Cal Reynolds shifted his tobacco quid to the other side of his mouth as he squinted down the dull blue barrel of his Winchester. His jaws worked methodically, their movement ceasing as he found his bead. He froze into rigid immobility; then his finger hooked on the trigger. The crack of the shot sent the echoes rattling among the hills, and like a louder echo came an answering shot. Reynolds flinched down, flattening his rangy body against the earth, swearing softly. A gray flake jumped from one of the rocks near his head, the ricocheting bullet whining off into space. Reynolds involuntarily shivered. The sound was as deadly as the singing of an unseen rattler.

He raised himself gingerly high enough to peer out between the rocks in front of him. Separated from his refuge by a broad level grown with mesquite-grass and prickly-pear, rose a tangle of boulders similar to that behind which he crouched. From among these boulders floated a thin wisp of whitish smoke. Reynold’s keen eyes, trained to sun-scorched distances, detected a small circle of dully gleaming blue steel among the rocks. That ring was the muzzle of a rifle, but Reynolds well knew who lay behind that muzzle.

The feud between Cal Reynolds and Esau Brill had been long, for a Texas feud. Up in the Kentucky mountains family wars may straggle on for generations, but the geographical conditions and human temperament of the Southwest were not conducive to long-drawn-out hostilities. There feuds were generally concluded with appalling suddenness and finality. The stage was a saloon, the streets of a little cow-town, or the open range. Sniping from the laurel was exchanged for the close-range thundering of six-shooters and sawed-off shotguns which decided matters quickly, one way or the other.

The case of Cal Reynolds and Esau Brill was somewhat out of the ordinary. In the first place, the feud concerned only themselves. Neither friends nor relatives were drawn into it. No one, including the participants, knew just how it started. Cal Reynolds merely knew that he had hated Esau Brill most of his life, and that Brill reciprocated. Once as youths they had clashed with the violence and intensity of rival young catamounts. From that encounter Reynolds carried away a knife scar across the edge of his ribs, and Brill a permanently impaired eye. It had decided nothing. They had fought to a bloody gasping deadlock, and neither had felt any desire to ‘shake hands and make up.’ That is a hypocrisy developed in civilization, where men have no stomach for fighting to the death. After a man has felt his adversary’s knife grate against his bones, his adversary’s thumb gouging at his eyes, his adversary’s boot-heels stamped into his mouth, he is scarcely inclined to forgive and forget, regardless of the original merits of the argument.

So Reynolds and Brill carried their mutual hatred into manhood, and as cowpunchers riding for rival ranches, it followed that they found opportunities to carry on their private war. Reynolds rustled cattle from Brill’s boss, and Brill returned the compliment. Each raged at the other’s tactics, and considered himself justified in eliminating his enemy in any way that he could. Brill caught Reynolds without his gun one night in a saloon at Cow Wells, and only an ignominious flight out the back way, with bullets barking at his heels, saved the Reynolds scalp.

Again Reynolds, lying in the chaparral, neatly knocked his enemy out of his saddle at five hundred yards with a .30- .30 slug, and, but for the inopportune appearance of a line-rider, the feud would have ended there, Reynolds deciding, in the face of this witness, to forego his original intention of leaving his covert and hammering out the wounded man’s brains with his rifle butt.

Brill recovered from his wound, having the vitality of a longhorn bull, in common with all his sun-leathered iron-thewed breed, and as soon as he was on his feet, he came gunning for the man who had waylaid him.

Now after these onsets and skirmishes, the enemies faced each other at good rifle range, among the lonely hills where interruption was unlikely.

For more than an hour they had lain among the rocks, shooting at each hint of movement. Neither had scored a hit, though the .30- .30’s whistled perilously close.

In each of Reynold’s temples a tiny pulse hammered maddeningly. The sun beat down on him and his shirt was soaked with sweat. Gnats swarmed about his head, getting into his eyes, and he cursed venomously. His wet hair was plastered to his scalp; his eyes burned with the glare of the sun, and the rifle barrel was hot to his calloused hand. His right leg was growing numb and he shifted it cautiously, cursing at the jingle of the spur, though he knew Brill could not hear. All this discomfort added fuel to the fire of his wrath. Without process of conscious reasoning, he attributed all his suffering to his enemy. The sun beat dazingly on his sombrero, and his thoughts were slightly addled. It was hotter than the hearthstone of hell among those bare rocks. His dry tongue caressed his baked lips.

Through the muddle of his brain burned his hatred of Esau Brill. It had become more than an emotion: it was an obsession, a monstrous incubus. When he flinched from the whip-crack of Brill’s rifle, it was not from fear of death, but because the thought of dying at the hands of his foe was an intolerable horror that made his brain rock with red frenzy. He would have thrown his life away recklessly, if by so doing he could have sent Brill into eternity just three seconds ahead of himself.

He did not analyze these feelings. Men who live by their hands have little time for self-analysis. He was no more aware of the quality of his hate for Esau Brill than he was consciously aware of his hands and feet. It was part of him, and more than part: it enveloped him, engulfed him; his mind and body were no more than its material manifestations. He was the hate; it was the whole soul and spirit of him. Unhampered by the stagnant and enervating shackles of sophistication and intellectuality, his instincts rose sheer from the naked primitive. And from them crystallized an almost tangible abstraction--a hate too strong for even death to destroy; a hate powerful enough to embody itself in itself, without the aid or the necessity of material substance.
