"The flames of the sacrifice!" gasped Celia, quickening her pace. "Hasten!"
Somewhere in his big, weary body Harrison found enough reserve energy to keep up with her. She seemed to run lightly over bogs that engulfed him to the knees. She possessed the swamp dweller's instinct for safe footing. Ahead of them Harrison saw the shine of something that was not mud, and Celia halted at the verge of a stretch of noisome water.
"The Place of the Altar is surrounded by water on all sides but one," she hissed. "We are in the very heart of the swamp, deeper than anyone ever goes except on such occasions as these. There are no cabins near. Follow me! I have a bridge none knows of except myself."
At a point where the sluggish stream narrowed to some fifty feet, a fallen tree spanned it. Celia ran out upon it, balancing herself upright. She swayed across, a slim ghostly figure in the cloudy light. Harrison straddled the log and hitched himself ignominiously along.
He was too weary to trust his equilibrium. His feet dangled a foot or so above the black surface, and Celia, waiting impatiently on the further bank as she peered anxiously at the distant glow, cast him a look over her shoulder and cried a sudden urgent warning.
Harrison jerked up his legs just as something bulky and grisly heaved up out of the water with a great splash and an appalling clash of mighty fangs. Harrison fairly flung himself over the last few feet and landed on the further bank in a more demoralized condition than he would have admitted. A criminal in a dark room with a knife was less nerve-shaking than these ghoulish slayers of the dark waters.
The ground was firmer; they were, as Celia said, on a sort of island in the heart of the marshes. The girl threaded her supple way among the cypresses, panting with the intensity of her emotions. Perspiration soaked her; the hand that held Harrison's wrist was wet and slippery.
A few minutes later, when the glow in the trees had grown to an illuminating glare, she halted and slipped to the damp mold, drawing her companion with her. They looked out upon a scene incredible in its primitive starkness.
There was a clearing, free of underbrush, circled by a black wall of cypress. From its outer edge a sort of natural causeway wandered away into the gloom, and over that low ridge ran a trail, beaten by many feet. The trail ended in the clearing, the ultimate end of the path that Harrison had followed into the swamp. On the other side of the clearing there was a glimpse of dusky water, reflecting the firelight.
In a wide horseshoe formation, their backs to the causeway, sat some fifty men, women and children, resembling Celia Pompoloi in complexion. Harrison had not supposed that so many people inhabited the swamp. Their gaze was fixed on an object in the center of the opening of the human horseshoe. This was a great block of dark wood that had an unfamiliar appearance, as of an altar, brought from afar. There was an intolerable suggestion about that block, and the misshapen, leering figure that rose behind it—a fantastically carven idol, to whose bestial features the flickering firelight lent life and mobility. Harrison intuitively knew that this monstrosity was never carved in America. The yellow people had brought it with them from Haiti, and surely their black ancestors had brought it originally from Africa. There was an aura of the Congo about it, the reek of black squalling jungles, and squirming faceless shapes of a night more primeval than this. Harrison was not superstitious, but he felt gooseflesh rise on his limbs. At the back of his consciousness dim racial memories stirred, conjuring up unstable and monstrous images from the dim mists of the primitive, when men worshipped such gods as these.
Before the idol, near the block, sat an old crone, striking a bowl tom- tom with quick staccato strokes of her open hands; it growled and rumbled and muttered, and the squatting Negroes swayed and chanted softly in unison. Their voices were low, but they hummed with a note of hysteria. The fire struck gleams from their rolling eyeballs and shining teeth.
Harrison looked in vain for John Bartholomew and Woon Shang. He reached out a hand to get his companion's attention. She did not heed him. Her supple figure was tense and quivering as a taut wire under his hand. A sudden change in the chanting, a wild wolfish baying, brought him about again.
Out of the shadows of the trees behind the idol strode John Bartholomew. He was clad only in a loin cloth, and it was as if he had doffed his civilized culture with his clothing. His facial expression, his whole bearing, were changed; he was like an image of barbarism incarnate. Harrison stared at the knotted biceps, the ridged body muscles which the firelight displayed. But something else gripped his whole attention. With John Bartholomew came another, unwillingly, at the sight of whom the crowd gave tongue to another bestial yell.
About Bartholomew's mighty left hand was twisted the pigtail of Woon Shang, whom he dragged after him like a fowl to the chopping block. The Chinaman was stark naked, his yellow body gleaming like old ivory in the fire. His hands were bound behind his back, and he was like a child in the grasp of his executioner. Woon Shang was not a large man; beside the great mulatto he seemed slimmer than ever. His hysterical panting came plainly to Harrison in the silence that fell tensely as the shouting ceased and the Negroes watched with eyes that gleamed redly. His straining feet tore at the sod as he struggled against the inexorable advance of his captor. In Bartholomew's right hand shone a great razor-edged crescent of steel. The watchers sucked in their breath loudly; in a single stride they had returned to the jungle whence they had crawled; they were mad for the bloody saturnalia their ancestors had known.
In Bartholomew's face Harrison read stark horror and mad determination. He sensed that the mulatto was not enjoying this ghastly primordial drama into which be had been trapped. He also realized that the man must go through with it, and that he would go through with it. It was more than the jewel heart of the serpent-god for which Bartholomew strove now; it was the continued dominance of these wolfish devil-worshippers on which his life depended.
Harrison rose to one knee, drew and cocked his revolver and sighted along the blue barrel. The distance was not great, but the light was illusive. But he felt he must trust to the chance of sending a slug crashing through John Bartholomew's broad breast. If he stepped out into the open and tried to arrest the man, the Negroes, in their present fanatical frenzy, would tear him to pieces. If their priest was shot down, panic might seize them. His finger was crooking about the trigger when something was thrown into the fire. Abruptly the flames died down, throwing everything into deep shallow. As suddenly they flared up again, burning with a weird green radiance. The dusky faces looked like those of drowned corpses in the glow.
In the moment of darkness Bartholomew had reached the block. His victim's head was thrust down upon it, and the mulatto stood like a bronze image, his muscular right arm lifted, poising above his head the broad steel crescent. And then, before could strike the blow that would send Woon Shang's head rolling to the misshapen feet of the grinning idol, before Harrison could jerk the trigger, something froze them all in their places.
Into the weird glow moved a figure, so lithely that it seemed to float in the uncertain light rather than move on earthly feet. A groan burst from the Negroes, and they came to their feet like automatons. In the green glow that lent her features the aspect of death, with perspiration dripping from her draggled garment, Celia Pompoloi looked hideously like the corpse of a drowned woman newly risen from a watery grave.
"Celia!"
It was a scream from a score of gaping months. Bedlam followed.
"Celia Pompoloi! Oh Gawd, she done come back from de watah! Done come back from Hell!"
