To P. S. Dupont de Nemours Monticello, June 28, 1809

The Letters of Thomas Jefferson DEAR SIR,

-- The interruption of our commerce with England, produced by our embargo and non-intercourse law, and the general indignation excited by her barefaced attempts to make us accessories and tributaries to her usurpations on the high seas, have generated in this country an universal spirit for manufacturing for ourselves, and of reducing to a minimum the number of articles for which we are dependent on her. The advantages, too, of lessening the occasions of risking our peace on the ocean, and of planting the consumer in our own soil by the side of the grower of produce, are so palpable, that no temporary suspension of injuries on her part, or agreements founded on that, will now prevent our continuing in what we have begun. The spirit of manufacture has taken deep root among us, and its foundations are laid in too great expense to be abandoned. The bearer of this, Mr. Ronaldson, will be able to inform you of the extent and perfection of the works produced here by the late state of things; and to his information, which is greatest as to what is doing in the cities, I can add my own as to the country, where the principal articles wanted in every family are now fabricated within itself. This mass of household manufacture, unseen by the public eye, and so much greater than what is seen, is such at present, that let our intercourse with England be opened when it may, not one half the amount of what we have heretofore taken from her will ever again be demanded. The great call from the country has hitherto been of coarse goods. These are now made in our families, and the advantage is toosensible ever to be relinquished. It is one of those obvious improvements in our condition which needed only to be once forced on our attention, never again to be abandoned.

Among the arts which have made great progress among us is that of printing. Heretofore we imported our books, and with them much political principle from England. We now print a great deal, and shall soon supply ourselves with most of the books of considerable demand. But the foundation of printing, you know, is the type-foundry, and a material essential to that is antimony. Unfortunately that mineral is not among those as yet found in the United States, and the difficulty and dearness of getting it from England, will force us to discontinue our type-founderies, and resort to her again for our books, unless some new source of supply can be found. The bearer, Mr. Ronaldson, is of the concern of Binney & Ronaldson, type-founders of Philadelphia. He goes to France for the purpose of opening some new source of supply, where we learn that this article is abundant; the enhancement of the price in England has taught us the fact, that its exportation thither from France must be interrupted, either by the war or express prohibition. Our relations, however, with France, are too unlike hers with England, to place us under the same interdiction. Regulations for preventing the transportation of the article to England, under the cover of supplies to America, may be thought requisite. The bearer, I am persuaded, will readily give any assurances which may be required for this object, and the wants of his own type-foundry here are a sufficient pledge that what he gets is bona fide to supply them. I do not know that there will be any obstacle to his bringing from France any quantity of antimony he may have occasion for; but lest there should be, I have taken the liberty of recommending him to your patronage. I know your enlightened and liberal views on subjects of this kind, and the friendly interest you take in whatever concerns our welfare. I place Mr. Ronaldson, therefore, in your hands, and pray you to advise him, and patronize the object which carries him to Europe, and is so interesting to him and to our country. His knowledge of what is passing among us will be a rich source of information for you, and especially as to the state and progress of our manufactures.

Your kindness to him will confer an obligation on me, and will be an additional title to the high and affectionate esteem and respect of an ancient and sincere friend.
