"Preach not me your musty Rules Ye Drones, that mould in idle cell; The Heart is wiser than the Schools, The Senses always reason well." COMUS. Our Philosophical Poet here gives the best practical maxim on the subject for Valetudinarians--who, by following his advice, may render their Existence, instead of a dull unvaried round of joyless, useless self-denial,--a circle of agreeable sensation;--for instance, go not to your Bed till You are tired of sitting up--then remain in an Horizontal posture,--till You long to change it for a Vertical: thus, by a little management, the inevitable business of Life may be converted into a source of continual Enjoyment. All-healing Sleep soon neutralizes the corroding caustic of Care--and blunts even the barbed arrows of the marble-hearted Fiend, Ingratitude. When the Pulse is almost paralysed by Anxiety,--half an hour's repose, will cheer the circulation, restore tranquillity to the perturbed spirit--and dissipate those heavy clouds of _Ennui_, which sometimes threaten to eclipse the brightest Minds, and best Hearts.--Child of Woe, lay thy Head on thy pillow, (instead of thy Mouth to the bottle,) and bless me for directing Thee to the true source of Lethe--and most sovereign _Nepenthé_ for the Sorrows of Human Life. The Time requisite to restore the waste occasioned by the action of the Day--depends on the activity of the habits, and on the Health of the Individual,--in general it cannot be less than Seven--and need not be more than Nine hours[28]. Invalids will derive much benefit from indulging in the _Siesta_ whenever they feel languid. A Sailor will tell you, that a Seaman can sleep as much in five hours, as a Landsman can in ten. Whether rising very early lengthens Life we know not,--but think that sitting up very late shortens it,--and recommend you to rise by eight, and retire to rest by eleven; your feelings will bear out the adage, that "_one_ Hour's rest before midnight, is worth _two_ after." When OLD PEOPLE have been examined with a view to ascertain the causes of their Longevity, they have uniformly agreed in one thing only,--that they ALL _went to Bed early, and rose early_. "Early to bed, and early to rise, Will make you healthy, wealthy, and wise." Dr. FRANKLIN published an ingenious Essay on the advantage of early rising--He called it "_an Economical Project_," and calculated, that the saving that might be made in the City of Paris, _by using Sunshine instead of Candles_--at no less than £4,000,000 Sterling.
