Dear Sir,—Repeated inquiries on the part of Senator Tracy what has become of his book, (the MS. I last sent you,) oblige me to ask of you what I shall say to him. I congratulate you on the brilliant affair of the Enterprise and Boxer. No heart is more rejoiced than mine at these mortifications of English pride, and lessons to Europe that the English are not invincible at sea. And if these successes do not lead us too far into the navy mania, all will be well. But when are to cease the severe lessons we receive by land, demonstrating our want of competent officers? The numbers of our countrymen betrayed into the hands of the enemy by the treachery, cowardice or incompetence of our high officers, reduce us to the humiliating necessity of acquiescing in the brutal conduct observed towards them. When, during the last war, I put Governor Hamilton and Major Hay into a dungeon and in irons for having themselves personally done the same to the American prisoners who had fallen into their hands, and was threatened with retaliation by Philips, then returned to New York, I declared to him I would load ten of their Saratoga prisoners (then under my care and within half a dozen miles of my house) with double irons for every American they should misuse under pretence of retaliation, and it put an end to the practice. But the ten for one are now with them. Our present hopes of being able to do something by land seem to rest on Chauncey. Strange reverse of expectations that our land force should be under the wing of our little navy. Accept the assurance of my esteem and respect.

TO MR. ISAAC M'PHERSON.

Monticello, September 18, 1813.

Sir,—I thank you for the communication of Mr. Jonathan Ellicot's letter in yours of August 28th, and the information it conveys. With respect to mine of August 13th, I do not know that it contains anything but what any man of mathematical reading may learn from the same sources; however, if it can be used for the promotion of right, I consent to such an use of it. Your inquiry as to the date of Martin's invention of the drill plough, with a leathern band and metal buckets, I cannot precisely answer; but I received one from him in 1794, and have used it ever since for sowing various seeds, chiefly peas, turnips, and benni. I have always had in mind to use it for wheat; but sowing only a row at a time, I had proposed to him some years ago to change the construction so that it should sow four rows at a time, twelve inches apart; and I have been waiting for this to be done either by him or myself; and have not, therefore, commenced that use of it. I procured mine at first through Col. John Taylor of Caroline, who had been long in the use of it, and my impression was that it was not then a novel thing. Mr. Martin is still living, I believe. If not, Colonel Taylor, his neighbor, probably knows its date. If the bringing together under the same roof various useful things before known, which you mention as one of the grounds of Mr. Evans' claim, entitles him to an exclusive use of all these, either separately or combined, every utensil of life might be taken from us by a patent. I might build a stable, bring into it a cutting-knife to chop straw, a hand-mill to grind the grain, a curry comb and brush to clean the horses, and by a patent exclude every one from ever more using these things without paying me. The elevator, the conveyer, the hopper-boy, are distinct things, unconnected but by juxtaposition. If no patent can be claimed for any one of these separately, it cannot be for all of them,—several nothings put together cannot make a something;—this would be going very wide of the object of the patent laws. I salute you with esteem and respect.

TO MR. JAMES MARTIN.

Monticello, September 20, 1813.

Sir,—Your letter of August 20th, enabled me to turn to mine of February 23d, 1798, and your former one of February 22d, 1801, and to recall to my memory the oration at Jamaica, which was the subject of them. I see with pleasure a continuance of the same sound principles in the address to Mr. Quincy. Your quotation from the former paper alludes, as I presume, to the term of office to our Senate; a term, like that of the judges, too long for my approbation. I am for responsibilities at short periods, seeing neither reason nor safety in making public functionaries independent of the nation for life, or even for long terms of years. On this principle I prefer the Presidential term of four years, to that of seven years, which I myself had at first suggested, annexing to it, however, ineligibility forever after; and I wish it were now annexed to the 2d quadrennial election of President.

The conduct of Massachusetts, which is the subject of your address to Mr. Quincy, is serious, as embarrassing the operations of the war, and jeopardizing its issue; and still more so, as an example of contumacy against the Constitution. One method of proving their purpose, would be to call a convention of their State, and to require them to declare themselves members of the Union, and obedient to its determinations, or not members, and let them go. Put this question solemnly to their people, and their answer cannot be doubtful. One half of them are republicans, and would cling to the Union from principle. Of the other half, the dispassionate part would consider, 1st. That they do not raise bread sufficient for their own subsistence, and must look to Europe for the deficiency, if excluded from our ports, which vital interests would force us to do. 2d. That they are navigating people without a stick of timber for the hull of a ship, nor a pound of anything to export in it, which would be admitted at any market. 3d. That they are also a manufacturing people, and left by the exclusive system of Europe without a market but ours. 4th. That as the rivals of England in manufactures, in commerce, in navigation, and fisheries, they would meet her competition in every point. 5th. That England would feel no scruples in making the abandonment and ruin of such a rival the price of a treaty with the producing States; whose interest too it would be to nourish a navigation beyond the Atlantic, rather than a hostile one at our own door. And 6th. That in case of war with the Union, which occurrences between coterminous nations frequently produce, it would be a contest of one against fifteen. The remaining portion of the Federal moiety of the State would, I believe, brave all these obstacles, because they are monarchists in principle, bearing deadly hatred to their republican fellow-citizens, impatient under the ascendency of republican principles, devoted in their attachment to England, and preferring to be placed under her despotism, if they cannot hold the helm of government here. I see, in their separation, no evil but the example, and I believe that the effect of that would be corrected by an early and humiliating return to the Union, after losing much of the population of their country, insufficient in its own resources to feed her numerous inhabitants, and inferior in all its allurements to the more inviting soils, climates, and governments of the other States. Whether a dispassionate discussion before the public, of the advantages and disadvantages of separation to both parties, would be the best medicine for this dialytic fever, or to consider it as sacrilege ever to touch the question, may be doubted. I am, myself, generally disposed to indulge, and to follow reason; and believe that in no case would it be safer than in the present. Their refractory course, however, will not be unpunished by the indignation of their co-States, their loss of influence with them, the censures of history, and the stain on the character of their State. With my thanks for the paper enclosed, accept the assurance of my esteem and respect.

TO DOCTOR LOGAN.
