Before noon we saw more breakers which proved to be one of those half-formed islands enclosing a lagoon, the reef of which was composed principally of very large stones, but a sandbank was seen from the mast head extending to the Southward of it, and as I could not weather it and seeing another opening to the Westward, I steered to the W.S.W., and a little before two o'clock saw the island to the Westward of us, and another reef bearing about S.W. by South and I then steered W. 1/2 N. until half past five, when a reef was seen extending from the island a considerable way to the N.W., the island bearing then about W.S.W. I immediately hauled upon the wind in order to pass to the Southward of it, and seeing a passage to the Northward obstructed[71-1] I stood on and off, and was still during the night, and in the morning bore away; but as we drew near we also saw a reef extending to the Southward from the South end of the island. I ran to the Southward along the reef with the intention and expectation of getting round it, and the whole day was spent without succeeding in my purpose and without seeing the end of the reef, or any break in it that gave the least hopes of a channel fit for a ship.[71-2] The islands, which I called Murray's Islands, are four in number, two of them are of considerable height and may be seen twelve leagues. The principal island is not more than three miles long. It is well wooded and at the top of the highest hill the rocks have the appearance of a fortified garrison. The other high island is only a single mountain almost destitute of trees and verdure. The other two are only crazy barren rocks. We saw three two mast boats under sail near the reef, which we supposed belong to the islands. Murray Islands lie in Latitude 9 deg. 57' S. and Longitude 216 deg. 43' W. We kept turning to the Southward along the reef until the 28th in search of a channel and in the forenoon of that day we thought we saw an opening through the reef near a white sandy island or key, and a little before Lt. Corner was sent in the yawl to examine it. At three quarters past four he made the signal that there was a channel through the reef fit for a ship, and after a signal was made and repeated for the boat to return on board, and after dark false fires and muskets were fired from the ship, and answered with muskets by the boat repeatedly to point out the situation of each other. We sounded frequently but had no ground at 110 fathoms.
