When any member of this senior division has completed two academic years of service in that division; has been selected by the president of the institution and by its professor of military science and tactics (who must be an army officer); has made a written agreement to continue in the Reserve Officers' Training Corps for the remainder of his course in the institution, devoting five hours per week to the military training prescribed by the Secretary of War; has also made a written agreement to pursue the courses in training camps (one camp of not more than six weeks' duration each year) prescribed by the Secretary of War)--when he has fulfilled all these conditions, he may be given, at the expense of the United States, a money commutation of subsistence at a rate not exceeding the cost of the garrison (army) ration during the remainder of his service in the Reserve Officers' Training Corps. This will amount to about thirty cents a day. This provision applies only to the senior division. JUNIOR DIVISION A junior division of the Reserve Officers' Training Corps may be established at any institution to which an army officer has been detailed as the professor of military science and tactics, and which cannot meet the necessary requirements for the senior division. In this case the Government does not give a commutation of subsistence and the students are not asked to obligate themselves as in the senior division. TO ENTER THE RESERVE OFFICERS' CORPS The President is authorized, under such regulations as he may prescribe, to appoint in the Officers' Reserve Corps any graduate of the senior division of the Reserve Officers' Training Corps, who shall have satisfactorily completed the two-year course of training (five hours a week), incident to receiving a commutation of rations; also any graduate of the junior division who shall have satisfactorily completed the courses of military training prescribed for students of the senior divisions, referred to in the first part of this paragraph, and shall have participated in such practical instruction, subsequent to graduation, as the Secretary of War shall have prescribed. They must be twenty-one years of age and must make written agreement under oath to serve the United States for ten years. Any physically fit male citizen of the United States, between the ages of twenty-one and twenty-seven years, who graduated prior to June 22, 1916, from any educational institution at which an officer of the Army was detailed as professor of military science and tactics, and who, while a student at such institution, completed courses of military training substantially equivalent to those prescribed for the senior division of the Reserve Officers' Training Corps, may, after satisfactorily completing such additional practical military training as the Secretary of War shall prescribe, be eligible for appointment to the Officers' Reserve Corps.
