
