In the afternoon we examined the former, and from a summit at the south-west end of the island in the entrance obtained another set of bearings.

Afterwards we sounded its channel, and found a deep passage, but too narrow and intricate to be preferred to the eastern channel.
Whilst one boat was thus employed, Mr.Baskerville went to examine an opening at the bottom of the port, which he reported to be a strait, trending round to the South-West for six miles, beyond which his view was intercepted by the next projecting point.

The strait, which he called after Captain R.H.Rogers, R.N., is sprinkled with many islands and dry reefs of great extent.

On the 12th I was occupied in laying down the plan of this place, which, on account of the day, was honoured with the name of our most gracious king, Port George the Fourth.

The next day we sailed out by the eastern channel, but having to beat against the wind, made no further progress than an anchorage off Point Adieu, which was the last land seen by us in the Mermaid; it is the north end of the land that forms the west side of Port George the Fourth, which was afterwards called Augustus Island: to the westward of the point there appeared to be many islands and much broken land.

I sent Mr.Roe to Point Adieu to get some bearings from the summit of the hill, and in the meantime Mr.Baskerville sounded the channel between the point and the islands; which he found to be deep and clear; Mr.Roe's report, however, of the appearance of the inner part among the islands was not so favourable, for it is studded over with numerous extensive reefs, which, being low water, were exposed to view.

Mr.Roe saw a tolerably broad separation between two islands to the south-west, but more to the westward the islands were so numerous that very little information as to their shape or number could be obtained.

At daylight the following morning we weighed, and with a moderate land-breeze from South-East, steered to the North-West, and passed round the islands.
