While I'm glad to see Clemens running around on tleevision (I can't backspace, so bear with my fumbling fingers), I had a queasy feeling after watching the Star Trek: The Next Generation episodes with the crew in the 19th century ("Time's Arrow," parts 1 and 2). SLC appears with a full head of white hair and a mustache, the icon most people know and love . However, Clemens never returned to San Francisco, the setting of the story, after 1868 (explicitly mentioned in David Carkeet's _I Been There Before_, p. 69). He wold have been 33 at the time, not white with age... Robert Dagnall
