At Harvard, for instance, to-day there is in process of erection, at great expense, a gymnasium which, when finished, will doubtless be the most costly building of the sort in this country, and very possibly the best appointed as well. But unless there is introduced some sensible and vigorous system of bringing the students regularly there, and working them while they are there, it will almost surely prove a failure, and accomplish little or no more good than did the old one. Now, suppose, first that this new institution is to be carried on with no more vigor or good sense than its predecessors. Next, suppose that, opposite this expensive affair, on some neighboring field, there were built a commodious shed, costing perhaps one-tenth as much as its more pretentious rival, strongly framed, weather-tight, sensibly arranged, well lit, and comfortably warmed, large enough, too, to admit, at the edge of the main room, of a running track of say twenty laps to the mile. In an L adjoining let there be ample and well-ventilated dressing-rooms, a locker for each student, and sufficient washing facilities to meet the demand. Suppose the ordinary sorts of apparatus were there, but made with great care, and of the proportions skilled gymnasts have found most suitable. Let there be, besides, all newly-invented appliances which have proved valuable, such as the twenty or more Dr. Sargent has introduced, and any other good ones as well. Suppose, too, that heavy weights for lifting, and all heavy clubs and dumb-bells, were carefully excluded. On the walls there should be casts and drawings, showing well-proportioned and well-developed arms, legs, and trunks, and a brief statement with each of the various measurements and proportions, and the ages of the men from whom they were taken, and, if possible, the sort and amount of work done by each in their progress. These need by no means be all modern. Greece and Rome, Troy and Pompeii, could furnish their quota. Suppose the director at once, on the joining of a pupil, recorded, on a page set apart specially in his register, the age, height, general physical characteristics, weight, girth of calf, thigh, hips, waist, lower chest, upper chest--both at rest and inflated--neck, upper arm--extended and drawn up--and the forearm, hand, and wrist, taking care to note the time of day the measurements were made, and also obtaining a photograph of the man as he then appeared in exercising costume. Suppose that, outside of the ordinary requirements as to method, decorum, order of using apparatus, and so on, the director refused to take any pupil who would not expressly agree to two things: first, to be at the gymnasium, stripped and ready for work, exactly at such a moment, four days out of the seven; second, to obey implicitly the director's orders, both as to what work he should do, and what omit.
