Seven muddy miles transformed a region and a nation

This fascinating account explores the significance of the Chicago Portage, one of the most important—and neglected—sites in early US history. A seven-mile-long strip of marsh connecting the Chicago and Des Plaines Rivers, the portage was inhabited by the earliest indigenous people in the Midwest and served as a major trade route for Native American tribes. A link between the Mississippi River and the Atlantic Ocean, the Chicago Portage was a geopolitically significant resource that the French, British, and US governments jockeyed to control. Later, it became a template for some of the most significant waterways created in the nineteenth and twentieth centuries. The portage gave Chicago its name and spurred the city’s success—and is the reason why the metropolis is located in Illinois, not Wisconsin.
 
A History of the Chicago Portage: The Crossroads That Made Chicago and Helped Make America is the definitive story of a national landmark.

The Engineering Marvel That Saved Chicago
Benjamin Sells
Northwestern University Press, 2017
The Tunnel under the Lake recounts the gripping story of how the young city of Chicago, under the leadership of an audacious engineer named Ellis Chesbrough, constructed a two-mile tunnel below Lake Michigan in search of clean water.

Despite Chicago's location beside the world’s largest source of fresh water, its low elevation at the end of Lake Michigan provided no natural method of carrying away waste. As a result, within a few years of its founding, Chicago began to choke on its own sewage collecting near the shore. The befouled environment, giving rise to outbreaks of sickness and cholera, became so acute that even the ravages and costs of the U.S. Civil War did not distract city leaders from taking action.

Chesbrough's solution was an unprecedented tunnel five feet in diameter lined with brick and dug sixty feet beneath Lake Michigan. Construction began from the shore as well as the tunnel’s terminus in the lake. With workers laboring in shifts and with clay carted away by donkeys, the lake and shore teams met under the lake three years later, just inches out of alignment. When it opened in March 1867, observers, city planners, and grateful citizens hailed the tunnel as the "wonder of America and of the world."

Benjamin Sells narrates in vivid detail the exceptional skill and imagination it took to save this storied city from itself. A wealth of fascinating appendixes round out Sells’s account, which will delight those interested in Chicago history, water resources, and the history of technology and engineering.
