established and a set of regulations for the censorship of photographs was evolved. Among the pictures withheld from the public were those dealing with new inventions of military significance, such as radio telephony; with all examples of military and naval camouflage, and with the various new types of artillery, especially those on tractor mounts. Such photographs as were not released were placed in the archives of the War College to become a permanent part of the pictorial history of the war, while those which were passed were turned over to the Committee on Public Information for distribution to the various agencies which were in a position to give them the greatest publicity. There was also an informal, intimate, and extremely valuable service which the section was able to perform. As pictures were received from the A. E. F., a systematic effort was made to furnish to the relatives and friends of soldiers serving overseas copies of the photographs or sections of the films in which their loved ones appeared, of the hospitals in which they were being treated, or of the spots where they were buried. As a result of this official thoughtfulness, comfort was given to many a lonely wife, many an anxious parent. A no less important phase of the section’s activities was the censorship of still and motion pictures taken for commercial use at home and abroad and the supervision of the firms and individuals taking them. When one remembers that “The Birth of a Nation” is estimated to have been seen by 60,000,000 people, a realization can be had of the enormous possibilities of the motion-picture for purposes of propaganda and the necessity of subjecting it to rigid censorship. Whenever a picture contained a suggestion of enemy propaganda, or when the policy of a producing company appeared to be antagonistic to the interests of the United States, a systematic investigation was started to determine the loyalty of the officers of the organization and the source of its financial backing. If the enemy propaganda was evidently intentional, steps were immediately taken to prosecute the producers under the Espionage Act. If, however, as was usually the case, the fault was due to mere ignorance or thoughtlessness, a conference with the persons concerned generally resulted in the alteration or withdrawal of the offending picture.
