Holding the book in one hand and the knife ready in the other, he began to repeat the jumble of unintelligible sounds.

As he read, the syllables appeared to exert some unearthly influence upon him, so that his voice rose to a savage howl, a high-pitched inhuman ululation which penetrated to the farthest depths of the swamp. At intervals his voice sank to low gutturals or a thin sibilant hiss.

And then, at the last enunciation of the oft-repeated word, "Nyogtha", there reached his ears as from a vast distance a sound like the rushing of a mighty wind, although not even a leaf stirred on the surrounding trees.

The book suddenly darkened in his hand and he saw that a shadow had fallen across the page.

He glanced up—and madness reeled in his brain.

Squatting on the edge of the slab was a shape which lived in nightmare, a squamous taloned thing like a monstrous gargoyle or a malformed toad which stared at him out of questing red eyes.

He froze in horror and a sudden rage flamed in the thing's eyes. It thrust out its neck and an angry hiss issued from its mottled beak.

Emmet Telquist was galvanized into action. He knew what the thing wanted—life blood.

Raising the knife, he advanced and was about to plunge it downward into the sheep when a new horror seized him.

The ewe was already dead. The unspeakable presence which squatted beside it had already claimed it. It had died of fright. Its eyes were glazed and there was no indication that it still breathed.
