"Look at the mighty Mississippi the Father of Waters—it rises in the nameless snows of North America—runs through twenty-three degrees of latitude, all our own soil, and washes the sides of ten young, flourishing, and powerful States; its tributaries drain the rains that fall in sight of the Atlantic and meet the streams that flow into the Pacific upon the summit of the Rocky Mountains—its broad tides bear on their buoyant bosom the clothing of half of the world, and the fertile valleys, which spread out from its ample banks are capable of producing food for the population of the whole earth for a thousand years to come."
