These tales, of course, are obsolete and ridiculous; because they come down from very old times. Dunwich is indeed ridiculously old—older by far than any of the communities within thirty miles of it. South of the village one may still spy the cellar walls and chimney of the ancient Bishop house, which was built before 1700; whilst the ruins of the mill at the falls, built in 1806, form the most modern piece of architecture to be seen. Industry did not flourish here, and the Nineteenth Century factory movement proved short-lived. Oldest of all are the great rings of rough-hewn stone columns on the hilltops, but these are more generally attributed to the Indians than to the settlers. Deposits of skulls and bones, found within these circles and around the sizable table-like rock on Sentinel Hill, sustain the popular belief that such spots were once the burial-place's of the Pocumtucks; even though many ethnologists, disregarding the absurd improbability of such a theory, persist in believing the remains Caucasian.
