SPRINGFIELD, Sept. 14, 1856.

DEAR SIR:—Yours, inviting me to attend a mass-meeting on the 23d inst., is received. It would be very pleasant to strike hands with the Fremonters of Iowa, who have led the van so splendidly, in this grand charge which we hope and believe will end in a most glorious victory. All thanks, all honor to Iowa! But Iowa is out of all danger, and it is no time for us, when the battle still rages, to pay holiday visits to Iowa. I am sure you will excuse me for remaining in Illinois, where much hard work is still to be done.

Yours very truly,

A. LINCOLN. [ [!-- H2 anchor --] ]

AFTER THE DEMOCRATIC VICTORY OF BUCHANAN

FRAGMENT OF SPEECH AT A REPUBLICAN BANQUET IN CHICAGO, DECEMBER 10, 1856.

We have another annual Presidential message. Like a rejected lover making merry at the wedding of his rival, the President felicitates himself hugely over the late Presidential election. He considers the result a signal triumph of good principles and good men, and a very pointed rebuke of bad ones. He says the people did it. He forgets that the "people," as he complacently calls only those who voted for Buchanan, are in a minority of the whole people by about four hundred thousand votes—one full tenth of all the votes. Remembering this, he might perceive that the "rebuke" may not be quite as durable as he seems to think—that the majority may not choose to remain permanently rebuked by that minority.

The President thinks the great body of us Fremonters, being ardently attached to liberty, in the abstract, were duped by a few wicked and designing men. There is a slight difference of opinion on this. We think he, being ardently attached to the hope of a second term, in the concrete, was duped by men who had liberty every way. He is the cat's-paw. By much dragging of chestnuts from the fire for others to eat, his claws are burnt off to the gristle, and he is thrown aside as unfit for further use. As the fool said of King Lear, when his daughters had turned him out of doors, "He 's a shelled peascod" ("That 's a sheal'd peascod").

So far as the President charges us "with a desire to change the domestic institutions of existing States," and of "doing everything in our power to deprive the Constitution and the laws of moral authority," for the whole party on belief, and for myself on knowledge, I pronounce the charge an unmixed and unmitigated falsehood.

Our government rests in public opinion. Whoever can change public opinion can change the government practically just so much. Public opinion, on any subject, always has a "central idea," from which all its minor thoughts radiate. That "central idea" in our political public opinion at the beginning was, and until recently has continued to be, "the equality of men." And although it has always submitted patiently to whatever of inequality there seemed to be as matter of actual necessity, its constant working has been a steady progress toward the practical equality of all men. The late Presidential election was a struggle by one party to discard that central idea and to substitute for it the opposite idea that slavery is right in the abstract, the workings of which as a central idea may be the perpetuity of human slavery and its extension to all countries and colors. Less than a year ago the Richmond Enquirer, an avowed advocate of slavery, regardless of color, in order to favor his views, invented the phrase "State equality," and now the President, in his message, adopts the Enquirer's catch-phrase, telling us the people "have asserted the constitutional equality of each and all of the States of the Union as States." The President flatters himself that the new central idea is completely inaugurated; and so indeed it is, so far as the mere fact of a Presidential election can inaugurate it. To us it is left to know that the majority of the people have not yet declared for it, and to hope that they never will.
