SIR,--I have read with very great satisfaction the sheets of your work on the commerce of France and the United States, which you were so good as to put into my hands. I think you treat the subject, as far as these sheets go, in an excellent manner. Were I to select any particular passages as giving me particular satisfaction, it would be those wherein you prove to the United States that they will be more virtuous, more free and more happy, employed in agriculture, than as carriers or manufacturers. It is a truth, and a precious one for them, if they could be persuaded of it. I am also particularly pleased with your introductions. You have properly observed that we can no longer be called Anglo-Americans. That appellation now describes only the inhabitants of Nova Scotia, Canada, &c. I had applied that of Federo Americans to our citizens, as it would not be so decent for us to assume to ourselves the flattering appellation of free Americans. There are two passages in this work on which I am able to give information. The first is in page 62; "ils auront le caton quand ils voudront se leiver à cegenre de culturé," and the note "l'on voit dans la Eaie de Massachusetts." The four southernmost States make a great deal of cotton. Their poor are almost entirely clothed in it in winter and summer. In winter they wear shirts of it, and outer clothing of cotton and wool mixed. In summer their shirts are linen, but the outer clothing cotton. The dress of the women is almost entirely of cotton manufactured by themselves, except the richer class, and even many of these wear a good deal of home-spun cotton. It is as well manufactured as the calicoes of Europe. Those four States furnish a great deal of cotton to the States north of them, who cannot make it, as being too cold. There is no neighborhood in any part of the United States without a water-grist mill for grinding the corn of the neighborhood. Virginia, Maryland, Pennsylvania, Delaware, New Jersey, New York, abound with large manufacturing mills for the exportation of flour. There are abundance of saw-mills in all the States. Furnaces and forges of iron, I believe, in every State, I know they are in the nine northernmost. There are many mills for plating and slitting iron. And I think there are many distilleries of rum from Norfolk, in Virginia, to Portsmouth, in New Hampshire. I mention these circumstances because your note seems to imply that these things are only in the particular States you mention.
