At the end of the story, what does the narrator say about the swamp and the fort?

The narrator describes the supernatural events, the lightening, and the fire..... Tom is being taken to pay the devil his due.

A countryman, who lived on the border of the swamp, reported that in the height of the thundergust he had heard a great clattering of hoofs and a howling along the road, and running to the window caught sight of a figure, such as I have described, on a horse that galloped like mad across the fields, over the hills, and down into the black hemlock swamp toward the old Indian fort; and that shortly after a thunderbolt falling in that direction seemed to set the whole forest in a blaze.
