I write this letter without knowing where it will find you. But wherever that may be, I am sure it will find you engaged in something instructive for man. If at Paris, you are of course in habits of society with Mr. Gallatin, our worthy, our able, and excellent minister, who will give you, from time to time, the details of the progress of a country in whose prosperity you are so good as to feel an interest, and in which your name is revered among those of the great worthies of the world. God bless you, and preserve you long to enjoy the gratitude of your fellow men, and to be blessed with honors, health and happiness. TO M. DE MARBOIS. MONTICELLO, June 14, 1817. I thank you, dear Sir, for the copy of the interesting narrative of the Complet d'Arnold, which you have been so kind as to send me. It throws light on that incident of history which we did not possess before. An incident which merits to be known, as a lesson to mankind, in all its details. This mark of your attention recalls to my mind the earlier period of life at which I had the pleasure of your personal acquaintance, and renews the sentiments of high respect and esteem with which that acquaintance inspired me. I had not failed to accompany your personal sufferings during the civil convulsions of your country, and had sincerely sympathized with them.

Had Bonaparte reflected that such is the moral construction of the world, that no national crime passes unpunished in the long run, he would not now be in the cage of St. Helena; and were your present oppressors to reflect on the same truth, they would spare to their own countries the penalties on their present wrongs which will be inflicted on them on future times. The seeds of hatred and revenge which they are now sowing with a large hand, will not fail to produce their fruits in time. Like their brother robbers on the highway, they suppose the escape of the moment a final escape, and deem infamy and future risk countervailed by present gain. Our lot has been happier. When you witnessed our first struggles in the war of independence, you little calculated, more than we did, on the rapid growth and prosperity of this country; on the practical demonstration it was about to exhibit,
