Originally published in 1947, The Everglades was one of those rare books, like Uncle Tom's Cabin and Silent Spring, to have an immediate political effect: it helped draw public attention to a vast and little-known area that South Florida developers had deemed a worthless swamp and were busily draining, damming, and remaking, and it mustered needed public support for President Harry Truman's controversial order, later that year, to protect more than 2 million acres as Everglades National Park. Remote and seldom visited, the Everglades nonetheless had a rich human history: several Native American peoples, Spanish explorers, French and English pirates, runaway slaves, and Anglo trappers and fishermen all came to this limestone basin and made their lives among its slowly moving water and fast-growing sawgrass.
