Questions for Map 1

1. In 1821, what were the western states?

2. Given that rivers flow towards the ocean, in which direction do the major rivers east of the Appalachian Mountains flow? What about the rivers west of the Appalachians? Why might this create a problem for cross-country trade?

Did You Know?
George Washington's dream of connecting the eastern states with the western frontier led to the creation of the Patowmack Company. Locks were built around unnavigable parts of the Potomac River for improved commerce. The C&O Canal inherited the right of way after the Patowmack Company's demise.
