David Dunbar (colonel)

Fort Frederick in Maine. In 1734, in an attempt to enforce the Broad Arrow policy of the Massachusetts Charter governing the protection of white pine trees of diameter greater than 24 inches for use in the making of ship masts, Dunbar and a group of his enforcers were run out of Exeter, New Hampshire. Dunbar had been interrogating townspeople about a large supply of white pine logs floating in a mill pond and about the ownership of the nearest timber mill.^[1][2][3]
