The United States was a new republic in 1817. The generation of its original revolutionaries was fast dying; a second war with Great Britain had recently been settled; and expansionism was the mood of the day. The "children of the founders," as Carol Sheriff calls this first 19th-century American generation, sought to make its mark with engineering projects that would further national growth and prove to Europe that the new nation "played a leading role in God's plan to improve the earthly world." It did so in grand style with the Erie Canal, a huge waterway that linked Atlantic seaports with the Great Lakes. Sheriff's vigorous account of the canal's conception and building makes for an epic story and fascinating reading.
