One spring evening in 1896, a prominent Pennsylvanian named Hamilton Disston blew his brains out in a bathtub. He had become gravely depressed after depleting his inheritance on a grandiose campaign to drain 4 million acres of Florida swamp known as the Everglades. Although Disston died believing himself a failure, he was later proven a pioneer and an inspiration. In the years that followed, one version or another of his rapacious fantasy was pursued by legions of avaricious speculators--land developers, bankers, railroad barons, real-estate promoters, citrus growers, cattle ranchers, sugar tycoons and, last but not least, the politicians they owned.
