In "Mark Twain and His World" Justin Kaplan disputed Twain and Gillis's story about the California duel with James Laird. He states that the antidueling statute was an invention of Twain's. Hadn't heard that before. What is the history of the antidueling statute in Nevada Territory, 1864? Did it exist? Also, Kaplan contradicts the Isaiah Seller's story for the origin of the name "Mark Twain" Kaplan suggests the name originated in Nevada when barkeeps would mark up two drinks on credit. Opinions?
