Tupia informs us that in the Months of November, December, and January they have constant Westerly winds, with rain; also that the whole island can muster 6780 Fighting Men, by which some judgment can be formed of the number of inhabitants. Each district furnishes a certain number, which the chief is obliged to bring into the field when summoned by the Eare dehi, or King of the Island, either to make war or repell an invasion.* (* This paragraph is added in Admiralty copy.) [Historical Notes, Tahiti.] Notes on Tahiti. The missionaries who came to Tahiti in 1797, in the missionary ship Duff, and settled at Matavai, gathered many details of the history and economy of the islands. It appears that the state of society, though in many respects savage, had attained a certain pitch of civilisation, especially with regard to government. There was generally a head chief or king of the whole island, who governed after the feudal manner by the sub-chiefs. The sovereignty was hereditary, with this peculiarity, that the eldest son of the king became from his birth the sovereign. The father governed henceforth as regent until the son was of an age to take the reins in his own hands, when the father retired. This was the idea; but, as may be imagined, it led to various complications and difficulties, and wars between the different parts of the island and the different chiefs were frequent. When Wallis discovered the island, in June 1767, Amo was king, or Arii-rahi (called by Cook Eare-dehi), Bereia (Cook's Obereia) being his wife. The latter seems to have been a woman of much character, and to have practically governed the island. The two were separated, inasmuch that they had mutually contracted other alliances, but, according to the custom of the country, without affecting their friendship. On Wallis's appearance the warlike Tahitians at once attacked the Dolphin, but were easily defeated, and the guns and small arms with which they then for the first time made acquaintance had such an effect upon them that they speedily made peace, and recognised the superiority of Europeans. The defeat had, however, a great effect on the prestige of Amo, whose authority rapidly diminished. Tootaha, Amo's brother, and chief of the district of Matavai, where the Dolphin anchored, was much enriched by her visit, and became a greater man in the eyes of his compatriots. Bougainville also touched at Tootaha's district; and although his two ships only remained ten days, it was long enough to furnish this chief with many more valuable and coveted articles.
