The Ghost of the Headless Horseman

The headless horseman was often seen here. An old man who did not believe in ghosts told of meeting the headless horseman coming from his trip into the Hollow. The horseman made him climb up behind. They rode over bushes, hills, and swamps. When they reached the bridge, the horseman suddenly turned into a skeleton. He threw the old man into the brook and sprang away over the treetops with a clap of thunder.
