This book is fiction. Unfortunately it is presented with a lot of details that might make you think it is true, and it is cataloged as History / Natural History.An excellent analysis of some of his "facts" can be found here, along with some good reasons why this kind of writing is misleading:http://www.boudillion.com/witch/mitchell.htmJohn Hanson Mitchell has a recent book about the natural history of Boston. How much of that one is also "made up?"
