In the ensuing autumn, I shall be sending on to Philadelphia a grandson of about fifteen years of age, to whom I shall ask your friendly attentions. Without that bright fancy which captivates, I am in hopes he possesses sound judgment and much observation; and, what I value more than all things, good humor. For thus I estimate the qualities of the mind; 1, good humor, 2, integrity; 3, industry; 4, science. The preference of the first to the second quality may not at first be acquiesced in; but certainly we had all rather associate with a good-humored, light-principled man, than with an ill tempered rigorist in morality. We are here in hourly expectation of seeing Mr. Rose, and of knowing what turn his mission is to give to our present differences. The embargo is salutary. It postpones war, gives time and the benefits of events which that may produce; particularly that of peace in Europe, which will postpone the causes of difference to the next war. I salute you with great affection and respect. TO JOHN TAYLOR, ESQ. WASHINGTON, January 6, 1808. DEAR SIR,--Your ingenious friend, Mr. Martin, formerly made for me a drill of very fine construction. I am now very desirous of sending one of them to the Agricultural Society of Paris, with whom I am in correspondence, and who are sending me a plough supposed to be of the best construction ever known. On trial with their best ploughs, by a dynamometer, it is drawn by from one-half to two-thirds of the force requisite to their best former ploughs. Will you be so good as to get Mr. Martin to make me one of his best drills, sparing no pains to make the workmanship worthy of the object, to pack it in a box, and contrive it for me to Fredericksburg. The cost shall be remitted him as soon as known. I see by the agricultural transactions of the Paris Society, they are cultivating the Jerusalem artichoke for feeding their animals. They make 10,000 lb. to the acre, which they say is three times as much as they generally make of the potatoe. The African Negroes brought over to Georgia a seed which they called benn, and the botanists sesamum. I lately received a bottle of the oil, which was eaten with sallad by various companies. All agree it is equal to the olive oil. A bushel of seed yields three gallons of oil. I propose to cultivate it for my own use at least. The embargo keeping at home our vessels, cargoes and seamen, saves us the necessity of making their capture the cause of immediate war; for, if going to England, France had determined to take them, if to any other place, England was to take them. Till they return to some sense of moral duty, therefore, we keep within ourselves. This gives time. Time may produce peace in Europe; peace in Europe removes all causes of difference, till another European war; and by that time our debt may be paid, our revenues clear, and our strength increased. I salute you with great friendship and respect.
