=Out-Door Exercises.=--Being free to enjoy the many out-door exercises, she should spend much time in the open air, making such choice of games and recreations as will bring into play the largest number of muscles, and afford the best all-round development, having in view, not only the securing of health and strength, but also the acquisition of grace and beauty. =Gymnasiums.=--If a capable instructor and a gymnasium are at hand, she should avail herself of both. Supplementing her out-door sports with these, she will, in a year’s time, unless already afflicted with some organic ailment or serious constitutional weakness, be so healthy, strong, and well developed, as to give promise of a long life, free from the infirmities that so commonly affect the sex. =Occupations of Men.=--The vital statistics, preserved by many progressive states and communities, afford opportunity for fruitful study and comparison. Of all occupations, that of the farmer or gardener conduces most to health and long life. His independent manner of living, the pure country air he breathes, the abundant sunshine he enjoys, the plain, wholesome food he eats, his restful, quiet sleep, and his freedom from the demands of fashionable life, all combine to give him health. But this occupation, in itself, probably brings into play a larger number of muscles than any other single employment. We cannot all be farmers, but whatever our occupation, there is much we can do to promote health, and to secure that happiness which is so largely dependent thereon. Many occupations afford exercise to a limited number of muscles, and those engaged therein should strive to find their recreation in the exercise of other muscles, so as to promote a well-rounded development. Persons who labor in-doors, and especially those who are confined to close workshops, stores, and schoolrooms, should have out-door recreation, with pure air and sunshine. =Unbalanced Bodies.=--Many lines of mechanical trade afford sufficient exercise to keep the workman in fairly good health, yet few, if any, give a symmetrical physical development. The blacksmith and stone mason usually have strong right hands and arms, while the left are less fully developed. Nine-tenths of all machinists are right-handed. In nearly all mechanical industries, the right arm and the back have the larger share of the work, while the chest and leg muscles and the left arm are neglected. =Indifference.=--Some workmen are so indifferent to physical symmetry that they are not willing to do anything to avert the one-sidedness resulting from their daily toil, even when convinced that a slight effort would correct the fault. The argument of increased health and vigor, and prolonged life, scarcely appeals to them.
