Our larger towns and cities still support gymnasia of greater or less size and perfectness. But the modern gymnasium has two great deficiencies: the lack of open air, and of the emulation arising from publicity. The first is a very grave objection. Not a tithe of the benefits of exercise can be obtained within-doors. The sallow mechanic and the ruddy farmer are the two points of comparison. The one may work as hard and be as strong as the other, and yet we cannot call him as healthy. Nothing short of Nature's own sweet air will supply the highest physical needs of the human frame. As our gymnasia are usually private, and only moderately frequented, the gymnast is not stimulated to those exertions which society and competition would arouse. _Ennui_ often mars his enjoyment. We have seen men methodically pursuing, day after day, the same exercises, with all the listless drudgery of a hack-horse. Geniality and generous emulation are among the great benefits of the true gymnasium. "But how shall I find time to follow out even one of these exercises?" objects the victim of American social life. It is true, he cannot. We live so fast that we have no time to live. Nevertheless, gymnastics have one advantage adapted to our hurried habits. They afford the most exercise in the shortest time. In no other way, so easily accessible, can as much powerful motion be used in so brief a space. The tired clerk or merchant comes home late, with feverish brain and weary legs. His chest and arms have had no exercise proportional to the rest of his system. What shall he do to restore the balance? If he can, let him erect in some upper room, away from furnace-heat, instead of a billiard-table, a private shrine to Apollo or Mercury. He will need but little apparatus. A set of weights and pulleys, a pair of parallel bars, two suspended rings, and a leaping-pole are all the necessary permanent fixtures. Other articles, as the dumb-bells, the Indian club, boxing-gloves, foils, or single-sticks, take up no room, and can be added as his growing taste for their use demands. We would single out the parallel bars and the weights as the most generally useful. The former develop particularly the chest, stretch the pectoral muscles, and lengthen the collar-bones. The latter increase the volume and power of the extensors of the shoulder, arm, and forearm, and are to be sedulously practised, because we have fewer common and daily movements of these muscles than of their antagonists, the flexors, and they are consequently weaker in most persons. The windows should be widely opened, and the room warmed by the sun alone.
