Cook noticed no current of any importance from the 21st January, the day upon which he doubled Cape Horn, to the 1st of March, in a distance of one hundred and sixty leagues of sea. He discovered a good many islands in the Dangerous Archipelago, which he respectively named, Lagoon, Arch, Groups, Birds, and Chain Islands. The greater number were inhabited and were covered with vegetation, which to sailors who for three months had seen only sea and sky, and the frozen rocks of Tierra del Fuego, appeared luxuriant. Soon they found Martea Island, which Wallis had named Osnaburgh, and on the next day, 11th of June, the island of Tahiti was reached. Two days later, the _Endeavour_ cast anchor in Port Matavai, called Port Royal by Wallis, and where that captain had had a struggle with the natives, over whom, however, he had triumphed without much difficulty. Cook, aware of the incidents of his predecessor's stay in this port, wished above all to avoid similar scenes. Moreover, it was essential to the success of his observations that no interruption or distraction should occur. His first care was to read out standing orders to his crew, which they were forbidden under heavy penalties to infringe. He first declared that he intended in every possible way to cultivate friendly relations with the natives, then he selected those who were to buy the needed provisions, and forbade all others to attempt any sort of traffic without special permission. Finally, the men who landed were on no pretext to leave their posts, and if any soldier or workman parted with his arms or implements, not only would the price be deducted from his wages, but he would be punished in proportion to the exigency of the case. In addition to this, to guard the observers from attack, Cook decided on constructing a sort of fort, in which they might be sheltered within gun range of the _Endeavour_. He then landed with Messrs. Banks, Solander, and Green, soon found a favourable spot, and in presence of the natives immediately traced out the extent of land he intended to occupy. One of them, named Owhaw, who had had friendly intercourse with Wallis, was particularly profuse in his protestations of friendship. As soon as the plan of the fort was fixed, Cook left thirteen men and an officer in charge of the tents, and accompanied his associates into the interior of the island. But he was speedily recalled by the sound of firing. A very painful incident, the consequences of which might have been serious, had occasioned this. One of the natives had surprised a sentinel near the tents, and had possessed himself of his gun. A general discharge was immediately directed upon the inoffensive crowd, but fortunately no one was injured. The robber meantime was pursued and killed.
