Prudence does not go behind nature and ask whence it is. It takes the laws of the world whereby man's being is conditioned, as they are, and keeps these laws that it may enjoy their proper good. It respects space and time, climate, want, sleep, the law of polarity, growth and death. There revolve, to give bound and period to his being on all sides, the sun and moon, the great formalists in the sky: here lies stubborn matter, and will not swerve from its chemical routine. Here is a planted globe, pierced and belted with natural laws and fenced and distributed externally with civil partitions and properties which impose new restraints on the young inhabitant.

We eat of the bread which grows in the field. We live by the air which blows around us and we are poisoned by the air that is too cold or too hot, too dry or too wet. Time, which shows so vacant, indivisible and divine in its coming, is slit and peddled into trifles and tatters. A door is to be painted, a lock to be repaired. I want wood or oil, or meal or salt; the house smokes, or I have a headache; then the tax, and an affair to be transacted with a man without heart or brains, and the stinging recollection of an injurious or very awkward word,--these eat up the hours. Do what we can, summer will have its flies; if we walk in the woods we must feed mosquitos; if we go a-fishing we must expect a wet coat. Then climate is a great impediment to idle persons; we often resolve to give up the care of the weather, but still we regard the clouds and the rain.

We are instructed by these petty experiences which usurp the hours and years. The hard soil and four months of snow make the inhabitant of the northern temperate zone wiser and abler than his fellow who enjoys the fixed smile of the tropics. The islander may ramble all day at will. At night he may sleep on a mat under the moon, and wherever a wild date-tree grows, nature has, without a prayer even, spread a table for his morning meal. The northerner is perforce a householder. He must brew, bake, salt and preserve his food, and pile wood and coal. But as it happens that not one stroke can labor lay to without some new acquaintance with nature, and as nature is inexhaustibly significant, the inhabitants of these climates have always excelled the southerner in force. Such is the value of these matters that a man who knows other things can never know too much of these. Let him have accurate perceptions. Let him, if he have hands, handle; if eyes, measure and discriminate; let him accept and hive every fact of chemistry, natural history and economics; the more he has, the less is he willing to spare any one. Time is always bringing the occasions that disclose their value. Some wisdom comes out of every natural and innocent action. The domestic man, who loves no music so well as his kitchen clock and the airs which the logs sing to him as they burn on the hearth, has solaces which others never dream of. The application of means to ends insures victory and the songs of victory not less in a farm or a shop than in the tactics of party or of war. The good husband finds method as efficient in the packing of fire-wood in a shed or in the harvesting of fruits in the cellar, as in Peninsular campaigns or the files of the Department of State. In the rainy day he builds a work-bench, or gets his tool-box set in the corner of the barn-chamber, and stored with nails, gimlet, pincers, screwdriver and chisel. Herein he tastes an old joy of youth and childhood, the cat-like love of garrets, presses and corn-chambers, and of the conveniences of long housekeeping. His garden or his poultry-yard tells him many pleasant anecdotes. One might find argument for optimism in the abundant flow of this saccharine element of pleasure in every suburb and extremity of the good world. Let a man keep the law,--any law,--and his way will be strown with satisfactions. There is more difference in the quality of our pleasures than in the amount.

On the other hand, nature punishes any neglect of prudence. If you think the senses final, obey their law. If you believe in the soul, do not clutch at sensual sweetness before it is ripe on the slow tree of cause and effect. It is vinegar to the eyes to deal with men of loose and imperfect perception. Dr. Johnson is reported to have said, --"If the child says he looked out of this window, when he looked out of that,--whip him." Our American character is marked by a more than average delight in accurate perception, which is shown by the currency of the byword, "No mistake." But the discomfort of unpunctuality, of confusion of thought about facts, of inattention to the wants of to-morrow, is of no nation. The beautiful laws of time and space, once dislocated by our inaptitude, are holes and dens. If the hive be disturbed by rash and stupid hands, instead of honey it will yield us bees. Our words and actions to be fair must be timely. A gay and pleasant sound is the whetting of the scythe in the mornings of June, yet what is more lonesome and sad than the sound of a whetstone or mower's rifle when it is too late in the season to make hay? Scatter-brained and "afternoon" men spoil much more than their own affair in spoiling the temper of those who deal with them. I have seen a criticism on some paintings, of which I am reminded when I see the shiftless and unhappy men who are not true to their senses. The last Grand Duke of Weimar, a man of superior understanding, said,--"I have sometimes remarked in the presence of great works of art, and just now especially in Dresden, how much a certain property contributes to the effect which gives life to the figures, and to the life an irresistible truth. This property is the hitting, in all the figures we draw, the right centre of gravity. I mean the placing the figures firm upon their feet, making the hands grasp, and fastening the eyes on the spot where they should look. Even lifeless figures, as vessels and stools--let them be drawn ever so correctly-- lose all effect so soon as they lack the resting upon their centre of gravity, and have a certain swimming and oscillating appearance. The Raphael in the Dresden gallery (the only greatly affecting picture which I have seen) is the quietest and most passionless piece you can imagine; a couple of saints who worship the Virgin and Child. Nevertheless, it awakens a deeper impression than the contortions of ten crucified martyrs. For beside all the resistless beauty of form, it possesses in the highest degree the property of the perpendicularity of all the figures." This perpendicularity we demand of all the figures in this picture of life. Let them stand on their feet, and not float and swing. Let us know where to find them. Let them discriminate between what they remember and what they dreamed, call a spade a spade, give us facts, and honor their own senses with trust.
