During the three days before making St. Antonio, the wind varied from the regular north-east trade, to east-north-east, and as far as south-east-by-east; and about the time of seeing the land, it dwindled to a calm. For three days afterwards it was light, and variable between north and south-east; after which it sometimes blew from the north-west and south-west, and sometimes from the eastward. These variable winds, with every kind of weather, but most frequently with rain, continued until the 23rd [SUNDAY], in latitude 11° north and longitude 23° west; when a steady breeze set in from the south-westward, and the weather became more settled and pleasant. The clouds were sufficiently dense to keep off the intense heat of the vertical sun, but did not often prevent us from obtaining daily observations for the latitude and longitude. At the same time with the south-west wind came a swell from the southward, which made the ship plunge considerably; and so far opened her leaks, that she again made two inches of water in the hour.
THURSDAY 27 AUGUST 1801
On the 27th, in latitude 6° north and longitude 17½° west, a noddy was caught, and next day a swallow was found dead in my sleeping cabin. This poor little bird had been our companion for three or four days before, and had become a favourite. It was generally seen darting past the lee scuttles and ports, apparently after the flies which were carried out by the streams of air; sometimes it alighted upon the boats which hung on the ship's quarters, and more than once rested itself in the cabin where, at length, it was found dead.
WEDNESDAY 2 SEPTEMBER 1801
The south-western winds continued to blow without intermission, and drove us, much against my inclination, far to the eastward, towards the coast of Africa. One or two attempts were made to go upon the western tack; but this could not be done with any advantage until the 2nd of September, when we were in latitude 3° 50' north, and longitude 11¼° west. The wind had veered gradually round, from south-west to south, as we approached the African coast, to the direction of which it kept at nearly a right angle. I had not fully adverted to the probability, that the winds blowing upon this coast would prevail to a greater extent at this season than at any other time of the year; otherwise, as I wished to avoid Africa, I should have passed some degrees to the westward of the Cape-Verde Islands, and probably have carried the north-east trade to the 12th, or perhaps to the 10th degree of north latitude; and in 8°, or at furthest in 6°, the south-east trade might have been expected.
Captain Cook, in his second voyage, experienced the same south-western winds, and was carried so far eastward, that he crossed the equator in longitude 8° west. Monsieur de la Pérouse also experienced them, and both were here at the same season with ourselves; that is, in the months of August and September, when the African continent had received its greatest degree of heat.
Although I preferred to avoid Africa, it is by no means certain that a good passage to the Cape of Good Hope may not be made, especially at this season, by steering round the Bight of Benin with the south-west and south winds. It is probable, that on approaching the meridian of Greenwich the wind would be found to return to the south-west, and perhaps more westward, and enable a ship to reach the 10th degree of south latitude before meeting the south-east trade; in which case, the circuit to be made before attaining the western winds beyond the southern tropic, would be much shortened. The East-India-Company's ships bound to St. Helena, do, I believe, now generally follow that route.
The leakiness of the ship increased with the continuance of the south-west winds; and at the end of a week, amounted to five inches of water an hour. It seemed, however, that the leaks were mostly above the water's edge, for on tacking to the westward they were diminished to two inches. This working of the oakum out of the seams indicated a degree of weakness which, in a ship destined to encounter every hazard, could not be contemplated without uneasiness. The very large ports, formerly cut in the sides to receive thirty-two-pound carronades, joined to what I had been able to collect from the dock yard officers, had given me an unfavourable opinion of her strength; and this was now but too much confirmed. Should it be asked, why representations were not made, and a stronger vessel procured? I answer, that the exigencies of the navy were such at that time, that I was given to understand no better ship could be spared from the service; and my anxiety to complete the investigation of the coasts of Terra Australis did not admit of refusing the one offered.
THURSDAY 3 SEPTEMBER 1801
The wind was at south when we tacked to the westward; but it shortly veered to south-by-east, and as far as south-east-by-south, which enabled me to look up for the small Isle Sable, or St. Paul, said to lie in 0° 25' south, and about 18½° west. I was desirous of ascertaining the true position of this, and of some other small islands, laid down in the neighbourhood of the equator. They are placed so much in the tracks, both of outward and homeward bound ships, that it was not improbable some one of the vessels missed at different times, might have suffered shipwreck upon them; and the hope that we might be the happy means of restoring to their country and friends some unfortunate fellow creatures, perhaps countrymen, was an additional incitement to look after them.
