This is the Franklin family plot in the Granary Burying Ground in Boston. Benjamin Franklin's parents are buried here but he is buried in Pennsylvania. This is by far the tallest stone in the cemetery, most of the stones here are very modest.
Franklin adopted a favorite habit of his later years—his daily “air bath.” I have found it much more agreeable to my constitution to bathe in another element, I mean cold air. With this view I rise early almost every morning, and sit in my chamber without any clothes whatever, half an hour or an hour, according to the season, either reading or writing. This practice is not in the least painful, but on the contrary, agreeable.
