Captain Wickham and Lieutenant Eden in the gig, and myself, accompanied by Mr. Tarrant, in one of the whaleboats; we reached the mangrove isles at sunset, and spent the night between them and the eastern shore. On the 8th the tide suited us but badly, and we were only able to proceed about four miles beyond Escape Point, where we secured the boats in a creek out of the influence of the tide. We found much less water off Escape Point than on our former visit. EXCURSION INTO THE INTERIOR.
