puzzling features. For one thing, the walls were covered with still undeciphered hieroglyphs roughly incised in the brickwork. Another peculiarity was a huge circular aperture in the rear of the vault, blocked by a cave-in evidently caused by the collapse of the house.
But strangest of all was the apparently recent deposit of some fetid, slimy, pitch-black substance on the flagstoned floor, extending in a yard-broad, irregular line with one end at the blocked circular aperture. Those who first opened the vault declared that the place smelled like the snake-house at a zoo.
The diary, which was apparently designed solely to cover an investigation of the dreaded van der Heyl house by the vanished Mr. Typer, has been proved by handwriting experts to be genuine. The script shows signs of increasing nervous strain as it progresses toward the end, in places becoming almost illegible. Chorazin villagers—whose stupidity and taciturnity baffle all students of the region and its secrets—admit no recollection of Mr. Typer as distinguished from other rash visitors to the dreaded house.
The text of the diary is here given verbatim and without comment. How to interpret it, and what, other than the writer's madness, to infer from it, the reader must decide for himself. Only the future can tell what its value may be in solving a generation-old mystery. It may be remarked that genealogists confirm Mr. Typer's belated memory in the matter of Adriaen Sleght.
The Diary
April 17, 1908
Arrived here about 6 p.m. Had to walk all the way from Attica in the teeth of an oncoming storm, for no one would rent me a horse or rig, and I can't run an automobile. This place is even worse than I had expected, and I dread what is coming, even though I long at the same time to learn the secret All too soon will come the night—the old Walpurgis sabbat horror—and after that time in Wales I know what to look for. Whatever comes, I shall not flinch. Prodded by some unfathomable urge, I have given my whole life to the quest of unholy mysteries. I came here for nothing else, and will not quarrel with fate.
It was very dark when I got here, though the sun had by no means set. The storm-clouds were the densest I had ever seen, and I could not have found my way but for the lightning-flashes. The village is a hateful little backwater, and its few inhabitants no better than idiots. One of them saluted me in a queer way, as if he knew me. I could see very little of the landscape—just a small, swampy valley of strange brown weed-stalks and dead fungi surrounded by scraggly, evilly twisted trees with bare boughs. But behind the village is a dismal-looking hill on whose summit is a circle of great stones with another stone at the center. That, without question, is the vile primordial thing V told me about at the N estbat.
The great house lies in the midst of a park all overgrown with curious-looking briars. I could scarcely break through, and when I did the vast age and decrepitude of the building almost stopped me from entering. The place looked filthy and diseased, and I wondered how so leprous a bulk could hang together. It is wooden; and though its original lines are hidden by a bewildering tangle of wings added at various dates, I think it was first built in the square colonial fashion of New England. Probably that was easier to build than a Dutch stone house—and then, too, I recall that Oirck van der Heyl's wife was from Salem, a daugh-
