The Presidential pretension, which is continued to the present time, is the more unnatural when it is considered that there are at least three different statutes in which Congress has shown its purpose to limit the employment of military officers in civil service. As long ago as July 5, 1838, it was positively provided that no Army officers should be separated from their regiments and corps “for employment on civil works of internal improvement, or be allowed to engage in the service of incorporated companies”; nor any line officer to be acting paymaster or disbursing agent for the Indian Department, “if such extra employment require that he be separated from his regiment or company, or otherwise interfere with the performance of the military duties proper.”[131] Obviously the will of Congress is here declared, that officers should not be allowed to leave their posts for any service which might _interfere with the performance of the military duties proper_. This language is explicit. Then came the Act of March 30, 1868, which provides that “any officer of the Army or Navy of the United States, who shall, after the passage of this Act, accept or hold any appointment in the diplomatic or consular service of the Government, shall be considered as having resigned his said office, and the place held by him in the military or naval service shall be deemed and taken to be vacant.”[132] To a considerate and circumspect President, who recognized the law in its spirit as well as its letter, this provision, especially when reinforced by the earlier statute, would have been a rule of action in analogous cases, and therefore an insurmountable obstacle to a pretension which takes Army officers from their proper duties and makes them Presidential secretaries. A later statute adds to the obstacle. By Act of Congress of July 15, 1870, it is provided:-- “That it shall not be lawful for any officer of the Army of the United States on the active list _to hold any civil office, whether by election or appointment_; and any such officer _accepting or exercising the functions of a civil office_ shall at once cease to be an officer of the Army, and his commission shall be vacated thereby.”[133]
