From even the greatest of horrors irony is seldom absent. Sometimes it
enters directly into the composition of the events, while sometimes it
relates only to their fortuitous position among persons and
places. The latter sort is splendidly exemplified by a case in the
ancient city of Providence, where in the late forties Edgar Allan Poe
used to sojourn often during his unsuccessful wooing of the gifted
poetess, Mrs.  Whitman. Poe generally stopped at the Mansion House in
Benefit Street--the renamed Golden Ball Inn whose roof has sheltered
Washington, Jefferson, and Lafayette--and his favorite walk led
northward along the same street to Mrs. Whitman's home and the
neighboring hillside churchyard of St. John's, whose hidden expanse of
Eighteenth Century gravestones had for him a peculiar fascination.

    Now the irony is this. In this walk, so many times repeated, the
    world's greatest master of the terrible and the bizarre was
    obliged to pass a particular house on the eastern side of the
    street; a dingy, antiquated structure perched on the abruptly
    rising side hill, with a great unkempt yard dating from a time
    when the region was partly open country. It does not appear that
    he ever wrote or spoke of it, nor is there any evidence that he
    even noticed it. And yet that house, to the two persons in
    possession of certain information, equals or outranks in horror
    the wildest fantasy of the genius who so often passed it
    unknowingly, and stands starkly leering as a symbol of all that is
    unutterably hideous.

    The house was--and for that matter still is--of a kind to attract
    the attention of the curious. Originally a farm or semi-farm
    building, it followed the average New England colonial lines of
    the middle Eighteenth Century--the prosperous peaked-roof sort,
    with two stories and dormerless attic, and with the Georgian
    doorway and interior panelling dictated by the progress of taste
    at that time. It faced south, with one gable end buried to the
    lower windows in the eastward rising hill, and the other exposed
    to the foundations toward the street. Its construction, over a
    century and a half ago, had followed the grading and straightening
    of the road in that especial vicinity; for Benefit Street--at
    first called Back Street--was laid out as a lane winding amongst
    the graveyards of the first settlers, and straightened only when
    the removal of the bodies to the North Burial Ground made it
    decently possible to cut through the old family plots.
