Chapter 68 : Advance, then, with caution, the balance in your hand. Put into one scale the pleasures

Advance, then, with caution, the balance in your hand. Put into one scale the pleasures which any object may offer; but put fairly into the other the pains which are to follow, and see which preponderates. The making an acquaintance is not a matter of indifference. When a new one is proposed to you, view it all round. Consider what advantages it presents, and to what inconveniences it may expose you. Do not bite at the bait of pleasure, till you know there is no hook beneath it. The art of life is the art of avoiding pain; and he is the best pilot, who steers clearest of the rocks and shoals with which it is beset. Pleasure is always before us; but misfortune is at our side: while running after that, this arrests us. The most effectual means of being secure against pain, is to retire within ourselves, and to suffice for our own happiness. Those which depend on ourselves, are the only pleasures a wise man will count on; for nothing is ours, which another may deprive us of. Hence the inestimable value of intellectual pleasures. Ever in our power, always leading us to something new, never cloying, we ride serene and sublime above the concerns of this mortal world, contemplating truth and nature, matter and motion, the laws which bind up their existence, and that Eternal Being, who made and bound them up by those laws. Let this be our employ. Leave the bustle and tumult of society to those who have not talents to occupy themselves without them.

Friends.h.i.+p is but another name for an alliance with the follies and the misfortunes of others. Our own share of miseries is sufficient: why enter then as volunteers into those of another? Is there so little gall poured into our cup, that we must heed help to drink that of our neighbor? A friend dies, or leaves us: we feel as if a limb was cut off.

He is sick: we must watch over him, and partic.i.p.ate of his pains. His fortune is s.h.i.+pwrecked: ours must be laid under contribution. He loses a child, a parent, or a partner: we must mourn the loss as if it were our own.

Heart. And what more sublime delight, than to mingle tears with one whom the hand of Heaven hath smitten! to watch over the bed of sickness, and to beguile its tedious and its painful moments! to share our bread with one to whom misfortune has left none! This world abounds indeed with misery: to lighten its burthen, we must divide it with one another. But let us now try the virtue of your mathematical balance, and as you have put into one scale the burthens of friends.h.i.+p, let me put its comforts into the other. When languis.h.i.+ng then under disease, how grateful is the solace of our friends! how are we penetrated with their a.s.siduities and attentions! how much are we supported by their encouragements and kind offices! When Heaven has taken from us some object of our love, how sweet is it to have a bosom whereon to recline our heads, and into which we may pour the torrent of our tears! Grief, with such a comfort, is almost a luxury! In a life where we are perpetually exposed to want and accident, yours is a wonderful proposition, to insulate ourselves, to retire from all aid, and to wrap ourselves in the mantle of self-sufficiency! For a.s.suredly n.o.body will care for him, who cares for n.o.body. But friends.h.i.+p is precious, not only in the shade, but in the suns.h.i.+ne of life: and thanks to a benevolent arrangement of things, the greater part of life is suns.h.i.+ne. I will recur for proof to the days we have lately pa.s.sed. On these, indeed, the sun shone brightly! How gay did the face of nature appear! Hills, valleys, chateaux, gardens, rivers, every object wore its liveliest hue! Whence did they borrow it?

From the presence of our charming companion. They were pleasing, because she seemed pleased. Alone, the scene would have been dull and insipid: the partic.i.p.ation of it with her gave it relish. Let the gloomy monk, sequestered from the world, seek unsocial pleasures in the bottom of his cell! Let the sublimated philosopher grasp visionary happiness, while pursuing phantoms dressed in the garb of truth! Their supreme wisdom is supreme folly: and they mistake for happiness the mere absence of pain.

Had they ever felt the solid pleasure of one generous spasm of the heart, they would exchange for it all the frigid speculations of their lives, which you have been vaunting in such elevated terms. Believe me, then, my friend, that that is a miserable arithmetic, which could estimate friends.h.i.+p at nothing, or at less than nothing. Respect for you has induced me to enter into this discussion, and to hear principles uttered, which I detest and abjure. Respect for myself now obliges me to recall you into the proper limits of your office. When nature a.s.signed us the same habitation, she gave us over it a divided empire. To you she allotted the field of science; to me that of morals.

When the circle is to be squared, or the orbit of a comet to be traced; when the arch of greatest strength, or the solid of least resistance is to be investigated, take up the problem; it is yours; nature has given me no cognizance of it. In like manner, in denying to you the feelings of sympathy, of benevolence, of grat.i.tude, of justice, of love, of friends.h.i.+p, she has excluded you from their control. To these she has adapted the mechanism of the heart. Morals were too essential to the happiness of man, to be risked on the uncertain combinations of the head. She laid their foundation, therefore, in sentiment, not in science. That she gave to all, as necessary to all: this to a few only, as sufficing with a few. I know indeed, that you pretend authority to the sovereign control of our conduct, in all its parts: and a respect for your grave saws and maxims, a desire to do what is right, has sometimes induced me to conform to your counsels. A few facts, however, which I can readily recall to your memory, will suffice to prove to you, that nature has not organized you for our moral direction. When the poor wearied soldier, whom we overtook at Chickahominy, with his pack on his back, begged us to let him get up behind our chariot, you began to calculate that the road was full of soldiers, and that if all should be taken up, our horses would fail in their journey. We drove on therefore.

But soon becoming sensible you had made me do wrong, that though we cannot relieve all the distressed, we should relieve as many as we can, I turned about to take up the soldier; but he had entered a by-path, and was no more to be found: and from that moment to this, I could never find him out to ask his forgiveness. Again, when the poor woman came to ask a charity in Philadelphia, you whispered, that she looked like a drunkard, and that half a dollar was enough to give her for the ale-house. Those who want the dispositions to give, easily find reasons why they ought not to give. When I sought her out afterwards, and did what I should have done at first, you know, that she employed the money immediately towards placing her child at school. If our country, when pressed with wrongs at the point of the bayonet, had been governed by its heads instead of its' hearts, where should we have been now? Hanging on a gallows as high as Hainan's. You began to calculate, and to compare wealth and numbers: we threw up a few pulsations of our blood; we supplied enthusiasm against wealth and numbers; we put our existence to the hazard, when the hazard seemed against us, and we saved our country: justifying, at the same time, the ways of Providence, whose precept is, to do always what is right, and leave the issue to him. In short, my friend, as far as my recollection serves me, I do not know that I ever did a good thing on your suggestion, or a dirty one without it. I do for ever, then, disclaim your interference in my province. Fill paper as you please with triangles and squares: try how many ways you can hang and combine them together. I shall never envy nor control your sublime delights. But leave me to decide when and where friends.h.i.+ps are to be contracted. You say I contract them at random. So you said the woman at Philadelphia was a drunkard. I receive none into my esteem, till I know they are worthy of it. Wealth, t.i.tle, office, are no recommendations to my friends.h.i.+p. On the contrary, great good qualities are requisite to make amends for their having wealth, t.i.tle, and office. You confess, that, in the present case, I could not have made a worthier choice.

You only object, that I was so soon to lose them. We are not immortal ourselves, my friend; how can we expect our enjoyments to be so? We have no rose without its thorn; no pleasure without alloy. It is the law of our existence; and we must acquiesce. It is the condition annexed to all our pleasures, not by us who receive, but by him who gives them. True, this condition is pressing cruelly on me at this moment. I feel more fit for death than life. But when I look back on the pleasures of which it is the consequence, I am conscious they were worth the price I am paying. Notwithstanding your endeavors, too, to damp my hopes, I comfort myself with expectations of their promised return. Hope is sweeter than despair; and they were too good to mean to deceive me. 'In the summer,'

said the gentleman; but 'In the spring,' said the lady; and I should love her for ever, were it only for that! Know, then, my friend, that I have taken these good people into my bosom; that I have lodged them in the warmest cell I could find; that I love them, and will continue to love them through life; that if fortune should dispose them on one side the globe, and me on the other, my affections shall pervade its whole ma.s.s to reach them. Knowing then my determination, attempt not to disturb it. If you can at any time furnish matter for their amus.e.m.e.nt, it will be the office of a good neighbor to do it. I will, in like manner, seize any occasion which may offer, to do the like good turn for you with Condorcet, Rittenhouse, Madison, La Cretelle, or any other of those worthy sons of science, whom you so justly prize.

I thought this a favorable proposition whereon to rest the issue of the dialogue. So I put an end to it by calling for my nightcap. Methinks, I hear you wish to Heaven I had called a little sooner, and so spared you the _ennui_ of such a sermon. I did not interrupt them sooner, because I was in a mood for hearing sermons. You, too, were the subject; and on such a thesis, I never think the theme long; not even if I am to write it, and that slowly and awkwardly, as now, with the left hand. But that you may not be discouraged from a correspondence, which begins so formidably, I will promise you, on my honor, that my future letters shall be of a reasonable length. I will even agree to express but half my esteem for you, for fear of cloying you with too full a dose. But on your part, no curtailing. If your letters are as long as the Bible, they will appear short to me. Only let them be brim full of affection. I shall read them with the dispositions with which Arlequin, in _Les Deux Billets_, spelt the words '_Je t'aime,_' and wished that the whole alphabet had entered into their composition.

We have had incessant rains since your departure. These make me fear for your health, as well as that you had an uncomfortable journey. The same cause has prevented me from being able to give you any account of your friends here. This voyage to Fontainebleau will probably send the Count de Moutier and the Marquis de Brehan to America. Danquerville promised to visit me, but has not done it as yet. De la Tude comes sometimes to take family soup with me, and entertains me with anecdotes of his five and thirty years' imprisonment. How fertile is the mind of man, which can make the Bastille and dungeon of Vincennes yield interesting anecdotes! You know this was for making four verses on Madame de Pompadour. But I think you told me you did not know the verses. They were these.

'Sans esprit, sans sentiment, Sans etre belle, ni neuve, En France on peut avoir le premier amant: Pompadour en est Tepreuve.'

I have read the memoir of his three escapes. As to myself, my health is good, except my wrist, which mends slowly, and my mind, which mends not at all, but broods constantly over your departure. The lateness of the season obliges me to decline my journey into the south of France.

Present me in the most friendly terms to Mr. Cosway, and receive me into your own recollection with a partiality and warmth, proportioned not to my own poor merit, but to the sentiments of sincere affection and esteem, with which I have the honor to be, my Dear Madam,

Your most obedient, humble servant,

Th: Jefferson.

LETTER XXIX.--TO MRS. COSWAY, October 13, 1786

TO MRS. COSWAY.

Paris, October 13, 1786.

My Dear Madam,

Just as I had sealed the enclosed, I received a letter of a good length, dated Antwerp, with your name at the bottom. I prepared myself for a feast. I read two or three sentences: looked again at the signature, to see if I had not mistaken it. It was visibly yours. Read a sentence or two more. Diable! Spelt your name distinctly. There was not a letter of it omitted. Began to read again. In fine, after reading a little, and examining the signature alternately, half a dozen times, I found that your name was to four lines only, instead of four pages. I thank you for the four lines, however, because they prove you think of me; little, indeed, but better little than none. To show how much I think of you, I send you the enclosed letter of three sheets of paper, being a history of the evening I parted with you. But how expect you should read a letter of three mortal sheets of paper? I will tell you. Divide it into six doses of half a sheet each, and every day, when the toilette begins, take a dose, that is to say, read half a sheet. By this means, it will have the only merit its length and dulness can aspire to, that of a.s.sisting your coiffeuse to procure you six good naps of sleep. I will even allow you twelve days to get through it, holding you rigorously to one condition only, that is, that at whatever hour you receive this, you do not break the seal of the enclosed till the next toilette. Of this injunction I require a sacred execution. I rest it on your friends.h.i.+p, and that in your first letter, you tell me honestly, whether you have honestly performed it. I send you the song I promised. Bring me in return the subject, _Jours heureux!_ Were I a songster, I should sing it all to these words; '_Dans ces lieux qu'elle tarde a se rendre!_' Learn it, I pray you, and sing it with feeling. My right hand presents its devoirs to you, and sees with great indignation the left supplanting it in a correspondence so much valued. You will know the first moment it can resume its rights. The first exercise of them shall be addressed to you, as you had the first essay of its rival. It will yet, however, be many a day. Present my esteem to Mr. Cosway, and believe me to be yours very affectionately,

Th: Jefferson.

LETTER x.x.x.--M. LE ROY DE L'ACADEMIE DES SCIENCES, November 13, 1786

M. LE ROY DE L'ACADEMIE DES SCIENCES.

Paris, November 13, 1786.

Sir,

I received the honor of yours of September the 18th, a day or two after the accident of a dislocated wrist had disabled me from writing. I have waited thus long in constant hope of recovering its use. But finding that this hope walks before me like my shadow, I can no longer oppose the desire and duty of answering your polite and learned letter. I therefore employ my left hand in the office of scribe, which it performs indeed slowly, awkwardly, and badly.

The information given by me to the Marquis de Chastellux, and alluded to in his book and in your letter, was, that the sea breezes which prevail in the lower parts of Virginia, during the summer months, and in the warm parts of-the day, had made a sensible progress into the interior country: that formerly, within the memory of persons living, they extended but little above Williamsburg; that afterwards they became sensible as high as Richmond; and that, at present, they penetrate sometimes as far as the first mountains, which are above an hundred miles further from the sea coast, than Williamsburg is. It is very rare, indeed, that they reach those mountains, and not till the afternoon is considerably advanced. A light northwesterly breeze is, for the most part, felt there, while an easterly or northeasterly wind is blowing strongly in the lower country. How far northward and southward of Virginia, this easterly breeze Takes place, I am not informed. I must, therefore, be understood as speaking of that State only, which extends on the sea coast from 36 1/2 to 38 of lat.i.tude.

This is the fact. We know too little of the operations of nature in the physical world, to a.s.sign causes with any degree of confidence. Willing always, however, to guess at what we do not know, I have sometimes indulged myself with conjectures on the causes of the phenomena above stated. I will hazard them on paper, for your amus.e.m.e.nt, premising for their foundation some principles believed to be true.

Air resting on a heated and reflecting surface, becomes warmer, rarer, and lighter: it ascends therefore, and the circ.u.mjacent air, which is colder and heavier, flows into its place, becomes warmed and lightened in its turn, ascends, and is succeeded as that which went before. If the heated surface be circular, the air flows to it from every quarter, like the rays of a circle to its centre. If it be a zone of determinate breadth and indefinite length, the air will flow from each side perpendicularly on it. If the currents of air flowing from opposite sides, be of equal force, they will meet in equilibrio, at a line drawn longitudinally through the middle of the zone. If one current be stronger than the other, the stronger one will force back the line of equilibrium, towards the further edge of the zone, or even beyond it: the motion it has acquired causing it to overshoot the zone, as the motion acquired by a pendulum in its descent, causes it to vibrate beyond the point of its lowest descent.

Earth, exposed naked to the sun's rays, absorbs a good portion of them; but, being an opaque body, those rays penetrate to a small depth only.

Its surface, by this acc.u.mulation of absorbed rays, becomes considerably heated. The residue of the rays are reflected into the air resting on that surface. This air, then, is warmed, 1. by the direct rays of the sun; 2. by its reflected rays; 3. by contact with the heated surface.

A forest receiving the sun's rays, a part of them enters the intervals between the trees, and their reflection upwards is intercepted by the leaves and boughs. The rest fall on the trees, the leaves of which being generally inclined towards the horizon, reflect the rays downwards. The atmosphere here, then, receives little or no heat by reflection. Again, these leaves having a power of keeping themselves cool by their own transpiration, they impart no heat to the air by contact. Reflection and contact, then, two of the three modes before-mentioned, of communicating heat, are wanting here; and, of course, the air over a country covered by forest must be colder than that over cultivated grounds.

The sea being pellucid, the sun's rays penetrate it to a considerable depth. Being also fluid, and in perpetual agitation, its parts are constantly mixed together; so that instead of its heat being all acc.u.mulated in its surface, as in the case of a solid, opaque body, it is diffused through its whole ma.s.s. Its surface, therefore, is comparatively cool, for these reasons; to which may be added that of evaporation. The small degree of reflection which might otherwise take place, is generally prevented by the rippled state of its surface. The air resting on the sea, then, like that resting on a forest, receives little or no heat by reflection or contact; and is therefore colder than that which lies over a cultivated country.

To apply these observations to the phenomena under consideration. The first settlements of Virginia were made along the sea coast, bearing from the south, towards the north, a little eastwardly. These settlements formed a zone, in which, though every point was not cleared of its forest, yet a good proportion was cleared and cultivated. The cultivated earth, as the sun advances above the horizon in the morning, acquires from it an intense heat, which is retained and increased through the warm parts of the day. The air resting on it becomes warm in proportion, and rises. On one side is a country still covered with forest: on the other is the ocean. The colder air from both of these, then rushes towards the heated zone, to supply the place left vacant there by the ascent of its warm air. The breeze from the west is light and feeble; because it traverses a country covered with mountains and forests, which r.e.t.a.r.d its current. That from the east is strong; as pa.s.sing over the ocean, wherein there is no obstacle to its motion.

It is probable, therefore, that this easterly breeze forces itself far into, or perhaps beyond, the zone which produces it. This zone is, by the increase of population, continually widening into the interior country. The line of equilibrium between the easterly and westerly breezes is, therefore, progressive.

Did no foreign causes intervene, the sea breezes would be a little southwardly of the east, that direction being perpendicular to our coast. But within the tropics, there are winds which blow continually and strongly from the east. This current affects the course of the air, even without the tropics. The same cause, too, which produces a strong motion of the air, from east to west, between the tropics, to wit, the sun, exercises its influence without those limits, but more feebly, in proportion as the surface of the globe is there more obliquely presented to its rays. This effect, though not great, is not to be neglected when the sun is in or near our summer solstice, which is the season of these easterly breezes. The northern air, too, flowing towards the equatorial parts, to supply the vacuum made there by the ascent of their heated air, has only the small rotary motion of the polar lat.i.tudes from which it comes. Nor does it suddenly acquire the swifter rotation of the parts into which it enters. This gives it the effect of a motion opposed to that of the earth, that is to say, of an easterly one. And all these causes together are known to produce currents of air in the Atlantic, varying from east to northeast, as far as the fortieth degree of lat.i.tude. It is this current which presses our sea breeze out of its natural southeasterly direction, to an easterly, and sometimes almost a northeasterly one.

We are led naturally to ask, where the progress of our sea breezes will ultimately be stopped? No confidence can be placed in any answer to this question. If they should ever pa.s.s the mountainous country which separates the waters of the ocean from those of the Mississippi, there may be circ.u.mstances which might aid their further progress, as far as the Mississippi. That mountainous country commences about two hundred miles from the sea coast, and consists of successive ranges pa.s.sing from northeast to southwest, and rising the one above the other to the Allegany Ridge, which is the highest of all. From that, lower and lower ridges succeed one another again, till having covered, in the whole, a breadth of two hundred miles from southeast to northwest, they subside into a plain, fertile country, extending four hundred miles to the Mississippi, and probably much further on the other side, towards the heads of the western waters. When this country shall become cultivated, it will, for the reasons before explained, draw to it winds from the east and west. In this case, should the sea breezes pa.s.s the intermediate mountains, they will rather be aided than opposed in their further progress to the Mississippi. There are circ.u.mstances, however, which render it possible that they may not be able to pa.s.s those intermediate mountains. 1. These mountains const.i.tute the highest lands within the United States. The air on them must consequently be very cold and heavy, and have a tendency to flow both to the east and west. 2.

Ranging across the current of the sea breezes, they are in themselves, so many successive barriers opposed to their progress. 3. The country they occupy is covered with trees, which a.s.sist to weaken and spend the force of the breezes. 4. It will remain so covered; a very small proportion of it being capable of culture. 5. The temperature of its air, then, will never be softened by culture.

Whether in the plain country between the Mississippi and Allegany mountains, easterly or westerly winds prevail at present, I am not informed. I conjecture, however, that they must be westerly: and I think with you, Sir, that if those mountains were to subside into plain country, as their opposition to the westerly winds would then be removed, they would repress more powerfully those from the east, and of course would remove the line of equilibrium nearer to the sea coast for the present.

Having had occasion to mention the course of the tropical winds from east to west, I will add some observations connected with them. They are known to occasion a strong current in the ocean, in the same direction.

This current breaks on that wedge of land of which Saint Roque is the point; the southern column of it probably turning off and was.h.i.+ng the coast of Brazil. I say probably, because I have never heard the fact, and conjecture it from reason only. The northern column, having its western motion diverted towards the north, and reinforced by the currents of the great rivers Orinoko, Amazons, and Tocantin, has probably been the agent which formed the Gulf of Mexico, cutting the American continent nearly in two, in that part. It re-issues into the ocean at the northern end of the Gulf, and pa.s.ses by the name of the Gulf Stream, all along the coast of the United States, to its northern extremity. There it turns off eastwardly, having formed by its eddy, at this turn, the Banks of Newfoundland. Through the whole of its course, from the Gulf to the Banks, it retains a very sensible warmth. The Spaniards are, at this time, desirous of trading to their Philippine Islands, by the way of the Cape of Good Hope: but opposed in it by the Dutch, under authority of the treaty of Munster, they are examining the practicability of a common pa.s.sage through the Straits of Magellan, or round Cape Horn. Were they to make an opening through the Isthmus of Panama, a work much less difficult than some even of the inferior ca.n.a.ls of France, however small this opening should be in the beginning, the tropical current entering it with all its force, would soon widen it sufficiently for its own pa.s.sage, and thus complete in a short time, that work which otherwise will still employ it for ages. Less country, too, would be destroyed by it in this way. These consequences would follow. 1. Vessels from Europe or the western coast of Africa, by entering the tropics, would have a steady wind and tide to carry them through the Atlantic, through America and the Pacific ocean, to every part of the Asiatic coast, and of the eastern coast of Africa: thus performing with speed and safety the tour of the whole globe, to within about twenty-four degrees of longitude, or one fifteenth part of its circ.u.mference; the African continent, under the line, occupying about that s.p.a.ce. 2. The Gulf of Mexico, now the most dangerous navigation in the world on account of its currents and moveable sands, would become stagnant and safe. 3. The Gulf Stream on the coast of the United States would cease, and with that, those derangements of course and reckoning, which now impede and endanger the intercourse with those States. 4. The fogs on the Banks of Newfoundland,* supposed to be the vapors of the Gulf Stream rendered turbid by cold air, would disappear. 5. Those Banks ceasing to receive supplies of sand, weeds, and warm water, by the Gulf Stream, it might become problematical what effect changes of pasture and temperatures would have on the fisheries. However it is time to relieve you from this long lecture. I wish its subject may have been sufficiently interesting to make amends for its details. These are submitted with entire deference to your better judgment. I will only add to them, by a.s.suring you of the sentiments of perfect esteem and respect, with which I have the honor to be, Sir, your most obedient and most humble servant,

Th: Jefferson.

LETTER x.x.xI.--TO GENERAL WAs.h.i.+NGTON, November 14, 1786

TO GENERAL WAs.h.i.+NGTON.

Paris, November 14, 1786.

Sir,

The house of Le Coulteux, which for some centuries has been the wealthiest of this place, has it in contemplation to establish a great company for the fur trade. They propose that partners interested one half in the establishment, should be American citizens, born and residing in the United States. Yet if I understood them rightly, they expect that the half of the company which resides here, should make the greatest part, or perhaps the whole of the advances, while those on our side the water should superintend the details. They had, at first, thought of Baltimore as the centre of their American transactions. I have pointed out to them the advantages of Alexandria for this purpose.

They have concluded to take information as to Baltimore, Philadelphia, and New York, for a princ.i.p.al deposit, and having no correspondent at Alexandria, have asked me to procure a state of the advantages of that place, as also to get a recommendation of the best merchant there, to be adopted as partner and head of the business there. Skill, punctuality, and integrity are the requisites in such a character. They will decide on their whole information, as to the place for their princ.i.p.al factory.
