Continued standing to the Northward, with a fresh gale at East by South and South-East until 6 o'clock, having very irregular and uncertain soundings from 24 to 7 fathoms. At 4 we made the Land from the Mast head, bearing North-West by North, and which appear'd to be very low. At 6 it extended from West-North-West to North-North-East, distant 4 or 5 Leagues. At this time hauld close upon a wind to the Eastward until 7 o'clock, then Tack'd and stood to the Southward until 12, at which time we wore and stood to the Northward until 4, then lay her Head off until daylight, when we again saw the Land, and stood North-North-West directly for it, having a fresh gale at East by South. Our Soundings in the night were from 17 to 5 fathoms, very irregular, without any sort of Rule with respect to our distance from the Land. At 1/2 past 6 a small low island, laying about a League from the Main, bore North by West, distant 5 miles; this island lays in the Latitude of 8 degrees 13 minutes South, Longitude 221 degrees 25 minutes West. I find it laid down in the Charts by the Name of St. Bartholomew or Whermoysen. We now steer'd North-West by West, West-North-West, West by North, West by South, and South-West by West, as we found the land to lay, having a Boat ahead of the Ship sounding; depth of water from 5 to 9 fathoms. When in 7, 8 or 9 fathoms we could but just see the Land from the Deck; but I did not think we were at above 4 Leagues off, because the land is exceeding low and level, and appeared to be well cover'd with wood; one sort appeared to us to be Cocoa Nutt Trees. By the Smookes we saw in different parts as we run along shore we were assured that the Country is inhabited. At Noon we were about 3 Leagues from the land, the Westermost part of which that we could see bore South 79 degrees West; our Latitude by Observation was 8 degrees 19 minutes South, Longitude 221 degrees 44 minutes West. The Island, St. Bartholomew, bore North 74 degrees East, distant 20.*

* The ship was now off the south coast of New Guinea, and near what is known as Princess Marianne Strait, which separates Frederick Henry Island from the main island. All this coast is very shallow, but very imperfectly charted to the present day.
