Without his hat he took on an aspect of extreme age which was scarcely visible before, and I wondered if this unperceived mark of singular longevity were not one of the sources of my original disquiet. When he spoke at length, his soft, hollow, and carefully muffled voice not infrequently quavered; and now and then I had great difficulty in following him as I listened with a thrill of amazement and half-disavowed alarm which grew each instant. “You behold, Sir,” my host began, “a man of very eccentrical habits, for whose costume no apology need be offered to one with your wit and inclinations. Reflecting upon better times, I have not scrupled to ascertain their ways and adopt their dress and manners; an indulgence which offends none if practised without ostentation. It hath been my good fortune to retain the rural seat of my ancestors, swallowed though it was by two towns, first Greenwich, which built up hither after 1800, then New York, which joined on near 1830.

So I listened. “To—my ancestor,” he softly continued, “there appeared to reside some very remarkable qualities in the will of mankind; qualities having a little-suspected dominance not only over the acts of one’s self and of others, but over every variety of force and substance in Nature, and over many elements and dimensions deemed more universal than Nature herself. May I say that he flouted the sanctity of things as great as space and time and that he put to strange uses the rites of sartain half-breed red Indians once encamped upon this hill? These Indians showed choler when the place was built, and were plaguey pestilent in asking to visit the grounds at the full of the moon. For years they stole over the wall each month when they could, and by stealth
