At noon, we were saluted by a Swedish ship, as she passed us, on her way to Europe. At four, the Ladrone bore E., distant two leagues. We now steered S. 1/2 E., with a fresh breeze from the E.N.E., without any occurrence worth remarking, till noon of the 15th, when, being in latitude 18 deg. 57', and longitude 114 deg. 13', the wind veering to the N., we directed our course half a point more to the eastward, in order to strike soundings over the Macclesfield Bank. This we effected at eight in the evening of the 16th, and found the depth of water to be fifty fathoms, over a bottom of white sand and shells. This part of the Macclesfield shoals we placed in latitude 15 deg. 51', and in longitude 114 deg. 20'; which agrees very exactly with the position given in Mr Dalrymple's map, whose general accuracy, if it stood in need of any support, was confirmed, in this instance, by a great number of lunar observations, which we had an opportunity of making every day since we left the Typa. The variation was found to be, in the forenoon, 0 deg. 39' W. On the 17th, we had heavy gales from the E. by N., with a rough tumbling sea, and the weather overcast and boisterous. On the 18th, the wind still continuing to blow strong, and the sea to run high, we altered our course to S.W. by S.; and at noon, being in latitude 12 deg. 34', longitude 112 deg., we began to steer a point more to the westward for Pulo Sapata, which we saw on the 19th, at four in the afternoon, bearing N.W. by W., about four leagues distant. This small, high, barren island, is called _Sapata_, from its resemblance of a shoe. Our observations, compared with Mr Bayley's time-keeper, place it in latitude 10 deg. 4' N. longitude 109 deg. 10' E. The gale had, at this time, increased with such violence, and the sea ran so high, as to oblige us to close-reef the topsails. During the last three days, the ships had outrun their reckoning at the rate of twenty miles a-day, and as we could not attribute the whole of this to the effects of a following sea, we imputed it in part to a current, which, according to my own calculations, had set forty-two miles to the S.S.W., between the noon of the 19th and the noon of the 20th; and is taken into the account in determining the situation of the island.
