I was grateful to receive a note from a reader of twainsgeography.com on a mispelled location. My e-mail reply was returned as a user unknown from a service called nevermind.com. There is a small island, named Procida, that Mark Twain visited. I had it as Procidia. In case this reader is also a reader of Twain-L I'd like to express my thanks for the headsup.
