Befitting a lush, tropical island stranded in the middle of the ocean, Madeira's origins are shrouded in mystery and fanciful legend. Some claim that the archipelago is what remains of Plato's lost Atlantis, or part of a landmass that once fused the continents of Europe and America. The Portuguese Step Ashore: Recorded history of the volcanic archipelago begins in relatively recent times: 1418, just as the golden age of Portuguese discovery was erupting. Under the leadership of Henry the Navigator, caravels set out from the westernmost point of the Algarve, in southern Portugal, in search of foreign lands, fame, and wealth. Joao Goncalves Zarco, sailing in the service of Prince Henry, made the first of many famous Portuguese discoveries, which would culminate a century later in Magellan's historic circumnavigation of the globe. Zarco happened upon a small volcanic archipelago 1,000 km from Lisbon. Perhaps Zarco knew precisely where he was heading, having learned of the existence of Madeira from a Castilian source. After all, the waters of the Canary Islands, only 445 km (275 miles) to the south, had occupied busy shipping lanes for very nearly a century, and Genovese maps from the mid-14th century depict both Madeira and Porto Santo. More likely, Zarco was heading for Guinea and storms forced him onto the beach of Porto Santo. If so, then he was extremely fortunate, for he managed to land on the only large, sandy beach for hundreds of miles around. Little wonder he subsequently named it Porto Santo (Holy Port). The following year Zarco returned to claim the larger island he had seen from Porto Santo, and with him went Tristao Vaz Teixeira and Bartolomeu Perestrelo. They officially became the first men to set foot on the heavily forested island, naming it Ilha da Madeira, "Island of Timber. " The Portuguese Crown, delighted with its first important discovery, immediately embarked on a program of colonization. Zarco and Teixeira were appointed co-governors of Madeira, while Perestrelo was awarded Porto Santo. <sep>When Zarco first landed on the volcanic archipelago, had he landed on what he later named "Madeira"?<sep>The beach of Porto Santo

The National Security Act of 1947 created the position of Director of Central Intelligence (DCI). Independent from the departments of Defense, State, Justice, and other policy departments, the DCI heads the U.S.intelligence community and provides intelligence to federal entities. The sole element of the intelligence community independent from a cabinet agency is the CIA. As an independent agency, it collects, analyzes, and disseminates intelligence from all sources. The CIA's number one customer is the president of the United States, who also has the authority to direct it to conduct covert operations. Although covert actions represent a very small fraction of the Agency's entire budget, these operations have at times been controversial and over time have dominated the public's perception of the CIA. The DCI is confirmed by the Senate but is not technically a member of the president's cabinet. The director's power under federal law over the loose, confederated "intelligence community" is limited. He or she states the community's priorities and coordinates development of intelligence agency budget requests for submission to Congress. This responsibility gives many the false impression that the DCI has line authority over the heads of these agencies and has the power to shift resources within these budgets as the need arises. Neither is true. In fact, the DCI's real authority has been directly proportional to his personal closeness to the president, which has waxed and waned over the years, and to others in government, especially the secretary of defense. Intelligence agencies under the Department of Defense account for approximately 80 percent of all U.S. spending for intelligence, including some that supports a national customer base and some that supports specific Defense Department or military service needs. As they are housed in the Defense Department, these agencies are keenly attentive to the military's strategic and tactical requirements. <sep>Which independent agency collects, analyzes, and disseminates intelligence from all sources?<sep>CIA

I've been thinking about the mindwipe, now two days away. Who said that those who forget the past are doomed to repeat it? I fear that may be true for me. Add this to the reasons I write now: to remember something, perhaps even to learn -- Emil Malaquez arrived after sundown, carrying a small package wrapped in what looked like real paper. His evening dress was formal, expensive, and slightly stained, as that of all forgetful artists should be. He was a jovial man with an easy laugh, and even uglier than Tasha had suggested. I liked him immediately. "Senor Malaquez?" "Please. Call me Emil. You must be Bernardo. Tasha's told me much about you." "All of it outrageous praise?" "All of it." "Ah, she is wonderfully perceptive." He raised an eyebrow, then guffawed. "Has she said as much about me?" "She thinks you are a genius. Do come in." "Thank you." <sep>Could it be said that Mr. Malaquez has a mutual respect for Bernardo?<sep>Yes, the invitation to "come in" suggests he at least likes him enough to continue their appointment, and their mutual friend Tasha seems to have spoken highly of Bernardo to Malaquez
