II.

Along the southern tier of the great States which form the American Republic, whose gigantic structure and almost supernatural vigor already overshadow and animate the older civilizations of the world, we observe vast extents of level and alluvial lands and deltas, or "rather a series of littoral bands of remarkable disposition," which the ocean left when receding from the mountain shores of the interior to its present limits, or which slowly and gradually emerged from their watery bed in the upheavals during the long intervals of the earth's ages.

This immense territory, stretching from the Potomac to the Rio Grande, and hardly broken throughout this long distance by undulations of the soil, embraces more than six hundred thousand square miles--an extent greater than that of France and the States of the Germanic Confederation combined. Eight millions of human souls inhabit the one, whilst one hundred millions people the other. Ignorance and brutality darken the one, intelligence and humanity illuminate the other.
