Panama. Because the Constitution of Panama required that the president be native-born, a clause allowing Amador to serve based on his service to the independence movement was inserted. During his presidency, he established the gold Balboa as the official currency at par with the U. S. gold dollar. His administration adopted the flag, designed by his son Manuel and sewn by his wife and her sister-in-law, Angélica Bergamonta de la Ossa, and the national anthem, that features lyrics written by his wife's brother Jerónimo de la Ossa; created the national theater and national museum; disbanded the army, in favor of a police force; and expanded the educational system in the country. One of the immediate actions of his administration was to resolve a difference in interpretation over the law which created the canal zone, passed on 28 April 1904. Panamanian legislators intended the granting of the zone to the United States to mean that the U.S. could exercise sovereignty "only for the purpose of building the canal". As the ports were vital for Panama's economy, the government of Panama had no intention of surrendering complete legal or economic sovereignty in the canal zone and did not cede its territory to the U.S. The Americans had established ports, customs houses and postal facilities in the zone, which were objected to by the Panamanians, as they had nothing to do with construction and were functions of a sovereign power. U.S. Minister to Panama Charles Edward Magoon, who was concurrently the Governor of the Canal Zone, worked with Amador to draft a working agreement to resolve the issue. Secretary of War William Howard Taft agreed with the main draft and went to Panama to meet with Amador, arriving on 27 November 1904. The three men devised an agreement to exempt only duty-free goods entering the canal zone ports of Ancon and Cristobal that were related to construction of the canal. Other goods were to be taxed by Panamanian authorities at a reduced rate of ten percent ad valorem. In exchange for infrastructure development with hospitals and roads, Amador was pleased to agree to allow the Canal Company to control sanitation and quarantine provisions in the zone and utilize municipal buildings. They also designated an agreement for currency sharing and postal regulations, among other revisions. The Taft Memorandum would affect U.S.-Panamanian relations for nearly 100 years. Death and legacy Amador decided not to run
