Canals and railroads, 1840 map

  Start of a Trend
The Erie Canal is so successful that it immediately sparks imitators.  The Erie and Ohio Canal links the Ohio River to the Great Lakes, which connects with the Erie Canal and Hudson River to complete the all-water route from the Midwest to eastern ports.  Meanwhile, railroads are the new thing on the East Coast. Early lines run from Boston to Albany, and from New York to Philadelphia, reaching Pennsylvania coalfields.

Steamboats and steamboat stops, 1840 map

  Faster than Barges
Cargo on canals is carried on special barges designed to operate in narrow, shallow channels, pulled by horses or mules. Steamboats are used everywhere else, powered by early steam engines, which are so large they are only practical for large vessels. The BLUE dots indicate steamboat landings, where are located everywhere there is enough water to float a steamboat. Steamboats work every major river, and the entire southern coast, including all the way around Florida to Charleston.


Cotton plantations, 1840 map

  Cotton Replaces Indians
The Deep South offers ideal conditions for the cultivation of cotton, which loves hot weather. This is made possible by the combination of two new technologies, the cotton gin and the powered weaving loom. But just as important is the ability of slaves to work all day outdoors under the grueling sun, in conditions which Whites find difficult to tolerate. Now we see why the Indians had to go. Southern planters need the land for cotton, which has already displaced tobacco as the big money-maker in the South.


Texas and Mexican War, 1846-48 map

  Mexican War Payoff
The war with Mexico is triggered by events in Texas, where independent ranchers briefly establish the Republic of Texas in 1836. Mexico continues to claim ownership, but American settlers eventually coax Congress into annexing the territory, in 1845. Within a year, border clashes turn into a full-blown war, which lasts two years, and is fought entirely in Mexican territory. When it's over, America owns not only Texas, but also a huge new tract of western land, including all-important California.


Cities at rail terminals, 1850 map

  Railroads Sprout Cities
The canal boom is just beginning to crest when it's blind-sided by an even more transformational technology. Railroads. In just 10 years, the rail system has exploded across the country, from east to west, and north to south. Every important supply center now has its own rail terminal, which turbo-charges growth everywhere, and greatly accelerates the movement of pioneers westward. Cargo can now be shipped almost anywhere, including the many areas not serviced by navigable rivers or canals.


Mature canal era, 1850 map

  Boom Turns to Bust
The canal-building era is now fully mature, as canals have spread all the way to Chicago. Pennsylvania's canal system is the most comprehensive, linking the state's eastern and western regions, and connecting with Chesapeake Bay. Other states establish new links between Lake Erie and the Ohio River.  By now, however, canals are going head-to-head against railroads, in a competition they cannot win. Within 10 years, the faster and more versatile railroads will largely displace canals.
