which endeavors have been made to investigate the passage of Annibal over the Alps, and was just able to satisfy myself, from a view of the country, that the descriptions given of his march are not sufficiently particular to enable us at this day even to guess at his track across the Alps. In architecture, painting, sculpture, I found much amusement: but more than all in their agriculture, many objects of which might be adopted with us to great advantage. I am persuaded there are many parts of our lower country where the olive tree might be raised, which is assuredly the richest gift of heaven. I can scarcely except bread. I see this tree supporting thousands in among the Alps where there is not soil enough to make bread for a single family. The caper too might be cultivated with us. The fig we do raise. I do not speak of the vine, because it is the parent of misery. Those who cultivate it are always poor, and he who would employ himself with us in the culture of corn, cotton, &c. can procure in exchange much more wine, & better than he could raise by its direct culture. I sent you formerly copies of the documents on the Tagliaferro family which I had received from Mr. Febroni. I now send the originals. I have procured for you a copy of Polybius, the best edition; but the best edition of Vitruvius, which is with the commentaries of Ticinus, is not to be got here. I have sent to Holland for it. In the mean time the Polybius comes in a box containing books for Peter Carr & for some of my friends in Williamsburg & it's vicinities. I have taken the liberty of addressing this box to you.

It goes to New York in the packet boat which carries this letter, & will be forwarded to you by water, by Mr. Madison. Its freight to New York is paid here. The transportation from thence to Williamsburgh will be demanded of you, and shall stand as the equivalent to the cost of Polybius & Vitruvius if you please. The difference either way will not be worth the trouble of erecting & transmitting accounts. I send you herewith a state of the contents of the box, and for whom each article is. Among these are some as you will perceive, of which I ask your acceptance. It is a great comfort to me that while here I am able to furnish some amusement to my friends by sending them such productions of genius, antient & modern, as might otherwise escape them; and I hope they will permit me to avail myself of the occasion, while it lasts. This world is going all to war. I hope our's will remain clear of it. It is already declared between the Turks & Russians, and, considering the present situation of Holland, it cannot fail to spread itself all over Europe. Perhaps it may not be till the next spring that the other powers will be engaged in it: nor is it as yet clear how they will arrange themselves. I think it not impossible that France & the two empires may join against all the rest. The Patriotic party in Holland will be saved by this, and the Turks sacrificed. The only thing which can prevent the union of France & the two empires, is the difficulty of agreeing about the partition of the spoils. Constantinople is the key of Asia. Who shall have it is the question? I cannot help

looking forward to the reestablishment of the Greeks as a people, and the language of Homer becoming again a living language, as among possible events. You have now with you Mr. Paradise, who can tell you how easily the modern may be improved into the antient Greek. You ask me in your letter what ameliorations I think necessary in our federal constitution. It is now too late to answer the question, and it would always have been presumption in me to have done it. Your own ideas & those of the great characters who were to be concerned with you in these discussions will give the law, as they ought to do, to us all. My own general idea was that the states should severally preserve their sovereignty in whatever concerns themselves alone, & that whatever may concern another state, or any foreign nation, should be made a part of the federal sovereignty. That the exercise of the federal sovereignty should be divided among three several bodies, legislative, executive, & judiciary, as the state sovereignties are: and that some peaceable means should be contrived for the federal head to enforce compliance on the part of the states. I have reflected on your idea of wooden or ivory diagrams for the geometrical demonstrations. I should think wood as good as ivory; & that in this case it might add to the improvement of the young gentlemen; that they should make the figures themselves. Being furnished by a workman with a piece of veneer, no other tool than a penknife & a wooden rule would be necessary. Perhaps pasteboards, or common cards might be still more convenient. The

difficulty is, how to reconcile figures which must have a very sensible breadth, to our ideas of a mathematical line, which, having neither breadth nor thickness, will revolt more at these than at simple lines drawn on paper or slate. If after reflecting on this proposition you would prefer having them made here, lay your commands on me and they shall be executed.

I return you a thousand thousand thanks for your goodness to my nephew. After my debt to you for whatever I am myself, it is increasing it too much to interest yourself for his future fortune. But I know that, to you, a consciousness of doing good is a luxury ineffable. You have enjoyed it already beyond all human measure, and that you may long live to enjoy it and to bless your country & friends is the sincere. prayer of him who is with every possible sentiment of esteem & respect, dear Sir, your most obedient & most humble servant.

TO CHARLES THOMSON.

J. MSS. PARIS Sep. 20, 1787.

DEAR SIR,-Your favor of April 28 did not come to my hands till the 1st inst. Unfortunately the boxes of plants, which were a day too late to come by the April packet, missed the packet of June 10 also, & only came by that of July 25. They are not yet arrived at Paris, but I expect them daily. I am sensible of your kind attention to them, and that as you were leaving New York you took the course which bade fair to be the best. That they were forgotten in the hands in which you placed them, was

probably owing to too much business & more important. I have desired Mr. Madison to refund to you the money you were so kind as to advance for me. The delay of your letter will apologize for this delay of the repayment. I thank you also for the extract of the letter you were so kind as to communicate to me on the antiquities found in the Western country. I wish that the persons who go thither would make very exact descriptions of what they see of that kind, without forming any theories. The moment a person forms a theory his imagination sees in every object only the traits which favor that theory. But it is too early to form theories on those antiquities. We must wait with patience till more facts are collected. I wish your philosophical society would collect exact descriptions of the several monuments as yet known, and insert them naked in their Transactions, and continue their attention to those hereafter to be discovered. Patience & observation may enable us in time to solve the problem whether those who formed the scattering monuments in our Western country, were colonies sent off from Mexico, or the founders of Mexico itself? Whether both were the descendants or the progenitors of the Asiatic redmen. The Mexican tradition mentioned by Dr. Robertson, is an evidence, but a feeble one, in favor of the one opinion. The number of languages radically different, is a strong evidence in favor of the contrary one. There is an American of the name of Ledyard, he who was with Captain Cook on his last voyage & wrote an account of that voyage, who is gone to St.
