I live in Nelson, NH. Just found a reference to Ruth Smith in a book by a local author, Newt Tolman ("North of Monadnock", published 1961), p 27. Two paragraphs referring to her. Starts "Some time ago we drove across the river to visit Ruth Smith, who has written some good things, among them an inspired book called White Man's Burden. Ruth is a real old Vermonter, having moved there from Kansas twelve years ago."
