About six o’clock in the morning, we anchored in fifteen fathom, the shoal bearing N.N.W.1/2 W. at the distance of about half a mile. At noon, we weighed with a light breeze at N.E. and worked with the ebb tide till two; but finding the water shoal, we anchored again in six fathom and a half, at about the distance of half a mile from the south side of the shoal; the Asses’ Ears then bearing N.W. by W. distant four leagues, and the south point of the entrance of the first Narrow W.S.W. distant about three leagues. At this time the opening of the narrow was shut in, and upon sending out the boats to sound, they discovered a channel between the shoal and the south shore of the streight. The Tamar in the mean time, as she was endeavouring to come near us, was very near going on shore, having once got into three fathom, but soon after came to an anchor in the channel between the shoal and the north shore.
The next morning, about eight o’clock, we weighed, with little wind at W.S.W. and steered about half a mile S.E. by E. when, having deepened our water to thirteen fathom, we steered between the E. and E.N.E. along the south side of the shoal, at the distance of about seven miles from the south shore, keeping two boats at some distance, one on each bow, to sound. The depth of water was very irregular, varying continually between nine and fifteen fathom; and upon hauling nearer to the shoal, we had very soon no more than seven fathom: The boats went over a bank, upon which they had six fathom and a half; it being then low water, but within the bank, they had thirteen fathom. At noon, we were to the eastward of the shoal, and as we hauled over to the north shore, we soon deepened our water to twenty fathom. Point Possession at this time bore N.N.W. distant between four and five leagues, the Asses’ Ears W.N.W. distant six leagues, and Cape Virgin Mary N.E.1/2 E. distant about seven leagues. From this situation we steered N.E. by E. for the south end of the spit which runs to the southward of the Cape, and had no soundings with five and twenty fathom. At four in the afternoon, Cape Virgin Mary bore N.E. and the south end of the spit N.E. by E. distant three leagues. At eight the next morning, the Cape bore N. by W. distant two leagues. Our latitude was 51 deg. 50’, and our soundings were eleven and twelve fathom. We now brought-to for the Tamar, who had come through the north channel, and was some leagues astern of us, and while we were waiting for her coming up, the officer of the watch informed me that the head of the main-mast was sprung: I immediately went up to look at it myself, and found it split almost in a straight line perpendicularly for a considerable length, but I could not discover exactly how far the fissure went, for the cheeks that were upon the mast. We imagined this to have happened in the very hard gale that had overtaken us some time before; but as it was of more importance to contrive how to repair the damage, than discover how it happened, we immediately put on a strong fish, and woolded it so well, that we had reason to hope the mast would be as serviceable as ever. Cape Virgin Mary now bore S. 62 deg. W. distant twenty-one leagues, and our latitude was 51 deg. 50’ S. longitude 69 deg. 56’ W.; the variation 20 deg. E.
