The scene of my excavations would alone have been enough to unnerve any ordinary man. Baleful primal trees of unholy size, age, and grotesqueness leered above me like the pillars of some hellish Druidic temple; muffling the thunder, hushing the clawing wind, and admitting but little rain. Beyond the scarred trunks in the background, illumined by faint flashes of filtered lightning, rose the damp ivied stones of the deserted mansion, while somewhat nearer was the abandoned Dutch garden whose walks and beds were polluted by a white, fungous, fetid, overnourished vegetation that never saw full daylight. And nearest of all was the graveyard, where deformed trees tossed insane branches as their roots displaced unhallowed slabs and sucked venom from what lay below. Now and then, beneath the brown pall of leaves that rotted and festered in the antediluvian forest darkness, I could trace the sinister outlines of some of these low mounds which characterized the lightning-pierced region. History had led me to this archaic grave. History, indeed, was all I had after everything else ended in mocking Satanism. I now believed that the lurking fear was no material thing, but a wolf-fanged ghost that rode the midnight lightning. And I believed, because of the masses of local tradition I had unearthed in my search with Arthur Munroe, that the ghost was that of Jan Martense, who died in 1762. That is why I was digging idiotically in his grave. The Martense mansion was built in 1670 by Gerrit Martense, a wealthy New Amsterdam merchant who disliked the changing order under British rule, and had constructed this magnificent domicile on a remote woodland summit whose untrodden solitude and unusual scenery pleased him. The only substantial disappointment encountered in this site was that which concerned the prevalence of violent thunderstorms in summer. When selecting the hill and building his mansion, Mynheer Martense had laid these frequent natural outbursts to some peculiarity of the year; but in time he perceived that the locality was especially liable to such phenomena. At length, having found these storms injurious to his head, he fitted up a cellar into which he could retreat from their wildest pandemonium.
