Thirdly, even within the white world, migrations of lower human types like those which have worked such havoc in the United States must be rigorously curtailed. Such migrations upset standards, sterilize better stocks, increase low types, and compromise national futures more than war, revolutions, or native deterioration. Such are the things which simply _must_ be done if we are to get through the next few decades without convulsions which may render impossible the white world's recovery. These things will not bring in the millennium. Far from it. Our ills are so deep-seated that in nearly every civilized country racial values would continue to depreciate even if all three were carried into effect. But they will at least give our wounds a chance to heal, and they will give the new biological revelation time to permeate the popular consciousness and transfuse with a new idealism our materialistic age. As the years pass, the supreme importance of heredity and the supreme value of superior stocks will sink into our being, and we will acquire a true _race_-consciousness (as opposed to national or cultural consciousness) which will bridge political gulfs, remedy social abuses, and exorcise the lurking spectre of miscegenation. In those better days, we or the next generation will take in hand the problem of race-depreciation, and segregation of defectives and abolition of handicaps penalizing the better stocks will put an end to our present racial decline. By that time biological knowledge will have so increased and the popular philosophy of life will have been so idealized that it will be possible to inaugurate positive measures of race-betterment which will unquestionably yield the most wonderful results. Those splendid tasks are probably not ours. They are for our successors in a happier age. But we have our task, and God knows it is a hard one--the salvage of a shipwrecked world! Ours it is to make possible that happier age, whose full-fruits we shall never see. Well, what of it? Does not the new idealism teach us that we are links in a vital chain, charged with high duties both to the dead and the unborn? In very truth we are at once sons of sires who sleep in calm assurance that we will not betray the trust they confided to our hands, and sires of sons who in the Beyond wait confident that we shall not cheat them of their birthright. Let us, then, act in the spirit of Kipling's immortal lines: "Our Fathers in a wondrous age, Ere yet the Earth was small, Ensured to us an heritage, And doubted not at all That we, the children of their heart, Which then did beat so high, In later time should play like part For our posterity. * * * * *
