the unique character of the river I had begun to explore. Its source lies cupped more than 4,000 feet high in the Adirondacks; its valley ends 500 feet beneath the Atlan tic. Yet it accomplishes this dive with out apparent effort. It has its rapids and waterfalls, but they are not extraordi nary (page 398). The river as most peo ple know it is broad, deep, and so placid that it scarcely knows which way to go; half the time it runs upstream. Algon quian Indians called it "the river that flows two ways." Ocean tides sweep up to Troy. In this 150-mile stretch the Hudson really is no river at all but an inlet of the sea. At Al bany's docks ocean vessels rise and fall on a 41/2-foot tide. Few rivers of North America equal the Hudson as a corridor of history. On its shore was founded what was to become one of the world's three largest cities, rivaled today only by Tokyo and London. Three wars bloodied the Hud son-Champlain Valley, stretching from New York to Montreal: the French and Indian War, the Revolution, and the War of 1812. Here, in the War of Independence, the British made their unsuccessful attempt to divide the rebellious Colo nies; here the war reached its turning the continental shelf. From a plane, the channel shows as a dark stripe in the sea.
