This old thorn of the tariff, which was the cause of so much irritation in the old body politic, is removed forever from the new.  Again, the subject of internal improvements, under the power of Congress to regulate commerce, is put at rest under our system. The power, claimed by construction under the old constitution, was at least a doubtful one; it rested solely upon construction.

“The expansion of the South [from 1800 to 1850] across the Appalachians and the Mississippi River to the fringes of the high plains was one of the great American folk wanderings. Motivated by the longing for fresh and cheap land,… Southerners completed their occupation of a region as large as western Europe. Despitethe variety of the land, . . . the settlers of the Southwest had certain broad similarities. They might be farmers large or small, but most farmed or lived by serving the needs of farmers. . . .
