The President of the United States of America, authorized by Act of Congress, July 9, 1918, takes pleasure in presenting the Army Distinguished Service Medal to Major (Judge Advocate General) Joshua Reuben Clark, Jr., United States Army, for exceptionally meritorious and distinguished services to the Government of the United States, in a duty of great responsibility during World War I. As Special Assistant to the Attorney General of the United States from June 1917 until September 1918, by his zeal, great industry, and eminent legal attainments, Major Clark rendered conspicuous services in the compilation and publication of an extremely valuable and comprehensive edition of the laws and analogue legislation pertaining to the war powers of our Government since its beginning. From September to December 1918, as Executive Officer of the Provost Marshal General’s Office, he again rendered services of inestimable value in connection with the preparation and execution of complete regulations governing this classification and later the demobilization of several million registrants.
