The loss of anchors we had this day sustained, deterred me from any more attempting the small passages through the Barrier Reef; in these, the tide runs with extraordinary violence, and the bottom is coral rock; and whether with, or without wind, no situation can be more dangerous. My anxious desire to get out to sea, and reach the North Coast before the unfavourable monsoon should set in, had led me to persevere amongst these intricate passages beyond what prudence could approve; for had the wind come to blow strong, no anchors, in such deep water and upon loose sand, could have held the ship; a rocky bottom cut the cables; and to have been under sail in the night was certain destruction. I therefore formed the determination, in our future search for a passage out, to avoid all narrow channels, and run along, within side the larger reefs, until a good and safe opening should present itself. This plan, which was dictated by a common regard to safety, might carry us far to the north-west, and delay our arrival in the Gulph of Carpentaria; yet I hoped not; for captain Cook had found the flood tide to come from south-east after passing the Cumberland Islands, whereas before, it ran from the northward; a circumstance which seemed to indicate a termination of the reefs, or a great opening in them., to the north or north-west of those islands. TUESDAY 12 OCTOBER 1802 In the morning., we got under way and steered N. N. W.; but anchored again on finding the flood tide too strong to be stemmed with a light breeze. Our latitude at this tenth anchorage amongst the reefs, was 20° 53' 10", from observations to the north and south, and longitude by time keeper 150° 42' east. At one o'clock our course was resumed, and continued till sunset in clear water; when we came to, in 32 fathoms sand and shells, not far to the south of where the first high breakers had been seen, in the afternoon of the 6th. A dry reef bore N.½ E., distant two and a half, and another E. ½ S. one-and-half miles; and from the mast head others were seen at the back of them, extending from N. W. by N. to near S. E. by E. WEDNESDAY 13 OCTOBER 1802 On going upon deck next morning at daybreak, to get the ship under way, I found her situation different to that wherein we had anchored in the evening. The wind had been light, and as usual in such cases, the cable was shortened in; and it appeared from the bearings, and from the soundings marked every hour on the log board, that between four and five in the morning, the anchor had been lifted by the tide, or dragged, two miles north-east amongst the reefs, from 33 into 28 fathoms; where it had again caught. This change of place had not been perceived; and it was difficult, from the circumstance having occurred at the relief of the watch, to discover with whom the culpable inattention lay; but it might have been attended with fatal consequences.
