Captain Cook in the South Pacific
The extraordinary achievements of James Cook (1728-1779) on his three voyages in the ships Endeavor, Resolution, Adventure, and Discovery left his successors with little to do but marvel over them. A product of the Age of Enlightenment, Cook was a mathematician, astronomer, practical physician, and master navigator. Son of a Yorkshire laborer, he learned seamanship on small coastal traders plying England's east coast. He joined the British Navy in 1755 and soon made a name for himself in Canada where he surveyed the St. Lawrence River, greatly contributing to the capture of Quebec City in 1759. Later he charted the coast of Newfoundland. Chosen to command the Endeavor in 1768 though only a warrant officer, Cook was the first captain to eliminate scurvy from his crew (with sauerkraut).
The scientists of his time needed accurate observations of the transit of Venus, for if the passage of Venus across the face of the sun were measured from points on opposite sides of the earth, then the size of the solar system could be determined for the first time. In turn, this would make possible accurate predictions of the movements of the planets, vital for navigation at sea. Thus Cook was dispatched to Tahiti, and Father Hell (a Viennese astronomer of Hungarian origin) to Vardo, Norway.
So as not to alarm the French and Spanish, the British admiralty claimed Cook's first voyage (1768-1771) was primarily to take these measurements. His real purpose, however, was to further explore the region, in particular to find terra australis incognita. After three months on Tahiti, he sailed west and spent six months exploring and mapping New Zealand and the whole east coast of Australia, nearly tearing the bottom off his ship, the Endeavor, on the Great Barrier Reef in the process. Nine months after returning to England, Cook embarked on his second expedition (1772-1775), resolving to settle the matter of terra australis incognita conclusively. In the Resolution and Adventure, he sailed entirely around the bottom of the world, becoming the first to cross the Antarctic Circle and return to tell about it.
In 1773 John Harrison won the greater part of a £20,000 reward offered by Queen Anne in 1714 "for such Person or Persons as shall discover the Longitude at Sea." Harrison won it with the first marine chronometer (1759), which accompanied Cook on his second and third voyages. Also on these voyages was Omai, a native of Tahiti who sailed to England with Cook in 1774. Omai immediately became the talk of London, the epitome of the "noble savage," but to those who knew him he was simply a sophisticated man with a culture of his own.
In 1776 Cook set forth from England for a third voyage, supposedly to repatriate Omai but really to find a Northwest Passage from the Pacific to the Atlantic. He rounded the Cape of Good Hope and headed east to New Zealand, Tonga, and Tahiti. He then turned due north, discovering Kauai in what we now know as the Hawaiian Islands on January 18, 1778. After two weeks in Hawaii, Cook continued north via the west coast of North America but was forced back by ice in the Bering Strait. With winter coming, he returned to Hawaiian waters and located the two biggest islands of the group, Maui and Hawaii. On February 14, 1779, in a short, unexpected, petty skirmish with the Hawaiians, Cook was killed. Today he remains the giant of Pacific exploration. He'd dispelled the compelling, centuries-old hypothesis of an unknown continent, and his explorations ushered in the British era in the South Seas.
The Fatal Impact
Most early contacts with Europeans had a hugely disintegrating effect on native cultures. When introduced into the South Pacific, European sicknesses—mere discomforts to the white man—devastated whole populations. Measles, influenza, tuberculosis, dysentery, smallpox, typhus, typhoid, and whooping cough were deadly because the islanders had never developed resistance to them. The white man's alcohol, weapons, and venereal disease further accelerated the process.
