Millions of our people pass their lives in cities and towns, and at work which keeps them nearly all day in-doors. Many hours are devoted for days and years, under careful teachers, and many millions of dollars are spent annually, in educating the mind and the moral nature. But the body is allowed to grow up all uneducated; indeed, often such a weak, shaky affair that it gets easily out of order, especially in middle and later life, and its owner is wholly unequal to tasks which would have proved easy to him, had he given it even a tithe of the education bestowed so generously in other directions. Not a few, to be sure, have the advantage in youth of years of active out-door life on a farm, and so lay up a store of vigor which stands them in good stead throughout a lifetime. But many, and especially those born and reared in towns and cities, have had no such training, or any equivalent, and so never have the developed lungs and muscles, the strong heart and vigorous digestion—in short, the improved tone and strength in all their vital organs—which any sensible plan of body-culture, followed up daily, would have secured. It does not matter so much whether we get vigor on the farm, the deck, the tow-path, or in the gymnasium, if we only get it. Fortunately, if not gotten in youth, when we are plastic and easily shaped, it may still be had, even far on in middle life, by judicious and systematic exercise, aimed first to bring up the weak and unused parts, and then by general work daily which shall maintain the equal development of the whole.

The aim here has been, not to write a profound treatise on gymnastics, and point out how to eventually reach great performance in this art, but rather in a way so plain and untechnical that even any intelligent boy or girl can readily understand it, to first give the reader a nudge to take better care of his body, and so of his health, and then to point out one way to do it. That there are a hundred other ways is cheerfully conceded. If anything said here should stir up some to vigorously take hold of, and faithfully follow up, either the plan here indicated or any one of these others, it cannot fail to bring them marked benefit, and so to gratify
