April 8.
By daylight on the 8th, the boats had left the ship, and were standing to the southward among the islands. Our party consisted of Mr. Helpman, Mr. Fitzmaurice and myself. Passing through the eastern part of Port George the Fourth, we entered Roger Strait, which led into a large sheet of water, forming a beautiful harbour; we landed to obtain a better view of it, on a small island at the southern entrance of this strait. This islet looked truly inviting, being clothed with long rich grass, which to our cost we found concealed boulders of granite; this was the first time we met with this primitive rock, and from the colour of the surrounding heights it was evident we were in an old red sandstone region. Strange to say the attraction on this island rendered our compasses quite useless; we noticed on its North-West side a portion of the wreck of a small vessel. There was a small mangrove inlet in the South-East corner of this harbour, over which the land was low, forming a gap in the neighbouring heights. We now pushed on for an island lying in the entrance of the harbour, bearing West by North 6 miles; our soundings in passing over this part (of what we afterwards called Brecknock Harbour, as Captain King had named the entrance of it Camden Sound, from a distant view he had of it) gave a depth of 7 fathoms, over an even muddy bottom; but towards and in the entrance it increased to 13 fathoms.
ENTRANCE ISLE.
The island we now landed on, we called from its situation, Entrance Island. From a high part overlooking its steep southern side we had a very commanding view. The centre of a string of small islets bore north one mile; there extended 2 miles in a west direction, from the north point of the harbour; both these and Entrance Isle escaped Captain King's notice, owing to the distant view he had of this part of the coast. A point bearing South-West distant 3 miles, was the extreme of the mainland that we could see in the direction we were going. We found the sandstone of this Island not of the same ancient red colour as that on the shore fronting it. One boat was employed in the meantime sounding the entrance of the harbour, which we found to be 2 miles across, and from 9 to 15 fathoms deep; the mouth of it faces the West-North-West, Entrance Isle lying half a mile outside its points, with a clear channel nearly a mile wide, on either side of it.
About a quarter of a mile off the main, and fronting the south side of this island, there is a singular needle-shaped rock, 20 feet high, marking the outer extreme of a coral ledge, which is covered at high-water. As it now blew a fresh breeze from seaward, and the afternoon was far advanced, we spent the remainder of the day in a further examination of the entrance. We were much pleased with the result of our evening's work, finding the approach to this fine harbour quite free from danger, and capable of admitting vessels of any size; there were no reefs or islets seaward of it to add to the anxiety of the navigator, or lessen the value of our discovery; the importance of which will be greatly enhanced, should Lieutenants Grey and Lushington have the good fortune to discover any land fit for colonization in its neighbourhood. Our labours here closed with observations for a boat rate, for the chronometers and latitude, the latter being 15 degrees 27 1/4 minutes South on a sandy beach at the eastern side of Entrance Isle.
SLATE ISLANDS.
April 9.
We rounded the extreme point to the South-West seen from Entrance Isle at sunrise; the rocks on this point were arranged quite in the form of a fort, from whence it received the name of Battery Point; another group of islands now came in view, bearing from Battery Point South-West by South about 4 miles; these we named Slate Islands, from their singular formation. They extended one mile North-West from a point of land; between them and Battery Point, the coast fell back forming two bays, crossing the mouths of which we had 13 fathoms. On passing Slate Islands, we saw a headland, named by Captain King Point Hall, bearing South by West 1/2 West distant 8 miles. It has a high peaked and isolated appearance, being separated from the contiguous high land by a low neck. We passed a bay 2 miles wide on its north-eastern, and a snug cove on its south-eastern side. It was past noon and we were glad to see the stagnant calm, that had for hours reigned around, dispelled by the seabreeze which now darkened the horizon. Our course, during the afternoon was South by East along a low rocky coast, but as we had to contend with a three-knot tide, we did not get farther than a small sandy cove, bearing South by East 9 miles from Point Hall, by the close of the day, which was the only spot we had seen the whole of the afternoon capable of affording shelter for the boats.
FRESHWATER COVE.
We were agreeably surprised to find a stream of water running into the head of this cove, as the parched appearance of the low hills over it did not lead us to expect such good luck, in remembrance of which we called it Freshwater Cove. Landing, I hastened to the south point of the cove, to secure the necessary data for the chart, before the surrounding objects were veiled in darkness. We again appeared to be in a sterile white sandstone region, where, with the exception of a few land birds, there was a total absence of animal life, and almost that of the vegetable, for even the gumtrees common in this part, were not to be seen. Our view to the southward was very limited, embracing only the Montgomery Islands of Captain King; they consist of six small rocky islets resting on an extensive coral flat, that we afterwards observed to be dry at low-water, and which extended to a large low sandy island, lying six miles west from them; the latter was not seen by Captain King, in his distant view of this neighbourhood. The eastern and largest of the Montgomery Isles stands on the extreme of the coral flat; we found it to be 70 feet high, and bore South-West by South 7 miles from this point of Freshwater Cove. The latitude we obtained in the course of the night gave a result of 15 degrees 49 minutes south.
