Mosquito Fest - Mosquito Fest I felt a small tickle on my arm. It turned into a pinching itch.

A Fever in Salem: A New Interpretation of the New England Witch Trials - The author of this book has proposed an intriguing hypothesis regarding the seventeenth-century witchcraft trials in Salem, Massachusetts.

Though this interpretation of the Salem episode is fascinating, the book itself is extremely problematic, fraught with historical errors, inconsistencies, contradictions, conjecture, and a very selective use of the evidence....   [tags: New England Witch Trials] 685 words
