The University therefore, has a double duty. On the one hand it must aid in the improvement of the general economic and social environment. It must help on in the work of scientific discovery and of making such conditions of existence, economic, political and social, as will produce more fertile and responsive soil for a higher and better life. It must stimulate a wider demand on the part of the public for right leadership. It must extend its operations more widely among the people and sink deeper shafts through social strata to find new supplies of intellectual gold in popular levels yet untouched. And on the other hand, it must find and fit men and women for leadership. It must both awaken new demands and it must satisfy those demands by trained leaders with new motives, with new incentives to ambition, with higher and broader conception of what constitute the prizes in life, of what constitutes success. The University has to deal with both the soil and sifted seed in the agriculture of the human spirit. Its efficiency is not the efficiency which the business engineer is fitted to appraise. If it is a training ship, it is a training ship bound on a voyage of discovery, seeking new horizons. The economy of the University's consumption can only be rightly measured by the later times which shall possess those new realms of the spirit which its voyage shall reveal. If the ships of Columbus had engaged in a profitable coastwise traffic between Palos and Cadiz they might have saved sail cloth, but their keels would never have grated on the shores of a New World. The appeal of the undiscovered is strong in America. For three centuries the fundamental process in its history was the westward movement, the discovery and occupation of the vast free spaces of the continent. We are the first generation of Americans who can look back upon that era as a historic movement now coming to its end. Other generations have been so much a part of it that they could hardly comprehend its significance. To them it seemed inevitable. The free land and the natural resources seemed practically inexhaustible. Nor were they aware of the fact that their most fundamental traits, their institutions, even their ideals were shaped by this interaction between the wilderness and themselves. American democracy was born of no theorist's dream; it was not carried in the Susan Constant to Virginia, nor in the Mayflower to Plymouth. It came stark and strong and full of life out of the American forest, and it gained new strength each time it touched a new frontier. Not the constitution, but free land and an abundance of natural resources open to a fit people, made the democratic type of society in America for three centuries while it occupied its great empire.
