The preliminary report of the select committee of the United States Senate appointed to investigate the executive agencies of the government with a view to coordination, under authority of Senate Resolution 217, 74th Congress, passed February 24, 1936, was presented to the Senate by Senator Harry F. Byrd, chairman, on August 16, 1937. Except for a brief introduction by Senator Byrd, in which he states that his committee has reached no final conclusions and that it expects to continue its investigations, the document is given over entirely to the report prepared for the committee by the Brookings Institution. Dr. Moulton, president of the Institution, explains in a letter of transmittal the contractual arrangements under which the report was prepared and lists the staff members, regular and special, who participated in its preparation.
