Every thing being in readiness to put to sea, at sunrise, on the 13th of September, we weighed, and with a fine gale at E. by S., stood out for the same channel we came in by. At half past seven we were in the middle of it. Observatory Isle bore S. 5° E., distant four miles, and the Isle of Balabea W. N. W. As soon as we were clear of the reef, we hauled the wind on the starboard tack, with a view of plying in to the S. E.; but as Mr. Gilbert was of opinion that he had seen the end or N. W. extremity of the land, and that it would be easier to get round by the N. W., I gave over plying, and bore up along the outside of the reef, steering N. N. W., N. W., and N. W. by W. as it trended. At noon the island of Balabea bore S. by W., distant thirteen miles; and what we judged to be the west end of the great land, bore S. W. 1/2 S., and the direction of the reef was N. W. by W., latitude observed 19° 53ʹ 20ʺ. Longitude from Observatory Isle 14ʹ W. We continued to steer N. W. by W. along the outside of the reef till three o’clock, at which time the Isle of Balabea bore S. by E. 1/2 E. In this direction we observed a partition in the reef, which we judged to be a channel, by the strong tide which set out of it. From this place the reef inclined to the north, for three or four leagues, and then to N. W. We followed its direction, and as we advanced to N. W., raised more land, which seemed to be connected with what we had seen before; so that Mr. Gilbert was mistaken, and did not see the extremity of the coast. At five o’clock this land bore W. by N. 1/2 N., distant twenty miles; but what we could see of the reef trended in the direction of N. W. by N.
