"A few years after the Constitution was adopted Alexander Hamilton said to Josiah Quincy that he thought the Union might endure for thirty years. He feared the centrifugal force of the system. The danger, he said, would proceed from the States, not from the national government. But Hamilton seems not to have considered that the vital necessity which had always united the colonies from the first New England league against the Indians, and which, in his own time, forced the people of the country from the sands of a confederacy to the rock of union, would become stronger every year and inevitably develop and confirm a nation. Whatever the intention of the fathers in 1787 might have been, whether a league or confederacy or treaty, the conclusion of the children in 1860 might have been predicted. Plant a homogeneous people along the coast of a virgin continent. Let them gradually overspread it to the farther sea, speaking the same language, virtually of the same religious faith, inter- marrying, and cherishing common heroic traditions. Suppose them sweeping from end to end of their vast domain without passports, the physical perils of their increasing extent constantly modified by science, steam, and the telegraph, making Maine and Oregon neighbors, their trade enormous, their prosperity a miracle, their commonwealth of unsurpassed importance in the world, and you may theorize as you will, but you have supposed an imperial nation, which may indeed be a power of evil as well as of good, but which can no more recede into its original elements and local sources than its own Mississippi, pouring broad and resistless into the Gulf, can turn backward to the petty forest springs and rills whence it flows. 'No, no', murmurs the mighty river, 'when you can take the blue out of the sky, when you can steal heat from fire, when you can strip splendor from the morning, then, and not before, may you reclaim your separate drops in me'. 'Yes, yes, my river,' answers the Union, 'you speak for me. I am no more a child, but a man; no longer a confederacy, but a nation. I am no more Virginia, New York, Carolina, or Massachusetts, but the United States of America'."
