This rage for road building is beneficent for America, where vast distance is so main a consideration in our domestic politics and trade, inasmuch as the great political promise of the invention is to hold the Union staunch, whose days seemed already numbered by the mere inconvenience of transporting representatives, judges, and officers across such tedious distances of land and water. Not only is distance annihilated, but when, as now, the locomotive and the steamboat, like enormous shuttles, shoot every day across the thousand various threads of national descent and employment, and bind them fast in one web, an hourly assimilation goes forward, and there is no danger that local peculiarities and hostilities should be preserved. 1. But I hasten to speak of the utility of these improvements in creating an American sentiment. An unlooked for consequence of the railroad, is the increased acquaintance it has given the American people with the boundless resources of their own soil. If this invention has reduced England to a third of its size, by bringing people so much nearer, in this country it has given a new celerity to _time_, or anticipated by fifty years the planting of tracts of land, the choice of water privileges, the working of mines, and other natural advantages. Railroad iron is a magician’s rod, in its power to evoke the sleeping energies of land and water. The railroad is but one arrow in our quiver, though it has great value as a sort of yard-stick, and surveyor’s line. The bountiful continent is ours, state on state, and territory on territory, to the waves of the Pacific sea; “Our garden is the immeasurable earth, The heaven’s blue pillars are Medea’s house.” The task of surveying, planting, and building upon this immense tract, requires an education and a sentiment commensurate thereto. A consciousness of this fact, is beginning to take the place of the purely trading spirit and education which sprang up whilst all the population lived on the fringe of sea-coast. And even on the coast, prudent men have begun to see that every American should be educated with a view to the values of land. The arts of engineering and of architecture are studied; scientific agriculture is an object of growing attention; the mineral riches are explored; limestone, coal, slate, and iron; and the value of timber-lands is enhanced.
