Unchanging is the river that gathers the waters of highlands and brings them together into one source, with each mile growing larger, stronger, until it reaches its destination and becomes one with the sea. In this complex and dynamic history, Russell M. Lawson navigates the story of the Piscataqua Valley from Martin Pring in 1603, through the turbulent Indian wars of colonial days, around the volatile American Revolution and into the smooth sailing of the nineteenth-century shipbuilding industry. In Dover, Durham, Exeter and the entire valley, Piscataqua played a major role in the foundation of the United States, all the while surrounded by the river's natural splendor.
