run no more. He had given up all attempt at reason and rationality; he no longer cared why the beauty of the Tree was so dreadful. He only knew that until all space lay between him and its symmetry he must run and run and run.
What brought that frenzied madness to an end he never knew. When sanity returned to him he was lying face down on the flower-spangled sward in a silence so deep that his ears ached with its heaviness. The grass was cool against his cheek. For a moment he fought the back-flow of knowledge into his emptied mind. When it came, the memory of that horror he had fled from, he started up with a wild thing’s swiftness and glared around pale-eyed into the unchanging dusk. He was alone. Not even a rustle in the leaves spoke of the tree-folk’s presence.
For a moment he stood there alert, wondering what had roused him, wondering what would come next. He was not left long in doubt. The answer was shrilling very, very faintly through that aching quiet, an infinitesimally tiny, unthinkably far-away murmur which yet pierced his ear-drums with the sharpness of tiny needles. Breathless, he strained in listening. Swiftly the sound grew louder. It deepened upon the silence, sharpened and shrilled until the thin blade of it was vibrating in the center of his innermost brain.
And still it grew, swelling louder and louder through the twilight world in cadences that were rounding into a queer sort of music and taking on such an unbearable sweetness that Smith pressed his hands over his ears in a futile attempt to shut the sound away. He could not. It rang in steadily deepening intensities through every fiber of his being, piercing him with thousands of tiny music-blades that quivered in his very soul with intolerable beauty. And he thought he sensed in the piercing strength of it a vibration of queer, unnamable power far mightier than anything ever generated by man, the dim echo of some cosmic dynamo’s hum.
The sound grew sweeter as it strengthened, with a queer, inexplicable sweetness unlike any music he had ever heard before, rounder and fuller and more complete than any melody made up of separate notes. Stronger and stronger he felt the certainty that it was the song of some mighty power, humming and throbbing and deepening through the twilight until the whole dim land was one trembling reservoir of sound that filled his entire consciousness with its throbbing, driving out all other thoughts and realizations, until he was no more than a shell that vibrated in answer to the calling.
For it was a calling. No one could listen to that intolerable sweetness without knowing the necessity to seek its source. Remotely in the back of his mind Smith remembered the tree-folk’s warning, “When Thag calls, you must answer.” Not consciously did he recall it, for all his consciousness was answering the siren humming in the air, and, scarcely realizing that he moved, he had turned toward the source of that calling, stumbling blindly over the flowery sward with no thought in his music-brimmed mind but the need to answer that lovely, power-vibrant summoning.
Past him as he went on moved other shapes, little and dark-skinned and ecstatic, gripped like himself in the hypnotic melody. The tree-folk had forgotten even their inbred fear at Thag’s calling, and walked boldly through the open twilight, lost in the wonder of the song.
Smith went on with the rest, deaf and blind to the land around him, alive to one thing only, that summons from the siren tune. Unrealizingly, he retraced the course of his frenzied flight, past the trees and bushes he had blundered through, down the slope that led to the Tree’s hollow, through the thinning of the underbrush to the very edge of the last line of foliage which marked the valley’s rim.

By now the calling was so unbearably intense, so intolerably sweet that somehow in its very strength it set free a part of his dazed mind as it passed the limits of audible things and soared into ecstasies which no senses bound. And though it gripped him ever closer in its magic, a sane part of his brain was waking into realization. For the first time alarm came back into his mind, and by slow degrees the world returned about him. He stared stupidly at the grass moving by under his pacing feet. He lifted a dragging head and saw that the trees no longer rose about him, that a twilit clearing stretched away on all sides toward the forest rim which circled it, that the music was singing from some source so near that—that—
The Tree! Terror leaped within him like a wild thing. The Tree, quivering with unbearable clarity in the thick, dim air, writhed above him, blossoms blazing with bloody radiance and every branch vibrant and undulant to the tune of that unholy song. Then he was aware of the lovely, luminous whiteness of the priestess swaying forward under the swaying limbs, her hair rippling back from the loveliness of her as she moved.
Choked and frenzied with unreasoning terror, he mustered every; effort that was In him to turn, to run again like a madman out of that dreadful hollow, to hide himself under the weight of all space from the menace of the Tree. And all the while he fought, all the while panic drummed like mad in his brain, his relentless body plodded on straight toward the hideous loveliness of that siren singer towering above him. From the first he had felt subconsciously that it was Thag who called, and now, in the very center of that ocean of vibrant power, he knew. Gripped in the music’s magic, he went on.
All over the clearing other hypnotized victims were advancing slowly, with mechanical steps and wide, frantic eyes as the tree-folk came helplessly to their god’s calling. He watched a group of little, dusky sacrifices pace step by step nearer to the Tree’s vibrant branches. The priestess came forward to meet them with outstretched arms. He saw her take the foremost gently by the hands. Unbelieving, hypnotized with horrified incredulity, he watched her lead the rigid little creature forward under the fabulous Tree whose limbs yearned downward like hungry snakes, the great flowers glowing with avid color.
He saw the branches twist out and lengthen toward the sacrifice, quivering with eagerness. Then with a tiger’s leap they darted, and the victim was swept out of the priestess’ guiding hands up into the branches that darted round like tangled snakes in a clot that hid him for an instant from view. Smith heard a high, shuddering wail ripple out from that knot of struggling branches, a dreadful cry that held such an infinity of purest horror and understanding that he could not but believe that Thag’s victims in the moment of their doom must learn the secret of his horror. After that one frightful cry came silence. In an instant the limbs fell apart again from emptiness. The little savage had melted like smoke among their writhing, too quickly to have been devoured, more as if he had been snatched into another dimension in the instant the hungry limbs hid him. Flame-tipped, avid, they were dipping now toward another victim as the priestess paced serenely forward.
And still Smith’s rebellious feet were carrying him on, nearer and nearer the writhing peril that towered over his head. The music shrilled like pain. Now he was so close that he could see the hungry flower-mouths in terrible detail as they faced round toward him. The limbs quivered and poised like cobras, reached out with a snakish lengthening, down inexorably toward his shuddering helplessness. The priestess was turning her calm white face toward his.
Those arcs and changing curves of the branches as they neared were sketching lines of pure horror whose meaning he still could not understand, save that they deepened in dreadfulness as he neared. For the last time that urgent wonder burned up in his mind why—why so simple a thing as this fabulous Tree should be infused with an indwelling terror strong enough to send his innermost soul frantic with revulsion. For the last time—because in that trembling instant as he waited for their touch, as the music brimmed up with unbearable, brain-wrenching intensity, in that one last moment before the flower-mouths seized him—he saw. He understood.
With eyes opened at last by the instant’s ultimate horror, he saw the real Thag. Dimly he knew that until now the thing had been so frightful that his eyes had refused to register its existence, his brain to acknowledge the possibility of such dreadfulness. It had literally been too terrible to see, though his instinct knew the presence of infinite horror. But now, In the grip of that mad, hypnotic song, in the instant before unbearable terror enfolded him, his eyes opened to full sight, and he saw.
