WILSON'S  PROCLAMATION

    President Wilson has issued the following regarding the use of wireless telegraph stations:
    Whereas, Proclamations having been issued by me declaring the neutrality of the United States of America in the wars now existing between various European nations; and,
    Whereas, It is desirable to take precautions to insure the enforcement of said proclamations insofar as the use of radio communication is concerned;
    It is now ordered by virtue of authority vested in me to establish regulations on the subject; that all radio stations within the jurisdiction of the United States of America are hereby prohibited from transmitting or receiving for delivery messages of an unneutral nature, and from in any way rendering to any one of the belligerents any unneutral service during the continuance of hostilities.
    The enforcement of this order is hereby delegated to the secretary of the navy, who is authorized and directed to take such action in the premises as to him may appear necessary.
    This order to take effect from and after this date.
WOODROW  WILSON.        
The White House, August 5, 1914.    
    Secretary Daniels has instructed navy-yard commandants to detail officers to wireless stations in their vicinity as censors.
    These instructions for the officers charged with enforcing the president's order were issued by Secretary Daniels:
    No cipher or code messages are permitted to be transmitted to, or received from, radio ship or shore stations of belligerent nations by any government or commercial radio station situated in the United States or its possessions, or in territory under the jurisdiction of the United States, except cipher to or from United States officials.
    No cipher or code radio messages will be permitted to be sent from any radio stations in the United States via foreign stations if destined to a belligerent.
    Radio messages containing information relating to operations, material or personal, of armed forces of any belligerent nation will be considered as unneutral in character and will not be handled by radio stations under the jurisdiction of the United States.
    In general, the censoring official will assure himself beyond doubt that no message of an unneutral character is allowed to be handled
    In order to insure that the censors may in all cases be informed thoroughly and correctly as to the contents of radio messages coming under their censorship, they will demand, when necessary, that such messages be presented for their ruling in a language that is understandable to them.
    In case of doubt as to the character of a message, it should be stopped and its contents, with full explanation of details, be forwarded to the Department (Operation) by telegraph for instructions as to the proper procedure to follow.
JOSEPHUS  DANIELS,        
Secretary of the Navy.
