With this the last issue of the IHD Bulletin, I should like to do several things. First and most important, I want to thank, on behalf of the National Committee, all those who contributed to United States participation in the Decade. It is impossible to do this adequately, because during the past ten years a large proportion of the water-related agencies, organizations, and institutions in this country took part in, furthered, and supported the projects and activities that made up the U.S. program for the International Hydrological Decade. Yet, if I may, I would like to single out the faithful and generous support of the National Science Foundation.
