This battle yell, this impetuous charge after charge until the field is won, marks the fighting of the Americans at King's Mountain--all of them southerners; and it is another weighty proof of the early coalescence of the south as a community on its way to independence. Many other contrasts could be suggested. Think over the foregoing. They are the respective effects of two different causes,--a free-labor nationalization above, and a slave-labor nationalization below, Mason and Dixon's line. The latter--its origin and course--is the especial subject of this chapter. I believe that the proofs marshalled above demonstrate to the fair and unprejudiced reader that southern nationalization commenced before the making of the federal constitution, and afterwards went directly on, gathering force and power all the while, until it culminated in "A storm-cradled nation that fell." CHAPTER V AMERICAN NATIONALIZATION, AND HOW IT MADE THE BOND OF UNION STRONGER AND STRONGER Greece was going down in her contest with Macedon when she gave the world to come the Achæan league, the first historical example of full-grown federation. As Freeman says of such a federal government: "Its perfect form is a late growth of a very high state of political culture."[27] This historian thus summarizes its essentials: "Two requisites seem necessary to constitute federal government in this its most perfect form. On the one hand, each of the members of the union must be wholly independent in those matters which concern each member only. On the other hand, all must be subject to a common power in those matters which concern the whole body of members collectively."[28] No author has yet shown a better-considered and more accurate appreciation of the benefits to different communities of federal union. But the islander could not conceive--even at the centre of the British empire spread over the world--the advanced phase of Anglo-Saxon federation in America and Australia, which for want of a better name we may call, using a grand word of our fathers, continental federation.
