But, say the Northern States, the Constitution of the United States is a very different thing from the Articles of Confederation. It was formed, not by the States, but by the people of the United States in the aggregate, and made all the States one people, one government. It is not a compact, or league between the States, but an instrument under which they have surrendered irrevocably their sovereignty. Under it, the Federal Government has become the paramount authority, and the States are subordinate to it. We will examine this doctrine, briefly, in another chapter.
