Free Valley of the Worm by Robert E. Howard

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.
    For perhaps a quarter of an hour neither rifle had spoken. Instinct with death as rattlesnakes coiled among the rocks soaking up poison from the sun’s rays, the feudists lay each waiting his chance, playing the game of endurance until the taut nerves of one or the other should snap.
    It was Esau Brill who broke. Not that his collapse took the form of any wild madness or nervous explosion. The wary instincts of the wild were too strong in him for that. But suddenly, with a screamed curse, he hitched up on his elbow and fired blindly at the tangle of stones which concealed his enemy. Only the upper part of his arm and the corner of his blue-shirted shoulder were for an instant visible. That was enough. In that flash-second Cal Reynolds jerked the trigger, and a frightful yell told him his bullet had found its mark. And at the animal pain in that yell, reason and life-long instincts were swept away by an insane flood of terrible joy. He did not whoop exultantly and spring to his feet; but his teeth bared in a wolfish grin and he involuntarily raised his head. Waking instinct jerked him down again. It was chance that undid him. Even as he ducked back, Brill’s answering shot cracked.
    Cal Reynolds did not hear it, because, simultaneously with the sound, something exploded in his skull, plunging him into utter blackness, shot briefly with red sparks.
    The blackness was only momentary. Cal Reynolds glared wildly around, realizing with a frenzied shock that he was lying in the open. The impact of the shot had sent him rolling from among the rocks, and in that quick instant he realized that it had not been a direct hit. Chance had sent the bullet glancing from a stone, apparently to flick his scalp in passing. That was not so important. What was important was that he was lying out in full view, where Esau Brill could fill him full of lead. A wild glance showed his rifle lying close by. It had fallen across a stone and lay with the stock against the ground, the barrel slanting upward. Another glance showed his enemy standing upright among the stones that had concealed him.
    In that one glance Cal Reynolds took in the details of the tall, rangy
