Accept my affectionate salutations. TO MR. HARRIS. WASHINGTON, April 18, 1806. SIR,--It is now some time since I received from you, through the house of Smith and Buchanan at Baltimore, a bust of the Emperor Alexander, for which I have to return you my thanks. These are the more cordial, because of the value the bust derives from the great estimation in which its original is held by the world, and by none more than by myself. It will constitute one of the most valued ornaments of the retreat I am preparing for myself at my native home. Accept, at the same time, my acknowledgments for the elegant work of Atkinson and Walker on the customs of the Russians. I had laid it down as a law for my conduct while in office, and hitherto scrupulously observed, to accept of no present beyond a book, a pamphlet, or other curiosity of minor value; as well to avoid imputation on my motives of action, as to shut out a practice susceptible of such abuse. But my particular esteem for the character of the Emperor, places his image in my mind above the scope of law. I receive it, therefore, and shall cherish it with affection. It nourishes the contemplation of all the good placed in his power, and of his disposition to do it. A little before Dr. Priestley's death, he informed me that he had received intimations, through a channel he confided in, that the Emperor entertained a wish to know something of our Constitution. I have therefore selected the two best works we have on that subject, for which I pray you to ask a place in his library. They are too much in detail to occupy his time; but they will furnish materials for an abstract, to be made by others, on such a scale as may bring the matter within the compass of the time which his higher callings can yield to such an object.
