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 deg. 2', and longitude 118 deg. 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 deg. 39', longitude 116 deg. 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. The Prata shoal is of a considerable extent, being six leagues from north to south, and stretching three or four leagues to the eastward of the island; its limit to the westward we were not in a situation to determine. The northeast extremity we place in latitude 20 deg. 58', and longitude 117 deg.; and the south-west in latitude 20 deg. 45', and longitude 116 deg. 44'. For the remaining part of the day we carried a press of sail, and kept the wind, which was N.E. by N., in order to secure our passage to Macao. It was fortunate, that toward evening the wind favoured us, by changing two points more to the east; for had the wind and weather continued the same as during the preceding week, I doubt whether we could have fetched that port, in which case, we must have borne away for Batavia; a place we all dreaded exceedingly, from the sad havoc the unhealthiness of the climate had made in the crews of the former ships that had been out on discovery, and had touched there.
