As the months go by, and it is found that the weaker ones have noticeably improved, and all are now capable of creditable performances at these various exercises, they may be carried safely on to the gymnasium--that is, if the school is fortunate enough to possess one. It is but a partially equipped school which is not provided with a good-sized, well-ventilated room, say of forty or fifty feet square (and one fifty by a hundred would do far better), fitted up with the simpler gymnastic appliances. Now the teacher, if up to his work, can render even more valuable assistance than before, by standing by the pupil, as he or she attempts the simplest steps on the parallel bars, or the rings, or the high bars, the pulley-weights, or the horizontal bar; constant explanations are to be given how to advance, and setting the example, detecting defects and correcting them on the spot, and all the while being ready to catch the pupil and prevent him or her from falling. An instructor soon finds that the pupils progress as rapidly as they did in the lighter preparatory work, while now they are entering on a field which, if faithfully cultivated, though for only the same brief intervals daily, will later on insure a class of strong, healthy, shapely, and symmetrical boys or girls, strong of arm and fleet of foot, familiar with what they can do, and knowing what is not to be attempted. Much, indeed the greater part, of the good to be derived from the gymnasium would have come from steadily adhering to the exercises above pointed out, so that even with no gymnasium excellent progress can be had; but results come quicker in the gymnasium, and the place invites greater freedom of action. In ten minutes in the morning, for instance, thirty or forty boys or girls could, following one another promptly, "walk" (on their hands) through the parallel bars with the elbows unbent, the head of the line crossing at once to the high bars, and "walk" or advance through them, first holding the weight on one hand and then on the other, then turning to the horizontal bar and vaulting over it. If the rear of the line is not yet through the forward "walk" on the parallels, those at the head could take a swing on the rings. Next, they could "walk" backward through the parallels, then through the high bars; then vault again, swing again, and then try the parallels anew--this time "jumping" forward, or advancing both hands at once, the arms of course being held rigidly straight. Then turning to the high bars, they could jump or advance through them, springing forward with both hands at once, vault again, the bar having meanwhile been raised, and either try the rings again or rest a moment, and then jump backward through the high bars.
