CATALOGUE OF THE COLLECTIVE EXHIBIT OF THE AGRICULTURAL EXPERIMENT STATIONS IN THE UNITED STATES AT THE PARIS EXPOSITION OF 1900. The agricultural experiment stations in the United States will be represented at the Paris Exposition of 1900 by a collective exhibit prepared by a committee of the Association of American Agricultural Colleges and Experiment Stations. The members of this committee are H. P. Armsby, director of the Pennsylvania Experiment Station, chairman; W. H. Jordan, director of the New York State Experiment Station; A. W. Harris, president of the University of Maine; M. A. Scovell, director of the Kentucky Experiment Station; and A. C. True, Director of the Office of Experiment Stations. The exhibit has been prepared in cooperation with the United States Department of Agriculture, through the Office of Experiment Stations, and illustrates the methods and results of the work of the stations and of the Office of Experiment Stations by means of objects, charts, photographs, and publications arranged to show the main features of the experiment-station enterprise in this country rather than the work of the individual stations.
