We must remember that we have not only the present but the future to safeguard; our obligations extend even to generations yet unborn. The unassimilated alien child menaces our children, as the alien industrial worker, who has destruction rather than production in mind, menaces our industry. It is only when the alien adds vigor to our stock that he is wanted. The dead weight of an alien accretion stifles national progress. But we have a hope that can not be crushed; we have a background that we will not allow to be obliterated. The only acceptable immigrant is the one who can justify our faith in man by a constant revelation of the divine purpose of the Creator.
