At midnight between the 16th and 17th of August breakers were discovered ahead and upon our bow, and not a mile from us. We were lying to and heaving the lead at the time and had no ground at 120 fathoms. We wore the ship and stood from them and in less than an hour after more breakers were seen extending more than a point before our lee beam, but we made more sail and so got clear of them all. At daylight we put about with the intention of examining the breakers we had seen in the night and we made two boards, but perceiving that I could not weather them without some risk I bore up and ran round its N.W. end. It is a double reef enclosing a space of deeper water like the lagoon islands so common in these seas, and probably will become one in the course of time. The sea breaks pretty high upon it in different parts, but there is no part of the reef absolutely above water. It is about seven miles long in the direction of N.W. by N. Its breadth is not so much. Called it Willis's shoal. It lies in Latitude 12 deg. 20' S. and Longitude 200 deg. 2' W.[69-1] We pursued our course to the Westward and on the 23rd saw the land bearing from N.E. to N. by W. The Easternmost land when first seen was ten or twelve leagues from us and it cannot be far to the Westward of the land seen by Mons. Bougainville and called by him Louisiade, and probably joins to it. The cape is in Latitude 10 deg. 3' 32" S. and Longitude 212 deg. 14' W., was called Cape Rodney and another cape in Latitude 9 deg. 58' S. and Longitude 212 deg. 37' W. was called Cape Hood, and an island lying between them was called Mount Clarence. After passing Cape Hood the land appears lower and to branch off about N.N.W. and to form a deep and wide bay, or perhaps a passage through, for we saw no other land, and there are doubts whether it joins New Guinea or not.[69-2] I pursued my course to the Westward between the Latitudes of 10 deg. and 9 deg. 33' S. keeping the mouth of Endeavour Straits open, by which I hoped to avoid the difficulties and dangers experienced by Captain Cook in his passage through the reef in a higher latitude, and also the difficulties he met with when within in his run from thence to the Strait's mouth.[70-1] On the 25th August at 9 in the morning, saw breakers from the mast head bearing from us W. by S. to W.N.W. I hauled up to the Southward and passed to the Eastward of them. It runs in the direction of W.S.W. and E.N.E. 4' or 5', and another side runs in the direction of N.W. the distance unknown. The sea broke very moderately upon it, in some places barely perceptibly. In the interior part a very small sand-bank was seen from the mast-head, and no other part of the reef was above water. It obtained the name of Look-Out shoal.[70-2]
