How Mark Twain turned frontier humor into literature:

It wasn’t easy. The notion that literature could emerge from the frontier’s barbaric yawp encountered violent resistance from America’s literary establishment. It didn’t help that tall tales abounded in vulgarity, drunkenness, and depravity, not to mention perversions of proper English that would make a schoolteacher gasp. Proving the literary power of the frontier would be a central part of Twain’s legacy, and a pie in the face of the New England dons who had dominated the country’s high culture for much of the nineteenth century. He wasn’t immune to wanting their approval, but he came from a very different tradition. His ear hadn’t been trained at Harvard or Yale; it was tuned to the myriad voices of slaves and scoundrels, boatmen and gamblers.
