SUMMARY

1. In 1840 the population of the country was 17,000,000, of whom more than a third dwelt west of the Allegheny Mountains.

2. For twenty years there had been much discussion about the disposition of the public lands; but Congress did not give up the plan of selling them for the benefit of the United States.

3. As population increased, the Indians were pushed further and further west. Some went to the Indian Country peaceably. In Georgia and Florida they resisted.

4. As Congress would not sanction a general system of federal improvements, the states built canals and railroads for themselves.

5. The success of those in the East encouraged the Western states to undertake like improvements. But they plunged the states into debt.

6. The period was one of great mechanical development, and many inventions of world-wide use date from this time.

7. The growth of manufactures produced great manufacturing towns, and the increase of artisans and mechanics led to the formation of trades unions.

8. The unrest caused by the rapid development, of the country invited reforms of all sorts, and many—social, industrial, and political—were attempted.
