“The Division of Military Aeronautics will have control of the training of aviators and military use of aircraft. The exact division of functions in the matter of designing and engineering will be worked out as experience determines between the Division of Military Aeronautics and the Division of Production. “This announcement involves no change of personnel in the present Equipment Division of the Signal Corps, of which W. C. Potter is chief, and which will continue under his direction.” This reorganization, however, was admittedly but the first step. The first action taken by the President under the broad powers of the Overman Act was to effect a still further reorganization by taking aviation entirely out of the jurisdiction of the Signal Corps, where it has been from its inception on July 18, 1914, and to set up two separate bureaus, one for securing and training the large flying and ground forces, and the other for providing planes, engines, and equipment. The presidential order of May 21 covering this change follows: “By virtue of the authority in me vested as Commander-in-Chief of the Army and by virtue of further authority upon me specifically conferred by ‘An act authorizing the President to coordinate or consolidate executive bureaus, agencies, and offices, and for other purposes, in the interest of economy and the more efficient concentration of the Government,’ approved May 20, 1918, I do hereby make and publish the following order: “The powers heretofore conferred by law or by Executive order upon and the duties and functions heretofore performed by the Chief Signal Officer of the Army are hereby redistributed as follows: I “(1) The Chief Signal Officer of the Army shall have charge, under the direction of the Secretary of War, of all military signal duties, and of books, papers and devices connected therewith, including telegraph and telephone apparatus and the necessary meteorological instruments for use on target ranges, and other military uses; the construction, repair, and operation of military telegraph lines, and the duty of collecting and transmitting information for the Army by telegraph or otherwise, and all other duties usually pertaining to military signaling; and shall perform such other duties as now or are or shall hereafter be devolved by law or by Executive order upon said Chief Signal Officer which are not connected with the Aviation Section of the Signal Corps or with the purchase, manufacture, maintenance, and production of aircraft, and which are not hereinafter conferred, in special or general terms, upon other officers or agencies.
