Tanna; but by reckoning at the rate it was going when last at Queen Charlotte’s Sound, and from the time of our leaving it, to our return to it again, which was near a year, the error was 19ʹ 31ʺ, 25 in time, or 4° 52ʹ 48ʺ 3/4 in longitude. This error cannot be thought great, if we consider the length of time, and that we had gone over a space equal to upwards of three-fourths of the equatorial circumference of the earth, and through all the climates and latitudes from 9° to 71°. Mr. Wales found its rate of going here to be that of gaining 12ʺ, 576, on mean time, per day. The mean result of all the observations he made for ascertaining the variation of the compass and the dip of the south end of the needle, the three several times we had been here, gave 14° 9ʹ 1/5 E. for the former, and 64° 36ʺ 2/3 for the latter. He also found, from very accurate observations, that the time of high-water preceded the moon’s southing, on the full and change days, by three hours; and that the greatest rise and fall of the water was five feet ten inches and a half; but there were evident tokens on the beach of its having risen two feet higher than it ever did in the course of his experiments. BOOK IV. FROM LEAVING NEW ZEALAND TO OUR RETURN TO ENGLAND. CHAP. I. THE RUN FROM NEW ZEALAND TO TERRA DEL FUEGO, WITH THE RANGE FROM CAPE DESEADA TO CHRISTMAS SOUND, AND DESCRIPTION OF THAT PART OF THE COAST. At daybreak on the 10th, with a fine breeze at W. N. W., we weighed and stood out of the Sound; and, after getting round the Two Brothers, steered for Cape Campbell, which is at the S. W. entrance of the Strait, all sails set, with a fine breeze at north. At four in the afternoon, we passed the Cape, at the distance of four or five leagues, and then steered S. S. E. 1/2 E. with the wind at N. W. a gentle gale, and cloudy weather. Next morning, the wind veered round by the west to south, and forced us more to the east than I intended. At seven o’clock in the evening, the snowy mountains bore W. by S., and Cape Palliser N. 1/2 W. distant sixteen or seventeen leagues; from which Cape I for the third time took my departure. After a few hours’ calm, a breeze springing up at north, we steered S. by E. all sails set, with a view of getting into the latitude of 54° or 55°; my intention being to cross this vast ocean nearly in these parallels, and so as to pass over those parts which were left unexplored the preceding summer. In the morning of the 12th, the wind increased to a fine gale: at noon we observed in latitude 43° 13ʹ 30ʺ S., longitude 176° 41ʹ E., an extraordinary fish of the whale kind was seen, which some called a sea-monster. I did not see it myself. In the afternoon, our old companions the pintado peterels began to appear.
