The annual course at the academy is divided into two distinct periods, the first extending from June till September, and the second from September to the following June. During the first period, the cadets leave their barracks and encamp in tents, and are made subject to the police and discipline of an army in time of war. In addition to the thorough and severe course of practical exercises and drills in the different arms during these three summer months of each year, they are made to perform the same tours of guard-duty, night and day, as is required of the common soldier in time of actual war. This continues till the first of September of each year, when the cadets return to their barracks, and for the remaining nine months devote themselves to the prescribed course of scientific and military studies, intermixed with military exercises and practical operations in the laboratory and on the field. To test the progress of the cadets in their studies, there are held semi-annual public examinations. These examinations are strict and severe, and all who fail to come up to the fixed standard are obliged to withdraw from the institution, to allow some one else from the same district to make the trial. During their course of studies the cadets, as warrant-officers of the army, draw pay barely sufficient to defray their necessary expenses. The allowance to each is twenty-six dollars per month, but none of this is paid to the cadet, but is applied to the purchase of books, fuel, lights, clothing, board, &c. This institution furnishes each year to the army about forty subaltern officers, thoroughly instructed in all the theoretical and practical duties of their profession. After completing this course, the cadet is usually promoted from the grade of warrant-officer to that of a commissioned officer, and is immediately put on duty with his regiment or corps. This system of appointment to the army has produced the most satisfactory results, and has received the commendation of our best military men, and the approbation of all our presidents and most able statesmen. Nevertheless, it has occasionally met with strong opposition; this opposition springing in part from a want of proper information respecting the character and working of the system, and in part from the combined efforts of those who from negligence or incapacity have failed to pass their examinations for promotion, and of those who, from a conscious want of qualifications or merit, feel assured that they cannot obtain commissions in the army so long as this system of merit, as fixed by examination, shall exist. Hence the effort to destroy the Military Academy and to throw the army entirely open to _political_ appointment.
