But there is something else pertinent to be learned here. That the north generally found out only what Webster said in the debate for his side, and never even heard of what was said on the other, and that the south became at once familiar with both speeches, proves that each section had already formed its own belonging and independent public, and that the southern public kept attentive watch upon all affairs of fact or opinion interesting the other, while the northern public knew hardly anything at all of the south. A large percentage of the southern leaders had studied in northern schools and colleges. In this and many other ways they had been instructed as to the north. Such instruction contributed very greatly to southern supremacy in the federal government until the election of Lincoln. We can now see that the powers in charge, as a part of their work, made the great northern public, which, as Lincoln observed, was to be the savior of the union, stop its ears to all anti-union sentiments or arguments. How else can you understand it that the ante-bellum notices of Webster, the memoir by Everett, the different utterances of Choate, and many, many other sketches, are so utterly dumb as to Calhoun's great reply? And is not the same dumbness of Curtis, Von Holst, and McMaster, writing after the war, due to the survival in the north of the old constraint? a constraint so powerful that, while Mr. Henry Cabot Lodge, in 1883, did concede just a little to Calhoun, he stopped far short of the full justice that I believe he would now render were he to traverse the ground again. We must now go beyond what we have already hinted, and show you plainly how both the union men and the State-rights men assumed untenable premises, and how the south, maintaining a cause foredoomed, vanquished in the forum of discussion her adversary, maintaining the side which fate had decreed must win. In no other way can the reader be better made to understand the incalculable potency of the forces which preserved the American union after its orators and advocates had all been discomfited; and in no other way can he better learn what principles are to be invoked if he would grasp the real essence of the union. We emphasize the material and cardinal mistake of the union men, thus phrased by Webster in the speech we have discussed: "Whether the constitution be a compact between States in their sovereign capacities, is a question which must be mainly argued from what is contained in the instrument itself."
