from her deep-embowelled mines; all that enterprise can accomplish with exhaustless means, the best facilities, and the most stupendous objects; and all that genius can create, when stimulated by the richest rewards and the freest opportunities for untrammelled exertion, will supply us with the means and materials for an almost infinite variety of pursuits and occupations; but, at the same time, the essential unity of our complex institutions will be maintained, and their power extended and exalted by the homogeneity and uniformity of social conditions which will prevail more and more with the lapse of years and the succession of generations. The blood of all kindred races will be mingled with advantage in the veins of the cosmopolitan American; religions will be harmonized and unified by the most fraternal liberality and unbounded toleration; and the common enlightenment of the whole people by means of universal education will exalt them to a condition of unexampled power and prosperity. Just as dissensions among the States tend to weaken the central power, their uniform and cordial cooeperation will give immense strength to the whole. Nor will this increase of power be at all dangerous, because it will be only the legitimate consequence of the greater progress and prosperity of the States themselves. To whatever height the greatness of the Union may attain, it will be determined exactly by that of the States which compose it--the pyramid of its power being made up of theirs, which are but the enduring blocks of which the mighty structure is built.
