In addition to the American Historical Association and the American Economic Association, a number of allied societies will hold meetings at the same time and place. Among these bodies are the American Political Science Association, the American Statistical Association, the American Sociological Society, the American Association for Labor Legislation, the American Social Science Association, the American Society of Church History, the Bibliographical Society of America, and the Mississippi Valley Historical Association. There will be a Conference of Local and State Historical Societies and a meeting of the Public Archives Commission. The New York State Teachers’ Association will also be in session at Columbia University on these days, and will hold at least one joint meeting with the American Historical Association. There will be meetings of the working committees and boards of the several societies, and a conference of the editors and correspondents of THE HISTORY TEACHER’S MAGAZINE. Such an association of active organizations is a worthy tribute to the work of the two parent societies during the past twenty-five years; but it is not the members of these societies alone which will join in celebrating the anniversary. Public-spirited citizens of New York, national officials, including the President of the United States, and many representatives from foreign states and learned societies abroad will have a part in the general or special programs. It is not possible here to give in detail all the announcements already issued concerning the meetings. For convenience it is necessary to group them into three divisions: Meetings of a general nature, arranged by New York citizens as a recognition of the worth of the associations, and joint public meetings of several societies; meetings of the several societies in which matters of special interest to their own members are discussed; and social meetings and events prepared by the local committees of arrangements in which the liberal hospitality of the city is well shown.
