Gardoqui came to America in 1786 as _charge d'affaires_ for the negotiation of a treaty with Spain. The "public character" in which Jaudenes was presented in 1791 was that of commissioner of Spain, and he had united with him on the commission Josef de Viar, all their official documents being signed with both names. Their main business, like Gardoqui's, was the negotiation of a treaty between Spain and the United States; a treaty which was to settle boundaries, rights of trade between the two nations, and also the question of the "occlusion" of the Mississippi River; but there was much outside diplomatic sparring over the disputes between the Governor of Louisiana and the Georgians about trespasses and conflicting rights. The last communication of the commissioners was dated in 1794. The next year the negotiations were transferred to Madrid and the treaty was signed there and Jaudenes probably then returned to Spain. There seems to be no trace of him after that. The only other facts in regard to him are to be gathered from the two pictures recently acquired by the Metropolitan Museum of Art, which are the subject of this article. They are signed G. Stuart, R. A., New York, September 8, 1794, and bear inscriptions in Spanish which, to complete the record, are here given in full: DON JOSEF DE JAUDENES Y NEBOT COMISARIO ORDENADOR DE LOS REALES EXERCITOS Y MINISTRO EMBIADO DE SU MAGESTAD CATHOLICA CERCA DE LOS ESTADOS UNIDOS DE AMERICA.
