MARSEILLES, May 6, 1787. SIR,--A desire of seeing a commerce commenced between the dominions of His Majesty, the King of Sardinia, and the United States of America, and a direct exchange of their respective productions, without passing through a third nation, led me into the conversation which I had the honor of having with you on that subject, and afterwards with Monsieur Tallon, at Turin, to whom I promised that I would explain to you, in writing, the substance of what passed between us. The articles of your produce wanted with us, are brandies, wines, oil, fruits, and manufactured silks: those with which we can furnish you, are indigo, potash, tobacco, flour, salt fish, furs and peltries, ships and materials for building them. The supply of tobacco, particularly, being in the hands of government solely, appeared to me to offer an article for beginning immediately the experiment of direct commerce. That of the first quality can be had, at first hand, only from James river, in Virginia; those of the second and third, from the same place and from Baltimore, in Maryland. The first quality is delivered in the ports of France at thirty-eight livres the quintal, the second at thirty-six livres, the third at thirty-four livres, weight and money of France, by individuals generally. I send you the copy of a large contract, wherein the three qualities are averaged at thirty-six livres. They may be delivered at Nice for those prices. Indeed, it is my opinion, that by making shipments of your own produce to those places, and buying the tobaccos on the spot, they may be had more advantageously. In this case, it would be expedient that merchants of Nice, Turin, and America, should form a joint concern for conducting the business in the two countries. Monsieur Tallon desired me to point out proper persons in America, who might be addressed for this purpose. The house of the most extensive reputation, concerned in the tobacco trade, and on the firmest funds, is that of Messrs. Ross and Pleasants, at Richmond, in Virginia. If it should be concluded, on your part, to make any attempt of this kind, and to address yourselves to these gentlemen, or any others, it would be the best to write them your ideas, and receive theirs, before you make either purchases or shipments. A more hasty conduct might occasion loss, and retard, instead of encouraging the establishment of this commerce. I would undertake to write, at the same time, to these, or any other merchants whom you should prefer, in order to dispose them favorably, and as disinterestedly as possible, for the encouragement of this essay. I must observe to you, that our vessels are fearful of coming into the Mediterranean on account of the Algerines; and that, if you should freight vessels, those of the French will be most advantageous for you, because received into our ports without paying any duties on some of those articles, and lighter than others on all of them. English vessels, on the other hand, are
