Out of the unimaginable blackness beyond the gangrenous glare of that cold flame, out of the tartarean leagues through which that oily river rolled uncanny, unheard, and unsuspected, there flopped rhythmically a horde of tame, trained, hybrid winged things that no sound eye could ever wholly grasp, or sound brain ever wholly remember. They were not altogether crows, nor moles, nor buzzards, nor ants, nor vampire bats, nor decomposed human beings, but something I cannot and must not recall. They flopped limply along, half with their webbed feet and half with their membranous wings; and as they reached the throng of celebrants the cowled figures seized and mounted them, and rode off one by one along the reaches of that unlighted river, into pits and galleries of panic where poison springs feed frightful and undiscoverable cataracts. The old spinning woman had gone with the throng, and the old man remained only because I had refused when he motioned me to seize an animal and ride like the rest. I saw when I staggered to my feet that the amorphous flute-player had rolled out of sight, but that two of the beasts were patiently standing by. As I hung back, the old man produced his stylus and tablet and wrote that he was the true deputy of my fathers who had founded the Yule worship in this ancient place; that it had been decreed I should come back; and that the most secret mysteries were yet to be performed. He wrote this in a very ancient hand, and when I still hesitated he pulled from his loose robe a seal ring and a watch, both with my family arms, to prove that he was what he said. But it was a hideous proof, because I knew from old papers that that watch had been buried with my great-great-great-great-grandfather in 1698. Presently the old man drew back his hood and pointed to the family resemblance in his face, but I only shuddered, because I was sure that the face was merely a devilish waxen mask. The flopping animals were now scratching restlessly at the lichens, and I saw that the old man was nearly as restless himself. When one of the things began to waddle and edge away, he turned quickly to stop it; so that the suddenness of his motion dislodged the waxen mask from what should have been his head. And then, because that nightmare’s position barred me from the stone staircase down which we had come, I flung myself into the oily underground river that bubbled somewhere to the caves of the sea; flung myself into that putrescent juice of earth’s inner horrors before the madness of my screams could bring down upon me all the charnel legions these pest-gulfs might conceal. * * * * *
