That is as follows. They all suppose the earth a created existence. They must suppose a creator then; and that he possessed power and wisdom to a great degree. As he intended the earth for the habitation of animals and vegetables, is it reasonable to suppose, he made two jobs of his creation, that he first made a chaotic lump and set it into rotatory motion, and then waited the millions of ages necessary to form itself? That when it had done this, he stepped in a second time, to create the animals and plants which were to inhabit it? As the hand of a creator is to be called in, it may as well be called in at one stage of the process as another. We may as well suppose he created the earth at once, nearly in the state in which we see it, fit for the preservation of the beings he placed on it. But it is said, we have a proof that he did not create it in its present solid form, but in a state of fluidity; because its present shape of an oblate spheroid is precisely that which a fluid mass revolving on its axis would assume.
I suppose that the same equilibrium between gravity and centrifugal force, which would determine a fluid mass into the form of an oblate spheroid, would determine the wise creator of that mass, if he made it in a solid state, to give it the same spheroidical form. A revolving fluid will continue to change its shape, till it attains that in which its principles of contrary motion are balanced. For if you suppose them not balanced, it will change its form. Now, the same balanced form is necessary for the preservation of a revolving solid. The creator, therefore, of a revolving solid, would make it an oblate spheroid, that figure alone admitting a perfect equilibrium. He would make it in that form, for another reason; that is, to prevent a shifting of the axis of rotation. Had he created the earth perfectly spherical its axis might have been perpetually shifting, by the influence of the other bodies of the system; and by placing the inhabitants of the earth successively under its poles, it might have been depopulated; whereas, being spheroidical, it has but one axis on which it can revolve in equilibrio. Suppose the axis of the earth to shift forty-five degrees; then cut it into one hundred and eighty slices, making every section in the plane of a circle of latitude, perpendicular to the axis: every one of these slices, except the equatorial one, would be unbalanced, as there would be more matter on one side of its axis than on the other. There could be but one diameter drawn through such a slice, which would divide it into two equal parts. On every other possible diameter, the parts would hang unequal. This would produce an irregularity in the diurnal rotation. We may, therefore, conclude it impossible for the poles of the earth to shift, if it was made spheroidically; and that it would be made spheroidical, though solid, to obtain this end. I use this reasoning only on the supposition that the earth has had a beginning. I am sure I shall read your conjectures on this subject with great pleasure, though I bespeak, beforehand, a right to indulge my natural incredulity and scepticism. The pain in which I write awakens me here from my reverie, and obliges me to conclude with compliments to Mrs. Thompson, and assurances to yourself of the esteem and affection with which I am sincerely, dear Sir, your friend and servant.
P. S. Since writing the preceding, I have had a conversation on the subject of the steam mills, with the famous Boulton, to whom those of London belong, and who is here at this time. He compares the effect of steam with that of horses, in the following manner: Six horses, aided with the most advantageous combination of the mechanical powers hitherto tried, will grind six bushels of flour in an hour; at the end of which time they are all in a foam, and must rest. They can work thus, six hours in the twenty-four, grinding thirty-six bushels of flour, which is six to each horse, for the twenty-four hours. His steam mill in London consumes one hundred and twenty bushels of coal in twenty-four hours, turns ten pair of stones, which grind eight bushels of flour an hour each, which is nineteen hundred and twenty bushels in the twenty-four hours. This makes a peck and a half of coal perform exactly as much as a horse, in one day, can perform.
TO COLONEL MONROE
Dear Sir,—Your letters of August the 19th and October the 12th, have come duly to hand. My last to you was of the 11th of August. Soon after that date I got my right wrist dislocated, which has, till now, deprived me of the use of that hand; and even now, I can use it but slowly, and with pain. The revisal of the Congressional intelligence contained in your letters, makes me regret the loss of it on your departure. I feel, too, the want of a person there, to whose discretion I can trust confidential communications, and on whose friendship I can rely against the unjust designs of malevolence. I have no reason to suppose I have enemies in Congress; yet it is too possible to be without that fear. Some symptoms make me suspect, that my proceedings to redress the abusive administration of tobacco by the Farmers General have indisposed towards me a powerful person in Philadelphia, who was profiting from that abuse. An expression in the enclosed letter of M. de Calonnes, would seem to imply, that I had asked the abolition of Mr. Morris's contract. I never did. On the contrary, I always observed to them, that it would be unjust to annul that contract. I was led to this, by principles both of justice and interest. Of interest, because that contract would keep up the price of tobacco here, to thirty-four, thirty-six, and thirty-eight livres, from which it will fall when it shall no longer have that support. However, I have done what was right, and I will not so far wound my privilege of doing that, without regard to any man's interest, as to enter into any explanations of this paragraph with him. Yet I esteem him highly, and suppose that hitherto he had esteemed me. You will see by Calonnes' letter, that we are doing what we can, to get the trade of the United States put on a good footing. I am now about setting out on a journey to the south of France, one object of which is to try the mineral waters there, for the restoration of my hand; but another is, to visit all the seaports where we have trade, and to hunt up all the inconveniences under which it labors, in order to get them rectified. I shall visit, and carefully examine too, the canal of Languedoc. On my return, which will be early in the spring, I shall send you several livraisons of the Encyclopedie, and the plan of your house. I wish to heaven, you may continue in the disposition to fix it in Albemarle. Short will establish himself there, and perhaps Madison may be tempted to do so. This will be society enough, and it will be the great sweetener of our lives. Without society, and a society to our taste, men are never contented. The one here supposed, we can regulate to our minds, and we may extend our regulations to the sumptuary department, so as to set a good example to a country which needs it, and to preserve our own happiness clear of embarrassment. You wish not to engage in the drudgery of the bar. You have two asylums from that. Either to accept a seat in the Council, or in the judiciary department. The latter, however, would require a little previous drudgery at the bar, to qualify you to discharge your duty with satisfaction to yourself. Neither of these would be inconsistent with a continued residence in Albemarle. It is but twelve hours' drive in a sulky from Charlottesville to Richmond, keeping a fresh horse always at the half-way, which would be a small annual expense. I am in hopes that Mrs. M. will have in her domestic cares, occupation and pleasure, sufficient to fill her time, and insure her against the tedium vitæ: that she will find, that the distractions of a town, and the waste of life under these, can bear no comparison with the tranquil happiness of domestic life. If her own experience has not yet taught her this truth, she has in its favor the testimony of one who has gone through the various scenes of business, of bustle, of office, of rambling, and of quiet retirement, and who can assure her, that the latter is the only point upon which the mind can settle at rest. Though not clear of inquietudes, because no earthly situation is so, they are fewer in number, and mixed with more objects of contentment, than in any other mode of life. But I must not philosophise too much with her, lest I give her too serious apprehensions of a friendship I shall impose on her. I am with very great esteem, dear Sir, your sincere friend and servant.
TO HIS EXCELLENCY MR. ADAMS
Dear Sir,—Colonel Franks will have the honor of delivering you the treaty with the Emperor of Morocco, and all its appendages. You will perceive, by Mr. Barclay's letter, that it is not necessary that any body should go back to Morocco to exchange ratifications. He says, however, that it will be necessary that Fennish receive some testimony that we approve the treaty; and as, by the acts of Congress, our signature is necessary to give validity to it, I have had duplicates of ratifications prepared, which I have signed, and now send you. If you approve and sign them, send one back to me to be forwarded to Fennish,
