Ireland had also its representatives in South American diplomacy and the making of treaties. As early as 1809 Colonel James Burke was sent by Lord Strangford, British minister at Rio, on a confidential mission to Buenos Ayres to negotiate the establishment of a separate kingdom on the river Plate, with the Princess Charlotte as queen. In 1867 Mr. Gould, an Irishman, British chargé d'affaires, endeavored to mediate between the allies, Brazil and Argentina, and President Lopez of Paraguay, but without success. Stephen H. Sullivan, British chargé d'affaires for Chile, signed the treaty of commerce and navigation between England and Chile on the 10th of May, 1852. He was afterwards appointed British minister at Lima, where he was murdered. The late Chilian ministers to Buenos Ayres and London, William Blest Gana and Albert Blest Gana, were the sons of an Irish Doctor Blest from Sligo, who settled in Chile. In 1859 George Fagan signed a treaty with General Guido for compensation of losses to British subjects during the civil wars after the Independence. The mining industry had among its pioneers brave sons of Erin. J. O. French went to Buenos Ayres in 1826, and after an arduous mountain journey arrived at the foot of the Cerro Morado, where he found auriferous ores. Chevalier Edmond Temple, an Irish gentleman who had served in Spain in a dragoon regiment, also landed in Buenos Ayres in 1826, and started across the Pampas, then almost uninhabited, until he came to the mountainous country where the Potosi mines were situated. In one of the defiles he lost his favorite horse, and in his book he bids a touching farewell to the friendly steed which had shared with him so many toils and dangers. Temple's successor in the Argentine mining provinces was Major Rickard Seaver, a member of an old Co. Dublin family.
