Scholars at the University of California, Berkeley have uncovered and authenticated a cache of stories written by Mark Twain when he was a 29-year-old newspaperman in San Francisco. Many of the stories are 150 years old.
Twain wrote some of the letters and stories at the San Francisco Chronicle when it was called the San Francisco Dramatic Chronicle, where his job included writing a 2,000-word dispatch every day and sending it off by stagecoach for publication in the Territorial Enterprise newspaper in Virginia City, Nevada.
His topics range from San Francisco police – who at one point attempted, unsuccessfully, to sue Twain for comparing their chief to a dog chasing its tail to impress its mistress – to mining accidents.
