When researches of this kind, no longer left to the solicitations of an individual, or to the subscriptions of private adventurers, became cherished by the Royal attention, in the present reign, and warmly promoted by the Minister at the head of the naval department, it was impossible, while so much was done toward exploring the remotest corners of the southern hemisphere, that the northern passage should not be attempted. Accordingly, while Captain Cook was prosecuting his voyage toward the south pole, in 1773, Lord Mulgrave sailed with two ships, _to determine how far navigation was practicable toward the north pole_. And though his Lordship met with the same insuperable bar to his progress, which former navigators had experienced[38], the hopes of opening a communication between the Pacific and Atlantic Oceans, by a northerly course, were not abandoned; and a voyage for that purpose was ordered to be undertaken. The operations proposed to be pursued were so new, so extensive, and so various, that the skill and experience of Captain Cook, it was thought, would be requisite to conduct them. Without being liable to any charge of want of zeal for the public service, he might have passed the rest of his days in the command to which he had been appointed in Greenwich Hospital, there to enjoy the fame he had dearly earned in two circumnavigations of the world. But he cheerfully relinquished this honourable station at home; and, happy that the Earl of Sandwich had not cast his eye upon any other commander, engaged in the conduct of the expedition, the history of which is presented to the public in these volumes; an expedition that would expose him to the toils and perils of a third circumnavigation, by a track hitherto unattempted. Every former navigator round the globe had made his passage home to Europe by the Cape of Good Hope; the arduous task was now assigned to Captain Cook, of attempting it, by reaching the high northern latitudes between Asia and America. So that the usual plan of discovery was reversed; and, instead of a passage from the Atlantic to the Pacific, one from the latter into the former was to be tried. For it was wisely foreseen, that whatever openings or inlets there might be on the east side of America, which lie in a direction which could give any hopes of a passage, the ultimate success of it would still depend upon there being an open sea between the west side of that continent, and the extremities of Asia. Captain Cook, therefore, was ordered to proceed into the Pacific Ocean, through the chain of his new islands in the southern tropic, and having crossed the equator into its northern parts, then to hold such a course as might probably fix many interesting points in geography, and produce intermediate discoveries, in his progress northward to the principal scene of his operations.
