Linnæus was past sixty-two years old when he built a museum at his country-seat, where he classified and arranged a great number of plants, zoöphytes, shells, insects, and minerals. Besides this, he superintended the Royal Gardens, zealously pursued his scientific researches, corresponded by letter with many learned men, taught pupils, and lectured constantly in the Academic Gardens. His pupils travelled to all parts of the world, and sent him new plants and minerals to examine and classify. In the midst of this constant occupation, he wrote: “I tell the truth when I say that I am happier than the King of Persia. My pupils send me treasures from the East and the West; treasures more precious to me than Babylonish garments or Chinese vases. Here in the Academic Gardens is my Elysium. Here I learn and teach; here I admire, and point out to others, the wisdom of the Great Artificer, manifested in the structure of His wondrous works.” It is said that even when he was quite ill, the arrival of an unknown plant would infuse new life into him. He continued to labor with unremitting diligence till he was sixty-seven years old, when a fit of apoplexy attacked him in the midst of a public lecture, and so far impaired his memory that he became unable to teach.
The celebrated Alexander von Humboldt lived ninety years, and continued to pursue his scientific researches and to publish learned books up to the very year of his departure from this world.
The Rev. John Wesley continued to preach and write till his body was fairly worn out. Southey, his biographer, says: “When you met him in the street of a crowded city, he attracted notice, not only by his band and cassock, and his long hair, white and bright as silver, but by his pace and manner, both indicating that all his minutes were numbered, and that not one was to be lost.” Wesley himself wrote: “Though I am always in haste, I am never in a hurry; because I never undertake more work than I can go through with perfect calmness of spirit.” Upon completing his eighty-second year, he wrote: “It is now eleven years since I have felt any such thing as weariness. Many times I speak till my voice fails me, and I can speak no longer. Frequently I walk till my strength fails, and I can walk no farther. Yet even then I feel no sensation of weariness, but am perfectly easy from head to foot. I dare not impute this to natural causes. It is the will of God.” A year later, he wrote: “I am a wonder to myself. Such is the goodness of God, that I am never tired, either with writing, preaching, or travelling.”
Isaac T. Hopper, who lived to be past eighty, was actively employed in helping fugitive slaves, and travelling about to exercise a kindly and beneficent influence in prisons, until a very short time before his death. When he was compelled to take to his bed, he said to me: “I am ready and willing to go, only there is so much that I want to do.”
Some will say it is not in their power to do such things as these men did. That may be. But there is something that everybody can do. Those whose early habits render it difficult, or impossible, to learn a new science, or a new language, in the afternoon of life, can at least oil the hinges of memory by learning hymns, chapters, ballads, and stories, wherewith to console and amuse themselves and others. A stock of nursery rhymes to amuse little children is far from being a foolish or worthless acquisition, since it enables one to impart delight to the little souls,
“With their wonder so intense,
And their small experience.”
Women undoubtedly have the advantage of men, in those in-door occupations best suited to the infirm; for there is no end to the shoes that may be knit for the babies of relatives, the tidies that may be crocheted for the parlors of friends, and the socks that may be knit for the poor. But men also can find employment for tedious hours, when the period of youthful activity has passed. In summer, gardening is a never-failing resource both to men and women; and genial qualities of character are developed by imparting to others the flowers, fruit, and vegetables we have had the pleasure of raising. The Rev. Dr. Prince of Salem was always busy, in his old age, making telescopes, kaleidoscopes, and a variety of toys for scientific illustrations, with which he instructed and entertained the young people who visited him. My old father amused himself, and benefited others, by making bird-houses for children, and clothes-horses and towel-stands for all the girls of his acquaintance who were going to housekeeping. I knew an old blind man, who passed his winter evenings pleasantly weaving mats from corn-husks, while another old man read to him. A lathe is a valuable resource for elderly people; and this employment for mind and hands may also exercise the moral qualities, as it admits of affording pleasure to family and friends by innumerable neatly-turned little articles. The value of occupation is threefold to elderly people, if usefulness is combined with exercise; for in that way the machinery of body, mind, and heart may all be kept from rusting.
A sister of the celebrated John Wilkes, a wise and kindly old lady, who resided in Boston a very long time ago, was accustomed to say, “The true secret of happiness is always to have a little less time than one wants, and a little more money than one needs.” There is much wisdom in the saying, but I think it might be improved by adding, that the money should be of one’s own earning.
After life has passed its maturity, great care should be taken not to become indifferent to the affairs of the world. It is salutary, both for mind and heart, to take an interest in some of the great questions of the age; whether it be slavery or war, or intemperance, or the elevation of women, or righting the wrongs of the Indians, or the progress of education, or the regulation of prisons, or improvements in architecture, or investigation into the natural sciences, from which proceed results so important to the daily comfort and occupations of mankind. It is for each one to choose his object of especial interest; but it should be remembered that no person has a right to be entirely indifferent concerning questions involving great moral principles. Care should be taken that the daily social influence which every man and woman exerts, more or less, should be employed in the right direction. A conscientious man feels himself in some degree responsible for the evil he does not seek to prevent. In the Rev. John Wesley’s journal for self-examination this suggestive question occurs: “Have I embraced every probable opportunity of doing good, and of preventing, removing, or lessening evil?” Such habits of mind tend greatly to the improvement of our own characters, while at the same time they may help to improve the character and condition of others. Nothing is more healthy for the soul than to go out of ourselves, and stay out of ourselves. We thus avoid brooding over our own bodily pains, our mental deficiencies, or past moral shortcomings; we forget to notice whether others neglect us, or not; whether they duly appreciate us, or not; whether their advantages are superior to ours, or not. He who leads a true, active, and useful life has no time for such corrosive thoughts. All self-consciousness indicates disease. We never think about our stomachs till we have dyspepsia. The moral diseases which induce self-consciousness are worse than the physical, both in their origin and their results. To indulge in repinings over our own deficiencies, compared with others, while it indicates the baneful presence of envy, prevents our making the best use of such endowments as we have. If we are conscious of our merits, bodily or mental, it takes away half their value. There is selfishness even in anxiety whether we shall go to heaven or not, or whether our souls are immortal or not. A continual preparation for eternal progress is the wisest and the happiest way to live here. If we daily strive to make ourselves fit companions for angels, we shall be in constant readiness for a better world, while we make sure of enjoying some degree of heaven upon this earth; and, what is still better, of helping to make it a paradise for others.
