In the book _Mark Twain Drinking_, (1936) Frank Kelsey provided an account of the vist that Twain made along with Charles Klaproth (of Elmira) to the Old Crow distillery in Kentucky. Other sources spell Klaproth's name as Klapproth. Old Crow advertisements displayed it as Klaproth. Questions: 1. Is there a more accurate source that documents Twain's visit to the Old Crow distillery in Kentucky? 2. What was the date of the visit to the Old Crow distillery? Before or after spring of 1880 when Twain was corresponding with Frank Fuller about investing in a "whisky mill"? 3. What is the correct spelling of Klaproth/Klapproth? Thanks, Barb
