Mark Twain's Library of Humour. (Chatto and Windus.) — " Mark
Twain " collects into a volume of somewhat more than seven hundred pages, some hundred and sixty specimens of Ameri- can humour. Brief biographical notices of the writers are pre- fixed to some of the extracts. The first extract is Mr. Clemens's own " Jumping Frog ;" and when we say that C. D. Warner, T. B. Aldrich, Bret Haste, J. R. Lowell, W. D. Howells, Artemus Ward, C. G. Leland, G. W. Cable, Josh Billings, 0. W. Holmes, and E. C. Stedman are among the contributors, our readers will know that there will be plenty to make them laugh. We do not see the name of Max Adeler, whose " Elbow-Room" we are inclined to rank very high in classifying American humour.
