We have an exchange of letters between John and one Harold L. James, Chief Geologist at the Department of the Interior. It seems that Richard Toronto had requested some “magnetic fault maps” from the Department of the Interior, and received a cranky reply from one John Henderson. I assume the book Henderson is rude about is UFOs: Operation Trojan Horse. John replies to Harold L. James, doing his best to separate himself from the “paranoid bunch” of UFO buffs.
I also assume the Richard Toronto here is the former editor of Shavertron, and the author of several fine books on that fascinating character, Richard Shaver. Read his books!
