There will be other crises in the national history which will make other demands for the fullest and most unselfish contribution to the national interest. No generation will be denied its opportunity, will be spared its duty, to put forth its best efforts. We devoutly hope that these contributions will not be demanded upon the field of battle. But they will be just as truly needed, just as urgently summoned, in the activities of peace, the efforts of industry, the performance of all the obligations of citizenship. We can not go out from this place and occasion without refreshment of faith and renewal of confidence that in every exigency our Negro fellow citizens will render the best and fullest measure of service whereof they are capable.
