From The Museum of Hoaxes:
It was a fascinating little blurb. So fascinating that many other papers soon reprinted it. The only problem was that not a word of it was true. It had been written by a young man named Samuel Clemens (better known later as Mark Twain) who was a recent employee of the Territorial Enterprise. (He had arrived in Nevada in 1861 hoping to make his fortune as a miner, but having failed at that endeavor, accepted a job at the newspaper.)
Twain later admitted that he was surprised at how many people were fooled by his story. It was his first attempt at a hoax, and when he penned it he had considered it “a string of roaring absurdities.” But once he realized how well his deception had succeeded, he admitted feeling a “soothing secret satisfaction.”
