The Administrative Branch of the Military Intelligence Division, referred to, for the sake of convenience, as M I 1, co-ordinates the activities of the other eleven sections, six of which, M I 2, M I 5, M I 6, M I 7, M I 8, and M I 9, form the Positive Branch of the service, the Negative Branch consisting of M I 3, M I 4, M I 10, M I 11, and M I 13. The Second Section (M I 2) is divided in turn into five subsections, four of which—Combat, Political, Economic, and Psychologic—devote themselves to the collation of information, the maintenance of the “Current Estimate,” of which more hereafter, and the furnishing of special reports. Another subsection deals with the preparation of military monographs. M I 5 collects information for the use of the Positive Branch and supervises the military attachés. M I 6 concerns itself with the translation of documents for all branches of the War Department. M I 7 has charge of all maps and photographs, one of its subsections devoting itself to map construction and another having the custody of the War Department map collection. To M I 8 is intrusted the solution of codes and ciphers, the study of shorthand systems, encoding and decoding, the compilation of codes, and the maintenance of a laboratory for the detection of invisible inks. M I 9 has supervision of the training of intelligence officers and men for work in the field. Turning to the Negative Branch of the division, M I 3 is charged with counter-espionage within the military establishment, together with collateral activities directly affecting the army. The eleven subsections of M I 3 deal with such diverse subjects as the preparation of bulletins, summaries, and surveys; and of instructions for intelligence officers, counter-espionage in prison camps, disciplinary barracks, the District of Columbia, the various branches of the Staff and Line, and among conscientious objectors, and the investigation of applicants for commissions. M I 4 conducts counter-espionage outside the military service in the United States and abroad, with particular reference to sabotage and the protection of plants and means of communication, its activities covering nearly the entire world. M I 10 is charged with the censorship of letters, books, newspapers, and periodicals, telegraphs and telephones, and radiophotographs and motion-pictures, and with a general supervision of the foreign-language press. M I 11 passes on passport applications and, in co-operation with certain other bureaus, has charge of port control. M I 13 is the Graft and Fraud Section, its work being principally concerned with criminal activities which may affect the army. The present Morale Branch of the General Staff consists, as its name indicates, in maintaining the morale of the army, which includes the encouragement and supervision of soldier publications, military advertising, camp-posters, and the treatment of the foreign-speaking and negro soldier problems
