On the 15th the observed latitude at noon, together with the watch, shewed that we had had a strong current setting to the S.W., the contrary direction to what we had experienced on some of the preceding days, as hath been mentioned.[15]
[Footnote 15: It is highly probable, that both these currents were branches of the equinoctial current, that flows from east to west--the first, which was farthest off from land, being on the return towards the east; and the second, which was found nearer to the land, having still enough of its original impulse to direct it onwards by the coast to the southern point of Africa, from which it would afterwards be deflected. Similar circuits are well known to be performed by the equinoctial current, in the Atlantic Ocean, on both sides of the equator.--E.]
At day-light, on the 16th, we saw two sail in the N.W. quarter standing to the westward, and one of them shewing Dutch colours. At ten o'clock we tacked and stood to the west also, being at this time in the latitude of 39° 9' S., longitude 22° 38' E.
I now, in pursuance of my instructions, demanded of the officers and petty officers, the log-books and journals they had kept; which were delivered to me accordingly, and sealed up for the inspection of the Admiralty. I also enjoined them, and the whole crew, not to divulge where we had been, till they had their lordships' permission so to do. In the afternoon, the wind veered to the west, and increased to a hard gale, which was of short duration; for, the next day, it fell, and at noon veered to S.E. At this time we were in the latitude of 34° 49' S., longitude 22° E.; and, on sounding, found fifty-six fathoms water. In the evening we saw the land in the direction of E.N.E. about six leagues distant; and, during the fore-part of the night, there was a great fire or light upon it.
At day-break on the 18th, we saw the land again, bearing N.N.W., six or seven leagues distant, and the depth of water forty-eight fathoms. At nine o'clock, having little or no wind, we hoisted out a boat, and sent on board one of the two ships before-mentioned, which were about two leagues from us; but we were too impatient after news to regard the distance. Soon after, a breeze sprung up at west, with which we stood to the south; and, presently, three sail more appeared in sight to windward, one of which shewed English colours.
