Finally, military ideals and methods of psycho-physical education are helpful regulations of the appetite for combat, and on the whole more wholesome and robust than those which are merely esthetic. Marching in step gives proper and uniform movement of legs, arms, and carriage of body; the manual of arms, with evolution and involution of figures in the ranks, gives each a corporate feeling of membership, and involves care of personal appearance and accouterments, while the uniform levels social distinction in dress. For the French and Italian and especially the German and Russian adolescent of the lower classes, the two or three years of compulsory military service is often compared to an academic course, and the army is called, not without some justification, the poor man's university. It gives severe drill, strict discipline, good and regular hours, plain but wholesome fare and out-of-door exercise, exposure, travel, habits of neatness, many useful knacks and devices, tournaments and mimic or play battles; these, apart from its other functions, make this system a great promoter of national health and intelligence. Naval schools for midshipmen, who serve before the mast, schools on board ship that visit a wide curriculum of ports each year, cavalry schools, where each boy is given a horse to care for, study and train, artillery courses and even an army drill-master in an academy, or uniform, and a few exterior features of soldierly life, all give a distinct character to the spirit of any institution. The very fancy of being in any sense a soldier opens up a new range of interests too seldom utilized; and tactics, army life and service, military history, battles, patriotism, the flag, and duties to country, should always erect a new standard of honor. Youth should embrace every opportunity that offers in this line, and instruction should greatly increase the intellectual opportunities created by every interest in warfare. It would be easy to create pregnant courses on how soldiers down the course of history have lived, thought, felt, fought, and died, how great battles were won and what causes triumphed in them, and to generalize many of the best things taught in detail in the best schools of war in different grades and lands.
