The uses of copper in art were not limited to currency: it was used by Renaissance sculptors, in photographic technology known as the daguerreotype, and the Statue of Liberty. Copper plating and copper sheathing for ships' hulls was widespread; the ships of Christopher Columbus were among the earliest to have this feature. The Norddeutsche Affinerie in Hamburg was the first modern electroplating plant starting its production in 1876. The German scientist Gottfried Osann invented powder metallurgy in 1830 while determining the metal's atomic mass; around then it was discovered that the amount and type of alloying element (e.g., tin) to copper would affect bell tones. Flash smelting was developed by Outokumpu in Finland and first applied at Harjavalta in 1949; the energy-efficient process accounts for 50% of the world's primary copper production.

The country currency is the Samoan tala, issued and regulated by the Central Bank of Samoa. The economy of Samoa has traditionally been dependent on agriculture and fishing at the local level. In modern times, development aid, private family remittances from overseas, and agricultural exports have become key factors in the nation's economy. Agriculture employs two-thirds of the labour force, and furnishes 90% of exports, featuring coconut cream, coconut oil, noni (juice of the nonu fruit, as it is known in Samoan), and copra.

The success of the British Commandos during World War II prompted U.S. President Franklin D. Roosevelt to authorize the creation of an intelligence service modeled after the British Secret Intelligence Service (MI6), and Special Operations Executive. This led to the creation of the Office of Strategic Services (OSS). On September 20, 1945, shortly after the end of World War II, Harry S. Truman signed an executive order dissolving the OSS, and by October 1945 its functions had been divided between the Departments of State and War. The division lasted only a few months. The first public mention of the "Central Intelligence Agency" appeared on a command-restructuring proposal presented by Jim Forrestal and Arthur Radford to the U.S. Senate Military Affairs Committee at the end of 1945. Despite opposition from the military establishment, the United States Department of State and the Federal Bureau of Investigation (FBI), Truman established the National Intelligence Authority in January 1946, which was the direct predecessor of the CIA. Its operational extension was known as the Central Intelligence Group (CIG)

Ah, so..
