How to become a Cadet, is a question not unlikely to arise in the minds of some of the young readers of this volume. The martial aspirant should consider well, before taking any steps toward securing a Cadet appointment, that Cadet life is no mere holiday training--no refined dandyism, but a four years' devotion of mind, body, and heart to discipline and study; more severe, by far, than is required at any other educational institution in the land. But if possessed of an aptitude for mathematical study, of a vigorous realization of the attributes of manhood, and the courage to endure patiently present trials for future good, and finally, if possessed of an ardent desire for intellectual culture, with a view to after usefulness, nowhere can a youth become so well qualified by an educational course to be a man, as by becoming a Cadet at the National Military Academy. The method of procedure to secure an appointment is briefly as follows: The District of Columbia, and each District of Country entitled to a Member of the House of Representatives in Congress, may secure through him one Cadet appointment. The Cadet so selected should remain four years, but in case he fails to do so, a vacancy arises which the Representative is called upon to fill with a new appointee. Of course, the same thing occurs when the Cadet graduates, and thus the number of Cadets is made equal to the number of Representatives and Delegates in Congress. In addition, every year the President of the United States appoints TEN Cadets, selected at his pleasure from any portion of the country. The appointments by Districts are really made by the Secretary of War, but only on the recommendation of the Member of Congress. An application made to the latter will show whether a vacancy exists--if so, the applicant must plead with him for it. The only other alternative is to secure the favor of being one of the TEN appointed by the President. The official qualifications are herewith appended: APPOINTMENT AND ADMISSION OF CADETS. I.--As frequent inquiries are made in regard to the mode of procuring admission into the Military Academy, persons interested in the subject are hereby informed that application may be made at any time (by letter to the Secretary of War) by the applicant himself, his parent, guardian, or any of his friends, that his name may be placed on the register in the office of the Inspector at Washington. The precise age and permanent abode of the applicant, as, also, the number of the Congressional District in which he resides, must be stated, and no application will be considered wherein these instructions are not complied with. No preference is given to applications on account of priority, nor can any information be communicated as to the probable success of an applicant before the appointments are made.
