The great majority of the people, like galley slaves chained to their oars, must remain in the same place throughout the year, others may have a vacation of several weeks, and still others are free to change their location as often as fancy calls them. The latter might well learn from the birds, and by migrating with the temperature, going far north in summer and far south in winter, maintain themselves throughout the entire year in the most perfect atmospheric conditions for health, happiness, and long life. Many a man of fifty, having accumulated enough to modestly supply his wants, could add ten to thirty years to his life, or might even double the period of his existence, by ceasing to strive after riches, and by giving himself up to a healthful movement about this beautiful world. His principal companions should be good books,—the study of which will enlarge his mental horizon and increase his capacity to see, comprehend, and enjoy, and fit him to speak, act, and think in ways that will inure to the public good. If he has not had the benefits of a college education, now is the golden opportunity to read, and have pleasure in the reading, popular books on Geology, Botany, Biology, Astronomy, and Physics, and to become familiar with the history of his own country and of the world. It need not be a period of idleness but one of beautiful growth and of appreciation of the wonders of creation. And thus will his spirit be lifted up and fitted for a higher realm of existence in the world to come. To those who must remain at home during heat spells, the advice is given to close not only the shutters but the windows on the east side of the house during the forenoon and do the same on the west side in the afternoon. The best night’s sleep will be gained in a room facing north on any floor that is not next the roof; this room will be cooler if it is protected by another room on its east and one on its west side.
