This Committee, whose members have been W. S. Adams, J. A. Fleming, and F. E. Wright since formation by the President of the Carnegie Institution of Washington in December, 1932, to coordinate research on cosmic rays supported by the Institution, has submitted its fourteenth and final annual report for the year ended June 30, 1946. With the retirement from active service in the Institution on or before June 30, 1946, of its three members, the Committee recommended to President Bush that, effective July 1, 1946, (1) administration of its then uncompleted activities be made the responsibility of the Department of Terrestrial Magnetism of the Institution, and (2) funds still available from past appropriations be set aside, in accordance with the approved projects listed below, for disbursement by that Department through its Director. The President approved these recommendations and future reports on the completion of projects sponsored by the Committee will be made in the annual reports of the Director of the Department of Terrestrial Magnetism.As has been indicated in the annual reports of the Committee from 1940, relatively large progress could not be made during the war years. In view of the fundamental importance of this branch of physics, this limited progress, as one would expect, has raised more questions than answers. With the cessation of hostilities and the eventual reconversion from wartime to peacetime efforts of the investigators in the field of cosmic radiation, it may well be expected that research will be vigorously resumed, particularly in the investigation of high‐energy radiations to which natural cosmic radiation gives an immediate avenue of approach. Thereby we may expect to learn basic facts by which to check theories of nuclear forces and interactions between radiation and matter.
