In the newer states particularly, but in the older states also, there had grown up a new conception of the dignity and permanence of the National Union. That which had been originally regarded as a doubtful venture had little by little come to be looked upon as a thing established and glorious. The national idea had taken a new and deeper hold upon men's minds and affections. Vast material and moral interests had grown into sturdy self-consciousness under its beneficent rule. That Union which had been entered upon with so much doubt and hesitation and with so many precautionary stipulations had become one of the great nations of the earth, strong at home and everywhere respected abroad. It had a history in war and peace which was a precious possession of all the people alike. Proud, loving memories clustered about the story of its career. The victories of New Orleans, and Buena Vista, and Chapultepec, the sea conquests of Porter and Perry and the rest, had been added to the stories of Lexington, Concord, Bunker Hill, Trenton, Camden and Yorktown, as fireside tales with which the grandfathers made the eyes of a younger generation of Americans glisten with patriotism. And achievements of peace equally notable--stories of what Morse, Henry, Fulton, Peter Cooper, Daniel Boone, Bowie, Kit Carson, Fremont, Sam Houston, General Gaines and a multitude of others had accomplished--were equally stimulating to the pride and patriotism of the youth of the thirty-three states. And there were heroic tales told of Indian wars in which Andrew Jackson and William Henry Harrison, Sam Dale, the Mississippi Yagers, Col. Dick Johnson, and other veritable heroes of romantic daring had figured. All these and scores and hundreds of other tales of patriotic heroism were then familiars of the fireside as illustrations of American pluck and American achievement. There was the country's expansion, too, to glory in. The Louisiana purchase had added an empire of vast extent and of inestimable productive possibilities to the national domain, the development of which, even before 1861, was a romantic wonder story of history. The Mexican war had brought with it another accession of incalculably rich territory such as no nation in all history except our own had ever added at a single stroke to its domain.
