You got a link to support your assertion that "witches" were "burned at
the stake" in Salem Mass. ?? I never encountered that history
Long ago I read a thing that was either a play or novella that seemed
like sort of inferior "historical fiction" ---that suggested that ENGLAND inter-

on competition for land and water ----etc, ie some sort of financial jealousy
and grasping for advantage--------that just petered out when it became obvious that it was getting to be an unbridled sort of insanity. Some
influential people began to express doubts, HOWEVER public hangings did continue
in North America for theft of life stock and horses
