In response to Susanna Ashton's question: you can search Twain's works at the "Mark Twain in His Times" site maintained by Stephen Railton. The address is http://etext.virginia.edu/railton/index2.html Another good place to search (perhaps even better, in fact) is the "Twain's World" CD-ROM, which, with shipping charges, can be obtained from Amazon.com or Barnes & Noble for about $20. However, if you don't know exactly what you're looking for, electronic searching may not be the answer. Jim Leonard
