And do not forget that Twain was born the year that Comet Halley made one of its famous returns to the vicinity of Earth in 1835, and died when it came back 75 years later in 1910, as he thought he would. Does this mean that another author on the level of Mark Twain was born in 1986 and we are now awaiting his emergence? :^) At least he will live to see the year 2061. Does anyone have a list and brief description of the works that Twain wrote regarding astronomy and cosmological thought? Larry Klaes EJASA Editor, Astronomical Society of the Atlantic
