This island is about five miles long, in a N.N.E., and S.S.W. direction. The south point is a high barren hill, flattish at the top, and, when seen from the W.S.W., presents an evident volcanic crater. The earth, rock, or sand, for it was not easy to distinguish of which its surface was composed, exhibited various colours, and a considerable part we conjectured to be sulphur, both from its appearance to the eye, and the strong sulphurous smell which we perceived as we approached the point. Some of the officers on board the Resolution, which passed nearer the land, thought they saw steams rising from the top of the hill. From these circumstances, Captain Gore gave it the name of Sulphur Island. A low, narrow neck of land connects this hill with the south end of the island, which spreads out into a circumference of three or four leagues, and is of a moderate height. The part near the isthmus has some bushes on it, and has a green appearance, but those to the N.E. are very barren, and full of large detached rocks, many of which were exceedingly white. Very dangerous breakers extend two miles and a half to the east, and two miles to the west, off the middle part of the island, on which the sea broke with great violence.
The north and south islands appeared to us as single mountains of a considerable height; the former peaked, and of a conical shape; the latter more square and flat at the top. Sulphur Island we place in latitude 24° 48', longitude 141° 12'. The north island in latitude 25° 14', longitude 141° 10'. The south island in latitude 24° 22', and longitude 141° 26'. The variation observed was 3° 30' E.
Captain Gore now directed his course to the W.S.W., for the Bashee Islands, hoping to procure, at them, such a supply of refreshments as would help to shorten his stay in Macao. These islands were visited by Dampier, who gives a very favourable account, both of the civility of the inhabitants, and of the plenty of hogs and vegetables, with, which the country abounds; they were afterwards seen by Byron and Wallis, who passed them without landing.
In order to extend our view, in the day-time, the ships spread between two and three leagues from each other, and during the night, we went under an easy sail; so that it was scarcely possible to pass any land that lay in the neighbourhood of our course. In this manner we proceeded, without any occurrence worth remarking, with a fresh breeze from the N.E., till the 22d, when it increased to a strong gale, with violent squalls of wind and rain, which brought us under close-reefed top-sails.
At noon of the 23d, the latitude, by account, was 21° 5', and longitude 123° 20'; at six in the evening, being now only twenty-one leagues from the Bashee Islands, according to the situation in Mr Dalrymple's map, and the weather squally attended with a thick haze, we hauled our wind to the N.N.W., and handed the fore top-sail.
During the whole of the 24th it rained incessantly, and the wind still blew a storm; a heavy sea rolled down on us from the north, and in the afternoon we had violent flashes of lightning from the same quarter. We continued upon a wind to the N.N.W. till nine o'clock, when we tacked, and stood to the S.S.E., till four in the morning of the 25th, and then wore. During the night there was an eclipse of the moon, but the rain prevented our making any observation; unfortunately, at the time of the greatest darkness, a seaman, in stowing the main-top-mast stay-sail, fell overboard, but laying hold of a rope, which providentially was hanging out of the fore-chains into the water, and the ship being quickly brought in the wind, he was got on board without any other hurt than a slight bruise on his shoulder. At eight, the weather clearing, we bore away but the wind blew still so strong, that we carried no other sail than the fore-sail, and the main-top- sail close-reefed. About this time we saw a land-bird resembling a thrush, and a sugar-cane; at noon, the latitude, by observation, was 21° 35', and longitude 121° 35'.
As our situation in longitude was now to the west of the Bashee, according to Mr Dalrymple's map, I perceived that Captain Gore was governed, in the course he was steering, by the opinions of Commodore Byron and Captain Wallis, with whom he sailed when they passed these islands. The former placing it near four degrees to the westward, or in longitude 118° 15'. In consequence of this opinion, at two, we stood to the southward, with a view of getting into the same parallel of latitude with the islands, before we ran down our longitude. At six, we were nearly in that situation, and consequently ought to have been in sight of land, according to Mr Wallis's account, who places the Bashees near three degrees more to the eastward than Mr Byron. The gale, at this time, had not in the least abated; and Captain Gore, still conceiving that the islands must undoubtedly lie to the westward, brought the ships to, with their heads to the N.W., under the fore-sail and balanced mizen.
At six in the morning of the 26th, the wind having considerably abated, we bore away west; set the top-sails, and let out the reefs. At noon, the latitude, by observation, was 21° 12', and longitude 120° 25'. We saw, this day, a flock of ducks, and many tropic-birds, also dolphins and porpoises, and still continued to pass several pumice-stones. We spent the night upon our tacks, and, at six in the morning of the 27th, again bore away west in search of the Bashees.
I now began to be a little apprehensive, lest, in searching for those islands, we should get so much to the southward as to be obliged to pass to leeward of the Pratas. In this case, it might have been exceedingly difficult for such bad-sailing ships as ours to fetch Macao, particularly should the wind continue to blow, as it now did, from the N.N.E. and N. As I had some doubts whether Mr Dalrymple's charts were on board the Resolution, I made sail and hailed her; and having acquainted Captain Gore with the position of these shoals, and my apprehensions of being driven to the southward, he informed me that he should continue on his course for the day, as he was still in hopes of finding Admiral Byron's longitude right; and therefore ordered me to spread a few miles to the south.
At noon, the weather became hazy; the latitude, by reckoning, was 21° 2', and longitude 118° 30'; and at six, having got to the westward of the Bashees, by Mr Byron's account, Captain Gore hauled his wind to the N.W., under an easy sail, the wind blowing very strong, and there being every appearance of a dirty boisterous night. At four in the morning of the 28th, we saw the Resolution, then half a mile ahead of us, wear, and immediately perceived breakers close under our lee. At day-light, we saw the island of Prata; and at half past six we wore again, and stood toward the shoal, and finding we could not weather it, bore away, and ran to leeward. As we passed the south side, within a mile of the reef, we observed two remarkable patches on the edge of the breakers, that looked like wrecks. At noon, the latitude, found by double altitudes, was 20° 39', longitude 116° 45'. The island bore N. 3/4 E., distant three or four leagues. On the south-west side of the reef, and near the south end of the island, we thought we saw, from the mast-head, openings in the reef, which promised safe anchorage.
