СКАЧАТЬ not the college of the literary societies of the world adopt the second pendulum as the unit of measure on the authorities of reason, convenience and common consent? And why should not our society open the proposition by a circular letter to the other learned institutions of the earth? If men of science, in their publications, would express measures always in multiples and decimals of the pendulum, annexing their value in municipal measures as botanists add the popular to the botanical names of plants, they would soon become familiar to all men of instruction, and prepare the way for legal adoptions. At any rate, it would render the writers of every nation intelligible to the readers of every other, when expressing the measures of things. The French, I believe, have given up their Decada Calendar, but it does not appear that they retire from the centesimal division of the quadrant. On the contrary, M. Borda has calculated according to that division, new trigonometrical tables not yet, I believe, printed. In the excellent tables of Callet, lately published by Didot, in stereotype, he has given a table of Logarithmic lines and tangents for the hundred degrees of the quadrant, abridged from Borda's manuscript. But he has given others for the sexagesimal division, which being for every 10´´ through the whole table, are more convenient than Hutton's, Scherwin's, or any of their predecessors. It cannot be denied that the centesimal division would facilitate our arithmetic, and that it might have been preferable had it been originally adopted, as a numeration by eighths would have been more convenient than by tens. But the advantages would not now compensate the embarrassments of a change.

      I extremely regret the not being provided with a time-piece equal to the observations of the approaching eclipse of the sun. Can you tell me what would be the cost in Philadelphia of a clock, the time-keeping part of which should be perfect? And what the difference of cost between a wooden and gridiron pendulum? To be of course without a striking apparatus, as it would be wanted for astronomical purposes only. Accept assurances of affectionate esteem and respect.

      TO CLEMENT CAINE, ESQ

Monticello, September 16, 1811.

      Sir,—Your favor of April 2d was not received till the 23d of June last, with the volume accompanying it, for which be pleased to accept my thanks. I have read it with great satisfaction, and received from it information, the more acceptable as coming from a source which could be relied on. The retort on European censors, of their own practices on the liberties of man, the inculcation on the master of the moral duties which he owes to the slave, in return for the benefits of his service, that is to say, of food, clothing, care in sickness, and maintenance under age and disability, so as to make him in fact as comfortable and more secure than the laboring man in most parts of the world; and the idea suggested of substituting free whites in all household occupations and manual arts, thus lessening the call for the other kind of labor, while it would increase the public security, give great merit to the work, and will, I have no doubt, produce wholesome impressions. The habitual violation of the equal rights of the colonist by the dominant (for I will not call them the mother) countries of Europe, the invariable sacrifice of their highest interests to the minor advantages of any individual trade or calling at home, are as immoral in principle as the continuance of them is unwise in practice, after the lessons they have received. What, in short, is the whole system of Europe towards America but an atrocious and insulting tyranny? One hemisphere of the earth, separated from the other by wide seas on both sides, having a different system of interests flowing from different climates, different soils, different productions, different modes of existence, and its own local relations and duties is made subservient to all the petty interests of the other, to their laws, their regulations, their passions and wars, and interdicted from social intercourse, from the interchange of mutual duties and comforts with their neighbors, enjoined on all men by the laws of nature. Happily these abuses of human rights are drawing to a close on both our continents, and are not likely to survive the present mad contest of the lions and tigers of the other. Nor does it seem certain that the insular colonies will not soon have to take care of themselves, and to enter into the general system of independence and free intercourse with their neighboring and natural friends. The acknowledged depreciation of the paper circulation of England, with the known laws of its rapid progression to bankruptcy, will leave that nation shortly without revenue, and without the means of supporting the naval power necessary to maintain dominion over the rights and interests of different nations. The intention too, which they now formally avow, of taking possession of the ocean as their exclusive domain, and of suffering no commerce on it but through their ports, makes it the interest of all mankind to contribute their efforts to bring such usurpations to an end. We have hitherto been able to avoid professed war, and to continue to our industry a more salutary direction. But the determination to take all our vessels bound to any other than her ports, amounting to all the war she can make (for we fear no invasion), it would be folly in us to let that war be all on one side only, and to make no effort towards indemnification and retaliation by reprisal. That a contest thus forced on us by a nation a thousand leagues from us both, should place your country and mine in relations of hostility, who have not a single motive or interest but of mutual friendship and interchange of comforts, shows the monstrous character of the system under which we live. But however, in the event of war, greedy individuals on both sides, availing themselves of its laws, may commit depredations on each other, I trust that our quiet inhabitants, conscious that no cause exists but for neighborly good will, and the furtherance of common interests, will feel only those brotherly affections which nature has ordained to be those of our situation.

      A letter of thanks for a good book has thus run away from its subject into fields of speculation into which discretion perhaps should have forbidden me to enter, and for which an apology is due. I trust that the reflections I hazard will be considered as no more than what they really are, those of a private individual, withdrawn from the councils of his country, uncommunicating with them, and responsible alone for any errors of fact or opinion expressed; as the reveries, in short, of an old man, who, looking beyond the present day, looks into times not his own, and as evidences of confidence in the liberal mind of the person to whom they are so freely addressed. Permit me, however, to add to them my best wishes for his personal happiness, and assurances of the highest consideration and respect.

      TO MR. EPPES

Monticello, September 29, 1811.

      Dear Sir,—The enclosed letter came under cover to me without any indication from what quarter it came.

      Our latest arrival brings information of the death of the king of England. Its coming from Ireland and not direct from England would make it little worthy of notice, were not the event so probable. On the 26th of July the English papers say he was expected hourly to expire. This vessel sailed from Ireland the 4th of August, and says an express brought notice the day before to the government that he died on the 1st; but whether on that day or not, we may be certain he is dead, and entertain, therefore, a hope that a change of ministers will produce that revocation of the orders of council for which they stand so committed. In this event we may still remain at peace, and that probably concluded between the other powers. I am so far, in that case, from believing that our reputation will be tarnished by our not having mixed in the mad contests of the rest of the world that, setting aside the ravings of pepper-pot politicians, of whom there are enough in every age and country, I believe it will place us high in the scale of wisdom, to have preserved our country tranquil and prosperous during a contest which prostrated the honor, power, independence, laws and property of every country on the other side of the Atlantic. Which of them have better preserved their honor? Has Spain, has Portugal, Italy, Switzerland, Holland, Prussia, Austria, the other German powers, Sweden, Denmark, or even Russia? And would we accept of the infamy of France or England in exchange for our honest reputation, or of the result of their enormities, despotism to the one, and bankruptcy and prostration to the other, in exchange for the prosperity, the freedom and independence which we have preserved safely through the wreck? The bottom of my page warns me it is time to present my homage to Mrs. Eppes, and to yourself and Francis my affectionate adieux.
