I am putting together an online edition of W. D. Howells's My Mark Twain with additional criticism not included in that volume (it's online at http://www.boondocksnet.com/twaintexts/mmt/). So far, I've added his speech at the Nov. 1900 Lotos Club Welcome Home dinner, the introduction to Mark Twain's Speeches, and his Editor's Easy Chair reviews of Mark Twain: A Biography and Mark Twain's Letters. I also know of his Feb. 1917 mention of The Mysterious Stranger introducing a broader discussion of humorists and satire. Does anyone know of other significant writings, speeches, or interviews about Twain that were not included in the 1910 book? Thanks. Jim Zwick
