As the night wore on the sea rapidly became higher and more dangerous, our difficulties and embarrassments increasing in proportion.  Our chief difficulty arose from the necessity to keep the gig in tow, for with the rising of the sea this speedily became more dangerous to both boats, from the frequent fierce tugs of the painter that connected the two boats together.  The rope was a new and stout one, and there was not much fear that the boats would break away from each other, but the strain set up by the alternate slackening and tautening of the painter, as first one boat and then the other was urged forward by the 'scend of the sea, was tremendous, and strained both craft to a positively dangerous degree.  Yet it was not possible for us to cast the gig adrift, for, had we done so, we should at once have run away from and lost her in the darkness; that is, unless she had set her own sails, and this, of course, could not have been done without depriving her of the protection of them as a covering against the breaking seas, which would have resulted in her being instantly swamped.  But at length matters became so serious with us both that it was evident that something must be done, and that very quickly too; for some of the drags were so violent that they threatened to tear the stern out of the longboat, which was by this time leaking badly.  After considering the matter, therefore, most carefully, I decided upon a course of procedure that I hoped might better our condition somewhat.  It happened that among the stores which we had hurriedly stowed away in the longboat when preparing to leave the schooner was a drum of lamp oil, which we intended to use in our binnacle lamps at night, and which we thought might perhaps also prove very useful for other purposes as well, and this I now ordered the men to find for me.  Fortunately it was easy to get at it, and it was soon produced.  It was a full can, and had never been opened; therefore I gave instructions that, instead of drawing the bung, it should be punctured with a sufficient number of holes to allow the oil to ooze through pretty freely.  This done, I instructed the men to clear away the longboat's painter and to bend it securely round the boat's oars in such a manner as to make a sort of sea-anchor of them, leaving about a fathom of the end of the painter clear to which to bend on the oil-can. Then, when everything was ready, I shouted to Simpson in the gig, telling him what I proposed to do, and giving him his instructions, after which we in the longboat hauled down the jib, and, watching our opportunity, rounded-to, threw overboard our sea-anchor, with the oil- can attached, and took in our remaining canvas.  This business of rounding-to was a very delicate and ticklish job, for had the sea caught us broadside-on we must inevitably have been capsized or swamped; but we were fortunate enough to do everything at precisely the right moment, with the result that the two boats swung round, head-on to the sea, without accident, and without shipping very much water.
