In consequence of this memorial, the Admiralty were directed by his majesty to provide proper vessels for this purpose. Accordingly, the Endeavour bark, which had been built for the coal-trade, was purchased and fitted out for the southern voyage, and I was honoured with the command of her. The Royal Society, soon after, appointed me, in conjunction with Mr Charles Green the astronomer, to make the requisite observations on the transit. It was at first intended to perform this great, and now a principal business of our voyage, either at the Marquesas, or else at one of those islands which Tasman had called Amsterdam, Rotterdam, and Middleburg, now better known under the name of the Friendly Islands. But while the Endeavour was getting ready for the expedition, Captain Wallis returned from his voyage round the world, in the course of which he had discovered several islands in the South Sea; and, amongst others, Otaheite. This island was preferred to any of those before mentioned, on account of the conveniences it afforded; because its place had been well ascertained, and found to be extremely well suited to our purpose. I was therefore ordered to proceed directly to Otaheite; and after astronomical observations should be completed, to prosecute the design of making discoveries in the South Pacific Ocean, by proceeding to the south as far as the latitude of 40°; then, if I found no land, to proceed to the west between 40° and 35°, till I fell in with New Zealand, which I was to explore; and thence to return to England by such route as I should think proper. In the prosecution of these instructions, I sailed from Deptford the 30th July, 1768; from Plymouth the 26th of August, touched at Madeira, Rio de Janeiro, and Straits Le Maire, and entered the South Pacific Ocean by Cape Horn in January the following year. I endeavoured to make a direct course to Otaheite, and in part succeeded; but I made no discovery till I got within the tropic, where I fell in with Lagoon Island, Two Groups, Bird Island, Chain Island; and on the 13th of April arrived at Otaheite, where I remained three months, during which time the observations on the transit were made. I then left it; discovered and visited the Society Isles and Oheteroa; thence proceeded to the south till I arrived in the latitude of 40° 22', longitude 147° 29' W.; and, on the 6th of October, fell in with the east side of New Zealand. I continued exploring the coast of this country till the 31st of March, 1770, when I quitted it, and proceeded to New Holland; and having surveyed the eastern coast of that vast country, which part had not before been visited, I passed between its northern extremity and New Guinea, landed on the latter, touched at the island of Savu, Batavia, the Cape of Good Hope, and St Helena,[12] and arrived in England on the 12th of July, 1771.
