Book excerpt: Though best known for his caustic newspaper columns, H. L. Mencken's most enduring contribution to American literature may be his autobiographical writings, most of which first appeared in the New Yorker. In Happy Days, Mencken recalls memories of a safe and happy boyhood in the Baltimore of the 1880s and celebrates a way of life that he saw swiftly changing—from a time of straw hats and buggy rides to locomotives and bread lines.
