“We have heard popular orators declaiming to audiences to whose fathers James Otis and Samuel Adams spoke, and whose fathers' cheeks would have burned with shame and their hearts tingled with indignation to hear, that the Declaration of Independence was the passionate manifesto of a revolutionary war, and its doctrine of equal human rights a glittering generality. And finally, throwing off the mask altogether, but still whining to be let alone, we see this system, grown now from seven hundred thousand to four millions of slaves, declaring that it is in a peculiar sense a divine and Christian institution; that it is right in itself and a blessing, not a bane; that it is ineradicable in the soil; that it is directly recognized and protected by the Constitution of the United States; that its rights under that Constitution are to be maintained at all hazards; and haw they are maintained we may see in the slave States, by the absolute annihilation of free speech and by codes of law insulting to humanity and common-sense; and how they are to be maintained in the new States we have seen in the story of Kansas. It declares that, the Congress of the United States being a slave instrument and being also the supreme law of the land, the rights of the slave States are to be protected from injury by the suppression in the free States of what shall be decided by the United States Courts to be incendiary discussion; and at last it openly announces, by its representative leaders in Congress, that if a majority of the people of the United States shall elect a government holding what they allow to have been the principles of the founders of the government upon this question, they will hesitate at no steps to destroy the Union.”

A lecture on 'Books' delivered in 1864; the quoted phrase 'glittering generalities' had been used by Rufus Choate to describe the declaration of the rights of man in the Preamble to the Constitution (The Complete Works of Ralph Waldo Emerson (1903-4) Vol. 10, p. 88, note 1)

1920s, Speech on the Anniversary of the Declaration of Independence (1926)

how can your aching hearts believe it, but this war of four years, so full of doubt and anguish, was infinitely nobler and more glorious than the thirty years of peace before it. Four years more of such peace would have slain the very soul of the nation ; and because the country was still strong enough to tear off that fair and fatal robe of compromise, because she bared her bosom and bravely endured the sharp torture of the knife, to-day the cancer is cut away, and she stands erect, though bleeding, and thanks God for health renewed.

Rev. William Henry Foote, in "Cornstalk, the Shawanee Chief" in The Southern Literary Messenger Vol. 16, Issue 9, (September 1850) pp. 533-540
Context: All savages seem to us alike as the trees of the distant forest. Here and there one unites in his own person, all the excellencies, and becomes the favourable representative of the whole, the image of savage greatness, the one grand character in which all others are lost to history or observation. Cornstalk possessed all the elements of savage greatness, oratory, statesmanship and heroism, with beauty of person and strength of frame. In appearance he was majestic, in manners easy and winning. Of his oratory, Colonel Benjamin Wilson, Senr., an officer in Dunmore's army, in 1774, having heard the grand speech to Dunmore in Camp Charlotte, says — "I have heard the first orators in Virginia, Patrick Henry, Richard Henry Lee, but never have I heard one whose powers of delivery surpassed those of Cornstalk on that occasion." Of his statesmanship and bravery there is ample evidence both in the fact that he was chosen head of the Confederacy, and in the manner he conducted the war of 1774, and particularly by his directions of the battle at Point Pleasant.
