Among the treasons incident to the Rebellion, none struck loyal minds more painfully than the desertion of the national right by Southern cadets and graduates of West Point. Some supposed that the diligent inculcation of State-Sovereignty doctrine by every organ of Southern opinion could not alone have caused this breach of plighted faith, and it was charged against the education given at the Academy, that it was based on "principles which permitted no discrimination between acts morally wrong in themselves, and acts which, destitute of immorality, are, nevertheless, criminal, because prohibited by the regulations of the institution." The charge indicated a gross misconception of the subject. The conduct-roll, which is to determine the standing of the cadet according to a total of demerit-marks, must include in one list delinquencies against all rules, whatever may be their source. But besides this scale for classification, the military law, to which cadets, as part of the army, are amenable, refers all immoralities and criminalities to a military tribunal. It would be well, if our collegians would try to estimate the effect, moral, intellectual, and physical, of the training of the Academy, as contrasted with that which they are receiving, and, in comparing a collegiate with a West-Point graduation, to remember that the cadet has been on service, and would have been discharged by his paymaster, if he had not done his duty, while in the colleges the professors serve for the pay, and would lose their bread and butter, if there were no degrees given. _Roundabout Papers_.
