VAN NORMAN, president, World's Dairy Congress Association (Inc.). Secretary, SAM H. GREENE, secretary, California Dairy Council. MEMORIAL CONTINENTAL HALL, Washington, D. C., Tuesday, October 2, 1923—10 a. m. The delegates and guests arose and applauded as President Van Norman of the congress and the Hon. Charles Evans Hughes, Secretary of State, came upon the platform. (The Marine Band played the national anthem.) Rev. Dr. JAMES SHERA MONTGOMERY. Almighty God, Father of the races of men, lift upon us all the light of Thy holy countenance. May we ever esteem Thee to be the Source of every good and perfect gift. Regard in great mercy and direct with divine wisdom the nations of the earth. Bless, Almighty God, the people of all lands and hasten the day when the troubled world will rest in peace and in Christian fraternity. We ask Thy blessing upon our own dear country. Establish, more and more, the great fundamentals of our civilization. Direct and bless with great wisdom the President of these United States. We ask the blessing of the common Heavenly Father of us all upon this assembly. Bless with divine mercy all families that are separated. Be there as well as here, and here as well as there. Direct the deliberations of this body. Establish Thou the work of their hands, the work of their hands establish Thou it, through Jesus Christ, our Lord. Amen. (President Van Norman was greeted with applause as he arose to open the meeting) President VAN NORMAN. It is indeed a happy day for those of us who have devoted most of our active adult life to the science, teaching, and business growing out of the rearing and care of that faithful servant of humanity, the dairy cow, when we can gather here in this beautiful hall in our Capital City as representatives of an international brotherhood, having a common interest in so humble a subject, and yet one so important. It is indeed a happy day when our interests have risen to the dignity which permits an invitation authorized by the Congress of the United States, extended in the name of the Chief Executive of our Nation, to all the nations of the world. It is a happy day that gives us the privilege of welcoming to our land the representatives of other lands by the Secretary of State of our Nation, our beloved Charles Evans Hughes. (The delegates and guests arose and applauded.) ADDRESS OF WELCOME. CHARLES EVANS HUGHES, LL. D., Secretary of State, United States of America. Mr. President, members of the congress, ladies and gentlemen: 1 esteem it a high privilege to have this opportunity of speaking a word of cordial greeting to the members of the congress and especially to those from other lands who have honored us by accepting our invitation to consider the interests of this basic industry with its vital relation to human welfare. When I came in, Secretary Wallace welcomed me to his domain, and there may be in your minds just a thought of surprise at my being afforded the opportunity to speak this word of welcome, but perhaps you may reflect that diplomacy is the art of the distribution of the milk of human kindness. [Applause.] And it is most injurious when it is unwholesome. [Laughter and applause.] I take pleasure in noting the fact, to which the president has called attention, that it was the people of the United States, acting through their representatives in the National Legislature, who, mindful not only of their domestic exigencies but intent upon international cooperation of a wise and fruitful character in this promising field, initiated the movement for this meeting. Those of you who have come from other nations (I believe there are upward of 40 represented in this assembly) will find not only a most hearty welcome on the part of our people but, I believe, a most favorable atmosphere for this cooperative effort. Washington, as you know, has been the scene of many important negotiations for the formulation of treaties, for the cementing of the bonds of international friendship, for the giving of assurances of peaceful adjustment. It was only two years ago that in this very hall there met a most important conference for the purpose of limiting naval armaments [applause] and of assuring peace by removing suspicion and distrust; but we can not fail to recognize that these aims, important as they are, constant and earnest as may be our endeavor to achieve them, are not the ultimate aims. The ultimate aims lie beyond these. Peace itself is not a goal-not an ultimate goal, but an opportunity. Limitation of armament, assurances of good will, the maintenance of national security and of the conditions of national fellowship merely open the way to those endeavors by which we may seek to raise the standard of human living and make conditions better throughout the world for human beings. That is our ultimate goal, and it is a great pleasure to come in contact with an endeavor of this sort, representing the kind of international cooperation which we could have on every hand if only we had the assurance of peace and amity which would enable us to work together for the common good of our peoples. [Applause.] I like to think of one aspect of this gathering-its most important aspect, perhaps and to emphasize it. That is of the sort of international cooperation which affords the opportunity for exchanging information, of the results of research, making known what has been accomplished by expert investigators, by producers and distributors. In this way we not only have the opportunity for the pleasant intercourse of friends and those who have the unifying sentiment of common work and ideals, but we give to each other the benefit of what is being accomplished in these great experiment stations of human endeavor. Our peoples are not formed simply in political units; our countries are great laboratories of human experimentation for the purpose of attaining ends which are necessary to all our peoples. What a misfortune it is that we are, to such an extent, held aloof in our separate activities, and that we can not more freely have these interchanges. It is in meetings like this that you have the clearing houses of expert information, that you are enabled to chart the ways of progress. And, after all, what is the fundamental consideration? The fundamental consideration is public health-and you have in your work the most direct and vital relation to it. May I quote the words of the great philosopher, the great orator who illumined every subject that he touched, Cicero, who said, "Men approach most nearly to the gods in their efforts to protect human health." So, I find in turning from the offices of diplomacy to welcome you to this most important and helpful effort, a peculiar sense of privilege. What an enormous amount of time we give to establishing and maintaining the machinery of Government, to the necessary activities of politics, in order that we can have at last a small margin of time and a little opportunity for the real efforts to benefit human beings. [Applause.] Here all that we have accomplished in the State Department, all that is being done in the Halls of Congress, all that is being done to give us a society well organized, stable, and prosperous, finds a focus in the intelligent effort directed immediately to human life, to health, giving us the benefit of experimentation, not only from an economic point of view but with respect to the wise and beneficial sort of public regulation which may safeguard life and health without interfering unnecessarily with individual initiative and opportunity. I congratulate you upon this gathering; I have no doubt that out of it will come improved methods, higher knowledge; but in addition to all, and better than all, fresh inspiration for the best sort of international cooperation and for further meetings like these with a constantly increasing usefulness. [Applause.] President VAN NORMAN. There existed for some years before the war an International Dairy Federation. Since the plans for this congress were conceived, that organization has been reestablished. Its president, having expected to be here, unfortunately, at the last moment, found it impossible to come. He has therefore imposed upon the delegate from France the duty of presenting in his name his words of response to an address, the words of which he could not know, but the spirit of which he undoubtedly anticipated. I have the pleasure of presenting to you now, Prof. Charles Porcher, of Lyons, France, who will present President Maenhaut's greeting. (The delegates arose and applauded.) |
