The clear weather gave Mr Wales an opportunity to get some observations of the sun and moon. Their results reduced to noon, when the latitude was 58° 22' S., gave us 136° 22' E. longitude. Mr Kendal's watch at the same time gave 134° 42'; and that of Mr Arnold the same. This was the first and only time they pointed out the same longitude since we left England. The greatest difference, however, between them, since we left the Cape, had not much exceeded two degrees.
The moderate, and I might almost say, pleasant weather, we had, at times, for the last two or three days, made me wish I had been a few degrees of latitude farther south; and even tempted me to incline our course that way. But we soon had weather which convinced us that we were full far enough; and that the time was approaching, when these seas were not to be navigated without enduring intense cold; which, by the bye, we were pretty well used to. In the afternoon, the serenity of the sky was presently obscured: The wind veered round by the S.W. to W., and blew in hard squalls, attended with thick and heavy showers of hail and snow, which continually covered our decks, sails, and rigging, till five o'clock in the evening of the 15th. At this time, the wind abated, and shifted to S.E.; the sky cleared up; and the evening was so serene and clear, that we could see many leagues round us; the horizon being the only boundary to our sight.
We were now in the latitude of 59° 17' S., longitude 140° 12' E., and had such a large hollow swell from W.S.W., as assured us that we had left no land behind us in that direction. I was also well assured that no land lay to the south on this side 60° of latitude. We had a smart frost during the night, which was curiously illuminated with the southern lights.
At ten o'clock in the morning of the 16th, (which was as soon as the sun appeared,) in the latitude of 58° 51' S., our longitude was 144° 10' E. This good weather was, as usual, of short duration. In the afternoon of this day, we had again thick snow showers; but, at intervals, it was tolerably clear; and, in the evening being in the latitude of 58° 58' S., longitude 144° 37' E., I found the variation by several azimuths to be 31' E.
I was not a little pleased with being able to determine, with so much precision, this point of the Line, in which the compass has no variation. For I look upon half a degree as next to nothing; so that the intersection of the latitude and longitude just mentioned, may be reckoned the point without any sensible error. At any rate, the Line can only pass a very small matter west of it.
I continued to steer to the east, inclining to the south, with a fresh gale at S.W., till five o'clock the next morning, when, being in the latitude of 59° 7' S., longitude 146° 53' E., I bore away N.E., and, at noon, north, having come to a resolution to quit the high southern latitudes, and to proceed to New Zealand to look for the Adventure, and to refresh my people. I had also some thoughts, and even a desire to visit the east coast of Van Diemen's Land, in order to satisfy myself if it joined the coast of New South Wales.
In the night of the 17th, the wind shifted to N.W., and blew in squalls, attended with thick hazy weather and rain. This continued all the 18th, in the evening of which day, being in the latitude of 56° 15' S., longitude 150°, the sky cleared up, and we found the variation by several azimuths to be 13° 30' E. Soon after, we hauled up, with the log, a piece of rock-weed, which was in a state of decay, and covered with barnacles. In the night the southern lights were very bright.
The next morning we saw a seal; and towards noon, some penguins, and more rock-weed, being at this time in the latitude of 55° 1', longitude 152° 1' E. In the latitude of 54° 4', we also saw a Port Egmont hen, and some weed. Navigators have generally looked upon all these to be certain signs of the vicinity of land; I cannot, however, support this opinion. At this time we knew of no land, nor is it even probable that there is any, nearer than New Holland, or Van Diemen's Land, from which we were distant 260 leagues. We had, at the same time, several porpoises playing about us; into one of which Mr Cooper struck a harpoon; but as the ship was running seven knots, it broke its hold, after towing it some minutes, and before we could deaden the ship's way.
As the wind, which continued between the north and the west, would not permit me to touch at Van Diemen's Land, I shaped my course to New Zealand; and, being under no apprehensions of meeting with any danger, I was not backward in carrying sail, as well by night as day, having the advantage of a very strong gale, which was attended with hazy rainy weather, and a very large swell from the W. and W.S.W. We continued to meet with, now and then, a seal, Port Egmont hens, and sea-weed.
On the morning of the 22d, the wind shifted to south, and brought with it fair weather. At noon, we found ourselves in the latitude of 49° 55', longitude 159° 28', having a very large swell out of the S.W. For the three days past, the mercury in the thermometer had risen to 46, and the weather was quite mild. Seven or eight degrees of latitude had made a surprising difference in the temperature of the air, which we felt with an agreeable satisfaction.
