At an early date of the revolution commissioners arrived in Washington seeking recognition of independence, and agents were forthwith dispatched to South America to obtain information in regard to the state of the revolutionary governments and to watch the movements of England and other European powers. Joel R. Poinsett was sent to Buenos Aires in 1811, and the following year Alexander Scott was sent to Venezuela.[40] In 1817 Caesar A. Rodney, Theodorick Bland, and John Graham were dispatched as special commissioners to South America. They proceeded to Buenos Aires, where they arrived in February, 1818, and remained until the last of April. Rodney and Graham then returned to the United States while Bland proceeded across the continent to Chile. Their reports were transmitted to Congress November 17, 1818.[41] In 1820 Messrs. J. B. Prevost and John M. Forbes were sent as commercial agents to Chile and Buenos Aires. Reports from them on the state of the revolutions were transmitted to Congress, March 8 and April 26, 1822.[42] In the meantime a strong sentiment in favor of the recognition of South American independence had arisen in the United States. The struggling colonies found a ready champion in Henry Clay, who, for a period of ten years labored almost incessantly in their behalf, pleading for their recognition first with his own countrymen and then, as secretary of state under the Adams administration, with the governments of Europe. His name became a household word in South America and his speeches were translated and read before the patriot armies. In spite of the fact that our own political interests were so closely identified with the struggling republics, the President realized the necessity of following a neutral course, and in view of the aid the colonies were receiving from citizens of the United States, called upon Congress for the enactment of a more stringent neutrality law. Clay delivered a vigorous speech in opposition to this measure in January, 1817. His greatest effort in behalf of South America, however, was his speech of March 25, 1818, on the general appropriation bill. He moved an amendment appropriating $18,000 for the outfit and year's salary of a minister to the United Provinces of the Plate. Without waiting to hear the report of the three commissioners who had been sent to inquire into the state of the revolutionary governments, he urged that a minister be regularly accredited to Buenos Aires at once. In a speech, three hours in length, he concluded the arguments he had begun the day before. Painting with even more than his usual fire and enthusiasm the beauties and resources of the Southern continent, he said:
