While the steamboat was conquering western rivers, canals were being constructed that further improved the transportation network. Since the midwestern rivers all emptied into the Gulf of Mexico, they did not provide a direct link with the eastern seaboard. If an artificial waterway could be cut between the great central valley and some navigable stream flowing into the Atlantic, all sections would profit immensely.
Canals were more expensive than roads, but so long as the motive power used in overland transportation was the humble horse, they offered enormous economic advantages to shippers. Because there is less friction to overcome, a team plodding along a towpath could pull a canal barge with a 100-ton load and make better time over long distances than it could pulling a single ton in a wagon on the finest road.

Although canals were as old as Egypt, only about 100 miles of them existed in the United States as late as 1816. Construction costs aside, in a rough and mountainous country canals presented formidable engineering problems. To link the Mississippi Valley and the Atlantic meant somehow circumventing the Appalachian Mountains. Most people thought this impossible.
Mayor DeWitt Clinton of New York believed that such a project was feasible in New York State. In 1810, while serving as state canal commissioner, he traveled across central New York and convinced himself that it would be practicable to dig a canal from Buffalo, on Lake Erie, to the Hudson River. The Mohawk Valley cuts through the Appalachian chain just north of Albany, and at no point along the route to Buffalo does the land rise more than 570 feet above the level of the Hudson. Marshaling a mass of technical, financial, and commercial information and using his political influence cannily, Clinton placed his proposal before the New York legislature. In its defense he was eloquent and farsighted:
As an organ of communication between the Hudson, the Mississippi, the St. Lawrence, the great lakes of the north and west, and their tributary rivers, [the canal] will create the greatest inland trade ever witnessed. The most fertile and extensive regions of America will avail themselves of its facilities for a market. All their surplus. . . will concentrate in the city of New York. . . . That city will, in the course of time, become the granary of the world, the emporium of commerce, the seat of manufactures, the focus of great moneyed operations. . . . And before the revolution of a century, the whole island of Manhattan, covered with habitations and replenished with a dense population, will constitute one vast city.
The legislators were convinced, and in 1817 the state began construction along a route 363 miles long, most of it across densely forested wilderness. At the time the longest canal in the United States ran less than twenty-eight miles!
The construction of the Erie Canal, as it was called, was a remarkable accomplishment. The chief engineer, Benjamin Wright, a surveyor-politician from Rome, New York, had had almost no experience with canal building. One of his chief associates, James Geddes, possessed only an elementary school education and knew virtually nothing about surveying. Both learned rapidly by trial and error. Fortunately, Wright proved to be a good organizer and a fine judge of engineering talent. He quickly spotted young men of ability among the workers and pushed them forward. One of his finds, Canvass White, was sent to study British canals. White became an expert on the design of locks; he also discovered an American limestone that could be made into waterproof cement, a vital product in canal construction that had previously been imported at a substantial price from England. Another of Wright’s proteges, John B. Jervis, began as an axman, rose in two years to resident engineer in charge of a section of the project, and went on to become perhaps the outstanding American civil engineer of his time. Workers who learned the business digging the “Big Ditch” supervised the construction of dozens of canals throughout the country in later years.
The Erie, completed in 1825, was an immediate financial success. Together with the companion Champlain Canal, which linked Lake Champlain and the Hudson, it brought in over half a million dollars in tolls in its first year. Soon its entire $7 million cost had been recovered, and it was earning profits of about $3 million a year. The effect of this prosperity on New York State was enormous. Buffalo, Rochester, Syracuse, and half a dozen lesser towns along the canal flourished.
